38、 WLAN Wireless Local Area Network 4 Heterogeneous Networks Mobility Enhancements Neighbour Cell List (NCL) extension - The size of the inter-frequency neighbour cell list is extended for CELL_DCH, CELL_FACH, CELL_PCH, URA_PCH states and Idle mode, so that network could configure more inter-frequency
39、 neighbour cells than 32 for UE to monitor and detect under massive small cell deployment scenario. Change of best cell on a configured secondary downlink frequency (event 2g) - Event 2g is an inter-frequency measurement event. It is applicable only to the secondary downlink frequency with configure
40、d HS-DSCH operation, and it can be configured on more than one secondary downlink frequency. Enhanced Serving Cell Change for Event 1C - The enhanced Serving Cell Change procedure could also be applied to Event 1C, which is defined in TS 25.308 2. 5 Heterogeneous Networks Enhancements Serving E-DCH
41、cell decoupling - Serving E-DCH cell decoupling is introduced in order to improve the quality of reception of the uplink E-DCH control channels and the E-DCH SI in the presence of strong uplink/downlink imbalance. The UE is configured with different serving HS-DSCH cell and serving E-DCH cell. Radio
42、 Links without DPCH/F-DPCH - The UE is configured with a subset of non-serving E-DCH radio links in the UEs E-DCH active set to operate in the absence of DPCH/F-DPCH. However, a UE is allowed to only receive either E-HICH or both E-HICH and E-RGCH from these non-serving E-DCH cells to mitigate uplin
43、k interference to a cell that is unable to power control a UE in the presence of strong uplink/downlink imbalance. DPCCH2 transmission - In order to improve the quality of reception of the HS-DPCCH in the presence of strong uplink/imbalance, a new secondary uplink pilot channel (DPCCH2) is introduce
44、d in the serving HS-DSCH cell as the reference for the HS-DPCCH channel power. ETSI ETSI TS 125 300 V15.1.0 (2018-07)83GPP TS 25.300 version 15.1.0 Release 156 DCH Enhancements (FDD only) DCH enhancements aims at improving the link efficiency and UE battery performance for voice calls compared to R9
45、9 DCH. DCH enhancements constitutes of the following sub-features: - DL overhead optimization - Enhanced rate matching and transport channel multiplexing - DL Frame Early Termination (DL FET) - Uplink DPCCH with DL FET ACK - Uplink DPDCH dynamic 10ms transmission DCH enhancements supports two modes
46、(Basic and Full). The mode choice controls how the DL Frame Early Termination sub-feature operates, as described in 6.3. All other sub-features are active in both modes. DCH enhancements is only applicable if the TTI of all DCH transport channels on both downlink and uplink is at least 20 ms. If a U
47、E is configured with both CS and PS mapped to the DCH transport channel (in uplink or downlink or both), then DCH enhancements may be configured only when PS has UL:0 and DL:0kbps RAB configuration (3GPP TR 25.993 13). 6.1 DL overhead optimization This sub-feature introduces new DL DPCH slot format
48、by removing the dedicated pilot bits from DL DPCCH and reusing them for DL DPDCH instead. The R99 downlink physical channel (DPCH) consists of 0.66ms slots that contain 2 groups of data (DPDCH) symbols and 3 groups of control (DPCCH) symbols. The size of the groups is determined by the slot format.
49、The control symbol groups are TPC - controlling uplink transmit power, TFCI - specifying the downlink packet type, and dedicated pilot - supporting channel estimation for DL power control and closed-loop transmit diversity. While the TFCI group may be empty in certain slot formats, the pilot and TPC are currently always non-empty. The dedicated pilot bits are used for estimation of DL SIR. With this sub-feature, new DL DPCH slot formats are introduced by removing the dedicated pilot bits and reusing the TPC bits instead for es
