42、oses of the present document, the terms and definitions given in TR 21.905 1 and the following apply. A term defined in the present document takes precedence over the definition of the same term, if any, in TR 21.905 1. Active Time: Time related to DRX operation, as defined in subclause 5.7, during
43、which the MAC entity monitors the PDCCH. mac-ContentionResolutionTimer: Specifies the number of consecutive subframe(s) during which the MAC entity shall monitor the PDCCH after Msg3 is transmitted. DRX Cycle: Specifies the periodic repetition of the On Duration followed by a possible period of inac
44、tivity (see figure 3.1-1 below). Figure 3.1-1: DRX Cycle drx-InactivityTimer: Specifies the number of consecutive PDCCH-subframe(s) after the subframe in which a PDCCH indicates an initial UL, DL or SL user data transmission for this MAC entity. drx-RetransmissionTimer: Specifies the maximum number
45、of consecutive PDCCH-subframe(s) until a DL retransmission is received. drxShortCycleTimer: Specifies the number of consecutive subframe(s) the MAC entity shall follow the Short DRX cycle. drxStartOffset: Specifies the subframe where the DRX Cycle starts. drx-ULRetransmissionTimer: Specifies the max
46、imum number of consecutive PDCCH-subframe(s) until a grant for UL retransmission is received. HARQ information: HARQ information for DL-SCH or for UL-SCH transmissions consists of New Data Indicator (NDI), Transport Block (TB) size. For DL-SCH transmissions and for asynchronous UL HARQ, the HARQ inf
47、ormation also includes HARQ process ID. For UL-SCH transmission the HARQ information also includes Redundancy Version (RV). In case of spatial multiplexing on DL-SCH the HARQ information comprises a set of NDI and TB size for each transport block. HARQ information for SL-SCH and SL-DCH transmissions
48、 consists of TB size only. HARQ RTT Timer: This parameter specifies the minimum amount of subframe(s) before a DL HARQ retransmission is expected by the MAC entity. Msg3: Message transmitted on UL-SCH containing a C-RNTI MAC CE or CCCH SDU, submitted from upper layer and associated with the UE Conte
49、ntion Resolution Identity, as part of a random access procedure. onDurationTimer: Specifies the number of consecutive PDCCH-subframe(s) at the beginning of a DRX Cycle. PDCCH: Refers to the PDCCH 7, EPDCCH (in subframes when configured), MPDCCH 2 or, for an RN with R-PDCCH configured and not suspended, to the R-PDCCH. PDCCH-subframe: Refers to a subframe with PDCCH. For a MAC entity not configured with any TDD serving cell(s), this represents any subframe; for a MAC entity configured with at least one TDD serving cell, if a
