39、he present document, the following terms and definitions apply. Blind HARQ retransmissions for HSDPA (FDD): A HARQ operation where a UE in CELL_DCH state supports reception of MAC-hs/ehs PDU within 5 sub-frames from the reception of the previous MAC-hs/ehs PDU intended for the same HARQ process. Dat
40、a block: The data transmitted to one UE on HS-DSCH in one transport block (one or two transport blocks are transmitted per TTI in single and dual stream transmission respectively per HS-DSCH, three transport blocks are transmitted per TTI in three streams transmission per HS-DSCH and four transport
41、blocks are transmitted per TTI in four streams transmission per HS-DSCH). ETSI ETSI TS 125 308 V14.0.0 (2017-05)83GPP TS 25.308 version 14.0.0 Release 14Priority class: One flow of data within a HS-DSCH transport channel. One HS-DSCH can transport several priority classes (no more priority classes p
42、er TTI than the number of transport blocks). There is only one priority class per TTI (MAC-hs only) or several priority classes per TTI (MAC-ehs only). HARQ Process: Peer state machines capable of achieving error correction by retransmission. One process can be used only for one data block at a time
43、. HARQ Entity: Consists of all the HARQ processes of a UE for one HS-DSCH transport channel, controlling part or all the available soft buffer capacity. Serving HS-DSCH radio link: The radio link that the HS-PDSCH physical channel(s) allocated to the UE belongs to. Serving HS-DSCH cell: The cell ass
44、ociated with the UTRAN access point performing transmission and reception of the serving HS-DSCH radio link for a given UE. The serving HS-DSCH cell is always part of the current active set of the UE. Serving HS-DSCH Node B: A role a Node B may take with respect to a UE having one or several HS-PDSC
45、Hs allocated. The serving HS-DSCH Node B is the Node B controlling the serving HS-DSCH cell. HS-SCCH set: a set of HS-SCCH which is used for HS-PDSCH allocation. There is a maximum of four HS-SCCHs in a given HS-SCCH set. There can be multiple HS-SCCH sets in one cell. HS-SCCH sets are independent,
46、i.e. they can overlap or have no intersection. Serving HS-SCCH set: the HS-SCCH set being used by a given UE for HS-PDSCH allocations. MAC-d flow: a MAC-d flow is a flow of MAC-d PDUs which belong to logical channels which are MAC-d multiplexed. Common MAC Flow: a Common MAC Flow is a flow of MAC-c
47、PDU mapped to HS-DSCH configured for UEs in Cell_FACH. Paging MAC Flow: a Paging MAC Flow is a flow of MAC-c PDU mapped to HS-DSCH configured for UEs in Cell_PCH and URA_PCH. Multiflow: A mode of operation with two simultaneous HS-DSCH transport channels per carrier frequency, where the HS-DSCH tran
48、sport channels may belong to the same or different Node Bs. Assisting serving HS-DSCH Cell: In addition to the serving HS-DSCH cell, a cell in the same frequency, where the UE is configured to simultaneously monitor a HS-SCCH set and receive HS-DSCH if it is scheduled in that cell. Assisting seconda
49、ry serving HS-DSCH Cell: In addition to the serving HS-DSCH cell, a cell in the secondary downlink frequency, where the UE is configured to simultaneously monitor a HS-SCCH set and receive HS-DSCH if it is scheduled in that cell. Designated non-serving HS-DSCH cell: The non-serving HS-DSCH cell from which the UE estimates the F-DPCH quality for TPC derivation, when the UE is configured with DPCCH2 in the uplink or the Serving E-DCH cell decoupling is configured. The TPC is transmitted on UL DPCCH. Serving E-DCH cell decoupling (FDD only): An E-
