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
38、 downlink frequency with configured 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 Ne
39、tworks Enhancements Serving E-DCH 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
40、cell and serving E-DCH cell. Radio 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-ser
41、ving E-DCH cells to mitigate uplink interference to a cell that is unable to power control a UE in the presence of strong uplink/downlink imbalance. DPCCH2 transmission ETSI ETSI TS 125 300 V14.2.0 (2017-04)83GPP TS 25.300 version 14.2.0 Release 14- In order to improve the quality of reception of th
42、e HS-DPCCH in the presence of strong uplink/imbalance, a new secondary uplink pilot channel (DPCCH2) is introduced in the serving HS-DSCH cell as the reference for the HS-DPCCH channel power. 6 DCH Enhancements (FDD only) DCH enhancements aims at improving the link efficiency and UE battery performa
43、nce for voice calls compared to R99 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 DC
44、H enhancements supports two modes (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 an
45、d uplink is at least 20 ms. If a UE 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 i
46、ntroduces new DL DPCH slot format 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
47、is determined by the slot format. 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 certa
48、in 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 estimating the DL SIR. Corresponding
49、ly, the number of data symbols in a slot is increased leading to less control channel overhead on the downlink. DL closed-loop transmit diversity is not supported when this sub-feature is configured. 6.2 Enhanced rate matching and transport channel multiplexing The physical layer in R99 is designed to carry potentially a large variety of transport blocks with different sizes. The drawback for this design is the rate matching may not be efficient when some transport format combinations are not frequently used. For example, DCC
