图1示出本申请实施例可应用的一种无线通信系统的框图。无线通信系统包括终端11和网络侧设备12。
其中，终端11可以是手机、平板电脑(Tablet Personal Computer)、膝上型电脑(Laptop Computer)或称为笔记本电脑、个人数字助理(Personal Digital Assistant，PDA)、掌上电脑、上网本、超级移动个人计算机(ultra-mobile personal computer，UMPC)、移动上网装置(Mobile Internet Device，MID)、增强现实(augmented reality，AR)/虚拟现实(virtual reality，VR)设备、机器人、可穿戴式设备(Wearable Device)、车载设备(VUE)、行人终端(PUE)、智能家居(具有无线通信功能的家居设备，如冰箱、电视、洗衣机或者家具等)、游戏机、个人计算机(personal computer，PC)、柜员机或者自助机等终端侧设备，可穿戴式设备包括：智能手表、智能手环、智能耳机、智能眼镜、智能首饰(智能手镯、智能手链、智能戒指、智能项链、智能脚镯、智能脚链等)、智能腕带、智能服装等。需要说明的是，在本申请实施例并不限定终端11的具体类型。
网络侧设备12可以包括接入网设备或核心网设备，其中，接入网设备也可以称为无线接入网设备、无线接入网(Radio Access Network,RAN)、无线接入网功能或 无线接入网单元。接入网设备可以包括基站、WLAN接入点或WiFi节点等，基站可被称为节点B、演进节点B(eNB)、接入点、基收发机站(Base Transceiver Station，BTS)、无线电基站、无线电收发机、基本服务集(Basic Service Set，BSS)、扩展服务集(Extended Service Set，ESS)、家用B节点、家用演进型B节点、发送接收点(Transmitting Receiving Point，TRP)或所述领域中其他某个合适的术语，只要达到相同的技术效果，所述基站不限于特定技术词汇，需要说明的是，在本申请实施例中仅以NR系统中的基站为例进行介绍，并不限定基站的具体类型。
为方便理解，先对本申请实施例的应用场景、所涉及的相关技术、概念进行介绍。
本申请实施例所提供的技术方案可以应用于旁链路传输场景，如旁链路定位场景。如图2所示，终端1与终端2、终端3、终端4之间可以通过旁链路进行旁链路传输，如发送/接收/测量旁链路信道或信号，同时，终端1与网络侧设备之间可以通过上行链路(Uplink)和下行链路(Downlink)进行通信。
随着通信技术的快速发展，旁链路通信也逐渐发展起来。长期演进系统支持旁链路传输，即终端之间不通过网络侧设备直接在物理层上进行数据传输。长期演进系统旁链路是基于广播进行通讯的，虽然可用于支持车联网的基本安全类通信，但不适用于其他更高级的V2X业务。5G新空口系统支持更加先进的旁链路传输设计，例如，单播、多播或组播等，从而可以支持更全面的业务类型。
在R16标准中，新空口旁链路包括如下信道：
物理旁链路控制信道(physical sidelink control channel，PSCCH)；
物理旁链路共享信道(physical sidelink shared channel，PSSCH)；
物理旁链路广播信道(physical sidelink broadcast channel，PSBCH)；
物理旁链路反馈信道(physical sidelink discovery feedback channel，PSFCH)。
其中，物理旁链路共享信道以子信道(sub-channel)为单位进行资源分配，频域上采用连续的资源分配方式。物理旁链路控制信道的时域资源为高层配置的符号数，频域大小为高层配置的参数，且物理旁链路控制信道的频域资源限制小于或等于一个子信道的大小，且物理旁链路控制信道位于物理旁链路共享信道的最低子信道的范围内，如图3所示，其中，AGC表示自动增益控制(Automatic Gain Control)，GP表示保护时隙(Guard Period)。
新空口旁链路的资源分配和数据收发都在资源池内完成，终端行为都是基于资源池来定义的。旁链路系统中，终端在旁链路载波或旁链路带宽部分(Bandwidth Part，BWP)上的行为是由终端在每一个资源池上行为的集合组成的。这些行为包括监听(sensing)、物理旁链路控制信道/物理旁链路共享信道的发送和检测、物理旁链路反馈信道的发送和检测等。
在频域上，资源池是定义在一个带宽部分的内部。在一个给定的载波上，可以 为终端配置一个或多个资源池。终端可以在一个资源池内发送，或者在一个资源池内接收。对于资源池不进行传输类型的区分，单播、组播和广播可以共享资源池。资源池内频域的基本单位是子信道，资源池由多个连续的子信道构成，每个子信道由连续的多个物理资源块(Physical Resource Block，PRB)构成。
每个资源池在时域周期性地出现，周期为10.24s。在10.24s内通过相关技术中的具体方式确定属于资源池的时隙。不同的资源池包含的时隙数以及时隙排布可以不同。
对于新空口旁链路资源分配方式，新空口车联网定义了两种资源分配模式，一种是mode1，mode1为基站调度资源；另一种是mode2，mode2是终端自己决定使用什么资源进行传输。此时资源信息可能来自基站的广播消息或者预配置的信息。如果终端工作在基站范围内，并且与基站有无线资源控制(Radio Resource Control，RRC)连接，则可以工作在mode1和/或mode2。如果终端工作在基站范围内，但与基站没有RRC连接，则只能工作在mode2。如果终端在基站范围外，那么只能工作在mode2，根据预配置的信息来进行V2X传输。
对于mode 2，一种具体的工作方式可以如下：
1)发送终端在资源选择被触发后，首先确定资源选择窗口，资源选择窗口的下边界在资源选择触发后的T1时间，资源选择窗口的上边界在触发后的T2时间，其中T2是终端实现的方式在其传输块(Transport Block，TB)传输的分组时延预算(Packet Delay Budget，PDB)内选择的值，T2不早于T1。
2)终端在资源选择之前，需要确定资源选择的备选资源集合(candidate resource set)，将资源选择窗口内的资源上测量的参考信号接收功率(Reference Signal Receiving Power，RSRP)与相应的参考信号接收功率门限(RSRP threshold)做对比，如果参考信号接收功率低于参考信号接收功率门限，那么该资源可以纳入备选资源集合。
3)资源集合确定后，终端随机在备选资源集合中选择传输资源。另外，终端在本次传输可以为接下来的传输预留传输资源。
新空口车联网支持链式的资源预留方式，也就是，一个旁链路控制信息(Sidelink Control Information，SCI)可以预留当前的资源，最多可以再额外预留两个资源，在下一个资源中，可以再指示两个预留资源。在资源选择窗口内，可以采用动态预留的方式持续预留资源。
R18标准将引入旁链路定位参考信号(Sidelink Positioning Reference Signal，SL PRS)，可能会引入旁链路定位参考信号专用的资源池(resource pool)，而旁链路定位参考信号将使用这个资源池中的资源进行传输。进一步的，这个专用的资源池可能仅包含旁链路定位参考信号，以及物理旁链路控制信道，如物理旁链路控制信道可以用于调度/指示旁链路定位参考信号。
因为物理旁链路控制信道承载的数据量有限，可能无法承载全部的旁链路定位参考信号配置信息，所以可以考虑通过另一个资源池内的物理旁链路控制信道/物理旁链路共享信道承载旁链路定位参考信号配置信息。
同时，因为物理旁链路控制信道承载的数据量有限，也可能无法承载旁链路定位参考信号相关的测量上报信息，所以可以考虑通过另一个资源池内的物理旁链路控制信道/物理旁链路共享信道承载旁链路定位参考信号相关的测量上报信息。
基于上述描述，将出现跨资源池指示或调度的情况：
旁链路定位参考信号指示信息调度/指示旁链路定位参考信号，旁链路定位参考信号指示信息与旁链路定位参考信号位于不同的资源池；
旁链路定位参考信号测量上报请求指示上报资源，旁链路定位参考信号测量上报请求与上报资源位于不同的资源池。
而跨资源池指示时，至少存在如下问题：
资源池标识，如资源池ID本质是针对终端(per-UE)的，类似于Uu接口终端的服务小区索引(serving cell index)，对于两个Uu ID，cell 0、1、2……，可能表示完全不同的小区、频点、带宽等。具体如何达到终端间正确理解跨资源池指示还需要考虑更多细节问题。
不同资源池时域和频域指示的理解需要明确，比如pool 1的slot 2可能是物理(或称为实际)的slot 4，pool 2的slot 2可能是物理的slot 15。目前旁链路控制信息指示是在资源池内定义的，也就是这里的slot 2，这样定义的时隙也可称为逻辑时隙。如果是跨资源池调度，指示slot 2在pool 1内对应的物理位置，与在pool 2内对应的物理位置是不同的。

其中，配置标识与旁链路定位参考信号资源池有关。旁链路定位参考信号资源池内可以预配置多个旁链路定位参考信号资源，每个旁链路定位参考信号资源对应配置标识。接收终端可以根据资源池信息先明确旁链路定位参考信号所在的资源池，才能进一步根据配置标识确定对应的旁链路定位参考信号资源。

在旁链路定位参考信号为半静态或周期性发送的情况下，在一个旁链路定位参考信号周期内的旁链路定位参考信号的发送次数，即如果旁链路定位参考信号为半静态(半持续)或周期性的，则旁链路定位参考信号的发送次数可以表示一个旁链路定位参考信号周期的就旁链路定位参考信号的发送次数，不同次旁链路定位参考信号的发送可以分别占据不同的时隙。
(8)旁链路定位参考信号的周期。如果旁链路定位参考信号为半静态(半持续)或周期性的，则第一信息可以包含此项。旁链路定位参考信号的周期的长度可以是基于逻辑时隙的，或者是绝对时间的。绝对时间可以是绝对时隙，或者毫秒、秒等时间单元。其中，逻辑时隙基于旁链路定位参考信号所在资源池确定。
其中，旁链路定位参考信号的周期可以基于旁链路定位参考信号资源池，比如周期为n slots，n slots为旁链路定位参考信号资源池的逻辑时隙。
(9)旁链路定位参考信号的时隙所在位置。
时隙所在位置可以基于旁链路定位参考信号资源池计算。比如旁链路定位参考信号的时隙位置与资源池逻辑时隙有关，只有获得了旁链路定位参考信号资源池信息，逻辑时隙才有意义。
如果旁链路定位参考信号占用时隙为一个，则旁链路定位参考信号的时隙所在位置被指示为一个时隙的位置。

指示旁链路定位参考信号的起始时隙位置、后续每个时隙位置相对于起始时隙位置的偏移；根据相对于起始时隙位置的偏移即可确定后续每个时隙位置；
分别指示旁链路定位参考信号的每个时隙的位置。
即旁链路定位参考信号占用的时隙为1个时，指示该1个时隙的位置。旁链路 定位参考信号占用的时隙有多个时，如有N个，N>1，可以仅指示N个时隙中起始时隙位置，以及其他N-1个时隙的时隙位置相对于起始时隙位置的偏移。还可以分别指示N个时隙中每个时隙的位置。
如果旁链路定位参考信号为半静态(半持续)或周期性的，则在一个旁链路定位参考信号周期内，旁链路定位参考信号占用的时隙为1个时，指示该1个时隙的位置，或者，在一个旁链路定位参考信号周期内，旁链路定位参考信号占用的时隙为N个，N>1，仅指示起始时隙位置，以及其他N-1个时隙的时隙位置相对于起始时隙位置偏移，或者，指示N个时隙中每个时隙的位置。
接收到第一信息的终端，即接收终端，可以根据起始时隙位置和/或频域位置，在旁链路定位参考信号的资源池内接收起始旁链路定位参考信号。
如果根据本方式确定的时隙不是旁链路定位参考信号资源池内的逻辑时隙，则可以顺延下一个逻辑时隙作为旁链路定位参考信号的时隙。
在本申请实施例中，旁链路定位参考信号的起始时隙位置，或者旁链路定位参考信号的每个时隙的位置，或者旁链路定位参考信号占用的一个时隙的位置，是通过以下至少之一的方式指示的：

直连帧号索引、系统帧号索引、时隙索引中至少之一是基于旁链路定位参考信号所在的资源池，或者是基于旁链路定位参考信号所在的资源池的带宽部分或者载波。
如果旁链路定位参考信号为半静态(半持续)或周期性的，则旁链路定位参考信号的时隙所在位置可以仅通过时隙索引表示。表示起始时隙位置相对于DFN 0(SFN 0)slot 0的偏移，或者相对于资源池逻辑slot 0的偏移。
旁链路定位参考信号时隙相对于参考时隙的偏移是基于旁链路定位参考信号的资源池确定的，或，旁链路定位参考信号时隙相对于参考时隙的偏移是基于旁链路定位参考信号的时隙对应的子载波确定的，即旁链路定位参考信号时隙相对于参考时隙的偏移为逻辑时隙偏移或者实际时隙偏移，其中，逻辑时隙偏移是基于旁链路定位参考信号的资源池确定的，和/或，实际时隙偏移是基于旁链路定位参考信号的时隙对应的子载波确定的，表示了真实的时域位置间隔。旁链路定位参考信号时隙相对于参考时隙的偏移可以是直接指示的，还可以是在资源池中预配置多个选择，指示其中一个选择。另外，旁链路定位参考信号时隙相对于参考时隙的偏移可以通过时间资源指示值(Time resource indication value，TRIV)的方式指示。比如，时隙偏移分布在参考时隙后的W个时隙内。
参考时隙可以包括以下至少之一：
第一信息所在的时隙(或实际时隙)；可选的，第一信息所在的时隙为实际时隙；可选的，可以由逻辑时隙索引换算得到；

不早于目标时隙的旁链路定位参考信号的资源池中的第一个逻辑时隙，目标时隙为基于旁链路定位参考信号的子载波间隔和/或定时换算后的第一信息所在的时隙(或实际时隙)。
后续每个时隙位置相对于起始时隙位置的偏移可以为基于旁链路定位参考信号的资源池的逻辑时隙偏移，或者为实际时隙偏移。
后续每个时隙位置相对于起始时隙位置的偏移还可以是根据时间资源指示值的方式指示的。比如，N个旁链路定位参考信号时隙分布在W个时隙内，通过时间资源指示值(TRIV)的方式可以确定W个时隙内N个旁链路定位参考信号时隙分别对应的位置。W个时隙从旁链路定位参考信号的起始时隙开始。
(10)旁链路定位参考信号的时隙内符号位置，可以包括起始符号位置和符号数量至少之一。
(11)旁链路定位参考信号的窗口配置。旁链路定位参考信号窗口(SL PRS window)用于指示第一终端和/或第二终端在这个窗口内测量旁链路定位参考信号或侦听旁链路定位参考信号，如侦听旁链路定位参考信号资源池内的物理旁链路控制信道，或者指示第一终端和/或第二终端在这个窗口内发送旁链路定位参考信号。
旁链路定位参考信号的窗口配置可以包括以下至少之一：

可选的，旁链路定位参考信号的窗口的长度与旁链路定位参考信号的业务(traffic)/信道占用率(Channel Occupancy Ratio，CR)/信道繁忙率(Channel Busy Ratio，CBR)/优先级(Priority)相关。可以预定义/预配置/配置旁链路定位参考信号的窗口的长度与SL PRS traffic/CR/CBR/Priority的对应关系。终端根据该对应关系，结合待传输的信息，如旁链路定位参考信号、旁链路定位测量上报确定窗口长度。
其中，窗口配置可以结合资源池信息。比如窗口起始位置、长度或周期等配置与资源池的逻辑时隙有关。
(12)旁链路定位参考信号所在的频域位置，如物理资源块级别(PRB level)、子信道级别(subchannel level)、资源粒子(Resource Element，RE)级别(RE level)的频域位置，或者旁链路定位参考信号资源块的频域位置。该频域位置可以基于旁链路定位参考信号所在的资源池确定。
如果旁链路定位参考信号占用的时隙为一个，或者旁链路定位参考信号占用的时隙为多个且频域位置相同，或者指示旁链路定位参考信号的起始频域位置，则旁链路定位参考信号所在的频域位置可以包括起始频域位置和/或带宽。可选的，起始频域位置和/或带宽可以通过联合编码的方式确定。可选的，起始频域位置和/或带宽的粒度可以为子信道(subchannel)或M个子信道(subchannel)。可选的，起始频域位置和/或带宽等配置可以是基于旁链路定位参考信号的资源池进行的。
如果旁链路定位参考信号占用的时隙为多个，且频域位置不完全相同，则旁链路定位参考信号所在的频域位置可以包括旁链路定位参考信号时隙的起始频域位置以及频率资源指示值(Frequency resource indication value，FRIV)，和/或，包括每个旁链路定位参考信号的起始频域位置和/或带宽。
其中，该频域位置可以基于旁链路定位参考信号所在资源池计算，比如频域位置基于资源池的子信道配置，基于资源池频域起始位置计算。只有获得了旁链路定位参考信号资源池信息，才能获得旁链路定位参考信号所在的频域位置。
(13)旁链路定位参考信号的梳状结构大小和/或梳状结构偏移，即SL PRS的comb size和/或comb offset。可选的，comb offset可以为旁链路定位参考信号在时隙内第一个符号的资源粒子偏移(RE offset)。可选的，comb大小可以由网络配置或预配置或协议约定多个，终端选择并指示其中一个。可选的，comb offset可以由网络配置或预配置或协议约定多个，终端选择并指示其中一个。
(14)旁链路定位参考信号的循环移位(cyclic shift)。可选的，循环移位可以由网络配置或预配置或协议约定多个，终端选择并指示其中一个。
需要说明的是，上述(10)、(13)、(14)提到的时隙内符号位置、梳状结构、循环移位等配置可以基于资源池信息获得。比如：循环移位信息在资源池中预配置多个，只有接收终端明确了旁链路定位参考信号所在的资源池后，才能通过第一信息指示准确获得循环移位值。
(15)旁链路定位参考信号的资源池内，旁链路定位参考信号关联的物理旁链路控制信道的时频位置，具体可以参考旁链路定位参考信号的时隙和频域位置的指示方式。该时频位置可以基于旁链路定位参考信号所在的资源池确定。
可选的，预配置物理旁链路控制信道和旁链路定位参考信号的关联关系，终端确定旁链路控制信道配置或旁链路定位参考信号配置后，可以相应确定关联的旁链 路定位参考信号配置信息或旁链路控制信道配置信息。

其中，μPRS为旁链路定位参考信号对应的SCS或numerology，μindicator为第一信息对应的SCS或numerology，为旁链路定位参考信号与第一信息关联的定时非同步时的定时偏移。
