序号	协议内容	解读
1	An NCR includes an NCR-MT entity and an NCR-Fwd entity [19, TS 38.300].	NCR包含NCR-MT和NCR-Fwd
2	Throughout this specification, unless otherwise noted, statements using the term "UE" in Clauses 4 through 13 are equally applicable to the NCR-MT.	除非做特殊说明，本协议中提到“UE”等同于NCR-MT
3	A procedure for the NCR-MT to perform cell search, system information acquisition, random access procedure, UCI reporting, or PDCCH monitoring is same as a corresponding one for a UE. A procedure for the NCR-MT to perform PDSCH reception, CSI-RS measurements and CSI determination, PUSCH transmission, or SRS transmission is same as a corresponding one for a UE as described in [6, TS 38.214].	NCR-MT进行小区搜索、系统信息获取、随机接入、UCI上报、PDCCH监听以及PDSCH接收、CSI-RS测量上报、PUSCH传输、SRS传输的流程与普通UE流程一致。
4	The NCR-Fwd transmits or receives only after the NCR-MT receives on the control link an indication for one or more beams [20, TS 38.106] for the NCR-Fwd to use for transmissions or receptions over corresponding one or more time resources on the access link.	NCR-Fwd的发送或接收仅在NCR-MT在控制链路（C-link)上接收到一个或多个波束的指示，该指示用来确定NCR-Fwd在接入链路(A-link)对应的时域资源上进行发送和接收。
5	The timing for transmission and reception by the NCR-Fwd on the backhaul link follows the frame timing for transmission and reception, respectively, by the NCR-MT.	在回传链路（B-link）上，NCR-Fwd收发的时序信息与NCR-MT收发的帧时序保持相同
6	When the NCR-MT performs a link recovery procedure as described in Clause 6, the NCR-Fwd does not transmit or receive until the link recovery procedure is complete [11, TS 38.321].	当NCR-MT执行链路恢复过程时，NCR-Fwd直到链路恢复过程完成后才进行传输或接收
7	The NCR can be provided, through the NCR-MT, tdd-UL-DL-ConfigurationCommon and can be additionally provided tdd-UL-DL-ConfigurationDedicated. The NCR-Fwd receives on the backhaul link or transmits on the access link only in symbols indicated as downlink by tdd-UL-DL-ConfigurationCommon and, if provided, tdd-UL-DL-ConfigurationDedicated. The NCR-Fwd receives on the access link or transmits on the backhaul link only in symbols indicated as uplink by tdd-UL-DL-ConfigurationCommon and, if provided, tdd-UL-DL-ConfigurationDedicated.	NCR可以通过MCR-MT的高层参数tdd-UL-DL-ConfigurationCommon和 tdd-UL-DL-ConfigurationDedicated配置提供。NCR-Fwd在B-link上接收或在A-link上发送的符号仅由tdd-UL-DL-ConfigurationCommon（或由tdd-UL-DL-ConfigurationDedicated）的下行指示。NCR-Fwd在A-link上接收或在B-link上的发送的符号仅由tdd-UL-DL-ConfigurationCommon（或由tdd-UL-DL-ConfigurationDedicated）的上行指示。
8	If the NCR does not support simultaneous transmissions on control link and the backhaul link, the NCR-Fwd does not transmit over a time resource if the NCR-MT transmits over the time resource.	如果NCR不支持同时在C-link和B-link上传输，NCR-MT传输的时域资源上NCR-Fwd则不传输。
9	When the NCR simultaneously receives via both the control link and the backhaul link in a set of symbols, a TCI state for receptions on the backhaul link is same as a TCI state for receptions on the control link in the set of symbols. When the NCR simultaneously transmits via both the control link and the backhaul link in a set of symbols, a spatial filter for transmissions on the backhaul link is same as a spatial filter for transmissions on the control link in the set of symbols.	当NCR在C-link和B-link的一个符号集上同时接收时，用于B-link上接收符号集的TCI状态同用于C-link上接收的TCI状态相同。当NCR在C-link和B-link的一个符号集上同时发送时，用于B-link上发送符号集的空间滤波器同用于C-link上发送符号集的空间滤波器相同。
10	When the NCR does not simultaneously receive on the control link and the backhaul link - if the NCR does not support determination of a TCI state for receptions on the backhaul link based on an indication of a TCI state by the serving cell, or if the NCR does not receive an indication of a TCI state, for receptions on the backhaul link [11, TS 38.321] - if the NCR does not receive an indication of a unified TCI state for receptions by the NCR-MT, receptions on the backhaul link use same QCL parameters as the ones for PDCCH receptions in a CORESET with the lowest controlResourceSetId in the active DL BWP - else, receptions on the backhaul link use the QCL parameters provided by an indicated unified TCI state for receptions by the NCR-MT - else receptions on the backhaul link use QCL parameters provided by a TCI state in NCR Downlink Backhaul Link Beam Indication MAC CE [11, TS 38.321].	当NCR在C-link和B-link上不同时接收时：-1）如果NCR不支持基于服务小区TCI状态指示来确定用于B-link接收的TCI状态，或者NCR没有收到一个用于B-link接收的TCI状态指示：则如果NCR没有接收用于NCR-MT接收的一个标准TCI状态的指示，B-link上的接收使用与在激活下行BWP上用于PDCCH的最低controlResourceSetId的CORSET相同的QCL参数；否则B-link上的接收使用的QCL参数由用于NCR-MT接收的标准TCI状态指示来提供。-2）否则B-link上的接收使用的QCL参数由在NCR下行B-link波束指示MAC CE 的TCI状态指示来提供。
11	When the NCR does not simultaneously transmit on the control link and the backhaul link - if the NCR does not support determination of a spatial filter for transmissions on the backhaul link based on an indication of a unified TCI state or of an SRI by the serving cell, or if the NCR-MT does not receive an indication of a unified TCI state or of an SRI for determining a spatial filter, for transmissions on the backhaul link - if the NCR does not receive an indication of a unified TCI state for transmissions by the NCR-MT, transmissions on the backhaul link use a same spatial filter as the one associated with the PUCCH resource with the smallest pucch-ResourceId in PUCCH-ResourceSet in the active UL BWP - else, transmissions on the backhaul link use a spatial filter corresponding to the indicated unified TCI state for transmissions by the NCR-MT. - else transmissions on the backhaul link use a spatial filter corresponding to a unified TCI state or an SRI provided in NCR Uplink Backhaul Link Beam Indication MAC CE [11, TS 38.321].	当NCR在C-link和B-link上不同时发送时：-1）如果NCR不支持基于服务小区标准TCI状态指示或SRI来确定用于B-link发送的空间滤波器，或者NCR-MT没有收到由标准TCI状态指示或SRI确定的用于B-link发送的空间滤波器：则如果NCR没有接收到用于NCR-MT发送的标准TCI状态指示，B-link上的发送使用空间滤波器与在激活上行BWP上在PUCCH-ResourceSet中用于PUCCH资源的最小pucch-ResourceId关联的空间滤波器一样；否则B-link上的发送使用由用于NCR-MT发送的标准TCI状态指示对应的空间滤波器。-2）否则B-link上的发送使用在NCR上行B-link波束指示MAC CE 提供的标准TCI状态指示或SRI对应的空间滤波器。
12	If the NCR receives an indication of a TCI state for receptions on the backhaul link in a MAC CE command, or an indication of a unified TCI state or of an SRI for determining a spatial filter for transmissions on the backhaul link in a MAC CE command, the NCR applies the MAC CE command from the first slot that is after slot  where  is the slot where the NCR-MT would transmit a PUCCH with HARQ-ACK information associated with the PDSCH providing the MAC CE command,  is a number of slots per subframe for the SCS configuration  of the PUCCH transmission.	如果NCR在一个MAC CE命令中接收到用来B-link接收的一个TCI状态指示，或者在MAC CE命令中接收到用于B-link发送的标准TCI状态指示或者一个确定空间滤波器的SRI，NCR从时序k+3*N{subfram,u,slot}之后的第一个时序应用MAC CE命令，其中k是NCR-MT发送对应提供MAC CE命令的PDSCH反馈HARQ-ACK的PUCCH信息的时序，N{subfram,u,slot}表示PUCCH传输时SCS配置为u时的每个子帧的时序数。
13	The NCR-Fwd uses a same beam for transmissions and receptions on the access link during respective time resources associated with a same beam index.	NCR-Fwd在相同波束索引对应的各自时域资源上使用相同的波束在A-link上发送和接收。
14	The NCR can be provided by periodicFwdRsrcSetToAddModList a list of sets of resources for transmissions or receptions on the access link. A set of resources, from the list of sets of resources, is provided by NCR-PeriodicFwdResourceSet and occurs with a periodicity provided by periodicityAndOffset-r18. A resource from the set of resources is provided by NCR-PeriodicFwdResource and includes a pair of a time resource provided by periodicTimeRsrc and a beam [20, TS 38.106] with an index provided by beamIndex. The time resource starts at a slot that is offset by a number of slots provided by periodicityAndOffset-r18 from the start of the period for the set of resources and at a symbol that is offset by symbolOffset from the start of the slot, and has a duration provided by durationInSymbols for a SCS provided by referenceSCS and the cyclicPrefix of the active DL BWP.	periodicFwdRsrcSetToAddModList（周期）参数可以为NCR提供一系列用于在A-link上发送和接收的资源集。从资源集列表中的一组资源集由 NCR-PeriodicFwdResourceSet提供、并按参数periodicityAndOffset-r18提供的周期发生。来自资源集中的资源由参数NCR-PeriodicFwdResource提供，其包含一对由参数periodicTimeRsrc提供的时域资源和由参数beamIndex提供的波束及其索引。时域资源开始时序从资源集周期开始时刻和参数periodicityAndOffset-r18提供时序偏置数确定，开始符号由开始时序和参数symbolOffset的偏置数确定，其持续时间由用于SCS的参数durationInSymbols提供，该SCS由激活下行BWP的参数referenceSCS和cyclicPrefix提供。
15	The NCR can be provided by semiPersistentFwdRsrcSetToAddModList a list of sets of resources for transmissions or receptions on the access link and the NCR Access Link Beam Indication MAC CE command can indicate a set of resources for the NCR to use or to stop using based on a corresponding identity provided by semiPersistentFwdRsrcSetId [11, TS 38.321]. The NCR uses or stops using the set of resources starting from the first slot that is after slot  where  is the slot where the NCR-MT would transmit a PUCCH with HARQ-ACK information associated with the PDSCH providing the MAC CE command and  is the SCS configuration for the PUCCH transmission. The set of resources is provided by NCR-SemiPersistentFwdResourceSet and occurs with a periodicity provided by periodicityAndOffset-r18. A resource from the set of resources is provided by NCR-SemiPersistentFwdResource and includes a pair of a time resource provided by semiPersistentTimeRsrc and a beam with an index provided by beamIndex, where beamIndex can be updated by the NCR Access Link Beam Indication MAC CE command. The time resource starts at a slot that is offset by a number of slots provided by periodicityAndOffset-r18 from the start of the period for the set of resources and at a symbol that is offset by symbolOffset from the start of the slot, and has a duration provided by durationInSymbols for a SCS provided by referenceSCS and the cyclicPrefix of the active DL BWP.	semiPersistentFwdRsrcSetToAddModList（半静态）参数可以为NCR提供一系列用于在A-link上发送和接收的资源集，并且NCR A-Link Beam Indication MAC CE命令基于由参数semiPersistentFwdRsrcSetId提供相应标识可以指示用于NCR的资源集使用和停止。NCR使用和停止使用资源集从时序k+3*N{subfram,u,slot}之后第一个时序开始。资源集由NCR-SemiPersistentFwdResourceSet参数提供、其发生的周期由参数periodicityAndOffset-r18提供。从资源集列表中的一组资源集由NCR-SemiPersistentFwdResource参数提供、包括一对由参数semiPersistentTimeRsrc提供的时域资源和由参数beamIndex提供的波束及其索引，其中beamIndex可以由NCR A-Link Beam Indication MAC CE命令更新。时域资源开始时序从资源集周期开始时刻和参数periodicityAndOffset-r18提供时序偏置数确定，开始符号由开始时序和参数symbolOffset的偏置数确定，其持续时间由用于SCS的参数durationInSymbols提供，该SCS由激活下行BWP的参数referenceSCS和cyclicPrefix提供。
16	The NCR-MT can be configured to monitor PDCCH according to USS sets for detection of a DCI format 2_8 with CRC scrambled by an NCR-RNTI. A time resource and a corresponding beam index for transmissions or receptions on the access link are indicated by corresponding fields in DCI format 2_8 [4, TS 38.212]. When the NCR detects more than one DCI formats 2_8 that indicate beam indexes for time resources overlapping in a set of symbols, the NCR uses for the set of symbols a beam index that is indicated by a DCI format 2_8 that the NCR-MT detects in a most recent PDCCH monitoring occasion. If the NCR detects a DCI format 2_8 indicating more than one time resources that overlap in a set of symbols, the NCR expects that beam indexes associated with the more than one time resources have a same value. The time resource starts at a slot that is offset by slotOffsetAperiodic slots from a reference slot and at a symbol that is offset by symbolOffset from the start of the slot, and has a duration provided by durationInSymbols for a SCS provided by referenceSCS and the cyclicPrefix of the active DL BWP. The reference slot is the first slot with the SCS provided by referenceSCS that starts no earlier than the start of a slot that is after a slot of a PDCCH reception that provides the DCI format 2_8 by a number of slots indicated by ncr-AperiodicBeamInd-AccessLink [18, TS 38.306] with the SCS of PDCCH reception.	NCR-MT可以配置为根据USS集监控PDCCH，以用于检测伴有通过NCR-RNTI加扰CRC的DCI format 2_8格式。在A-link中用于发送和接收的时间资源和对应波束索引由DCI format 2_8格式对应的区域指示。当NCR检测到多个指示在符号集上时域重叠的波束索引的DCI format 2_8时，NCR使用的符号集的一个波束索引是由NCR-MT检测出的离PDCCH监控所占位置最近的DCI format 2_8所指示。如果NCR检测到的DCI format 2_8所指示不止一个重叠在符号集的时域资源，NCR期望其多个时域资源相关联波束索引具有相同的值。时域资源开始时序从一个参考时序及参数slotOffsetAperiodic的偏执时序数确定，开始符号由开始时序和参数symbolOffset的偏置数确定，其持续时间由用于SCS的参数durationInSymbols提供，该SCS由激活下行BWP的参数referenceSCS和cyclicPrefix提供。该参考时序是具有由参数referenceSCS提供的SCS的第一个时序，该时序开始时间不早于PDCCH接收器时序后的开始时序，该PDCCH接收器通过具有PDCCH接收器SCS的参数ncr-AperiodicBeamInd-AccessLink所指示的时序数值来提供DCI format 2_8。
17	If - a first time resource provided by NCR-SemiPersistentFwdResourceSet is indicated by the NCR Access Link Beam Indication MAC CE command and is associated with a first beam index, and - a second time resource is provided by NCR-PeriodicFwdResourceSet and is associated with a second beam index, and - the first time resource overlaps with the second time resource in a set of symbols, the NCR applies, for transmissions or receptions on the access link in the set of symbols, the second beam index if only NCR-PeriodicFwdResourceSet includes priorityFlag, and the first beam index otherwise.	如果，-1）第一个时域资源由NCR A-Link Beam Indication MAC CE命令指示的参数NCR-SemiPersistentFwdResourceSet提供，且关联到第一个波束索引，-2）第二个时域资源由参数NCR-PeriodicFwdResourceSet提供并关联到第二个波束索引，-3）第一个时域资源和第二个时域资源在符号集上重叠， 则NCR在A-link符号集上发送或接收时仅当参数NCR-PeriodicFwdResourceSet包含优先级标识priorityFlag时使用第二个波束索引，否则都使用第一个波束索引。
18	If - a first time resource is provided by NCR-PeriodicFwdResourceSet, or provided by NCR-SemiPersistentFwdResourceSet and indicated by the NCR Access Link Beam Indication MAC CE command, and is associated with a first beam index, and - a second time resource is indicated by DCI format 2_8 and is associated with a second beam index provided by the DCI format 2_8, and - the first time resource overlaps with the second time resource in a set of symbols, the NCR applies, for transmissions or receptions on the access link in the set of symbols, - the first beam index if NCR-PeriodicFwdResourceSet or NCR-SemiPersistentFwdResourceSet includes priorityFlag, and - the second beam index if NCR-PeriodicFwdResourceSet or NCR-SemiPersistentFwdResourceSet does not include priorityFlag.	如果，-1）第一个时域资源由NCR-PeriodicFwdResourceSet提供或由NCR A-Link Beam Indication MAC CE命令指示的参数NCR-SemiPersistentFwdResourceSet提供，且关联到第一个波束索引，-2）第二个时域资源DCI format 2_8指示并关联到由该DCI format 2_8提供的第二个波束索引，-3）第一个时域资源和第二个时域资源在符号集上重叠， 则NCR在A-link符号集上发送或接收时使用波束索引为：-1）使用第一个波束索引仅当参数NCR-PeriodicFwdResourceSet或NCR-SemiPersistentFwdResourceSet包含优先级标识priorityFlag时；-2）使用第二个波束索引当参数NCR-PeriodicFwdResourceSet或NCR-SemiPersistentFwdResourceSet均不包含优先级标识priorityFlag。
19	The NCR does not expect overlapping time resources provided by either NCR-PeriodicFwdResourceSet or NCR-SemiPersistentFwdResourceSet to be associated with different beam indexes.	NCR不期望关联到不同波束索引的参数NCR-PeriodicFwdResourceSet或NCR-SemiPersistentFwdResourceSet提供的时域资源重叠。
