技术领域
本公开涉及通信技术领域，尤其涉及一种指示信息的传输方法及通信设备。
背景技术
相关技术中，在物理下行共享信道(Physical downlink shared channel，PDSCH)的波束指示机制中，网络设备使用无线资源控制(Radio Resource Control，RRC)信令在高层参数PDSCH-Config内配置M个传输配置指示状态(Transmission Configuration Indicator state，TCI state)，其中M值依赖于终端的能力参数capability maxNumberActiveTCI-PerBWP。每个TCI state中包括PDSCH解调参考信号(Demodulation Reference Signal，DMRS)端口和参考信号(reference signal)之间的准共址(quasi co-location，QCL)关系。
网络设备可以通过发送媒体接入控制控制单元(Medium Access Control Control Element，MAC CE)命令激活和去激活上述配置的TCI state。在相关技术中的协议TS38.321中，通过MAC协议数据单元(Protocol Data Unit，PDU)具有逻辑信道标识(Logical Channel ID，LCID)的子头subheader来识别PDSCH MAC CE专有命令，该命令用于激活或者去激活TCI States，该命令最多激活8个TCI state。
网络设备通过DCI中的传输配置指示域(TCI field)来对PDSCH的波束信息进行指示，即TCI field(通常为3bit)的每个码点codepoint对应这上述MAC CE激活的最多8个TCI state中的1个。终端根据接收PDCCH上的DCI，获知接收PDSCH所用的波束信息。
上述MAC CE命令具有可变比特长度，其中的各field如下：
服务小区标识(Serving Cell ID):指示MAC CE所应用到的Serving Cell identity，长度5bits；
部分带宽标识(BWP ID):指示MAC CE所应用到的DL BWP，长度2bits；
Ti:如果存在TCI-StateId i的TCI state，则Ti用于指示TCI-StateId i的TCI state的激活/去激活状态；否则MAC实体忽略该field。Ti field设置为1，则指示TCI-StateId i的TCI state被激活，且映射到DCI中TCI field的codepoint。Ti field设置为0，则指示TCI-StateId i的TCI state被去激活，且不映射到DCI中TCI field的codepoint。TCI state所映射到的codepint是根据在Ti field中设置为1的所有TCI state的顺序位置所确定的，即Ti field中设置为1的第一个TCI state映射到codepoint值0，Ti field中设置为1的第二个TCI state映射到codepoint值1，以此类推。激活TCI state的最大数量为8。
R:预留的bit，设置为0。
目前仅给出了MAC CE命令指示的TCI state与DCI中TCI field的码点一一映射的设计方案，这样无法满足多传输接收点(Transmission Reception Point，TRP)等通信场景中TCI信息的指示需求。。
发明内容
本公开实施例提供一种指示信息的传输方法及通信设备，以解决相关技术中的MAC CE命令指示的TCI state无法满足多TRP等通信场景中TCI信息的指示需求的问题。
第一方面，本公开实施例提供一种指示信息的传输方法，包括：
传输媒体接入控制控制单元MAC CE命令，所述MAC CE命令用于指示激活N个第一对象以及所述第一对象与下行控制信息DCI中传输配置指示域TCI field的码点的映射关系；所述N个第一对象包括M个传输配置指示状态TCI state组中的TCI state和N-M个TCI state，N为正整数，M为小于或等于N的整数。
第二方面，本公开实施例还提供一种通信设备，包括：
传输模块，用于传输媒体接入控制控制单元MAC CE命令，所述MAC CE 命令用于指示激活N个第一对象以及所述第一对象与下行控制信息DCI中传输配置指示域TCI field的码点的映射关系；所述N个第一对象包括M个传输配置指示状态TCI state组中的TCI state和N-M个TCI state，N为正整数，M为小于或等于N的整数。
第三方面，本公开实施例还提供一种通信设备，包括：存储器、处理器及存储在所述存储器上并可在所述处理器上运行的程序，所述程序被所述处理器执行时实现上述指示信息的传输方法中的步骤。
第四方面，本公开实施例还提供一种计算机可读存储介质，所述计算机可读存储介质上存储有计算机程序，所述计算机程序被处理器执行时实现上述指示信息的传输方法的步骤。
本公开实施例通过在MAC CE命令指示激活第一对象时，同时指示了第一对象与下行控制信息DCI中传输配置指示域TCI field的码点的映射关系，从而可以通过MAC CE命令指示激活TCI state和/或TCI state组中的TCI state，这样可以实现DCI中TCI field的每个码点对应1个或多个TCI state。因此本公开实施例提供的指示信息的传输方法可以支持多TRP等通信场景中的TCI信息指示的需求。

应理解，网络可以同时发送多个MAC CE命令，不同的MAC CE命令可以指示不同的内容。本实施例中，N个第一对象包括Q个TCI state和M个TCI state组中的TCI state时，指示激活Q个TCI state的MAC CE命令与指示激活M个TCI state组中的TCI state的MAC CE命令是相互独立的命令。此外，激活Q个TCI state的指示可以在一个MAC CE命令上指示，也可以在多个MAC CE命令上指示；同样的，激活M个TCI state组中的TCI state的指示可以在一个MAC CE命令上指示，也可以在多个MAC CE命令上指示。
在一可选实施例中，所述MAC CE的预留比特位用于指示所述第一对象与下行控制信息DCI中传输配置指示域TCI field的码点的映射关系。例如，当预留比特位为0时，指示激活TCI state与DCI中TCI field的码点一一映射； 当预留比特位为1时，指示激活TCI state组中的TCI state与DCI中TCI field的码点一一映射。
本实施例中，TCI state组可以包括一个或者多个TCI state，也就是说，当预留比特位为1时，可以指示激活一个或者多个TCI state映射到DCI中TCI field的一个码点。
需要说明的是，本公开实施例通过MAC CE命令指示激活N个第一对象后，在RRC信令配置的TCI state中除激活N个第一对象之外的其余TCI state都可以理解为处于非激活状态。
本公开实施例通过在MAC CE命令指示激活第一对象时，同时指示了第一对象与下行控制信息DCI中传输配置指示域TCI field的码点的映射关系，从而可以通过MAC CE命令指示激活TCI state和/或TCI state组中的TCI state，这样可以实现DCI中TCI field的每个码点对应1个或多个TCI state。因此本公开实施例提供的指示信息的传输方法可以支持多TRP等通信场景中的TCI信息指示的需求。
进一步的，基于上述实施例，本实施例中，当M大于0时，所述MAC CE命令包括第一MAC CE命令，所述第一MAC CE命令用于指示激活M个TCI state组中的TCI state以及所述M个TCI state组中的TCI state与DCI中TCI field的M个码点对应。
在本公开实施例中，所述第一MAC CE命令包括第一比特域，所述第一比特域用于指示激活M个TCI state组中的TCI state。具体的，对于TCI state组中的TCI state的指示方式可以根据实际需要进行设置，以下对此进行详细说明。
第一可选实施方式中，所述第一比特域包括所述M个TCI state组中的TCI state的标识信息，各所述TCI state的标识信息按照TCI state组的排列顺序依次排列，且同一TCI state组中的TCI state的标识信息连续。具体的，第一比特域的bit格式可以表示为：
TCI state ID1,1，……，TCI state ID1,H，
TCI state ID2,1，……，TCI state ID2,H，
……，
TCI state IDM,1，……，TCI state IDN,H。
其中，TCI state IDm,h表示第m个TCI state组中第h个TCI state的标识信息，m为小于或等于M的正整数，h为小于或等于H的正整数，H为TCI state组中TCI state数量，且各TCI state组的TCI state数量相同。
需要说明的是，通过TCI state的标识信息指示激活TCI state组中的TCI state时，MAC CE命令中指示的标识信息对应的TCI state处于激活状态，除MAC CE命令中指示的标识信息之外的其他TCI state的标识信息对应的TCI state处于去激活状态。
应理解，当所述M个TCI state组中存在至少两个TCI state组中的TCI state数量不同时，为了方便终端识别TCI state的分组，还可以添加TCI state组标识(即TCI state group ID)。也就是说，当所述M个TCI state组中存在至少两个TCI state组的TCI state数量不同时，在每一TCI state组中的所有TCI state的标识信息之前或者之后添加对应的TCI state组标识。此时，上述第一比特域的bit格式可以表示为：
Group ID1，TCI state ID1,1，……，TCI state ID1,H1，
Group ID2，TCI state ID2,1，……，TCI state ID2,H2，
……，
Group IDM，TCI state IDM,1，……，TCI state IDM,HM。
或者，上述第一比特域的bit格式可以表示为：
TCI state ID1,1，……，TCI state ID1,H1，Group ID1
TCI state ID2,1，……，TCI state ID2,H2，Group ID2
……，
TCI state IDM,1，……，TCI state IDM,HM，Group IDM。
其中，Group IDm表示第m(m为小于等于M的正整数)个TCI state组的TCI state组标识，Hm为第m个TCI state组中TCI state数量，H1～HM中至少有两个数值不等。应理解，当TCI state组标识位于对应的TCI state组的所有TCI state的标识信息之前时，第一个TCI state组的TCI state组标识可以省略；当TCI state组标识位于对应的TCI state组的所有TCI state的标识信息之后时，第M个TCI state组的TCI state组标识可以省略。也就是说，在相 邻的两个TCI state组之间添加一个分组标识即可。
在第二可选实施方式中，所述第一比特域包括依次排列的H个第一子比特域，每个所述第一子比特域包括M个第二子比特域；H为各TCI state组中TCI state数量的最大值；
其中，第i个第一子比特域中的第j个第二子比特域包括第j个TCI state组中的第i个TCI state的标识信息，i为小于或等于H的正整数，j为小于或等于M的正整数。
本实施方式中，上述第一比特域的bit格式可以表示为：
TCI state ID1,1，TCI state ID2,1，……，TCI state IDM,1，
TCI state ID1,2，TCI state ID2,2，……，TCI state IDM,2，
……，
TCI state ID1,H，TCI state ID2,H，……，TCI state IDM,H。
在第三可选实施方式中，所述第一比特域包括依次排列的H个第一子比特域，每个所述第一子比特域包括M个第二子比特域；H为各TCI state组中TCI state数量的最大值。特别的，各TCI state组中的TCI state数量相同；
其中第一个第一子比特域按照位图指示激活所述M个TCI state组中的第一个TCI state；第i个第一子比特域中的第j个第二子比特域包括第j个TCI state组中的第i个TCI state的标识信息，i为大于1、且小于或等于H的整数，j为小于或等于M的正整数。
本实施例方式中，上述第一个第一子比特域的比特数量与网络设备为终端配置的TCI state的个数相同，例如RRC信令配置的TCI state的个数为128，则第一个第一子比特域包括128bit。其中，128bit中包括M个bit的值为1，其余bit的值为0。bit的值为1指示该bit对应的TCI state为激活状态；bit的值为0，指示该bit对应的TCI state为去激活状态。
需要说明的是，当所述M个TCI state组中存在至少两个TCI state组中的TCI state数量不同时，在第一TCI state组中添加A个目标比特序列，所述第一TCI state组包括B个TCI state，A与B的和值等于各TCI state组中TCI state数量的最大值。
本实施例中，上述所述目标比特序列包括协议约定的比特序列或所述B 个TCI state中的TCI state的标识信息。协议约定的比特序列为特殊比特序列，即为无效的比特序列。例如以H的取值为2为例进行说明，例如第一个TCI state组包括一个TCI state，其标识信息为TCI state ID1,1，此时通过添加目标比特序列后，可以得到第一个TCI state组包括{TCI state ID1,1，特殊比特序列}，或者第一个TCI state组包括{TCI state ID1,1，TCI state ID1,1}。
此时，在上述第一比特域中，除了指示有效的TCI state的标识信息，还指示了无效的目标比特序列。
在第四可选实施方式中，所述M个TCI state组中TCI state数量相同的TCI state组在一个第一MAC CE命令中指示。
由于在每个第一MAC CE命令中指示的TCI state组中包含相同数量的TCI state，这样终端可以识别每一MAC CE命令中的TCI state的分组。
具体的，对于每一MAC CE命令中第一比特域的比特格式可以参照上述实方式，在此不再赘述。
进一步的，当M小于N时，所述MAC CE命令还包括第二MAC CE命令，所述第二MAC CE命令用于指示激活所述N-M个TCI state以及所述N-M个TCI state与DCI中TCI field的N-M个码点对应。
在本公开实施例中，所述第二MAC CE命令包括目标比特域，该目标比特域用于通过位图(bitmap)的方式指示多个TCI state的激活状态，其中，每一个比特位用于指示对应的TCI state的激活状态。目前最多指示8个TCI state的激活状态，也就是说，上述目标比特域中值为“1”的比特数量最多为8。
需要说明的，每一所述TCI state组包括至少一个TCI state。其中M个TCI state组中各TCI state组的TCI state数量可以全部相同、部分相同或者全部不同。也就是说，在一可选实施例中，所述M个TCI state组中存在至少两个TCI state组中的TCI state数量相同。在另一可选实施例中，所述M个TCI state组中存在至少两个TCI state组中的TCI state数量不同。
应理解，在本公开实施例中，上述TCI state可以用于确定PDSCH等下行信道或者下行参考信号的波束信息。
为了更好的理解本公开，以下对本公开的具体实现过程进行详细说明。
1、网络设备通过RRC信令配置K个TCI state。
2、网络设备发送用于激活/去激活PDSCH的TCI state的MAC CE命令。
3、网络设备发送物理下行控制信道(Physical Downlink Control Channel，PDCCH)给终端，在DCI的TCI field指示了PDSCH的TCI state信息。
其中，用于激活PDSCH的TCI state的MAC CE命令包括以下几种方案。
方案1：
利用预留bit的R的不同值，来指示激活的TCI state与DCI中TCI field的codepoint的映射关系。
R设置为0，表示使用相关技术中的方式，即该MAC CE所激活的TCI state最多为8个，且每个激活的TCI state映射到DCI中TCI field的一个codepoint。
R设置为1，表示使用本公开方式，即该MAC CE所激活的TCI state最多为N组(例如相关技术中N最大为8)，每组包括M个TCI state(对照相关技术，M取值为2。作为扩展，后续技术演进可支持M取值大于2)，且每组激活的TCI state映射到DCI中TCI field的一个codepoint。
情况1，在该MAC CE命令中，在BWP ID field之后的bit用于指示激活N*M个TCI state，具体的bit格式可以为：
TCI state ID1,1，……，TCI state ID1,M，
TCI state ID2,1，……，TCI state ID2,M，
……，
TCI state IDN,1，……，TCI state IDN,M。
情况2，在该MAC CE命令中，在BWP ID field之后的bit用于指示N*M个TCI state，具体的bit格式可以为：
TCI state ID1,1，……，TCI state IDN,1，
TCI state ID1,2，……，TCI state IDN,2，
……，
TCI state ID1,M，……，TCI state IDN,M。
情况3，在该MAC CE命令中，在BWP ID field之后的bit采用相关技术中Ti的bitmap方式指示激活每组TCI state中的第一个TCI state，在指示完 每组TCI state中的第一个TCI state之后的bit用TCI state ID方式来指示各组TCI state中其它的激活TCI state。
方案2：
利用预留bit的R的不同值，来指示激活的TCI state与DCI中TCI field的codepoint的映射关系。
R设置为0，表示使用相关技术中的方式，即该MAC CE所激活的TCI state最多为8个，且每个激活的TCI state映射到DCI中TCI field的一个codepoint。
R设置为1，表示使用本公开方式，即该MAC CE所激活的TCI state最多为N组(例如相关技术中N最大为8)，每组包括最多M个TCI state(对照相关技术，M取值为2。作为扩展，后续技术演进可支持M取值大于2)，也就是说，每组激活的TCI state中可以把包括1个或多个TCI state，且每组激活的TCI state映射到DCI中TCI field的一个codepoint。
情况1，设M为2，对于包括1个激活TCI state的TCI state组，可以在该TCI state组中增加一个特殊的比特序列，与所述1个TCI state成为1个TCI state组。
如，第一组TCI state包括{TCI state ID1,1，特殊比特序列}，映射到DCI中TCI field的一个codepoint。
情况2，设M为2，对于包括1个激活TCI state的TCI state组，在该TCI state组中重复使用M个激活的1个TCI state，成为1个TCI state组。
如，第一组TCI state包括{TCI state ID1,1，TCI state ID1,1}，映射到DCI中TCI field的一个codepoint。
情况3，增加TCI state group ID，此时上述第一比特域的bit格式可以表示为：
Group ID1，TCI state ID1,1，……，TCI state ID1,M1，
Group ID2，TCI state ID2,1，……，TCI state ID2,M2，
……，
Group IDN，TCI state IDN,1，……，TCI state IDN,MN。
或者，上述第一比特域的bit格式可以表示为：
TCI state ID1,1，……，TCI state ID1,M1，Group ID1
TCI state ID2,1，……，TCI state ID2,M2，Group ID2
……，
TCI state IDN,1，……，TCI state IDN,MN，Group IDN。
其中，M1，M2，……，MN为各TCI state组中的TCI state数量。
方案3：
利用预留bit的R的不同值，来指示激活的TCI state与DCI中TCI field的codepoint的映射关系，并且将多个MAC CE命令的激活TCI state联合起来，映射到DCI中TCI field的codepoint。例如，利用第一MAC CE命令指示激活TCI state，利用第二MAC CE命令指示激活TCI state组中的TCI state。
R设置为0，该第一MAC CE命令激活N1个TCI state，且每个激活的TCI state映射到DCI中TCI field的一个codepoint，共映射到N1个codepoint。
R设置为1，该第二MAC CE命令激活N2组TCI state中的TCI state，且每组激活的TCI state中包括M个TCI state，且每组激活的TCI state映射到DCI中TCI field的一个codepoint，共映射到N2个codepoint。
终端根据上述两个MAC CE命令，获知激活的N1个TCI state和N2个TCI state组中的TCI state，共同映射到DCI中TCI field的N1+N2个codepoint。这里的N1+N2不超过最大值N(如相关技术中N为8)。
本公开提出了新的MAC CE命令设计方法，可以支持DCI中TCI field的每个codepoint对应1个或多个TCI state，从而支持多TRP等通信场景中的TCI信息指示，该方法能够增加PDSCH波束信息指示的灵活性，兼容相关技术中的PDSCH波束信息指示方法，降低PDSCH波束信息的指示信令开销。
