下面结合附图，通过一些实施例及其应用场景对本申请实施例提供的技术方案进行详细地说明。
如图2所示，为本申请一示例性实施例提供的媒体接入控制层重复传输的方法200的流程示意图，该方法200可以但不限于由终端设备执行，具体可由安装于终端设备中的硬件和/或软件执行。本实施例中，所述方法200至少可以包括如下步骤。
S210，终端设备通过多个目标HARQ进程进行MAC PDU的重复传输。
其中，所述终端设备上可配置有至少一个混合自动重传请求(Hybrid automatic repeat request，HARQ)实体，用于调度基于MAC PDU的跨聚合载波(Component Carrier，CC)上的HARQ传输，也即MAC PDU的重复传输。
所述HARQ实体可以包括N个第一HARQ进程，N为大于等于1的整数，如N为1、2、3、……、16。本实施例中，所述第一HARQ进程可以配置有用于进程识别的标识或进程识别序号(Process ID，PID)，使得网络侧设备可基于该标识或进程识别序号指示调度传输的HARQ进程，或终端设备可基于该标识或进程识别序号进行第一HARQ进程的识别。
所述第一HARQ进程包括通过M个不同聚合载波传输的第二HARQ进程，也即，每个第二HARQ进程均关联至一个第一HARQ进程或HARQ实 体，由此可实现不同聚合载波之间的关联，进而可使得网络侧设备基于各不同聚合载波之间的关联关系，通知所述终端设备在多个聚合载波上传输同一个MAC PDU的不同副本数据，以实现MAC PDU的重复传输。其中，M为大于等于1的整数，如M为1、2、3、……、16。
示例性的，如图3所示，为两个聚合载波之间进行关联的关联结果示意图。其中，“第二HARQ进程X_0@CC1”表示属于标识为PID 0的第一HARQ进程、且位于聚合载波CC1上的第二HARQ进程。
应注意，在本实施例中，各所述第二HARQ进程可通过该第二HARQ进程所属的第一HARQ进程的进程识别标识进行识别，也可以通过自身的PID进行识别等。另外，一个HARQ实体中包括的第一HARQ进程的数量小于等于目标聚合载波上的第二HARQ进程的数量，目标聚合载波是多个聚合载波中具有第二HARQ进程数最少的聚合载波，由此，能够确保终端设备基于HARQ实体实现MAC PDU的重复传输时的可靠性。
在此情况下，所述多个目标HARQ进程属于同一个所述第一HARQ进程、且所述目标HARQ进程为所述第一HARQ进程中的任意一个所述第二HARQ进程。例如，假设所述HARQ实体中包括第一HARQ进程M1、M2、M3，第一HARQ进程M1中包括第二HARQ进程A1、A2、A3，第二HARQ进程M2中包括第二HARQ进程B1、B2、B3，第二HARQ进程M2中包括第二HARQ进程C1、C2、C3，那么，所述多个目标HARQ进程可以属于第二HARQ进程M2、且多个所述目标HARQ进程分别为第二HARQ进程B1、B2、B3。
当然，对于前述的HARQ实体，其配置或获取方式可以有多种，例如，所述HARQ实体可以由协议约定、网络侧配置或高层配置等实现。
作为一种可选的实现方式，所述HARQ实体可以是所述终端设备根据第一配置信息和/或第二配置信息配置得到，其中，所述第一配置信息包括以下(11)-(12)中的至少一项。
(11)第一列表，所述第一列表中可以包括至少一个聚合载波的信息(如 聚合载波的标识信息等)，所述聚合载波是用于MAC PDU重复传输的载波。
(12)第二列表，所述第二列表中包括至少一个第一HARQ进程的信息，以及各所述第一HARQ进程中包括的第二HARQ进程的信息，其中，所述第二HARQ进程通过所述聚合载波传输。
所述第二配置信息用于指示各所述聚合载波上传输的第二HARQ进程与第一HARQ进程之间的关联关系。可选的，所述关联关系可以为各所述聚合载波上具有第三标识的第二HARQ进程属于具有第四标识的第一HARQ进程。其中，不同的第二HARQ进程具有的第三标识可以相同或不同。例如，请结合参阅图3，假设不同的第二HARQ进程具有的第三标识不同、且第三标识包括X_0、X_0'，第四标识为PID 0，那么，根据所述第二配置信息可知：聚合载波CC1上传输的第二HARQ进程X_0、聚合载波CC2上传输的第二HARQ进程X_0'属于标识为PID 0的第一HARQ进程。
可选地，所述第一配置信息可以由网络侧设备配置、协议约定或高层配置实现。其中，假设所述第一配置信息是由网络侧设备(如基站)配置，那么，所述网络侧设备可以通过位图(bitmap)或第一信息指示，所述第一信息包括用于所述HARQ实体配置时的起始的第一HARQ进程的标识和第一HARQ进程的数量。也就是说，网络侧设备可以通过bitmap或第一信息配置HARQ实体的进程数和关联关系。
示例性的，假设当前存在X个第一HARQ进程，标识分别为x 0、x 1、x 2、x 3、……、x N、x N+1、……，且所述网络侧设备通过第一信息指示起始的第一HARQ进程的标识为x1、第一HARQ进程的数量为N，那么，所述终端可从X个第一HARQ进程中确定标识为x1的第一HARQ进程，并以所述标识为x1的第一HARQ进程作为起始进程，依次选取标识为x2、x3、……、x N的第一HARQ进程，以配置包括N个第一HARQ进程的HARQ实体。
本实施例中，终端设备通过多个目标HARQ进程实现MAC PDU的重复传输，其中，所述多个目标HARQ进程属于HAR实体中的任一第一HARQ进程。由此，可在关联的多个第二HARQ进程上传输同一MAC PDU的不同 副本数据，进而使得接收方可通过对多个副本数据进行合并处理，以取得MAC PDU重复传输时的合并增益，提高数据传输的准确率，确保无线通信的可靠性。
此外，本实施例是基于相关技术中的按载波的HARQ设计，为MAC PDU重复传输提供一种多聚合载波之间的关联数据传输机制，以实现多聚合载波上的MAC PDU的重复传输。其中，由于多聚合载波之间的关联数据传输机制是在相关技术中的按载波的上行传输许可接收和HARQ实体设计的基础上进行改进，因此，可大幅减少对相关协议的影响，同时降低发送端和接收端的HARQ操作的复杂度。
如图4所示，为本申请一示例性实施例提供的媒体接入控制层重复传输的方法400的流程示意图，该方法400可以但不限于由终端设备执行，具体可由安装于终端设备中的硬件和/或软件执行。本实施例中，所述方法400至少可以包括如下步骤。
S410，所述终端设备在接收到第一指示信息的情况下，确定所述第一指示信息是MAC层重复传输调度指令还是非MAC层重复传输调度指令。
其中，所述MAC层重复传输调度指令用于指示所述终端设备基于前述的HARQ实体进行MAC PDU的重复传输。相应的，所述非MAC层重复传输调度指令用于指示所述终端设备进行除MAC PDU的重复传输之外的其他传输。
本实施例中，可通过多种方式指示MAC层重复传输调度，以便于所述终端设备识别MAC层重复传输调度指令还是非MAC层重复传输调度指令。例如，可以基于无线网络临时标识(Radio Network Temporary Identifier，RNTI)、物理下行控制信道(Physical downlink control channel，PDCCH)格式、控制资源集(Control resource set，CORESET)类型、新数据指示(New Data Indicator，NDI)、指示域等方式中的一种或多种指示MAC层重复传输调度，下面分别对不同方式的实现过程进行说明。
方式1：RNTI
所述终端设备在通过第一RNTI对所述第一指示信息正确接收的情况下，确定所述第一指示信息是所述MAC层重复传输调度指令；相应的，在通过所述第一RNTI对所述第一指示信息解扰失败的情况下，确定所述第一指示信息是所述非MAC层重复传输调度指令。
其中，所述第一RNTI是专用于MAC层重复传输调度的RNTI。本实施例中，可预定义或预配置一个或多个第一RNTI，以用于调度MAC PDU的指令的传输。
可选的，在所述第一RNTI为多个的情况下，各所述第一RNTI与调制和编码方案(Modulation and coding scheme，MCS)列表一一对应，其中，所述第一RNTI用于指示用于MAC层重复传输调度的MCS列表。此外，除了定义专用于MAC层重复传输调度的RNTI之外，也可以复用已有的RNTI进行MAC层重复传输调度，如小区无线网络临时标识(C-RNTI)、寻呼RNTI(P-RNTI)等，在此不做限制。
方式2：PDCCH格式
在所述第一指示信息通过PDCCH传输、且所述PDCCH的格式为第一格式(Format 1)的情况下，确定所述第一指示信息是所述MAC层重复传输调度指令；相应的，在所述第一指示信息通过PDCCH传输、且所述PDCCH的格式不为第一格式的情况下，确定所述第一指示信息是所述非MAC层重复传输调度指令。
其中，所述第一格式专用于传输MAC层重复传输的调度指令。可选的，可以预定义或预配置一个或多个PDCCH格式。例如，预定义PDCCH format 1，用于进行MAC层重复传输，预定义PDCCH format 2，用于进行非MAC层重复传输等，在此不做限制。
方式3：CORESET的类型
在所述第一指示信息是通过CORESET资源传输、且所述CORESET资源为第一CORESET资源的情况下，确定所述第一指示信息是所述MAC层重复传输调度指令；相应的，在所述第一指示信息是通过CORESET资源传 输、但所述CORESET资源不为第一CORESET资源的情况下，确定所述第一指示信息是所述非MAC层重复传输调度指令。
其中，所述第一CORESET资源专用于传输MAC层重复传输的调度指令。可选的，可以预定义或配置一个或多个CORESET资源，以用于传输MAC层重复传输的调度指令。
方式4：HARQ进程的标识
在承载所述第一指示信息的HARQ进程的标识位于第一区间的情况下，确定所述第一指示信息是所述MAC层重复传输调度指令；相应的，在承载所述第一指示信息的HARQ进程的标识未位于第一区间的情况下，确定所述第一指示信息是所述非MAC层重复传输调度指令。
其中，所述第一区间是第一HARQ进程的标识区间。本实施例中，是利用扩展的HARQ进程的标识(Identifier，ID)区间指示MAC层重复传输的调度。
示例性的，假设各聚合载波上的第二HARQ进程的PID的范围为{0，Y(16)-1}，Y为聚合载波上具有的第二HARQ进程的最大数量，在此情况下，可进一步扩大该聚合载波上的HARQ PID的范围至{0，2Y(16)-1}，那么，当承载所述第一指示信息的HARQ进程的标识位于{0，Y(16)-1}这一区间时，可确定所述第一指示信息是所述非MAC层重复传输调度指令，当承载所述第一指示信息的HARQ进程的标识位于{Y(16)-1，2Y(16)-1}这一区间(即前述的第一区间)时，可确定所述第一指示信息是所述MAC层重复传输调度指令。
需要注意，在本实施例中，所述“区间”也可以理解为空间、区域等，在此不做限制。
方式5：NDI
在承载所述第一指示信息的第一HARQ进程对应的NDI为第一值的情况下，确定所述第一指示信息是所述MAC层重复传输调度指令。相应的，在承载所述第一指示信息的第一HARQ进程对应的NDI为第二值的情况下， 确定所述第一指示信息是所述非MAC层重复传输调度指令。
其中，本实施例可以是基于扩大NDI的方式实现，如由1bit扩大至2bit，进而通过NDI的不同值指示所述MAC层重复传输调度指令或非MAC层重复传输调度指令。
可选地，所述第一值包括第一子值和第二子值，所述第一子值与所述第二子值互为反转，例如，所述第一子值为“00”，第二子值为“01”，那么，“00”和“01”互为反转。
所述第二值包括第三子值和第四子值，所述第三子值和所述第四子值互为反转。例如，所述第三子值为“10”，第四子值为“11”，那么，“10”和“11”互为反转。
可以理解，在NDI值发生反转的情况下，确定目标HARQ进程对应的HARQ传输为初传，在NDI值未发生反转的情况下，确定目标HARQ进程对应的HARQ传输为重传。另外，所述NDI值可携带在所述第一指示信息中。
方式6：指示域
在所述第一指示信息中包括第一指示域的情况下，确定所述第一指示信息是所述MAC层重复传输调度指令；相应的，在所述第一指示信息中未包括第一指示域的情况下，确定所述第一指示信息是所述非MAC层重复传输调度指令。
其中，所述第一指示域可以是在所述调度指令中新增加的第一个指示域，且专用于指示MAC层重复传输调度，也可以通过复用其他指示域的方式，以指示MAC层重复传输调度，在此不做限制。
在前述给出的几种MAC层重复传输调度指令识别方式中，如果所述第一指示信息为MAC层重复传输调度指令，那么，所述第一指示信息中可携带有第一标识或第二标识；所述第一标识是所述目标HARQ进程所属的第一HARQ进程的标识；所述第二标识是所述目标HARQ进程的标识。
换言之，由于第一HARQ进程与各聚合载波上的第二HARQ进程之间 具有关联关系，那么，不管是网络侧设备通过MAC层重复传输调度指令指示第一HARQ进程，还是指示与第一HARQ进程关联的各聚合载波上的第二HARQ进程，所述终端设备均可以确定出用于MAC PDU重复传输的第二HARQ进程，即目标HARQ进程。
S420，在确定所述第一指示信息是所述MAC层重复传输调度指令的情况下，终端设备通过多个目标HARQ进程进行MAC PDU的重复传输。
其中，所述终端设备上配置有HARQ实体，所述HARQ实体包括N个第一HARQ进程，所述第一HARQ进程包括M个通过不同聚合载波传输的第二HARQ进程，所述多个目标HARQ进程是属于同一个所述第一HARQ进程、且所述目标HARQ进程为所述第一HARQ进程中的任意一个所述第二HARQ进程，M、N为大于等于1的整数。
可以理解，S420的实现过程除了可参照前述方法实施例200中的相关描述之外，作为一种可能的实现方式，所述终端设备通过多个目标HARQ进程进行MAC PDU的重复传输的步骤之前，所述方法还包括以下(21)-(24)中的至少一项。
(21)在所述目标HARQ进程对应的NDI是第一个发生反转或所述目标HARQ进程对应的HARQ传输为初传的情况下，所述终端设备创建所述MAC PDU，其中，所述MAC PDU用于所述目标HARQ进程对应的HARQ传输以及与所述目标HARQ进程属于同一个第一HARQ进程的其他第二HARQ进程的传输。
也就是，MAC实体可以仅为最先发生反转或初传的聚合载波上的第二HARQ进程创建MAC PDU，而创建的该MAC PDU也可以用于其他聚合载波上与指定的第一HARQ进程关联的其他第二HARQ进程的后继HARQ传输，直到下一个存在第二HARQ进程对应的NDI发生反转。其中，指定的第一HARQ是最先发生反转或初传的聚合载波上的第二HARQ进程所属的第一HARQ进程。
(22)所述目标HARQ进程对应的NDI，根据所述目标HARQ进程所 属的第一HARQ进程对应的NDI确定。
也即是，第二HARQ进程对应的NDI可以按第一HARQ进程来维护，即当第一HARQ进程传输新的MAC PDU时，NDI反转，网络侧设备调度属于该第一HARQ进程的第二HARQ进程进行传输时，直接使用该第二HARQ进程的NDI。
此外，在本实施例中，第二HARQ进程NDI可以按第二HARQ进程来维护，即当第二HARQ进程传输新的MAC PDU时，NDI反转，反之，则不反转。
(23)在未创建所述目标HARQ进程对应的MAC PDU、但已创建第三HARQ进程对应的MAC PDU的情况下，将所述第三HARQ进程对应的MAC PDU确定为所述目标HARQ进程对应的MAC PDU，其中，所述目标HARQ进程与所述第三HARQ进程属于同一个第一HARQ进程。
(24)在未创建所述目标HARQ进程对应的MAC PDU、且未创建第三HARQ进程对应的MAC PDU的情况下，通过MAC实体创建目标HARQ进程对应的所述MAC PDU。此外，NDI也可以按第二HARQ进程分别维护，当MAC实体确定需要为第二HARQ进程A1创建MAC PDU时，需要先确定是否已经为与第二HARQ进程A1属于同一个第一HARQ进程的其他任一第二HARQ进程A2创建了新的MAC PDU。如果没有，则MAC实体为所述第二HARQ进程A1创建新MAC PDU；否则直接使用第二HARQ进程A2对应的MAC PDU。
例如，对于前述(23)和(24)，MAC实体收到的聚合载波1上的使用第一HARQ进程x的MAC PDU传输调度时，如果属于第一HARQ进程x的所有第二HARQ进程x为空闲态，则MAC实体为所述第二HARQ进程x创建新MAC PDU i1。如果此前MAC实体已经为任一其它聚合载波2上的与第一HARQ进程x对应的第二HARQ进程创建了MAC PDU i2，且其NDI与所述聚合载波1上收到的MAC PDU传输调度确定的NDI相同，则MAC实体将MAC PDU i2用于所述聚合载波1上的所调度的MAC PDU重复传输。
进一步，基于前述媒体接入控制层重复传输的方法的描述，属于同一个第一HARQ进程的各聚合载波上的所有第二HARQ进程，可以共享同一个HARQ缓存(buffer)。
在此情况下，当终端设备接收到MAC层重复传输调度指令A，且该MAC层重复传输调度指令A指示聚合载波X上的第二HARQ进程NDI反转，那么，所述终端设备可生成新的MAC PDU并存入共享HARQ buffer，以及通过聚合载波X上的第二HARQ进程在MAC层重复传输调度指令A所指示的资源上传输该MAC PDU。随后，当所述终端设备收到的MAC层重复传输调度指令B，该MAC层重复传输调度指令B指示聚合载波Y(X可以等于或不等于Y)上的第二HARQ进程的NDI与所述聚合载波X上的第二HARQ进程传输的NDI相同，那么，所述终端设备可以从共享HARQ buffer取出MAC PDU数据，并通过聚合载波Y上的第二HARQ进程在MAC层重复传输调度指令指示的资源上传输该MAC PDU。
本实施例中，按照载波维度，进一步对与MAC PDU重复传输相关的MAC层重复传输调度指令进行设计，能够进一步降低MAC层重复传输时对HARQ操作的复杂度，确保MAC层重复传输的高效性。
如图5所示，为本申请一示例性实施例提供的媒体接入控制层重复传输的方法500的流程示意图，该方法500可以但不限于由终端设备执行，具体可由安装于终端设备中的硬件和/或软件执行。本实施例中，所述方法500至少可以包括如下步骤。
S510，所述终端设备根据第二指示信息对目标MAC层重复传输配置执行第一操作。
其中，所述第二指示信息可以通过PDCCH命令(order，也即PDCCH)、媒体访问控制控制单元(Medium Access Control-Control Element，MAC CE)或无线资源控制(Radio Resource Control，RRC)信令传输。也就是说，所述目标MAC层重复传输配置可通过PDCCH命令、MAC CE或RRC信令进 行激活、去激活等操作。
可选地，在通过PDCCH传输所述第二指示信息的情况下，所述PDCCH可通过第一RNTI进行传输(如加扰)，所述第一RNTI是专用于MAC层重复传输调度的RNTI。也就是说，在通过PDCCH传输所述第二指示信息的情况下，也可以通过第一RNTI对承载MAC层重复传输调度指令的PDCCH进行加扰，以实现MAC层重复传输的调度，由此进一步降低MAC层重复传输调度的复杂性。
所述目标MAC层重复传输配置(MAC PDU configuration)包括数据流对应的MAC层重复传输配置、数据无线承载(Data Radio Bearer，DRB)对应的MAC层重复传输配置或逻辑信道(logical channel，LCH)对应的MAC层重复传输配置。也就是，可以按照数据流、DRB或LCH为终端设备配置MAC层重复传输配置。
此外，一个所述终端设备可以配置一个或多个MAC层重复传输配置，如上行的MAC层重复传输配置、下行的MAC层重复传输配置等，且每个MAC层重复传输配置可以具有一个ID，即MAC PDU configuration ID。可以理解，在所述终端设备配置有多个MAC层重复传输配置时，所述目标MAC层重复传输配置属于所述多个MAC层重复传输配置。
一种实现方式中，以所述目标MAC层重复传输配置为例，所述目标MAC层重复传输配置可以是所述终端设备根据RRC信令配置信息配置得到，其中，所述RRC信令配置信息包括以下(31)-(35)中的至少一项。
(31)第三列表，所述第三列表中包括聚合载波的信息，所述聚合载波用于MAC层重复传输。
(32)第一配置信息和/或第二配置信息，所述第一配置信息和/或所述第二配置信息用于配置所述HARQ实体。
其中，所述第一配置信息和/或第二配置信息的实现过程可以参照前述方法实施例200中的相关描述，为避免重复，在此不再赘述。
(33)第三配置信息，所述第三配置信息用于配置MAC层重复传输调 度信令，如所述终端设备识别MAC层重复传输调度信令的方式、参数等，详细可参照方法实施例300中的相关描述，为避免重复，在此不再赘述。
(34)第四配置信息，所述第四配置信息用于配置MAC层重复传输许可，和/或，所述MAC层重复传输时的默认状态，和/或，所述MAC层重复传输配置对应粒度(如数据流、DRB或LCH等)，所述默认状态包括开启状态或关闭状态。
其中，在所述默认状态为开启状态时，可确定所述终端设备可以进行MAC层重复传输，反之，可确定所述终端设备禁止MAC层重复传输。
(35)MAC层重复传输对应的信道状态信息(Channel State Information，CSI)汇报配置。其中，所述CSI状态配置可以是rank配置等。
当然，所述第一操作可以包括以下至少(41)-(44)中的任一种。
(41)完全激活：用于指示经过完全激活后，所述目标MAC层重复传输配置对应的所有聚合载波参与MAC层重复传输。
(42)部分激活：用于指示经过部分激活后，所述目标MAC层重复传输配置对应的至少部分MD CC参与MAC层重复传输。
在所述第一操作为所述部分激活的情况下，所述第二指示信息中可携带有需要进行激活的聚合载波的信息，该信息可以是需要进行部分激活的聚合载波的标识，以用于终端设备识别到需要进行去激活操作的聚合载波。
(43)完全去激活：用于指示经过完全去激活后，所述目标MD配置对应的所有MD CC均不参与MAC层重复传输。
(44)部分去激活：用于指示经过部分去激活后，所述目标MD配置对应的至少部分MD CC不参与MAC层重复传输。
其中，在所述第一操作为所述部分去激活的情况下，所述第二指示信息中携带有需要进行去激活的聚合载波的信息，该信息可以是需要进行去激活的聚合载波的标识，以用于终端设备识别到需要进行去激活操作的聚合载波。
对于前述(41)-(44)中给出的几种操作中，如果所述终端设备配置有多个MAC层重复传输配置，则所述第二指示信息中携有带需要激活或去激 活的MAC层重复传输配置的标识，以便于所述终端设备识别到需要激活或去激活的目标MAC层重复传输配置。
S520，在所述第一操作为所述完全激活或部分激活的情况下，所述终端设备通过多个目标HARQ进程进行MAC PDU的重复传输。
其中，所述终端设备上配置有HARQ实体，所述HARQ实体包括N个第一HARQ进程，所述第一HARQ进程包括M个通过不同聚合载波传输的第二HARQ进程，所述多个目标HARQ进程是属于同一个所述第一HARQ进程、且所述目标HARQ进程为所述第一HARQ进程中的任意一个所述第二HARQ进程，M、N为大于等于1的整数。
可以理解，S520的实现过程除了可参照前述方法实施例200和/或400中的相关描述之外，在本实施例中，所述目标HARQ进程是所述目标MAC层重复传输配置中被激活的聚合载波上的第二HARQ进程。
基于前述方法实施例200-500的描述，所述终端设备除了可以实现方法
实施例200-300的过程之外，还可以基于方法实施例200和300实现MAC层重复传输。例如，以LCH对应的MAC层重复传输配置为例，网络侧设备可以配置LCH对应的MAC层重复传输配置，那么，如果一个LCH配置有MAC PDU许可或MAC层重复传输配置的标识，且对应的MAC层重复传输配置处于激活状态，则所述终端设备在接收到MAC层重复传输调度信令后，可以对该逻辑信道的数据进行MAC层重复传输。
此外，作为一种可能的实现方式，所述终端设备通过多个目标HARQ进程进行MAC PDU的重复传输的步骤之后，所述方法还可以包括以下(51)-(53)中的至少一项。
(51)考虑到多个目标HARQ进程关联至一个第一HARQ进程，因此，所述终端设备在正确传输所述MAC PDU的情况下，可基于所述多个目标HARQ进程中的至少一个目标HARQ进程反馈确认信息(如肯定确认(Acknowledgement，ACK)消息)。
(52)在任意一个所述目标HARQ进程上的HARQ传输正确的情况下， 可确定所述目标HARQ进程可用于新的MAC PDU调度，因此，可将所述目标HARQ进程所属的第一HARQ进程配置为空闲态(也即可用状态)。
(53)考虑到多个目标HARQ进程关联至一个第一HARQ进程，那么，在任意一个所述目标HARQ进程上的HARQ传输正确的情况下，可确定所述目标HARQ所属的第一HARQ进程可用于新的MAC PDU调度，因此，可将与所述目标HARQ进程属于同一个第一HARQ进程的其它第二HARQ进程配置为空闲态(也即可用状态)。
S530，在所述第一操作为所述完全去激活或部分去激活的情况下，所述终端设备停止在第一聚合载波上检测MAC层重复传输调度指令。
其中，所述第一聚合载波是所述目标MAC层重复传输配置中去激活的聚合载波。
本实施例中，按照载波维度，进一步对与MAC PDU重复传输相关的MAC层重复传输配置、配置激活/去激活信令进行设计，由此，一方面，能够在实现MAC PDU重复传输的同时，进一步确保无线通信的可靠性；另一方面，本实施例是在现有按载波的上行传输许可接收和HARQ实体设计的基础上进行MAC PDU重复传输机制改进，能够尽量减少对相关传输协议的影响，以及降低发送端和接收端的HARQ操作的复杂度。
需要说明的是，本申请实施例提供的媒体接入控制层重复传输的方法，执行主体可以为媒体接入控制层重复传输的装置，或者，该媒体接入控制层重复传输的装置中的用于执行媒体接入控制层重复传输的方法的控制模块。本申请实施例中以媒体接入控制层重复传输的装置执行媒体接入控制层重复传输的方法为例，说明本申请实施例提供的媒体接入控制层重复传输的装置。
