在新空口(New Radio，NR)中设计了通过传输配置指示(TransmissionConfiguration Indicator，TCI)状态指示不同信道和/或参考信号的波束的方式。以PDSCH为例，采用无线资源控制(Radio Resource Control，RRC)+媒体接入控制(Medium AccessControl，MAC)-控制单元(Control Element，CE)+下行控制信息(Downlink ControlInformation，DCI)的信令架构指示TCI状态，即RRC配置可用的TCI状态集合，MAC-CE从可用的TCI状态集合中激活一些TCI状态，通过DCI信令，从激活的TCI状态中指示一个TCI状态用于物理下行共享信道(Physical downlink shared channel，PDSCH)解调参考信号(Demodulation Reference Signal，DMRS)的空间接收参数。A manner of indicating different channels and/or beams of reference signals through a transmission configuration indicator (Transmission Configuration Indicator, TCI) state is designed in a new radio interface (New Radio, NR). Taking PDSCH as an example, the signaling architecture of Radio Resource Control (RRC) + Medium Access Control (MAC) - Control Element (CE) + Downlink Control Information (DCI) is adopted Indicate the TCI state, that is, the TCI state set available for RRC configuration, the MAC-CE activates some TCI states from the available TCI state set, and indicates a TCI state from the activated TCI state through DCI signaling for the physical downlink shared channel ( Physical downlink shared channel, PDSCH) demodulation reference signal (Demodulation Reference Signal, DMRS) spatial reception parameters.

相关技术中物理下行控制信道(Physical downlink control channel，PDCCH)、PDSCH、物理上行共享信道(Physical Uplink Shared Channel，PUSCH)、物理上行控制信道(Physical Uplink Control Channel，PUCCH)的波束指示信令是单独设计的，需要不同的信令分别指示PDCCH、PDSCH、PUSCH、PUCCH的波束或空间参数，但在某些情况下，某些信道甚至所有信道采用的波束方向相同，为了节省信令开销和降低指示时延，相关技术引入了统一的TCI架构(Unified TCI)。Unified TCI架构中，通过一个DCI或MAC-CE信令可更新下行信道和/或上行信道的波束，具体分为如下两种模式：In the related art, the beam indication signaling of the Physical Downlink Control Channel (PDCCH), PDSCH, Physical Uplink Shared Channel (PUSCH), and Physical Uplink Control Channel (PUCCH) is a separate Designed, different signaling is required to indicate the beam or spatial parameters of PDCCH, PDSCH, PUSCH, and PUCCH respectively, but in some cases, some channels or even all channels use the same beam direction, in order to save signaling overhead and reduce indication For delay, related technologies introduce a unified TCI architecture (Unified TCI). In the Unified TCI architecture, the beams of the downlink channel and/or uplink channel can be updated through a DCI or MAC-CE signaling, which can be divided into the following two modes:

联合(Joint)TCI：上下行信道的波束方向相同，一个信令同时更新上行+下行信道的波束Joint TCI: The beam directions of the uplink and downlink channels are the same, and one signaling simultaneously updates the beams of the uplink and downlink channels

独立(Separate)TCI：上行信道(PUSCH、PUCCH)的波束方向相同，下行信道(PDSCH、PDCCH)的波束方向相同，但上行信道和下行信道的波束方向不同。一个信令可以更新：1)PDCCH和PDSCH的波束；2)PUSCH和PUCCH的波束；3)PDCCH、PDSCH、PUCCH、PUSCH的波束。Separate TCI: The beam direction of the uplink channel (PUSCH, PUCCH) is the same, and the beam direction of the downlink channel (PDSCH, PDCCH) is the same, but the beam direction of the uplink channel and the downlink channel are different. One signaling can update: 1) PDCCH and PDSCH beams; 2) PUSCH and PUCCH beams; 3) PDCCH, PDSCH, PUCCH, PUSCH beams.

采用joint TCI还是separate TCI模式是由RRC配置的。Unified TCI也采用了RRC+MAC-CE+DCI的信令结构，当RRC配置了多个joint TCI或separate下行(Downlink，DL)/上行(Uplink，UL)TCI状态，MAC-CE信令仅激活了一个TCI状态时，激活的TCI state为选择的TCI；当MAC-CE信令激活多个TCI状态时，通过DCI格式1_1(DCI format1_1)或DCI格式1_2(DCI format1_2)从激活的TCI状态中选择TCI。Whether to use joint TCI or separate TCI mode is configured by RRC. Unified TCI also adopts the signaling structure of RRC+MAC-CE+DCI. When RRC is configured with multiple joint TCI or separate downlink (Downlink, DL)/uplink (Uplink, UL) TCI status, MAC-CE signaling is only activated When a TCI state is activated, the activated TCI state is the selected TCI; when multiple TCI states are activated by MAC-CE signaling, the activated TCI state is activated through DCI format 1_1 (DCI format1_1) or DCI format 1_2 (DCI format1_2). Select TCI.

另一方面，相关技术支持多发送接收节点(multi-TRP)的PDSCH传输，其中S-DCI调度PDSCH传输时，PDSCH重复(repetition)传输方式可分为空分复用(Space DivisionMultiplexing，SDM)，第一频分复用方案(fdmSchemeA)，第二频分复用方案(fdmSchemeB)，第一时分复用方案(tdmSchemeA)，基于时隙的重复方案(slot-based repetitionscheme)，上述传输方式中DCI的TCI域(field)指示1对TCI状态(state)，即1个TCI state对(pair)，MAC-CE可以激活8个TCI state或TCI state pair。On the other hand, related technologies support PDSCH transmission of multiple transmitting and receiving nodes (multi-TRP). When S-DCI schedules PDSCH transmission, the PDSCH repetition (repetition) transmission method can be divided into Space Division Multiplexing (SDM), The first frequency division multiplexing scheme (fdmSchemeA), the second frequency division multiplexing scheme (fdmSchemeB), the first time division multiplexing scheme (tdmSchemeA), the slot-based repetition scheme (slot-based repetition scheme), among the above transmission methods The TCI field (field) of the DCI indicates 1 pair of TCI states (state), that is, 1 TCI state pair (pair), and the MAC-CE can activate 8 TCI states or TCI state pairs.

目前仅考虑了Unified TCI用于single-TRP的场景，计划将Unified TCI扩展到multi-TRP场景(如图1所示)。At present, only the scenario where Unified TCI is used for single-TRP is considered, and it is planned to extend Unified TCI to multi-TRP scenarios (as shown in Figure 1).
