当然，其他的需要通过卫星进行通信的场景均可以采用本公开提供的方案。
下面先从卫星侧介绍一下本公开提供的用于混合自动重传请求HARQ传输的方法。
本公开实施例提供了一种用于混合自动重传请求HARQ传输的方法，可以用于卫星，参照图2所示，图2是根据一实施例示出的一种用于混合自动重传请求HARQ传输的方法流程图，该方法可以包括以下步骤：
在步骤101中，确定终端支持的目标HARQ进程数。
在本公开实施例中，终端支持的目标HARQ进程数是该终端可以并发处理的最多的HARQ进程的数目。
在步骤102中，响应于所述目标HARQ进程数大于目标数目，确定目标加扰序列。
在本公开实施例中，目标数目是下行控制信息DCI中用于指示HARQ进程数的目标信息域所指示的最大值。其中，比如目标信息域占用的比特长度为4比特时，可以指示的HARQ进程数的最大值为16，即目标数目为16。比如目标信息域占用的比特长度为5比特时，可以指示的HARQ进程数的最大值为32，即目标数目为32。
在卫星确定终端支持的目标HARQ进程数超过了上述的目标数目的情况下，可以确定目标加扰序列。
在步骤103中，将通过所述目标加扰序列加扰后的DCI，发送给所述终端。
终端在接收到加扰后的DCI之后，在确定目标加扰序列属于多个预设加扰序列中的一个的情况下，会基于该DCI和目标加扰序列，确定终端支 持的目标HARQ进程数。
上述实施例中，可以在不增加DCI中用于指示HARQ进程数的目标信息域所占用的比特长度的情况下，将终端支持的超过目标数目的目标HARQ进程数告知终端。
在一可选实施例中，步骤101可以包括：
基于所述终端上报的终端能力信息，确定所述终端支持的所述目标HARQ进程数。
在本公开实施例中，终端能力信息是与终端支持的HARQ进程相关的信息，包括但不限于buffer size(缓存区大小)等信息。
卫星基于所述终端能力信息，确定所述终端支持的所述目标HARQ进程数。
上述实施例中，卫星可以基于终端上报的终端能力信息，来确定终端支持的目标HARQ进程数。实现简便，可用性高。
在一可选实施例中，在终端曾经接入该卫星，且卫星中存在该终端支持的目标HARQ进程数的历史记录的情况下，如果终端再次接入该卫星，卫星可以根据历史记录，直接确定该终端支持的目标HARQ进程数。
在一可选实施例中，参照图3所示，图3是根据图2所示的实施例示出的另一种用于混合自动重传请求HARQ传输的方法流程图，上述方法还包括：
在步骤104中，确定多个预设加扰序列与HARQ进程数的范围值的关联关系。
在本公开实施例中，多个预设加扰序列与HARQ进程数的范围值的关联关系可以用两者之间的对应关系表示，例如预设加扰序列1对应的HARQ进程数的范围值是1至16，预设加扰序列2对应的HARQ进程数的范围值是17至32，例如图4所示，以此类推。
上述实施例中，卫星可以确定多个预设加扰序列与HARQ进程数的范围值的关联关系，以便后续确定目标信息域对应的比特值，可用性高。
在一可选实施例中，参照图5所示，图5是根据图2所示的实施例示出的另一种用于混合自动重传请求HARQ传输的方法流程图，上述方法还包括：
在步骤105中，将所述多个预设加扰序列与HARQ进程数的范围值的关联关系发送给所述终端。
在本公开实施例中，卫星可以通过信令将上述关联关系发送给终端。其中，上述信令包括但不限于MAC(Media Access Control，媒体访问控制)信令、RRC(Radio Resource Control，无线资源控制)信令、系统消息等。
上述实施例中，可以由卫星通过信令将多个预设加扰序列与HARQ进程数的范围值的关联关系发送给所述终端，以便终端后续确定自身支持的目标HARQ进程数，实现简便，可用性高。
在一可选实施例中，步骤102可以包括：
基于所述目标HARQ进程数和所述多个预设加扰序列与HARQ进程数的范围值的关联关系，确定所述目标加扰序列。
在本公开实施例中，针对终端支持的目标HARQ进程数大于目标数目的情况，设置了多个预设加扰序列。多个预设加扰序列的数目可以根据目标HARQ进程数来确定，每增加一个预设加扰序列，可以指示的HARQ进程数的数目增加目标数目。
例如，目标数目为16，目标HARQ进程数为32，那么多个预设加扰序列的数目为2。目标HARQ进程数为64，那么多个预设加扰序列的数目为4。
卫星采用多个预设加扰序列中的一个作为目标加扰序列，对DCI进行加扰，终端侧就可以确定自身支持的目标HARQ进程数大于目标数目。另外，为了让终端侧在确定该DCI对应的目标加扰序列时有唯一解，多个预设加扰序列之间可以两两正交。
在确定目标加扰序列时，可以根据目标HARQ进程数和上述关联关系来确定。
在一个示例中，目标HARQ进程数属于目标加扰序列对应的HARQ进程数的目标范围值中的一个。
例如，目标HARQ进程数为32，预设加扰序列2对应的HARQ进程数的范围值是17至32，目标HARQ进程数属于预设加扰序列2对应的HARQ进程数的范围值中的一个值，那么目标加扰序列可以采用预设加扰序列2。目标进程数为64，预设加扰序列2对应的HARQ进程数的范围值是49至64，那么目标加扰序列可以采用预设加扰序列4。
上述实施例中，卫星可以基于终端支持的目标HARQ进程数，以及多个预设加扰序列与HARQ进程数的范围值的关联关系，来确定目标加扰序列，从而可以在不增加DCI信令开销的情况下，将终端支持的超过目标数目的目标HARQ进程数告知终端。
在一可选实施例中，参照图6所示，图6是根据图2所示的实施例示出的另一种用于混合自动重传请求HARQ传输的方法流程图，上述方法还包括：
在步骤106中，基于所述目标加扰序列对应的HARQ进程数的目标范围值和所述目标HARQ进程数，确定所述目标信息域对应的比特值。
在本公开实施例中，目标范围值所包括的每个HARQ进程数，在目标信息域中都有对应的比特值，例如，目标信息域占有的比特长度为4比特，目标范围值为1至16，HARQ进程数1在目标信息域中对应的比特值为0000，HARQ进程数2在目标信息域中对应的比特值为0001，以此类推。根据上述对应关系，可以确定目标HARQ进程数在目标信息域中对应的比特值。
再例如，目标信息域占有的比特长度为4比特，目标加扰序列对应的HARQ进程数的目标范围值是1至16，其中，进程数1在目标信息域中对应的比特值为0000，HARQ进程数2在目标信息域中对应的比特值为0001，以此类推。目标HARQ进程数为1，那么在图4中可以确定目标信息域对应的比特值就为0000。目标加扰序列对应的HARQ进程数的目标范围值 是17至32，进程数17在目标信息域中对应的比特值也为0000，目标HARQ进程数为17，目标信息域的比特值同样为0000。
卫星采用上述方式确定目标信息域对应的比特值后，通过目标加扰序列对DCI进行加扰，将加扰后的DCI发送给终端。后续终端可以根据DCI中目标信息域对应的比特值和目标加扰序列对应的HARQ进程数的目标范围值，确定终端支持的目标HARQ进程数。
上述实施例中，实现了在不增加DCI信令开销的情况下，将终端支持的超过目标数目的目标HARQ进程数告知终端，可用性高。
下面再从终端侧介绍一下本公开提供的用于混合自动重传请求HARQ传输的方法。
本公开实施例提供了一种用于混合自动重传请求HARQ传输的方法，可以用于终端，参照图7所示，图7是根据一实施例示出的另一种用于混合自动重传请求HARQ传输的方法流程图，该方法可以包括以下步骤：
在步骤201中，接收卫星发送的下行控制信息DCI。
在步骤202中，响应于确定对DCI进行加扰的目标加扰序列属于多个预设加扰序列中的一个，基于所述DCI和所述目标加扰序列，确定所述终端支持的目标HARQ进程数。
在本公开实施例中，终端可以按照不同的加扰序列对接收到的DCI进行解扰，在成功解扰的情况下，可以确定卫星侧对DCI进行加扰的目标加扰序列。
针对终端支持的目标HARQ进程数超过目标数目的情况，设置了多个预设加扰序列。多个预设加扰序列的数目可以根据目标HARQ进程数来确定，每增加一个预设加扰序列，可以指示的HARQ进程数可以增加目标数目。其中，目标数目是下行控制信息DCI中用于指示HARQ进程数的目标信息域所指示的最大值。其中，比如目标信息域占用的比特长度为4比特时，可以指示的HARQ进程数的最大值为16，即目标数目为16。比如目标信息域占用的比特长度为5比特时，可以指示的HARQ进程数的最大值 为32，即目标数目为32。多个预设加扰序列之间两两正交。
如果终端确定出目标加扰序列属于多个预设加扰序列中的一个，那么可以基于所述DCI和所述目标加扰序列，确定所述终端支持的目标HARQ进程数。终端支持的目标HARQ进程数是该终端可以并发处理的最多的HARQ进程的数目，且在本公开实施例中，目标HARQ进程数大于目标数目。
上述实施例中，终端可以接收卫星发送的DCI，在确定对DCI进行加扰的目标加扰序列属于多个预设序列中的一个的情况下，可以基于该DCI和目标加扰序列，确定终端支持的目标HARQ进程数，实现了在不增加DCI信令开销的情况下，让终端确定自身支持的更多的目标HARQ进程数。
在一可选实施例中，参照图8所示，图8是根据图7所示的实施例示出的另一种用于混合自动重传请求HARQ传输的方法流程图，上述方法还包括：
在步骤200中，上报终端能力信息给所述卫星。
在本公开实施例中，终端能力信息是与终端支持的HARQ进程相关的信息，包括但不限于buffer size(缓存区大小)等信息。
终端上报自身的终端能力信息给卫星，卫星可以根据该终端能力信息，确定终端支持的目标HARQ进程数。实现简便，可用性高。
在一可选实施例中，参照图9所示，图9是根据图7所示的实施例示出的另一种用于混合自动重传请求HARQ传输的方法流程图，步骤202可以包括：
在步骤202-1中，基于多个预设加扰序列与HARQ进程数的范围值的关联关系，确定所述目标加扰序列对应的HARQ进程数的目标范围值。
例如，目标加扰序列为预设加扰序列2，则根据关联关系，预设加扰序列2对应的HARQ进程数的范围值是17至32，那么目标加扰序列对应的HARQ进程数的目标范围值也是17至32。
在步骤202-2中，基于所述DCI中目标信息域的比特值和所述目标范 围值，确定所述目标HARQ进程数。
在本公开实施例中，目标信息域是所述DCI中用于指示HARQ进程数的信息域。在已经确定了目标加扰序列对应的HARQ进程数的目标范围值的基础上，目标范围值包括的每个HARQ进程数在目标信息域中对应不同的比特值，根据上述对应关系，可以将目标信息域的比特值在目标范围值中对应的HARQ进程数作为目标HARQ进程数。
例如，目标范围值是17至32，目标范围值中进程数17对应的目标信息域的比特值是0000，进程数18对应的目标信息域的比特值是0001，以此类推。如果接收到的DCI中目标信息域的比特值为0000，那么可以确定目标HARQ进程数是17。再例如，接收到的DCI中目标信息域对应的比特值为0010，根据上述对应关系，可以确定目标HARQ进程数是19。
上述实施例中，终端可以基于多个预设加扰序列与HARQ进程数的范围值的关联关系，来确定对DCI加扰的目标加扰序列所对应的HARQ进程数的目标范围值。进一步地，可以基于DCI中目标信息域的比特值和所述目标范围值，确定所述目标HARQ进程数，其中，目标信息域是所述DCI中用于指示HARQ进程数的信息域。实现了在不增加DCI中目标信息域所占用的比特长度的情况下，让终端确定自身支持的更多的目标HARQ进程数。
在一可选实施例中，终端可以采用以下方式中的至少一项确定多个预设加扰序列与HARQ进程数的范围值的关联关系。
第一种方式，接收卫星发送的所述多个预设加扰序列与HARQ进程数的范围值的关联关系。
第二种方式，根据预定设置，确定所述多个预设加扰序列与HARQ进程数的范围值的关联关系。
其中，预定设置包括但不限于在协议中进行约定。
上述实施例中，终端可以接收卫星发送的所述多个预设加扰序列与HARQ进程数的范围值的关联关系，和/或根据预定设置，确定所述多个预 设加扰序列与HARQ进程数的范围值的关联关系，可用性高。
在一可选实施例中，参照图10所示，图10是根据一实施例示出的另一种用于混合自动重传请求HARQ传输的方法流程图，该方法可以包括以下步骤：
在步骤301中，终端上报终端能力信息给卫星。
其中，终端能力信息是与终端支持的HARQ进程相关的信息，包括但不限于buffer size(缓存区大小)等信息。
在步骤302中，卫星基于所述终端能力信息，确定所述终端支持的所述目标HARQ进程数。
其中，终端支持的目标HARQ进程数是该终端可以并发处理的最多的HARQ进程的数目。
在步骤303中，卫星响应于所述目标HARQ进程数大于目标数目，确定多个预设加扰序列与HARQ进程数的范围值的关联关系。
在步骤304中，卫星将所述多个预设加扰序列与HARQ进程数的范围值的关联关系发送给所述终端。
在本公开实施例中，步骤304也可以省略。
在步骤305中，卫星基于所述目标HARQ进程数和所述多个预设加扰序列与HARQ进程数的范围值的关联关系，确定目标加扰序列。
其中，目标数目是下行控制信息DCI中用于指示HARQ进程数的目标信息域所指示的最大值。在本公开实施例中，目标HARQ进程数属于目标加扰序列对应的HARQ进程数的目标范围值中的一个。
在步骤306中，卫星基于所述目标加扰序列对应的HARQ进程数的目标范围值和所述目标HARQ进程数，确定所述目标信息域对应的比特值。
在步骤307中，卫星将通过所述目标加扰序列加扰后的DCI，发送给所述终端。
在步骤308中，终端响应于确定对DCI进行加扰的目标加扰序列属于多个预设加扰序列中的一个，基于所述多个预设加扰序列与HARQ进程数 的范围值的关联关系，确定所述目标加扰序列对应的HARQ进程数的目标范围值。
在本公开实施例中，如果上述步骤304省略，终端可以根据预定设置，确定所述多个预设加扰序列与HARQ进程数的范围值的关联关系。进一步地，确定目标加扰序列对应的HARQ进程数的目标范围值。
在步骤309中，终端基于所述DCI中目标信息域的比特值和所述目标范围值，确定所述目标HARQ进程数。
上述实施例中，可以在不增加DCI中用于指示HARQ进程数的目标信息域所占用的比特长度的情况下，将终端支持的超过目标数目的目标HARQ进程数告知终端。节省了DCI的信令开销，同时终端可以支持更多的HARQ进程数。
