Description

本申请实施例涉及移动通信技术领域，具体涉及一种无线通信方法及装置、通信设备、存储介质。
背景技术
在第三代移动通信伙伴项目(3rd Generation Partnership Project，3GPP)协议中提出了传输配置指示(Unified Transmission Configuration Indication，TCI)状态(state)的概念，用于下行的空间域准共址(Quasi Co-Location，QCL)的波束指示，以及时域频域的QCL信息的传递。QCL用于描述从一个源参考信号指向一个目标参考信号的大尺度衰落的关系。对于波束指示来说，当用户设备(User Equipment，UE)在从网络设备(Network，NW)得到源参考信号和目标参考信号的QCL关系后，可以使用接收源参考信号的接收波束接收目标参考信号。但是TCI state的指示机制仅适用于下行的信道和信号。为了提供一个统一的上下行波束管理机制，提出了统一(unified)TCI状态(state)的概念，但是unified TCI state将上行信道和下行信道统合到相同的波束上，仅针对单发射接收点(Single Transmission Reception Point，sTRP)，不适用多发射接收点(Multiple Transmission Reception Point，mTRP)的场景。

为便于理解本申请实施例的技术方案，以下对本申请实施例的相关技术进行说明，以下相关技术作为可选方案与本申请实施例的技术方案可以进行任意结合，其均属于本申请实施例的保护范围。
TCI state的指示机制仅适用于下行的信道和信号，且在NR系统中应用起来有诸多的限制。为了给NR系统提供一个统一的上下行波束管理机制，3GPP提出了统一TCI state的概念，统一TCI state增加了重要新功能，比如：
●设计了2种unified TCI state的模式： 联合(joint)TCI state，适用于上下行的信道和信号；独立(Separate)DL/UL TCI state，DL TCI state仅适用于下行的信道和信号，UL TCI state仅适用于上行的信道和信号，这种模式下上下行的波束可以分开来控制。
●下行信道(物理下行控制信道(Physical Downlink Control Channel，PDCCH)，物理下行共享信道(Physical Downlink Shared Channel，PDSCH))和信号(非周期信道状态信息-参考信号(Channel State Information Reference Signal，CSI-RS)使用相同的下行发射波束，该下行发射波束使用DL TCI state或joint TCI state指示。
●上行信道(物理上行控制信道(Physical Uplink Control Channel，PUCCH)，物理上行共享信道(Physical Uplink Shared Channel，PUSCH))和信号(探测参考信号(Sounding Reference Signal，SRS)使用相同的上行发射波束，上行发射波束使用UL TCI state或joint TCI state指示。
●Unified TCI state可以使用媒体接入控制控制单元(Media Access Control Control Element，MAC CE)和/或下行控制信息(Downlink Control Information，DCI)动态更新和指示。
●适用于载波聚合的场景，单载波单元(Component Carrier，CC)上的波束指示可以适用于多个不同的CC。
●上行的波束指示可以和上行的功率控制参数通过UL TCI state或joint TCI state同时给出。
●支持小区间的波束管理功能。
对于统一TCI state，这里的“统一”有很多层的含义。第一层的含义是统一了上行和下行的波束指示机制，TCI state仅用来做下行的波束指示，上行的波束指示使用了基于空间关系信息(Spatial relation information)的信令。第二层的含义是不同信道间的波束统一，例如，在Separate DL/UL TCI state的配置下，UE将PDCCH(UE专属)和PDSCH(UE专属)统一成相同的波束来传输，UE将PUCCH和PUSCH使用相同的波束来传输。在Joint TCI state的配置下，UE认为上行和下行的不同信道和信号可以有很好的波束对称性的保证，即对上下行使用对称的波束对来进行通信。
TCI state、QCL和统一TCI state的RRC参数配置可包括如下：
Figure PCTCN2022106294-appb-000001
Figure PCTCN2022106294-appb-000002
目前，统一TCI state并未支持多TRP(Multi-TRP或mTRP)。
下面，对mTRP的传输方案进行介绍。
需要说明的是，在第17版本(Rel.17)中，mTRP传输都是使用第15版本(Rel.15)或第16版本(Rel.16)定义的TCI state，并非第17版本中定义的unified TCI state。
Multi-TRP PDCCH的传输方案
在第15版本中，NR支持了最基础的PDCCH传输，即sTRP PDCCH传输方式。其中，设定了时域上的配置，如搜索空间集合(Search Space Set，SSS)，以及其关联的控制信道所在的资源集合即控制信道资源集(Control Resource Set，CORESET)等。
在第17版本中，NR支持了mTRP的PDCCH重复(repetition)传输方案；在同一个版本中，也支持了PDCCH的系统帧号(System Frame Number，SFN)的传输方式。
在PDCCH重复的传输方式中，相同的PDCCH以时分复用(time-division multiplexing，TDM)的方式从多个TRP以不同的波束来传输。如图2所示，TRP1对应的CORESET 1和TRP2对应的CORESET 2各自有其激活的波束方向，即TCI state 1和TCI state 2。CORESET 1和CORESET 2有其各自关联的Search Space Set，分别是Search Space Set 1和Search Space Set 2，这两个Search Space Sets通过RRC信令进行直接的关联。UE使用CORESET 1和Search Space Set 1接收来自TRP1的PDCCH 1，并使用CORESET 2和Search Space Set2接收来自TRP2的PDCCH 1，在收到来自TRP 1的PDCCH 1后，可以与来自TRP 2的PDCCH 1进行合并，然后进行盲检测并解码该PDCCH。
在PDCCH SFN传输方式中，相同的PDCCH或PDSCH从多个TRP以不同的波束来传输。如图3所示，用来估计多普勒频移的跟踪参考信号(Tracing Reference Signal，TRS)是通过TRP专属的方式来传输，不同的TRP使用不同的时域或频域资源来传输TRS，UE的PDCCH和PDSCH则是通过SFN的传输，即NW使用相同的时频资源来发送完全一样的PDCCH或PDSCH，只是由于不同的TRP所处的空间位置不同而使用不同的发射波束，即TCI states不同。
不同于sTRP PDCCH和PDCCH repetition传输方式，PDCCH SFN传输方式使用的CORESET(s)需要被激活两个TCI states，分别用于不同的TRP，sTRP PDCCH和PDCCH repetition传输方式的CORESET仅使用一个TCI state。
Multi-TRP PUCCH的传输方案
在第17版本中，NR支持了PUCCH面向多TRP的TDM重复传输。这里的TDM指的是PUCCH的重复传输在时间上是不重叠的。第17版本支持了时隙(slot)内和slot间的重复传输。一个PUCCH资源可以被MAC CE激活1个或2个Spatial Relation Information，即最多2个上行发射波束。UE根据所使用的PUCCH资源的Spatial Relation Information的个数来判断是否进行mTRP传输。
在一示例中，一个PUCCH资源可以被MAC CE激活2个Spatial Relation Information：Spatial Relation Information1和Spatial Relation Information2的情况下，如图4所示，UE使用Spatial Relation Information1指示的上行发射波束向TRP1发送PUCCH1，并使用Spatial Relation Information2指示的上行发射波束向TRP2发送PUCCH1。
Multi-TRP PUCSH的传输方案
同样是在第17版本的协议中，支持了slot间的PUSCH面向mTRP的重复传输。NW可以配置最多2个SRS资源集，并在上行调度DCI中指示一个或两个SRS资源集来告知UE进行sTRP PUSCH还是mTRP PUSCH的传输，其中，一个SRS资源集对应一个TRP。在该上行调度DCI中，NW还会指示被指示的SRS资源集中的特定SRS资源，UE根据该特定SRS资源的最近一个slot内的波束方向来发送PUSCH。
为了更好地说明PUSCH repetition，如图5所示，在PDCCH A的DCI中指示两个SRS资源集：SRS资源集0和SRS资源集1，且SRS资源集0对应TRP 1，SRS资源集1对应TRP 2，UE通过SRS资源集0中被选中的SRS资源A向TRP 1发送PUSCH1，且通过SRS资源集1中被选中的SRS资源B向TRP2来发送PUSCH1。
如果直接把unified TCI state套用到multi-TRP的场景下，有一个问题是需要解决的，那就是unified TCI state在一个CC/带宽部分(Bandwidth Part，BWP)内有强大的统合能力，即把下行PDCCH/PDSCH/CSI-RS，上行的PUCCH/PUSCH/SRS等都统合到相同的波束上，但unified TCI state针对的是一个TRP， 一个TRP只需要一套上下行波束，但在mTRP场景下，至少需要有2套独立的上下行波束来对应空间上分隔的TRP。
因此，如果在MAC CE或MAC CE+DCI信令中指示了1个或2个unified TCI state，上下行信道进行mTRP传输时如何来分配指示的unified TCI state为需要解决的问题。

在网络设备指示一个统一TCI状态的情况下，终端设备基于该统一TCI状态执行单TRP传输，即与一个TRP进行通信。
下面，对本申请实施例提供的无线通信方法进行进一步描述。
本申请实施例提供的无线通信方法，在UE被配置且被指示了一个或多个unified TCI state时，且UE工作在mTRP的场景下，各个不同的上下行信道如何使用指示的统一TCI state。
对于PDCCH，PDCCH传输控制信息，负责调度上下行的数据信道，即DCI格式1_1/1_2用来调度下行数据信道PDSCH，DCI格式0_1/0_2用来调度上行数据信道PUSCH。
随后，则考虑被调度的PDSCH和PUSCH的波束指示情况。
对于PUCCH，因为有些PUCCH资源是被下行调度DCI所使用的，该PUCCH用来承载被调度的PDSCH的HARQ-ACK信息。但也有些PUCCH是以半静态的方式被UE使用的。如承载周期性(P)/半永久性(SP)CSI的PUCCH，UE自己触发的来承载调度请求Scheduling request，SR)的PUCCH。
最终，对于不同的信道以及组合(如PDCCH SFN传输和sTRP PDSCH)，前者属于mTRP传输，后者属于sTRP传输，我们允许这样的组合存在。因为NR系统中需要这样的调度灵活性的存在。但对于一个或多个被指示的统一TCI state，本申请实施例提供的无线通信方法的效果是来自同一个TRP的信道，如PDCCH和PDSCH都是使用相同的下行发射波束；对于发送到同一个TRP的信道，如PUCCH和PUSCH，UE都使用相同的上行发射波束。这里的波束相同仅仅是针对TRP-specific而言。并非要求PDCCH和PDSCH的波束从cell-specific的角度看完全一致。
对于S-DCI中指示/更新的一个或多个unified TCI state，因为是基于MAC CE激活的码点，每一个码点可以对应一个或两个unified TCI state。当一个码点包含2个unified TCI states时，unified TCI states出现的在MAC CE中有先后顺序，我们可以认为(MAC CE从上到下来读取)先出现的unified TCI state为第一，第二出现的unified TCI state为第二。
对于M-DCI中指示/更新的unified TCI state，每一个DCI中都会指示一个unified TCI state。所以，本申请实施例给出如下的定义作为后续方案的基础。
在serving cell配置了Joint TCI state pool的时候，约定MAC CE可以激活第一Joint TCI state(对应第一TRP)和第二Joint TCI state(对应第二TRP)；
如果serving cell配置了separate DL/UL TCI state pools，那么MAC CE可以激活第一DL TCI state和第一UL TCI state(对应第一TRP)和第二DL TCI state和第二UL TCI state(对应第二TRP)。
实施例1、对于PDCCH的Unified TCI state的指示/更新
对于不同的PDCCH传输方式，以往的NR版本中支持了基础的sTRP PDCCH传输，以及在Rel.17中增强的PDCCH Repetition和SFN PDCCH。本申请实施例尽量按照统一的方式处理不同的PDCCH传输方案，但也考虑各个传输方式所使用波束的不同。
实施例1.1、基于RRC配置的DL/Joint TCI state分配
这里，基于RRC信令对CORESET group/Search Space Set Group的分组方式来分配指示的第一DL/Joint TCI state和/或第二DL/Joint TCI state。
基于RRC信令对CORESET/Search Space Set的标签方式来跟随指示的第一DL/Joint TCI state和/或第二DL/Joint TCI state。
这里，包括以下两种方案：
方案1、基于CORESET的RRC配置方案
不同于M-DCI mTRP操作，PDCCH repetition、sTRP PDCCH和SFN PDCCH都不会被NW配置RRC参数CORESETPoolIndex，这样也就没有办法隐式地标识一个TRP。虽然这样做好处是NW可以从任意TRP发送一个PDCCH，但UE却无法知道到底是哪个TRP发送了PDCCH，UE仅根据PDCCH被指示的TCI state来进行接收。
在mTRP的操作中，NW会指示一个或两个或更多个DL/Joint TCI state，且每一个TCI state都会对应一个TRP。在CJT(Coherent Joint Transmission)的操作模式下，最多可以支持4个TRP一起为UE进行联合的相干传输。因此，NW有必要告知UE，一个或多个指示的DL/Joint TCI state是如何与TRP进行对应的，这样UE才可以将一个或多个指示的DL/Joint TCI state来进行对应上下行信道的接收和/或发送。
本申请实施例考虑采用RRC信令的方式来进行预先配置。即在unified TCI state指示之前，就告知UE哪些控制信道的资源是属于哪个TRP。这样UE在后续接到指示的unified TCI state之后，可以将控制信道的波束对应到相应的TRP上。
这里，在S-DCI multi-TRP操作的场景下，NW可以将PDCCH所有可能占用的多个CORESET分为2个CORESET组，这2个CORESET组可以被标识为第一CORESET组和第二组CORESET。如果某一个CORESET未被显示地分组，可以认为默认地属于第一CORESET组。这样CORESET组正好一一对应我们定义的指示的第一DL/Joint TCI state和第二DL/Joint TCI state。需要说明的是，在以往的协 议中，PDCCH对应的发射波束是以CORESET为单位来进行配置和激活的。
另外一种对于CORESET的处理方式是，不把CORESET进行直接的分组，而是通过RRC信令将每一个CORESET标识，它应该去跟随(follow)被指示的一个或多个DL/Joint TCI state。比如说，一个CORESET可以被配置为去follow：
·第一DL/Joint TCI state或
·第二DL/Joint TCI state或
·第一和第二DL/Joint TCI state或
·NW可以配置该CORESET不去跟随任何指示的unified TCI state
对于最后一种情况(即CORESET不去跟随任何被指示的unified TCI state)，确实有其特例在Rel.17中，如果unified TCI state包含的参考信号是来自非服务小区或邻近小区的SSB，那么UE非专属的控制信道只能使用本服务小区的下行参考信号作为DL/Joint TCI state。因此，最后一项是指CORESET可以不去跟随Rel.17定义的unified TCI state，而是去跟随(follow)Rel.15/16中定义的信令方式所指示的TCI state。
对于sTRP PDCCH和PDCCH repetition的传输方式，每个CORESET只能有一个传输的波束，因此对于这些PDCCH所在的CORESET的RRC配置只能是跟随第一或第二DL/Joint TCI state，或干脆不去跟随被指示的TCI state。但对于PDCCH SFN传输方案来说，CORESET是被不同的TRP在相同的时频资源上用不同的波束来发送，一个CORESET需要被激活两个不同的下行发送波束。因此，对于SFN PDCCH的CORESET，NW应该用RRC信令来指示它去跟随第一DL/Joint TCI state和第二DL/Joint TCI state。
在一示例中，CORESET的资源配置信息包括的信息如下：
Figure PCTCN2022106294-appb-000003
其中，coresetGroupID指示该CORESET所属的CORESET组，followIndicatedTCIstate指示该CORESET关联或跟随的统一TCI state。
如图9所示，TRP1的传输资源为第一传输资源，第一传输资源可为包括CORESET1或SSS1，第一传输资源属于第一传输资源组，且第一传输资源组跟随第一被指示的统一TCI状态；TRP2的传输资源为第二传输资源，第二传输资源可为包括CORESET2或SSS2，第二传输资源属于第二传输资源组，且第二传输资源组跟随第二被指示的统一TCI状态；在PDCCH重复传输模式下，第一传输资源用于TRP1，第二传输资源用于TRP2，则TRP1使用第一指示的统一TCI状态在第一传输资源上传输数据流，TRP2使用第二指示的统一TCI状态在第二传输资源上传输数据流。在PDCCH SFN模式下，第一传输资源用于TRP1和TRP2，或者第二传输资源用于TRP1和TRP2，则TRP1使用第一指示的统一TCI状态且TRP2使用第二指示的统一TCI状态同时在第一传输资源或第二传输资源上传输数据流。
方案2、基于Search Space Set的RRC配置方案
本申请实施例中，还可以通过RRC信令配置PDCCH可能占用的多个CORESET所关联的多个Search Space Set。
多个Search Space Set可以被标识为第一Search Space Set组和第二Search Space Set组，第一Search Space Set组和第二Search Space Set组一一对应指示的第一DL/Joint TCI state和第二DL/Joint TCI state。
Search Space Set也可以被配置跟随一个或多个指示的DL/Joint TCI state。举例来说，该Search Space Set可以被配置跟随第一DL/Joint TCI state、或第二DL/Joint TCI state、或第一和第二DL/Joint TCI state、或不去跟随被指示的unified TCI state。
本申请实施例中，Search Space Set和CORESET的对应关系是一对一的映射。在Search Space Set和CORESET的对应关系为多对一的映射，即多个Search Space Set可以关联到同一个CORESET上的情况下，一个激活的BWP上可以配置最多3个CORESET和最多10个Search Space Set。所以NW在配置Search Space Set和CORESET关联关系的时候应该足够慎重，如果2个Search Space Set关联到同一个CORESET，其这两个Search Space Set去跟随的波束不一致(一个SSS跟随第一DL/Joint TCI state，另一个SSS跟随第二DL/Joint TCI state)，那么UE在接收的时候会出现不必要的困惑。
在一示例中，SSS的资源配置信息如包括的信息下：
Figure PCTCN2022106294-appb-000004
Figure PCTCN2022106294-appb-000005
其中，controlResourceSetId指示该SSS对应的CORESET，searchSpaceSetGroupID指示该SSS关联的SSS组，followIndicatedTCIstate指示该SSS关联或跟随的统一TCI state。
考虑不同的PDCCH传输方案，对于sTRP PDCCH和PDCCH repetition的传输方式，每个CORESET只能有一个传输的波束，那么该CORESET所关联的Search Space Set的RRC配置只能是跟随第一或第二DL/Joint TCI state，或干脆不去跟随被指示的TCI state。但对于PDCCH SFN传输方案来说，CORESET是被不同的TRP在相同的时频资源上用不同的波束来发送，这个CORESET所关联的Search Space Set需要被激活两个不同的下行发送波束。因此，NW应该用RRC信令来指示它去跟随第一DL/Joint TCI state和第二DL/Joint TCI state。
实施例1.2、基于固定方式配置的DL/Joint TCI state指示
基于固定方式对CORESET/Search Space Set所适用的第一DL/Joint TCI state和/或第二DL/Joint  TCI state进行分组。
本申请实施例中，也可以考虑协议中固定的方式来给PDCCH来分配指示的一个或多个DL/Joint TCI state。同样可以分为CORESET和Search Space Set两种方式。
假设MAC CE或MAC CE+DCI指示了两个DL/Joint TCI states，如果PDCCH是sTRP PDCCH或PDCCH repetition的传输方式(CORESET/Search Space Set只需要一个激活的TCI state)，那么默认地CORESET/Search Space Set去跟随第一被指示的DL/Joint TCI state。当然，这里也可以默认地去跟随第二被指示的DL/Joint TCI state，仅仅是一个规则而已，并没有技术上的不同；如果PDCCH是SFN PDCCH的传输方式(CORESET/Search Space Set需要两个激活的TCI state)，那么默认地CORESET/Search Space Set去跟随第一和第二被指示的DL/Joint TCI state。
假设MAC CE或MAC CE+DCI仅指示了1个DL/Joint TCI state，如果PDCCH是sTRP PDCCH或PDCCH repetition的传输方式(CORESET/Search Space Set只需要一个激活的TCI state)，那么默认地CORESET/Search Space Set去跟随这个指示的DL/Joint TCI state(这里就不需要再去区分第一或第二DL/Joint TCI state)。如果PDCCH是SFN PDCCH的传输方式(CORESET/Search Space Set需要两个激活的TCI state)，那么这时SFN PDCCH无法进行，UE可以理解为一种NW指示的错误情况(Error Case)，UE不期望这种情况的发生。
实施例1.3、基于MAC CE激活的DL/Joint TCI state分配
基于RRC信令配置为较为静态的方案。在本申请实施例中，可使用较为灵活的MAC CE，前提是在RRC信令配置的基础上MAC CE来进行相应的调整。下面我们介绍两种MAC CE的设计，正好对应RRC配置的两种机制。
第一种、基于MAC CE信令对CORESET group/Search Space Set Group的分组方式来分配指示的第一DL/Joint TCI state和/或第二DL/Joint TCI state。
第一种MAC CE，至少应该包含如下的信息：
●服务小区标识(Serving cell ID)
●带宽部分标识(BWP ID)
●CORESET组标识(CORESET Group ID)/SSS组标识(Search Space Set Group ID)
●跟随(Indicate to follow)
○第一下行/联合TCI state(1 st DL/Joint TCI state)or
○第二上行/联合TCI state(2 nd DL/Joint TCI state)or
○第一下行/联合TCI state和第二上行/联合TCI state(Both DL/Joint TCI states)or
○空(None)
这里，空可理解为保留状态，即不跟随第一下行/联合TCI state或第二上行/联合TCI state。
从上述MAC CE中的信息，UE可以解读出在一个CC/BWP上的CORESET组或Search Space Set组是去跟随指示的第一DL/Joint TCI state、或第二DL/Joint TCI state、或第一DL/Joint TCI state和第二DL/Joint TCI state(Both DL/Joint TCI states)、或不去跟随任何unified TCI state。
第二种、基于MAC CE信令对CORESET/Search Space Set的标签方式来跟随指示的第一DL/Joint TCI state和/或第二DL/Joint TCI state。
不同于第一种MAC CE的地方在于把控制的精度从CORESET group/Search Space Set group变成了CORESET/Search Space Set。从形式上，MAC CE至少应该包含如下的信息：
●Serving cell ID
●BWP ID
●CORESET ID/Search Space Set ID
●Indicate to follow
○1 st DL/Joint TCI state or
○2 nd DL/Joint TCI state or
○Both DL/Joint TCI states or
○None
实施例1.4、基于DCI的一个或多个DL/Joint TCI state分配
基于DCI动态信令的CORESET/Search Space Set的unified TCI state分配方式
考虑在上下行调度DCI中(如DCI格式1_1和1_2做下行调度)引入一个新的域来指示PDCCH所在的CORESET或CORESET Group或Search Space Set或Search Space Set Group来跟随(follow)哪个指示的DL/Joint TCI state。
当然，这里也可以考虑把这个功能来进行外延，即被这个PDCCH所调度的数据信道PDSCH/PUSCH，控制信道PUCCH，以及参考信号如非周期CSI-RS和非周期SRS等也去跟随和PDCCH一样的unified  TCI state。
这里，可以命名这个新的域为FollowIndicatedTCIStatePDCCH。，码点(codepoints)设计和UE的对应行为可以参考表1。这个域指示UE应该去接收从哪个TRP发来的PDCCH。
表1、码点设计和UE的对应行为的关系
Figure PCTCN2022106294-appb-000006
实施例2、对于PSDCH的一个或多个Unified TCI state(的指示/更新
实施例2.1、第一DL/Joint TCI state和/或第二DL/Joint TCI state的跟随方案
对于PDCCH所调度的PDSCH，PDSCH所使用DL/Joint TCI state最简单的一个策略就是跟随调度它的PDCCH所使用的DL/Joint TCI state，即对于同一个下行发送的TRP，UE使用相同的下行接收波束来接收PDCCH和PDSCH。
实施例2.2
考虑到PDCCH不同的传输方式和PDSCH传输方式的组合，以及PDCCH所使用的一个或多个指示unified TCI state，对于PDSCH所使用的一个或多个指示unified TCI state的方案包括：
假设MAC CE或MAC CE+DCI仅指示了2个DL/Joint TCI state：
·如果PDSCH是来自mTRP的传输(不管是DCI动态指示，还是NW提前进行的配置，如半静态PDSCH)，那么不管调度DCI的传输方式(sTRP或mTRP)，UE使用指示的第一和第二DL/Joint TCI state来进行PDSCH的接收；
·如果PDSCH是来自sTRP的传输，那么需要考虑调度DCI所在的CORESET或Search Space Set所使用的波束，即第一DL/Joint TCI state还是第二DL/Joint TCI state。UE使用与PDCCH相同的指示DL/Joint TCI state来接收PDSCH；当然，这里的前提是CORESET/Search Space Set是使用了unified TCI state，而不是Rel.15/16中定义的TCI state。
假设MAC CE或MAC CE+DCI仅指示了1个DL/Joint TCI state：
·如果PDSCH被配置为来自mTRP的传输，不管调度DCI的传输方式(sTRP或mTRP)，UE可以理解这种来自NW的自相矛盾的指示是一种错误情况(error case)，UE不期望收到这样的指示。
·如果PDSCH是被调度指示来自sTRP的传输，那么UE使用NW指示的第一或第二DL/Joint TCI state来接收PDSCH即可。
实施例3、对于PUSCH的一个或多个Unified TCI state的指示/更新
基于RRC信令的第一和/或第二SRS资源集和第一和/或第二UL/Joint TCI state的关联关系和上行波束的指示方案。
在Rel.17中，支持了PUSCH mTRP在时域的重复传输，其波束方向是跟随第一和/或第二SRS Resource Set中被上行调度DCI所指示的SRS资源的波束方向。如前所述，在unified TCI state被NW配置和指示的情况下，UE被NW指示第一和/或第二UL/Joint TCI state。
实施例3.1、基于RRC信令关联SRS resource set和UL/Joint TCI state
我们设计高层的RRC信令来关联(基于码本或非码本用途的)SRS资源集和NW所指示的一个或多个unified TCI state来进行基于TDM的PUSCH重复传输。具体来说，RRC信令可以配置第一SRS资源集来关联第一指示的UL/Joint TCI state，第二SRS资源集来关联第一指示的UL/Joint TCI state。当然这种配置关系也可以在配置的时候进行交叉，如第一SRS资源集来关联第二指示的UL/Joint TCI state。
这样，UE在收到现有上行mTRP PUSCH传输调度的时候，可以选择按照现有协议的方式来在时域的不同的transmission occasions发送基于TDM的PUSCH。例如，在第一个PUSCH transmission occasion，UE朝向TRP#1(SRS资源集#1关联第一UL/Joint TCI state)发送第一个时域的PUSCH occasion；然后在第二个PUSCH transmission occasion，UE朝向TRP#2(SRS资源集#2关联第二UL/Joint TCI state)发送第二个时域的PUSCH occasion。
如果UE收到的上行sTRP PUSCH传输调度时，即UL DCI中仅给出一个SRS资源集。那么UE也可以找到该SRS资源集所关联的第一或第二UL/Joint TCI state来进行传输。
实施例3.2、基于RRC信令关联PUSCH传输occasion和UL/Joint TCI state
除了上述将SRS资源集关联指示unified TCI state的方案，我们还可以想到将PUSCH重复传输的 transmission occasion直接关联到指示的第一和第二UL/Joint TCI states。对于transmission occasion这个词可以理解为传输在时域上的发生的机会，一般是由NW调度或预先配置上行传输资源才会发生。
具体来说，第一PUSCH transmission occasion关联到NW指示的第一UL/Joint TCI state；第二PUSCH transmission occasion关联到NW指示的第二UL/Joint TCI state；当PUSCH重复传输的次数大于2时，比如说4或8repetitions，这种方式可以作为一个最小的单位来进行扩展。第三PUSCH transmission occasion关联到NW指示的第一UL/Joint TCI state；第四PUSCH transmission occasion关联到NW指示的第二UL/Joint TCI states。以此类推。
实施例3.3、基于MAC CE更新的关联关系
基于MAC CE信令的第一和/或第二SRS资源集和第一和/或第二UL/Joint TCI state的关联关系和上行波束的指示方案。
对于上述RRC信令关联关系(SRS资源集和指示的UL/Joint TCI state)，这属于一种半静态的配置方式。为了更好地增加PUSCH传输的灵活性，在RRC配置的基础上，本申请实施例还考虑引入MAC CE的方式来改变这种关联关系，比如将第一SRS资源集所关联第一指示的UL/Joint TCI state，更改为第二指示的UL/Joint TCI state。
那么MAC CE应该至少包含如下信息
●Serving cell ID
●BWP ID
●SRS resource set ID
●Indicate to follow
○第一上行/联合TCI state(1 st UL/Joint TCI state)or
○第二上行/联合TCI state(2 ndUL/Joint TCI state)or
○None
实施例4、对于PUCCH的一个或多个Unified TCI state的指示/更新
在Rel.17中引入了PUCCH TDM repetition面向2TRP的传输方案。每个PUCCH资源都可以被MAC CE激活1个或2个上行发射波束，即Spatial Relation Information。
实施例4.1、对于所有PUCCH资源的UL/Joint TCI state指示方案
全部PUCCH资源来跟随指示的第一和/或第二UL/Joint TCI state的方案
在Rel.18中，需要增强基于UL/Joint TCI state的PUCCH传输方案，其实可以做到很简单的实现，即MAC CE或MAC CE+DCI中指示的1个或2个UL/Joint TCI state来给所有的PUCCH资源使用。如果指示了1个UL/Joint TCI state，那么UE在该指示的unified TCI state适用的CC/BWP上，进行所有PUCCH资源的sTRP传输，不管该PUCCH资源是用来承载HARQ，信道状态信息(Channel State Information，CSI)还是SR。如果指示了2个UL/Joint TCI state，那么UE在该指示的unified TCI state适用的CC/BWP上，进行所有PUCCH资源的mTRP传输。
该PUCCH传输方案可以是同时进行的(如SDM或FDM)，也可以是分时进行的(如TDM)PUCCH repetition。
该PUCCH传输方案可以是同时进行的(如SDM或FDM)，也可以是分时进行的(如TDM)PUCCH repetition。
实施例4.2、基于PUCCH resource group的UL/Joint TCI state指示方案
PUCCH资源组来跟随指示的第一和/或第二UL/Joint TCI state的方案
除了上述将所有的PUCCH资源都使用一套第一和/或第二UL/Joint TCI state，还有一种更为灵活的方式是NW将PUCCH资源通过RRC信令分成若干组，即PUCCH资源组(PUCCH resource group)，如一个PUCCH resource group可以包含最多64个PUCCH资源，有最多4个PUCCH resource group。
NW在此设计的基础上，可以最多指示4组第一和/或第二UL/Joint TCI state，分别一一对应到4个PUCCH resource group。这里的对应关系可以是NW通过RRC信令配置。
在一示例中，PUCCH资源组和统一TCI状态可通过以下信息设置：
Figure PCTCN2022106294-appb-000007
pucch-ResourceGroupId-r16指示PUCCH资源组，followIndicatedTCIstate指示该PUCCH资源组关联或跟随的统一TCI状态。
另外，在RRC信令配置的基础上，通过MAC CE信令来进行更新/指示，也可以作为一种可行的方案。在一示例中，MAC CE可以至少包含如下信息：
●Serving cell ID
●BWP ID
●PUCCH resource ID/PUCCH resource group ID
●Indicate to follow
○1 st UL/Joint TCI state or
○2 nd UL/Joint TCI state or
○Both UL/Joint TCI states or
○None
需要说明的是如果该MAC CE中指示的第三项是PUCCH资源ID，那么该PUCCH资源所在的PUCCH resource group中的所有PUCCH资源都会更新其跟随的unified TCI state。
