具体实施方式
为了便于理解，首先介绍本申请涉及的术语。
1、RV(Redundancy Version)，即冗余版本，用于实现增量冗余(Incremental redundancy，IR)混合自动重传请求(Hybrid Automatic Repeat reQuest，HARQ)传输，即将编码器生成的冗余比特分成若干组，每个RV定义一个传输开始点，首次传送和各次HARQ重传分别使用不同的RV，以实现冗余比特的逐步积累，完成增量冗余HARQ操作。
2、MCS(Modulation and Coding Scheme)，即调制与编码。MCS将所关注的影响通讯速率的因素作为表的列，将MCS索引作为行，形成一张速率表，每一个MCS索引其实对应了一组参数下的物理传输速率。
3、配置授权CG(configured grant，CG)，为半静态调度。半静态调度是指：基站通过RRC信令为终端配置一定的资源周期，并在每个周期内有相同的时频域资源用于数据传 输。该方式无需动态调度即可完成每次数据传输，可以降低调度信令开销，有利于降低传输时延。CG周期的可选范围包括：1、2、4、5、8、10、16、20、32、40、64、80、160、256、320、512、640、1024、1280、2560、5120个时隙(slot)。

下面结合附图对本申请所提供的一种确定TB的起始传输位置的方法及其装置进行详 细地介绍。
请参见图2，图2是本申请实施例提供的一种确定TB的起始传输位置的方法的流程示意图,由终端设备执行，如图2所示，该方法可以包括但不限于如下步骤：
S201，确定CG周期内用于传输同一TB块多个时隙的冗余版本RV序列。
为了避免通信系统中各种终端设备的传输之间发生冲突，终端设备可以接收网络设备对各种终端设备进行的传输的调度。在通信系统中，终端设备和网络设备可以在与信道的某些时间和频率资源相对应的时隙中进行通信，每个时隙可以包括多个符号周期并且与带宽相对应。每个时隙可以包括用于传输控制信息的控制信道和用于发送上行链路和/或下行链路数据的共享数据信道。网络设备可以在时隙的控制信道上发送调度授权，调度授权将时隙的一些或全部共享数据信道分配给终端设备。终端设备可以根据调度授权，使用共享数据信道来发送或接收数据。
当终端设备接收到网络设备发送的无线资源控制(Radio Resource Control，RRC)信令之后，可以从中解析出配置授权信息，根据该配置授权信息确定与配置授权相关的配置参数，并在终端设备处于多子带工作模式时使用配置参数。其中，配置授权信息中可以包括配置调度无线网络临时标识、下行配置授权配置和/或上行配置授权配置。配置调度无线网络临时标识是用于配置授权调度方式的标识，下行配置授权配置是用于配置采用配置授权方式的下行传输，上行配置授权配置是用于配置采用配置授权方式的上行传输。
配置授权(configured grant，CG)可以支持多时隙传输同一个TB块，即(TB processing over multipleslots，TBoMS)，也就是说将CG与多时隙传输相结合。终端设备可以接收网络设备发送的CG周期内用于传输同一TB块多个时隙的冗余版本(Redundancy Version，RV)序列，或者终端设备可以基于协议约定确定CG周期内用于传输同一TB块多个时隙的RV序列。
其中，RV序列可以是发送传输块的至少一个冗余版本的顺序。其中，TB是媒体介质访问控制(Medium Access Control，MAC)层交付到物理层待传的数据，终端设备对TB用多个时隙(slot)进行传输，每个slot只传输该TB的部分编码后数据。
S202，从RV序列对应多个时隙中，确定TB传输的至少一个起始传输位置。
在一个半静态传输周期内，RV序列对应多个时隙，多个时隙可以用相同的冗余版本，也可以用不同的冗余版本，可以基于网络设备的配置确定，也可以通过协议约定确定。示例性的，RV序列可以是{RV#0，RV#0，RV#0，RV#0}，或者{RV#0，RV#3，RV#0，RV#3}，或者{RV#0，RV#2，RV#3，RV#1}等。此处RV序列仅为示例，不能作为限制本申请的条件。
需要说明的是，在用多个时隙传输同一TB即TBoMS的场景下，每个时隙占用相同的时域资源，频域资源长度相等，频域资源位置可能相同或不同。其中，当开启跳频时，频域资源位置不同；当不开启跳频时，频域资源位置相同。
进一步的，当终端设备有数据产生时，为了能够及时进行数据传输，缩短传输时延，终端设备可以在非第1个时隙上开始进行数据重传，可以开启数据传输的时隙被成为初始传输位置，本申请实施例中可以从RV序列对应多个时隙中，确定TB传输的至少一个起始传输位置。在一些实现中，TB传输对应的起始传输位置可以为一个，也可以为多个；在一 些实现中，TB传输对应的起始传输位置可以为第一个，也可以为非第一个；在一些实现中，TB传输对应的起始传输位置可以为特定冗余版本包括的时隙，也可以为每个冗余版本包括的时隙。其中，当TB传输对应的起始传输位置为多个时，可以为前几个，也可以为后几个。
本申请实施例提出了一种确定TB的起始传输位置的方法，通过在配置授权CG支持TBoMS传输的场景下，确定CG周期内用于传输同一TB的多个时隙的冗余版本RV序列，从RV序列对应多个时隙中，确定TB传输的至少一个起始传输位置。本申请实施例，在用于传输同一TB的多个时隙中通过确定出TB传输的起始传输位置，可以将终端设备产生的数据及时传输，缩短了数据传输时延，提高了数据传输的可靠性。
图3是本申请实施例提供的一种确定TB的起始传输位置的方法的流程示意图,由终端设备执行，如图3所示，可以包括以下步骤：
S301，确定CG周期内用于传输同一TB的多个时隙的冗余版本RV序列。
关于步骤S301的实现方式，可采用本申请中各实施例中的实现方式，在此不再进行赘述。
S302，确定RV序列中的第一RV。
根据上述获取的RV序列，确定任一冗余版本为第一RV。示例性的，可将RV序列中RV#0的版本作为第一RV。可选地，也可将RV序列中其他冗余版本作为第一RV。
S303，从第一RV对应的每次TB传输使用多个时隙中，确定至少一个时隙作为起始传输位置。
作为一种可实现的方式，从RV序列中第一RV对应的每次TB传输使用多个时隙中，确定至少一个时隙作为起始传输位置。例如当确定RV#0为第一RV时，RV#0对应的可以为4个时隙，可以将RV#0的4个时隙中的第1个时隙确定为起始传输位置；或者，可以将RV#0的4个时隙中的前2个时隙确定为起始传输位置；或者，可以将RV#0的4个时隙中的4个时隙全部确定为起始传输位置。也就是说，在CG的TBoMS场景下，RV序列中每个RV#0对应的每个slot都可以作为起始传输时隙。
作为另一种可实现的方式，终端设备可以接收网络设备发送的指示信息，根据指示信息，确定第一RV中用作起始传输位置的一个时隙。举例说明，终端设备可以接收网络设备发送的指示信息，指示信息中可以直接指示用作起始传输位置的时隙，比如说指示信息可直接指示将RV序列中第一个RV#0对应的第一个时隙作为起始传输位置。
作为另一种可实现的方式，终端设备可以接收网络设备发送的指示信息，根据指示信息，确定第一RV中用作起始传输位置的多个时隙。举例说明，终端设备可以接收网络设备发送的指示信息，指示信息中可以直接指示用作起始传输位置的时隙，比如说指示信息可直接指示将RV序列中第一个RV#0对应的前三个时隙作为起始传输位置。

图4是本申请实施例提供的一种确定TB的起始传输位置的方法的流程示意图,由终端设备执行，如图4所示，当确定一个时隙作为起始传输位置时，从RV序列对应多个时隙中，确定TBoMS的一个起始传输位置，可以包括以下步骤：
S401，确定CG周期内用于传输同一TB的多个时隙的冗余版本RV序列。
关于步骤S401的实现方式，可采用本申请中各实施例中的实现方式，在此不再进行赘述。
S402，将RV序列中最后一个第一RV之外剩余的每个第一RV对应的第一个时隙，确定为起始传输位置，其中，RV序列仅包括第一RV。
示例性的，可将RV序列中RV#0的版本作为第一RV，响应于RV序列为仅包括第一RV，即RV序列＝{RV#0，RV#0，RV#0，RV#0}，即RV序列中所有的RV都为RV#0时，将RV序列中最后一个RV#0除外，剩余的每个RV#0对应的第一个时隙，确定为起始传输位置。即终端设备只可以在RV序列中前三个RV#0对应的第一个时隙上发起传输，而不能在RV序列中最后一个RV#0对应的所有时隙上发起传输，即RV序列中最后一个第一RV之外剩余的每个第一RV对应的第一个时隙，确定为起始传输位置。
S403，将至少一个第一RV对应的第一个时隙，确定为起始传输位置，RV序列包括至少一个第一RV和至少一个其他RV。
示例性的，可将RV序列中RV#0的版本作为第一RV，响应于获得的RV序列中不仅包括第一RV，还包括其他RV时，将每个第一RV对应的第一个时隙，确定为起始传输位置。其中，第一RV可以为一个或多个。
作为一种可实现的方式，若RV序列＝{RV#0，RV#3，RV#0，RV#3}时，即RV序列中不仅包括多个第一RV，还包括其他RV时，终端设备只可以在RV#0对应的第一个时隙上发起传输，即将RV#0对应的第一个时隙确定为起始传输位置。如图5所示，RV序列＝{RV#0，RV#3，RV#0，RV#3}，当在第一个RV#0对应的第二个时隙之前数据生成，将第二个RV#0对应的第一个时隙确定为起始传输位置，在第二个RV#0对应的第一个时隙开始数据传输。
作为另一种可实现的方式，若RV序列＝{RV#0，RV#2，RV#3，RV#1}时，即RV序列中不仅包括一个第一RV，还包括多个其他RV时，终端设备只可以在第一个RV#0对应的第一个时隙上发起传输，即将第一个RV#0对应的第一个时隙确定为起始传输位置。

图6是本申请实施例提供的一种确定TB的起始传输位置的方法的流程示意图,由终端设备执行，如图6所示，可以包括以下步骤：
S601，确定CG周期内用于传输同一TB的多个时隙的冗余版本RV序列。
关于步骤S601，上述实施例已做具体介绍，在此不再进行赘述。
S602，基于每次TB传输占用的时隙个数和/或调制与编码MCS参数，确定第一RV中用作起始传输位置的至少一个时隙。
作为一种可能的实现方式，根据调制与编码MCS参数，确定位置确定缩放因子，根据每次TB传输占用的时隙个数和位置确定缩放因子，确定用作起始传输位置的至少一个时隙。
调制与编码(Modulation and Coding Scheme，MCS)将所关注的影响通讯速率的因素作为表的列，将MCS索引作为行，形成一张速率表，每一个MCS索引其实对应了一组参数下的物理传输速率。
可选地，基于网络指示或者协议约定确定MCS参数，可以基于该MCS参数确定位置确定缩放因子，其中，将位置确定缩放因子记为1/P。其中，MCS参数与位置确定缩放因子负相关，即MCS参数越大，位置确定缩放因子越小。需要说明的是，若位置确定缩放因子记为P，此时MCS与位置确定缩放因子正相关。
在一些实现中，对MCS参数设定一个阈值，当MCS参数小于设定阈值时，则确定位置确定缩放因子为第一数值；在MCS参数大于或者等于设定阈值时，则确定位置确定缩放因子为第二数值。举例说明，基于公式：第1～N*1/P个时隙确定起始传输位置时，需要说明的是，若存在位置确定缩放因子为P，由于MCS与P正相关，此时第一数值小于第二数值。若存在位置确定缩放因子为1/P，由于MCS与1/P负相关，此时第一数值大于第二数值。
举例说明，在上述公式的基础上，位置确定缩放因子为P，设定阈值设置为k,第一数值设定为4，第二数值设定为8。当MCS参数小于k时，则确定位置确定缩放因子为4；在MCS参数大于或者等于k时，则确定位置确定缩放因子为8。
在一些实现中，对MCS参数设定一个阈值，当MCS参数小于设定阈值时，则确定位置确定缩放因子为第一数值；在MCS参数大于或者等于设定阈值时，则不启动位置确定缩放因子，直接将第一RV对应的第一个时隙作为起始传输位置。举例说明，可将设定阈值设置为k,第一数值设定为4。当MCS参数小于k时，则确定位置确定缩放因子为4；在MCS参数大于或者等于k时，则不启动位置确定缩放因子，直接将第一RV对应的第一个时隙作为起始传输位置。
在一些实现中，可以预先设置MCS参数与位置确定缩放因子之间的映射关系，在获取到MCS参数后，可以查询该映射关系，确定出位置确定缩放因子。
除上述根据MCS参数确定位置确定缩放因子之外，还可以直接基于网络指示或者协议约定确定位置确定缩放因子。比如说，协议可约定位置确定缩放因子为4。
获取每次TB传输占用的时隙个数，将每次TB传输占用的时隙个数记为N。根据每次TB传输占用的时隙个数和位置确定缩放因子，确定用作起始传输位置的一个时隙。举例说明，可设定起始传输位置为第1～N*1/P+1个时隙，若位置确定缩放因子P＝4，TBoMS一次传输占用的时隙个数N＝4时，起始传输位置为第1～2个时隙；若位置确定缩放因子P＝4，TB一次传输占用的时隙个数N＝8时，起始传输位置为第1～3个时隙。可以想到的是，当缩放因子P大于一次TB传输占用的slot个数N时，不启用缩放因子，直接将第一RV对应的第一个slot作为起始传输位置。
本申请实施例通过根据TB一次传输占用的时隙个数和MCS参数确定缩放因子，确定用作起始传输位置的至少一个时隙，可以将终端设备产生的数据及时传输，缩短了数据传输时延，增加了传输冗余，提高了数据传输的可靠性。

关于步骤S701～S702的实现方式，可采用本申请中各实施例中的实现方式，在此不再进行赘述。
S703，基于确定出的起始传输位置，在CG周期内对TB进行重复传输。
在配置授权CG支持TBoMS的场景下，还可以支持对TB的重复传输。本申请实施例中，在确定出TB传输的起始传输位置后，可以在CG周期内对该TB进行多次重复传输，例如，重传次数为8次，则CG周期内对该TB重复传输8次，每次传输时都是基于确定的起始传输位置开始传输。
本申请实施例，从RV序列对应的多个时隙中，确定出TB传输的起始传输位置，可以将终端设备产生的数据及时传输，缩短了数据传输时延，提高了数据传输的可靠性。并且基于重复传输机制，可以解决TB在传输中出现丢失的问题，提供数据传输的安全性和完整性。

关于步骤S801～S802的实现方式，可采用本申请中各实施例中的实现方式，在此不再进行赘述。
S803，确定待传输数据在第一RV中每个时隙上的编码数据。
示例性的，若TB传输每次占用第一RV中4个时隙，获取待传输数据在第一RV中每个时隙上的编码数据，也就是说，待传输数据的编码数据被分配到多个时隙上进行传输，即每个时隙对应待传输数据的部分编码数据。
S804，从起始传输位置所在时隙对应的编码数据开始，向网络设备发送剩余的编码数据。
图9为终端设备向网络设备发送编码数据的示意图，如图9所示，若在第一RV中第一个时隙中编码数据生成，终端设备可在第一RV中第二个时隙上开始进行传输，第二个时隙传输的也仍然是与其时隙位置对应的编码后数据。举例说明，若终端设备所生成的待传输数据在第一RV中每个时隙上的编码数据分别为12、34、56、78，终端设备在第一RV中第二个时隙上开始进行传输时，直接按照时隙顺序传输34、56、78，而不传输第一RV中第一个时隙对应的12。
本申请实施例为了避免给网络设备接收数据造成混淆，且缩短了数据传输时延，增加了传输冗余，提高了数据传输的可靠性。
在上述实施例的基础之上，本申请实施例中提供的确定TB的起始传输位置的方法还可以包括以下步骤：
终端设备还可以获取使能信令，通过该使能信令直接确定RV序列中第一RV中用作起始传输位置的时隙个数，其中，使能信令用于确定起始传输位置的时隙个数可以为1个或多个。比如说，使能信令可以设置1比特指示参数，当使能信令指示“1”时，表示可以使用多个时隙作为起始传输位置，当使能信令指示“0“时，表示只能使用一个时隙作为起始传输位置。

S1002，从RV序列对应多个时隙中，确定TB传输的至少一个起始传输位置。
在一个半静态传输周期内，RV序列对应多个时隙，多个时隙可以用相同的冗余版本，也可以用不同的冗余版本，可以基于网络设备的配置确定，也可以通过协议约定确定。示例性的，RV序列可以是{RV#0，RV#0，RV#0，RV#0}，或者{RV#0，RV#3，RV#0，RV#3}，或者{RV#0，RV#2，RV#3，RV#1}等。此处RV序列仅为示例，不能作为限制本申请的条件。
需要说明的是，在TBoMS用于盲重传的时隙上，每个时隙占用相同的时域资源，频域资源长度相等，频域资源位置可能相同或不同。其中，当开启跳频时，频域资源位置不同；当不开启跳频时，频域资源位置相同。
进一步的，网络设备需要接收终端设备所发送过来的数据，当终端设备有数据产生时，为了能够及时进行数据传输，缩短传输时延，终端设备可以在非第1个时隙上开始进行数据重传，可以开启数据传输的时隙被成为初始传输位置，本申请实施例中可以从RV序列对应多个时隙中，确定TB传输的至少一个起始传输位置。在一些实现中，TB传输对应的起始传输位置可以为一个，也可以为多个；在一些实现中，TB传输对应的起始传输位置可以为第一个，也可以为非第一个；在一些实现中，TB传输对应的起始传输位置可以为特定冗余版本包括的时隙，也可以为每个冗余版本包括的时隙。其中，当TB传输对应的起始传输位置为多个时，可以为前几个，也可以为后几个。
