34、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 neighbour cells than 32 for UE to monitor and detect under massive small cell deployment scenario. Change of best cell on

35、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 configured HS-DSCH operation, and it can be configured on more than one secondary downlink frequency. Enhanced Serving Cell Change f

36、or 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 cell decoupling - Serving E-DCH cell decoupling is introduced in order to improve the quality of reception of the uplink E-

37、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 Links without DPCH/F-DPCH - The UE is configured with a subset of non-serving E-DCH radio links in the UE“s E-DCH active s

38、et 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 uplink interference to a cell that is unable to power control a UE in the presence of strong uplink/downlink imbalance. DPCCH2

39、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 introduced in the serving HS-DSCH cell as the reference for the HS-DPCCH channel power.

40、 TS 25.300 version 13.1.0 Release 136 DCH Enhancements (FDD only) DCH enhancements aims at improving the link efficiency and UE battery performance for voice calls compared to R99 DCH. DCH enhancements constitutes of the following sub-features: DL overhead optimization Enhanced rate matching and tra

41、nsport channel multiplexing DL Frame Early Termination (DL FET) Uplink DPCCH with DL FET ACK Uplink DPDCH dynamic 10ms transmission DCH 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 s

42、ub-features are active in both modes. DCH enhancements is only applicable for DCH 20 ms TTI on downlink. 6.1 DL overhead optimization This sub-feature introduces new DL DPCH slot format by removing the dedicated pilot bits from DL DPCCH and reusing them for DL DPDCH instead. The R99 downlink physica

43、l 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. The control symbol groups are TPC - controlling uplink transmit power, TFCI - specifying the downlink packet type,

44、 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

45、, new DL DPCH slot formats are introduced by removing the dedicated pilot bits and reusing the TPC bits instead for estimating the DL SIR. Correspondingly, 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

46、 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 efficien

47、t when some transport format combinations are not frequently used. For example, DCCH channel carries non-zero transport blocks not as often as voice DTCH channel. The enhanced rate matching and transport channel multiplexing sub-feature sets a zero rate matching attribute for DCCH, whenever DCCH cha

48、nnel does not carry a transport block together with DTCH channel. The DCCH bit fields are used to transmit DTCH transport channels instead. This potentially improves link efficiency due to less puncturing and better rate matching of the transport block with the available physical channel resources.

49、6.3 DL frame early termination (DL FET) and UL DPCCH with DL FET ACK In a power-controlled system such as R99 DCH, inefficiencies in the power-control loop, such as limited granularity, delays and errors in the feedback, result in the presence of excess SINR at the receiver. This means that packets such as the voice packets which have a long (20ms) transmission time interval (TTI) can often be early-decoded, i.e, decoded prior to reception of all the data symbols in a TTI by running the channel decoder at multiple time in
