Description

一种通信方法及通信装置 技术领域
本申请涉及通信领域，尤其涉及一种通信方法及通信装置。
背景技术
当终端在进行基于边链路(sidelink，SL)的车辆与其他设备通信(vehicle to everything，V2X)通信时，可以使用网络设备配置的相关资源进行数据传输。其中，网络设备配置的资源可以是通过配置授权(configured grant，CG)的方法配置的资源，也可以是通过半静态/半永久调度(Semi-Persistent Scheduling，SPS)的方法配置的资源。可将通过CG的方法配置的资源称为CG资源，将通过SPS的方法配置的资源称为SPS资源。
其中，网络设备为终端配置的资源(如上述CG资源或SPS资源)可以分为两类：配置后立即生效的资源以及配置后还需要激活才可使用的资源。示例性的，以网络设备为终端配置的资源为CG资源进行说明。CG资源根据网络设备配置方式的不同分为两类：一类是网络设备通过无线资源控制(Radio Resource Control，RRC)信令配置CG资源相关的所有参数，在完成所有参数的配置后，该CG资源立即生效。终端可以直接使用该CG资源进行通信。即这类CG资源被配置添加(add)后立即生效，如可称为第一类CG资源。另一类则是网络设备通过RRC信令配置CG资源相关的部分参数，完成部分参数的配置后，CG资源不直接生效，需要网络设备使用物理下行控制信息(Downlink Control Information，DCI)通过物理下行控制信道(Physical Downlink Control Channel，PDCCH)配置该CG资源的其他参数，完成对该CG资源的激活(active)后，该CG资源才会生效，用于终端的通信。即这类CG资源配置后还需要激活才可使用，如可称为第二类CG资源。
网络设备除了可以为终端配置资源外，还可以对为终端配置的资源进行处理。示例性的，以为终端配置的资源是CG资源为例，针对上述第一类CG资源，网络设备可以通过重配置消息对配置给终端的CG资源进行删除(release)处理。针对上述第二类CG资源，网络设备可以通过DCI对配置给终端的CG资源进行去激活(deactive)处理。类似于网络设备对CG资源的处理，网络设备也可以通过上述两种方法实现对配置给终端的SPS资源进行相应处理。
可以理解的是，上述对终端资源的管理均是由网络设备完成的。而由于在SL通信中，大多是数据通信都发生在终端之间，因此，网络设备并不知晓当前配置给终端的资源的使用情况。这可能会造成一些不良后果。例如，如果已经配置给终端的资源被闲置，那么就会造成资源的浪费。
发明内容
本申请实施例提供一种通信方法及装置，至少能够使网络设备高效地对配置给终 端的资源进行相应处理，以避免资源的浪费。
为达到上述目的，本申请实施例提供如下技术方案：
第一方面，本申请提供一种通信方法，终端通过物理上行控制信道向网络设备发送第一指示信息，该第一指示信息用于指示处理第一传输资源，该第一传输资源是网络设备为终端配置的，用于进行边链路SL通信的传输资源。示例性的，上述处理可以包括删除或去激活。

具体实施方式
为了明确实施例说明中的技术方案，以下对本申请实施例涉及的名词进行解释：
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，是一种向用户提供语音/数据连通性的设备。例如，具有无线连接功能的手持式设备、或车载设备等。目前，一些终端的举例为：车载电脑、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、或智慧家庭(smart home)中的无线终端等。
2)、通用移动通信网络(Universal Mobile Telecommunications System，UMTS)是由第三代合作伙伴计划(The 3rd Generation Partnership Project，3GPP)组织制定的3G移动通信技术标准。通用移动通信技术的长期演进(Long Term Evolution，LTE)是由3GPP组织制定的UMTS技术标准的长期演进。因为演进关系，我们将LTE接入网部分称为演进的UMTS陆地无线接入网(Evolved UMTS Terrestrial Radio Access Network，E-UTRAN)。对应的，LTE核心网部分可以称为演进的分组核心(Evolved Packet Core，EPC)。区别于3G和4G通信技术标准，将5G接入网部分称为NG-RAN，将5G核心网部分称为5GC。
3)、移动管理实体(Mobility Management Entity，MME)是3GPP协议LTE接入网络的关键控制节点，它负责空闲模式的UE(User Equipment)的定位，传呼过程，包括中继。简单的说MME是负责信令处理部分。服务网关(Serving GateWay，S-GW)是终止于E-UTRAN接口的网关，示例性的，S-GW的主要功能可以包括：进行eNB间切换时，可以作为本地锚定点，并协助完成eNB的重排序功能；在3GPP不同接入网络间切换时，作为移动性锚点，同样具有重排序功能；执行合法侦听功能；进行数据包的路由和前转；在上行和下行传输层进行分组标记；空闲状态下，下行分组缓冲和发起网络触发的服务请求功能；用于运营商间的计费等。
4)、网络设备是无线网络中的设备，例如将终端接入到无线网络的无线接入网(radio access network，RAN)节点。目前，一些RAN节点的举例为：gNB、ng-eNB、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)、路边单元(Roadside Unit，RSU)，或无线保真(wireless fidelity，Wifi)接入点(access point，AP)等。
5)、车辆与其他设备通信：即V2X通信，可以应用于交通运输网络中。V2X通信可以包括车与车(Vehicle to Vehicle，V2V)通信、车与路侧基础设施(Vehicle to Infrastructure，V2I)通信以及车与行人(Vehicle to People，V2P)通信。其中，V2V通信可以在边链路(sidelink)上进行，V2I通信可以在下行链路(Downlink，DL)上进行。
6)、SL通信：基于sidelink的通信。SL通信可以在物理SL控制信道(Pysical Sidelink Control Channel，PSCCH)和/或物理SL共享信道(Pysical Sidelink Share Channel，PSSCH)上传输数据。示例性的，SL通信可以是发生在终端与终端之间的V2X通信。例如，网络设备可以为终端分配用于进行SL通信的资源，如CG资源，又如SPS资源，终端则可以在分配的CG资源和/或SPS资源上与其他终端进行SL通信，如进行数据的传输。
7)、Uu口通信：基于Uu口的终端与网络设备之间的通信。
以下对本申请实施例的具体实施方式进行详细说明。
在终端进行通信之前，需要网络设备为其配置对应的资源。终端在网络设备配置的资源上进行通信。网络设备可以使用动态调度(Dynamic Scheduling，DS)的方法配置上述资源。在本实施例中，可将通过DS的方法配置的资源称为DS资源。网络设备也可以使用SPS的方法配置上述资源。在本实施例中，可将通过SPS的方法配置的资源称为SPS资源。
示例性的，DS资源可以是网络设备在传输时间间隔(Transmission Time Interval，TTI)中，使用小区无线网络临时标识(Cell-Radio Network Temporary Identifier，C-RNTI)加扰的物理下行控制信道(Physical Downlink Control Channel，PDCCH)为终端配置的资源。DS资源具有一次分配，一次使用的特点。也就是说，每进行一次通信，网络设备都需要为终端分配一次DS资源。与之相对的，SPS资源则具有一次分配，多次使用的特点。也就是说，网络设备为终端分配的SPS资源，可以用于终端重复进行多次通信。由于SPS资源相比DS资源具有低PDCCH开销的特点，因此SPS资源更适合周期性的小包业务，如基于IP的语音传输(Voice over Internet Protocol，VOIP)业务等。
目前，终端在进行基于SL的V2X通信时，除了可以使用上述SPS资源外，也可以使用网络设备在新空口(New Radio，NR)中为终端配置的资源，如通过CG的方法配置的资源。在本实施例中，通过CG方法配置的资源可以称为CG资源。示例性的，如图1所示，当终端1需要与终端2进行SL通信时，网络设备可以为该终端1配置用于SL通信的CG/SPS资源。终端1在该资源上便可与终端2进行SL通信。由于CG/SPS资源的配置都是由网络设备完成的，而在一些通信(如图1所示的SL通信)过程中，网络设备并不能知晓为终端所配置的资源的使用情况，也就无法对为终端配置的资源进行合理的处理(如对空闲的CG/SPS资源进行删除或者去激活)，这也就不可避免地会造成资源的浪费。
在面对上述问题时，在现有技术中，终端可以通过终端辅助消息(UE assistance information，UAI)向网络设备上报业务模式(traffic pattern)信息，以便网络设备可以根据该业务模式信息，对该终端的资源进行管理。示例性的，网络设备可以根据业务模式信息中的业务周期(traffic periodicity)确定是否对某个周期的CG/SPS资源进 行管理。例如，终端向网络设备反馈的业务周期包括(sf20，sf50，sf100，sf200)，那么网络设备就可以为该终端配置周期为20,50,100,200的CG/SPS资源。此后如果终端向网络设备反馈的业务周期包括(sf50，sf100，sf200)，那么网络设备就可以将为该终端配置的资源修改为周期为50,100,200的CG/SPS资源，即网络设备可以将配置给该终端的周期为20的CG/SPS资源进行删除或去激活的处理。
然而，通过UAI实现去激活或删除资源的方法依然存在一些问题：
1)、在SL通信场景下，终端与网络设备之间可能不存在Uu口的上行资源。如果终端需要向网络设备通过UAI上报业务模式信息，那么终端就需要在发送业务模式信息之前向网络设备申请Uu口的上行资源，这无疑会产生额外的信令开销。
2)、UAI是一种RRC信令，在网络架构上处于物理层和介质访问控制(Media Access Control，MAC)层之上，相比于MAC信令以及物理层信令，需要耗费较长时间才能够被接收网络设备接收。
3)、当网络设备为终端配置了两个或两个以上相同周期的CG/SPS资源时，通过UAI信令，网络设备就无法识别需要删除或去激活的CG/SPS资源。例如，网络设备为终端配置了周期分别为20,50,20,100的CG资源，此后如果接收到终端发送的包括(sf20,sf50,sf100)的业务模式信息时，网络设备就无法区分需要删除或去激活哪个周期为20的CG资源，也就无法进行正确的资源管理。
目前，网络设备除了可以根据终端发送的UAI对为终端配置的CG/SPS资源进行相应处理之外，还可以使用MAC CE作为处理CG/SPS资源的参考。但是，MAC CE虽然属于MAC信令，其收发速度快于RRC信令(如UAI)，但是依然会比物理层信令慢,同时也存在上述其他问题。
本申请实施例提供一种通信方法，能够使网络设备高效地对配置给终端的CG/SPS资源进行相应处理，如删除或去激活配置给终端的CG/SPS资源，以避免资源的浪费。
以下结合附图对本申请提供的通信方法进行详细说明。
请参考图2，为本申请实施例提供的一种网络架构示意图。以LTE网络为例，作为一种示例，该网络架构可以包括E-UTRAN和EPC。该E-UTRAN可以由一个或多个eNB组成，而EPC可以包括一个或多个S-GW和MME。其中，eNB之间可以通过X2接口相互连接。E-UTRAN中的eNB可以通过S1接口连接到MME或者S-GW。例如，E-UTRAN中的eNB可以通过S1-MME接口连接到MME，又如，E-UTRAN中的eNB可以通过S1-U接口连接到S-GW。
请参考图3，为本申请实施例提供的另一种网络架构示意图。以5G网络为例，作为一种示例，该网络架构可以包括由一个或多个gNB和/或一个或多个ng-eNB组成的NG-RAN，以及由一个或多个接入和移动管理功能实体(Core Access and Mobility Management Function，AMF)和/或一个或多个用户计划功能实体(User plane Function，UPF)组成的5GC。gNB与ng-NB之间可以通过Xn接口互相连接，gNB与ng-NB都可以通过NG接口连接到5GC。
其中，在上述图2或图3所示的网络架构下，对于V2X通信而言，eNB或者gNB下层的设备(即能够与如图2中所示的eNB以及能够与如图3中所示的gNB和/或ng-eNB进行通信的终端)均可被称为V2X通信中的终端。示例性的，在如图4所示 的V2X通信场景下，设备1，设备2，以及设备3，都可以称为该场景下的终端。本实施例中所述的终端可以为上述V2X通信中的终端。
本申请实施例提供的通信方法可应用于V2X通信中。用于支持V2X通信的网络可以为任意移动通信网络，如，图2或图3所示的网络。另外，本实施例的技术方案可应用于V2X通信的任意场景中，如，图1或图4所示的场景。例如，当如图1所示的场景发生在如图2所示的网络架构下时，即图1中的网络设备为图2中的eNB，则eNB可以为终端1配置进行V2X通信的资源(如CG/SPS资源)，而终端1可以根据eNB为其配置的CG/SPS资源与终端2进行SL通信。又如，当如图4所示的场景发生在如图3所示的网络架构下时，即图4中的网络设备为图3中的gNB或ng-eNB，则gNB和/或ng-eNB可以为设备1以及设备2配置进行V2X通信的资源(如CG/SPS资源)，那么设备1就可以在配置的CG/SPS资源上实现与设备3的SL通信，类似的，设备2也可以在配置的CG/SPS资源上实现与设备1的SL通信。可以理解的是，如图1所示的场景也可以发生在如图3所示的网络架构下，并实现其中终端之间的SL通信，而如图4所示的场景也可以发生在如图2所示的网络架构下，并实现其中设备之间的SL通信。当然，本申请实施例所涉及的V2X通信(如SL通信)场景，并不限于如图1所示的场景或如图4所示的场景，还可以是其他的能够进行V2X通信的场景。此处仅以图1所示的场景以及图4所示的场景为例进行说明，并不构成任何限制。
本申请实施例提供的通信方法，终端可以在网络设备为终端配置的物理层资源上指示网络设备对传输资源，如CG资源或SPS资源进行处理。在接收到该指示后，网络设备可以对与该物理层资源对应的传输资源进行处理。其中，网络设备对传输资源的处理可以是去激活或删除。这样就可以实现网络设备对传输资源的高效管理，有效地避免资源浪费。其中，为了更加清楚的对本申请实施例进行说明，以下示例中以传输资源为CG资源为例进行说明。
请参考图5，为本申请实施例提供的一种通信方法的流程示意图。该方法可以包括S501-S504。
S501、网络设备向终端发送第一配置信息，第一配置信息包括第一资源信息和第二资源信息，第一资源信息用于指示第一传输资源，第二资源信息用于配置物理上行控制信道，第一传输资源与物理上行控制信道对应。
其中，第一传输资源是网络设备为终端分配的用于进行SL通信的传输资源。
示例性的，为了支持终端的V2X通信(如SL通信)，网络设备可以为终端配置1个或多个CG资源，并将用于指示这些CG资源的第一资源信息通过配置信息发送给终端。本申请实施例中，第一传输资源可以是这些CG资源中的任意一个。
例如，网络设备需为终端配置包括CG 1、CG 2以及CG 3的CG资源。网络设备可以向终端发送包括资源信息1的配置信息1，该资源信息1用于指示CG 1。网络设备还可以向终端发送包括资源信息2的配置信息2，该资源信息2用于指示CG 2。网络设备还可以向终端发送包括资源信息3的配置信息3，该资源信息3用于指示CG 3。
网络设备还可以为终端配置与上述CG资源对应的物理上行控制信道(Physical Uplink Control Channel，PUCCH)，即网络设备可以为每个CG资源分别配置对应的PUCCH，并将用于指示这些PUCCH的第二资源信息发送给终端。
例如，继续结合上述示例，网络设备可以为终端配置与CG 1对应的PUCCH 1，与CG 2对应的PUCCH 2，以及与CG 3对应的PUCCH 3。网络设备可以向终端发送资源信息A，该资源信息A用于配置PUCCH 1。网络设备还可以向终端发送资源信息B，该资源信息B用于配置PUCCH 2。网络设备还可以向终端发送资源信息C，该资源信息C用于配置PUCCH 3。
其中，网络设备可以将用于配置PUCCH的第二资源信息与对应的用于指示CG资源的第一资源信息一同下发给终端。例如，继续结合上述示例，网络设备可以将上述资源信息1与资源信息A一同携带在上述配置信息1中下发给终端。将上述资源信息2与资源信息B一同携带在上述配置信息2中下发给终端。将上述资源信息3与资源信息C一同携带在上述配置信息3中下发给终端。
需要说明的是，网络设备可以将上述配置信息1、配置信息2以及配置信息3分别发送给终端，也可以将上述配置信息一起发送给终端。另外，网络设备对于不同CG资源以及与CG资源对应的PUCCH的配置，可以是同时的，也可以是在不同时间配置的。
S502、终端接收来自网络设备的第一配置信息。
终端根据接收到的第一配置信息，就能够知晓与网络设备为终端分配的CG资源以及与该CG资源对应的PUCCH。
示例性的，继续结合上述S501中的示例，终端可以根据配置信息1中包括的资源信息1知晓网络设备为SL通信分配了CG 1。终端还可以根据配置信息1中包括的资源信息A知晓与CG 1对应的PUCCH 1。类似的，终端可以根据配置信息2知晓网络设备为SL通信分配了CG 2，及与该CG 2对应的PUCCH 2，终端可以根据配置信息3知晓网络设备为SL通信分配了CG 3，及与该CG 3对应的PUCCH 3。
S503、终端通过物理上行控制信道向网络设备发送第一指示信息，第一指示信息用于指示处理第一传输资源。
其中，该第一指示信息可以是确认指示。其中，该确认指示可以是ACK指示，也可以是其他具有确认功能的指示信息。示例性的，该ACK指示可以由1个比特来表示，如该ACK指示可以为“1”。
本申请实施例中，终端始终都是通信(如SL通信)的参与者，因此，终端能够知晓网络设备为当前通信配置的资源的使用情况。终端根据使用情况在确定需要网络设备对为其配置的资源进行处理时，可向网络设备发送第一指示信息，用于指示网络设备对配置的资源(如第一传输资源)进行处理。
其中，如上述实施例中的描述，网络设备为终端配置的资源可以分为第一类资源和第二类资源。第一类资源是配置后立即生效的资源，第二类资源是配置后需激活才会生效的资源。针对不同种类的资源的处理方法不同。例如，上述对资源的处理可以是删除，或者是去激活。
例如，网络设备为终端配置了CG 1、CG 2以及CG 3。以第一传输资源是CG 1，CG 1是第二类资源为例。如果终端确定不需要使用该CG 1，而该CG 1已经被激活，则终端可以通过与CG 1对应的PUCCH 1，向网络设备发送包括ACK指示的第一指示信息。该第一指示信息用于指示去激活CG 1。
又例如，网络设备为终端配置了CG 1、CG 2以及CG 3。以第一传输资源是CG 2，CG 1是第一类资源为例。如果终端确定不需要使用CG 2，则终端可以通过与CG 2对应的PUCCH 2，向网络设备发送包括ACK指示的第一指示信息，用于指示删除CG 2。
可以理解的是，对于终端发送给网络设备的信息，通常网络设备需要进行解析方可执行与之对应的操作。而在该解析过程中，可能存在一些错误解析的情况。例如，以终端发送给网络设备的信息是上述第一指示信息为例。终端发送给网络设备的第一指示信息为ACK指示，例如该ACK指示的内容为1个比特的“1”。网络设备在对该信息进行解析时，可能会存在将其错误解析为“0”的情况。虽然这种错误解析的情况发生概率较低，但是也会一定程度地影响网络设备对终端发送指示的误判。因此，在一些实施例中，终端在确定需要对网络设备为其配置的CG资源进行处理时，可以在该CG资源对应的PUCCH上向网络设备发送N个用于处理该CG资源的第一指示信息，以便网络设备可以明确地知晓需要对该CG资源进行处理。其中，N为大于1的整数。在另一些实施例中，终端可以在预设时间内，在该CG资源对应的PUCCH上向网络设备发送N个第一指示信息。示例性的，可以在终端中预置定时器，当终端确定需要网络设备对为其配置的CG资源进行处理时，触发定时器开始计时，终端可以在该定时器计时结束之前，在该CG资源对应的PUCCH上向网络设备发送N个第一指示信息。
需要说明的是，在V2X通信的一些场景下存在使用ACK指示的情况。示例性的，在终端接收到网络设备为其配置的CG资源之后，可以在该CG资源上与其他终端进行SL通信，如终端(如终端1)可以在该CG资源上向其他终端(如终端2)发送数据。如果终端2确定成功地接收到数据时，可以向终端1发送ACK指示，用于指示终端1已经成功接收到该数据。之后，终端1可以向基站发送ACK指示，用于告知网络设备在当前CG资源上进行的SL通信已经成功。可以理解的是，由于当前SL通信已经成功，网络设备在接收到终端1发送的ACK之后，并不需要对该ACK指示做任何响应。因此，这种方法中终端1向网络设备发送的ACK指示就显得没有必要，而且会增加网络设备与终端之间的信令开销。
本申请实施例中，网络设备可以向终端发送用于指示终端在上述场景下(即在SL通信中传输的数据不需要重传时)不向网络设备发送ACK指示。终端可以接收来自网络设备的该第二配置信息。示例性的，当确定SL通信成功，即不需要进行数据重传时，终端可以根据该第二配置信息，不向网络设备发送ACK指示。这样，终端就可以利用该ACK指示向网络设备传递其他信息，如通过该ACK指示向网络设备指示对第一传输资源进行删除或去激活的处理。
S504、网络设备通过物理上行控制信道接收来自终端的第一指示信息，处理第一传输资源。
网络设备在通过PUCCH接收到来自终端的第一指示信息后，可以对与该PUCCH对应的第一传输资源进行相应处理。
如，结合S503中的示例，以第一指示信息可以是1比特的ACK指示，第一传输资源是CG 1，CG 1是第二类资源为例。网络设备通过PUCCH 1接收到来自终端的ACK指示时，网络设备可以根据接收ACK指示的物理层资源，即PUCCH 1确定去激 活该PUCCU 1对应的CG资源，即CG 1。又如，结合S503中的示例，以第一指示信息是1比特的ACK指示，第一传输资源是CG 2，CG 2是第一类资源为例。网络设备通过PUCCH 2接收到来自终端的ACK指示时，网络设备可以根据接收ACK指示的物理层资源，即PUCCH 2确定删除该PUCCU 2对应的CG资源，即CG 2。
在终端向网络设备发送了N个第一指示信息的场景下。在一些实施例中，上述网络设备处理第一传输资源，具体的可以为：网络设备在接收到来自终端的多个第一指示信息后，对第一传输资源进行处理。示例性的，可以在网络设备中定义一个计数器(counter)N，其中N为大于1的整数。当网络设备接收到来自终端的第一个ACK指示时，counter置为1，接着网络设备每接收到一个ACK指示，counter的数值加1，直至counter的数值等于N时，网络设备确定要对接收该ACK指示的PUCCH对应的CG资源进行处理，那么网络设备就可以处理该CG资源。
在另一些实施例中，上述网络设备处理第一传输资源，具体的可以为：网络设备可以确定在预设时间内，counter的数值达到N时，对第一传输资源进行处理。示例性的，可以在网络设备中设置定时器(timer)。当网络设备接收到来自终端的第一个ACK指示时，timer开始计时，并将counter置为1，接着网络设备每接收到一个ACK指示，counter的数值加1，当网络设备确定在timer超时之前，counter的数值达到N，则确定需要对接收该ACK指示的PUCCH对应的CG资源进行处理，那么网络设备就可以处理该CG资源。
可以理解的是，网络设备为终端配置的资源，如CG资源都具有一定的周期。在该周期内，CG资源能够支持终端进行通信(如SL通信)。本申请实施例中，网络设备可以通过对与CG资源对应的PUCCH的监控实现对上述指示信息(如第一指示信息)的准确接收。而如果网络设备在分配了CG资源之后的任意时刻都对所有已经分配的CG资源对应的PUCCH进行监控，就会对网络设备产生较大的负担。
因此，在本申请的一些实施例中，网络设备中可以设置timer，用于对网络设备监视各个PUCCH的时间进行规划，以提高网络设备的工作效率。示例性的，以网络设备为终端分配了CG 1、CG 2以及CG3，并且分别为这些CG资源对应分配了PUCCH 1、PUCCH 2以及PUCCH3为例进行说明。网络设备可以在CG 1生效的周期内的任意时刻，启动timer，开始对PUCCH 1进行监控。如果在该timer超时之前，网络设备在PUCCH 1上接收到了ACK指示，则网络设备就可以对CG 1进行删除或去激活的处理。类似的，网络设备可以在CG 2生效的周期内的任意时刻，启动timer，开始对PUCCH 2进行监控。如果在该timer超时之前，网络设备在PUCCH 2上接收到了ACK指示，则网络设备就可以对CG 2进行删除或去激活的处理。网络设备可以在CG 3生效的周期内的任意时刻，启动timer，开始对PUCCH 3进行监控。如果在该timer超时之前，网络设备在PUCCH 3上接收到了ACK指示，则网络设备就可以对CG 3进行删除或去激活的处理。在timer超时后，网络设备停止对对应PUCCH的监控，以达到降低网络设备负担的目的。
另外，本申请实施例提供的通信方法，还可以用于为终端配置(如激活或添加)资源，如CG资源的过程中。示例性的，终端可以在PUCCH上向网络设备发送指示信息，用于指示网络设备激活或添加CG资源。网络设备可以根据该指示信息，进行 CG资源的激活或添加。
例如，网络设备为终端(如UE 1)分配了CG 1、CG 2以及CG 3，并且分别为这些CG资源对应分配了PUCCH 1、PUCCH 2以及PUCCH3。UE 1可以在这些CG资源上与其他终端(如UE 2)进行数据传输。当UE 2并未在CG 3上成功接收UE 1发送的数据时，可以向UE 1返回混合自动重传请求(Hybrid Automatic Repeat Request，HARQ)，用于指示UE1对在CG 3上传输的数据进行重传。UE1可以在与CG 3源对应的PUCCH 3上，向网络设备发送否定(NACK)指示，用于指示网络设备分配重传资源。网络设备在接收到该NACK指示时，可以为终端配置重传资源。其中，网络设备为终端配置重传资源可以是为该终端添加新的第一类CG资源，也或者，可以是为该终端已经配置的但未激活的第二类CG资源。另外，该重传资源还可以是网络设备通过动态配置(Dynamic Grant)的方法为终端配置的。本申请实施例在此不做限制。
需要说明的是，上述实施例均以网络设备为终端配置的资源为CG资源为例进行说的，本申请实施例提供的通信方法，也可以应用于网络设备为终端配置的资源为Uu口上行SPS资源，或者Uu口下行SPS资源，或者SL上的SPS资源的场景下。其具体的实施方式与图5示出的步骤相同，此处不再赘述。
本申请实施例提供的通信方法，终端在网络设备配置的与CG/SPS资源对应的PUCCH上指示网络设备对CG/SPS资源进行处理。由于本申请所述方法是通过PUCCH进行指示信息的传输，因此传输速度会明显高于RRC信令或者MAC信令的传输。另外，由于PUCCH与为终端配置的CG/SPS资源是对应的，如果终端需要指示网络设备对具有相同周期的两个或多个资源中的部分资源进行处理时，通过在于需要处理的资源对应的PUCCH上发送指示信息，以便网络设备可以根据接收指示信息的PUCCH准确的判断需要处理的资源。同时，本申请所述方法中通过1比特的ACK指示作为去激活/删除的指示信息，该信息的数据量非常小，因此不会对终端与网络设备之间的通信造成额外的负担。并且当终端与网络设备之间的通信质量无法得到保证时，网络设备也可以比较容易的获取该指示信息。因此，通过本申请实施例提供的通信方法，能够达到网络设备高效地对CG/SPS资源进行处理，避免资源浪费的目的。
