Description

一种确定资源的方法及装置
本申请要求在2018年03月30日提交中国专利局、申请号为201810276348.1、发明名称为“一种确定资源的方法及装置”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，尤其涉及一种确定资源的方法及装置。
背景技术
车与外界的信息交换(vehicle to everything，V2X)，是未来智能交通运输系统的关键技术。V2X的应用可以包括车与车(vehicle to vehicle，V2V)、车与路侧基础设施(vehicle to infrastructure，V2I)、车与行人(vehicle to pedestrian，V2P)以及车与应用服务器(vehicle to network，V2N)。V2X的应用能够改善驾驶安全性、减少拥堵和车辆能耗、提高交通效率和车载娱乐信息等。
在V2X的应用中，终端与终端之间进行通信时，发送端在物理侧行链路控制信道(physical shared scheduling channel，PSCCH)上发送调度指示(scheduling assignment，SA)对选择占用的数据传输资源进行动态指示，接收端在SA所指示的资源上获取传输的数据。
终端传输SA的时域资源和频域资源，可以全部由基站通过动态信令或物理层信令指示，也可以由基站半静态配置。若时域资源和频域资源均通过动态信令或物理层信令指示，则基站向终端发送时域、频域资源的指示信息；发送端和接收端根据指示信息确定出基站配置的时频域资源。若SA的资源是由基站半静态配置的，则终端根据基站指示确定传输SA的时隙；发送端在该时隙上可用于传输SA的资源中，即SA候选资源池中，选择SA资源并发送SA；接收端在该时隙上的SA候选资源池所包含的资源上进行盲检，从而接收SA。
然而，由于第五代移动通信技术(the 5th generation，5G)相对于长期演进(long term evolution，LTE)的时域资源分配更加灵活多变，当SA配置在灵活的时域资源上时，根据现有技术无法确定SA的频域资源，因此，LTE中的终端确定SA资源的方法并不适用于5G通信系统中。
发明内容
本申请实施例提供一种确定资源的方法及装置，用于解决在时隙灵活多变的场景下确定SA资源的问题。
第一方面，本申请实施例提供了一种确定资源的方法，包括：
终端获取第一指示信息和第二指示信息，其中，第一指示信息用于指示该终端发送或接收SA的时隙，第二指示信息用于指示该时隙的时隙格式；终端根据时隙格式，确定该时隙上的SA资源。
具体地，时隙格式具体用于指示一个时隙中哪些符号用于上行传输、哪些符号用于下 行传输。
LTE中的每个时隙上的符号全部用于上行传输或全部用于下行传输，因此LTE中终端确定SA资源的方法不能沿用到时隙格式灵活多变的通信系统中。而在上述方法中，终端根据时隙格式进行SA资源的确定，使得该方法能够适用于时隙格式灵活多变的通信系统中。
在一种可能的实现方式中，终端根据时隙格式确定该时隙上的SA资源时，终端可以确定该时隙上SA的频域资源。具体地，终端占用上行符号传输SA，而基站将传输SA的时隙以及该时隙的时隙格式发送给终端，即基站通知终端传输SA的时域资源，因此，终端可以根据时隙格式进一步确定传输SA的频域资源，从而确定传输SA的资源。
在一种可能的实现方式中，终端根据时隙格式确定SA的频域资源时，可以先根据时隙格式确定第一数量，其中第一数量为SA在频域上占用的资源块(resource block，RB)的数量；终端根据第一数量确定SA的频域资源。
在上述实施例中，第一数量与时隙格式相关，而传输SA的频域资源与第一数量相关，终端可以根据第一数量与时隙格式之间的关系、传输SA的频域资源与第一数量之间的关系，确定出传输SA的频域资源。
在一种可能的实现方式中，终端根据时隙格式确定第一数量时，可以向根据时隙格式确定上述时隙中上行符号的数量(即第二数量)，然后根据第二数量，以及第二数量与第一数量的映射关系，确定第一数量。
时隙格式可以指示时隙上哪些符号用于上行传输，哪些符号用于下行传输，因此，终端可以根据时隙格式指示确定出上行符号的数量；而在上述实施例中，第二数量与第一数量之间存在既定的映射关系，该映射关系可以是映射表，终端可以根据第二数量在映射表中查找与对应的第一数量；该映射关系也可以是映射函数，终端可以根据第二数量以及映射函数计算出第一数量。
在一种可能的实现方式中，终端根据第二数量与第一数量的映射关系确定第一数量时，可以在第二数量大于等于预设阈值时，根据下述公式确定第一数量：

其中，x表示第二数量，y表示第一数量，A为常数，
Figure PCTCN2019080666-appb-000002
表示向下取整。
在一种可能的实现方式中，终端在确定上述时隙上SA的频域资源时，可以先确定该时隙上SA的资源集合，然后从该资源集合中选择发送SA的频域资源，或者，将该资源集合确定为对SA进行检测的资源。
若基站仅指示了终端传输SA的时隙，没有指示频域资源，则终端可以在该时隙上确定可用于传输SA的候选资源的集合。若终端为数据传输的发送端，则进一步从确定出的资源集合中选择发送SA的频域资源，例如，终端可以随机选择或按照预设的规则进行选择；若终端为数据传输的接收端，则在确定出的资源集合上进行盲检，检测发送端是否发送了SA。
在一种可能的实现方式中，终端确定上述时隙上SA的资源集合时，可以根据下述公式确定该时隙上第m个可用资源包含的RB：
n RB＝n CHRBstart+m×n CHsize+j，j＝0,1,…y-1
其中，n RB表示RB在频域上的编号，n CHRBstart表示子信道在频域上起始RB的编号， n CHsize表示一个子信道在频域上包含的RB的数量，m为大于等于0的整数，y表示所述第一数量。
上述实施例可以应用于传输SA和该SA调度的数据所占用的资源在频域上连续的情况。
在一种可能的实现方式中，终端确定上述时隙上SA的资源集合时，可以根据下述公式确定该时隙上第m个可用资源包含的RB：
Figure PCTCN2019080666-appb-000003
其中，n RB表示RB在频域上的编号，n CHRBstart表示子信道在频域上起始RB的编号，n CHsize表示一个子信道在频域上包含的RB的数量，m为大于等于0的整数，y表示所述第一数量。
上述实施例也可以应用于传输SA和该SA调度的数据所占用的资源在频域上连续的情况。
在一种可能的实现方式中，终端确定上述时隙上SA的资源集合时，可以根据下述公式确定该时隙上第m个可用资源包含的RB：
n RB＝n PSCCHstart+y×m+j，j＝0,1,…y-1
其中，n RB表示RB在频域上的编号，n PSCCHstart表示可用于传输SA资源的起始RB编号，m为大于等于0的整数，y表示所述第一数量。
上述实施例可以应用于传输SA和该SA调度的数据所占用的资源在频域上不连续的情况。
在一种可能的实现方式中，该方法还包括：终端获取第三指示信息，该第三指示信息用于所述SA的频域资源为所述时隙上第m个可用资源；终端可以根据下述公式确定所述时隙上第m个可用资源包含的RB：
n RB＝n CHRBstart+m×n CHsize+j，j＝0,1,…y-1；或者
n RB＝n CHRBstart+n×n CHsize+j，n＝k*m,k*m+1,…,k*m+k-1，
Figure PCTCN2019080666-appb-000004
Figure PCTCN2019080666-appb-000005
j＝0,1；或者
n RB＝n PSCCHstart+y×m+j，j＝0,1,…y-1；
其中，n RB表示RB在频域上的编号，n PSCCHstart表示可用于传输SA资源的起始RB编号，n CHsize表示一个子信道在频域上包含的RB的数量，y表示所述第一数量。
在上述实施例中，终端根据网络设备指示的m值确定SA的频域资源，而无需再确定SA的资源集合。
在一种可能的实现方式中，终端可以在该时隙中上行符号的数量大于或等于预设阈值，才进一步确定该时隙上传输SA的资源。
若一个时隙中没有上行符号或上行符号的数量过少，可能无法实现传输SA或传输的可靠性较差，终端则放弃在该时隙上传输SA；若上行符号的数量大于等于预设阈值，终端可以确定在该时隙上传输SA，并进一步确定该时隙上传输SA的资源。
在一种可能的实现方式中，上述映射关系可以是预先约定的，或者，也可以是基站半静态配置的。
第二方面，本申请实施例提供了一种确定资源的方法，包括：
终端获取第一指示信息和第二指示信息，其中，第一指示信息用于指示该终端发送或接收SA的时隙，第二指示信息用于指示该时隙的时隙格式；终端根据所述时隙格式，确定该时隙上所述SA所携带的侧行链路控制信息(sidelink control information，SCI)的格式，其中，不同的格式对应的SCI占用的比特数不同；终端根据SCI的格式，发送或检测SA。
在上述实施例中，终端根据基站指示的时隙以及该时隙的时隙格式，确定传输SA的时域资源，频域资源的确定方法可以与现有技术类似；然而，上述方法可能导致在不同时隙格式的情况下确定出的传输SA的资源占用的RB的数量不同，为了使得确定出的不同RB数量的资源均能够用于传输SA，可以采用不同数量的比特传输SCI。
在一种可能的实现方式中，终端在根据时隙格式确定SCI的格式时，可以先根据时隙格式确定该时隙中上行符号的数量；然后根据上行符号的数量，确定该时隙上传输SA所携带的SCI的格式。
在上述实施例中，一个时隙中上行符号的数量与SCI的格式之间存在对应关系，例如，若一个时隙中上行符号数量较多，则SCI所占用的比特数较多，反之，则占用的比特数较少。

具体实施方式
为了使本申请的目的、技术方案和优点更加清楚，下面将结合附图对本申请作进一步地详细描述。
在V2X的应用场景中，终端与终端之间进行通信的网络架构示意图可以如图1所示。终端1和终端2通过侧行链路(sidelink)进行通信，而侧行链路的资源可以根据基站等网络设备的指示确定。具体地，若终端1需要向终端2发送数据，则终端1作为发送端，在PSCCH上发送SA对占用的数据传输资源进行动态指示；终端2作为接收端，在SA所指示的资源上获取终端1发送的数据。
其中，本申请实施例中的基站可以用于将收到的空中帧与网际协议(internet protocol，IP)分组进行相互转换，作为无线终端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。基站还可用于协调对空中接口的属性管理。其中，在采用不同无线接入技术的通信系统中，具备基站功能的设备的名称可能会有所不同，例如，全球移动通信系统(global system for mobile communication，GSM)或码分多址(code division multiple access，CDMA)系统中的基站称之为基站(base transceiver station，BTS)、宽带码分多址(wideband code division multiple access，WCDMA)中的基站称之为节点B(node B)、LTE系统中的基站称之为演进型基站(evolutional node B，eNB)、NR系统中的基站称之为通用型基站(general node B，gNB)等。本申请实施例对此不进行不限定。
本申请实施例中的终端可以指用户设备(user equipment，UE)、接入终端、用户单元、用户站、移动站、移动台、远方站、远程终端、移动设备、用户终端、终端、无线通信设备、用户代理或用户装置。终端设备还可以是蜂窝电话、无绳电话、会话启动协议(session initiation protocol，SIP)电话、无线本地环路(wireless local loop，WLL)站、个人数字处理(personal digital assistant，PDA)、具有无线通信功能的手持设备、计算设备或连接到无线调制解调器的其它处理设备、车载设备、可穿戴设备，未来5G网络中的终端设备或者未来演进的公用陆地移动通信网络(public land mobile network，PLMN)中的终端设备等，本申请实施例对此并不限定。
一般来说，SA资源并不是固定的，其时域资源、频域资源可以分别由基站配置，或者，基站也可以仅指示SA的时域资源，频域资源由发送端自行选择。
SA资源与数据传输资源的分布情况，包括图2(a)和图2(b)所示的两种情况。
图2(a)所示的为SA资源(PSCCH可用于承载SA，因此PSCCH可占用的资源即 为SA可占用的资源)与该SA调度的数据所占用的资源在频域上连续的情况。例如，SA1所在的频域资源与SA1所调度的数据Data1所在的资源，在频域上连续；SA2所在的频域资源与SA2所调度的数据Data2所在的资源，在频域上连续；SA3所在的频域资源与SA3所调度的数据Data3所在的资源，在频域上连续；SA4所在的频域资源与SA4所调度的数据Data4所在的资源，在频域上连续。如图2(a)所示，一个子信道在频域上包括N 1个RB的SA资源和N 2个RB的数据资源，其中，N 1、N 2为预设的正整数，SA资源部分可以用于传输SA，但也可以用于传输数据(如Data1所占用的资源中即包含SA资源部分)，而数据资源部分可以用于传输数据，但不能用于传输SA。
图2(b)所示的为SA资源与该SA调度的数据所占用的资源在频域上不连续的情况。如图所示，可以用于传输SA的资源在频域上相对集中，且不可用于传输数据；可以用于传输数据的资源在频域上相对集中，且不可用于传输SA。其中，一个子信道在频域上包括N 3个RB，N 3为预设的正整数。
SA资源为上行传输资源。在现有技术中，一个子帧中包含的符号全部用于上行传输或全部用于下行传输，因此，基站在指示终端发送或接收SA的时域资源时，通常以子帧为单位进行指示。
在第五代移动通信技术(the 5th generation，5G)中，采用时隙取代子帧作为数据传输的单位。而5G中时隙的结构灵活多样，例如，一个时隙中包含的若干符号，可以全部用于上行传输；也可以全部用于下行传输；还可以令部分符号用于上行传输、部分符号用于下行传输，进一步地，还可以将部分符号设为未知(unknown)符号，即，这部分符号可以根据基站的调度指示用于上行或下行传输，若基站没有对未知符号进行调度指示，通常未知符号既不用于上行传输，也不用于下行传输。时隙格式可以表示上行符号、下行符号和未知符号的各种可能的组合。
因此，LTE中的终端确定SA资源的方法并不适用于5G通信系统中，终端如何确定SA资源成为亟待解决的问题。
因此，本申请实施例提供了一种确定资源的方法及装置，用于解决在时隙灵活多变的场景下确定SA资源的问题。
参见图3，为本申请实施例提供的确定资源的方法流程示意图，该方法可以应用于数据的发送端，也可以应用于数据的接收端。如图所示，该方法可以包括以下步骤：
步骤31、终端获取第一指示信息和第二指示信息。
其中，第一指示信息用于指示该终端发送或接收SA的时隙，第二指示信息用于指示该时隙的时隙格式。
可选地，第一指示信息可以携带在下行控制信息(downlink control information，DCI)中，以指示终端发送或者接收SA的时域资源。具体地，基站在物理下行控制信道(physical downlink control channel，PDCCH)上发送携带有第一指示信息的DCI，终端接收到DCI进而获取发送或者接收SA的时域资源。
可选地，第二指示信息可以是时隙格式指示信息(slot format information，SFI)。具体地，终端可以在组公共物理下行控制信道(group common PDCCH)上接收基站发送的SFI，从而获取第一指示信息所指示的发送或接收SA所在时隙的时隙格式。例如，可预先对时隙中的上行符号、下行符号、未知符号的多种组合进行编号，基站可以将时隙格式的编号发送给终端，终端根据时隙格式编号，即可确定该时隙中每个时隙符号为上行符号、下行 符号还是未知符号。
步骤32、终端根据上述时隙格式，确定该时隙上的SA的资源。
终端可以根据上述从第二信息获取到的时隙格式，确定第一指示信息所指示的发送或接收SA的时隙中哪些符号用于进行上行传输，即，确定出在该时隙中的哪些符号上发送或接收SA。
需要理解的是，在本申请的描述中，“第一”、“第二”等词汇，仅用于区分描述的目的，而不能理解为指示或暗示相对重要性，也不能理解为指示或暗示顺序。
在上述方法实施例中，终端根据时隙格式进行SA资源的确定，使得该方法能够适用于时隙格式灵活多变的通信系统中。
终端可以根据第一指示信息和第二指示信息直接确定出发送或接收SA的时域资源，此外，终端还可以根据时隙格式进一步确定上述时隙上发送或接收SA的频域资源。
在一种可能的实现方式中，终端在根据时隙格式确定第一指示信息指示的时隙上发送或接收SA的频域资源时，终端可以通过如图4所示的流程确定SA的频域资源。
步骤41、终端根据时隙格式确定SA在频域上占用的RB的数量。
为了描述方便，后面以“第一数量”表示SA在频域上占用的RB数量。
步骤42、终端根据确定出的第一数量确定SA的频域资源。
在上述实施例中，第一数量与时隙格式相关。例如，在不同时隙格式的时隙上发送的SA，占用的RB数量可以不同。
可选地，上述步骤41还可以进一步包括如图5所示的步骤411和步骤412。
步骤411、终端根据时隙格式确定第一指示信息所指示的时隙中包含的上行符号的数量。
例如，若第二指示信息中包含时隙格式编号，则终端可根据时隙格式编号确定出该时隙上每个符号为上行符号、下行符号还是未知符，从而可以进一步确定出该时隙中上行符号的数量。
为了描述方便，后面以“第二数量”表示一个时隙中包含的上行符号的数量。
可选地，若确定出的第二数量大于或等于预设阈值，则继续执行步骤412；若确定出的第二数量小于或等于预设阈值，可能无法保证SA传输的可靠性，则不再确定SA的资源，即，终端放弃在该时隙上发送或接收SA。
步骤412、终端根据第二数量，以及第二数量与第一数量的映射关系，确定出第一数量。
第二数量与第一数量的映射关系可以用于根据已知的第二数量确定出第一数量。可选地，上述第二数量与第一数量的映射关系，可以是预先约定的，也可以是基站半静态配置的。
在一种可能的实现方式中，可以预先对第二数量的每个取值，设置与其对应的第一数量的数值；或者，也可以预先对第二数量划分取值范围，为每个第二数量的每个取值范围设置对应的第一数量的数值。
以一个时隙中包含14个符号为例，上述第二数量与第一数量的映射关系可以如表1所示。
表1
第二数量(x) 第一数量(y)
14 2
7<x<14 3
7 4
3<x<7 6
以表1为例，若终端根据时隙格式确定出第一指示信息所指示的时隙中包含14个上行符号，即该时隙中的符号全部用于上行传输，此时，SA在频域上占用的RB的数量可以与LTE中相同，即在频域上占用2个RB；若确定出时隙中包含7个上行符号，与LTE中发送SA的资源相比，只包含7个上行符号的时隙中可发送SA的时域资源减半，因此，可以令SA的资源在频域上占用的RB数量翻倍，即在频域上占用4个RB，使得SA占用的总RB数量与LTE中相同；若确定出时隙中包含的上行符号数量小于等于3，可能无法保证SA传输的可靠性，此时，终端可以放弃在该时隙上发送或接收SA，即上述预设阈值为3。
应当理解，表1中给出的数值仅为举例，本申请实施例并不对第一数量、第二数量以及预设阈值的具体数值进行限定。此外，上述实施例中SA所占用的总RB数量也可以与LTE中的不同，本申请对此不做限制。
在另一种可能的实现方式中，第二数量与第一数量之间的映射关系，也可以通过映射函数表示。例如，终端确定出第二数量，并确定第二数量大于等于预设阈值时，根据公式(1)确定第一数量：
Figure PCTCN2019080666-appb-000009
其中，x表示第二数量，y表示第一数量，A为常数，
Figure PCTCN2019080666-appb-000010
表示向下取整。可选地，也可以用向上取整替换上述公式中的向下取整，或者，还可以通过四舍五入等方式取整。
为了使公式(1)成立，x应为大于等于1的整数，即，若x<1，则无法在该时隙上发送或接收SA。因此，上述预设阈值可以取大于等于1的数值。若终端确定出的第二数量小于预设阈值，则放弃在该时隙上发送或接收SA。
在一种可能的实现方式中，基站仅向终端指示了发送或接收SA的时域资源，即，仅向终端发送的第一指示信息和第二指示信息，而没有指示终端发送或接收SA的频域资源。在这种情况下，上述步骤42还可以进一步包括如图6所示的步骤421和步骤422。
步骤421、终端确定第一指示信息所指示的时隙上SA的资源集合。
步骤422、终端从该资源集合中选择发送SA的频域资源，或者，将该资源集合确定为对SA进行检测的资源。
由于基站没有指示终端发送或接收SA的频域资源，因此，终端可以先确定出该时隙上可用于发送或接收SA的候选资源的集合，然后，发送端从候选资源集合中选择出一个候选资源并发送SA，而接收端可以在确定出的全部候选资源上，检测SA。
如前所述，与一个时隙中的符号全部为上行符号相比，若上行符号数量减小，即SA在时域上占用的资源减少，为了保证SA传输的可靠性，可以增加SA在频域上占用的资源。当SA在频域上占用的资源增加时，有两种实现方式，一种是：增加频域上SA能够占用的资源，使得能够发送或接收的SA的最大数目不变；另一种是：SA能够占用的频域 资源不变，但能够发送或接收的SA的最大数目减少。下面结合图7至图10进行详细说明。
实现方式1：
若SA资源与该SA调度的数据的资源在频域上连续，即如图7(a)所示的资源分布情况，且保证能够发送或接收的SA的最大数目不变即频域上SA能够占用的资源可变时，SA的资源可以如图7(b)所示。
在上述情况下，终端在确定SA的资源集合时，可以根据公式(2)确定第一指示信息指示的时隙上的第m个可用资源包含的RB：
n RB＝n CHRBstart+m×n CHsize+j，j＝0,1,…y-1  (2)
其中，n RB表示RB在频域上的编号，n CHRBstart表示子信道在频域上起始RB的编号，n CHsize表示一个子信道在频域上包含的RB的数量，m为大于等于0的整数，y表示第一数量。
具体地，m的取值范围与总资源在频域上的RB数量存在如下关系：
Figure PCTCN2019080666-appb-000011
其中，m max表示m能够取的最大值，B表示频域上总的RB数量。例如，若m的最大取值为9，则表示m∈{0,1,2,3,4,5,6,7,8,9}；终端可以根据m的取值范围，将m的每个可选值代入公式(2)中得到SA的候选资源，从而获得包含10个候选资源的资源集合。
如图7(b)所示，在频域上，为了保证能够发送或接收的SA的最大数目不变，一个子信道中SA占用的RB数与数据可占用的RB数，可以随第一数量的变化而变化。而不论根据时隙格式确定出的第一数量是多少，m的取值范围不变。
在一些实施例中，B的取值是预先约定的或是由基站发送给终端的，终端根据公式(3)确定m的取值范围。在另外一些实施例中，m的最大取值是预先约定的或是由基站发送给终端的。
应当理解，虽然图7(a)和图7(b)中以一个时隙中包含14个符号、其中7个为上行符号为例，但上述实施例并不限于应用在一个时隙包含14个符号的场景中，对于一个时隙包含其他数量符号或者其他时隙格式的场景也同样适用。
实现方式2：
若SA资源与该SA调度的数据的资源在频域上连续，即如图8(a)所示的资源分布情况，且不增加频域上SA能够占用的资源即能够发送或接收SA的最大数目可变时，SA的资源可以如图8(b)所示。
如图8(b)所示，一个时隙中包含14个符号、其中7个为上行符号，且根据第二数量与第一数量的映射关系确定出SA在频域上占用4个RB。由于上行符号的数量为7，此时，SA在频域上占用的RB数量，为一个时隙中全部为上行符号时在频域上占用RB数量的2倍，即在频域上占用两个子信道中可用于发送SA的RB。若发送端选择在子信道0和子信道1上可用于传输SA的资源上发送SA，则接收端在子信道0和子信道1上可用于传输SA的资源上接收SA，并根据该SA所指示的资源接收发送端发送的数据。
当然，图8(b)所示的仅为本申请实施例的一个特例。为了满足不增加频域上SA能够占用的资源这一条件，终端在确定SA的资源集合时，可以根据公式(4)确定第一指示信息指示的时隙上第m个可用资源包含的RB：
Figure PCTCN2019080666-appb-000012
Figure PCTCN2019080666-appb-000013
其中，n RB表示RB在频域上的编号，n CHRBstart表示子信道在频域上起始RB的编号，n CHsize表示一个子信道在频域上包含的RB的数量，m为大于等于0的整数，y表示第一数量。m取值范围的确定方法与实施例1中的确定方法类似，此处不再赘述。
由于上述实施例中为了不增加频域上SA能够占用的资源，使得公式(4)中n的取值范围随第一数量的变化而变化，即确定出的SA资源集合中包含的候选SA资源的数量随着变化。
实现方式3：
若SA资源与该SA调度的数据的资源在频域上不连续，即如图9(a)所示的资源分布情况，且保证能够发送或接收的SA的最大数目不变即频域上SA能够占用的资源可变时，SA的资源可以如图9(b)所示。
在上述情况下，终端在确定SA的资源集合时，可以根据公式(5)确定第一指示信息指示的时隙上第m个可用资源包含的RB：
n RB＝n PSCCHstart+y×m+j，j＝0,1,…y-1  (5)
其中，n RB表示RB在频域上的编号，n PSCCHstart表示可用于发送或接收的SA资源的起始RB编号，m为大于等于0的整数，y表示第一数量。
在上述实施例中，由于保证能够发送或接收SA的最大数目不变，因此，不论根据时隙格式确定出的第一数量是多少，m的取值范围不变。m的最大值可以为是预先约定的或是由基站发送给终端的。
实现方式4：
若SA资源与该SA调度的数据的资源在频域上不连续，即如图10(a)所示的资源分布情况，且不增加频域上SA能够占用的资源即能够发送或接收SA的最大数目可变时，SA的资源可以如图10(b)所示。
在上述情况下，终端在确定SA的资源集合时，也可以根据公式(5)确定第一指示信息指示的时隙上第m个可用资源包含的RB。
然而，与实施例3不同的是，m的取值范围不再是固定不变的，而是随第一数量的变化而变化。如图10(a)和10(b)所示，当时隙格式不同时，频域上SA能够占用的RB数量不变，但能够发送或接收的SA的最大数量即m的最大值随之改变。
具体地，m的取值范围受到SA可占用的总频域资源的限制，即：
Figure PCTCN2019080666-appb-000014
其中，m max表示m能够取的最大值，C表示SA在频域上可用RB数量，y表示第一数量。在一些实施例中，B的取值是预先约定的或是由基站发送给终端的，终端根据公式(6)确定m的取值范围。
上述实现方式1至4，提供了不同场景下终端确定SA的资源集合的示例。对于发送端来说，在确定出SA的资源集合后，还需要从资源集合中选择出最终发送SA的资源，例如，终端可以随机选择或按照预设的规则进行选择。而对于接收端来说，则将所述资源集合确定为对SA进行检测的资源，例如，终端可以在确定出的资源集合上进行盲检，以接收发送端发送的SA。
在另外一些实施例中，基站不仅向终端指示了时域资源，还可以进一步向终端指示频 域资源。例如，基站可以将上述实现方式1至4中m的值发送给终端，终端则根据m值确定发送或接收SA的频域资源，而不再需要将m的每个可能的取值均代入公式从而确定出资源集合。
基于相同的技术构思，本申请实施例还提供了一种配置资源的方法。在该方法中，网络设备向终端发送第一指示信息和第二指示信息，其中，第一指示信息用于指示所述终端发送或接收调度指示SA的时隙，第二指示信息用于指示所述时隙的时隙格式。上述方法使得终端能够根据第一指示信息和第二指示信息确定SA的资源，即，使得终端能够执行前述确定资源的方法实施例。
在一种可能的实现方式中，网络设备除了指示终端发送或接收SA的时域资源，还可以进一步指示SA的频域资源。具体地，网络设备可以根据所述时隙格式，确定所述时隙上的所述SA的频域资源，并向终端发送第三指示信息，该第三指示信息用于指示确定出的SA频域资源。
在一种可能的实现方式中，网络设备在根据时隙格式确定SA频域资源时，可以先根据时隙格式确定第一数量，所述第一数量为所述SA在频域上所占用的资源块RB的数量；然后根据所述第一数量，确定所述时隙上的所述SA的频域资源。
网络设备在确定第一数量的方法，可以与前述实施例中终端确定第一数量的方法类似，可先根据时隙格式确定第二数量，所述第二数量为所述时隙中上行符号的数量；然后根据所述第二数量与第一数量的映射关系，确定第一数量。可选地，网络设备在确定出的第二数量大于或等于预设阈值时，才进一步确定第一数量。
具体地，网络设备根据第二数量与第一数量的映射关系确定第一数量的过程，可以与前述终端确定第一数量的方法相同，此处不再赘述。
在一种可能的实现方式中，网络设备发送的第三指示信息，可以用于指示SA的频域资源为所述时隙上第m个可用资源，具体地，第m个可用资源所包含的RB，可以与前述终端确定SA频域资源的实现方式1至实现方式4相同。网络设备将m的取值发送给终端，以使终端根据m值确定发送或接收SA的RB，而无需再计算可发送或接收SA的资源集合。
在一种可能的实现方式中，所述第二数量和第一数量的映射关系是预先约定的，或者是网络设备半静态配置的。
为了解决时隙灵活多变的场景下发送或接收SA的问题，本申请实施例还提供了一种确定资源的方法，该方法可以包括如图11所示的步骤：
步骤111、终端获取第一指示信息和第二指示信息。
其中，第一指示信息用于指示该终端发送或接收SA的时隙，第二指示信息用于指示该时隙的时隙格式。
如前所述，第一指示信息可以为DCI，第二指示信息可以为SFI。
步骤112、终端根据上述时隙格式，确定该时隙上SA所携带的SCI的格式。其中，不同的格式对应的SCI占用的比特数不同。
具体地，SA中携带的SCI用于指示该SA所调度数据的资源位置。
步骤113、终端根据上述SCI的格式，发送或检测SA。
在上述方法中，终端根据基站指示的时隙以及该时隙的格式，确定发送或接收SA的时域资源，频域资源的确定方法可以与现有技术类似。然而，当时隙格式不同时，可能导致确定出的SA资源占用的总RB数量不同。为了使得确定出的不同RB数量的资源均能够 用于发送SA，SA中携带的SCI可以占用不同数量的比特。
在一种可能的实现方式中，终端在根据时隙格式确定SA中SCI的格式时，可以先根据时隙格式确定时隙中上行符号的数量，然后根据上行符号的数量，确定在该时隙上发送的SA中的SCI所占用的比特数。在该实施例中，SCI所占用的比特数与时隙中上行符号的数量相关，例如，若一个时隙中上行符号数量较多，则SCI所占用的比特数较多，反之，则占用的比特数较少。
可选地，当SCI占用的比特数量不同时，SCI所调度数据资源的粒度可以不同。例如，若SCI所占用的比特数量较多，在调度数据资源时，可以RB为单位进行调度；若SCI所占用的比特数量较少，在调度数据资源时，可以4个RB为单元进行调度。
在终端与终端进行通信时，接收端和发送端都可以根据上述方法确定SA中SCI的格式，从而根据SCI格式，发送或检测SA。
