在第五代(5 th generation，5G)新无线(new radio，NR)中，有两种上行资源调度机制。一种是动态授权(dynamic grant，DG)，网络设备每次调度上行DG时，都通过下行控制信息(downlink control information，DCI)向终端指示被调度的上行传输资源的时频位置等信息。另一种是配置授权(configured grant，CG)，网络设备采用CG为终端配置CG资源时，部分参数，例如CG资源的周期、使用CG资源的混合自动重传请求(hybrid automatic repeat request，HARQ)进程数目等参数，由网络设备通过无线资源控制(radio resource control，RRC)信令提供给终端，CG资源的时频位置、调制编码策略(modulation and coding scheme，MCS)等可以由网络设备通过RRC信令提供给终端，也可以由网络设备通过DCI提供给终端。
在NR中，可以采用CG和/或DG机制为终端配置多块上行资源，多块上行资源在时域上可以重叠也可以不重叠，当为终端配置的多块上行资源在时域上重叠时，终端需要基于一定的准则选择在哪一块上行资源上传输信号。以终端被配置两块在时域上有重叠的上行资源为例，一种准则中，终端可以选择在两块上行资源中优先级较高的上行资源上传输信号，基于该准则网络设备在优先级较低的上行资源上接收不到信号，在该过程中，终端可能已针对优先级较低的上行资源组成媒体接入控制(media access control，MAC)层协议数据单元(protocol data unit，PDU)或未组成MAC PDU，或终端可能针对优先级较低的上行资源有数据存储在对应的缓存中或没有数据存储在对应的缓存中，目前针对该场景，一种处理方式中网络设备默认终端启用了跳过(skip)机制，无论终端是否针对优先级较低的上行资源组包或是否针对优先级较低的上行资源有数据缓存，网络设备均不调度优先级较低的上行资源的重传，此时可能造成针对优先级较低的上行资源所组MAC PDU丢失，另一种处理方式中为减少数据包丢失，无论终端是否针对优先级较低的上行资源组包或是否针对优先级较低的上行资源有数据缓存，网络设备均为优先级较低的上行资源调度一块重传资源，此时可能造成调度资源的浪费。显然，这两种处理方式均不适用于该场景。

具体实施方式
首先，对本申请中的部分用语进行解释说明，以便于本领域技术人员理解。
1)终端，又称之为用户设备(user equipment，UE)、移动台(mobile station，MS)、移动终端(mobile terminal，MT)等，是指向用户提供语音和/或数据连通性的设备。例如，具有无线连接功能的手持式设备、车载设备等。目前，一些终端的举例为：手机(mobile phone)、平板电脑、笔记本电脑、掌上电脑、移动互联网设备(mobile internet device，MID)、可穿戴设备，虚拟现实(virtual reality，VR)设备、增强现实(augmented reality，AR)设备、工业控制(industrial control)中的无线终端、无人驾驶(self driving)中的无线终端、远程手术(remote medical surgery)中的无线终端、智能电网(smart grid)中的无线终端、运输安全(transportation safety)中的无线终端、智慧城市(smart city)中的无线终端、智慧家庭(smart home)中的无线终端等。
2)网络设备，是无线网络中的设备，例如网络设备可以为将终端接入到无线网络的无线接入网(radio access network，RAN)节点(或设备)，又可以称为基站。目前，一些RAN节点的举例为：继续演进的节点B(gNB)、传输接收点(transmission reception point，TRP)、演进型节点B(evolved Node B，eNB)、无线网络控制器(radio network controller，RNC)、节点B(Node B，NB)、基站控制器(base station controller，BSC)、基站收发台(base transceiver station，BTS)、家庭基站(例如，home evolved NodeB，或home Node B，HNB)、基带单元(base band unit，BBU)，或无线保真(wireless fidelity，Wifi)接入点(access point，AP)等。另外，在一种网络结构中，网络设备可以包括集中单元(centralized unit，CU)节点、或分布单元(distributed unit，DU)节点、或包括CU节点和DU节点的RAN设备。其中包括CU节点和DU节点的RAN设备将长期演进(long term evolution，LTE)系统中eNB的协议层拆分开，部分协议层的功能放在CU集中控制，剩下部分或全部协议层的功能分布在DU中，由CU集中控制DU。又例如网络设备可以是为终端提供业务支持的核心网(core network，CN)设备，常见的核心网设备包括接入和移动性管理功能(access and mobility management function，AMF)实体、会话管理功能(session management function，SMF)实体、用户面功能(user plane function，UPF)实体等等，此处不一一列举。其中，所述AMF实体可以负责终端的接入管理和移动性管理；所述SMF实体可以负责会话管理，如用户的会话建立等；所述UPF实体可以是用户面的功能实体，主要负责连接外部网络。
无论是RAN设备还是CN设备均可以作为所述网络设备，执行本申请实施例中网络设备执行的方法。
3)上行资源调度机制，下面介绍两种上行资源调度机制。一种是动态调度，网络设备每次调度上行动态授权(dynamic grant，DG)时，都通过下行控制信息(downlink control information，DCI)指示被调度的上行传输资源的时频位置等信息。另一种是配置授权(configured grant，CG)，目前对该两类配置授权分别定义为配置授权类型1(configured grant type 1)和配置授权类型2(configured grant type 2)。
基于以上两种上行资源调度方式，可以将调度的上行资源分为两大类，将通过动态调度的方式调度的上行资源称为DG资源或称为DG类型资源或称为DG，将通过配置授权的方式调度的上行资源称为CG资源或称为CG类型资源或称为CG，本申请对上行资源的名称不做限定。
其中，配置授权类型1的时频资源位置、CG资源的周期、使用CG资源的混合自动 重传请求(hybrid automatic repeat request，HARQ)进程数目、调制编码策略(modulation and coding scheme，MCS)等参数，由网络设备通过无线资源控制(radio resource control，RRC)信令提供给终端，并由终端存储为配置上行授权(configured uplink grant)，进而终端可使用该配置授权进行上行数据传输；配置授权类型2的CG资源的周期、使用CG资源的HARQ进程数目等参数，由网络设备通过RRC信令提供给终端，配置授权类型2的时频资源位置、MCS等由网络设备通过DCI提供给终端，并由终端存储为配置上行授权，即配置授权类型2可以由物理层(physical layer，PHY)或层1(L1)信令控制激活或去激活，当网络设备通过DCI激活配置授权类型2时，时频资源位置由网络设备通过DCI提供给终端，并由终端存储为配置上行授权，进而终端可使用该配置授权进行上行数据传输。
4)资源跳过(skip)机制，是指当终端被配置上行资源后，若针对该上行资源终端无合适的待传输数据，则终端skip该上行资源，也就是，终端不会针对该上行资源生成MAC PDU。
若采用CG为终端配置上行资源，当终端被配置一个CG资源时，若针对该CG资源终端没有合适的待传输上行数据，则终端会skip该CG资源，即终端不会针对该CG资源生成MAC PDU。
若采用动态调度为终端配置上行资源，终端可以配置上行动态传输的skip机制，例如，可以通过RRC信令携带的参数skipUplinkTxDynamic来指示是否配置上行动态传输的skip机制。当配置了上行动态传输的skip机制时，若终端被配置一个DG资源，且针对该DG资源终端没有合适的待传输上行数据，则终端会skip该DG资源，即终端不会针对该DG资源生成MAC PDU。
5)传输块(transport block，TB)，是指MAC PDU在物理层形成的传输块，一个TB中可以包括多个比特。
6)载波，可以是指用于调制待发送信号的无线电波，例如，正弦波。
7)带宽部分(band width part，BWP)，是指为适配终端的带宽能力，在载波带宽内为终端配置的资源，例如，载波带宽上一组连续的或不连续的RB，一个载波中可配置多个BWP，例如一个载波可以配置4个BWP。
8)“多个”是指两个或两个以上，其它量词与之类似。“和/或”描述关联对象的关联关系，表示可以存在三种关系，例如，A和/或B，可以表示：单独存在A，同时存在A和B，单独存在B这三种情况。此外，对于单数形式“a”，“an”和“the”出现的元素(element)，除非上下文另有明确规定，否则其不意味着“一个或仅一个”，而是意味着“一个或多于一个”。例如，“a device”意味着对一个或多个这样的device。再者，至少一个(at least one of).......”意味着后续关联对象中的一个或任意组合，例如“A，B和C中的至少一个”包括A，B，C，AB，AC，BC，或ABC。
需要说明的是，在本申请的描述中，“第一”、“第二”等词汇，仅用于区分描述的目的，而不能理解为指示或暗示相对重要性，也不能理解为指示或暗示顺序。
下面结合说明书附图对本申请的技术方案作进一步地详细描述。
请参考图1，其为本申请实施例可应用的一种通信系统的示意图。如图1所示，终端130可接入到无线网络，以通过无线网络获取外网(例如因特网)的服务，或者通过无线网络与其它设备通信，如可以与其它终端通信。该无线网络包括RAN110和CN120，其中RAN110用于将终端130接入到无线网络，CN120用于对终端进行管理并提供与外网通信 的网关。应理解，图1所示的通信系统中各个设备的数量仅作为示意，本申请实施例并不限于此，实际应用中在通信系统中还可以包括更多的终端130、更多的RAN110，还可以包括其它设备。
本申请对图1所示的通信系统的类型不做限定，例如可以是LTE系统，也可以是NR系统，当然也可以是未来的通信系统。
CN120中可以包括多个CN设备，当图1所示的通信系统为NR系统时，CN120中可以包括AMF实体、UPF实体、或SMF实体等，当图1所示的通信系统为LTE系统时，CN120中可以包括移动性管理实体(mobility management entity，MME)和服务网关(serving gateway，S-GW)等。
请参考图2，其为本申请实施例提供的一种网络架构的示意图。如图2所示，该网络架构包括CN设备和RAN设备。其中RAN设备包括基带装置和射频装置，其中基带装置可以由一个节点实现，也可以由多个节点实现，射频装置可以从基带装置拉远独立实现，也可以集成在基带装置中，或者部分拉远部分集成在基带装置中。例如，在LTE系统中，RAN设备(eNB)包括基带装置和射频装置，其中射频装置可以相对于基带装置拉远布置，例如射频拉远单元(remote radio unit，RRU)相对于BBU拉远布置。
RAN设备和终端之间的通信遵循一定的协议层结构。例如控制面协议层结构可以包括无线资源控制(radio resource control，RRC)层、分组数据汇聚层协议(packet data convergence protocol，PDCP)层、无线链路控制(radio link control，RLC)层、媒体接入控制(media access control，MAC)层和物理层等协议层的功能。用户面协议层结构可以包括PDCP层、RLC层、MAC层和物理层等协议层的功能；在一种实现中，PDCP层之上还可以包括业务数据适配(service data adaptation protocol，SDAP)层。
RAN设备可以由一个节点实现RRC、PDCP、RLC和MAC等协议层的功能；或者可以由多个节点实现这些协议层的功能；例如，在一种演进结构中，RAN设备可以包括集中单元(centralized unit，CU)和分布单元(distributed unit，DU)，多个DU可以由一个CU集中控制。如图2所示，CU和DU可以根据无线网络的协议层划分，例如PDCP层及以上协议层的功能设置在CU，PDCP以下的协议层，例如RLC层和MAC层等的功能设置在DU。
这种协议层的划分仅仅是一种举例，还可以在其它协议层划分，例如在RLC层划分，将RLC层及以上协议层的功能设置在CU，RLC层以下协议层的功能设置在DU；或者，在某个协议层中划分，例如将RLC层的部分功能和RLC层以上的协议层的功能设置在CU，将RLC层的剩余功能和RLC层以下的协议层的功能设置在DU。此外，也可以按其它方式划分，例如按时延划分，将处理时间需要满足时延要求的功能设置在DU，不需要满足该时延要求的功能设置在CU。
此外，射频装置可以拉远，不放在DU中，也可以集成在DU中，或者部分拉远部分集成在DU中，在此不作任何限制。
请继续参考图3，相对于图2所示的网络架构，还可以将CU的控制面(CP)和用户面(UP)分离，分成不同实体来实现，分别为控制面CU实体(CU-CP实体)和用户面CU实体(CU-UP实体)。
在以上网络架构中，CU产生的信令可以通过DU发送给终端，或者终端产生的信令可以通过DU发送给CU。DU可以不对该信令进行解析而直接通过协议层封装而透传给终 端或CU。以下实施例中如果涉及这种信令在DU和终端之间的传输，此时，DU对信令的发送或接收包括这种场景。例如，RRC或PDCP层的信令最终会处理为PHY层的信令发送给终端，或者，由接收到的PHY层的信令转变而来。在这种架构下，该RRC或PDCP层的信令，即也可以认为是由DU发送的，或者，由DU和射频装载发送的。
在以上实施例中可以将CU划分为RAN侧的网络设备，此外，也可以将CU划分为CN侧的网络设备，在此不做限制。
本申请以下实施例中的装置，根据其实现的功能，可以位于终端或网络设备。当采用以上CU-DU的结构时，网络设备可以为CU节点、或DU节点、或包括CU节点和DU节点的RAN设备。
以图1所示的通信系统为例，RAN110可以采用CG和/或DG机制为终端130配置多块上行资源，多块上行资源在时域上可以重叠也可以不重叠，当为终端130配置的多块上行资源在时域上重叠时，终端130基于一定的准则选择在哪一块上行资源上传输信号。下面以一个例子进行说明。
请参考图4，其为本申请实施例提供的一种上行资源配置示意图。图4中以为终端130配置了两块在时域上重叠的上行资源为例示意，两块在时域上重叠的上行资源分别为第1上行资源和第2上行资源，其中，第1上行资源和第2上行资源均可以为CG资源或DG资源，假设图4中以第1上行资源为CG资源、第2上行资源为DG资源为例示意，终端在有交叠的多块上行资源的重叠部分只在一块上行资源上传输，因此，终端130基于一定的准则选择在CG资源还是在DG资源上传输信号，一种基于优先级的准则中，终端130可以选择在CG资源和DG资源中优先级较高的资源上传输信号，假设图4中DG资源的优先级高于CG资源的优先级，则终端130可以选择在DG资源上传输信号，终端130在何时处理上行资源是终端130自身的实现行为，也就是说终端处理上行资源的时机在实现中是有不同情形的。例如，在终端130确定在DG资源上传输信号的过程中，终端130在处理CG资源时，可以有如下情形：
第一种情形，终端130已针对CG资源组成MAC PDU或者终端130已将针对CG资源所组成的数据包存储在对应HARQ进程的缓存中，但未通过所述CG资源发送所述MAC PDU或所述数据包。例如，终端130的MAC实体未获得DG资源的信息，故针对CG资源组成MAC PDU，MAC实体组成MAC PDU之后，可将其递交至PHY实体，PHY实体可将该MAC PDU存储在相应的缓存中，此时缓存中的数据即为针对CG资源所组成的数据包，若PHY实体确定DG资源的优先级更高，则放弃在CG资源上传输信号，也就是，在这种情况中，终端130虽已针对CG资源组成MAC PDU或已将与CG资源对应的数据存储在对应的缓存中，但未通过该CG资源发送该MAC PDU或与CG资源对应的数据。
第二种情形，终端130未针对CG资源组成MAC PDU或者没有针对CG资源所组成的数据包存储在对应的缓存中。例如，当为终端130配置的CG资源到达时，针对该CG资源终端130没有合适的待传输数据，则skip该CG资源，不根据该CG资源生成MAC PDU。又例如，终端130的MAC实体确定后续有优先级更高的DG资源需要传输数据，则终端130的MAC实体忽略该CG资源，不针对该CG资源组成MAC PDU。再如，终端130的MAC实体针对CG资源组成MAC PDU，MAC实体组成MAC PDU之后，由于DG资源的优先级更高，没有将MAC PDU递交至PHY实体，此时没有针对CG资源所组成的数据包存储在对应的缓存中。
目前针对上述场景，一种处理方式中RAN110默认终端130启用了跳过(skip)机制，当RAN110在CG资源上接收不到信号时，认为终端130在该CG资源上没有合适的信号传输，故不会调度该CG资源的重传，而实际中，终端130可能并没有skip该CG资源，而是针对该CG资源组成MAC PDU或已将与该CG资源对应的数据存储在相应的缓存中，这种情况下，若RAN110不调度该CG资源的重传，可能会导致数据丢失，进而影响用户体验。另一种处理方式中，针对上述场景RAN110被配置为一直调度该CG资源的重传，而实际中，终端130可能未针对CG资源组成MAC PDU或者没有针对CG资源的数据存储在对应的缓存中，这种情况下，若RAN110调度该CG资源的重传，则会增加信令开销，且浪费重传资源。
鉴于上述存在的问题，本申请实施例提供一种通信方法，在该方法中，针对上行资源在时域上重叠的场景，终端确定在重叠部分采用优先级较高的上行资源发送信号时，可以向网络设备指示针对优先级较低的上行资源是否组成MAC PDU或针对优先级较低的上行资源是否有数据存储在对应的缓存中，这样，网络设备便可根据终端的指示，确定终端针对优先级较低的上行资源是否组成MAC PDU或针对优先级较低的上行资源是否有数据存储在对应的缓存中，若网络设备根据终端的指示确定针对优先级较低的上行资源组成MAC PDU，则网络设备可以调度资源对该MAC PDU进行传输或重传，若网络设备根据终端的指示确定针对优先级较低的上行资源有数据存储在对应的缓存中，则网络设备可以调度资源对该数据进行传输或重传，若网络设备根据终端的指示确定针对优先级较低的上行资源未组成MAC PDU或针对优先级较低的上行资源没有数据存储在对应的缓存中，则网络设备无需调度资源对该优先级较低的上行资源所关联HARQ进程中缓存的数据进行传输或重传。
本申请实施例提供的方法可以应用于NR系统、LTE系统、LTE车联网(vehicle to everything，V2X)系统、NR车联网系统、下一代无线局域网系统或统一接入回传(integrated access backhaul，IAB)系统，本申请对此不做限定。
请参考图5，其为本申请实施例提供的一种通信方法的实施流程图。参阅图5所示，该方法包括：
步骤101：终端确定在时域上有重叠部分的第一上行资源和第二上行资源中，第一上行资源的优先级高于第二上行资源的优先级。本申请实施例中，第一上行资源和第二上行资源在频域上可以重叠也可以不重叠；第一上行资源和第二上行资源可以是同一个载波上不同BWP上的资源，也可以是同一个载波上相同BWP上的资源。第一上行资源可以是DG资源或CG资源，第二上行资源也可以是DG资源或CG资源。且第一上行资源和第二上行资源可以都是CG资源，也可以都是DG资源，或者一个是CG资源，一个是DG资源。
其中，所述重叠部分可以包括第一上行资源和/或第二上行资源在时域上的全部或部分资源。参见图6a-图6b所示，为本申请实施例提供的两种重叠部分，图6a中所述重叠部分包括第一上行资源或第二上行资源在时域上的部分资源，图6b中所述重叠部分包括第一上行资源在时域上的全部资源，或者包括第二上行资源在时域上的部分资源。
本申请实施例中，可以由终端的MAC实体或PHY实体确定第一上行资源的优先级高于第二上行资源的优先级。
若由终端的MAC实体确定第一上行资源的优先级高于第二上行资源的优先级，则终 端的MAC实体可以但不限于采用如下三种方法中的任意一种方法或任意方法的组合确定第一上行资源的优先级高于第二上行资源的优先级。
方法1，终端的MAC实体可以根据第一上行资源与第二上行资源的调度/到达时刻来确定两者的优先级，当确定第一上行资源的调度/到达时刻晚于第二上行资源调度/到达时刻时，即可确定第一上行资源的优先级高于第二上行资源的优先级。
方法2，终端的MAC实体可以根据第一上行资源与第二上行资源的调度命令或配置命令中优先级指示所指示的优先级来确定两者的优先级，当确定第一上行资源的调度命令或配置命令中优先级指示所指示的优先级，高于第二上行资源的调度命令或配置命令中的优先级指示所指示的优先级时，可确定第一上行资源的优先级高于第二上行资源的优先级。例如，假设第一上行资源为CG资源，第二上行资源为DG资源，当终端的MAC实体确定CG资源的配置命令中优先级指示所指示的优先级，高于DG资源的调度命令中的优先级指示所指示的优先级时，可确定第一上行资源的优先级高于第二上行资源的优先级。
方法3，终端的MAC实体可以根据能够在第一上行资源与第二上行资源上进行传输的数据所属逻辑信道(logical channel，LCH)的最高优先级来确定两者的优先级，当确定能够在第一上行资源上传输的数据所属LCH最高优先级，高于能够在第二上行资源上传输的数据所属LCH最高优先级时，可确定第一上行资源的优先级高于第二上行资源的优先级。
若由终端的PHY实体确定第一上行资源的优先级高于第二上行资源的优先级，则终端的PHY实体除了可以采用上述方法1-方法3中任一方法或任意方法的组合来确定之外，还可以采用如下方法4确定，当然，也可以采用方法1-方法4任意组合的方法确定。
方法4，终端的PHY实体可以根据MAC实体发送的第一上行资源与第二上行资源的优先级指示信息确定两者的优先级。例如，当MAC实体确定出第一上行资源的优先级高于第二上行资源的优先级时，可以向PHY实体发送优先级指示信息，该优先级指示信息用于指示第一上行资源的优先级高于第二上行资源的优先级，此时，PHY实体可以根据该优先级指示信息确定第一上行资源的优先级高于第二上行资源的优先级。或者，终端的MAC实体向PHY实体递交MAC PDU或指示PHY进行数据传输时，指示该MAC PDU的优先级信息或该MAC PDU对应的上行传输资源的优先级信息，PHY实体通过比较MAC实体所指示的MAC PDU的优先级信息或上行传输资源的优先级信息，确定哪一个上行传输资源的优先级更高。
可以理解，若将本申请实施例提供的方法应用于图1所示的网络架构，则本申请实施例中的终端为图1中的终端130、网络设备为图1中的RAN110。
步骤102：终端确定在重叠部分采用第一上行资源发送信号时，向网络设备指示针对第二上行资源是否组成MAC PDU或针对第二上行资源是否有数据存储在对应的缓存中。其中，本申请中信号可以包括数据和/或控制信令。
本申请实施例中，针对第二上行资源是否组成MAC PDU，包括针对第二上行资源组成MAC PDU或针对第二上行资源未组成MAC PDU。其中，针对第二上行资源组成的MAC PDU，可以理解为针对第二上行资源生成的MAC PDU，也可以理解为根据第二上行资源生成的MAC PDU，也可以理解为与第二上行资源对应的MAC PDU，也可以理解为与第二上行资源关联的MAC PDU，也可以理解为准备在第二上行资源上传输的MAC PDU，针对第二上行资源未组成MAC PDU的理解与之类似。相应的，针对第二上行资源是否有 数据存储在对应的缓存中，包括针对第二上行资源有数据存储在对应的缓存中或针对第二上行资源没有数据存储在对应的缓存中。其中，针对第二上行资源有数据存储在对应的缓存中，可以理解为有与第二上行资源对应的数据存储在对应的缓存中，针对第二上行资源没有数据存储在对应的缓存中的理解与之类似。示例性地，以与第二上行资源对应的数据为，针对第二上行资源组成的MAC PDU由终端的MAC实体递交到终端的PHY实体后对应的数据为例，针对第二上行资源有数据存储在对应的缓存中，可以理解为针对第二上行资源组成的MAC PDU由终端的MAC实体递交到终端的PHY实体后对应的数据存储在对应的HARQ进程中，或者，也可以理解为针对第二上行资源组成的MAC PDU由终端的MAC实体递交到终端的PHY实体后对应的数据存储在对应的HARQ进程的缓存(buffer)中，或者理解为终端在获取第二上行资源前即存储在对应HARQ进程的缓存中的数据。
以上方法还可以包括终端获取第一上行资源和第二上行资源，其中第一上行资源为DG资源或CG资源时，其获取方式同以上3)的描述，即可以通过下行控制信息获取DG资源，通过RRC信令获取CG资源，或者通过RRC信号和下行控制信息获取CG资源。
本申请实施例中，步骤102对应有如下多种实现方案：
方案1：终端确定在重叠部分采用第一上行资源发送信号时，向网络设备指示针对第二上行资源组成MAC PDU。示例性地，终端确定在重叠部分采用第一上行资源发送信号，且终端确定针对第二上行资源组成MAC PDU时，向网络设备指示针对第二上行资源组成MAC PDU。对于方案1，终端只在针对第二上行资源组成MAC PDU时，才向网络设备指示，对于该方案，网络设备在未收到终端指示的情况下，可以默认为终端针对第二上行资源未组成MAC PDU。

方案3：终端确定在重叠部分采用第一上行资源发送信号时，向网络设备指示针对第二上行资源未组成MAC PDU。示例性地，终端确定在重叠部分采用第一上行资源发送信号，且终端确定针对第二上行资源未组成MAC PDU时，向网络设备指示针对第二上行资源未组成MAC PDU。对于方案3，终端只在针对第二上行资源未组成MAC PDU时，才向网络设备指示，对于该方案，网络设备在未收到终端指示的情况下，可以默认为终端针对第二上行资源组成MAC PDU。
方案4：终端确定在重叠部分采用第一上行资源发送信号时，向网络设备指示针对第二上行资源有数据存储在对应的缓存中。示例性地，终端确定在重叠部分采用第一上行资源发送信号，且终端确定针对第二上行资源有数据存储在对应的缓存中时，向网络设备指示针对第二上行资源有数据存储在对应的缓存中。对于方案4，终端只在针对第二上行资源有数据存储在对应的缓存中时，才向网络设备指示，对于该方案，网络设备在未收到终 端指示的情况下，可以默认为终端针对第二上行资源没有数据存储在对应的缓存中。
方案5：终端确定在重叠部分采用第一上行资源发送信号时，向网络设备指示针对第二上行资源有数据存储在对应的缓存中或针对第二上行资源没有数据存储在对应的缓存中。示例性地，终端确定在重叠部分采用第一上行资源发送信号，且终端确定针对第二上行资源有数据存储在对应的缓存中时，向网络设备指示针对第二上行资源有数据存储在对应的缓存中；或者，终端确定在重叠部分采用第一上行资源发送信号，且终端确定针对第二上行资源没有数据存储在对应的缓存中时，向网络设备指示针对第二上行资源没有数据存储在对应的缓存中。对于方案5，终端不仅在针对第二上行资源有数据存储在对应的缓存中时，向网络设备指示，而且终端在针对第二上行资源没有数据存储在对应的缓存中时，也向网络设备指示，网络设备可根据终端不同的指示确定终端针对第二上行资源是否有数据存储在对应的缓存中。
方案6：终端确定在重叠部分采用第一上行资源发送信号时，向网络设备指示针对第二上行资源没有数据存储在对应的缓存中。示例性地，终端确定在重叠部分采用第一上行资源发送信号，且终端确定针对第二上行资源没有数据存储在对应的缓存中时，向网络设备指示针对第二上行资源没有数据存储在对应的缓存中。对于方案6，终端只在针对第二上行资源没有数据存储在对应的缓存中时，才向网络设备指示，对于该方案，网络设备在未收到终端指示的情况下，可以默认为终端针对第二上行资源有数据存储在对应的缓存中。
方案7：终端确定在重叠部分采用第一上行资源发送信号时，向网络设备指示针对第二上行资源组成MAC PDU或针对第二上行资源有数据存储在对应的缓存中。示例性地，终端确定在重叠部分采用第一上行资源发送信号，且终端确定针对第二上行资源组成MAC PDU时，向网络设备指示针对第二上行资源组成MAC PDU；或者，终端确定在重叠部分采用第一上行资源发送信号，且终端确定针对第二上行资源有数据存储在对应的缓存中时，向网络设备指示针对第二上行资源有数据存储在对应的缓存中。对于方案7，终端只在针对第二上行资源组成MAC PDU或针对第二上行资源有数据存储在对应的缓存中时，才向网络设备指示，对于该方案，网络设备在未收到终端指示的情况下，默认为终端针对第二上行资源未组成MAC PDU或针对第二上行资源没有数据存储在对应的缓存中。
方案8：终端确定在重叠部分采用第一上行资源发送信号时，向网络设备指示针对第二上行资源组成MAC PDU或针对第二上行资源有数据存储在对应的缓存中或针对第二上行资源未组成MAC PDU或针对第二上行资源没有数据存储在对应的缓存中。示例性地，终端确定在重叠部分采用第一上行资源发送信号，且终端确定针对第二上行资源组成MAC PDU时，向网络设备指示针对第二上行资源组成MAC PDU；或者，终端确定在重叠部分采用第一上行资源发送信号，且终端确定针对第二上行资源有数据存储在对应的缓存中时，向网络设备指示针对第二上行资源有数据存储在对应的缓存中；或者，终端确定在重叠部分采用第一上行资源发送信号，且终端确定针对第二上行资源未组成MAC PDU时，向网络设备指示针对第二上行资源未组成MAC PDU；或者，终端确定在重叠部分采用第一上行资源发送信号，且终端确定针对第二上行资源没有数据存储在对应的缓存中时，向网络设备指示针对第二上行资源没有数据存储在对应的缓存中。对于方案8，终端不仅在针对第二上行资源组成MAC PDU或针对第二上行资源有数据存储在对应的缓存中时，向网络设备指示，而且终端在针对第二上行资源未组成MAC PDU或针对第二上行资源没有数据存储在对应的缓存中时，也向网络设备指示，网络设备可根据终端不同的指示确定终端针 对第二上行资源是否组成MAC PDU或针对第二上行资源是否有数据存储在对应的缓存中。
方案9：终端确定在重叠部分采用第一上行资源发送信号时，向网络设备指示针对第二上行资源未组成MAC PDU或针对第二上行资源没有数据存储在对应的缓存中。示例性地，终端确定在重叠部分采用第一上行资源发送信号，且终端确定针对第二上行资源未组成MAC PDU时，向网络设备指示针对第二上行资源未组成MAC PDU；或者，终端确定在重叠部分采用第一上行资源发送信号，且终端确定针对第二上行资源没有数据存储在对应的缓存中时，向网络设备指示针对第二上行资源没有数据存储在对应的缓存中。对于方案9，终端只在针对第二上行资源未组成MAC PDU或针对第二上行资源没有数据存储在对应的缓存中时，才向网络设备指示，对于该方案，网络设备在未收到终端指示的情况下，可以默认为终端针对第二上行资源组成MAC PDU或针对第二上行资源有数据存储在对应的缓存中。
一种可能的实现中，终端确定在重叠部分采用第一上行资源发送信号之前，可以针对第一上行资源组成第一MAC PDU。基于该种实现，终端针对第一上行资源组成第一MAC PDU之后，还可以在重叠部分采用第一上行资源发送第一MAC PDU。需要说明的是，终端除可以在重叠部分采用第一上行资源发送第一MAC PDU之外，还可以在第一上行资源包括的除重叠部分之外的资源上发送第一MAC PDU。例如，以图6a为例，终端除可以在重叠部分采用第一上行资源发送第一MAC PDU之外，还可以在第一上行资源包括的除重叠部分之外的第一部分资源上发送第一MAC PDU，也就是，终端可以在整个第一上行资源上发送第一MAC PDU。
需要说明的是，本申请实施例中，为与针对第一上行资源组成的第一MAC PDU区分，下文中将针对第二上行资源组成的MAC PDU描述为第二MAC PDU。
一种可能的设计中，第一上行资源关联的HARQ进程和第二上行资源关联的HARQ进程不同。通过该设计的方法，可减少网络设备进行无效调度。例如，一些可能的场景中，终端生成的第一上行资源和第二上行资源可能关联相同的HARQ进程，这些场景下，当终端针对第一上行资源和第二上行资源分别组成第一MAC PDU和第二MAC PDU后，终端的MAC实体将第一MAC PDU与第二MAC PDU递交至终端的PHY实体，在终端的PHY层第一MAC PDU与第二MAC PDU需要在相同的HARQ进程的缓存(buffer)中等待发送，此时由于终端针对第二上行资源生成第二MAC PDU，网络设备可能会调度资源进行第二MAC PDU的传输或重传，但是，由于第一MAC PDU与第二MAC PDU需要在相同的HARQ进程的buffer中等待发送，可能会导致第二MAC PDU被第一MAC PDU覆盖，若第二MAC PDU被第一MAC PDU覆盖，则网络设备此次调度便为无效调度。采用该设计的方法，在第一上行资源关联的HARQ进程和第二上行资源关联的HARQ进程不同的情况下，执行本申请提供的方法，可以有效减少网络设备进行无效调度。
步骤103：网络设备根据终端的指示确定针对第二上行资源是否组成第二MAC PDU或针对第二上行资源是否有数据存储在对应的缓存中。
步骤104a：当网络设备确定针对第二上行资源组成第二MAC PDU或针对第二上行资源有数据存储在对应的缓存中时，网络设备调度第二上行资源的重传。示例性地，若网络设备根据终端的指示确定针对第二上行资源组成MAC PDU，则网络设备可以调度资源对该MAC PDU进行传输或重传，若网络设备根据终端的指示确定针对第二上行资源有数据存储在对应的缓存中，则网络设备可以调度资源对该数据进行传输或重传。
步骤104b：当网络设备确定针对第二上行资源未组成第二MAC PDU或针对第二上行资源没有数据存储在对应的缓存中时，网络设备不调度第二上行资源的重传。示例性地，若网络设备根据终端的指示确定针对第二上行资源未组成MAC PDU或针对第二上行资源没有数据存储在对应的缓存中，则网络设备无需调度一块资源对该第二上行资源所关联HARQ进程中缓存的数据进行传输或重传。
针对上行资源在时域上重叠的场景，通过本申请实施例提供的上述方法，终端确定在重叠部分采用优先级较高的上行资源发送信号时，可以向网络设备指示针对优先级较低的上行资源是否组成MAC PDU或针对优先级较低的上行资源是否有数据存储在对应的缓存中，这样，网络设备可以在终端针对优先级较低的上行资源组成MAC PDU或针对优先级较低的上行资源有数据存储在对应的缓存中的情况下，调度资源传输或重传针对优先级较低的上行资源组成的MAC PDU或数据，进而可减少数据丢失，保证用户体验，且采用该方法，网络设备在终端针对优先级较低的上行资源未组成MAC PDU或针对优先级较低的上行资源没有数据存储在对应的缓存中的情况下，无需调度资源对该优先级较低的上行资源所关联HARQ进程中缓存的数据进行传输或重传，进而可节省信令开销，且节省重传资源。
本申请实施例中，终端可以采用显式指示方式或隐式指示方式，向网络设备指示针对第二上行资源是否组成MAC PDU或针对第二上行资源是否有数据存储在对应的缓存中，本申请对于终端采用何种方式指示不做限定。下面详细描述终端如何采用显式指示方式或隐式指示方式向网络设备指示。
第一类，终端采用显式指示方式向网络设备指示针对第二上行资源是否组成MAC PDU或针对第二上行资源是否有数据存储在对应的缓存中。
在显式指示方式中，终端可以向网络设备发送指示信息，通过所述指示信息向网络设备指示针对第二上行资源是否组成MAC PDU或针对第二上行资源是否有数据存储在对应的缓存中。
对于显式指示方式，终端向网络设备发送的所述指示信息可以承载在不同的信息中，例如，可以承载在媒体接入控制元素(MAC control element，MAC CE)中，又例如，也可以承载在所述第一MAC PDU包括的任意MAC子头，又例如，也可以承载在上行控制信息(uplink control information，UCI)中。下面针对不同的显式指示方式进行详细说明。
显式指示方式一，将所述指示信息承载于MAC CE，所述MAC CE可以携带在第一MAC PDU中，当然所述MAC CE也可以携带在其它MAC PDU，本申请不做限定。采用方式一的指示方法，网络设备可以通过接收到的第一MAC PDU中携带的所述MAC CE中承载的所述指示信息，合理调度第二上行资源的重传，在指示信息指示针对第二上行资源组成MAC PDU或针对第二上行资源有数据存储在对应的缓存中时，网络设备调度资源传输或重传针对第二上行资源组成的MAC PDU或数据，进而可减少数据丢失，在指示信息指示针对第二上行资源未组成MAC PDU或针对第二上行资源没有数据存储在对应的缓存中时，网络设备可以不调度资源对第二上行资源所关联HARQ进程中缓存的数据进行传输或重传，进而可节省信令开销，且节省重传资源，从而可提高资源利用率。
需要说明的是，本申请实施例中仅以两块上行资源重叠为例进行说明，当有多块上行资源重叠时，也可以采用本申请提供的方法进行指示。
基于上述显式指示方式一，一种可能的实现方式中，第二上行资源的数量为多个，也 就是与第一上行资源重叠的上行资源的数量有多个，该种情况下，多个第二上行资源中的每个第二上行资源对应的指示信息，可以承载于相同的MAC CE或不同的MAC CE。举例说明，以3块上行资源重叠为例，3块上行资源分别为上行资源A、上行资源B以及上行资源C，其中，上行资源A的优先级高于上行资源B和上行资源C的优先级，假设终端针对上行资源A生成MAC PDU1或针对上行资源A生成的MAC PDU1存储在对应HARQ的缓存中，且，针对上行资源B生成MAC PDU2或针对上行资源B生成的MAC PDU2存储在对应HARQ的缓存中，且，针对上行资源C生成MAC PDU3或针对上行资源C生成的MAC PDU3存储在对应HARQ的缓存中，则终端可以优先发送MAC PDU1，基于该举例，若采用本申请提供的方案7，终端可以针对上行资源B生成指示信息1，该指示信息1用于指示针对上行资源B生成MAC PDU2或针对上行资源B生成的MAC PDU2存储在对应HARQ的缓存中，且，终端可以针对上行资源C生成指示信息2，该指示信息2用于指示针对上行资源C生成MAC PDU3或针对上行资源C生成的MAC PDU3存储在对应HARQ的缓存中，针对该举例，终端可以分别针对上行资源B和上行资源C生成与之对应的MAC CE，例如，终端可以针对上行资源B生成MAC CE1，通过MAC CE1承载指示信息1，并可以针对上行资源C生成MAC CE2，通过MAC CE2承载指示信息2，当然，终端也可以针对上行资源B和上行资源C生成一个MAC CE3，通过MAC CE3承载指示信息1和指示信息2。
基于上述显式指示方式一，承载所述指示信息的MAC CE可以只包括MAC子头，也可以包括MAC子头和负载(payload)。
一种可能的设计中，当承载所述指示信息的MAC CE只包括MAC子头时，所述指示信息位于所述MAC CE的MAC子头。参阅图7所示，当所述指示信息位于所述MAC CE的MAC子头时，所述指示信息可以是所述MAC CE的MAC子头中包括的逻辑信道标识(logical channel identification，LCID)，LCID包括6个比特位，6个比特位可以指示0-63的值，目前LCID包括的6个比特位指示0-32以及52-63已被使用，故本申请可以采用该LCID包括的6个比特位指示33-51中任意值，指示针对第二上行资源是否组成MAC PDU或针对第二上行资源是否有数据存储在对应的缓存中。例如，可以采用LCID包括的6个比特位指示33时，也就是，LCID的6个比特位取值为100001时，指示针对第二上行资源组成MAC PDU或针对第二上行资源有数据存储在对应的缓存中。又例如，可以采用LCID包括的6个比特位指示33时，也就是，LCID的6个比特位取值为100001时，指示针对第二上行资源组成MAC PDU或针对第二上行资源有数据存储在对应的缓存中，并可以采用LCID包括的6个比特位指示34时，也就是，LCID的6个比特位取值为100010时，指示针对第二上行资源未组成MAC PDU或针对第二上行资源没有数据存储在对应的缓存中。
另一种可能的设计中，当承载所述指示信息的MAC CE包括MAC子头和负载(payload)时，所述指示信息可以位于所述MAC CE的MAC子头或所述MAC CE的负载。
其中，当所述指示信息位于MAC CE的负载时，所述指示信息可以是所述MAC CE的负载中的比特位。示例性地，当第二上行资源的数量为一个时，所述指示信息可以是所述MAC CE的负载中的一个比特位，通过该比特位的取值为0或1来指示针对第二上行资源是否组成MAC PDU或针对第二上行资源是否有数据存储在对应的缓存中，例如，当该比特位的取值为1时，可以指示针对第二上行资源组成MAC PDU或针对第二上行资源有 数据存储在对应的缓存中，当该比特位的取值为0时，可以指示针对第二上行资源未组成MAC PDU或针对第二上行资源没有数据存储在对应的缓存中，又例如，当该比特位的取值为0时，可以指示针对第二上行资源组成MAC PDU或针对第二上行资源有数据存储在对应的缓存中，当该比特位的取值为1时，可以指示针对第二上行资源未组成MAC PDU或针对第二上行资源没有数据存储在对应的缓存中。示例性地，当第二上行资源的数量为多个，且将多个第二上行资源中的每个第二上行资源对应的指示信息承载于相同的MAC CE时，所述指示信息可以是所述MAC CE的负载中的多个比特位，通过多个比特位的取值来指示针对第二上行资源是否组成MAC PDU或针对第二上行资源是否有数据存储在对应的缓存中。例如，当第二上行资源的数量为3个，分别为第二上行资源A、第二上行资源B以及第二上行资源C，指示信息可以为所述MAC CE的负载中的3个比特位，分别为比特位A、比特位B以及比特位C，可以通过比特位A的取值指示针对第二上行资源A是否组成MAC PDU或针对第二上行资源A是否有数据存储在对应的缓存中，可以通过比特位B的取值指示针对第二上行资源B是否组成MAC PDU或针对第二上行资源B是否有数据存储在对应的缓存中，可以通过比特位C的取值指示针对第二上行资源C是否组成MAC PDU或针对第二上行资源C是否有数据存储在对应的缓存中。
基于显式指示方式一，一种可能的实现方式中，终端在针对第二上行资源组成MAC PDU或针对第二上行资源有数据存储在对应的缓存中时，向网络设备发送承载指示信息的MAC CE，终端在针对第二上行资源未组成MAC PDU或针对第二上行资源没有数据存储在对应的缓存中时，不向网络设备发送承载指示信息的MAC CE。网络设备可以根据终端是否发送承载指示信息的MAC CE，判断终端针对第二上行资源是否组成MAC PDU或针对第二上行资源是否有数据存储在对应的缓存中，进而合理调度第二上行资源的重传。
基于显式指示方式一，另一种可能的实现方式中，终端在针对第二上行资源组成MAC PDU或针对第二上行资源有数据存储在对应的缓存中时，或者，终端在针对第二上行资源未组成MAC PDU或针对第二上行资源没有数据存储在对应的缓存中时，均向网络设备发送承载指示信息的MAC CE，并可通过该MAC CE的MAC子头中的LCID或MAC CE的负载中的比特位，指示针对第二上行资源是否组成MAC PDU或针对第二上行资源是否有数据存储在对应的缓存中。网络设备可以根据终端发送的MAC CE的MAC子头中的LCID或MAC CE的负载中的比特位的取值/状态，判断终端针对第二上行资源是否组成MAC PDU或针对第二上行资源是否有数据存储在对应的缓存中，进而合理调度第二上行资源的重传。
本申请实施例中，承载指示信息的MAC CE还可以包括如下信息中的一项或多项：
第1项，第二上行资源关联的HARQ进程的标识信息。其中，所述HARQ进程的标识信息可以包括HARQ进程的ID。当第二上行资源的数量为多个，且将多个第二上行资源中的每个第二上行资源对应的指示信息承载于相同的MAC CE时，HARQ进程的标识信息可以包括多个第二上行资源中的每个第二上行资源关联的HARQ进程的ID或多个第二上行资源中的全部HARQ进程从小到大排序或从大到小排序后对应的索引值。当第二上行资源的数量为多个，且将多个第二上行资源中的每个第二上行资源对应的指示信息承载于不同的MAC CE时，每个第二上行资源关联的HARQ进程的标识信息可以包括该HARQ进程的ID，或该HARQ进程在多个第二上行资源中的全部HARQ进程从小到大排序或从大到小排序后对应的索引值。
举例说明，以3块上行资源重叠为例，3块上行资源分别为上行资源A、上行资源B以及上行资源C，其中，上行资源A的优先级高于上行资源B和上行资源C的优先级，可以理解为在该举例中上行资源A为本申请中的第一上行资源，上行资源B和上行资源C为本申请中的第二上行资源，相当于第二上行资源的数量为2，假设上行资源B和上行资源C关联的HARQ进程的ID分别为6、8，则上行资源B和上行资源C关联的HARQ进程从小到大排序后对应的索引值分别为1、2，终端可以在针对上行资源B生成的MAC CE中包括上行资源B关联的HARQ进程对应的索引值1，终端也可以在针对上行资源C生成的MAC CE中包括上行资源C关联的HARQ进程对应的索引值2，当然，终端也可以在针对上行资源B和上行资源C生成的MAC CE中，包括上行资源B关联的HARQ进程对应的索引值1以及上行资源C关联的HARQ进程对应的索引值2。
第2项，第二上行资源的位置信息。例如，所述位置信息可以包括第二上行资源的起始时刻的时间点，如系统帧号(system frame number，SFN)和/或时隙(slot)和/或符号(symbol)值等，即可以包括SFN，时隙或符号，或者包括SFN和时隙，或者包括SFN和符号，或者包括SFN，时隙和符号。当第二上行资源的数量为多个，且将多个第二上行资源中的每个第二上行资源对应的指示信息承载于相同的MAC CE时，第二上行资源的位置信息可以包括多个第二上行资源中的每个第二上行资源的起始时刻的时间点，或多个第二上行资源中的每个第二上行资源的起始时刻按时间的先后顺序排序后对应的索引值。当第二上行资源的数量为多个，且将多个第二上行资源中的每个第二上行资源对应的指示信息承载于不同的MAC CE时，每个第二上行资源的位置信息包括该第二上行资源的起始时刻的时间点，或该第二上行资源的起始时刻的时间点在多个第二上行资源的起始时刻按时间的先后顺序排序后对应的索引值。
第3项，第二MAC PDU中最高优先级的逻辑信道(logical channel，LCH)的标识或优先级。
第4项，第二MAC PDU中最高优先级的LCH关联的SR信息。例如所述SR信息可以包括SR配置ID等信息。
基于上述显式指示方式一，可以预定义承载指示信息的MAC CE的优先级，也可以通过RRC信令/SIB信令配置所述MAC CE的优先级。例如，可以预定义所述MAC CE的优先级高于任意LCH的数据的优先级，但低于现有MAC CE的优先级。又例如，可以通过RRC信令/SIB信令配置所述MAC CE的优先级高于部分/全部现有MAC CE的优先级。又例如，可以预定义或通过RRC信令/SIB信令配置所述MAC CE的优先级高于部分LCH的数据的优先级。
下面以一个例子对上述显式指示方式一进行说明，请参见图8a-图8b所示，为本申请实施例提供的指示方式示意图。图8a和图8b中以为终端配置了两块在时域上有重叠的上行资源为例示意，两块在时域上有重叠的上行资源分别为上行资源1和上行资源2，其中，上行资源1和上行资源2均可以为CG资源或DG资源，假设上行资源2的优先级高于上行资源1的优先级，上行资源1用于新传或者重传，上行资源2用于新传，图8a和图8b中以上行资源2的起始时刻晚于上行资源1的起始时刻为例示意，实际中上行资源2的起始时刻也可以与上行资源1的起始时刻相同或者早于上行资源1的起始时刻。以下分别针对图8a和图8b所示的两种场景进行说明。
图8a中以终端的MAC实体执行本申请提供的方法为例示意说明。一种可能的实现中， 终端的MAC实体在处理上行资源2的过程中，若确定上行资源2的优先级高于上行资源1的优先级，且终端针对上行资源1组成MAC PDU或终端针对上行资源1组成的MAC PDU对应的数据存储在对应的HARQ进程中或终端针对上行资源1组成的MAC PDU对应的数据存储在对应的HARQ进程的缓存(buffer)中，且上行资源1关联的HARQ进程和上行资源2关联的HARQ进程不同，则该终端可以触发生成MAC CE，通过该MAC CE承载指示信息，该指示信息用于指示针对上行资源1组成MAC PDU或针对上行资源1有数据存储在对应的缓存中，进而终端可将承载所述指示信息的MAC CE携带在针对上行资源2生成的MAC PDU中发送至网络设备。另一种可能的实现中，终端的MAC实体在处理上行资源2的过程中，若确定上行资源2的优先级高于上行资源1的优先级，且终端针对上行资源1组成MAC PDU，且上行资源1关联的HARQ进程和上行资源2关联的HARQ进程相同，则该终端的MAC实体可以将上行资源1对应的MAC PDU中的部分/全部MAC CE(例如BSR MAC CE)重建到针对上行资源2生成的MAC PDU中，这样，终端可将上行资源1对应的MAC PDU中的MAC CE通过上行资源2对应的MAC PDU发送至网络设备，终端无需再向网络设备发送指示信息，网络设备也无需再调度上行资源1的重传，可节省信令开销。
图8b中以终端的MAC实体执行本申请提供的方法为例示意说明。终端的MAC实体在处理上行资源2的过程中，若确定上行资源2的优先级高于上行资源1的优先级，且终端针对上行资源1未组成MAC PDU或终端针对上行资源1组成的MAC PDU对应的数据未存储在对应的HARQ进程中或终端针对上行资源1组成的MAC PDU对应的数据未存储在对应的HARQ进程的缓存(buffer)中，则该终端可以触发生成MAC CE，通过该MAC CE承载指示信息，该指示信息用于指示针对上行资源1未组成MAC PDU或针对上行资源1没有数据存储在对应的缓存中，进而终端可将承载所述指示信息的MAC CE携带在针对上行资源2生成的MAC PDU中发送至网络设备。
其中，图8a和图8b中针对上行资源1生成的MAC CE中携带的内容，以及MAC CE的优先级配置可参见上述显式指示方式一中的描述，此处不再赘述。
需要说明的是，针对上述图8a和图8b的场景，如果上行资源1被终端的MAC实体主动忽略，如MAC实体在处理上行资源1时，已知后续有上行资源2且可以传输优先级更高的数据，则可以主动清空上行资源1关联的HARQ进程的缓存中存储的数据。
显式指示方式二，将第一MAC PDU的任意MAC子头的比特位作为指示信息。例如，可将第一MAC PDU的任意MAC子头中的R比特位(预留比特位)作为指示信息，可以理解为，将第一MAC PDU的任意MAC子头中的R比特位设置为用于指示针对第二上行资源是否组成MAC PDU或针对第二上行资源是否有数据存储在对应的缓存中的指示位。示例性地，可以将第一MAC PDU包括的第一个MAC子头中的R比特位设置为指示位。参阅图9a所示，其为一种可能的第一个MAC子头示意图，本申请可采用图9a中R比特位的取值为0或1来指示针对第二上行资源是否组成MAC PDU或针对第二上行资源是否有数据存储在对应的缓存中。参阅图9b所示，其为另一种可能的第一MAC子头示意图，本申请可采用图9b中R比特位的取值为0或1来指示针对第二上行资源是否组成MAC PDU或针对第二上行资源是否有数据存储在对应的缓存中。参阅图9c所示，其为又一种可能的第一MAC子头示意图，本申请可采用图9c中第一个R比特位或第二个R比特位的取值为0或1来指示针对第二上行资源是否组成MAC PDU或针对第二上行资源是否有 数据存储在对应的缓存中。例如，当R比特位的取值为1时，可以指示针对第二上行资源组成MAC PDU或针对第二上行资源有数据存储在对应的缓存中，当R比特位的取值为0时，可以指示针对第二上行资源未组成MAC PDU或针对第二上行资源没有数据存储在对应的缓存中，又例如，当R比特位的取值为0时，可以指示针对第二上行资源组成MAC PDU或针对第二上行资源有数据存储在对应的缓存中，当R比特位的取值为1时，可以指示针对第二上行资源未组成MAC PDU或针对第二上行资源没有数据存储在对应的缓存中。
采用显式指示方式二的指示方法，网络设备可以通过终端发送的第一MAC PDU中MAC子头包括的指示位，判断终端针对第二上行资源是否组成MAC PDU或针对第二上行资源是否有数据存储在对应的缓存中，进而可合理调度第二上行资源的重传。
下面以一个例子对上述显式指示方式二进行说明，请参见图10a-图10b所示，为本申请实施例提供的指示方式示意图。图10a和图10b中以为终端配置了两块在时域上有重叠的上行资源为例示意，两块在时域上有重叠的上行资源分别为上行资源1和上行资源2，其中，上行资源1和上行资源2均可以为CG资源或DG资源，假设上行资源2的优先级高于上行资源1的优先级，上行资源1用于新传或者重传，上行资源2用于新传，图10a和图10b中以上行资源2的起始时刻晚于上行资源1的起始时刻为例示意，实际中上行资源2的起始时刻也可以与上行资源1的起始时刻相同或者早于上行资源1的起始时刻。以下分别针对图10a和图10b所示的两种场景进行说明。
图10a中以终端的MAC实体执行本申请提供的方法为例示意说明。终端的MAC实体在处理上行资源2的过程中，若确定上行资源2的优先级高于上行资源1的优先级，且终端针对上行资源1组成MAC PDU或终端针对上行资源1组成的MAC PDU对应的数据存储在对应的HARQ进程中或终端针对上行资源1组成的MAC PDU对应的数据存储在对应的HARQ进程的缓存(buffer)中，且上行资源1关联的HARQ进程和上行资源2关联的HARQ进程不同，则该终端可以将针对上行资源2生成的MAC PDU包括的任意一个MAC子头中的R比特位设置为1或0，用于指示针对上行资源1组成MAC PDU或针对上行资源1有数据存储在对应的缓存中，网络设备接收到终端发送的针对上行资源2生成的MAC PDU后，可根据该MAC PDU中MAC子头包括的R比特位的取值，决策调度上行资源1的重传。
图10b中以终端的MAC实体执行本申请提供的方法为例示意说明。终端的MAC实体在处理上行资源2的过程中，若确定上行资源2的优先级高于上行资源1的优先级，且终端针对上行资源1未组成MAC PDU或终端针对上行资源1组成的MAC PDU对应的数据未存储在对应的HARQ进程中或终端针对上行资源1组成的MAC PDU对应的数据未存储在对应的HARQ进程的缓存(buffer)中，则该终端可以将针对上行资源2生成的MAC PDU包括的任意一个MAC子头中的R比特位设置为0或1，用于指示针对上行资源1未组成MAC PDU或针对上行资源1没有数据存储在对应的缓存中，网络设备接收到终端发送的针对上行资源2生成的MAC PDU后，可根据该MAC PDU中MAC子头包括的R比特位的取值，决策不调度上行资源1的重传。
显式指示方式三，将所述指示信息承载于上行控制信息(uplink control information，UCI)。
基于上述显式指示方式三，一种可能的实现方式中，终端在针对第二上行资源组成MAC PDU或针对第二上行资源有数据存储在对应的缓存中时，向网络设备发送UCI，终 端在针对第二上行资源未组成MAC PDU或针对第二上行资源没有数据存储在对应的缓存中时，不向网络设备发送UCI，则网络设备可根据终端是否发送UCI，判断终端针对第二上行资源是否组成MAC PDU或针对第二上行资源是否有数据存储在对应的缓存中，进而合理调度第二上行资源的重传。
基于上述显式指示方式三，另一种可能的实现方式中，终端在针对第二上行资源组成MAC PDU或针对第二上行资源有数据存储在对应的缓存中时，或者，终端在针对第二上行资源未组成MAC PDU或针对第二上行资源没有数据存储在对应的缓存中时，均向网络设备发送UCI，并在UCI中包括用于指示针对第二上行资源是否组成MAC PDU或针对第二上行资源是否有数据存储在对应的缓存中的指示位，通过该指示位的取值指示针对第二上行资源是否组成MAC PDU或针对第二上行资源是否有数据存储在对应的缓存中。例如，以该指示位为一个比特位为例，当该比特位的取值为1时，可以用于指示针对第二上行资源组成MAC PDU或针对第二上行资源有数据存储在对应的缓存中，当该比特位的取值为0时，可以用于指示针对第二上行资源未组成MAC PDU或针对第二上行资源没有数据存储在对应的缓存中。基于该种实现，网络设备可根据UCI中指示位的取值/状态，判断终端针对第二上行资源是否组成MAC PDU或针对第二上行资源是否有数据存储在对应的缓存中，进而合理调度第二上行资源的重传。
其中，基于上述显式指示方式三，所述UCI除可以包括所述指示位之外，还可以包括如下信息中的一项或多项：
第1项，第二上行资源关联的HARQ进程的标识信息。
第2项，第二上行资源的位置信息。例如，所述位置信息可以包括第二上行资源的起始时刻的时间点，如SFN和/或slot和/或symbol值等。
第3项，第二MAC PDU中最高优先级的LCH的标识或优先级。
第4项，第二MAC PDU中最高优先级的LCH关联的SR信息。例如所述SR信息可以包括SR配置ID等信息。
需要说明的是，关于上述第1项-第4项的详细内容，可参见显式指示方式一中的相关描述，此处不再赘述。
基于上述显式指示方式三，终端可采用如下两种方式向网络设备发送UCI：
方式1：终端的MAC实体指示PHY实体向网络设备发送UCI。
方式2：终端的PHY实体向网络设备发送UCI。
基于上述显式指示方式三，一种可能的实现方式中，UCI参数，例如发送该UCI的时频资源位置或格式等参数，可以与第一上行资源或第二上行资源关联。示例性地，以UCI参数为发送该UCI的时频资源位置为例，当第一上行资源或第二上行资源为CG资源时，UCI的时频资源位置可以由RRC信令配置；当第一上行资源或第二上行资源为DG资源时，UCI的时频资源位置可以由RRC信令配置和/或DCI进行指示。例如，当第一上行资源为DG资源时，可以在分配第一上行资源的DCI中指示UCI的时频资源位置；或者可以通过RRC信令配置时频资源位置集合，并在分配第一上行资源的DCI中指示时频资源位置集合中的一个时频资源位置，作为UCI的时频资源位置。又例如，当第二上行资源为DG资源时，可以在分配第二上行资源的DCI中指示UCI的时频资源位置；或者可以通过RRC信令配置时频资源位置集合，并在分配第二上行资源的DCI中指示时频资源位置集合中的一个时频资源位置，作为UCI的时频资源位置。基于该种实现方式，网络设备可以通过在与 上行资源相关的位置上是否接收到UCI信令，或者接收到的UCI信令中的指示位的取值/状态，判断终端针对第二上行资源是否组成MAC PDU或针对第二上行资源是否有数据存储在对应的缓存中，进而合理调度第二上行资源的重传。例如，以UCI参数和第一上行资源相关联为例进行说明，当终端针对第二上行资源组成MAC PDU或针对第二上行资源有数据存储在对应的缓存中，终端根据第一上行资源确定相应的UCI参数，如第一上行资源为CG资源，则由配置该CG的RRC信令确定UCI的时频资源位置等参数，并在相应的资源上向网络设备发送UCI；如果第一上行资源为DG资源，且UCI时频资源位置等参数由分配第一上行资源的DCI指示，则根据DCI中指示信息确定发送UCI的时频资源位置等。又例如以UCI参数和第二上行资源相关联为例进行说明，当终端针对第二上行资源组成MAC PDU或针对第二上行资源有数据存储在对应的缓存中，终端根据第二上行资源确定相应的UCI参数，如第二上行资源为CG资源，则由配置该CG的RRC信令确定UCI的时频资源位置等参数，并在相应的资源上向网络设备发送UCI；如果第二上行资源为DG资源，且UCI时频资源位置等参数由分配第二上行资源的DCI指示，则根据DCI中指示信息确定发送UCI的时频资源位置等。在本实施例中，发送UCI的时域/频域资源位置，可以由终端根据第一上行资源或第二上行资源的时域/频域资源位置和一定方式推算得到，例如发送UCI的时域位置可以和第一上行资源的时域位置存在固定时间间隔，发送UCI的时域位置也可以第二上行资源的时域位置存在固定时间间隔，发送UCI的频域位置可以和第一上行资源的频域位置存在固定函数关系，发送UCI的频域位置也可以和第二上行资源的频域位置存在固定函数关系。
下面以一个例子对上述显式指示方式三进行说明，请参见图11所示，为本申请实施例提供的指示方式示意图。图11中以为终端配置了两块在时域上有重叠的上行资源为例示意，两块在时域上有重叠的上行资源分别为上行资源1和上行资源2，其中，上行资源1和上行资源2均可以为CG资源或DG资源，假设上行资源2的优先级高于上行资源1的优先级，上行资源1用于新传或者重传，上行资源2用于新传或者重传，图11中以上行资源2的起始时刻晚于上行资源1的起始时刻为例示意，实际中上行资源2的起始时刻也可以与上行资源1的起始时刻相同或者早于上行资源1的起始时刻。以下针对图11所示的场景进行说明。
图11中以终端的MAC实体执行本申请提供的方法为例示意说明。终端的MAC实体在处理上行资源2的过程中，若确定上行资源2的优先级高于上行资源1的优先级，且终端针对上行资源1组成MAC PDU或终端针对上行资源1组成的MAC PDU对应的数据存储在对应的HARQ进程中或终端针对上行资源1组成的MAC PDU对应的数据存储在对应的HARQ进程的缓存(buffer)中，且上行资源1关联的HARQ进程和上行资源2关联的HARQ进程不同，则该终端可以向网络设备发送承载指示信息的UCI，此外，终端在针对上行资源1未组成MAC PDU或针对上行资源1没有数据存储在对应的缓存中时，不向网络设备发送UCI，则网络设备可根据终端是否发送UCI，判断终端针对上行资源1是否组成MAC PDU或针对上行资源1是否有数据存储在对应的缓存中，进而合理调度上行资源1的重传。这里，可以是由MAC实体指示PHY实体发送UCI。
需要说明的是，上述显式指示方式三除可以用于同一终端的上行资源重叠的场景外，还可以用于不同终端之间的上行资源抢占场景。下面详细描述终端间的上行资源抢占场景中存在的问题，以及采用本申请实施例提供的上述显式指示方式三如何解决该问题。
以两个终端之间的上行资源抢占为例，假设网络设备为终端1配置了上行资源1，该上行资源可以是CG资源或DG资源，若此时网络设备检测到终端2有更紧急或更高优先级的上行数据需要传输，则网络设备可以通过指示信令指示终端1不在上行资源1上进行上行传输，并通知终端2使用上行资源1进行上行传输，此时可以理解为终端1的上行资源1被终端2抢占。在该过程中，终端1对于上行资源1的处理有如下三种情形：
第一种情形，针对上行资源1终端1没有合适的待传输数据，准备skip该上行资源1。
第二种情形，终端1在处理上行资源1之前收到了网络设备发送的指示信令，指示终端1不在上行资源1上进行上行传输，此时，终端1的MAC实体可忽略上行资源1。
第三种情形，终端1针对上行资源1组成MAC PDU并递交到PHY实体，PHY实体收到网络设备发送的所述指示信令后放弃上行资源1的传输。
针对上述三种情形，网络设备在上行资源1上均接收不到信号。目前针对上述场景，一种处理方式中网络设备默认终端1启用了跳过(skip)机制，当网络设备在上行资源1上接收不到信号时，认为终端1在该上行资源1上没有合适的信号传输，故不会调度该上行资源1的重传，而实际中，终端1可能并没有skip该上行资源1，而是针对该上行资源1已组成数据包但是上行资源1被终端2抢占，故无法发送针对上行资源1组成的数据包，这种情况下，若网络设备不调度该上行资源1的重传，可能会导致数据丢失，进而影响用户体验。另一种处理方式中，针对上述场景网络设备被配置为一直调度该上行资源1的重传，而实际中，终端1可能skip该上行资源1或忽略该上行资源1，也就是，终端可能未针对上行资源1组成MAC PDU或者没有针对上行资源1的数据存储在对应的缓存中，这种情况下，若网络设备调度该上行资源1的重传，则会增加信令开销，且浪费重传资源。
鉴于上述存在的问题，可采用本申请中显式指示方式三的方法解决。
基于上述显式指示方式三，终端1可通过向网络设备发送UCI，指示针对上行资源1是否组成MAC PDU或针对上行资源1是否有数据存储在对应的缓存中。一种可能的实现方式中，当终端1接收到来自网络设备的抢占指示信令，且终端1针对上行资源1组成MAC PDU或针对上行资源1有数据存储在对应的缓存中时，向网络设备发送UCI。其中，本申请中抢占指示信令用于指示终端1不在上行资源1上进行上行传输，可以理解为，抢占指示信令用于指示上行资源1被抢占。当终端1接收到来自网络设备的抢占指示信令，且终端1在针对上行资源1未组成MAC PDU或针对上行资源1没有数据存储在对应的缓存中时，不向网络设备发送UCI，则网络设备可根据终端1是否发送UCI，判断终端1针对上行资源1是否组成MAC PDU或针对上行资源1是否有数据存储在对应的缓存中，进而合理调度上行资源1的重传。另一种可能的实现方式中，终端1在针对上行资源1组成MAC PDU或针对上行资源1有数据存储在对应的缓存中时，或者，终端1在针对上行资源1未组成MAC PDU或针对上行资源1没有数据存储在对应的缓存中时，均向网络设备发送UCI，并在UCI中包括用于指示针对上行资源1是否组成MAC PDU或针对上行资源1是否有数据存储在对应的缓存中的指示位，通过该指示位的取值指示针对上行资源1是否组成MAC PDU或针对上行资源1是否有数据存储在对应的缓存中。例如，以该指示位为一个比特位为例，当该比特位的取值为1时，可以用于指示针对上行资源1组成MAC PDU或针对上行资源1有数据存储在对应的缓存中，当该比特位的取值为0时，可以用于指示针对上行资源1未组成MAC PDU或针对上行资源1没有数据存储在对应的缓存中。基于该种实现，网络设备可根据UCI中指示位的取值/状态，判断终端1针对上行资源1 是否组成MAC PDU或针对上行资源1是否有数据存储在对应的缓存中，进而合理调度上行资源1的重传。
其中，针对上行资源1有数据存储在对应的缓存中，可以理解为针对上行资源1组成的MAC PDU对应的数据存储在对应的HARQ进程中或针对上行资源1组成的MAC PDU对应的数据存储在对应的HARQ进程的缓存(buffer)中。
基于上述举例，终端1可采用如下两种方式向网络设备发送UCI：
方式1：终端1的PHY实体将网络设备发送的抢占指示信令通知终端1的MAC实体，进而由终端1的MAC实体指示PHY实体向网络设备发送UCI。
方式2：终端1的PHY实体收到网络设备发送的抢占指示信令后，由终端1的PHY实体向网络设备发送UCI。
一种可能的实现方式中，UCI参数，例如发送该UCI的时频资源位置或格式等参数，可以与上行资源1关联。示例性地，以UCI参数为发送该UCI的时频资源位置为例，当上行资源1为CG资源时，UCI的时频资源位置可以由RRC信令配置；当上行资源1为DG时，UCI的时频资源位置可以由RRC信令配置和/或DCI进行指示。可以通过分配上行资源1的DCI指示UCI的时频资源位置，或者在网络设备发送的抢占指示信令中指示UCI的时频资源位置；或者当上行资源1是DG资源时，可以通过RRC配置该UCI时频资源可选位置的集合，并通过分配上行资源1的DCI，或者网络设备发送的抢占指示信令从UCI时频资源可选位置的集合中指示一个具体的时频资源位置。可选的，在本实施例中，发送UCI的时域/频域资源位置可以由终端根据第一上行资源的时域/频域位置和一定方式推算得到，例如发送UCI的时域位置和第一上行资源的时域位置可以存在固定时间间隔，发送UCI的频域位置可以和第一上行资源的频域位置存在固定函数关系，发送UCI的频域位置也可以和第二上行资源的频域位置存在固定函数关系。
上述举例中，上行资源1被终端2抢占，则在被抢占的资源部分可以不进行数据发送，或者降低功率进行数据发送。在该场景中，如果上行资源1被MAC实体主动忽略，如MAC实体在处理上行资源1之前就收到PHY实体指示上行资源1被终端2抢占，则可以主动清空上行资源1关联的HARQ进程中的数据。
第二类，终端采用隐式指示方式向网络设备指示针对第二上行资源是否组成MAC PDU或针对第二上行资源是否有数据存储在对应的缓存中。
在隐式指示方式中，终端可以采用在第一上行资源上传输的信息向网络设备指示针对第二上行资源是否组成MAC PDU或针对第二上行资源是否有数据存储在对应的缓存中；或者，终端可以采用第一MAC PDU的传输方式，向网络设备指示针对第二上行资源是否组成MAC PDU或针对第二上行资源是否有数据存储在对应的缓存中。
基于上述隐式指示方式，第一上行资源上传输的信息例如可以包括解调参考信号(demodulation reference signal，DMRS)，即，可以通过第一上行资源上传输的DMRS指示针对第二上行资源是否组成MAC PDU或针对第二上行资源是否有数据存储在对应的缓存中。示例性地，网络设备可以通过RRC信令为终端配置两类DMRS，或者为终端预先定义两类DMRS，例如两类DMRS分别为DMRS类型1和DMRS类型2，每类DMRS中可以包含至少一个DMRS。当终端在第一上行资源上传输DMRS类型1包括的DMRS时，指示针对第二上行资源组成MAC PDU或针对第二上行资源有数据存储在对应的缓存中，当终端在第一上行资源上传输DMRS类型2包括的DMRS时，指示针对第二上行资源未 组成MAC PDU或针对第二上行资源没有数据存储在对应的缓存中。
基于上述隐式指示方式，第一MAC PDU的传输方式例如可以包括传输第一MAC PDU所采用的调制方式或加扰方式，即，可以通过第一MAC PDU的调制方式或加扰方式指示针对第二上行资源是否组成MAC PDU或针对第二上行资源是否有数据存储在对应的缓存中。示例性地，网络设备可以通过RRC信令为终端配置两类无线网络临时标识(radio network temporary identifier，RNTI)，或者为终端预先定义两类RNTI，例如两类RNTI分别为RNTI类型1和RNTI类型2，每类RNTI中可以包含至少一个RNTI。当终端采用RNTI类型1包括的RNTI对第一上行资源进行加扰时，指示针对第二上行资源组成MAC PDU或针对第二上行资源有数据存储在对应的缓存中，当终端采用RNTI类型2包括的RNTI对第一上行资源进行加扰时，指示针对第二上行资源未组成MAC PDU或针对第二上行资源没有数据存储在对应的缓存中。示例性地，网络设备可以通过RRC信令为终端配置两类调制编码策略(modulation and coding scheme，MCS)，或者为终端预先定义两类MCS，例如两类MCS分别为MCS类型1和MCS类型2，每类MCS中可以包含至少一个MCS。当终端采用MCS类型1包括的MCS对第一上行资源进行调制时，指示针对第二上行资源组成MAC PDU或针对第二上行资源有数据存储在对应的缓存中，当终端采用MCS类型2包括的MCS对第一上行资源进行调制时，指示针对第二上行资源未组成MAC PDU或针对第二上行资源没有数据存储在对应的缓存中。
下面以一个例子对上述隐式指示方式进行说明，请参见图12所示，为本申请实施例提供的指示方式示意图。图12中以为终端配置了两块在时域上有重叠的上行资源为例示意，两块在时域上有重叠的上行资源分别为上行资源1和上行资源2，其中，上行资源1和上行资源2均可以为CG资源或DG资源，假设上行资源2的优先级高于上行资源1的优先级，上行资源1用于新传或者重传，上行资源2用于新传或者重传，图12中以上行资源2的起始时刻晚于上行资源1的起始时刻为例示意，实际中上行资源2的起始时刻也可以与上行资源1的起始时刻相同或者早于上行资源1的起始时刻。以下针对图12所示的场景对隐式指示方式进行说明。
图12中以终端的MAC实体执行本申请提供的方法为例示意说明。终端的MAC实体在处理上行资源2的过程中，若确定上行资源2的优先级高于上行资源1的优先级，且终端针对上行资源1组成MAC PDU或终端针对上行资源1组成的MAC PDU对应的数据存储在对应的HARQ进程中或终端针对上行资源1组成的MAC PDU对应的数据存储在对应的HARQ进程的缓存(buffer)中，且上行资源1关联的HARQ进程和上行资源2关联的HARQ进程不同，则该终端的MAC实体指示PHY实体通过DMRS类型1进行上行资源2的上行传输，其他情形下，终端使用DMRS类型2进行上行资源2的上行传输。基于该种实现，网络设备可根据上行资源2上传输的DMRS类型，判断终端针对上行资源1是否组成MAC PDU或针对上行资源1是否有数据存储在对应的缓存中，进而合理调度上行资源1的重传。
可选的，也可以由终端的PHY实体执行该方法，当终端的PHY实体确定上行资源2的优先级高于上行资源1的优先级时，通过DMRS类型1进行上行资源1的上行传输。
鉴于上行资源在时域上重叠的场景中无法合理调度上行资源的重传，本申请实施例提供另一种通信方法，在该方法中，针对上行资源在时域上重叠的场景，终端确定在重叠部 分采用优先级较高的上行资源发送信号时，可以利用下个周期到达的资源对优先级较低的上行资源所组的MAC PDU进行传输，可以减少数据包丢失，且采用该方法，无需终端通知网络设备调度新的资源，可节省信令开销。
请参考图13，其为本申请实施例提供的另一种通信方法的实施流程图。参阅图13所示，该方法包括：
步骤201：终端确定在时域上有重叠部分的第一上行资源和第二上行资源中，第一上行资源的优先级高于第二上行资源的优先级。
步骤202：终端在重叠部分采用第一上行资源向网络设备发送信号。
步骤203：终端在第三上行资源上向网络设备发送针对第二上行资源生成的数据包。其中，第三上行资源为在第二上行资源之后到达的上行资源，第三上行资源与第二上行资源关联相同的HARQ进程，且，终端针对第三上行资源未生成数据包。
一种可能的实现方式中，第三上行资源和第二上行资源为配置授权资源不同周期到达的资源。
一种可能的实现方式中，第一上行资源与第二上行资源关联不同的HARQ进程。
下面以一个例子对上述图13中的方法进行说明，请参见图14所示，为本申请实施例提供的数据传输示意图。图14中以为终端配置了两块在时域上有重叠的上行资源为例示意，两块在时域上有重叠的上行资源分别为上行资源1和上行资源2，其中，上行资源2可以为CG资源或DG资源，上行资源1为CG资源，假设上行资源2的优先级高于上行资源1的优先级，上行资源1用于新传，上行资源2用于新传或者重传，图14中以上行资源2的起始时刻晚于上行资源1的起始时刻为例示意，实际中上行资源2的起始时刻也可以与上行资源1的起始时刻相同或者早于上行资源1的起始时刻。以下针对图14所示的场景进行说明。
图14中终端在处理上行资源2的过程中，若确定上行资源2的优先级高于上行资源1的优先级，且终端针对上行资源1组成MAC PDU或终端针对上行资源1组成的MAC PDU对应的数据存储在对应的HARQ进程中或终端针对上行资源1组成的MAC PDU对应的数据存储在对应的HARQ进程的缓存(buffer)中，且上行资源1关联的HARQ进程和上行资源2关联的HARQ进程不同，终端可以在重叠部分采用上行资源2向网络设备发送数据包，并在下一个与上行资源1关联到相同HARQ进程的CG资源(记为上行资源3)到达时，若终端针对该上行资源3没有合适的数据传输，准备skip该上行资源3，此时终端可采用上行资源3向网络设备发送针对上行资源1生成的数据包。
