Description

传输数据的方法、终端设备和网络设备 技术领域
本申请涉及通信领域，尤其涉及传输数据的方法、终端设备和网络设备。
背景技术
在LTE中，介质访问控制层(media access control，MAC)协议数据单元(protocol data unit，PDU)主要有MAC头(header)、0或多个MAC服务数据单元(service data unit，SDU)、0或多个MAC控制单元(control element，CE)以及可选的一些填充(padding)组成。
具体地，一个MAC PDU header由一个或者多个MAC PDU子头(subheader)组成，每一个subheader对应一个载荷(payload)，这个payload可以为一个MAC SDU、一个MAC CE或者一个padding。LTE中，MAC CE一般放置于所有MAC SDU的前面而在MAC subheader的后面。MAC subheader连接在一起置于MAC PDU的前面，且与后面的MAC CE、MAC SDU和padding一一对应。
而在NR中，MAC PDU结构(format)将与LTE中的MAC PDU format有如下几点不同：
第一，NR上行MAC PDU与下行MAC PDU的format不同，而LTE上下行MAC PDU的format是统一的；
第二，NR MAC PDU的subheader与其对应的paylaod放置在一起，且MAC subheader置于对应的payload前方，而不是像LTE一样统一置于MAC PDU的前方；
第三，NR下行MAC PDU的MAC CE连同其对应的MAC subheader置于MAC PDU的前方，这样的设计主要是便于UE侧能够快速获得MAC CE中的控制信息；
第四，NR上行MAC PDU的MAC CE连同其对应的MAC subheader置于所有MAC SDU的后面，这样的设计主要是考虑到有些实时MAC CE，比如缓存状态报告(buffer status report，BSR)，需要等到MAC SDU确定好之后才能生成。
由于，NR系统中上行MAC CE置于MAC PDU中的MAC SDU的后方， 则网络设备在接收到终点设备发送的MAC PDU时，需要解调完所有MAC SDU之后才能获得相应的MAC CE控制信息，导致网络设备无法尽快获取终端设备的MAC控制信息。
发明内容
本申请提供了一种传输数据的方法、终端设备和网络设备，能够使得网络设备可以快速确定MAC CE，提高效率。。
第一方面，提供了一种传输数据的方法，该方法包括：确定位置信息，该位置信息用于指示第一MAC PDU包括的n个MAC CE的位置，n为正整数；向网络设备发送该第一MAC PDU，该第一MAC PDU包括该位置信息。
因此，本申请实施例的传输数据的方法，终端设备向网络设备发送包括位置信息的MAC PDU，网络设备根据该位置信息确定该MAC PDU中包括的n个MAC CE的位置，使得网络设备可以快速获取该n个MAC CE中的控制信息，提高效率。
结合第一方面，在第一方面的一种实现方式中，该第一MAC PDU包括与该n个MAC CE一一对应的n个subheader，该n个MAC CE中第i个MAC CE与对应的第i个subheader相邻且位于该第i个subheader之后，i为小于或者等于n的正整数，该第一MAC PDU包括m个MAC SDU以及与该m个MAC SDU一一对应的m个subheader，该m个MAC SDU中第j个MAC SDU与对应的第j个subheader相邻且位于该第j个subheader之后，该m个MAC SDU和该m个subheader位于该n个MAC CE和该n个subheader之前，m为正整数，j为小于或者等于m的正整数，该第一MAC PDU包括padding以及与该padding对应的subheader，该padding和该padding对应的subheader相邻，该padding和该padding对应的subheader位于该m个MAC SDU和该m个subheader之后。
应理解，考虑到有些实时MAC CE，比如BSR，需要等到MAC SDU确定好之后才能生成，因此对于上行MAC PDU，即该第一MAC PDU包括的m个MAC SDU，可以位于该第一MAC PDU的前面。
可选地，该n个MAC CE和该n个subheader可以位于该padding和该padding对应的subheader之前或者之后。
可选地，该padding位于该padding对应的subheader之前或者之后。
结合第一方面及其上述实现方式，在第一方面的另一种实现方式中，该位置信息包括特定比特位与该n个MAC CE中第一个MAC CE对应的subheader的第一个比特位之间的比特数。
结合第一方面及其上述实现方式，在第一方面的另一种实现方式中，该特定比特位为该第一MAC PDU的第一个比特位。
对应的，该位置信息包括该第一个比特位到n个MAC CE中第一个MAC CE对应的subheader的第一个比特位之间的比特数。例如，当该位置信息在该第一MAC PDU的最前端时，则位置信息包括位置信息的长度、m个MAC SDU以及对应的m个subheader的总长度，即总比特数。
结合第一方面及其上述实现方式，在第一方面的另一种实现方式中，该特定比特位为该m个MAC SDU中的第一个MAC SDU对应的subheader的第一个比特位。

对应的，当该n个MAC CE和对应的n个subheader位于该m个MAC SDU和该m个subheader之后、该padding和该padding对应的subheader之前，该padding位于该padding对应的subheader之后时，该位置信息包括n个MAC CE、该n个subheader、该padding和该padding对应的subheader的总长度。
当该n个MAC CE和对应的n个subheader位于该m个MAC SDU和该m个subheader之后，也位于该padding和该padding对应的subheader之后，且该padding位于该padding对应的subheader之后时，位置信息包括该n个MAC CE和对应的n个subheader的总长度。

应理解，由于此时第一MAC PDU的总长度较大或该该第一MAC PDU包括的m个MAC SDU的总长度较大，则该位置信息可以设置为从该第一MAC PDU的后面的比特位向前查找n个MAC CE的位置。
应理解，该第一预设值和第二预设值可以根据实际情况进行设置。
结合第一方面及其上述实现方式，在第一方面的另一种实现方式中，该确定生效指示信息，包括：在该第一MAC PDU的总长度小于该第一预设值或者该第一MAC PDU包括的m个MAC SDU的总长度小于该第二预设值时，确定该生效指示信息用于指示该网络设备不执行根据该位置信息确定该n个MAC CE的位置。

图1示出了根据本申请实施例的传输数据的方法100的示意性流程图，该方法100可以由上述的终端设备执行。如图1所示，该方法100包括：
S110，确定位置信息，该位置信息用于指示第一MAC PDU包括的n个MAC CE的位置，n为正整数；

具体地，终端设备向网络设备发送第一MAC PDU，该第一MAC PDU中可以包括n个MAC CE，该第一MAC PDU中还包括位置信息，该位置信息用于指示该n个MAC CE的位置，网络设备接收该第一MAC PDU，根据该MAC PDU中的位置信息，确定该第一MAC PDU中n个MAC CE的位置，进而获得该n个MAC CE中的控制信息。

在本申请实施例中，终端设备向网络设备发送的第一MAC PDU可以包括n个MAC CE，该n个MAC CE与n个subheader一一对应，其中，n个MAC CE中的第i个MAC CE与对应的第i个subheader相邻且位于该第i个subheader之后，i为小于或者等于n的正整数。该第一MAC PDU还包括m个MAC SDU，该m个MAC SDU与m个subheader一一对应，其中，m个MAC SDU中的第j个MAC SDU与对应的第j个subheader相邻且位于该第j个subheader之后，m为正整数，j为小于或者等于m的正整数。该第一MAC PDU还包括padding以及该padding对应的subheader，该padding与对应的subheader相邻，该padding可以位于对应的subheader之后，也可以位于对应的subheader之前。
应理解，考虑到有些实时MAC CE，比如BSR，需要等到MAC SDU确定好之后才能生成，因此对于上行MAC PDU，即该第一MAC PDU包括的m个MAC SDU，可以位于该第一MAC PDU的前面，具体地，该m个MAC SDU以及对应的m个subheader均位于n个MAC CE以及对应的n个subheader之前，也位于padding和该padding对应的subheader之前，而该n个MAC CE以及对应的n个subheader可以位于该padding和该padding对应的subheader之前，或者，也可以位于该padding和该padding对应的subheader之后，本申请实施例并不限于此。
在S 110中，终端设备根据第一MAC PDU中的n个MAC CE的位置生成位置信息，通过该位置信息指示该n个MAC CE在该第一MAC PDU中 的位置。可选的，该位置信息可以位于该第一MAC PDU的最前端，例如如图2或图3所示，或者，该位置信息也可以位于该第一MAC PDU的最后端，例如如图4或图5所示，本申请实施例并不限于此。
在S120中，终端设备向网络设备发送包括该位置信息的第一MAC PDU，使得该网络设备可以根据该第一MAC PDU中的位置信息，确定第一MAC PDU中的n个MAC CE的位置。

为了便于描述，下文中假设该第一MAC PDU包括2个MAC SDU，分别为MAC SDU 1和MAC SDU 2，该第一MAC PDU还包括2个MAC CE，分别为MAC CE 1和MAC CE 2，该第一MAC PDU还包括padding，另外，该第一MAC PDU还包括与各个payload对应的subheader，但本申请实施例并不限于此。

再例如，如图4所示，该特定比特位可以为该第一MAC PDU的最后一个比特位，即该位置信息的最后一个比特位，则该位置信息可以包括该位置信息的长度和第二长度。对应的，网络设备根据该位置信息中的比特数，从该第一MAC PDU的最后一个比特位开始向前计数，可以确定该第一MAC PDU包括的n个MAC CE中第一个MAC CE对应的subheader的第一个比特位，进而获取该n个MAC CE。
再例如，如图4所示，该特定比特位可以为该第一MAC PDU包括的padding的最后一个比特位，则该位置信息可以包括第二长度。对应的，网络设备根据该位置信息中的比特数，即第二长度，从该第一MAC PDU的padding的最后一个比特位开始向前计数，可以确定该第一MAC PDU包括的n个MAC CE中第一个MAC CE对应的subheader的第一个比特位，进而获取该n个MAC CE。
可选的，作为一个实施例，该第一MAC PDU包括的n个MAC CE以 及对应的n个subheader还可以位于该第一MAC PDU的后面，即位于m个MAC SDU和对应的m个subheader、padding以及padding对应的subheader的后面。例如，图5示出了根据本申请实施例的第一MAC PDU的示意图，即该第一MAC PDU中每个字段的排列顺序可以如图5所示。
具体地，根据图5中多个MAC CE中第一个MAC CE对应的subheader位置，即与MAC CE 1相邻且位于该MAC CE之前的subheader的位置，可以将该第一MAC PDU看作两部分，其中，第一部分为该第一MAC PDU包括的m个MAC SDU和对应的m个subheader，以及padding和padding对应的subheader，即MAC SDU 1、MAC SDU 2、对应的2个subheader、padding以及padding对应的subheader，且该第一部分的总比特数对应如图5所示第一长度；第二部分为该第一MAC PDU包括的n个MAC CE以及对应的n个subheader，即MAC CE 1、MAC CE 2和对应的2个subheader，且该第二部分的总比特数对应如图5所示第二长度。
在本申请实施例中，位置信息可以包括特定比特位与该n个MAC CE中第一个MAC CE对应的subheader的第一个比特数之间的比特数。例如，如图5所示，该特定比特位可以为该第一MAC PDU的第一个比特位，即该第一MAC PDU的第一个MAC SDU对应的subheader的第一个比特位，则该位置信息可以包括第一长度。对应的，网络设备根据该位置信息中的比特数，即第一长度，从该第一MAC PDU的第一个比特位，即第一个MAC SDU对应的subheader的第一个比特位开始向后计数，可以确定该第一MAC PDU包括的n个MAC CE中第一个MAC CE对应的subheader的第一个比特位，进而获取该n个MAC CE。
再例如，如图5所示，该特定比特位可以为该位置信息的最后一个比特位，则该位置信息可以包括该位置信息的长度和第二长度。对应的，网络设备根据该位置信息中的比特数，从该第一MAC PDU的最后一个比特位开始向前计数，可以确定该第一MAC PDU包括的n个MAC CE中第一个MAC CE对应的subheader的第一个比特位，进而获取该n个MAC CE。
再例如，如图5所示，该特定比特位可以为该第一MAC PDU的MAC CE2的最后一个比特位，则该位置信息可以包括第二长度。对应的，网络设备根据该位置信息中的比特数，即第二长度，从该第一MAC PDU中的MAC CE2的最后一个比特位开始向前计数，可以确定该第一MAC PDU包括的n个 MAC CE中第一个MAC CE对应的subheader的第一个比特位，进而获取该n个MAC CE。
可选的，作为一个实施例，该位置信息还可以位于padding对应的subheader中，例如可以复用该padding对应的subheader中的比特位。具体地，当该第一MAC PDU包括的n个MAC CE以及对应的n个subheader位于m个MAC SDU和对应的m个subheader、padding以及padding对应的subheader之间时，即图6示出了根据本申请实施例的第一MAC PDU的示意图，即该第一MAC PDU中每个字段的排列顺序可以如图6所示，此时padding位于对应的subheader之前，且该padding对应的subheader中包括位置信息。
具体地，与padding对应的subheader可以用于指示该padding的长度，而当该subheader中包括位置信息时，该位置信息可以包括特定比特位与该n个MAC CE中第一个MAC CE对应的subheader的第一个比特数之间的比特数，则该padding对应的subheader可以用于指示从第一个MAC CE对应的subheader的第一个比特位到padding的最后一个比特位之间的比特数。则网络设备可以根据该padding对应的subheader中包括的比特数，从padding的最后一个比特位向前计数，可以确定该第一MAC PDU包括的n个MAC CE中第一个MAC CE对应的subheader的第一个比特位，进而获取该n个MAC CE。
应理解，本申请实施例中的位置信息可以为一个独立的域，即例如如2至图5所示，可以位于第一MAC PDU的最前面或者最后面，其大小可以为至少为1字节(byte)，例如如图7所示，该位置信息可以为1byte，即8比特(bit)，或者该位置信息也可以为2byte，本申请实施例并不限于此。
可选的，该位置信息也可以复用第一MAC PDU中的padding对应的subheader中的某个字段，例如如图6所示，padding对应的subheader包括该位置信息，该位置信息可以复用该subheader中表示长度(length)的L域，则该位置信息的大小等于L域的大小。
具体地，图8示出了根据本申请实施例的padding对应的subheader的示意图，如图8所示，该subheader可以包括R域，该R域为预留比特位(reserve bit)；该subheader还包括F域，该F域用于指示该subheader包括的L域的大小，例如图8中所示，该L域的大小可以为8bit，则F域指示该L域的大 小为8bit；该subheader还包括逻辑信道标识(logical channel identify，LCID)域，该LCID用于指示该subheader为padding对应的subheader；该subheader还包括L域，该L域用于承载位置信息，例如图8所示，该L域大小可以为lbyte，但本申请实施例并不限于此。
可选的，该方法100还可以包括：终端设备确定生效指示信息，该生效指示信息用于指示网络设备是否需要根据该位置信息确定该第一MAC PDU中包括的n个MAC CE的位置。
例如，当该第一MAC PDU的总长度大于或者等于第一预设值时，或者该第一MAC PDU包括的m个MAC SDU的总长度大于或者等于第二预设值时，终端设备可以将生效指示信息设置为用于指示该网络设备需要根据该位置信息确定该第一MAC PDU中包括的n个MAC CE的位置，例如，该生效指示信息可以设置为一个比特，用“1”表示该网络设备需要根据该位置信息确定该第一MAC PDU中包括的n个MAC CE的位置，则网络设备可以根据该生效指示信息，确定是否根据该位置信息确定该第一MAC PDU中包括的n个MAC CE的位置。
另外，由于此时第一MAC PDU的总长度较大或该该第一MAC PDU包括的m个MAC SDU的总长度较大，则该位置信息可以设置为从该第一MAC PDU的后面的比特位向前查找n个MAC CE的位置，但本申请实施例并不限于此。
对应的，当该第一MAC PDU的总长度小于第一预设值时，或者该第一MAC PDU包括的m个MAC SDU的总长度小于第二预设值时，终端设备可以将生效指示信息设置为用于指示该网络设备不需要根据该位置信息确定该第一MAC PDU中包括的n个MAC CE的位置，例如，该生效指示信息可以设置为一个比特，用“0”表示该网络设备不需要根据该位置信息确定该第一MAC PDU中包括的n个MAC CE的位置，则网络设备可以根据该生效指示信息，确定是否根据该位置信息确定该第一MAC PDU中包括的n个MAC CE的位置。
应理解，该第一预设值和第二预设值可以根据实际情况进行设置，本申请实施例并不限于此。
再例如，对于其他网络设备需要确定MAC CE位置的特殊情况，终端设备也可以将生效指示信息设置为用于指示该网络设备需要根据该位置信 息确定该第一MAC PDU中包括的n个MAC CE的位置，但本申请实施例并不限于此。
应理解，该第一MAC PDU中的位置信息和生效指示信息可以设置为连续字段，共同占用至少1byte，例如，可以占用1byte或者2byte。具体地，如图9所示，该位置信息和生效指示信息一共1byte，其中，生效指示信息占用1比特(bit)，例如，可以将该比特位设置为“1”或者“0”；而位置信息占用其余比特，即7bit。
可选地，对于padding对应的subheader包括位置信息的情况，该subheader也可以包括该生效指示信息，即生效指示信息和位置信息共同复用padding对应的subheader中的L域。
可选的，作为一个实施例，该方法100还可以包括：该终端设备还可以向网络设备发送第二MAC PDU，该第二MAC PDU可以包括指示信息，该指示信息用于指示第二MAC PDU中不包括MAC CE。
具体地，当MAC PDU中包括MAC CE时，则终端设备可以通过位置信息，以及生效指示信息，指示网络设备该MAC PDU中包括MAC CE，并指示该MAC CE的位置，即上述终端设备向网络设备发送的第一MAC PDU中可以包括位置信息，该位置信息用于指示该第一MAC PDU中包括的n个MAC CE的位置。当该MAC PDU中不包括MAC CE时，则终端设备可以通过指示信息，指示该网络设备该MAC PDU中不包括MAC CE。
应理解，该第二MAC PDU中包括的指示信息类似第一MAC PDU中包括的位置信息，例如该指示信息的位置以及大小，可以与位置信息一致，即当MAC PDU中包括MAC CE时，该MAC PDU中包括位置信息；当MAC PDU中不包括MAC CE时，该MAC PDU中包括指示信息，即该指示信息可以看作该位置信息为特殊值的情况，在此不再赘述。
例如如图7所示，该指示信息可以为1byte，通过该1byte表示的特殊值指示该MAC PDU中不包括MAC CE，但本申请实施例并不限于此。
