Till L14A Feature Operation / Benefits

1. The ACS feature rapidly finds suspected sleeping cells. 2. The feature supports self-healing by automatically trying to recover the suspected sleeping cells. No alarm is sent out if the recovery action is successful but if it fails, an alarm is issued.

1) The basic PDCCH Link Adaptation uses the Physical Downlink Shared Channel (PDSCH) transmission success and a configurable offset to achieve the target Block Error rate (BLER) for PDCCH transmissions. 3) Enhanced PDCCH Link adaptation is based on PDCCH transmission success. It uses the PDSCH Acknowledgement (HARQ-ACK) feedback and the PUSCH detection results to determine whether or not a PDCCH transmission was successful. In addition to achieving the target BLER, it makes efficient use of the PDCCH resources, which allows increased system capacity.

1) If the feature is activated,the cell capacity, measured as number of scheduled PDCCH per TTI, will be increased compared to not using automatic PDCCH Power Boosting, in typical high load VoIP scenarios/conditions, which is on the basis of feature function "automatic PDCCH Power Boost" 2) If the feature is activated to increase the PDCCH PSD level for CCE aggregation level 8, the PDCCH cell coverage will be increased compared to not using PDCCH Power Boost, the feature is especially suitable for TM7/TM8 scenario that PDSCH does not limit cell coverage, but not confined to these two Transmission mode. The feature can be applied to all other transmission modes.

The Maximum Cell Range feature provides support for a maximum cell range of 100 km. Without this feature the maximum cell range is 15 km. Large cells are suitable to obtain coverage in sparsely populated areas where the need for capacity is low. Examples of such areas are deserts, coastal areas, or sea environments. The feature makes it possible to set the cell range between 1 and 100 km. The feature includes use of the random access preamble format 1 that is appropriate for the large round trip times in cells with cell range larger than 15 km.

1. The Interference Rejection Combining feature maximizes the Signal to Interference and Noise Ratio (SINR) of the combined signal by minimizing the noise and interference at the antenna combiner output while preserving the signal. It can be seen as weighting down the signal in the directions of the interferers, so that they do not corrupt the signal from the desired user. 2.The Interference Rejection Combining feature improves the Block Error Rate (BLER) on the Physical Uplink Shared Channel (PUSCH) and Physical Uplink Control Channel (PUCCH) compared to MRC and improves uplink throughput in uplink interference limited systems. The use of IRC on uplink channels does not require any additional User Equipment (UE) support

1. For a UE moving at high speeds with high carrier frequency, the frequency offset estimates based on Physical Uplink Shared Channel (PUSCH) and Physical Uplink Control Channel (PUCCH) are subject to ambiguities and cannot be correctly estimated. High-frequency offset impact on Physical Random Access Channel (PRACH) also causes problems. This is resolved by comparing the frequency offset estimates on PUSCH, PUCCH and PRACH. 2.This feature supports UE speeds of up to 350 km/h for the highest carrier frequencies in the Evolved UMTS Terrestrial Radio Access (E-UTRA) operating bands. This establishes and maintains connections to UE with frequency offsets up to 1900 Hz.

1. Triggered by the UE in RRC_CONNECTED state, resumes the SRB1 and reactivates the AS (3) security without changing algorithms.A successful reestablishment is followed by a RRC Connection Reconfiguration procedure to resume SRB2 and all DRBs. 2.RRC Connection Re-establishment failure happens in the following situations: a) The re-establishment request is initiated towards another cell than the serving cell. b) An ongoing RRC procedure (for example Handover, E-RAB Set up/Release/Modification, UE Context Set up/Release/Modification) exists. The eNodeB responds the UE with a RRC Connection Reestablishment Reject message, the ongoing procedure times out, and the RRC Connection Release is triggered causing the UE to go to the RRC-IDLE state.

The optional feature Multi-target RRC Connection re-establishment Introduces RRC connection re-establishment in other cells than serving cell. The basic feature, RRC Connection Re-establishment, supports only RRC Connection Reestablishment in serving cell. The additional cases where re-establishment is supported by this feature are the following: 1.Re-establishment in another cell of the Serving eNodeB 2.Re-establishment in another cell of another eNodeB, provided that there is an X2 connection and that both eNodeBs are Ericsson eNodeBs 3.Re-establishment during ongoing intra-eNodeB handover (according to the constraints of the previous bullets as well as in Serving cell) 4.Re-establishment during X2 inter-eNodeB handover 5.Re-establishment between different frequencies

Intra-LTE handover can be set to trigger on the RSRP value or the RSRQ value. The measurement reports sent by the UE contains either or both of these values. There are three types of mobility procedures for Intra-LTE handover; intraRBS handover, X2-based inter RBS handover, and S1-based inter-RBS handover. The handover procedures are described in the following: 1.The intra-RBS handover procedure is used when both the source and target cells reside in the same RBS. 2.X2 inter-RBS handover is primarily used when an X2 relation exists between source and target RBSs. Both source and target RBS must be connected to the same MME. 3.S1 inter-RBS handover is primarily used when no X2 relation exists between source and target. Source and target RBS can be connected to the same or different MME. Packet forwarding at S1 Handover is also an optional licensed feature that is used to reduce packet loss.

The objective of data forwarding is to guarantee that packet loss is reduced during an X2 handover and intra-RBS handover, except in the transport network, as well as reducing handover interruption time. The packets forwarded are those stored in the source RBS buffer prior to the handover execution, ,i.e. packets that have not been acknowledged by the UE (only in case of RLC AM DRBs) and packets that have not been transmitted. Source RBS also forwards new incoming packets from the SGW prior to the handover completion. Forwarding occurs only with Packet Data Convergence Protocol (PDCP) Service Data Units (SDUs) in the downlink. In case the feature is active the target RBS prioritizes all downlink PDCP Packet Data Units (PDUs) forwarded by the source RBS, before sending new data received from the S1 link.

The 2 methods of packet forwarding at S1 handover are as follows: Direct Packet Forwarding Data is transferred over the X2 user plane between the source and the target RBS. The source RBS indicates that a direct path is available in the S1-AP handover control signalling to the MME. Indirect Packet Forwarding Data is transferred over the S1 user plane through the source/target Serving Gateway (SGW) between the source and the target RBS. When there is no direct user plane path, the Source RBS does not indicate that a direct path is available in the S1-AP control signalling and this can result in indirect packet forwarding.

This feature makes it possible to change the Serving Gateway (SGW) at X2 handover. This feature enables the core network to balance the network load and utilize network resources more efficiently.

This feature improves the Coverage-Triggered features functionality to increase mobility handling flexibility at poor coverage. It introduces a search zone along the edge of the cell, where User Equipment (UE) measurements search for alternative frequencies and cells.

The measurement process used by the UE to evaluate the serving cell uses parameters sent by the serving eNodeB to the UE. These parameters, sent to the UE in the RRCConnectionReconfiguration messages, include threshold values, hysteresis values, measurement filtering, and time-to-trigger parameters. The UE measurements are reported to the serving eNodeB to make the final decision on redirection to a GERAN / UTRAN /IF / CDMA Target. The Event A2 can base its triggering criterion on either of the following: Reference Signal Received Power (RSRP), representing the mean measured power per reference signal Reference Signal Received Quality (RSRQ), providing an indication of the reference signal quality, especially high inter cell interference The eNodeB will configure two Event A2 measurements in the UE to detect poor coverage, and using the default settings, one of them will be based on RSRP and one on RSRQ. The eNodeB will consider the UE in poor coverage when at least one of the measurements have reported poor coverage. The eNodeB determines whether to release the UE with a redirection to a GERAN / UTRAN /IF / CDMA Target., depending on the UE capabilities, eNodeB licenses, and redirection priority. If the UE is released with a redirection to a GERAN / UTRAN /IF / CDMA Target., the release message contains information about one or several GERAN / UTRAN /IF / CDMA frequencies, to help the UE find a suitable GERAN / UTRAN /IF / CDMA Target cell.

This feature extends the session continuity / CSFB features by including system information for cells belonging to target Radio Access Technology (RAT) when performing Radio Resource Control (RRC) connection release with redirect to GSM or WCDMA . The system information enables the UE to connected to target GSM or WCDMA cell faster.

The feature enables eNodeBs to respond to Circuit Switched (CS) service requests from LTE UE. When an eNodeB receives a request it directs the UE to GERAN or UTRAN frequencies.

The Emergency Call Handling for CS Fallback feature offers the operator the possibility to apply separate priorities for CS fallback for emergency calls as compared to CS fallback for ordinary voice calls. This allows the operator to direct emergency calls to the network that has the best positioning performance and thus comply to the FCC phase 2 requirements on positioning accuracy for such calls

1.That the UE will be transferred to a cell on a different frequency for which the UE has coverage. 2.That an Event A5 (serving becomes worse than threshold1 and neighbor becomes better than threshold2) measurement is configured in the UE whenever there are several candidate target cells, none of which covers the source cell completely. 3.That the UE hands over directly, without an Event A5 measurement, whenever there is (at least) one target cell which is known to cover the source cell completely.

The purpose of the Coverage-Triggered WCDMA IRAT Handover feature is, first, to extend this with the option of initiating a handover to a WCDMA cell, instead of initiating a release. Second, to handle an incoming handover (to an LTE cell) from a WCDMA cell.

The purpose of the Intra-LTE Inter-Mode Handover feature is to manage User Equipment (UE) handover between LTE cells working in different modes – Frequency Division Duplex (FDD) and Time Division Duplex (TDD).

The feature supports The feature supports frequency. The feature supports bands. The feature supports not co-located. The feature supports separate RBSs.

an arbitrary grade of coverage overlap between cells. an arbitrary number of target cells on the same interan arbitrary number of frequencies and frequency load balancing between cells that are co-located and load balancing between cells in the same and in

The purpose of this feature is to offload traffic load above an offload threshold from an EUTRAN cell to an Ericsson or non-Ericsson EUTRAN FDD or TDD cell.

The 6 Cell Support feature offers reduced equipment cost by controlling six cells with one DU in one RBS node. This enables cost efficient ways of building networks in many scenarios. The capacity of the DU can be fully used with six-sector single carrier configurations. One DU can carry the traffic of up to six cells.

The 4x2 Quad Antenna Downlink Performance Package feature provides support for four transmit antennas used for 4-way transmit diversity and spatial multiplexing, to improve downlink coverage, capacity that is, bitrate, and throughput

The 4x2 Quad Antenna Downlink Performance Package feature provides support for four transmit antennas used for 4-way transmit diversity and spatial multiplexing, to improve downlink coverage, capacity that is, bitrate, and throughput The Dual-Antenna Downlink Performance Package feature must be active prior to introducing the 4x2 Quad Antenna Downlink Performance Package feature The Quad Antenna Uplink Performance Package feature provides support for four receive antennas used for 4-way receive diversity, to improve uplink coverage, capacity (bit rate) and throughput. Quad Antenna Uplink Performance is possible for all antenna configurations with four antennas and for any number of radio units.

The QoS-Aware Scheduler feature allows configuration of the scheduler on a QCI basis. This can be used to configure absolute priority scheduling for Data Radio Bearers (DRBs) in regard to air interface resources. It also enables configuration of scheduling algorithms per QCI, given that appropriate scheduler licenses are in place. 2.When there is no license available for the QoS-Aware Scheduler feature, the system scheduler sets to Resource Fair (RF) as default.

The QoS-Aware Scheduler feature must be activated.

The Uplink Frequency-Selective Scheduling feature is dependent on sounding. Sounding is a procedure which utilizes a set of uplink reference signals. Unlike the uplink Demodulation Reference Signals (DMRS), which are sent within the same bandwidth as the uplink signal, Sounding Reference Signals (SRS) can be sent over almost arbitrary channel bandwidths, providing the channel estimation over any part of the spectrum. This gives the possibility of scheduling uplink transmission on resource blocks of instantaneously good quality.

The default mobility parameters in the Radio Base Station (RBS) are not necessarily optimized when the operators deploy the network. An RBS with poor mobility parameters encounters the following problems: Too Early Handover Too Late Handover Handover to Wrong Cell Ping-pong Handover This feature provides RBS with the capacity to automatically calibrate the mobility parameters, and enables the operator to observe the occurrence of these problems. This feature reduces the number of radio connection failures and unnecessary handovers, which subsequently increases the RBS throughput, as well as the VoIP and Streaming service quality.

The End-User Bitrate Shaping feature takes the UL Aggregated Maximum Bitrate (AMBR) for the non-Guaranteed Bitrate (GBR) bearer and the UL Maximum Bitrate (MBR) for each GBR bearer as input. Therefore, in the UL it is possible to shape the traffic to the sum of the maximum aggregated bitrate for a specific User Equipment (UE) (AMBR) and the MBR for each GBR bearer of that UE

Efficient DRX/DTX for Connected UE feature is provided as a licensed feature and allows DRX for UE in RRC_CONNECTED mode.

The Enhanced Cell ID Control Plane Location Support feature in the RBS enables the operator to keep the location node updated, through OSS-RC, about the geographic data of the cells served by the RBS The Enhanced Cell ID User Plane Location Support feature in the RBS enables the operator to keep the location node updated, through OSS-RC, about the geographic data of the cells served by the RBS

The Multiple Radio Bearers per User feature permits User Equipment (UE) to establish as many as eight simultaneous data radio beare

E/// - Combined function of below 2 features can be mapped with NSN feature LTE1035 . Enhanced PDCCH Link Adaption - In order to satisfy the required BLER for PDCCH, the estimated SINR must be adjusted to compensate for the CQI estimation errors on the PDCCH. It uses the PDSCH Acknowledgement (HARQ-ACK) feedback and the PUSCH detection results to determine whether or not a PDCCH transmission was successful.Based on the estimated SINR plus the calculated outer loop adjustment and the transport block size, the link adaptation determines the number of CCEs required for the coming PDCCH transmission PDCCH Power Boost - CCE aggregation level and boost value based on CCE cost and PDCCH SINR from PDCCH link Adaptation feature. UE at any cell position is supported to calculate corresponding CCE Aggregation level and boost power.PDCCH power per OFDM symbol is another limitation, if the total power including boost power exceeds the limitation, it is forbidden to use the boosted power.

Feature Operation / Benefits

This feature raises an indication that there may be a problem, so the operator must still check the situation in the cell and decide, which actions are to trigger.

Recovery Action will be carried out through this feature.

LTE979 implements IRC (Interference Rejection Combining) algorithm aims to maximize SINR by balancing amplification of the power of the desired signal and suppression of the interference caused by other signals. IRC algorithm may be visually explained as forming a receiving beam in the direction of the wanted user, while nulls of the receiving beam pattern are formed towards the interferer. This is done with maximization of SINR in mind, so effectively the max gain may not be in the direction of the wanted UE.MRC on the other hand aims in maximization of wanted UE signal, ignoring the interferers. . The basic rule of thumb is that the number of ( RX antennas - 1) dominant interferers can be suppressed. This means, for 2 RX antennas 1 dominant interferers can be suppressed. This is only a rough rating since also interference from more users can be suppressed but the suppressor gain will decrease very rapidly.

1.LTE48: Support of high speed users the evolved Node B (eNB) is able to handle user equipment’s speed (UE) of up to 350 km/h in open space and 300 km/h in tunnels. 2.It is possible to configure a cell to support high-speed users by setting PrachHsFlag to true. It makes that restricted set for physical random access channel (PRACH) preambles is used and the PRACH radio receiver (Rx) algorithm is changed to high speed receiver. In addition, the PRACH high speed receiver produces some frequency offset estimation for each UE.

1. Successful RRC connection re-establishment is supported in source cell during ongoing RRC or S1AP procedures. In this use case re-establishment can be successful, when UE initiates the re-establishment procedure due to radio link failure (according to 3GPP 36.331, section 5.3.11.3) or due to integrity check failure. 2.The UE initiates RRC connection re-establishment procedure. The UE performs cell selection and sends a re-establishment request to the eNB. Based on the information received in the request, the eNB checks that the UE context exists, performs security and integrity check and verifies that the PhysCellId within the ReestabUEIdentity is equal to the PCI of the source cell. If all conditions are met, the eNB accepts the request and the Re-establishment procedure is performed.

If all conditions are met, the eNB accepts the request and the Re-establishment procedure is performed.

The eNodeB supports RRC Connection Release with redirection to an operatorspecifiable RAT & frequency if the UE risks losing coverage and no handover is possible. Due to RSRP measurements (event A2), the eNodeB then triggers a RRC connection release with redirect. The thresholds for this event are operator configurable. The target frequency is also operator configurable. It can belong to eUTRAN, WCDMA, GSM, eHRPD, CDMA/1xRTT. The UE capabilities are considered for the redirect. The redirect functionality can be enabled/disabled via O&M. Up to six redirection target layers MORED are supported for each profile MOPR.

lte1407: RSRQ Based Redirect feature, the eNB configures in the UE additional to the existing RSRP - based A2 for redirect an RSRQ based A2 event on the own serving cell. A2 event means: the serving cell becomes worse than an absolute threshold. When the UE sends this A2-RSRQ event and when it is received by the eNB, an RRC Connection Release with Redirect is triggered at the UE by the eNB. he scope of the feature is to redirect UEs with poor RSRQ, but with a good RSRP, where neither a handover nor an RSRP-based redirect triggers to another radio access technology (RAT) layer, which is outside of the strong interference area .It is strongly recommended that only UEs with a quiet low RSRQ value, which is almost against the lowest one of -19dB is considered for redirect to another RAT. This is to avoid ping-long effects back from these RATs into LTE. The same measurement-object and related Id as for the serving frequency as for RSRP triggered redirect must be used for RSRQ-based triggered redirect.

This feature introduces additional funcionality for CS Fallback with Redirection to GERAN (LTE562: CS Fallback with redirection), Emergency calls handling (LTE22: Emergency Calls handling) and UE Context Release with Redirection (LTE423: RRC Connection Release with Redirect). With this feature the eNB provides System Information (SI) for GERAN cells inside redirection message. This reduces time needed to access target GERAN cell, in which CS service will be performed, as the UE will not need to read SIBs from air interface to access target cell. The cell selection algorithm in the UE is not influenced by providing the GERAN system information, for example the UE does not prefer GERAN cells for which system information has been provided.

The feature “lte22: Emergency Call Handling” re-uses LTE562 to provide regulatory requirements in initial phase of LTE implementation. To grant proper handling of emergency call UE will be redirected from LTE to another CS capable RAT (WCDMA or GSM). This action is triggered by MME sending CS Fallback High Priority indication to eNB. As a consequence UE will be redirected to another RAT by reusing LTE562 solution (but with a separately configurable UE priorities dependent RedirectedCarrierInfo IE). In addition, one separate admission threshold is used for UEs sending RRC CONNECTION REQUEST message with establishmentCause set to 'emergency'.

1. LTE1387 is designed to move incoming load from a highly-loaded cell to lowloaded cells using different frequency bands within the same eNB [ GBR, nonGBR load (exchange only between same eNB 3.Suitable candidate cells are sorted according to load information exchanged between cells of same eNB 4.Suitable candidate cells are sorted according to load information exchanged between cells of same eNB 5.Elimination of Unsuitable LTE Handover Target Cells due to Target cells whose load is too high (load above target, AC=0) & Target cell not served by same eNB as serving cell 6.Intra-eNB handover is prepared towards the chosen target cell Handover Cause “Reduce load in serving cell”. Admission Control shall be applied in the same way as described for “HO due to radio reasons”
