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)。RAN 100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。
RAN 100可以为第三代合作伙伴计划(3rd generation partnership project，3GPP)相关的蜂窝系统，例如，4G、5G移动通信系统、或面向未来的演进系统(例如6G移动通信系统)。RAN 100还可以是开放式接入网(open RAN，O-RAN或ORAN)、云无线接入网络(cloud radio access network，CRAN)、或者WiFi系统。RAN 100还可以是以上两种或两种以上系统融合的通信系统。
RAN节点110，有时也可以称为RAN实体或接入节点等，构成通信系统的一部分，用以帮助终端实现无线接入。通信系统10中的多个RAN节点110可以为同一类型的节点，也可以为不同类型的节点。在一些场景下，RAN节点110和终端120的角色是相对的，例如，图1中网元120i可以是直升机或无人机，其可以被配置成移动基站，对于那些通过网元120i接入到RAN 100的终端120j来说，网元120i是基站；但对于基站110a来说，网元120i是终端。RAN节点110和终端120有时都称为通信装置，例如图1中网元110a和110b可以理解为具有基站功能的通信装置，网元120a-120j可以理解为具有终端功能的通信装置。
RAN节点还可以有不同的表述，例如接入网设备。本申请中后续若没有特殊说明，均采用接入网设备进行表述。
在一种可能的场景中，接入网设备可以是基站(base station)、演进型基站(evolved NodeB，eNodeB)、接入点(access point，AP)、发送接收点(transmission reception point，TRP)、下一代基站(next generation NodeB，gNB)、6G移动通信系统中的下一代基站、未来移动通信系统中的基站、或WiFi系统中的接入节点等。接入网设备可以是宏基站(如图1中的110a)、微基站或室内站(如图1中的110b)、中继节点或施主节点、或者是CRAN场景下的无线控制器。可选的，接入网设备还可以是服务器，可穿戴设备，车辆或车载设备等。例如，车辆外联(vehicle to everything，V2X)技术中的接入网设备可以为路侧单元(road side unit，RSU)。本申请中的接入网设备的全部或部分功能也可以通过在硬件上运行的软件功能来实现，或者通过平台(例如云平台)上实例化的虚拟化功能来实现。本申请中的接入网设备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。
在另一种可能的场景中，由多个接入网设备协作协助终端实现无线接入，不同接入网设备分别实现基站的部分功能。例如，接入网设备可以是集中式单元(central unit，CU)，分布式单元(distributed unit，DU)，CU-控制面(control plane，CP)，CU-用户面(user plane，UP)，或者无线单元(radio unit，RU)等。CU和DU可以是单独设置，或者也可以包括在同一个网元中，例如基带单元(baseband unit，BBU)中。RU可以包括在射频设备或者射频单元中，例如包括在射频拉远单元(remote radio unit，RRU)、有源天线处理单元(active antenna unit，AAU)或远程射频头(remote radio head，RRH)中。
在不同系统中，CU(或CU-CP和CU-UP)、DU或RU也可以有不同的名称，但是本领域的技术人员可以理解其含义。例如，在ORAN系统中，CU也可以称为O-CU(开放式CU)，DU也可以称为 O-DU，CU-CP也可以称为O-CU-CP，CU-UP也可以称为O-CU-UP，RU也可以称为O-RU。为描述方便，本申请中以CU，CU-CP，CU-UP、DU和RU为例进行描述。本申请中的CU(或CU-CP、CU-UP)、DU和RU中的任一单元，可以是通过软件模块、硬件模块、或者软件模块与硬件模块结合来实现。
终端也可以称为终端设备、用户设备(user equipment，UE)、移动台、移动终端等。终端可以广泛应用于各种场景，例如，设备到设备(device-to-device，D2D)、车物(vehicle to everything，V2X)通信、机器类通信(machine-type communication，MTC)、物联网(internet of things，IOT)、虚拟现实、增强现实、工业控制、自动驾驶、远程医疗、智能电网、智能家具、智能办公、智能穿戴、智能交通、智慧城市等。终端可以是手机、平板电脑、带无线收发功能的电脑、可穿戴设备、车辆、无人机、直升机、飞机、轮船、机器人、机械臂、智能家居设备等。本申请的实施例对终端的设备形态不做限定。
本申请中“向…(终端)发送信息”可以理解为该信息的目的端是终端，可以包括直接或间接的向终端发送信息。“从…(终端)接收信息”可以理解为该信息的源端是终端，可以包括直接或间接的从终端接收信息。信息在信息发送的源端和目的端之间可能会被进行必要的处理，例如格式变化等，但目的端可以理解来自源端的有效信息。本申请中类似的表述可以做类似的理解，在此不再赘述。
本申请实施例描述的通信系统以及业务场景是为了更加清楚的说明本申请实施例的技术方案，并不构成对于本申请实施例提供的技术方案的限定，本领域普通技术人员可知，随着网络架构的演变和新业务场景的出现，本申请实施例提供的技术方案对于类似的技术问题，同样适用。
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。
1)、半静态调度：
在半静态调度中，接入网设备可以为终端分配周期性的上行资源和/或下行资源。以上行资源为例，用于分配上行资源的半静态调度可以包括CG。CG是指在上行传输的过程中，接入网设备通过无线资源控制(radio resource control，RRC)信令和/或下行控制信息(downlink control information，DCI)分配周期性的上行资源，而后终端可以使用该周期性的上行资源中的一个或多个进行上行传输。
其中，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的资源或(physical uplink shared channel，PUSCH)资源或PUSCH机会或PUSCH时机或CG上行资源或CG PUSCH资源或CG PUSCH传输资源。
2)、UTO-UCI：
CG的一个周期(也称为CG周期)内可能包括多个PUSCH资源。CG的资源是固定的，而XR业务所需的资源会因数据量的变化而变化。例如，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，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，也可以是一些抽取出的环境特征信息，这些内容的数据量是可能发生变化的。因此，若为终端配置的CG的资源较多，则可能存在资源浪费的情况。
为避免资源浪费，终端可向接入网设备发送UTO-UCI，该UTO-UCI可指示未使用的PUSCH资源，这样，接入网设备可以将这部分资源重新分配给其他终端使用。例如，如图2所示，一个CG周期内包括4个PUSCH资源，终端可在第一个PUSCH资源上发送UTO-UCI，以便告知接入网设备本CG周期内的最后两个PUSCH资源未被使用。图2以在第一个PUSCH资源上发送UTO-UCI为例进行说明，应理解，终端也可通过其他PUSCH资源发送UTO-UCI，例如，终端通过其使用的每个PUSCH资源发送UTO-UCI。还应理解，UTO-UCI也可能替换为其它可能的描述，例如，XR-UCI或用于指示不使用的资源的UCI。
UTO-UCI可通过多种方式指示未使用的PUSCH资源。例如，UTO-UCI可通过比特位图指示一段时间内的每个PUSCH资源是否被使用。该一段时间例如一个CG周期或设定的时间段。UTO-UCI也可通过其他方式指示未使用的PUSCH资源，本申请对UTO-UCI的指示方式不作限定。
3)、时间单元，泛指时间的单位。示例性的，时间单元可以但不限于为子帧(subframe)、时隙(slot)、符号等。其中，所述符号可以是时域符号(例如，正交频分复用(orthogonal frequency division multiplexing，OFDM)符号)等。
4)、频率单元，泛指频率资源的单位。示例性的，频率单位可以但不限于资源块(resource block，RB)、资源块组(resource block group，RBG)等。
目前，接入网设备可为终端配置多个CG的资源。在这种情况下，UTO-UCI可指示该多个CG的资源是否被使用。示例性的，该多个CG包括CG1和CG2。CG1的资源配置和CG2的资源配置不同，例如，每个CG周期内，CG1的资源数和CG2的资源数不同；和/或，CG1的周期和CG2的周期不同。该UTO-UCI中的一个比特位图(bitmap)可用于指示CG1的资源和CG2的资源是否被使用。不同CG中的资源可能会发生时间上的重叠，如何指示时间上重叠的资源是否被使用，需要进一步的关注。
基于此，本申请实施例提供一种通信方法。图3为本申请实施例提供的通信方法所对应的流程示意图。图3中以第一装置和第二装置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，第一装置可以是终端，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；第二装置也可以是接入网设备，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3所示，该方法包括如下步骤：
S301，第一装置生成第一指示信息，第一指示信息包括第一比特位图，第一比特位图中的第一比特用于指示第一上行资源和第二上行资源不被使用，或者，用于指示第一上行资源和第二上行资源中的一个被使用。该第一比特可以为1个比特。
其中，第一上行资源为第一CG的资源，例如为第一CG的PUSCH资源；第二上行资源为第二CG的资源，例如为第二CG的PUSCH资源。第一上行资源和第二上行资源在时间上重叠，例如，第一上行资源和第二上行资源可以在时间上部分重叠，也可以在时间上完全重叠。另外，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，本申请对此不作限定。
示例性的，第一CG的资源和第二CG的资源可以是第二装置为第一装置配置的。例如，第二装置可以向第一装置发送第一配置信息和第二配置信息，第一配置信息用于配置第一CG的资源，第二配置信息用于配置第二CG的资源。其中，第一CG的一个周期内可包括多个资源，第二CG的一个周期内也可包括多个资源。第一配置信息和第二配置信息可以携带在同一消息中，也可以携带在不同的消息中，本申请对此不作限定。可选的，第一CG的资源和第二CG的资源可以是第二装置根据第一装置待发送数据的数据量确定的，例如，待发送数据的数据量与第一CG的资源和第二CG的资源的资源数量成正比。
在接收到第一配置信息和第二配置信息之后，第一装置可确定第一上行资源和第二上行资源在时间上重叠，并确定第一上行资源和第二上行资源的使用情况，从而生成第一指示信息。
一些示例中，第一装置确定第一上行资源和第二上行资源不被使用，从而生成指示第一上行资源和第二上行资源不被使用的第一指示信息。例如，当待发送的数据均可通过第一上行资源和第二上行资源之前的资源发送时，第一装置可确定第一上行资源和第二上行资源不被使用。
另一些示例中，第一装置确定第一上行资源和第二上行资源中的一个被使用，从而生成指示第一上行资源和第二上行资源中的一个被使用的第一指示信息。例如，当第一上行资源和第二上行资源之前的资源不足以发送完待发送的数据时，第一装置可确定第一上行资源和第二上行资源中的一个被使用。当第一上行资源和第二上行资源中的一个被使用时，第一装置可按照设定规则选择第一上行资源和第二上行资源中的一个发送上行数据。该设定规则例如为选择时间上重叠的资源中优先级最高的资源来发送上行数据。例如，当第一上行资源和第二上行资源中的一个被使用，且第一上行资源的优先级高于第二上行资源的优先级时，第一装置可选择第一上行资源来发送上行数据。
如前所述，第一比特用于指示第一上行资源和第二上行资源不被使用，或者，用于指示第一上行资源和第二上行资源中的一个被使用。具体的指示方式可有多种，例如，指示方式1和指示方式2。
(1)指示方式1：
第一比特用于指示第一上行资源和第二上行资源不被使用。可选的，当第一比特的取值为值#1时，指示第一上行资源和第二上行资源不被使用。值#1例如为0或1，下面以值#1为0为例进行说明。
例如，如图4A所示，第一上行资源为CG1的资源5，第二上行资源为CG2的资源6。第一装置使用如下资源发送上行数据：CG1的资源2和资源4，以及CG2的资源1和资源3。第一比特可为第一比特位图中的第5个比特，该比特的取值为0，表示资源5和资源6不被使用。
(2)指示方式2：
第一比特用于指示第一上行资源和第二上行资源中的一个被使用。可选的，当第一比特的取值为值#2时，指示第一上行资源和第二上行资源中的一个被使用。值#2例如为1或0。值#2可与值#1不同，例如，值#1为0，值#2为1，或者反之。下面以值#2为1为例进行说明。
例如，如图4B所示，第一上行资源为CG1的资源1，第二上行资源为CG2的资源2。第一装置使用如下资源发送上行数据：资源1和资源2中的一个，CG1的资源3，以及CG2的资源4。第一比特可为第一比特位图中的第1个比特，该比特的取值为1，表示资源1和资源2中的一个被使用。
一些可能的方式中，第一比特位图还可指示以下资源是否被使用：第一CG的资源中除第一上行资源之外的一个或多个资源，和/或第二CG的资源中除第二上行资源之外的一个或多个资源。也就是说，第一比特位图还可指示第一CG的资源和第二CG的资源中在时间上不重叠的一个或多个资源是否被使用。
可选的，第一比特位图中的一个比特可对应一个或多个资源，该比特的取值用于指示该比特对应的资源是否被使用，比如该比特的取值为0，表示该比特对应的资源不被使用，该比特的取值为1，表示该比特对应的资源被使用，或者反之。其中，当某一比特指示第一CG的资源和第二CG的资源中在时间上重叠的资源是否被使用时，该比特对应在时间上重叠的多个资源，例如，第一比特对应2个资源，即第一上行资源和第二上行资源。当某一比特指示第一CG的资源和第二CG的资源中在时间上不重叠的资源是否被使用时，该比特可对应一个资源。第一比特位图中，各个比特的顺序可以是根据各个比特对应的资源的开始时间确定的，例如，某一比特对应的PUSCH资源的开始时间越早，该比特在第一比特位图中的位置越靠前。
例如，仍以图4A为例，第一比特位图可包括5个比特，第一比特位图中的第1至4个比特分别对应于CG2的资源1、CG1的资源2、CG2的资源3和CG1的资源4，第一比特位图中的第5个比特对应于CG1的资源5和CG2的资源6。当第一比特位图取值为11110时，表示资源1至资源4被使用，资源5和资源6不被使用。
还例如，仍以图4B为例，第一比特位图可包括5个比特，第一比特位图中的第1个比特对应于CG1的资源1和CG2的资源2，第一比特位图中的第2至5个比特分别对应于CG1的资源3、CG2的资源4、CG1的资源5和CG2的资源6。当第一比特位图取值为11100时，表示资源1和资源2中的一个被使用，资源3和资源4被使用，资源5和资源6不被使用。
S302：第一装置输出第一指示信息。相应的，第二装置接收第一指示信息。
一些可能的方式中，第一装置可为终端内部的模块，例如，芯片。第一装置在生成第一指示信息之后，可将第一指示信息输出至终端中的另一个模块，例如，射频模块。然后，终端的另一个模块可向第二装置发送第一指示信息。
另一些可能的方式中，第一装置可向第二装置发送第一指示信息。在这种情况下，第一装置可为终端，第二装置可为接入网设备。
可以理解的是，上述第一指示信息可以承载于多种可能的信令，例如，承载于UCI中，该UCI可为CG-UCI或者UTO-UCI。
在接收到第一指示信息后，第二装置可根据第一指示信息中的第一比特确定第一上行资源和第二上行资源的使用情况。例如，当第一比特用于指示第一上行资源和第二上行资源不被使用时，第二装置可确定第一上行资源和第二上行资源不被使用，从而可将第一上行资源和/或第二上行资源分配给其它终端，提高资源利用率。还例如，当第一比特用于指示第一上行资源和第二上行资源中的一个被使用时，第二装置可根据设定规则确定第一上行资源和第二上行资源中哪个资源被使用，哪个资源未被使用，从而可将未被使用的资源分配给其它终端，提高资源利用率。其中，设定规则的具体内容可参考S301，此处不再赘述。
通过图3所示方法，当第一CG的第一上行资源和第二CG的第二上行资源在时间上重叠时，第一装置通过1个比特，即可指示第一上行资源和第二上行资源不被使用，或者，指示第一上行资源和第二 上行资源中的一个被使用，从而可减少信令开销，节约传输资源。
并且，该方法约定了第一比特位图中比特的数量以及各比特与所指示的资源之间的对应关系，从而可避免因第一装置和第二装置对第一比特位图中的比特数量理解不一致而产生的错误译码，也避免了因第一装置和第二装置对各比特与所指示的资源之间的对应关系理解不一致而产生的错误译码。另外，通过该方法，第一装置无需对在时间上重叠的PUSCH资源进行排序，从而可降低第一装置的实现复杂度，降低对第一装置的能力的要求。
应理解，图3所示方法以在时间上重叠的资源为两个资源为例进行说明，在实际使用时，在时间上重叠的资源也可以为两个以上的资源，此时，图3所示方法仍适用。
下面以在时间上重叠的资源包括第一上行资源、第二上行资源和第三上行资源为例进行说明。其中，第三上行资源为第三CG的资源，第三上行资源与第一上行资源和第二上行资源中的至少一个在时间上重叠。另外，第三上行资源与第一上行资源和第二上行资源中的至少一个在频域上可以重叠，也可以不重叠，本申请对此不作限定。
在这种情况下，第一比特还可用于指示第一上行资源、第二上行资源和第三上行资源不被使用，或者，还可用于指示第一上行资源、第二上行资源和第三上行资源中的一个被使用。第一比特的指示方式可参考S301中的指示方式1和指示方式2，只是将第一上行资源和第二上行资源替换为第一上行资源、第二上行资源和第三上行资源，重复之处不再赘述。
第三上行资源与第一上行资源和第二上行资源之间的关系可有多种，例如，关系1和关系2。
(1)关系1：第三上行资源与第一上行资源和第二上行资源在时间上均重叠。例如，如图4C所示，第一上行资源为CG1的资源5，第二上行资源为CG2的资源4，第三上行资源为CG3的资源6。资源6与资源4和资源5在时间上均重叠。
(2)关系2：第三上行资源与第一上行资源和第二上行资源中的一个在时间上重叠。可选的，第一上行资源和第二上行资源中，与第三上行资源重叠的资源用于传输上行数据。例如，如图4D所示，第一上行资源为CG1的资源5，第二上行资源为CG2的资源4，第三上行资源为CG3的资源6。资源5和资源6在时间上重叠，但资源4和资源6在时间上不重叠。其中资源5用于传输上行数据。
需要说明的是，第三上行资源可为一个或多个资源。示例性的，当第三上行资源为一个资源时，第三上行资源可为一个CG中的资源；当第三上行资源为多个资源时，第三上行资源可为多个CG中的资源，且每个CG中的第三上行资源均与第一上行资源和第二上行资源中的至少一个在时间上重叠。另外，当第三上行资源为多个资源时，该多个资源与第一上行资源和第二上行资源之间的关系可均为关系1，也可以均为关系2，或者，该多个资源中的一部分资源与第一上行资源和第二上行资源之间的关系为关系1，该多个资源中的另一部分资源与第一上行资源和第二上行资源之间的关系为关系2。
通过该方法，若第一CG的第一上行资源和第二CG的第二上行资源在时间上重叠，且第三CG的第三上行资源与第一上行资源和第二上行资源中的至少一个在时间上重叠，则第一装置通过1个比特，即可指示第一上行资源、第二上行资源和第三上行资源不被使用，或者，指示第一上行资源、第二上行资源和第三上行资源中的一个被使用，从而可进一步减少信令开销，节约传输资源。
一些可能的方式中，若上行资源#A与第一上行资源和第二上行资源中的一个在时间上重叠，并且，第一上行资源和第二上行资源中，与上行资源#A不重叠的资源用于传输上行数据，则第一比特位图中的第一比特用于指示第一上行资源和第二上行资源中的一个被使用，第一比特位图中的比特#A用于指示上行资源#A是否被使用。例如，如图4D所示，第一上行资源为CG1的资源5，第二上行资源为CG2的资源4，上行资源#A为CG3的资源6。资源5和资源6在时间上重叠，但资源4和资源6在时间上不重叠。若资源4用于传输上行数据，则第一比特位图中，第一比特用于指示资源4和资源5中的一个被使用，比特#A用于指示资源6是否被使用。通过该方式，第一装置通过2个比特，即可准确指示第一上行资源和第二上行资源中的一个被使用，以及指示上行资源#A是否被使用，从而可减少信令开销，节约传输资源。
本申请实施例提供另一种通信方法。图5为本申请实施例提供的通信方法所对应的流程示意图。图5中以第一装置和第二装置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，第一装置可以是终端，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；第二装置也可以是接入网设备，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5所示，该方法包括如下步骤：
S501：第一装置生成第二指示信息，第二指示信息包括第二比特位图，第二比特位图中的第二比特和第三比特用于指示第四上行资源和第五上行资源不被使用，或者，用于指示第四上行资源和第五上行资源中的一个被使用。该第二比特和第三比特可以均为1个比特。
其中，第四上行资源为第四CG的资源，例如为第四CG的PUSCH资源；第五上行资源为第五CG的资源，例如为第五CG的PUSCH资源。第四上行资源和第五上行资源在时间上重叠，例如，第四上行资源和第五上行资源可以在时间上部分重叠，也可以在时间上完全重叠。另外，第四上行资源和第五上行资源在频域上可以重叠，也可以不重叠，本申请对此不作限定。
示例性的，第四CG的资源和第五CG的资源可以是第二装置为第一装置配置的。配置的方式可参考S301中第一CG的资源和第二CG的资源的配置方式，只是将第一CG替换为第四CG，将第二CG替换为第五CG，此处不再赘述。在接收到第四CG的资源的配置信息和第四CG的资源的配置信息之后，第一装置可确定第四上行资源和第五上行资源在时间上重叠，并确定第四上行资源和第五上行资源的使用情况，从而生成第二指示信息。第一装置确定第四上行资源和第五上行资源的使用情况的方式，可参考S301中确定第一上行资源和第二上行资源的使用情况的方式，只是将第一上行资源替换为第四上行资源，将第二上行资源替换为第五上行资源，此处不再赘述。
如前所述，第二比特位图中的第二比特和第三比特用于指示第四上行资源和第五上行资源不被使用，或者，用于指示第四上行资源和第五上行资源中的一个被使用。具体的指示方式可有多种，例如，指示方式一、指示方式二和指示方式三。
(1)指示方式一：
第二比特和第三比特的值均为第一值时，指示第四上行资源和第五上行资源中的一个被使用。其中，第一值例如为1或0。下面以第一值为1为例进行说明。
例如，如图6A所示，第四上行资源为CG1的资源1，第五上行资源为CG2的资源2。第一装置使用如下资源发送上行数据：资源1和资源2中的一个，CG1的资源3，以及CG2的资源4。第二比特和第三比特分别为第二比特位图中的第1个比特和第2个比特，第二比特和第三比特的取值均为1，表示资源1和资源2中的一个被使用。
(2)指示方式二：
第二比特和第三比特的值均为第二值时，指示第四上行资源和第五上行资源不被使用。其中，第二值例如为0或1。第二值可与第一值不同，例如，第一值为1，第二值为0，或者反之。下面以第二值为0为例进行说明。
例如，如图6B所示，第四上行资源为CG1的资源5，第五上行资源为CG2的资源6。第一装置使用如下资源发送上行数据：CG1的资源1和资源3，以及CG2的资源2和资源4。第二比特和第三比特分别为第二比特位图中的第5个比特和第6个比特，第二比特和第三比特的取值均为0，表示资源5和资源6不被使用。
(3)指示方式三：
第四上行资源和第五上行资源在时间上重叠时，第一装置最多使用其中的一个资源进行上行传输。当第四上行资源和第五上行资源中的一个被使用时，第二比特可用于指示第四上行资源是否被使用，第三比特可用于指示第五上行资源是否被使用。可选的，当第二比特的取值为第一值时，指示第四上行资源被使用，当第二比特的取值为第二值时，指示第四上行资源不被使用；当第三比特的取值为第一值时，指示第五上行资源被使用，当第三比特的取值为第二值时，指示第五上行资源不被使用。第一值和第二值的具体内容可参考指示方式一和指示方式二，此处不再赘述。下面以第一值为1，第二值为0为例进行说明。
例如，如图6C所示，第四上行资源为CG1的资源1，第五上行资源为CG2的资源2。由于资源1的优先级高于资源2的优先级，第一装置使用如下资源发送上行数据：CG1的资源1和资源3，以及CG2的资源4。第二比特和第三比特可分别为第二比特位图中的第1个比特和第2个比特，第二比特的 取值为1，第三比特的取值均为0，表示资源1被使用，资源2不被使用。
一些可能的方式中，第二比特位图还可指示以下资源是否被使用：第四CG的资源中除第四上行资源之外的一个或多个资源，和/或第五CG的资源中除第五上行资源之外的一个或多个资源。也就是说，第二比特位图还可指示第四CG的资源和第五CG的资源中在时间上不重叠的一个或多个资源是否被使用。
可选的，第二比特位图中的一个比特可对应一个资源，该比特的取值用于指示该比特对应的资源是否使用，比如该比特的取值为0，表示该比特对应的资源不被使用，该比特的取值为1，表示该比特对应的资源被使用，或者反之。第二比特位图中，各个比特的顺序可以是根据各个比特对应的资源的开始时间确定的，例如，某一比特对应的PUSCH资源的开始时间越早，该比特在第二比特位图中的位置越靠前。
例如，仍以图6A为例，第二比特位图可包括6个比特，第二比特位图中的第1至6个比特分别对应于CG1的资源1、CG2的资源2、CG1的资源3、CG2的资源4、CG1的资源5和CG2的资源6。当第二比特位图取值为111100时，表示资源1和资源2中的一个被使用，资源3和资源4被使用，资源5和资源6不被使用。
还例如，仍以图6B为例，第二比特位图可包括6个比特，第二比特位图中的第1至6个比特分别对应于CG1的资源1、CG2的资源2、CG1的资源3、CG2的资源4、CG1的资源5和CG2的资源6。当第二比特位图取值为111100时，表示资源1至资源4被使用，资源5和资源6不被使用。
又例如，仍以图6C为例，第二比特位图可包括6个比特，第二比特位图中的第1至6个比特分别对应于CG1的资源1、CG2的资源2、CG1的资源3、CG2的资源4、CG1的资源5和CG2的资源6。当第二比特位图取值为101100时，表示资源1、资源3和资源4被使用，资源2、资源5和资源6不被使用。
目前，第一装置每次可发送的比特位图中比特数量是有限的。因此，第二比特位图中的第二比特和第三比特可能在不同的PUSCH资源中进行传输。其中，第二比特和第四上行资源对应，第三比特和第五上行资源对应。例如，第二比特可用于指示第四上行资源是否被使用，第三比特可用于指示第五上行资源是否被使用。这样，第二装置获知第四上行资源是否被使用的时刻，与第二装置获知第五上行资源是否被使用的时刻可能不同。
例如，如图6D为例所示，第四上行资源为CG1的资源4，第五上行资源为CG2的资源3。其中，资源4占用的时频域资源多于资源3占用的时频域资源。目前，各个比特的顺序可以是根据各个比特对应的资源的开始时间确定的。若第一装置每次可发送的比特位图中比特数量为3，则在第一装置第一次发送的比特位图中，3个比特可分别指示资源1至资源3是否被使用，在第一装置第二次发送的比特位图中，3个比特可分别指示资源4至资源6是否被使用。若资源4为不使用的资源，则第二装置需要在接收到第二次发送的比特位图之后，才能回收该资源，降低了资源的利用率。
鉴于此，在第二比特位图中，第二比特可在第三比特之前，也就是说，第二比特为第三比特的高位比特，或者说第三比特为第二比特的低位比特。并且，如下条件1至条件3中的一个条件可被满足。换句话说，当如下条件1至条件3中的一个条件被满足时，在第二比特位图中，第二比特可在第三比特之前。
(1)条件1：第四上行资源占用的时域资源多于第五上行资源占用的时域资源。这样，第二装置可尽早回收在时间上重叠的资源中占用的时域资源较多的资源，从而提高资源利用率。并且，由于回收的资源占用的时域资源较多，将其分配给其他终端时，可降低其他终端传输数据的时延。
一些示例中，若第四上行资源的起始时间单元和第五上行资源的起始时间单元相同，第四上行资源的结束时间单元在第五上行资源的结束时间单元之后，则条件1被满足。例如，如图6E所示，第四上行资源为CG1的资源3，第五上行资源为CG2的资源4。资源3的起始符号和资源4的起始符号相同，资源3的结束符号在资源4的结束符号之后，因此，条件1被满足。
另一些示例中，若第四上行资源的结束时间单元和第五上行资源的结束时间单元相同，第四上行资源的起始时间单元在第五上行资源的起始时间单元之前，则条件1被满足。例如，如图6F所示，第四上行资源为CG1的资源3，第五上行资源为CG2的资源4。资源3的起始符号在资源4的起始符号之 前，资源3的结束符号和资源4的结束符号相同，因此，条件1被满足。
又一些示例中，若第四上行资源的起始时间单元和第五上行资源的起始时间单元不同，第四上行资源的结束时间单元和第五上行资源的结束时间单元不同，第四上行资源占用的时域资源多于第五上行资源占用的时域资源，则条件1被满足。例如，如图6D所示，第四上行资源为CG1的资源4，第五上行资源为CG2的资源3，资源3的起始符号和资源4的起始符号不同，资源3的结束符号和资源4的结束符号不同，但资源4占用的时域资源多于资源3占用的时域资源，因此，条件1被满足。
(2)条件2：第四上行资源占用的频域资源多于第五上行资源占用的频域资源。这样，第二装置可尽早回收在时间上重叠的资源中占用的频域资源较多的资源，从而提高资源利用率。
一些示例中，若第四上行资源的起始频率单元和第五上行资源的起始频率单元相同，第四上行资源的结束频率单元在第五上行资源的结束频率单元之后，则第四上行资源包括的频率单元数多于第五上行资源包括的频率单元数，条件2被满足。例如，第四上行资源和第五上行资源在频域上连续，第四上行资源的起始频率单元和第五上行资源的起始频率单元均为资源块(resource block，RB)5，第四上行资源的结束频率单元为RB12，第五上行资源的结束频率单元为RB8，此时，条件2被满足。
另一些示例中，若第四上行资源的结束频率单元和第五上行资源的结束频率单元相同，第四上行资源的起始频率单元在第五上行资源的起始频率单元之前，则第四上行资源包括的频率单元数多于第五上行资源包括的频率单元数，条件2被满足。例如，第四上行资源和第五上行资源在频域上连续，第四上行资源的起始频率单元为RB5，第五上行资源的起始频率单元为RB9，第四上行资源的结束频率单元和第五上行资源的结束频率单元均为RB12，此时，条件2被满足。
又一些示例中，若第四上行资源的起始频率单元和第五上行资源的起始频率单元不同，第四上行资源的结束频率单元和第五上行资源的结束频率单元不同，第四上行资源占用的频域资源多于第五上行资源占用的频域资源，则第四上行资源包括的频率单元数多于第五上行资源包括的频率单元数，条件2被满足。例如，第四上行资源和第五上行资源在频域上连续，第四上行资源的起始频率单元为RB1，第五上行资源的起始频率单元为RB5，第四上行资源的结束频率单元为RB12，第五上行资源的结束频率单元为RB8，此时，条件2被满足。
再一种示例中，若第四上行资源和/或第五上行资源在频域上不连续，第四上行资源占用的频域资源多于第五上行资源占用的频域资源，则条件2被满足。例如，第四上行资源占用的RBG包括：RBG1至RBG4、以及RBG9至RBG12，第五上行资源占用的RBG包括：RBG9至RBG12，此时，条件2被满足。
(3)条件3：第四上行资源占用的时频域资源多于第五上行资源占用的时频域资源。这样，第二装置可尽早回收在时间上重叠的资源中占用的时频域资源较多的资源，从而提高资源利用率。
一种可能的方式中，当第四上行资源占用的时域资源多于第五上行资源占用的时域资源，并且，第四上行资源占用的频域资源多于第五上行资源占用的频域资源时，条件3被满足。第四上行资源占用的时域资源多于第五上行资源占用的时域资源的具体内容可参考对条件1的说明，第四上行资源占用的频域资源多于第五上行资源占用的频域资源的具体内容可参考对条件2的说明，此处不再赘述。
另一种可能的方式中，第四上行资源占用的时域资源多于第五上行资源占用的时域资源，或者，第四上行资源占用的频域资源多于第五上行资源占用的频域资源。并且，第四上行资源占用的时频域资源多于第五上行资源占用的时频域资源。一些示例中，第四上行资源占用的时域资源多于第五上行资源占用的时域资源，并且，第四上行资源占用的频域资源与第五上行资源占用的频域资源相同。例如，第四上行资源在时域上占用5个符号，在频域上占用4个RB；第五上行资源在时域上占用4个符号，在频域上占用4个RB，此时，条件3被满足。另一些示例中，第四上行资源占用的频域资源多于第五上行资源占用的频域资源，并且，第四上行资源占用的时域资源与第五上行资源占用的时域资源相同。例如，第四上行资源在时域上占用2个符号，在频域上占用10个RB；第五上行资源在时域上占用2个符号，在频域上占用4个RB，此时，条件3被满足。又一些示例中，第四上行资源占用的时域资源与第五上行资源占用的时域资源不同，第四上行资源占用的频域资源与第五上行资源占用的频域资源不同，并且，第四上行资源占用的时频域资源多于第五上行资源占用的时频域资源。例如，第四上行资源在时域上占用2个符号，在频域上占用10个RB；第五上行资源在时域上占用4个符号，在频域上占用4个RB，此时，条件3被满足。
可选的，当如下条件4至条件5中的一个条件被满足时，在第二比特位图中，第二比特也可在第三 比特之前。
(4)条件4：第四上行资源用于承载第二指示信息。这样，第二装置可尽早获知承载第二指示信息的上行资源被使用，从而可尽早对该上行资源进行译码，进而获知该第二指示信息指示的资源中不被使用的资源。
例如，如图6G所示，第四上行资源为CG2的资源3，第五上行资源为CG1的资源4。若资源3用于承载第二指示信息，则在第二比特位图中，与第四上行资源对应的第二比特在与第五上行资源对应的第三比特之前。
一些可能的方式中，条件4可单独使用，也就是说，只要满足条件4，在第二比特位图中，第二比特就在第三比特之前。
另一些可能的方式中，条件4也可与其他条件结合使用。例如，当第四上行资源占用的时域资源和第五上行资源占用的时域资源相同，和/或第四上行资源占用的频域资源和第五上行资源占用的时域资源相同时，若条件4被满足，则第二比特可在第三比特之前。
其中，若第四上行资源的起始时间单元和第五上行资源的起始时间单元相同，且第四上行资源的结束时间单元和第五上行资源的结束时间单元相同，则第四上行资源占用的时域资源和第五上行资源占用的时域资源相同。例如，第四上行资源的起始时间单元和第五上行资源的起始时间单元均为符号0，第四上行资源的结束时间单元和第五上行资源的结束时间单元均为符号2，则第四上行资源占用的时域资源和第五上行资源占用的时域资源相同。
第四上行资源占用的频域资源和第五上行资源占用的频域资源相同可有多种可能的方式，例如，方式1和方式2。
方式1：
第四上行资源和第五上行资源在频域上连续。若第四上行资源的起始频率单元和第五上行资源的起始频率单元相同，且第四上行资源的结束频率单元和第五上行资源的结束频率单元相同，则第四上行资源占用的频域资源和第五上行资源占用的频域资源相同。例如，第四上行资源的起始频率单元和第五上行资源的起始频率单元均为RB5，第四上行资源的结束频率单元和第五上行资源的结束频率单元均为RB8，则第四上行资源占用的频域资源和第五上行资源占用的频域资源相同。
方式2：
第四上行资源和第五上行资源在频域上不连续。第四上行资源占用的频域资源和第五上行资源占用的频域资源相同。例如，第四上行资源占用的频域资源和第五上行资源占用的频域资源均为：RBG0至RBG4，以及RBG9至RBG12，则第四上行资源占用的频域资源和第五上行资源占用的频域资源相同。
(5)条件5：第四CG的索引小于第五CG的索引。并且，第四上行资源占用的时域资源和第五上行资源占用的时域资源相同，和/或第四上行资源占用的频域资源和第五上行资源占用的时域资源相同。其中，第四上行资源占用的时域资源和第五上行资源占用的时域资源相同，和第四上行资源占用的频域资源和第五上行资源占用的时域资源相同的具体内容可参考对条件4中的说明，此处不再赘述。
例如，如图6H所示，第四上行资源为CG1的资源3，第五上行资源为CG2的资源4。CG1的索引小于CG2，因此，在第二比特位图中，与第四上行资源对应的第二比特在与第五上行资源对应的第三比特之前。
应理解，当在第二比特位图中，第二比特在第三比特之前时，第二比特与第三比特可为相邻的比特，也可为不相邻的比特。
一些示例中，在第二比特位图中，用于指示在时间上不重叠的资源的比特的位置是根据该比特对应的资源的开始时间确定的，比如某一比特对应的PUSCH资源的开始时间越早，该比特在第二比特位图中的位置越靠前。例如，以图6G为例，第四上行资源为CG2的资源3，第五上行资源为CG1的资源4。资源3用于传输第二指示信息。第二比特位图中第1至6个比特分别对应于：CG2的资源1、CG1的资源2、CG2的资源3、CG1的资源4、CG1的资源5和CG2的资源6。此时，在第二比特位图中，第二比特和第三比特为相邻的比特，分别为第二比特位图中的第3个比特和第4个比特。
另一些示例中，当满足条件1至条件4中的一个条件时，在第二比特位图中，用于指示第四CG的资源是否被使用的比特可位于用于指示第五CG的资源是否被使用的比特之前。例如，仍以图6G为例，第四上行资源为CG2的资源3，第五上行资源为CG1的资源4。资源3用于承载第二指示信息。第二比特位图中第1至6个比特分别对应于：CG2的资源1、CG2的资源3、CG2的资源6、CG1的资源2、 CG1的资源4和CG1的资源5。此时，在第二比特位图中，第二比特和第三比特为不相邻的比特，分别为第二比特位图中的第2个比特和第5个比特。
S502：第一装置输出第二指示信息。相应的，第二装置接收第二指示信息。
其中，第一装置输出第二指示信息的方式可参考S302中的第一装置输出第一指示信息，只是将第一指示信息替换为第二指示信息，此处不再赘述。
可以理解的是，上述第二指示信息可以承载于多种可能的信令，例如，承载于UCI中，该UCI例如为CG-UCI或者UTO-UCI。
在接收到第二指示信息后，第二装置可根据第二指示信息中的第二比特和第三比特确定第一上行资源和第二上行资源的使用情况，确定的方式可参考S302中，第二装置可根据第一指示信息中的第一比特确定第一上行资源和第二上行资源的使用情况的方式，只是将第一指示信息中的第一比特替换为第二指示信息中的第二比特和第三比特，此处不再赘述。
通过图5所示方法，当第四CG的第四上行资源和第五CG的第五上行资源在时间上重叠时，第一装置可通过2个比特指示第四上行资源和第五上行资源不被使用，或者，指示第四上行资源和第五上行资源中的一个被使用。该方法约定了第二比特位图中比特的数量以及各比特与所指示的资源之间的对应关系，从而可避免因第一装置和第二装置对第二比特位图中的比特数量理解不一致而产生的错误译码，也避免了因第一装置和第二装置对各比特与所指示的资源之间的对应关系理解不一致而产生的错误译码。另外，通过该方法，第一装置无需对在时间上重叠的PUSCH资源进行排序，从而可降低第一装置的实现复杂度，降低对第一装置的能力的要求。
应理解，图5所示方法以在时间上重叠的资源为两个资源为例进行说明，在实际使用时，在时间上重叠的资源也可以为两个以上的资源，此时，图5所示方法仍适用。
下面以在时间上重叠的资源包括第四上行资源、第五上行资源和第六上行资源为例进行说明。其中，第六上行资源为第六CG的资源，第六上行资源与第四上行资源和第五上行资源中的至少一个在时间上重叠。另外，第六上行资源与第四上行资源和第五上行资源中的至少一个在频域上可以重叠，也可以不重叠，本申请对此不作限定。
第六上行资源的具体内容，以及第六上行资源与第四上行资源和第五上行资源之间的关系，可分别参考图3所示方法中对第三上行资源，以及关系1至关系2的说明，只是将第一上行资源替换为第四上行资源，将第二上行资源替换为第五上行资源，将第三上行资源替换为第六上行资源，此处不再赘述。
一些示例中，第二比特位图中的第二比特、第三比特和第四比特用于指示第四上行资源、第五上行资源和第六上行资源不被使用，或者，用于指示第四上行资源、第五上行资源和第六上行资源中的一个被使用，指示的方式可参考S501中的指示方式一至指示方式三。例如，第二比特、第三比特和第四比特的值均为第一值时，指示第四上行资源、第五上行资源和第六上行资源中的一个被使用。还例如，第二比特、第三比特和第四比特的值均为第二值时，指示第四上行资源、第五上行资源和第六上行资源不被使用。又例如，当第四上行资源、第五上行资源和第六上行资源中的一个被使用时，第二比特可用于指示第四上行资源是否被使用，第三比特可用于指示第五上行资源是否被使用，第四比特用于指示第六上行资源是否被使用。
可选的，在第二比特位图中，第二比特、第三比特和第四比特的先后顺序可根据条件1至条件5中的一个或多个条件确定。其中，第二比特可用于指示第四上行资源是否被使用，第三比特可用于指示第五上行资源是否被使用，第四比特可用于指示第六上行资源是否被使用。例如，若各资源占用的时域资源从大到小的顺序为：第四上行资源、第六上行资源和第五上行资源，则在第二比特位图中，第二比特位于第四比特之前，第四比特位于第三比特之前。还例如，若各资源占用的频域资源从大到小的顺序为：第四上行资源、第六上行资源和第五上行资源，则在第二比特位图中，第二比特位于第四比特之前，第四比特位于第三比特之前。又例如，条件4和条件5可相互结合。第二比特位图中，用于承载第二指示信息的资源对应比特位于其他在时间上重叠的资源对应的比特之前，其他在时间上重叠的资源对应的比特之间的先后顺序可根据条件5确定。例如，如图6I所示，第四上行资源为CG2的资源4，第五上行资源为CG1的资源5，第六上行资源为CG3的资源6。其中，资源4、资源5和资源6占用的时域资源相同，资源4用于传输第二指示信息，CG1的索引小于CG3的索引。此时，在第二比特位图中，第二比特位于第三比特之前，第三比特位于第四比特之前。
通过该示例，若第四CG的第四上行资源和第五CG的第五上行资源在时间上重叠，且第六CG的第六上行资源与第四上行资源和第五上行资源中的至少一个在时间上重叠，则第一装置通过多个比特，准确指示第四上行资源、第五上行资源和第六上行资源不被使用，或者，指示第四上行资源、第五上行资源和第六上行资源中的一个被使用。
