技术领域
本公开涉及通信技术领域，尤其涉及一种DMRS资源确定方法和通信设备。
背景技术
一些通信系统中支持码分复用(Code Division Multiplexing，CDM)技术在CDM技术中每个CDM组内可以通过正交码(Orthogonal Cover Code，OCC)区分多个解调参考信号(Demodulation Reference Signal，DMRS)天线端口。进一步的，一些通信系统中还支持多点协作传输技术。例如：在第五代(5 th generation，5G)通信系统中会引入多传输接收点(Transmission Reception Point，TRP)或者多面板传输技术。由于相关技术中的网络侧只能向终端指示一组DMRS天线端口，从而在多个TRP或者面板进行传输时，只能约束这多个传输接收点(Transmission Reception Point，TRP)或者面板使用相同的层数进行传输，即只支持一种传输配置指示状态(Transmission Configuration Indication state，TCI state)传输，进而导致通信系统的频带利用率比较低。

具体实施方式
为使本公开要解决的技术问题、技术方案和优点更加清楚，下面将结合附图及具体实施例进行详细描述。
参见图1，图1是本公开实施例可应用的网络结构示意图，如图1所示，包括终端11和网络侧设备12，其中，终端11可以是用户终端(User Equipment，UE)或者其他终端设备，例如：手机、平板电脑(Tablet Personal Computer)、膝上型电脑(Laptop Computer)、个人数字助理(Personal Digital Assistant，PDA)、移动上网装置(Mobile Internet Device，MID)、可穿戴式设备(Wearable Device)、机器人、车辆等终端侧设备，需要说明的是，在本公开实施例中并不限定终端的具体类型。网络侧设备12可以是基站，例如：宏站、长期演进(Long Term Evolution，LTE)演进型基站(evolved node base station，eNB)、5G新空口(New Radio，NR)基站(node base station，NB)等；网络侧设备也可以是小站，如低功率节点(Low Power Node，LPN)、微微基站(pico)、毫微微基站(femto)等小站，或者网络侧设备可以是接入点(Access Point，AP)；网络侧设备也可以是中央单元(Central Unit，CU)与其管理和控制的多个传输接收点(Transmission Reception Point，TRP)共同组成的网络节点。需要说明的是，在本公开实施例中并不限定网络侧设备的具体类型。
需要说明的是，本公开实施例可以应用于支持多点协作传输技术的通信系统，例如：5G通信系统，当然，并不限定应用于5G通信系统，例如：还可以应用于后续演进的通信系统，或者第四代(4 th generation，4G)通信系统等。
请参见图2，图2是本公开实施例提供的一种DMRS资源确定方法的流程图，如图2所示，包括以下步骤：
步骤201、传输控制信息，所述控制信息包括第一值，所述第一值用于指示至少两个CDM组；
步骤202、在所述至少两个CDM组中，确定多个TCI state中各TCI state对应的CDM组，其中，在使用第一TCI state进行数据传输时，需要空开所述第一TCI state对应的CDM组的DMRS资源，所述第一TCI state为所述多个TCI state中的任一TCI state，且所述各TCI state与CDM组具有对应关系。
需要说明的是，本公开实施例提供的上述DMRS资源确定方法可以应用于通信设备，该通信设备可以是终端或者网络侧设备。
其中，上述控制信息可以是网络侧设备发送给终端的，也就是说，在上述通信设备为终端的情况下，步骤201是接收到上述控制信息，在上述通信设备为网络侧设备的情况下，步骤201是发送上述控制信息。
上述多个TCI state可以是网络侧设备配置给终端的，当然，对此不作限定，例如：也可以是终端请求的，或者终端自行配置的。
上述各TCI state与CDM组具有对应关系可以是预先配置的，例如：固定的对应关系，或者动态指示的，且一个TCI state对应至少一个CDM组。
另外，上述第一值可以是天线端口配置(例如：DMRS table)中的一个值(value)，在该天线端口配置中第一值可以指示DMRS端口(DMRS port(s))，以及指示至少两个CDM组，其中，指示的DMRS端口至少属于两个CDM组，且上述第一值还适用于使用至少两个TCI state的情况，且每个TCI state至少对应于一个上述CDM组，且每个TCI state对应的CDM组之间没有重复。也就是说，天线端口配置(例如：DMRS table)中至少包含支持以下特征的value：
其分配的DMRS端口至少属于两个CDM组；
适用于使用至少两个TCI state的情况；
每个TCI state至少对应于一个上述CDM组，且每个TCI state对应的CDM组之间没有重复。
需要说明的是，上述天线端口配置可以是网络侧设备预先配置给终端的，或者可以是协议约定的，且上述天线端口配置可以是DMRS表(DMRS table)。
另外，本公开实施例中，CDM组与天线端口的对应关系可以是预先配置 的，或者灵活指示的，对此不作限定。从而在确定各TCI state对应的CDM组后，可以确定各TCI state对应的天线端口。
另外，上述在使用第一TCI state进行数据传输时，需要空开所述第一TCI state对应的CDM组的DMRS资源可以是，在使用各TCI state进行数据传输时，需要空开各自对应的CDM组的DMRS资源(即不使用这部分资源进行数据传输)。例如：使用TCI state进行数据传输时，进行速率匹配过程中需要空开该TCI state的CDM组的DMRS资源。需要说明的是，本公开实施例中，并不限定CDM组与DMRS资源的对应关系，例如：CDM组与DMRS资源的对应关系可以是协议中已定义的对应关系，或者后续协议新定义的对应关系，或者网络侧指示的对应关系等。另外，CDM组的DMRS资源可以是CDM组对应的天线端口。
本公开实施例中，通过上述步骤可以实现各TCI state确定对应的CDM组，且在使用各TCI state进行数据传输时，需要空开各自对应的CDM组的DMRS资源，从而支持多TCI state传输，也就是说，不需要约束多个TRP或者面板使用相同的层数进行传输，允许多个TRP或者面板使用不同的层数进行传输，这样不会对能够使用的总层数带来限制，进而提高通信系统的频带利用率。
进一步的，在确定各天线端口集合的天线端口之后，还可以使用各TCI state进行数据传输。
作为一种可选的实施方式，所述多个TCI state对应的频域资源不重叠；或者
所述多个TCI state对应的时域资源不重叠；或者
所述多个TCI state对应的时域和频域资源均不重叠。
例如：在时分复用(Time Division Multiplexing，TDM)的传输方案中，多个TCI state对应的时域资源不重叠，在频分复用(Frequency Division Multiplexing，FDM)的传输方案中，多个TCI state对应的频域资源不重叠，在TDM+FDM的传输方案中，多个TCI state对应的时域和频域资源不重叠。
该实施方式中，由于上述多个TCI state对应的资源不重叠，从而在使用上述多个TCI state进行传输时，使得传输性能会更佳。例如：如果控制信息 指示了DMRS table中的上述第一值，而且不同的TCI state对应的时域或频域或时域/频域资源不重叠时，可以采用上述方式确定每个TCI state对应的CDM组，以及使用每个TCI state进行传输时需要空开(进行速率匹配)的DMRS资源。
当然，对此不作限定，例如：网络侧指定了特定的传输方案时，如TDM、FDM或者TDM+FDM传输方案时，一样可以采用上述方式确定每个TCI state对应的CDM组，以及使用每个TCI state进行传输时需要空开(进行速率匹配)的DMRS资源。
作为一种可选的实施方式，在所述多个TCI state中不同的TCI state对应的CDM组不同。
该实施方式中，由于不同的TCI state对应的CDM组不同，从而可以使得传输不会冲突，以提高传输性能。
可选的，所述各TCI state与CDM组具有固定的对应关系；或者
所述各TCI state与CDM组具有的对应关系为所述第一值动态指示的对应关系。
例如：在固定关系中，TCI state 0映射到CDM组(CDM group)0，TCI state 1映射到其余的CDM group；
在动态关系中，CDM组与TCI state的对应关系取决于DMRS table中的value，例如对于value A，TCI state 0映射到CDM group 0，TCI state 1映射到其余的CDM group；对于value B，TCI state 0映射到CDM group 0之外的CDM group，TCI state 1映射到CDM group 0。
通过上述固定关系可以节约天线端口配置的开销，而通过上述第一信息域动态指示的对应关系可以提高天线端口配置的灵活性。
作为一种可选的实施方式，所述第一值指示所述至少两个CDM组为不包含数据的CDM组。
例如：在DMRS table中的上述第一值指示至少两个不包含数据的CDM group。
由于第一值指示所述至少两个CDM组为不包含数据的CDM组，从而可以支持至少两个TCI state的传输，以提高资源利用率。例如：TCI state 0对 应CDM group 0，TCI state 1对应CDM group1，从而使用CDM group 0传输TCI state 0的DMRS，并在使用TCI state0进行数据传输时只需要空开CDM group 0；而使用CDM group 1传输TCI state 1的DMRS，从而在使用TCI state1进行数据传输时只需要空开CDM group1，从而支持TCI state 0和TCI state 1。
作为一种可选的实施方式，在所述第一TCI state对应的资源中，不包含数据的CDM组为所述第一TCI state对应的CDM组。
由于在所述第一TCI state对应的资源中，不包含数据的CDM组为所述第一TCI state对应的CDM组，这样可以实现对于每个TCI state对应的时域/频域/时频域资源，不包含数据的CDM组＝该TCI state所对应的CDM组，从而避免针对任一TCI state不包含数据的CDM组为第一值指示的至少两个不包含数据的CDM组(也就是说，此时DMRS table中，不包含数据的CDM组数的指示信息无效)，以将第一值指示的至少两个不包含数据的CDM组分配到多个TCI state，以提高资源利用率。例如：在使用TCI state1进行传输时，只需要空开CDM组1，而CDM组0可以进行传输；而在使用TCI state0进行传输时，只需要空开CDM组0，而CDM组1可以进行传输。
需要说明的是，本公开实施例中，在使用TCI state进行数据传输时，需要空开的DMRS资源并不限定只有该TCI state对应的CDM组的DMRS资源，例如：可能还有其他控制信息用于指示进行传输时需要空开(进行速率匹配)的DMRS资源。
作为一种可选的实施方式，所述在所述至少两个CDM组中，确定多个TCI state中各TCI state对应的CDM组，包括：
确定所述第一值在天线端口配置所指示的多个TCI state中各TCI state对应的CDM组；
其中，所述天线端口配置用于配置如下内容：
所述第一值对应的至少两个不包含数据的CDM组，所述第一值对应的TCI state与CDM组的对应关系，所述第一值对应的在使用TCI state进行数据传输时需要空开的CDM组。
其中，上述天线端口配置可以是网络侧设备预先配置给终端的，或者可以是协议约定的，且上述天线端口配置可以是DMRS表(DMRS table)，或 者其他形式的天线端口配置。该天线端口配置中至少部分值用于指示至少两个不包含数据的CDM组，以及对应的TCI state与CDM组的对应关系，以及对应的在使用TCI state进行数据传输时需要空开的CDM组。
需要说明的是，由于所述第一值对应的TCI state与CDM组的对应关系可以是固定关系，使用TCI state进行数据传输时需要空开CDM组为该TCI state对应的CDM组，从而在上述天线端口配置也可以不用于配置如下内容：
所述第一值对应的TCI state与CDM组的对应关系，所述第一值对应的在使用TCI state进行数据传输时需要空开的CDM组。
下面天线端口配置为DMRS table，CDM组为DMRS CDM为例，通过表1至表8进行举例说明，其中，表1至表8给出了部分value用于本公开实施例确定DMRS资源，例如：对应行包括TCI state与端口集合的对应以及使用每个TCI state进行传输时需要空开(进行速率匹配)的DMRS资源的value。需要说明的是，表中只给出了部分value进行示意，具体可根据本公开实施例定义其他value。
