一种基于配置授权的通信方法及装置
相关申请的交叉引用
本申请要求在2023年04月07日提交中国国家知识产权局、申请号为202310406137.6、申请名称为“一种基于配置授权的通信方法及装置”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本申请涉及通信技术领域，尤其涉及一种基于配置授权的通信方法及装置。
背景技术
随着无线通信系统的不断发展，数据传输时延不断降低，传输容量越来越大。无线通信系统逐渐渗入一些实时性强、数据容量要求大的业务，比如视频传输、云游戏(cloud gaming，CG)、扩展现实(extended reality，XR)等。其中，XR是指通过计算机技术和可穿戴设备产生的一个真实与虚拟组合、可人机交互的环境，是增强现实(augmented reality，AR)、虚拟现实(virtual reality，VR)、混合现实(mixed reality，MR)等多种形式的统称。
以XR业务为例，接入网设备和终端之间可以通过半静态调度的方式传输XR业务的数据帧，比如接入网设备可以配置多个传输时机来传输一个数据帧，这多个传输时机所能承载的数据量可能大于数据帧的数据量，从而会导致多个传输时机中的部分传输时机未被使用，造成传输资源的浪费。
发明内容
本申请提供了一种通信方法及装置，用于实现终端通知接入网设备不使用的传输时机，以便于接入网设备将不使用的资源分配给其它终端，提高资源利用率。
第一方面，本申请实施例提供一种通信方法，该方法可以应用于终端或者终端中的模块(例如电路或者芯片)，还可以应用于能实现全部或部分终端功能的逻辑节点、逻辑模块或软件。其中，该方法可以包括：接收配置信息，所述配置信息用于配置承载指示信息的第一CG传输时机和所述指示信息作用的第一时段，所述指示信息用于指示所述第一时段内使用或不使用的CG传输时机；在所述第一CG传输时机上发送所述指示信息。
采用上述方法，终端可以根据第一配置信息，在第一传输时机上向接入网设备发送指示信息，以通知接入网设备不使用的传输时机，以便于接入网设备将不使用的资源分配给其它终端，提高资源利用率。此外，由于接入网设备是通过第一配置信息来统一配置第一传输时机和指示信息的作用的第一时段，因此，终端发送指示信息时，无需额外指示指示信息作用的第一时段，从而便于节省信令开销。
在一种可能的设计中，所述配置信息还用于配置CG周期时段内的CG传输时机，所述CG周期时段内的CG传输时机包括所述第一CG传输时机，所述CG周期时段包括所述第一时段。如此，配置信息可以通过配置CG周期时段内的CG传输时机来隐式配置第一传输时机和第一时段，从而便于节省信令开销，实现较为简单。
在一种可能的设计中，所述第一CG传输时机和所述第一时段内使用或不使用的CG传输时机对应相同的CG或不同的CG。
也就是说，第一CG传输时机和第一时段内使用或不使用的CG传输时机可以属于同一套CG，或者也可以属于不同套CG，从而使得上述方案可以适用于多种配置CG传输时机的场景。此外，当第一CG传输时机和第一时段内使用或不使用的CG传输时机属于不同套CG时，第一CG传输时机上承载的指示信息可以作用在不同套CG传输时机，从而可以使得配置更加灵活。
在一种可能的设计中，所述第一CG传输时机为所述第一时段内的首个CG传输时机。如此，在首个传输时机上发送指示信息，便于接入网设备尽早获知不使用的传输时机。
在一种可能的设计中，所述指示信息用于指示第二时段，所述第一时段包括所述第二时段；所述第一时段内使用或不使用的CG传输时机位于所述第二时段内。
如此，由于第一时段内使用或不使用的CG传输时机位于第二时段，也就是说，指示信息可以指示位于第二时段内的传输时机是否使用，而无需指示第一时段内的所有传输时机是否使用，从而便于节省传输资源。
在一种可能的设计中，所述指示信息包括比特位图。如此，使用比特位图可以指示连续的CG传输时机不使用，或者也可以指示非连续的CG传输时机不使用，从而使得指示更加灵活。
在一种可能的设计中，所述比特位图中的一个比特用于指示多个所述使用或不使用的CG传输时机。如此，由于一个比特可以指示多个使用或不使用的CG传输时机，从而便于减少比特位图的位宽，节省传输资源。
在一种可能的设计中，所述比特位图的位宽由所述配置信息配置。也就是说，接入网设备可以通过配置比特位图的位宽来隐式配置第一时段。如此，有利于网络侧和终端侧明确比特位图的位宽，便于指示信息的解码。
第二方面，本申请实施例提供一种通信方法，该方法可以应用于接入网设备或者接入网设备中的模块(例如电路或者芯片)，还可以应用于能实现全部或部分接入网设备功能的逻辑节点、逻辑模块或软件。其中，该方法可以包括：发送配置信息，所述配置信息用于配置承载指示信息的第一CG传输时机和所述指示信息作用的第一时段，所述指示信息用于指示所述第一时段内使用或不使用的CG传输时机；在所述第一CG传输时机上接收所述指示信息。
在一种可能的设计中，所述配置信息还用于配置CG周期时段内的CG传输时机，所述CG周期时段内的CG传输时机包括所述第一CG传输时机，所述CG周期时段包括所述第一时段。
在一种可能的设计中，所述第一CG传输时机和所述第一时段内使用或不使用的CG传输时机对应相同的CG或不同的CG。
在一种可能的设计中，所述第一CG传输时机为所述第一时段内的首个CG传输时机。
在一种可能的设计中，所述指示信息用于指示第二时段，所述第一时段包括所述第二时段；所述第一时段内使用或不使用的CG传输时机位于所述第二时段内。
在一种可能的设计中，所述指示信息包括比特位图。
在一种可能的设计中，所述比特位图中的一个比特用于指示多个所述使用或不使用的CG传输时机。
在一种可能的设计中，所述比特位图的位宽由所述配置信息配置。

具体实施方式
下面将结合本申请实施例中的附图，对本申请实施例中的技术方案进行描述。本申请实施例中的技术方案可以应用于各种通信系统，例如通用移动通信系统(universal mobile telecommunications system，UMTS)、无线局域网(wireless local area network，WLAN)、无线保真(wireless fidelity，Wi-Fi)系统、第4代(4th generation，4G)移动通信系统，如长期演进(long term evolution，LTE)系统、第五代(5th generation，5G)移动通信系统，如新空口(new radio，NR)系统，以及未来演进的通信系统，如第六代(6th generation，6G)移动通信系统等。
本申请将围绕可包括多个设备、组件、模块等的系统来呈现各个方面、实施例或特征。应当 理解和明白的是，各个系统可包括另外的设备、组件、模块等，并且/或者可以并不包括结合附图讨论的所有设备、组件、模块等。此外，还可以使用这些方案的组合。
为便于理解本申请实施例，图1示出了一种可能的、非限制性的系统示意图。如图1所示，通信系统10包括无线接入网(radio access network，RAN)100和核心网(core network，CN)200。可选地，通信系统10还可以包括互联网300。
RAN 100包括至少一个RAN节点(如图1中的110a和110b，统称为110)和至少一个终端(如图1中的120a-120j，统称为120)。其中，110a是基站，110b是微基站，120a、120e、120f和120j是手机，120b是汽车，120c是加油机，120d是布置在室内或室外的家庭接入节点(home access point，HAP)，120g是笔记本电脑，120h是打印机，120i是无人机。
RAN100中还可以包括其它RAN节点，例如无线中继设备和/或无线回传设备(图1中未示出)等。终端120通过无线的方式与RAN节点110相连。RAN节点110通过无线或有线方式与核心网200连接。核心网200中的核心网设备与RAN 100中的RAN节点110可以分别是不同的物理设备，也可以是集成了核心网逻辑功能和无线接入网逻辑功能的同一个物理设备。

下面先对本申请实施例所涉及的相关术语进行解释说明。需要说明的是，这些解释是为了让本申请实施例更容易被理解，而不应该视为对本申请所要求的保护范围的限定。
一、数据帧
数据帧也可以称为数据片(slice)或数据块(tile)。针对于某一业务(比如XR业务)，该业务可以包括至少一个数据帧，或者至少一个协议数据单元(protocol data unit，PDU)集合(PDU set)，一个PDU set中可以包含至少一个数据帧。
本申请实施例中，数据帧可以为视频帧、音频帧或者其它可能的帧。
(1)数据帧的传输周期
以数据帧为视频帧为例，视频可以是由一张张连贯起来的图像(或者说图片、照片等)连续播放组成的，当一秒钟有24张图像快速播放，人眼就会认为这是连续的画面(即视频)。帧率是指每秒钟播放的图像数量，比如当帧率为24帧每秒钟(frame per second，FPS)时，表示每秒钟播放24张图像，当帧率为60FPS时，表示每秒钟播放60张图像，以此类推。
以XR业务为例，其业务模型通常是视频帧根据帧率周期性到达。当帧率为60FPS时，理想情况下，视频帧的传输周期为1000/60＝50/3毫秒(ms)，约等于16.67ms，即每隔16.67ms到达一个视频帧。
图2A为多个视频帧的传输示意图。如图2A所示，视频帧1、视频帧2和视频帧3为连续的3个视频帧，比如帧率为60FPS，视频帧的传输周期为1000/60＝50/3毫秒(ms)，约等于16.67ms。以视频帧1为例，视频帧1中包括多个数据包；示例性地，多个数据包可以分布在视频帧1的传输周期的前段(比如多个数据包可以分布在16.67ms的前8ms内)。也就是说，不同视频帧之间可以存在一段传输时间间隔(gap)。
(2)数据帧的数据量
仍以数据帧为视频帧为例，一个视频帧可以理解为一张图像，一个视频帧可以包括一张图像对应的一个或多个数据包，一个视频帧的数据量即为该视频帧所包括的一个或多个数据包的数据量之和。
进一步地，同一业务的不同视频帧的数据量可能不同。导致不同视频帧的数据量不同的原因有多种。比如，针对于两个连续的视频帧(如图2A中的视频帧1和视频帧2)，视频帧1和视频帧2的压缩率可能不同，编码类型也可能不同(比如视频帧1的编码类型为帧内编码，视频帧2的编码类型为帧间预测编码)，从而会导致视频帧1和视频帧2的数据量不同。
二、半静态调度
接入网设备为终端调度上下行传输资源的方式可以有两种，即动态调度和半静态调度。在动态调度中，接入网设备可以通过控制信道向终端发送控制信息，从而为终端分配数据信道的传输参数。其中，控制信道比如为物理下行控制信道(physical downlink control channel，PDCCH)，控制信息比如可以为下行控制信息(downlink control information，DCI)；数据信道比如可以为物理下行共享信道(physical downlink shared channel，PDSCH)或物理上行共享信道(physical uplink shared channel，PUSCH)。示例性地，控制信息可以指示数据信道所映射的时频位置(比如，数据信道所映射的时域符号、频域资源块(resource block，RB))，进而接入网设备和终端在该时频位置上，可以通过数据信道传输下行数据(比如PDSCH携带的数据)和/或上行数据(比如PUSCH携带的数据)。
在半静态调度中，接入网设备可以为终端分配周期性的上下行传输资源。以上行传输资源为例，用于分配上行传输资源的半静态调度可以称为配置授权(configured grant，CG)。进一步地，用于进行一次上行传输的传输资源可以称为一个CG传输时机(可简称为传输时机)，CG传输时机也可以替换为其它可能的描述，比如CG资源或PUSCH资源或PUSCH机会或PUSCH时机。
下面对传输时机的配置方式进行描述。
(1)作为一种可能的实现，接入网设备可以先通过无线资源控制(radio resource control，RRC)消息为终端配置至少一套传输时机的部分参数(比如CG周期、CG索引等)。比如，RRC消息可以包括至少一套传输时机中每套传输时机对应的ConfiguredGrantConfig(或CG-Config)字段，每套传输时机的CG周期、CG索引等参数可以承载在每套传输时机对应的CG-Config字段中。其中，一套传输时机可以包括周期性出现的多个传输时机，CG索引用于区分不同套传输时机，同一套传输时机对应同一个CG索引；CG索引可以通过ConfiguredGrantConfig字段中的ConfiguredGrantConfigIndex参数来配置，CG索引也可以有其它可能的名称，本申请实施例对此不做限定。
进一步地，针对至少一套传输时机中的每套传输时机，接入网设备可以向终端发送激活命令，激活命令用于激活该套传输时机；其中，激活命令比如可以为PDCCH中的DCI。示例性地，激活命令可以包括该套传输时机的另一部分参数，比如另一部分参数包括参数1和参数2。参数1指示该套传输时机中每个传输时机的频域位置，属于同一套传输时机的不同传输时机的频域位置相同；参数2指示该套传输时机中每个传输时机的时域位置，属于同一套传输时机的不同传输时机的时域长度相同，传输时机的时域长度可以是指传输时机在时域上持续的符号个数。
其中，参数1指示传输时机的频域位置的方式可以多种。比如，方式1：参数1包括一个位图，该位图指示传输时机所包括的资源块组(resource block group，RBG)；方式2：参数1包括资源指示值(resource indication value，RIV)，RIV指示传输时机的起始RB(可表示为RBstart)和频域上连续RB的数量(可表示为LRB)。
参数2指示传输时机的时域位置的方式可以多种。比如，参数2包括时域资源分配(time domain resource assignment，TDRA)字段，TDRA字段中包括K2、起始和长度指示值(start and length indicator value，SLIV)。其中，K2指示激活命令和传输时机(比如该套传输时机中的第一个传输时机)之间的时隙(slot)偏移值，SLIV指示该传输时机的起始符号位置和该套传输时机中每个传输时机的时域长度。
(2)作为又一种可能的实现，接入网设备通过RRC消息配置至少一套传输时机中每套传输时机的CG周期以及指示具体的时频位置，比如通过参数1和参数2来指示具体的时频位置，此种情形下，CG周期以及参数1和参数2均承载于RRC消息；终端一旦正确接收到RRC消息，配置就立即生效(也就是说，配置即激活)。
三、半静态调度增强技术
对于不同的XR业务，其上行和下行的业务模型通常也不相同。比如，针对于VR业务，场景内容显示的变化是由用户的姿态或位置(动作)引发的，因此，上行传输的主要是位置和姿态信息，数据量小，通常只有几十kbps；下行传输的主要是渲染后的视频流，数据量比较大，可达几十到上百Mbps。针对于AR业务，场景内容显示的变化是由注视聚焦目标的变化以及位置和注视点之间空间关系变化(动作)引发的，因此，上行传输的内容包含了感知所需要的视觉信息(包含深度)，上行传输的主要是清晰和稳定的图片或者视频流，数据量较大，也可以是一些抽取出的环境特征信息。
以上行传输为例，接入网设备通过CG为终端配置并激活一套传输时机后，终端可以在该套传输时机上向接入网设备发送数据帧。通常情况下，每个CG周期时段内只能配置一个传输时机，也就是每个CG周期时段内只能传输一个传输块(transport block，TB)。比如，接入网设备配置的CG周期与数据帧的传输周期匹配(具体匹配的方式可以有多种，比如二者相同，本申请实施例对此不做限定)，以使得一个数据帧对应一个传输时机，即一个数据帧在一个传输时机上传输。比如参见图2B所示，假设CG周期与数据帧的传输周期相同，终端可以在传输时机k上传输数据帧k，在传输时机k+1上传输数据帧k+1，在传输时机k+2上传输数据帧k+2，以此类推。
本申请中，CG周期可以表示CG周期时长，比如CG周期为50ms；CG周期时段可以表示具有CG周期时长的一段时间，比如CG周期时段为从时间点a到时间点b，时间点a到时间点b之间的时长为CG周期。
然而，对于上行数据量较大的业务(比如AR业务)，一个CG周期时段内配置一个传输时机，可 能无法完成数据的传输。为解决这一问题，本申请实施例提供几种半静态调度增强技术，以满足数据量较大的传输需求。下面结合配置方式1至配置方式3对本申请实施例提供的半静态调度增强技术进行介绍。
(1)配置方式1A
在配置方式1A中，接入网设备可以为终端配置一套具有CG周期较短的传输时机，从而形成密集的传输时机，使得每个数据帧的传输周期内包括多个传输时机，进而终端可以有足够的资源来传输数据帧。
举个例子，参见图2C所示，假设CG周期等于数据帧的传输周期的一半，则每个数据帧的传输周期内包括两个传输时机。比如，终端可以在传输时机k和传输时机k+1上传输数据帧k，在传输时机k+2和传输时机k+3上传输数据帧k+1，在传输时机k+4和传输时机k+5上传输数据帧k+2，以此类推。
(2)配置方式2A
在配置方式2A中，接入网设备可以为终端配置一套传输时机，该套传输时机的每个CG周期时段内包括多个传输时机，从而使得每个数据帧的传输周期内包括多个传输时机。
举个例子，参见图2D所示，CG的周期等于数据帧的传输周期，一个CG周期时段内包括两个传输时机，终端可以在每个传输时机所包括的两个传输时机上传输数据帧。比如终端在传输时机k和传输时机k+1上传输数据帧k，在传输时机k+2和传输时机k+3上传输数据帧k+1，在传输时机k+4和传输时机k+5上传输数据帧k+2，以此类推。
(3)配置方式3A
在配置方式3A中，接入网设备可以为终端配置多套CG周期相同但时域起始位置不同的传输时机，从而使得每个数据帧的传输周期内包括多个传输时机。
举个例子，参见图2E所示，接入网设备可以为终端配置两套CG周期相同但时域起始位置不同的传输时机，其中，第一套传输时机和第二套传输时机的CG周期均等于数据帧的传输周期。比如终端在传输时机k和传输时机k+1上传输数据帧k，在传输时机k+2和传输时机k+3上传输数据帧k+1，在传输时机k+4和传输时机k+5上传输数据帧k+2，以此类推。
可以理解的是，此处主要描述了配置方式1、配置方式2和配置方式3与前文所述的半静态调度的差异之处，除此差异之处的其它内容，可以参照前文所述的半静态调度。
四、周期不规则的传输时机
由于CG周期的最小单位为时隙，而数据帧的传输周期可能不是时隙的整数倍(比如数据帧为视频帧，当帧率为60FPS时，数据帧的传输周期为50/3ms，不是时隙的整数倍)，因此，若配置一套传输时机来传输XR业务的数据帧，则会出现CG周期与数据帧的传输周期不匹配的问题。
比如，参见图3A所示，接入网设备为终端配置的一套传输时机的周期为16.5ms，该套传输时机可以包括传输时机k、传输时机k+1、传输时机k+2、传输时机k+3等。当数据帧k到达时，由于数据帧k的到达时间在传输时机k的起始时间之前，因此终端可以在传输时机k上发送数据帧k；当数据帧k+1到达时，由于数据帧k+1的到达时间在传输时机k+1的起始时间之前，因此终端可以在传输时机k+1上发送数据帧k+1；当数据帧k+2到达时，由于数据帧k+2的到达时间在传输时机k+2的起始时间之后，因此终端无法在传输时机k+2上发送数据帧k+2，从而会导致传输时机k+2上没有进行数据传输。
针对于上述问题，可以配置一套周期不规则的传输时机，从而使得传输时机与数据帧的到达时间匹配，下面描述三种可能的配置方式，分别为配置方式1B、配置方式2B和配置方式3B。
(1)配置方式1B
接入网设备可以为终端配置CG周期和偏移量列表(offset list)。举个例子，数据帧的帧率为60FPS(即数据帧的传输周期约为16.67ms)，则CG周期可以配置为50ms，offset list可以配置为[0 17 34]，即offset(0)＝0ms，offset(1)＝17ms，offset(2)＝34ms，因此50ms的CG周期时段内包括三个小周期时段：0～17ms；17～34ms；34～50ms。
此外，若接入网设备通过激活命令为终端配置了一个K2，则每个小周期时段内包括一个传输时机，参见图3B所示。此种情形下，终端可以根据K2和offset(0)确定该套传输时机中首个传输时机(即第一个小周期时段内的传输时机)的位置，以及根据K2和offset(1)确定该套传输时机中第二个传输时机(即第二个小周期时段内的传输时机)的位置，以及根据K2和offset(2)确定该套传输时机中第三个传输时机(即第三个小周期时段内的传输时机)的位置。
若接入网设备通过激活命令为终端配置了n个K2(n为大于1的整数)，则每个小周期时段内包括n个传输时机，参见图3C所示。此种情形下，以n个K2分别为K2_1、K2_2和K2_3为例，终端可以根据K2_1和offset(0)确定该套传输时机中首个传输时机(即第一个小周期时段内的首个传输时机)的位置，根据K2_2和offset(0)确定该套传输时机中第二个传输时机(即第一个小周期时段内的第二个传输时机)的位置，根据K2_3和offset(0)确定该套传输时机中第三个传输时机(即第一个小周期时段内的第三个传输时机)的位置。以及，终端可以根据K2_1和offset(1)确定第二个小周期时段内的首个传输时机的位置，根据K2_2和offset(1)确定第二个小周期时段内的第二个传输时机的位置，以此类推，不再赘述。
可以理解的是，在图3C所示意的情形中，接入网设备也可以只配置了K2_1，未配置K2_2和K2_3，此时可以默认每个小周期时段内的传输时机位于连续的时隙或连续的上行时隙。
(2)配置方式2B
接入网设备可以为终端配置CG周期和周期列表(cycle list)。举个例子，数据帧的帧率为60FPS(即数据帧的传输周期约为16.67ms)，则CG周期可以配置为50ms，cycle list可以配置为[17 17 16]，即cycle(0)＝17ms，cycle(1)＝17ms，cycle(2)＝16ms，因此50ms的CG周期时段内包括三个小周期时段：0～17ms；17～34ms；34～50ms。其中，一个小周期时段内可以包括一个或多个传输时机，比如参照图3B和图3C的描述。
(3)配置方式3B
接入网设备可以为终端配置CG周期和TDRA表(table)，TDRA表中的每一行可以包括一个或多个K2(以及SLIV)。举个例子，数据帧的帧率为60FPS(即数据帧的传输周期约为16.67ms)，则CG周期可以配置为50ms，激活命令中选取的TDRA行包括多个K2，比如参见图3D所示，多个K2为[0 5 10 17 22 27 34 39 44]，则表示一个CG周期时段(50ms)内，多个传输时机的起始位置分别为0ms、5ms、10ms、17ms、22ms、27ms、34ms、39ms、44ms。
根据上述相关技术特征的描述可以看出，接入网设备可以配置多个传输时机来传输一个数据帧。若这多个传输时机所能承载的数据量小于数据帧的数据量，则需要动态调度数据帧剩余的数据，从而会引入额外的传输时延。为了降低传输时延，一种可能的方式为，接入网设备预估数据帧的最大数据量，并按照预估的数据帧的最大数据量来配置这多个传输时机。此种情形下，当实际传输的数据帧的数据量较小时，可能会导致这多个传输时机中的部分传输时机未被使用，从而造成传输资源的浪费。
基于此，本申请实施例提供一种通信方法，用于实现终端通知接入网设备不使用的传输时机，以便于接入网设备将不使用的资源分配给其它终端，提高资源利用率。
图4为本申请实施例提供的通信方法所对应的流程示意图。图4中以终端和接入网设备作为该交互示意的执行主体为例来示意该方法，但本申请并不限制该交互示意的执行主体。例如，图4中的终端也可以是应用于终端的模块例如芯片、芯片系统、或处理器，还可以是能实现全部或部分终端功能的逻辑节点、逻辑模块或软件；图4中的接入网设备也可以是应用于接入网设备的模块例如芯片、芯片系统、或处理器，还可以是能实现全部或部分接入网设备功能的逻辑节点、逻辑模块或软件。
如图4所示，该方法包括如下步骤：
S401，接入网设备向终端发送第一配置信息，第一配置信息用于配置承载指示信息的第一传输时机和指示信息作用的第一时段，指示信息用于指示第一时段内使用或不使用的传输时机。
示例性地，第一传输时机可以位于第一时段内，或者第一传输时机也可以位于第一时段之外。当第一传输时机位于第一时段内时，第一时段内使用或不使用的传输时机可以不包括第一传输时机，也就是说，可以默认第一传输时机为使用的传输时机。此外，第一传输时机可以位于第一时段内使用或不使用的传输时机之前。
第一配置信息配置第一传输时机和第一时段的实现方式有多种，比如实现方式1和实现方式2。
(1)实现方式1
在实现方式1中，接入网设备可以向终端发送第二配置信息，第二配置信息用于配置多个传输时机。其中，多个传输时机可以对应相同的CG，即多个传输时机属于同一套传输时机，对应同一CG索引；或者，多个传输时机也可以对应不同的CG，即多个传输时机属于不同套传输时机，对应两个或两个以上CG索引。具体的配置方式可以参照前文(比如配置方式1A至配置方式3A、配置方式1B至配置方 式3B)，本申请实施例对此不做限定。以及，接入网设备还可以向终端发送第一配置信息，第一配置信息用于配置第一传输时机和第一时段。
也就是说，接入网设备可以采用前文所描述的配置方式为终端配置多个传输时机，并额外通过第一配置信息为终端配置多个传输时机中的哪个(些)传输时机为第一传输时机，以及指示信息作用的第一时段。其中，第一配置信息和第二配置信息可以承载于同一消息，或者也可以承载于不同消息。
(1.1)比如，第一配置信息包括第一时段的时长，第一时段可以周期性出现，参见图5A所示的第一时段1、第一时段2和第一时段3。示例性地，首个第一时段的起始位置可以为接入网设备为终端配置的多个传输时机中首个传输时机的起始位置。
可选地，第一配置信息还包括信息1，信息1用于指示第一时段内的哪个传输时机为第一传输时机，比如信息1用于指示第一时段内的首个传输时机为第一传输时机，或者用于指示第一时段内的其它传输时机为第一传输时机。或者，第一配置信息也可以不包括信息1，可以由协议预先定义第一时段内的哪个传输时机为第一传输时机，或者接入网设备和终端预先约定第一时段内的哪个传输时机为第一传输时机。
以第一时段内的首个传输时机为第一传输时机为例，参见图5A所示，终端可以在传输时机0上发送指示信息1，指示信息1用于指示第一时段1内使用或不使用的传输时机；终端可以在传输时机3上发送指示信息2，指示信息2用于指示第一时段2内使用或不使用的传输时机；以此类推。其中，每个第一时段(比如图5A中的第一时段1、第二时段2、第一时段3)的时长均等于接入网设备配置的第一时段的时长。
(1.2)又比如，第一配置信息包括循环周期和多个偏移量a。举个例子，循环周期为50ms，多个偏移量a分别为[0 17 34]，则表示相邻两个偏移量a之间的范围即为第一时段，即一个循环周期内包括三个第一时段，分别为：0～17ms；17～34ms；34～50ms。再举个例子，循环周期为50ms，多个偏移量a分别为[0 22 39]，则表示相邻两个偏移量a之间的范围即为第一时段，即一个循环周期内包括三个第一时段，分别为：0～22ms；22～39ms；39～50ms。
可选地，第一配置信息还包括信息1，信息1用于指示第一时段内的哪个传输时机为第一传输时机，比如信息1用于指示第一时段内的首个传输时机为第一传输时机。
此种情形下，以循环周期为50ms，多个偏移量a分别为[0 17 34]为例，参见图5B所示，终端可以在传输时机0上发送指示信息1，指示信息1用于指示第一时段1内使用或不使用的传输时机；终端可以在传输时机3上发送指示信息2，指示信息2用于指示第一时段2内使用或不使用的传输时机；以此类推。其中，一个循环周期内不同第一时段的时长可以不同，比如图5B中第一时段1的时长为17ms，第一时段2的时长为17ms、第一时段3的时长为16ms。
或者，第一配置信息包括循环周期和多个偏移量b，多个偏移量b分别为[0 5 10 17 22 27 34 39 44]，进一步地，第一配置信息还包括偏移量分组(offset group)信息，偏移量分组信息用于指示哪些偏移量b为一个分组，比如偏移量分组信息指示[0 5 10]为第一组，[17 22 27]为第二组，[34 39 44]为第三组，则表示相邻的两个分组之间的范围即为第一时段，即一个循环周期内包括三个第一时段，分别为：0～17ms；17～34ms；34～50ms。
(1.3)又比如，第一配置信息包括循环周期和多个周期值。举个例子，循环周期为50ms，多个周期值分别为[17 17 16]，则表示一个循环周期内包括三个小周期时段，分别为：0～17ms；17～34ms；34～50ms；每个小周期时段即为一个第一时段。可选地，第一配置信息还包括信息1，信息1用于指示第一时段内的哪个传输时机为第一传输时机，比如信息1用于指示第一时段内的首个传输时机为第一传输时机。此种情形下，可以参照图5B的描述。
再举个例子，循环周期为50ms，多个周期值分别为[22 17 11]，则表示一个循环周期内包括三个小周期时段，分别为：0～22ms；22～39ms；39～50ms；每个小周期时段即为一个第一时段。
(1.4)又比如，第二配置信息配置的多个传输时机对应多个CG索引，第一配置信息可以配置多个CG索引中的至少一个CG索引对应的传输时机为第一传输时机，比如第一配置信息包括至少一个CG索引。
进一步地，在一个示例中，第一配置信息还可以配置相邻的两个第一传输时机之间的时段为第一时段。其中，相邻的两个第一传输时机之间的时段可以为：前一个传输时机的起始位置与后一个传输时机的起始位置之间的时段，此时第一传输时机位于第一时段内；或者，相邻的两个第一传输时机之间的时 段可以为：前一个传输时机的结束位置与后一个传输时机的起始位置之间的时段，此时第一传输时机位于第一时段之外。
此种情形下，参见图5C所示，第二配置信息配置的多个传输时机对应的多个CG索引为CG1、CG2和CG3，若第一配置信息配置CG1对应的传输时机为第一传输时机，则终端可以在传输时机0上发送指示信息1，指示信息1用于指示第一时段1内使用或不使用的传输时机；终端可以在传输时机3上发送指示信息2，指示信息2用于指示第一时段2内使用或不使用的传输时机；以此类推。
在又一个示例中，第一配置信息还可以配置持续时间(duration)，此种情形下，第一时段的起始位置可以为第一传输时机的起始位置，或者也可以是第一传输时机的起始位置偏移第一偏移量(参见下文)后的位置，第一时段的时长即为持续时间。
此外，在实现方式1中，第一配置信息和第二配置信息可以相互关联(或者说指示信息和多个传输时机可以相互关联)，具体的关联方式有多种。比如，第一配置信息包括第二配置信息所配置的多个传输时机对应的CG索引，此种情形下，第一配置信息和第二配置信息可以承载于同一消息，或者也可以承载于不同消息。又比如，第二配置信息所配置的多个传输时机属于一套传输时机，则第一配置信息和第二配置信息可以均承载在该套传输时机对应的CG-Config字段中。又比如，若接入网设备通过第二配置信息为终端配置了多套传输时机(即第二配置信息包括多套传输时机的配置信息)，则这多套传输时机中的每套传输时机的配置信息中可以增加一个额外的信息(称为信息2)，信息2用于指示该套传输时机与指示信息关联。又比如，若接入网设备通过第二配置信息为终端配置了多套传输时机，则这多套传输时机中的每套传输时机的配置信息中可以增加一个额外的信息(称为信息3)，信息3用于指示该套传输时机与哪些传输时机上承载的指示信息关联。
(2)实现方式2
在实现方式2中，第一配置信息用于配置多个传输时机，这多个传输时机属于同一套传输时机，这多个传输时机对应的CG周期时段包括第一时段，CG周期时段内的传输时机包括第一传输时机。也就是说，接入网设备可以通过为终端配置多个传输时机，来隐式配置多个传输时机中的哪个(些)传输时机为第一传输时机，以及指示信息作用的第一时段。
(2.1)比如，第一配置信息包括CG周期和周期列表。举个例子，CG周期可以配置为50ms，cycle list可以配置为[17 17 16]，即cycle(0)＝17ms，cycle(1)＝17ms，cycle(2)＝16ms，因此50ms的CG周期时段内包括三个小周期时段：0～17ms；17～34ms；34～50ms。
此种情形下，终端可以根据第一配置信息，确定CG周期时段内的每个小周期时段即为一个第一时段。可选地，第一配置信息还包括信息1，信息1用于指示第一时段内的哪个传输时机为第一传输时机；或者第一配置信息不包括信息1，此时可以由协议预先定义第一时段内的哪个传输时机为第一传输时机，或者接入网设备和终端预先约定第一时段内的哪个传输时机为第一传输时机，具体可以参照图5B的描述。
(2.2)又比如，第一配置信息包括CG周期和偏移量列表。举个例子，CG周期可以配置为50ms，offset list可以配置为[0 17 34]，即offset(0)＝0ms，offset(1)＝17ms，offset(2)＝34ms，因此50ms的CG周期时段内包括三个小周期时段：0～17ms；17～34ms；34～50ms。
此种情形下，终端可以根据第一配置信息，确定CG周期时段内的每个小周期时段即为一个第一时段。可选地，第一配置信息还包括信息1，信息1用于指示第一时段内的哪个传输时机为第一传输时机；或者第一配置信息不包括信息1，此时可以由协议预先定义第一时段内的哪个传输时机为第一传输时机，或者接入网设备和终端预先约定第一时段内的哪个传输时机为第一传输时机，具体可以参照图5B的描述。
(2.3)又比如，第一配置信息包括CG周期和多个K2。举个例子，多个K2为[0 5 10 17 22 27 34 39 44]，则表示一个CG周期时段(50ms)内，多个传输时机的起始位置分别为0ms、5ms、10ms、17ms、22ms、27ms、34ms、39ms、44ms。进一步地，第一配置信息还可以包括分组信息，比如分组信息指示每三个K2为一组，则表示一个CG周期时段内包括三个小周期时段：0～17ms；17～34ms；34～50ms。可以理解的是，分组信息也可以是协议预先定义的，或者接入网设备和终端预先约定的。
此种情形下，终端可以根据第一配置信息，确定CG周期时段内的每个小周期时段即为一个第一时段。可选地，第一配置信息还包括信息1，信息1用于指示第一时段内的哪个传输时机为第一传输时机；或者第一配置信息不包括信息1，此时可以由协议预先定义第一时段内的哪个传输时机为第一传输时机， 或者接入网设备和终端预先约定第一时段内的哪个传输时机为第一传输时机，具体可以参照图5B的描述。
可以理解的是，上述第一配置信息可以承载于多种可能的信令，比如第一配置信息可以承载于物理层信令如DCI，或者高层信令如MAC CE或RRC信令，或者也可以是不同信令的组合，例如MAC CE或RRC信令配置候选集合(候选集合中的每个候选项都用于配置第一传输时机和第一时段)，DCI指示候选集合中的哪个候选项，进而终端可以根据该候选向确定第一传输时机和第一时段；或者，RRC信令配置候选集合，MAC CE指示集合中的哪个候选项；或者，RRC信令配置候选集合的集合，MAC CE指示具体是哪个候选集合，DCI指示该候选集合中的具体哪个候选项。
S402，终端在第一传输时机上发送指示信息；相应地，接入网设备在第一传输时机上接收指示信息。
示例性地，终端还可以在第一传输时机上发送数据，也就是说，第一传输时机可以承载指示信息和数据。此外，可选地，接入网设备在第一传输时机接收指示信息后，可以向终端反馈确认信息，确认信息表示接入网设备已接收到指示信息。
终端在第一传输时机上向接入网设备发送指示信息的方式可以有多种，比如终端可以向接入网设备发送上行控制信息(uplink control information，UCI)或者CG-UCI或者媒体接入控制(media access control，MAC)控制单元(control element，CE)，UCI或者CG-UCI或者MAC CE包括指示信息。
如上述所述，指示信息用于指示第一时段内使用或不使用的传输时机，具体的指示方式可以有多种，比如指示方式1、指示方式2和指示方式3。
(1)指示方式1
指示信息指示第一时段内不使用的传输时机的数量。此种情形下，第一时段内不使用的传输时机为连续的传输时机，且位于第一时段的后面。比如，指示信息指示第一时段内不使用的传输时机的数量为X，则第一时段内不使用的传输时机即为从第一时段内的最后一个传输时机往前的X个传输时机。参见图6A所示，X＝2，则表示第一时段内的最后两个传输时机为不使用的传输时机。
(2)指示方式2
指示信息包括比特位图，比特位图用于指示第一时段内的一个或多个使用或不使用的CG传输时机。示例性地，比特位图中的一个比特对应一个或多个传输时机，该比特的取值用于指示该比特对应的传输时机是否使用，比如该比特的取值为“0”，表示该比特对应的传输时机不使用，比特的取值为“1”，表示该比特对应的传输时机使用，或者反之。
比如，比特位图包括M个比特，M个比特对应N个传输时机，一种可能的对应方法为：比特位图中的第i(i＝1,2……M)个比特对应第(i-1)*int(N/M)+1到第i*int(N/M)个传输时机；或者，比特位图中的第i(i＝1,2……M)个比特对应第(M-i+1)*int(N/M)到第(M-i)*int(N/M)+1个传输时机。其中，int为取整符号，可以是向下取整。
此种情形下，比特位图的位宽(即比特位图所包括的比特的个数)取决于第一时段内的传输时机的个数。以比特位图中的一个比特对应一个传输时机为例，若第一传输时机位于第一时段之外，则比特位图的位宽等于第一时段内的传输时机的个数；若第一传输时机位于第一时段内，则比特位图的位宽等于第一时段内除第一传输时机以外的传输时机的个数。
举个例子，参见图6B所示，第一时段内包括7个传输时机(即传输时机0至传输时机6)，传输时机0为第一传输时机，则比特位图可以指示传输时机1至传输时机6使用或不使用。
若比特位图中的一个比特对应一个传输时机，则比特位图可以包括6个比特，比如6个比特中的第1个比特对应第一时段内的最后一个传输时机(即传输时机6)，第2个比特对应第一时段内的倒数第2个传输时机(即传输时机5)，以此类推。因此，若比特位图的取值为000000，则表示传输时机1至传输时机6均为不使用的传输时机，若比特位图的取值为000011，则表示传输时机3至传输时机6均为不使用的传输时机，传输时机1和传输时机2为使用的传输时机，其它可以参照处理，不再一一列举。
若比特位图中的一个比特对应多个传输时机，比如一个比特对应2个传输时机，则比特位图可以包括3个比特，比如3个比特中的第1个比特对应第一时段内的最后两个传输时机(即传输时机5和传输时机6)，第2个比特对应第一时段内的倒数第3和4个传输时机(即传输时机3和传输时机4)，第3个比特对应第一时段内的倒数第1和2个传输时机(即传输时机1和传输时机2)。因此，若比特位图的取值为000，则表示传输时机1至传输时机6均为不使用的传输时机，若比特位图的取值为001，则 表示传输时机3至传输时机6均为不使用的传输时机，传输时机1和传输时机2为使用的传输时机，其它可以参照处理，不再一一列举。
此外，当比特位图中的一个比特对应多个传输时机时，不同比特对应的传输时机的个数可以相同，或者也可以不同。比特位图中的每个比特对应的传输时机可以为协议预先定义的，或者也可以是接入网设备配置给终端的，比如接入网设备可以为终端配置多个传输时机分组，比特位图中的每个比特可以对应一个传输时机分组。其中，多个传输时机分组中的每个传输时机分组可以包括一个或多个传输时机，不同传输时机分组所包括的传输时机的个数可以相同，也可以不同。
(3)指示方式3
指示信息用于指示第二时段，第一时段包括第二时段，第一时段内使用或不使用的CG传输时机位于所述第二时段内。
示例性地，指示信息可以包括第一偏移量，第一偏移量用于确定第二时段；具体来说，第一偏移量用于确定第二时段的起始位置，第二时段的结束位置与第一时段的结束位置相同。比如，第一偏移量的单位可以为时间单位(如ms)，则第一时段的起始位置向后偏移第一偏移量即为第二时段的起始位置。又比如，第一偏移量的单位可以为传输时机的个数，假设第一偏移量为P个传输时机，则第一时段内第P+1个传输时机的起始位置即为第二时段的起始位置。
可以理解的是，第一偏移量可以是由终端灵活确定的，不同第一传输时机上发送的指示信息所携带的第一偏移量可以相同，或者也可以不同；或者，第一偏移量可以是接入网设备为终端配置的，此种情形下，指示信息可以无需包括第一偏移量。
作为一种可能的实现，第二时段内的传输时机可以默认均为不使用的传输时机。也就是说，可以仅通过第一偏移量来指示出第一时段内不使用的传输时机。
作为又一种可能的实现，指示信息还可以包括比特位图，比特位图中的一个比特用于指示一个或多个使用或不使用的传输时机。也就是说，可以通过第一偏移量和比特位图来指示第二时段内使用或不使用的传输时机。此种情形下，比特位图的位宽(即比特位图所包括的比特的个数)取决于第二时段内的传输时机的个数，比如比特位图中的一个比特对应一个传输时机，则比特位图的位宽等于第一时段内的传输时机的个数。
举个例子，参见图6C所示，第一时段内包括7个传输时机(即传输时机0至传输时机6)，传输时机0为第一传输时机。第一偏移量为3个传输时机(比如第一偏移量为“11”，表示3个传输时机)，则第二时段的起始位置为传输时机3的起始位置。
若比特位图中的一个比特对应一个传输时机，则比特位图可以包括4个比特，比如4个比特中的第1个比特对应第二时段内的最后一个传输时机(即传输时机6)，第2个比特对应第二时段内的倒数第2个传输时机(即传输时机5)，第3个比特对应第二时段内的倒数第3个传输时机(即传输时机4)，第4个比特对应第二时段内的倒数第4个传输时机(即传输时机3)。因此，若比特位图的取值为0000，则表示传输时机3至传输时机6均为不使用的传输时机，若比特位图的取值为0011，则表示传输时机6和传输时机5为不使用的传输时机，传输时机4和传输时机3为使用的传输时机，其它可以参照处理，不再一一列举。
若比特位图中的一个比特对应多个传输时机，比如一个比特对应2个传输时机，则比特位图可以包括2个比特，比如2个比特中的第1个比特对应第二时段内的最后两个传输时机(即传输时机5和传输时机6)，第2个比特对应第二时段内的倒数第3和4个传输时机(即传输时机3和传输时机4)。因此，若比特位图的取值为00，则表示传输时机3至传输时机6均为不使用的传输时机，若比特位图的取值为01，则表示传输时机6和传输时机5为不使用的传输时机，传输时机4和传输时机3为使用的传输时机，其它可以参照处理，不再一一列举。此外，当比特位图中的一个比特对应多个传输时机时，不同比特对应的传输时机的个数可以相同，或者也可以不同，每个比特对应的传输时机可以为协议预先定义的，或者也可以是接入网设备配置给终端的，具体不做限定。
通常情况下，接入网设备在第一传输时机上接收到指示信息，需要一定的处理时间方可解析出指示信息的内容，如果指示信息指示的不使用的传输时机包括第一传输时机的下一个传输时机，由于第一传输时机的下一个传输时机与第一传输时机之间的时间间隔较短(比如小于接入网设备的处理时间)，从而会导致接入网设备解析出指示信息后，来不及将下一个传输时机调度给其它终端。因此，采用指示方式3，指示信息可以包括第一偏移量，一方面，可以延迟指示信息的生效时间(即第二时段的起始时间)， 以给接入网设备预留足够的处理时间，便于接入网设备将不使用的传输时机调度给其它终端；另一方面，便于节省传输资源(比如在指示方式3中，第一偏移量包括7个传输时机，则第一偏移量可以为“111”，只需3个比特；若是不设置第一偏移量，假设比特位图中的一个比特对应一个传输时机，则比特位图需要再增加6个比特)。
可以理解的是，上述指示方式2和指示方式3中，比特位图的位宽是根据第一时段(或第二时段)内的传输时机的个数确定的。在其它可能的实现中，比特位图的位宽也可以是接入网设备为终端配置的。比如，指示信息包括比特位图(可选地，还包括第一偏移量)，第一配置信息用于配置比特位图的位宽(可选地，第一配置信息还用于配置第一传输时机)。此种情形下，比特位图对应的传输时机所在的时段即为第一时段；也就是说，第一时段是由比特位图的位宽决定的。
举个例子，第一配置信息配置比特位图的位宽为4。以比特位图中的一个比特对应一个传输时机为例，参见图6D所示，终端可以在传输时机0上发送指示信息1，指示信息1包括第一偏移量1和比特位图1(比如比特位图1为“1000”表示传输时机2使用，传输时机3至传输时机5不使用)，传输时机2至传输时机5所在的时段可以理解为第一时段1；以及，终端可以在传输时机6上发送指示信息2，指示信息2包括第一偏移量2和比特位图2(比如比特位图2为“1100”表示传输时机9和传输时机10使用，传输时机11和传输时机12不使用)，传输时机9至传输时机12所在的时段可以理解为第一时段2。
可以理解的是，接入网设备通过第一配置信息为终端配置了承载指示信息的传输时机后，终端可以在这些传输时机上均发送指示信息，或者也可能是在这些传输时机中的部分传输时机上发送指示信息。比如，在图6D所示意的情形中，传输时机0、传输时机3、传输时机6、传输时机9、传输时机12均可承载指示信息，而终端只在其中的传输时机0和传输时机6上发送了指示信息。
采用上述方法，终端可以根据第一配置信息，在第一传输时机上向接入网设备发送指示信息，以通知接入网设备不使用的传输时机，以便于接入网设备将不使用的资源分配给其它终端，提高资源利用率。此外，由于接入网设备是通过第一配置信息来统一配置第一传输时机和指示信息的作用的第一时段，因此，终端发送指示信息时，无需额外指示指示信息作用的第一时段，从而便于节省信令开销。
