一种资源配置方法及通信装置
相关申请的交叉引用
本申请要求在2019年03月27日提交中国专利局、申请号为201910239483.3、申请名称为“一种资源配置方法及通信装置”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，尤其涉及一种资源配置方法及通信装置。
背景技术
在新无线(new radio，NR)***中，有两种调度机制，一种是动态调度机制，即终端装置每次有数据传输时，请求网络装置分配资源，网络装置根据终端装置的请求，为终端装置分配资源。这种方式由于终端装置每次有数据传输时，都需要等待网络装置开始分配资源，所以时延较长，即动态调度机制不适合低时延业务。另一种是免授权配置调度(configured grant scheduling)，也就是长期演进(Long Term Evolution，LTE)***中的半静态调度(semi-persistent scheduling，SPS)机制。即网络装置主动为终端装置配置资源，这样终端装置有数据传输时就可以直接在所配置的资源上进行数据传输，不需要向网络装置请求分配资源。相较于动态调度机制，免授权配置调度机制适合较低延时业务。
目前，免授权配置调度机制下，网络装置为终端装置配置的资源都是周期性的。但是SPS机制可以支持周期性业务和非周期性业务，对于非周期性业务，即终端装置不定时发数据，在终端装置不发数据时，终端装置不会使用网络装置为终端装置分配的资源，从而导致资源的浪费。
发明内容
本申请提供一种资源配置方法及通信装置，用以在免授权配置调度机制下支持非周期性业务时，可以节约***资源。
第一方面，本发明实施例提供一种资源配置方法。该方法可以应用于网络装置，或者应用于具有网络功能的芯片等装置，包括：确定第一消息，所述第一消息携带配置信息和第一指示信息，所述配置信息用于指示为第一终端装置所配置的第一资源，所述第一指示信息用于指示所述第一资源是否还被配置给至少一个第二终端装置；向所述第一终端装置发送所述第一消息。
在该方案中，网络装置通过第一消息来指示为第一终端装置配置的第一资源是否还被配置给了至少一个第二终端装置，从而第一终端装置确定在至少一个第二终端装置没有在第一资源上发送数据时，可以在第一资源上发送数据，以尽量提高第一资源的利用率。
在一种可能的设计中，所述第一指示信息可以用于指示所述至少一个第二终端装置在所述第一资源发送数据的时域位置。具体地，所述第一指示信息可以用于指示所述第一终端装置和/或所述至少一个第二终端装置分别占用所述第一资源发送数据的时域起始位置 与第一资源的时域起始位置的偏移量。
在一种可能的设计中，所述第一指示信息用于指示为第一终端装置和至少一个第二终端装置配置的冗余版本(Redundancy Version，RV)。
上述描述中，第一指示信息的指示方式可以有多种，这里只是列举了几种，具体的不做限制。
在一种可能的设计中，所述配置信息还用于指示所述第一终端装置和各个第二终端装置在第一资源发送数据的重复次数相同或者不同。
在该方案中，第一终端设备和至少一个第二终端装置可以基于配置信息所配置的重复次数占用第一资源重复进行数据的传输。网络装置为了节约资源时，针对第一终端装置和至少一个第二终端装置可以配置包含不同重复次数的配置信息，从而保证第一终端装置和至少一个第二终端装置所占资源在最大重复次数之内。网络装置可以为第一终端装置和至少一个第二终端装置配置包含相同重复次数的配置信息，例如，最大重复次数相同的配置信息，这样第一终端装置和至少一个第二终端装置可以按照最大重复次数分别占用所述第一资源传输数据，以尽量提高数据传输的可靠性。
在一种可能的设计中，所述方法还包括：向所述第一终端装置发送第二指示信息，所述第二指示信息用于指示所述第一终端装置与所述至少一个第二终端复用所述第一资源的方式，其中，所述第二指示信息具体可以用于指示：所述第一终端装置与所述至少一个第二终端装置按照调度周期轮流使用所述第一资源；或，所述第一终端装置与所述至少一个第二终端装置在任意一个调度周期内交替使用所述第一资源。
在该方案中，网络装置可以通过第二指示信息通知第一终端装置与至少一个第二终端装置复用第一资源的复用方式，这样第一终端装置就不需要在第一资源上盲检至少一个第二终端装置是否占用第一资源在发送数据，尽量减轻第一终端装置用于检测资源是否可用所带来的检测负担。同时，还可以保证第一终端装置和至少一个第二终端装置占用第一资源发送数据时不会发生冲突。
在一种可能的设计中，所述第一终端装置还可以基于所述第一资源向所述至少一个第二终端装置中的一个或多个第二终端装置发送数据。
在该方案中，如果第一终端装置基于第一资源向一个第二终端装置或者多个第二终端装置发送数据，即第一终端装置和第二终端装置进行的是单播业务或者组播业务，那么第一终端装置和第二终端装置本来就是要在对方不发送数据检测对方的辅链路控制消息(Sidelink Control Information，SCI)，因此第一终端装置和第二终端装置无需额外检测彼此是否当时正在占用第一资源发送数据，从而可以减轻第一终端装置或第二终端装置用于检测资源是否可用所带来的检测负担。
在一种可能的设计中，所述方法还包括：接收来自所述第一终端装置的第二消息，所述第二消息用于指示所述至少一个第二终端装置使用所述第一资源中的部分或全部资源。在该方案中，例如第一终端装置可以将网络装置配置的第一资源再配置给至少一个第二终端装置，以尽量节约资源。
在一种可能的设计中，所述第一指示信息还可以用于指示所述第一终端装置是否需要检测所述至少一个第二终端装置的SCI。在该方案中，第一指示信息还可以用于指示第一终端装置是否需要检测至少一个第二终端装置的SCI，网络装置无需通过另一指示信息通知第一终端装置是否需要检测至少一个第二终端装置的SCI，从而可以减少信令的开销。 同时，第一终端装置可以根据第一指示信息确定是否需要检测至少一个第二终端装置的SCI，也就是检测至少一个第二终端装置是否在第一资源上发送数据，以避免与至少一个第二终端装置占用第一资源发送数据时产生冲突，提高数据传输的可靠性。
在一种可能的设计中，所述第一指示信息还用于指示所述第一终端装置检测所述至少一个第二终端装置的SCI的时域位置。在该方案中，第一指示信息还可以用于指示第一终端装置检测至少一个第二终端装置的SCI的时域位置，以使得第一终端装置只需要在第一指示信息指示的时域位置检测至少一个第二终端装置的SCI，而无需在第一资源上盲检第二终端装置的SCI，从而减轻第一终端装置检测第二终端装置的SCI所带来的检测负担。
具体地，所述第一指示信息可以具体用于指示所述第一终端装置是否需要检测至少两个第二终端装置的SCI，其中，所述至少两个第二终端装置可以在不同时域占用所述第一资源，或所述至少两个第二终端装置可以在不同频域占用所述第一资源。
在该方案中，至少两个第二终端装置被配置的资源可以是相同时域资源下的多个不同的频域资源，也可以是相同频域资源下的多个不同的时域资源，为了让第一终端装置有更多的资源可用，网络装置可以把至少两个第二终端装置的资源配置给第一终端装置。这种情况下，网络装置可以通过第一指示信息指示第一终端装置检测至少两个终端设的SCI，以保证第一终端装置在第一资源上发送数据时不会跟全部的第二终端装置占用第一资源产生冲突。
第二方面，提供第二种资源配置方法，该方法包括：
第一终端装置接收来自网络装置的第一消息，所述第一消息携带配置信息和第一指示信息，所述配置信息用于指示为所述第一终端装置所配置的第一资源，所述第一指示信息用于指示所述第一资源是否还被配置给至少一个第二终端装置；
所述第一终端装置根据所述第一消息在所述第一资源上向所述网络装置发送数据。
该方法可由第二通信装置执行，第二通信装置可以是第一终端装置或能够支持第一终端装置实现该方法所需的功能的通信装置，当然还可以是其他通信装置，例如芯片***。这里以第二通信装置是第一终端装置为例。

具体实施方式
为了使本申请实施例的目的、技术方案和优点更加清楚，下面将结合附图对本申请实施例作进一步地详细描述。
以下，对本申请实施例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)终端装置，包括向用户提供语音和/或数据连通性的设备，例如可以包括具有无线连接功能的手持式设备、或连接到无线调制解调器的处理设备。该终端装置可以经无线接入网(radio access network，RAN)与核心网进行通信，与RAN交换语音和/或数据。该终端装置可以包括用户设备(user equipment，UE)、无线终端设备、移动终端设备、设备到设备通信(device-to-device，D2D)终端设备、V2X终端设备、机器到机器/机器类通信(machine-to-machine/machine-type communications，M2M/MTC)终端设备、物联网(internet of things，IoT)终端设备、订户单元(subscriber unit)、订户站(subscriber station)，移动站(mobile station)、远程站(remote station)、接入点(access point，AP)、远程终端(remote terminal)、接入终端(access terminal)、用户终端(user terminal)、用户代理(user agent)、或用户装备(user device)等。例如，可以包括移动电话(或称为“蜂窝”电话)，具有移动终端设备的计算机，便携式、袖珍式、手持式、计算机内置的移动装置等。例如，个人通信业务(personal communication service，PCS)电话、无绳电话、会话发起协议(session initiation protocol，SIP)话机、无线本地环路(wireless local loop，WLL)站、个人数字助理(personal digital assistant，PDA)、等设备。还包括受限设备，例如功耗较低的设备，或存储能力有限的设备，或计算能力有限的设备等。例如包括条码、射频识别(radio frequency identification，RFID)、传感器、全球定位***(global positioning system，GPS)、激光扫描器等信息传感设备。
终端装置也可以称为终端设备、终端Terminal、用户设备(user equipment，UE)、移动台(mobile station，MS)、移动终端(mobile terminal，MT)等。终端设备可以是手机(mobile phone)、平板电脑(Pad)、带无线收发功能的电脑、虚拟现实(virtual reality，VR)终端装置、增强现实(augmented reality，AR)终端装置、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)中的无线终端等等。
作为示例而非限定，在本申请实施例中，该终端装置还可以是可穿戴设备。可穿戴设 备也可以称为穿戴式智能设备或智能穿戴式设备等，是应用穿戴式技术对日常穿戴进行智能化设计、开发出可以穿戴的设备的总称，如眼镜、手套、手表、服饰及鞋等。可穿戴设备即直接穿在身上，或是整合到用户的衣服或配件的一种便携式设备。可穿戴设备不仅仅是一种硬件设备，更是通过软件支持以及数据交互、云端交互来实现强大的功能。广义穿戴式智能设备包括功能全、尺寸大、可不依赖智能手机实现完整或者部分的功能，例如：智能手表或智能眼镜等，以及只专注于某一类应用功能，需要和其它设备如智能手机配合使用，如各类进行体征监测的智能手环、智能头盔、智能首饰等。
而如上介绍的各种终端装置，如果位于车辆上(例如放置在车辆内或安装在车辆内)，都可以认为是车载终端设备，车载终端设备例如也称为车载单元(on-board unit，OBU)。
2)网络装置，例如包括接入网(access network，AN)设备，例如基站(例如，接入点、宏基站、微基站或中继站等)，可以是指接入网中在空口通过一个或多个小区与无线终端设备通信的设备，或者例如，一种V2X技术中的网络装置为路侧单元(road side unit，RSU)。基站可用于将收到的空中帧与网际协议(IP)分组进行相互转换，作为终端装置与接入网的其余部分之间的路由器，其中接入网的其余部分可包括IP网络。RSU可以是支持V2X应用的固定基础设施实体，可以与支持V2X应用的其他实体交换消息。网络设备还可协调对空口的属性管理。例如，网络装置可以包括LTE***或高级长期演进(long term evolution-advanced，LTE-A)中的演进型基站(NodeB或eNB或e-NodeB，evolutional Node B)，或者也可以包括5G NR***中的下一代节点B(next generation node B，gNB)或者也可以包括云接入网(cloud radio access network，Cloud RAN)***中的集中式单元(centralized unit，CU)和分布式单元(distributed unit，DU)，本申请实施例并不限定。
3)V2X，在版本(Rel)-14/15/16版本中，V2X作为设备到设备(device-to-device，D2D)技术的一个主要应用顺利立项。V2X将在已有的D2D技术的基础上对V2X的具体应用需求进行优化，需要进一步减少V2X设备的接入时延，解决资源冲突问题。
V2X具体又包括车与车(vehicle-to-vehicle，V2V)、车与路侧基础设施(vehicle-to-infrastructure，V2I)、车与行人(vehicle-to-pedestrian，V2P)的直接通信，以及车与网络(vehicle-to-network，V2N)的通信交互等几种应用需求。如图1所示，V2V指的是车辆间的通信；V2P指的是车辆与人(包括行人、骑自行车的人、司机、或乘客)的通信；V2I指的是车辆与网络设备的通信，网络设备例如RSU，另外还有一种V2N可以包括在V2I中，V2N指的是车辆与基站/网络的通信。
其中，RSU包括两种类型：终端类型的RSU，由于布在路边，该终端类型的RSU处于非移动状态，不需要考虑移动性；基站类型的RSU，可以给与之通信的车辆提供定时同步及资源调度。
4)物理共享上行信道(PUSCH Physical Uplink Shared Channel，PUSCH)的传输，在NR***中，PUSCH的传输包括两种：
一、基于动态调度机制进行传输
在NR***中，定义了动态调度机制，即终端装置每次有数据传输时，请求网络装置分配资源，网络装置根据终端装置的请求，向终端装置发送下行控制信息(downlink control information，DCI)，DCI中含有上行数据调度信息，告诉终端装置在什么时频资源位置，以什么样的配置参数(配置参数例如包括调制与编码策略(modulation and coding scheme，MCS)或冗余版本(redundancy version，RV)等发送上行数据。
二、基于免授权配置调度机制进行传输
免授权配置调度机制下，定义了配置免授权(configured grant，CG)的概念。目前，定义了两种配置免授权类型，分别为免授权类型1(configured grant Type 1)和免授权类型2(configured grant Type 2)。其中，免授权类型1的时频资源位置由网络装置通过无线资源控制(radio resource control，RRC)信令提供给终端装置，即网络装置通过RRC信令为终端装置配置高层参数，例如免授权配置调度资源周期、免授权配置调度时频资源位置、使用免授权配置调度资源的进程数目等。终端装置接收到配置的上行链路许可(rrc-Configured Uplink Grant)的高层参数后，可以在网络装置周期配置的资源上发送数据。
免授权类型2是网络装置先发送不包含rrc-Configured Uplink Grant的高层参数，再由物理层或层1(L1)信令(即DCI)激活或去激活免授权类型2。即网络装置除了发送高层参数，还发送DCI激活或去激活CG类型2。当网络装置通过DCI激活免授权类型2时，在DCI中同时为终端装置指定SPS资源，该资源将按照配置的免授权配置调度资源周期，周期性地出现，无需再通过DCI指示其资源位置。终端装置先接收不包含rrc-ConfiguredUplinkGrant的高层参数，当接收到DCI，就可以在网络装置周期配置的时频资源上发送数据。
5)冗余版本(Redundancy Version，RV)：免授权Configured grant的配置包括：发送周期、重复次数、发送起始时间、RV等。目前5G协议定义的RV有3种，分别为(0，0，0，0)，(0，3，0，3)，(0，2，3，1)。RV定义了终端装置发送数据的发送时机，终端装置只有在RV为0的时刻才可以开始发送数据。例如，请参见图2，为终端装置的两种RV的示意图，其中一种RV，例如RV1为(0，3，0，3)，网络装置配置终端装置发送数据的重复次数为8，则终端装置只能在第1次，第3次，第5次和第7次发送机会可以开始发送数据。又例如，另一种RV，例如RV2为(0，2，3，1)，网络装置配置终端装置发送数据的重复次数为8，则终端装置只能在第1次和第5次发送机会才可以开始发送数据。需要说明的是，这里的重复次数指示的是终端装置在一个发送周期内发送数据的最大重复次数。图2中，以一个发送周期(Periodicity)包括8个发送机会为例。
6)第五代移动(the fifth generation，5G)通信***的应用场景，国际电信联盟(international telecommunication union，ITU)为5G以及未来的移动通信***定义了三大类应用场景，这三大类应用场景分别是增强型移动宽带(enhanced mobile broadband，eMBB)、高可靠低时延通信(ultra reliable and low latency communications，URLLC)以及海量机器类通信(massive machine type communications，mMTC)。其中，典型的eMBB业务有：超高清视频、增强现实(augmented reality，AR)、虚拟现实(virtual reality，VR)等，这些业务的主要特点是传输数据量大、传输速率很高。典型的URLLC业务有：工业制造或生产流程中的无线控制、无人驾驶汽车和无人驾驶飞机的运动控制以及远程修理、远程手术等触觉交互类应用，这些业务的主要特点是要求超高可靠性、低延时，传输数据量较少以及具有突发性。典型的mMTC业务有：智能电网配电自动化、智慧城市等，主要特点是联网设备数量巨大、传输数据量较小、数据对传输时延不敏感，这些mMTC终端需要满足低成本和非常长的待机时间的需求。不同业务对移动通信***的需求不同，如何更好地同时支持多种不同业务的数据传输需求，是当前5G通信***所需要解决的技术问题。例如，如何同时支持URLLC业务和eMBB业务就是当前5G移动通信***的讨论热点之一。
7)本申请实施例中的术语“***”和“网络”可被互换使用。“至少一个”是指一个或者多个，“多个”是指两个或两个以上。“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的情况，其中A,B可以是单数或者复数。字符“/”一般表示前后关联对象是一种“或”的关系。“以下至少一项(个)”或其类似表达，是指的这些项中的任意组合，包括单项(个)或复数项(个)的任意组合。例如，a,b,或c中的至少一项(个)，可以表示：a,b,c,a-b,a-c,b-c,或a-b-c，其中a,b,c可以是单个，也可以是多个。
以及，除非有相反的说明，本申请实施例提及“第一”、“第二”等序数词是用于对多个对象进行区分，不用于限定多个对象的顺序、时序、优先级或者重要程度。例如，第一同步信号和第二同步信号，只是为了区分不同的同步信号，而并不是表示这两个同步信号的内容、优先级、发送顺序或者重要程度等的不同。
如上介绍了本申请实施例涉及的一些概念，下面介绍本申请实施例的技术特征。
在NR***中，PUSCH的传输可以基于免授权配置调度机制，免授权配置调度机制支持周期性业务和非周期性业务。但是在免授权配置调度机制下，网络装置为终端装置配置的资源是周期性的，那么就可能出现网络装置为终端装置配置了资源，但是当前终端装置并不需要发送或接收数据，这就导致了资源的浪费。
鉴于此，提供本申请实施例的技术方案。在本申请实施例中，多个终端装置可以复用同一资源，例如，第一资源，这样当多个终端装置中的某个终端装置在第一资源上不进行数据传输时，多个终端装置中的其他终端装置可以利用第一资源进行数据传输，从而节约了资源。网络装置为所述某个终端装置配置第一资源时，可以向所述某个终端装置发送指示信息，该指示信息可以用于指示第一资源还有没有被配置给其他终端装置，从而某个终端装置可以根据指示信息，在第一资源上发送数据，以避免与其他终端装置利用第一资源发送数据时可能造成的冲突。
本申请实施例提供的技术方案可以应用于5G***中，例如NR***，或者应用于LTE***中，或者还可以应用于下一代移动通信***或其他类似的通信***，具体的不做限制。
下面介绍本申请实施例所应用的一种网络架构，请参考图3。
图3中包括核心网设备、网络装置和至少一个终端装置，图3以至少一个终端装置是两个终端装置为例。终端设备通过无线的方式与网络装置相连，网络装置通过无线或有线方式与核心网设备连接。核心网设备与网络装置可以是独立的不同的物理设备，也可以是将核心网设备的功能与网络装置的逻辑功能集成在同一个物理设备上，还可以是一个物理设备上集成了部分核心网设备的功能和部分的网络装置的功能。终端装置可以是固定位置的，也可以是可移动的。图3只是示意图，该通信***中还可以包括其它网络装置，如还可以包括无线中继设备和无线回传设备，在图3中未画出。本申请的实施例对该移动通信***中包括的核心网设备、网络装置和终端装置的数量不做限定。
网络装置是终端装置通过无线方式接入到该移动通信***中的接入设备，可以是基站NodeB、演进型基站eNodeB、5G通信***中的基站、未来移动通信***中的基站或无线保真(WIreless-FIdelity，Wi-Fi)***中的接入节点等，本申请的实施例对无线网络装置所采用的具体技术和具体设备形态不做限定。
网络装置和终端装置可以部署在陆地上，包括室内或室外、手持或车载；也可以部署在水面上；还可以部署在空中的飞机、气球和卫星上。本申请的实施例对网络装置和终端 装置的应用场景不做限定。
本申请的实施例可以适用于下行信号传输，也可以适用于上行信号传输，还可以适用于D2D的信号传输。对于下行信号传输，发送设备是网络装置，对应的接收设备是终端装置。对于上行信号传输，发送设备是终端装置，对应的接收设备是网络装置。对于D2D的信号传输，发送设备是终端装置，对应的接收设备也是终端装置。本申请的实施例对信号的传输方向不做限定。
网络装置和终端装置之间以及终端装置和终端装置之间可以通过授权频谱(licensed spectrum)进行通信，也可以通过免授权频谱(unlicensed spectrum)进行通信，也可以同时通过授权频谱和免授权频谱进行通信。网络装置和终端装置之间以及终端装置和终端装置之间可以通过6G以下的频谱进行通信，也可以通过6G以上的频谱进行通信，还可以同时使用6G以下的频谱和6G以上的频谱进行通信。本申请的实施例对网络装置和终端装置之间所使用的频谱资源不做限定。
下面结合附图介绍本申请实施例提供的技术方案。
本申请实施例提供第一种资源配置方法，请参见图4，为该方法的流程图。在下文的介绍过程中，以该方法应用于图1或图3所示的网络架构为例。另外，该方法可由两个通信装置执行，这两个通信装置例如为第一通信装置和第二通信装置。其中，第一通信装置可以是网络装置或能够支持网络装置实现该方法所需的功能的通信装置，或者第一通信装置可以是终端装置或能够支持终端装置实现该方法所需的功能的通信装置，当然还可以是其他通信装置，例如芯片***。对于第二通信装置也是同样，第二通信装置可以是网络装置或能够支持网络装置实现该方法所需的功能的通信装置，或者第二通信装置可以是终端装置或能够支持终端装置实现该方法所需的功能的通信装置，当然还可以是其他通信装置，例如芯片***。且对于第一通信装置和第二通信装置的实现方式均不做限制，例如第一通信装置可以是网络装置，第二通信装置是终端装置，或者第一通信装置和第二通信装置都是终端装置，或者第一通信装置是网络装置，第二通信装置是能够支持终端装置实现该方法所需的功能的通信装置，等等。其中，网络装置例如为基站。
为了便于介绍，在下文中，以该方法由网络装置和终端装置执行为例，也就是，以第一通信装置是网络装置、第二通信装置是终端装置为例。因为本实施例是以应用在图1或图3所示的网络架构为例，因此，下文中所述的网络装置可以是图3所示的网络架构中的网络装置，下文中所述的终端装置可以是图1或图3所示的网络架构中的终端装置。如果下文中第一终端装置是图1所示的网络架构中的车辆1，那么下文中第二终端装置可以是图1所示的网络架构中的车辆2。或者，如果下文中第一终端装置是图3所示的网络架构中的终端装置1，那么下文中第二终端装置可以是图3所示的网络架构中的终端装置2。
S41、网络装置确定第一消息，第一消息携带配置信息和第一指示信息，配置信息用于指示为第一终端装置所配置的第一资源，第一指示信息用于指示第一资源是否还被配置给至少一个第二终端装置。
网络装置要为一个终端装置，例如第一终端装置配置资源，就可以通过第一消息来进行配置。在本申请实施例中，“确定”第一消息，也可以理解为“生成”第一消息或“得到”第一消息等，对于网络装置确定第一消息的方式不做限制。第一消息可以是专用信令，例如为无线资源控制(Radio Resource Control，RRC)信令，或者下行控制信息(Downlink Control Information，DCI)信令等。作为一种实施方式，第一消息可以携带配置信息，该配置信 息可以用于指示为第一终端装置所要配置的第一资源。为了节约资源，网络装置也可以将第一资源配置为至少一个第二终端装置。如果第一终端装置和至少一个第二终端装置均在第一资源上传输数据，可能会出现第一终端装置和其中的一个第二终端装置或者多个第二终端装置同时在第一资源上传输数据，那么第一终端装置和至少一个第二终端装置就会彼此造成干扰，影响接收端正常接收数据。甚至，由于第一终端装置和至少一个第二终端装置彼此造成干扰，导致第一终端装置或至少一个第二终端装置传输数据失败。
为此，第一消息还可以携带第一指示信息，该第一指示信息可以用于指示第一资源是否还被配置给至少一个第二终端装置，这样，第一终端装置就可以根据第一指示信息知晓是否有其他终端装置与第一终端装置复用第一资源，从而第一终端装置可以根据第一指示信息确定如何在第一资源上发送数据，以避免与至少一个第二终端装置利用第一资源发送数据时可能造成的冲突。
或者，作为另一种实施方式，配置信息和第一指示信息放在不同的消息中发送，例如，配置信息携带在第一消息中，第一指示信息携带在第二消息中，网络装置可以向第一终端装置发送第一消息和第二消息。同理，第二消息也可以是RRC信令或者DCI信令。其中，网络装置可以先发送第一消息后发送第二消息，或者可以先发送第二消息后发送第一消息，或者可以同时发送第一消息和第二消息。
在本申请实施例中，第一指示信息用于指示第一资源是否还被配置给至少一个第二终端装置，包括但不限于如下几种方式中的一种：
1、第一指示信息占用一个比特，这个比特的取值用于指示第一资源是否还被配置给至少一个第二终端装置。例如，比特的取值为0，则可以指示第一资源没有被配置给至少一个第二终端装置；相对地，比特的取值为1，则可以指示第一资源还被配置给至少一个第二终端装置。或者，比特的取值为1，则可以指示第一资源没有被配置给至少一个第二终端装置；相对地，比特的取值为0，则可以指示第一资源还被配置给至少一个第二终端装置。第一指示信息占用一个比特，以尽量节省第一指示信息占用的比特数。
2、第一指示信息用于指示至少一个第二终端装置在第一资源发送数据的时域位置，这种方式通过隐式方式指示第一资源是否还被配置给至少一个第二终端装置。既然至少一个第二终端装置可以在第一资源上的某些时域位置发送数据，那么隐含指示了第一资源被配置给了至少一个第二终端装置。
例如，配置信息还可以用于指示为第一终端装置配置的RV，第一指示信息可以占用至少两个比特，例如可以是与RV对应的bitmap。请参见图5，为终端装置在第一资源发送数据的一种时域位置示意图。网络装置为第一终端装置(图5中所示的UE1)配置的RV为(0，3，0，3)，第一指示信息是00，用于指示没有第二终端装置可以占用第一资源，也就是第一资源没有被配置给一个第二终端装置；或者，第一指示信息可以是01，用于指示第二终端装置(图5中所示的UE2)占用第一资源的起始时域位置为第2个发送机会，也就是在第2个发送机会有第二终端装置可以占用第一资源。又例如，请参见图6，为终端装置在第一资源发送数据的一种时域位置示意图。网络装置为第一终端装置(图6中所示的UE1)配置的RV为(0，2，3，1)，第一指示信息可以是0010，用于指示在第3个发送机会有第二终端装置(图6中所示的UE3)可以占用第一资源；或者，第一指示信息可以是0000，用于指示没有第二终端装置可以占用第一资源；或者，第一指示信息可以是0110，用于指示在第2个发送机会和第3个发送机会分别有第二终端装置可以占用第一资源，这 两个第二终端装置可以是图6中的UE2和UE3。当然，通过bitmap来指示只是一种示例，本申请实施例不限制具体如何通过第一指示信息来指示第一资源是否还被配置给至少一个第二终端装置。
在具体实施时，第一指示信息指示第一终端装置和至少一个第二终端装置在第一资源发送数据的时域位置，包括但不限于如下几种方式中的一种：
1)第一指示信息可以用于指示第一终端装置在第一资源发送数据的时域起始位置与第一资源的时域起始位置的偏移量。这种情况下，网络装置和第一终端装置可以事先约定，可以默认至少一个第二终端装置中的各个第二终端装置在第一资源发送数据的时域起始位置与第一资源的时域起始位置的偏移量为0。
2)第一指示信息可以用于指示至少一个第二终端装置中的各个第二终端装置在第一资源发送数据的时域起始位置与第一资源的时域起始位置的偏移量。这种情况下，网络装置和第一终端装置可以事先约定，可以默认第一终端装置在第一资源发送数据的时域起始位置与第一资源的时域起始位置的偏移量为0。
3)第一指示信息可以用于指示第一终端装置在第一资源发送数据的时域起始位置与第一资源的时域起始位置的偏移量，以及至少一个第二终端装置中的各个第二终端装置在第一资源发送数据的时域起始位置与第一资源的时域起始位置的偏移量。
如上的1)-3)方式中，第一终端装置在第一资源发送数据的时域起始位置，以及第二终端装置在第一资源发送数据的时域起始位置可以采用RV指示。
具体地，请继续参见图5，为终端装置在第一资源发送数据的时间位置示意图。网络装置为第一终端装置(图5中的UE1)和第二终端装置(图5中的UE2)配置的RV均为(0，3，0，3)。第一指示信息可以用于指示UE1在第一资源发送数据的时域起始位置与第一资源的时域起始位置的偏移量，和/或UE2在第一资源发送数据的时域起始位置与第一资源的时域起始位置的偏移量。例如，第一指示信息可以指示UE1在第一资源发送数据的时域起始位置与第一资源的时域起始位置的偏移量为0，并指示UE2在第一资源发送数据的时域起始位置与第一资源的时域起始位置的偏移量为1，那么对应图5，UE1可以从第1个发送机会开始发送数据，而UE2本来根据RV可以从第1个发送机会开始发送数据，但是由于第一指示信息指示UE2在第一资源发送数据的时域起始位置与第一资源的时域起始位置的偏移量为1，所以UE2是在第2个发送机会开始发送数据。如果网络装置为UE1和UE2配置的重复次数均为8，那么UE1在第一资源发送数据的时域起始位置分别为奇数次发送机会(1，3，5，7)，UE2在第一资源发送数据的时域起始位置分别为偶数次发送机会(2，4，6，8)。
需要指出的是，网络装置还可以为第一终端装置和至少一个第二终端装置在第一资源中配置不同的时域起始发送位置，以避免第一终端装置和至少一个第二终端装置同时发送数据造成干扰。例如，网络装置为第一终端装置和至少一个第二终端装置配置不同的RV来对应不同的时域起始发送位置。这种情况下，网络装置可以不通知第一终端装置和至少一个第二终端装置各自的时域起始发送位置。
4)第一指示信息还可以通过指示为第一终端装置和第二终端装置配置的RV来实现指示第一终端装置在第一资源上发送数据的时域位置，和/或，至少一个第二终端装置在第一资源发送数据的时域位置。
在一种可能的实施方式中，第一指示信息可以携带第一终端装置配置的RV信息，和/ 或，为第二终端装置配置的RV信息。例如，第一指示信息携带RV信息指示第一终端装置的RV为(0，3，0，3)，以及第二终端装置指示的RV为(3，0，3，0)。那么根据第一指示信息中的RV信息可以确定第一终端装置在第一资源发送数据的时域起始位置分别为奇数次发送机会(1，3，5，7)，而第二终端装置在第一资源发送数据的时域起始位置分别为偶数次发送机会(2，4，6，8)。由于目前5G协议中没有定义(3，0，3，0)的RV，这种情况下，网络装置和终端装置可以事先约定新增加RV的可选项，例如，(3，0，3，0)，网络装置可以通过信令为终端装置配置RV，该信令可以携带用于指示(3，0，3，0)的RV信息。
需要说明的是，上述实施例以RV指示第一指示信息中的第一终端装置在第一资源上发送数据的时域起始位置，和/或，至少一个第二终端装置在第一资源发送数据的时域起始位置仅是举例。本申请实施例也可以通过其他方式指示该信息，例如，第一资源在时域上包括8个时间单元，可以用8比特bit分别指示8个时间单元(发送机会)，每个1bit指示对应的时间单元是否还被配置给第二终端装置，再用2bit指示第一终端装置在第一资源上发送数据的时域起始位置，和/或，至少一个第二终端装置在第一资源发送数据的时域起始位置。
在本申请实施例中，第一指示信息可以指示第一终端装置和/或第二终端装置在第一资源发送数据的时域位置，从而第一终端装置可以根据第一指示信息确定如何在第一资源上发送数据，以尽量避免第一终端设备和第二终端装置占用相同的资源，同时发送数据所导致数据发送失败，提高数据传输的可靠性。
S42、网络装置向第一终端装置发送第一消息，则第一终端装置接收来自网络装置的第一消息。
网络装置确定第一消息后，如果第一消息是专用信令，则网络装置向第一终端装置发送第一消息，这里的“发送”，可以理解为单播，终端装置就可以接收来自网络装置的第一消息。
S43、第一终端装置根据接收的第一消息在第一资源上向网络装置发送数据。
如果第一消息包括配置信息和第一指示信息，那么第一终端装置接收第一消息后，根据第一消息携带的配置信息可以确定网络装置为第一终端装置配置的第一资源。第一终端装置还可以根据第一消息携带的第一指示信息确定第一终端装置是否被配置给至少一个第二终端装置，从而根据第一指示信息在第一资源上向网络装置发送数据，以避免与至少一个第二终端装置在第一资源上发生冲突，提高传输数据的可靠性。
具体地，第一终端装置可以根据第一指示信息确定在每个调度周期内发送数据的时域位置，以及发送数据之前是否要检测至少一个第二终端装置中的各个第二终端装置的SCI。其中，如果第一终端装置检测到某个第二终端装置的SCI，则可以认为某个第二终端装置在第一资源上发送数据。第一终端装置根据在每个调度周期内发送数据的时域位置，以及所检测的各个第二终端装置的SCI，可以确定发送数据的起始时域位置，以避开与某个第二终端装置发送数据可能发送的冲突，例如，第一终端装置和某个第二终端装置同时在相同的时域位置发送数据。
根据第一指示消息的可能实现方式的不同，第一终端装置根据第一指示信息确定在每个调度周期内发送数据的时域位置，以及发送数据之前是否要检测各个第二终端装置的SCI方式也有所不同，包括但不限于以下几种方式的一种：
1、如果第一指示信息占用1个比特，用于指示第一资源是否还被配置给至少一个第二终端装置，那么第一终端装置根据第一指示信息确定在每次发送数据之前均需要检测在发 送数据的起始时域位置的前面发送机会的SCI。这是因为，第一指示信息仅指示第一资源是否被复用，并没有指示第一资源在哪些时域位置被复用，从而第一终端装置每次发送数据之前都需要检测SCI，以尽量保证避免与至少一个第二终端装置在第一资源上发生冲突。如果第一终端装置根据检测的SCI确定第一终端装置在第一资源上发送数据的本次发送机会上存在第二终端装置发送数据的情况，那么第一终端装置暂时先不发送数据，而是在确定本次发送机会没有第二终端装置发送数据的情况时，再在本次发送机会进行发送数据。
当然，如果第一指示信息指示第一资源没有被配置给至少一个第二终端装置，则第一终端装置就不需要检测任何第二终端装置的SCI。可再参考图8，通过图8可以看到图4的实施例的大致过程。从图8中可以看到，网络装置可以向第一终端装置(UE1)以及第二终端装置(UE2)分别发送配置信息和第一指示信息。UE1和UE2可以根据第一指示信息确定是否检测彼此的SCI，当第一资源没有同时被配置给UE1和UE2时，则不需要检测彼此的SCI，所以图8中用虚线示意SCI。
2、如果第一指示信息占用至少两个比特，用于指示至少一个第二终端装置在第一资源发送数据的时域位置。则第一终端装置可以根据第一指示信息确定在第一资源的什么位置检测SCI，不需要盲检，也就是可能不需要在每次发送数据之前都检测在发送数据的起始时域位置的前面发送机会的SCI，尽量减轻第一终端装置的负担。
具体地，第一终端装置通过网络装置的配置，例如配置信息和第一指示信息，确定第一终端装置在第一资源上发送数据的起始发送时域位置的偏移量、一个调度周期内的重复次数、发送周期、周期编号，以确定在本次调度周期内发送数据的发送时域位置和最大发送次数，以及至少一个第二终端装置在第一资源发送数据的起始发送时域位置，从而第一终端装置进一步确定是否需要在本次调度周期内发送数据的发送时域位置之前检测第二终端装置的SCI。如果需要检测第二终端装置的SCI，且检测到了第二终端装置的SCI，则进一步根据所检测到的SCI确定第一资源上的哪些资源可用，在确定可用资源上发送数据。
这里，第一终端装置在第一资源上发送数据的起始发送时域位置的偏移量为第一终端装置在第一资源上发送数据的第一次发送机会与第一消息中配置信息指示的时域位置偏移量(第一资源的时域起始位置的偏移量)，例如，相对于配置信息指示的时间位置的发送机会偏移个数。周期编号可以是从首次发送机会所在周期为0开始编号、下一个首次发送机会所在周期为1。发送周期可以是相邻周期间隔。
第一终端装置检测至少一个第二终端装置的SCI之后，可以根据所检测到的SCI确定第一资源上的哪些资源可用。下面以第一终端装置为例，介绍如何根据所检测到的SCI确定第一资源上的哪些资源可用。需要说明的是，第二终端装置根据所检测到的SCI确定第一资源上的哪些资源可用的过程和第一终端装置根据所检测到的SCI确定第一资源上的哪些资源可用的过程相同。
在介绍如何根据所检测到的SCI确定第一资源上的哪些资源可用之前，先介绍如何确定每个周期内的最大发送次数和发送数据的起始发送机会。
假设网络装置是通过RV配置来通知终端装置的，例如，网络装置为第一终端装置配置的RV为(0，2，3，1)，且第一资源还被配置为3个第二终端装置，也就是第一资源的复用用户个数为3。例如，请参见图7，图7为多个终端装置在第一资源发送数据的时域位置图。图7以包括3个终端装置为例，这3个终端装置分别为UE1、UE2和UE3，网络装置为UE1、UE2和UE3配置的RV均为(0，2，3，1)，且网络装置为UE1、UE2和UE3配置的在第一资 源发送数据的最大重复次数均相同，例如，最大重复次数为8。在第一个周期内(图7中从左开始的第一个周期)，UE1有机会可以第一个开始发送数据，然而到了第二个周期，UE3有机会可以开始第一个开始发送数据，这样可以尽量均衡多个终端装置进行业务传输的时延。在图7中，第一终端装置在第1个周期内以第1个发送机会和第5个发送机会为起始发送机会，最大重复次数为8；第一终端装置在第2个周期内以第2个发送机会和第6个发送机会为起始发送机会，最大重复次数为7；第一终端装置在第3个周期内以第3个发送机会和第7个发送机会为起始发送机会，最大重复次数为6；第一终端装置在第4个周期内以重新第1个发送机会和第5个发送机会为起始发送机会，最大重复次数为8。需要说明的是，如果终端装置重复多次发送数据时，在网络装置配置的周期内起始发送机会为1，最多发送8次，而如果起始发送机会不是第一个发送机会，终端装置即使没有达到最大重复次数8次，发送到资源分配的截止位置时也需要停止发送了。例如，在第一个周期，UE1在第1个发送机会开始发送数据，最多可以重复发送8次，而UE2在第2个发送机会开始发送，最多可以重复发送7次，也就是发送到资源分配的截止位置时停止发送数据了。
另外，本申请实施例中，网络装置和终端装置可以约定在每个周期内的起始发送机会以复用用户个数为模，依次延迟1个发送机会。这是为了让多个终端装置处于公平的条件下，不能总让某个终端装置一直都可以第一个开始发送数据的。上述图7以此为例。
第一终端装置根据所检测到的SCI确定第一资源上的哪些资源可用时，可以根据所检测到的第二终端装置的SCI携带的第二终端装置本次发送数据的最大重复次数，确定第二终端装置发送数据的起始发送位置和结束发送位置。例如，第二终端装置本次发送数据的需要的重复次数为2次、发送数据的时域起始发送位置位于一个调度周期内的第一个发送机会，则其他终端装置可以根据SCI确定该终端装置需要占据第1个发送机会和第2个发送机会发送数据。
为了便于理解，请继续参见图7，以一个发送周期为例，当网络装置为UE1配置的第一指示消息指示UE1在第一资源发送数据的时域起始位置与第一资源的时域起始位置的偏移量为0，那么UE1可以确定在第1个发送机会不需要检测SCI，且UE1在第一资源上发送数据的最大重复次数为8次。当网络装置为UE2配置的第一指示消息指示UE2在第一资源发送数据的时域起始位置与第一资源的时域起始位置的偏移量为1，则UE2可以确定在第2个发送机会可以开始发送数据，那么UE2就需要在第1个发送机会检测UE1的SCI，且UE2可以确定在第一资源上发送数据的最大重复次数为7次。如果UE2在第1个发送机会检测到UE1的SCI，那么UE2先不在第2个发送机会发送数据，UE2可以依次检测第2个发送机会以及第2个发送机会之后的发送机会是否存在UE1的SCI，直到UE2没有检测到UE1的SCI，则UE2在下一个配置的初始发送机会发送数据。另外，如果第一终端装置的SCI中指示了本次发送的重复次数，则第二终端装置可以根据该SCI判断第一资源中哪些剩余的资源可用，而不需要在所有的发送机会都检测第一终端装置的SCI。
如上的实施例中，网络装置为第一终端装置和至少一个第二终端装置所配置的最大重复次数不相同，也就是第一终端装置和至少一个第二终端装置在第一资源发送数据的最大重复次数不相同。这种情况下，第一终端装置和至少一个第二终端装置所占用的资源均在最大重复次数之内。例如，请继续参见图7，一个发送周期内时域资源最多占用8个发送机会，不同终端装置的最大重复次数不一样，以此保证占用的时间资源不会超过8个发送机会(时间单元)，节约了资源。
作为另一种实施方式，配置信息还可以用于指示第一终端装置和至少一个第二终端装置中的各个第二终端装置在第一资源发送数据的最大重复次数相同，也就是网络装置为第一终端装置和至少一个第二终端装置配置的最大重复次数相同。在这种情况下，由于第一终端装置和至少一个第二终端装置在第一资源上发送数据的时域起始发送位置不相同，那么为了保证第一终端装置和至少一个第二终端装置相同的最大重复次数，第一终端装置和至少一个第二终端装置共占用的资源可能就较多。
为了便于理解，请参见图9，以图9为包括两个终端装置，这两个终端装置分别为UE1和UE2为例，介绍当第一终端装置和至少一个第二终端装置配置的重复次数相同，第一终端装置和至少一个第二终端装置共占用的资源较多的原理。
图9以网络装置为UE1和UE2配置的RV均为(0，3，0，3)为例，UE1可以确定将第1个发送机会、第3个发送机会、第5个发送机会或第7个发送机会作为发送数据的时域起始发送位置，且在第1个发送机会不需要检测UE2的SCI，而在第3个发送机会、第5个发送机会或第7个发送机会均需要检测前面发送时机的UE2的SCI。UE2可以确定可以将第2个发送机会、第4个发送机会、第6个发送机会或第8个发送机会作为发送数据的时域起始发送位置，且在每个起始发送位置均需要检测前面发送时机的UE1的SCI。从图9中可以看出，为了保证UE1和UE2具有相同的最大重复次数，那么在第一个周期(从图9左起的第一个)内，UE2所占用的时间单元还是8个发送机会，只不过是向时域方向扩展了一个发送机会，所以，UE1和UE2共占用的时间单元是9个发送机会，相较于图7的第一个周期，UE1和UE2所占用的时间单元(即8个发送机会)来说，图9中的UE1和UE2所占用的时间单元较多。同理，图9中位于第二周期内，UE1所占用的时间单元向时域方向扩展了一个发送机会，UE1和UE2所占用的时间单元也较多。
本申请实施例中，第一终端装置和至少一个第二终端装置复用第一资源。在一种可能的实施方式中，网络装置还可以指示第一终端装置和至少一个第二终端装置如何复用第一资源。这种情况下，第一终端装置和至少一个第二终端装置按照网络装置的指示复用第一资源，无需额外增加检测彼此的SCI的次数，从而减轻终端装置的负担。
例如，网络装置可以向第一终端装置发送第二指示信息，该第二指示信息用于指示第一终端装置与至少一个第二终端复用第一资源的方式。需要说明的是，这里的第二指示信息也可以是如上述的第一指示信息，也就是第一指示信息还用于指示第一终端装置与至少一个第二终端复用第一资源的方式，这样有助于减少信令的开销。下文中，以网络装置向第一终端装置发送第二指示信息为例。
根据第一终端装置和至少一个第二终端装置所进行的业务类型的不同，第一终端装置和至少一个第二终端装置复用第一资源的复用方式也可能有所不同。在本申请实施例中，第一终端装置和至少一个第二终端装置复用第一资源的复用方式，包括但不限于如下几种方式中的一种：
1、一种可能的应用场景为第一终端装置基于第一资源向至少一个第二终端装置中的一个第二终端装置发送数据，也就是第一终端装置和第二终端装置进行单播业务。在这种场景下，第一终端装置和第二终端装置复用第一资源的复用方式包括如下方式中的一种：
1)、第二指示信息可以用于指示第一终端装置与第二终端装置按照调度周期轮流使用第一资源。
在一种可能的实施方式中，网络装置为第一终端装置和第二终端装置配置了相同的第 一资源。第二指示信息可以占用1个比特，这个比特的取值可以指示第一终端装置使用奇数发送周期在第一资源发送数据，且指示第二终端装置使用偶数发送周期在第一资源发送数据。例如，这个比特的取值为0，则指示第一终端装置使用奇数发送周期在第一资源发送数据，且指示第二终端装置使用偶数发送周期在第一资源发送数据。当然这里仅是举例，也有可能这个比特的取值为1，则指示第一终端装置使用奇数发送周期在第一资源发送数据，且指示第二终端装置使用偶数发送周期在第一资源发送数据。这里的奇数发送周期可以理解为在第一资源上的第1个发送周期，第3个发送周期等，对应地，偶数发送周期可以理解为在第一资源上的第2个发送周期，第4个发送周期等。
在另一种可能的实施方式中，网络装置为第一终端装置配置了第一资源，但是第一终端装置将第一资源中的部分资源或全部资源配置给第二终端装置，例如，第一终端装置通过侧行链路sidelink资源将配置信息发送给第二终端装置。该配置信息可能包括第一资源中的部分资源或全部资源，或者，重复次数，发送周期等。第一终端装置为第二终端装置配置资源后，可以向网络装置发送第三消息，该第三消息用于指示第二终端装置使用第一资源中的部分或全部资源，以告知网络装置第二终端装置所使用的资源是第一终端装置的资源，这样，网络装置就可以根据第三消息发送第二指示信息，即为第一终端装置和第二终端装置指定复用第一资源的复用方式。这种情况下，第二指示信息可以用于指示第二终端装置在接收到第一终端装置发送的配置信息后的第1个周期开始，与第一终端装置按照调度周期轮流使用第一资源。
需要说明的是，在这种情况下，第三消息还可以用于指示网络装置不要将配置给第一终端装置的第一资源再配置给其他终端装置。这里的其他终端装置指的是除第二终端装置之外的终端装置。
2)、第二指示信息可以用于指示第一终端装置与第二终端装置在任意一个调度周期内交替使用第一资源。
在一种可能的实施方式中，第二指示信息可以用于指示第一终端装置和第二终端装置在第一资源的第1个发送周期内的时域偏移量，从而第一终端装置和第二终端装置可以根据第二指示信息为各自指定的时域偏移量确定在第1个发送周期的发送数据的起始发送位置，之后在确定的起始发送位置开始发送数据。这样，第一终端装置和第二终端装置不需要等到下一个发送周期开始发送数据，有利用减少发送数据的时延，有助于延时要求较低的业务传输。
或者，在另一种可能的实施方式中，网络装置可以不向第一终端装置和第二终端装置发送第二指示信息，这种情况下，网络装置和第一终端装置可以事先约定第一终端装置和第二终端装置按照预设的复用方式复用第一资源。一种可能的预设的复用方式可以是按照第一终端装置的身份标识(identification，ID)和第二终端装置的ID的大小设置发送数据的顺序。例如，ID越小，则开始发送数据的优先级越高，例如，由于第一终端装置和第二终端装置进行的是单播业务，所以第一终端装置和第二终端装置彼此知晓各自的ID，如果第一终端装置的ID小于第二终端装置的ID，则第一终端装置和第二终端装置可以确定复用第一资源的方式为第一终端装置在第1个发送周期的第1个发送机会开始发送数据，第二终端装置在第2个发送周期的第1个发送机会开始发送数据。
另外，上述两种实施方式所提供的第一终端装置和第二终端装置复用第一资源的复用方式既适用于网络装置为第一终端装置和第二终端装置配置相同的第一资源的情况，又适 用于第一终端装置将网络装置配置的第一资源中的部分资源或全部资源配置给第二终端装置的情况。
网络装置通过第二指示信息指示第一终端装置和第二终端装置复用第一资源的复用方式，或者，网络装置指示第一终端装置和第二终端装置按照约定方式复用第一资源，以尽量避免第一终端装置和第二终端装置进行单播业务时可能发生的冲突，以免造成第一终端装置和第二终端装置无法听到对方消息的问题。
2、一种可能的应用场景为第一终端装置基于第一资源向多个第二终端装置发送数据，也就是第一终端装置和多个第二终端装置进行组播业务。
这种情况下，第二指示信息可以用于指示第一终端装置与多个第二终端装置在任意一个调度周期内交替使用第一资源。在一种可能的实施方式中，第二指示信息可以用于指示第一终端装置和多个第二终端装置中的每个终端装置在第一资源的第1个发送周期内的时域偏移量，从而第一终端装置和每个第二终端装置可以根据第二指示信息为各自指定的时域偏移量确定在第1个发送周期的发送数据的起始发送位置，之后在确定的起始发送位置开始发送数据。例如，如果第一终端装置和多个第二终端装置所使用的RV均为(0，2，3，1)，则第二指示信息可以指示第一终端装置和每个第二终端装置在RV对应的不同位置发送数据。
网络装置通过第二指示信息指示第一终端装置和多个第二终端装置复用第一资源的复用方式，即第一终端装置和多个第二终端装置轮流使用第一资源，以尽量避免第一终端装置和多个第二终端装置进行组播业务时可能发生的冲突，以免造成第一终端装置和多个第二终端装置无法听到对方消息的问题。
上述第一终端装置和至少一个第二终端装置复用第一资源，可提高第一资源利用率。但是如果第一资源是网络装置通过免授权配置调度机制分配给第一终端装置和至少一个第二终端装置的，那么第一终端装置和至少一个第二终端装置可以周期性使用第一资源。但是如果第一终端装置和至少一个第二终端装置利用第一资源进行非周期业务，那么第一终端装置和至少一个第二终端装置在第一资源上不一定发送数据，此时还是可能造成资源的浪费。
为此，在本申请实施例中，网络装置可以指示通过动态调度机制配置资源的终端装置利用第一资源，以进一步提高资源的利用率。下文中以第一终端装置为通过动态调度机制配置资源的终端装置，第二终端装置为通过免授权配置调度机制配置资源的终端装置为例。网络装置通知第一终端装置使用第二终端装置的资源的通知方式，包括但不限于以下几种中的一种：
1、可再参考图10，通过图10可以看到图4的实施例的大致过程。网络装置为第二终端装置发送配置信息，用于为第二终端装置配置资源。同样地，网络装置也可以为第一终端装置发送配置信息，用于为第一终端装置配置资源。只是对应第二终端装置的配置信息所指示的资源与对应第一终端装置配置信息所指示的资源相同。
2、网络装置可以先给第二终端装置配置资源，并提前将为第二终端装置配置资源的配置信息发送给第一终端装置，以告知第一终端装置可以使用为第二终端装置配置的资源。其中，网络装置可以提前将多个第二终端装置的配置信息发送给第一终端装置，多个第二终端装置可以是通过免授权配置调度机制配置资源的终端装置中的部分终端装置或全部终端装置。
3、网络装置通过为第一终端装置发送配置信息以配置资源，另外，网络装置还可以再给第一终端装置发送一条信息，以通过这条信息通知第一终端装置，网络装置为第一终端装置配置的资源是第二终端装置的资源。例如，网络装置可以向第一终端装置发送DCI，该DCI携带指示信息，该指示信息指示为第一终端装置配置的资源是否是第二终端装置的资源。例如，该指示信息包括1个比特，当这个比特的取值为0时，表示为第一终端装置配置的资源是第二终端装置的资源。或者，当这个比特的取值为1时，表示为第一终端装置配置的资源是第二终端装置的资源。
可继续参考图10，为了避免第一终端装置和第二终端装置复用资源发送数据造成冲突，网络装置为第一终端装置发送用于配置资源的动态调度信令，如图10所示的资配置信息时，还可以通过第一指示信息通知第一终端装置是否检测至少一个第二终端装置的SCI。如果第一终端装置没有检测到任何第二终端装置的SCI，那么第一终端装置可以按照网络装置的调度指示进行发送数据。如果第一终端装置检测到了一个或者多个第二终端装置的SCI，则可以根据检测到的SCI判断与一个第二终端装置或者多个第二终端装置复用资源上有哪些资源是可以用来发送数据的，以避免与一个第二终端装置或多个第二终端装置发送数据时可能发生的冲突。
进一步地，第一指示信息可以用于指示第一终端装置检测至少一个第二终端装置的SCI的时域位置。在一种可能的方式中，一个第二终端装置对应一个检测SCI的时域位置。如果第一终端装置接收到第一指示信息，则可以根据第一指示信息所指示的时域位置检测至少一个第二终端装置的SCI。如果第一终端装置没有检测到SCI，则可以按照网络装置的调度信息在所配置的资源上发送数据。如果第一终端装置检测到了第二终端装置的SCI，则可以根据第二终端装置的SCI判断是否可以在网络装置配置的资源上发送数据。由于第一终端装置不一定检测第二终端装置的SCI，所以图10中也虚线示意SCI。
具体地，第一指示信息可以通过比特映射方式进行指示，例如，第一指示信息占用两个比特，这两个比特的取值用于指示第一终端装置在所分配的资源的什么位置开始检测至少一个第二终端装置的SCI。例如，第一指示信息为00，则可以表示第一终端装置不需要检测至少一个第二终端装置的SCI；第一指示信息为01，则可以表示第一终端装置在发送数据时，提前1个发送机会检测至少一个第二终端装置的SCI；第一指示信息为10，则可以表示第一终端装置在发送数据时，提前2个发送机会检测至少一个第二终端装置的SCI；第一指示信息为11，则可以表示第一终端装置在发送数据时，提前3个发送机会检测至少一个第二终端装置的SCI。作为另一种实施方式，第一指示信息也可能占用4个比特，例如，第一指示信息为0000，则可以表示第一终端装置不需要检测至少一个第二终端装置的SCI；第一指示信息为0010，则可以表示第一终端装置在发送数据时，提前2个发送机会检测至少一个第二终端装置的SCI。或者，第一指示信息也可以采用1个比特指示第一终端装置是否需要检测前1个发送机会的至少一个第二终端装置的SCI。
第一终端装置接收到来自网络装置的配置信息和第一指示信息之后，可以根据网络装置为第二终端装置配置的资源，以及接收的配置信息和第一指示信息，判断是否需要检测第二终端装置的SCI。即判断第一终端装置发送数据所占用的资源是否会与第二终端装置发送数据所占的资源重合。如果资源没有重合，则第一终端装置可以直接发送数；而如果资源重合，则第一终端装置需要检测第二终端装置的SCI，根据所检测的SCI判断在重合的资源上哪些资源上发送数据。
当然，如果网络装置提前将至少一个第二终端装置的配置信息发送给第一终端装置，那么第一终端装置接收了至少一个第二终端装置的配置信息后，接收到来自网络装置的用于指示第一资源的配置信息之后，可以根据至少一个第二终端装置的配置信息和第一资源配置信息确定第一资源是否为网络装置为至少一个第二终端装置配置的资源，并根据判断结果确定是否需要检测多个第二终端装置的SCI。如网络装置为第一终端装置配置的第一资源与网络装置为至少一个第二终端装置配置的资源重合，第一终端装置需要检测第二终端装置的SCI；如网络装置为第一终端装置配置的第一资源与网络装置为至少一个第二终端装置配置的资源不重合，第一终端装置不需要检测第二终端装置的SCI。
为了便于理解第一终端装置根据第一指示信息如何检测第二终端装置的SCI，下面将结合图11进行示意介绍。
请参见图11，为多个第一终端装置检测一个第二终端装置的SCI的示意图。图11以第二终端装置为UE1，多个第一终端装置分别为UE2、UE3、UE4和UE5为例。网络装置配置UE1使用的RV为(0，2，3，1)。网络装置配置UE2、UE3、UE4和UE5在UE1发送数据后的第1个发送机会、第2个发送机会、第3个发送机会可以进行发送数据。同时，网络装置配置UE2、UE3、UE4和UE5在UE1的第1个发送机会检测SCI。UE1的SCI中会携带UE1的重复传输或者下一个发送机会是否会发送数据的信息。如果UE1有数据发送，且网络装置为UE1配置的重复次数为2次。UE2在UE1的第1个发送机会检测UE1的SCI，如图11以箭头示意检测SCI的位置。由于UE1有数据发送，且重复次数为2次，那么UE1会占用第1个发送机会和第2个发送机会，所以UE2确定不能在第2个发送机会发送数据，即UE2无法发送数据。图11以第2个发送机会的标识“X”示意UE2不能在第2个发送机会发送数据。而对于UE3来说，UE3同样在UE1的第1个发送机会检测UE1的SCI，确定UE1会占用第1个发送机会和第2个发送机会，但是UE3可以从第3个发送机会开始发送数据，并没有与UE1占用的第1个发送机会和第2个发送机会冲突，所以UE3可以在第3个发送机会开始发送数据。同UE3一样，UE4可以确定在第4个发送机会可以发送数据。对于UE5来说，因为UE1在第5个发送机会还是可以开始发送数据，所以UE5需要在UE1的第1个发送机会和第5个发送机会检测UE1的SCI，再根据SCI确定哪些发送机会可以用来发送数据。
图11示意了多个第一终端装置检测一个第二终端装置的SCI的过程。实际中，一个资源可以对应多个终端装置，且这多个终端装置上的每个终端装置都可能发送数据，那么这多个终端设被配置的资源可以是相同时域资源下的多个不同的频域资源，也可以是相同频域资源下的多个不同的时域资源。在本申请实施例中，由于第一终端装置和第二终端装置复用第一资源，为了避免第一终端装置发送数据时没有资源可用，网络装置可以为第一终端装置配置多个资源。例如，网络装置为第一终端装置配置的资源可以是相同时域资源下的多个不同的频域资源，或者，相同频域资源下的多个不同的时域资源。
在这种情况下，第一指示信息可以用于指示第一终端装置是否检测至少两个第二终端装置的SCI。第一终端装置根据第一指示信息检测至少两个第二终端装置的SCI，并根据检测结果来确定第一终端装置与至少两个第二终端装置复用资源上的哪些资源可以用来发送数据。同样，第一指示信息可以用于指示第一终端装置检测至少两个第二终端装置中的每个第二终端装置的SCI的时域位置。
第一终端装置如果没有检测到任何一个第二终端装置的SCI，则第一终端装置根据网络装置的调度在所配置的资源上进行发送数据。如果第一终端装置有多个资源可用，则第 一终端装置可以从预设的选择资源方式在多个资源中选择一个资源进行发送数据。这种情况下，网络装置不需要给第一终端装置另外的指示，可以节约信令的开销。在一种可能的实施方式中，预设的选择资源方式可以是选择频域资源序号最低的资源、选择信道质量最好的资源、选择开始传输时间最早的资源。第一终端装置可以基于所进行的业务需求从预设的选择资源方式中选择一个资源。例如，如果第一终端装置所进行的业务要求时延低，则第一终端装置可以选择开始传输时间最早的资源，以尽量缩短传输业务的时延。又例如，如果第一终端装置所进行的业务要求较高的传输可靠性，则第一终端设可以选择信道质量最好的资源，以尽量保证所进行的业务的传输可靠性。
或者，如果第一终端装置检测到了至少两个第二终端装置中的部分第二终端装置或全部第二终端装置的SCI，根据所检测到的SCI确定有多个资源可用，则可以采用如上述的方式从预设的选择方式中在多个资源中选择一个资源进行发送数据，这里就不再赘述。如果第一终端装置根据所检测到的SCI确定有一个资源可用，则第一终端装置可以在这一个资源上发送数据。
又或者，如果第一终端装置检测到了至少两个第二终端装置中的部分第二终端装置或全部第二终端装置的SCI，根据所检测到的SCI确定没有资源可用，否则将与至少两个第二终端装置发生冲突，则第一终端装置不发送数据。
为了便于理解，请参见图12，示意了一个第一终端装置检测多个第二终端装置的SCI的过程。图12以包括两个第二终端装置为例，这两个第二终端装置分别为UE1和UE2，第一终端装置为UE3为例。网络装置配置UE1使用的RV为(0，3，0，3)，网络装置配置UE2使用的RV为(0，2，3，1)。网络装置配置UE3同时检测UE1和UE2在第1个发送机会的SCI，如图12以箭头示意检测SCI的位置。如果UE1和UE2在第1个发送机会均没有数据发送，则UE3可以选择UE1或UE2的资源。进一步地，由于UE1对应的资源序号小于UE2对应资源序号，则UE3可以优先选择UE1的资源来发送数据。
又例如，请参见图13，示意了一个第一终端装置检测一个第二终端装置的SCI的过程。图13以第一终端装置为UE2，第一终端装置为UE1为例。网络装置配置UE1使用的RV为(0，2，3，1)。网络装置配置UE2可发送数据的资源为第2个发送机会、第3个发送机会和第4个发送机会，并配置UE2检测UE1的SCI。UE2在UE1的第1个发送机会检测UE1的SCI，图13以箭头示意检测SCI的位置。如果UE2根据所检测的UE1的SCI确定UE1在第1个发送机会和第2个发送机会上发送数据，如图13阴影区域表示UE1在第1个发送机会和第2个发送机会上发送数据，那么UE2确定可以在第3个发送机会发送数据，也可以在第4个发送机会发送数据，不可以在第2个发送机会发送数据。UE2可以进一步选择预先发送数据的发送机会，例如第3个发送机会发送数据。图13通过“X”示意UE2对应的第2个发送机会用不可以发送数据，通过“Y”示意UE2对应的第3个发送机会用不可以发送数据。图13仅示意了一个第一终端装置检测一个第二终端装置的SCI的过程，实际上，一个第一终端装置检测多个第二终端装置中的每个第二终端装置的SCI的过程同图13是相同的，这里就不在举例了。
如前文所述，网络装置通过第一消息来指示为第一终端装置配置的第一资源是否还被配置给了至少一个第二终端装置，从而第一终端装置确定在至少一个终端装置没有在第一资源上发送数据时，可以在第一资源上发送数据，以尽量提高第一资源的利用率。同时，第一指示信息用于指示第一终端装置是否检测至少一个第二终端装置的SCI，从而避免第一终端装置和至少一个第二终端装置在第一资源发送数据可能产生的冲突。
下面结合附图介绍本申请实施例中用来实现上述方法的装置。因此，上文中的内容均可以用于后续实施例中，重复的内容不再赘述。
图14是本申请实施例提供的一种网络装置的结构示意图，如可以为基站的结构示意图。如图14所示，该基站可应用于如图1或图3所示的***中，执行上述方法实施例中网络装置的功能。基站140可包括一个或多个射频单元，如远端射频单元(remote radio unit,RRU)1401和一个或多个基带单元(baseband unit，BBU)(也可称为数字单元，digital unit，DU)1402。所述RRU1401可以称为收发单元、收发机、收发电路、或者收发器等等，其可以包括至少一个天线14011和射频单元14012。所述RRU1401部分主要用于射频信号的收发以及射频信号与基带信号的转换，例如用于向终端设备发送上述实施例中所述的第一消息。所述BBU1402部分主要用于进行基带处理，对基站进行控制等。所述RRU1401与BBU1402可以是物理上设置在一起，也可以物理上分离设置的，即分布式基站。

当终端装置开机后，处理器可以读取存储单元中的软件程序，解释并执行软件程序的指令，处理软件程序的数据。当需要通过无线发送数据时，处理器对待发送的数据进行基带处理后，输出基带信号至射频电路，射频电路将基带信号进行射频处理后将射频信号通过天线以电磁波的形式向外发送。当有数据发送到终端装置时，射频电路通过天线接收到射频信号，将射频信号转换为基带信号，并将基带信号输出至处理器，处理器将基带信号转换为数据并对该数据进行处理。
