Description

资源指示方法、装置和终端 技术领域
本申请涉及通信技术领域，尤其涉及一种资源指示方法、装置和终端。
背景技术
终端到终端(Device to Device，D2D)通信是一种基于侧行链路传输技术(Sidelink，SL)，与传统的蜂窝系统中通信数据通过基站接收或者发送的方式不同，D2D系统采用终端到终端直接通信的方式，具有更高的频谱效率以及更低的传输时延。车联网系统基于D2D传输技术，D2D通信可以包括车对车(Vehicle to Vehicle，简称“V2V”)通信或车辆到其他终端(Vehicle to Everything，V2X)通信。在新无线(New Radio，NR)-V2X中，需要支持自动驾驶，对车辆之间数据交互有更高的要求，如更高的吞吐量、更低的时延、更高的可靠性、更大的覆盖范围、更灵活的资源分配等。
在NR-V2X中，由于终端之间缺少协调，可能发生多个终端选择相同的时间资源，由于侧行通信中同一终端不能同时进行发送和接收操作，即存在半双工限制，上述多个终端之间无法接收对方的数据。另外，如果多个终端在同一个时刻触发资源选择或资源重选，多个终端会基于相同的信道检测信息进行资源选择，最终可能选择相同的时频资源或者部分重叠的时频资源，从而导致相互干扰。

具体实施方式
下面将结合附图对本申请实施例中的技术方案进行描述。
在V2X通信中，X可以泛指任何具有无线接收和发送能力的设备，例如但不限于慢速移动的无线装置，快速移动的车载设备，或是具有无线发射接收能力的网络控制节点等。在NR-V2X通信中，需要支持自动驾驶，对车辆之间数据交互有更高的要求，如更高的吞吐量、更低的时延、更高的可靠性、更大的覆盖范围、更灵活的资源分配等。
在目前第三代合作伙伴计划(3rd Generation Partnership Project，3GPP)中定义了两种进行侧行传输的传输模式：模式A和模式B，请参阅图1A和图1B，图1A为本申请实施例提供的一种传输模式为模式A的演示示意图，图1A为本申请实施例提供的一种传输模式为模式B的演示示意图。
模式A：终端的传输资源是由网络设备分配的，终端根据网络设备分配的资源，在侧行链路上进行数据传输；网络设备可以为终端分配单次传输的资源，也可以为终端分配半静态传输的资源。
模式B：车载终端在资源池中选取一个资源进行数据的传输。
在长期演进(Long Term Evaluation，LTE)-V2X中，支持广播传输方式。在NR-V2X中，需要支持自动驾驶。因此对车辆之间的数据交互提出了更高的要求，例如先不要更高的吞吐量、更低的时延、更高的可靠性、更大的覆盖范围、更灵活的资源分配等。在NR-V2X中，引入了单播和组播的传输方式。对于单播传输，其接收端终端只有一个终端，如图1C中，图1C为本申请实施例提供的一种单播传输方式的演示示意图，终端(user equipment，UE)1、终端2之间进行单播传输。对于组播传输，其接收端是一个通信组内的所有终端，或者是在一定传输距离内的所有终端，如图1D，图1D为本申请实施例提供的一种组播传输方式的演示示意图，终端1、终端2、终端3和终端4构成一个通信组，其中终端1发送数据，该组内的其他终端都是接收端终端。对于广播传输方式，其接收端是任意一个终端，如图1E，图1E为本申请实施例提供的一种广播传输方式的演示示意图，其中终端1是发送端终端，其周围的其他终端都是接收端终端。
在NR-V2X中，支持模式1和模式2的资源分配方式。在模式1中，侧行链路传输支持配置授权(Configured Grant，CG)的资源分配方式，即网络设备为终端分配侧行传输资源，即对应上述模式A，具体的，网络设备可以通过动态调度(dynamic scheduling，DS)的方式为终端分配侧行传输资源；或者网络设备可以为终端分配侧行(sidelink，SL)配置授权(configured grant，CG)传输资源。对于CG的资源分配方式，主要包括两种配置授权方式：第一类配置授权(type-1 configured grant)和第二类配置授权(type-2 configured grant)。
第一类配置授权：网络设备通过无线资源控制(radio resource control，RRC)信令为终端配置侧行传输资源，该RRC信令配置包括时域资源、频域资源、解调用参考信号(demodulation reference signal，DMRS)、调制编码方案(Modulation and Coding Scheme，MCS)等在内的全部传输资源和传输参数。当终端接收到该高层参数后，可立即使用所配置的传输参数在配置的时频资源上进行侧行传输。
第二类配置授权：采用两步的资源配置方式，即RRC+下行链路控制信息(Downlink Control Information，DCI)的方式。首先，由RRC信令配置包括时频资源的周期、冗余版本、重传次数、混合自动重复请求(Hybrid Automatic Repeat Request，HARQ)进程数等在内的传输资源和传输参数，然后由DCI激活第二类配置授权的传输，并同时配置包括时域资源、频域资源、MCS等在内的其他传输资源和传输参数。终端在接收到RRC信令时，不能立即使用该高层参数配置的资源和参数进行侧行传输，而必须等接收到相应的DCI激活并配置其他资源和传输参数后，才能进行侧行传输。此外，网络设备可以通过DCI去激活该配置传输，当终端接收到去激活的DCI后，不能再使用该传输资源进行侧行传输。
模式1要求发送终端必须位于网络设备的覆盖范围之内，而且和网络设备之间存在RRC连接，而如果终端位于网络设备的覆盖范围外或处于RRC空闲状态，则无法采用模式1。
在模式2中，终端在资源池自主选取传输资源进行侧行传输，即对应上述模式B。终端可以通过侦听的方式，在资源池中获取可用的资源集合。当终端从所述资源集合中选取一个传输资源进行数据传输时，所述终端可以预留下一次传输的传输资源，从而避免其他用户抢占该资源。
模式2适用于所有网络设备覆盖场景和和RRC连接状态。然而，在模式2中，由于终端之间没有任何协调，可能发生多个终端选择相同的时间资源，由于侧行通信中同一终端不能同时进行发送和接收操作，即存在半双工限制，上述多个终端之间无法接收对方的数据。另外，如果多个终端在同一个时刻触发资源选择或资源重选，多个终端会基于相同的信道检测信息进行资源选择，最终可能选择相同的时频资源或者部分重叠的时频资源，从而导致严重的相互干扰。因此，第一终端如何将一个资源集合发送给执行模式2资源选择的第二终端的问题需要解决。
针对上述问题，本申请实施例提出一种资源指示方法，应用于NR-V2X，其中，一个终端可以协助另外一个或多个终端的资源选择，具体的，第一终端可以将共享资源集合发送给第二终端，然后，第二终端在进行资源选择时，可以共享资源集合中的资源作为参考，降低半双工限制和资源碰撞的可能性。此外，本申请实施例所描述的终端可以包括各种具有无线通信功能的手持设备、车载设备、可穿戴设备(例如智能手表、智能手环、计步器等)、计算设备或连接到无线调制解调器的其他处理设备，以及各种形式的用户设备等等。为方便描述，上面提到的设备统称为终端。本申请实施例所描述的网络设备包括基站或核心网设备等。
请参阅图2A，图2A是本申请实施例提供的一种资源指示方法，该方法包括：
步骤201，第一终端通过第一信令向第二终端发送共享资源集合，所述共享资源集合用于指示侧行通信的传输资源。
其中，第一信令可以为一下任意一种：第一RRC信令，承载于物理侧行控制信道PSCCH上的侧行链路控制信息SCI格式0-1或承载于物理数据共享信道上的侧行链路控制信息SCI格式0-2。
其中，共享资源集合是包括用于辅助第二终端进行资源选择的资源集合，具体地，共享资源集合可以包括以下至少一种：至少一个第一类配置授权；至少一个第二类配置授权；第一终端在发送第一RRC信令时，预留时间超过最短预留时间N的频域资源；周期性预留的多个相同频域资源，等等，此处不做限定。
所述共享资源集合可以是通过第一RRC信令发送的，或者，所述共享资源集合可以是通过承载于物理侧行控制信道PSCCH上的侧行链路控制信息SCI中的特定比特域发送的，或者，所述共享资源集合可以是通过SCI格式0-2发送的。
第一终端将共享资源集合发送至第二终端后，第二终端可根据共享资源集合确定自身用于进行侧行通信的传输资源，从而，可避免与第一终端选择了相同的传输资源，造成严重的传输干扰。另外，第一终端可将其可能用于发送的传输资源发送到第二终端，第二终端在资源选择时可以避免选择共享资源集合中的资源，或避免选择和共享资源集合中的资源在时域上有重叠的资源，从而可以降低资源碰撞的概率，同时降低半双工带来的接收失败。
在一个可能的示例中，在所述第一终端通过第一信令向第二终端发送共享资源集合之前，所述方法还包括：
所述第一终端根据来自于网络设备的第一指示信息确定所述共享资源集合，其中，所述共享资源集合包括以下至少一种：至少一个第一类配置授权和至少一个第二类配置授权。
具体地，第一终端工作在模式1时，可根据来自于网络设备的第一指示信息确定共享资源集合，例如，第一设备可根据来自基站的第一指示信息确定共享资源集合。
其中，第一类配置授权可包括时域资源、频域资源、解调用参考信号(DMRS)、调制编码方案MCS等在内的全部传输资源和传输参数。
其中，第二类配置授权可包括时频资源的周期、冗余版本、重传次数、HARQ进程数等在内的传输 资源和传输参数；以及时域资源、频域资源、MCS等在内的其他传输资源和传输参数。
在一个可能的示例中，在所述第一终端通过第一信令向第二终端发送共享资源集合之前，所述方法还包括：
所述第一终端根据信道检测信息从资源池中选取所述共享资源集合，并周期性地占用所述共享资源集合中相同的频域资源。
具体地，第一终端工作在模式2时，可根据信道检测信息从资源池中选取共享资源集合，并周期性地占用共享资源集合中相同的频域资源。
在一个可能的示例中，所述第一信令为第一RRC信令。
在一个可能的示例中，所述共享资源集合包括所述第一终端在发送所述第一RRC信令时预留时间超过最短预留时间的频域资源。
其中，第一终端可通过第一RRC信令向第二终端发送共享资源集合，第一RRC信令例如可以是PC5RRC信令。
具体地，所述共享资源集合可包括第一终端在发送所述PC5 RRC信令时，预留时间超过最短预留时间N的频域资源，其中第一终端可根据自行配置或预先配置确定N的值，或者N的值可以由系统默认设定。
在本申请可能的示例中，若所述第一终端在一个资源预留周期内预留了多个频域资源，则所述共享资源集合包括所述多个频域资源及所述多个频域资源对应的资源预留周期之后时隙上的相同频域资源。
请参阅图2B，图2B为本申请实施例提供的一种第一终端通过第一RRC信令向第二终端发送共享资源集合的演示示意图，其中，对于周期性传输的业务，可预留周期性传输的传输资源，第一终端工作在模式2，第一终端根据信道检测结果选择资源，并且周期性的占用相同的频域资源，所述共享资源集合包含第一终端在发送所述PC5RRC信令时，预留时间超过N的频域资源，若第一终端在每个资源预留周期内预留了多个频域资源，上述多个频域资源及其对应的周期性预留的相同频域资源均属于共享资源集合。
可选地，从所述第一终端确定所述多个频域资源中的第一个频域资源至发送所述第一RRC信令之间的时间间隔小于或等于最大时间间隔，若所述第一终端没有确定的资源发送所述第一RRC信令，则第一终端触发资源重选。
具体实施中，第一终端从确定第一个频域资源到发送所述第一RRC信令之间的时间间隔小于或等于最大时间间隔T，如果第一终端没有确定合适的资源发送所述第一RRC信令，则第一终端触发资源重选，其中，第一终端可根据自行配置或预先配置最大时间间隔T的值，或者T的值可以由系统默认设定。
可见，第一终端通过将其可能用于发送的资源发送到第二终端，第二终端在资源选择时可以避免选择共享资源集合中的传输资源，或避免选择和共享资源集合中的资源在时域上有重叠的资源，从而可以降低资源碰撞的概率，同时降低半双工带来的接收失败。
在一个可能的示例中，在所述第一终端通过第一信令向第二终端发送共享资源集合之前，所述方法还包括：
所述第一终端根据来自于网络设备的第二指示信息确定初始资源集合；
根据所述初始资源集合确定所述共享资源集合，所述共享资源集合为所述初始资源集合的子集。
其中，初始资源集合为第一终端确定的包括多个候选资源的资源集合，具体实施中，第一终端可先根据网络设备的第二指示信息确定初始资源集合，然后从初始资源集合中确定出部分资源构成共享资源集合，然后将共享资源集合发送至第二终端。
在本可能的示例中，所述初始资源集合表示为一个或多个第一类配置授权，或者表示为一个资源池；所述共享资源集合表示为一个或多个第一类配置授权，或者表示为一个资源池。
其中，第一类配置授权可包括时域资源、频域资源、解调用参考信号(DMRS)、调制编码方案MCS等在内的全部传输资源和传输参数。
在本可能的示例中，所述共享资源集合中包括所述第一终端当前使用的侧行发送资源和未被所述第一终端使用的侧行资源。
具体实施中，第一终端可对当前使用的侧行发送资源和未被第一终端使用的侧行资源分别进行指示，从而，第二终端在接收到共享资源集合后，可优先选择不会与第一终端使用的侧行资源发生冲突的资源，从而可以避免和第一终端及第二终端之间的资源碰撞或半双工限制。
在一个可能的示例中，所述第一信令为承载于物理侧行控制信道PSCCH的侧行链路控制信令SCI。
在一个可能的示例中，所述SCI包括以下至少一种内容：

可选地，所述SCI的总比特数可以和SCI格式0-1的比特数不同；承载所述SCI的PSCCH占用的时频域资源大小可以与用于承载所述SCI格式0-1的PSCCH占用的时频域资源大小不同。
在一个可能的示例中，所述SCI中包括的比特域与SCI格式0-1中包括的比特域相同，所述SCI中包括的比特域与用于承载所述SCI的PSCCH占用的时频资源大小相同。
本申请可能的示例中，若所述第二终端接收到所述第一终端的第三RRC信令，所述第三RRC信令指示所述SCI0-1中预留比特处于激活状态，或者，来自于网络设备的配置信令或预配置信令指示当前资源池中所述SCI0-1的保留比特域处于激活状态，则所述第二终端将所述预留比特作为时频域预留资源预留周期个数。
例如，如果第二终端接收到SCI 0-1中指示的一个时频资源位于时隙n，预留周期P，保留比特域的十进制表示为D，则第二终端可认为第一终端预留了时隙n+P,n+2*P,…,n+(D+1)*P上的相同频域资源。
