其中,本申请的PRB捆绑尺寸(PRB bundling size)是指将一定数量的PRB捆绑在一起成为物理资源块绑定(PRB bundle),比如,PRB捆绑尺寸为2,则是指将2个PRB捆绑在一起成为一个物理资源块绑定。终端设备和/或网络设备可假定同一个预编码(precoding),应用于同一个物理资源块绑定中的PRB。
第一PDSCH的第一PRB捆绑尺寸是指在对PRB集合中的至少一个PRB进行捆绑时,一个物理资源块绑定中所包含的PRB数量,其中,该PRB集合中的至少一个PRB是用于传输该第一PDSCH的PRB。可选的,如果网络设备配置了用于传输MBS的第一频域资源或相关配置,该PRB集合中的PRB可以是所配置的第一频域资源中的PRB资源,比如网络设备配置了用于MBS的公共频域资源(Common Frequency Resource,CFR),该PRB集合中的PRB可以是CFR中的PRB资源,网络设备可以通过CFR配置信息配置该CFR,需要说明的是,网络设备配置的用于传输MBS的第一频域资源或相关配置可以不限制命 名为CFR,该CFR仅为举例,相应的用于配置CFR的配置信息也可以不限定为CFR配置信息。
在第一种可选的实施方式中,该第一PDSCH的第一PRB捆绑尺寸可以是预先设定的捆绑尺寸,比如,协议规定承载组播或者广播业务数据的group-common PDSCH的捆绑尺寸为2,可以理解的是,还可以是其他值,比如4或者宽带等。终端设备可以将预先设定的捆绑尺寸确定为第一PDSCH的第一PRB捆绑尺寸。
第二种可选的实施方式中,该第一PDSCH的第一PRB捆绑尺寸可以是根据网络设备发送的指示信息确定的,该指示信息用于直接或间接指示第一PRB捆绑尺寸,下面分别以方式一和方式二分别阐述:
方式一,该指示信息可以包括第一PDSCH的第一PRB捆绑尺寸,该第一PRB捆绑尺寸可以是2或4或宽带,其中,宽带是指将用于传输该第一PDSCH的所有PRB捆绑在一起成为物理资源块绑定。
可选的,包括第一PRB捆绑尺寸的指示信息可以是通过下行控制信息(Downlink Control Information,DCI)发送的,该DCI可以是由第一PDCCH承载,该第一PDCCH的CRC可以是由第一RNTI加扰的,该第一RNTI可以是网络设备分配给终端设备用于传输MBS的RNTI,可选的,该第一RNTI可以是G-RNTI或者G-CS-RNTI,本申请对于其具体命名不做限制,其中,第一PDSCH可以是由该第一PDCCH调度或激活的。可以理解的是,如果通过DCI指示第一PRB捆绑尺寸,则高层配置信息中PRB绑定类型应该被配置为动态绑定,该高层配置信息可以是CFR配置信息。可选的,用于承载PRB绑定类型的字段名称可以是prb-Bundling Type,当然还可以是其他命名,比如可以是prb-Bundling Type-r17,本申请不作限定。其中,该字段中具体内容动态绑定的命名可以是dynamicBundling,当然还可以是其他命名,比如可以是dynamicBundling-r17,本申请不作限定。
可选的,包括第一PRB捆绑尺寸的指示信息也可以是通过高层参数指示的,即该高层参数包括第一PRB捆绑尺寸,其中,该高层参数的命名不作限定,比如可以是bundling size或bundling size-r17等等。可以理解的是,如果是通过高层参数指示第一PRB捆绑尺寸,则高层配置信息中PRB绑定类型应该被配置为静态绑定,即用于承载PRB绑定类型的字段内容是静态绑定,静态绑定的命名不作限定,比如可以是staticBundling或者 staticBundling-r17。
示例性的,终端设备可以不期望PRB绑定类型被配置为动态绑定,即第一PRB捆绑尺寸由该高层参数进行指示,而不会通过动态的方式指示,比如不会通过DCI进行动态指示。
方式二,可以通过指示信息的状态值间接确定第一PDSCH的第一PRB捆绑尺寸,该指示信息的状态值也可以称为指示信息的取值。示例性的,该指示信息是某个字段中的至少一个比特,则该指示信息的状态值可以是该至少一个比特的取值。示例性的,该字段可以是DCI中的bundling size indicator字段,该字段中可以包括一个比特,指示信息的状态值可以是该比特的取值0或1,可选的,该DCI可以是通过第一PDCCH承载,该第一PDCCH的CRC是由第一RNTI加扰,其中,第一RNTI可以是网络设备分配给终端设备用于传输MBS的RNTI,可选的,该第一RNTI可以是G-RNTI或者G-CS-RNTI,本申请对于其具体命名不做限制,第一PDSCH可以是由该第一PDCCH调度或激活。
具体可选的,指示信息的不同状态值可以对应不同捆绑尺寸集合,该捆绑尺寸集合包括至少一个PRB捆绑尺寸,比如,如果指示信息的状态值为第一状态值,则对应第一捆绑尺寸集合,该第一捆绑尺寸集合可以包括一个或两个PRB捆绑尺寸。如果指示信息的状态值为第二状态值,则对应第二捆绑尺寸集合,该第二捆绑尺寸集合包括一个PRB捆绑尺寸,该第一捆绑尺寸集合和第二捆绑尺寸集合可以是高层配置的。其中,第一状态值可以是1,第二状态值可以是0,可以理解的是,如果指示信息包括多个比特,则该第一状态值可以是该多个比特的取值,比如,指示信息包括2个比特,第一状态值可以是01,第二状态值可以是11,对此本申请不作限定。
如果指示信息的状态值为第二状态值,则终端设备可以将第二捆绑尺寸集合中的捆绑尺寸确定为第一PRB捆绑尺寸。如果指示信息的状态值为第一状态值,且第一捆绑尺寸集合中包括一个PRB捆绑尺寸,则将该PRB捆绑尺寸确定为第一PRB捆绑尺寸;如果指示信息的状态值为第一状态值,且第一捆绑尺寸集合中包括两个PRB捆绑尺寸,则可以进一步判断PRB集合是否满足目标条件,该PRB集合中包括用于传输该第一PDSCH的至少一个PRB,如果PRB集合满足目标条件,则可以将第一捆绑尺寸集合中的预设捆绑尺寸确定为第一PRB捆绑尺寸,如果PRB集合不满足目标条件,则可以将第一捆绑尺寸集合中除预设捆绑尺寸外的一个捆绑尺寸确定为第一PRB捆绑尺寸,可选的,预设捆绑尺寸可 以是宽带。示例性的,第一捆绑尺寸集合可以是(2,宽带)或者(4,宽带),若PRB集合满足目标条件,第一PRB捆绑尺寸为宽带,若PRB集合不满足目标条件,则第一PRB捆绑尺寸为2或者4。
可选的,如果网络设备配置了用于传输MBS的第一频域资源,比如CFR,且PRB集合中的PRB在该第一频域资源中,上述目标条件可以包括:PRB集合中的所有PRB是连续的,且所述PRB集合中的PRB数量大于该第一PDSCH所在的第一频域资源的PRB总数量的一半。可选的,如果网络设备未配置第一频域资源,比如未配置CFR,上述目标条件可以包括:PRB集合中的所有PRB是连续的,且所述PRB集合中的PRB数量大于该第一PDSCH所在的宽带部分(Bandwidth Part,BWP)的PRB总数量的一半。
可选的,终端设备不期望第一捆绑尺寸集合中包括两个PRB捆绑尺寸,即第一捆绑尺寸集合中只包括一个PRB捆绑尺寸,而不会包括两个PRB捆绑尺寸,则在指示信息的状态值为第一状态值时,可以直接将第一捆绑尺寸集合中的PRB捆绑尺寸作为第一PRB捆绑尺寸,在指示信息的状态值为第二状态值时,可以直接将第二捆绑尺寸集合中的PRB捆绑尺寸作为第一PRB捆绑尺寸。
可以理解的是,上述方式二中通过指示信息间接指示第一PRB捆绑尺寸的设计中,高层配置信息的PRB绑定类型可以被配置为动态绑定,可选的,该高层配置信息可以是第一频域资源的配置信息,比如CFR配置信息。
可选地,如果网络设备没有配置第一频域资源,比如没有配置CFR,则第一PDSCH的第一PRB捆绑尺寸可以是预先设定的。
本申请实施例中,可以预先设定承载组播或广播业务数据的第一PDSCH的第一PRB捆绑尺寸,或者,可以通过网络设备的指示信息确定第一PDSCH的第一PRB捆绑尺寸,从而实现对承载组播或者广播业务数据的第一PDSCH的捆绑尺寸的确定。
