具体实施方式
如背景技术所述，在直通链路中传输定位参考信号，这对现有的直通链路中参考信号的传输机制提出了新的要求，目前尚无相关方案。
为解决上述问题，本申请实施例提供了一种定位参考信号的发送方法，在本申请实施例的方案中，目标时隙配置有：第一符号和第二符号，所述第一符号用于自动增益控制，所述第二符号用于收发转换；在所述第一符号和第二符号之间的至少部分的符号上发送所述定位参考信号。在本申请实施例的方案中，在第一符号之后发送定位参考信号，终端可以在第一符号上进行自动增益控制，以满足定位参考信号的功率需求，并且在发送定位参考信号之后进行收发转换。采用这样的方案能够实现在直通链路上传输定位参考信号。
为使本申请的上述目的、特征和有益效果能够更为明显易懂，下面结合附图对本申请的具体实施例做详细的说明。
为便于描述，本申请实施例中将用于自动增益控制的符号记为第一符号(或者，称为AGC符号)，以及将用于收发转换的符号记为第二符号(或者，称为GAP符号)。
为便于描述，本申请实施例中将发送定位参考信号的终端记为发送终端(或者称为Tx UE)，以及将接收定位参考信号的终端记为接 收终端(或者，称为Rx UE)。
本申请所称的定位参考信号是指用于定位的参考信号，所述参考信号可以用于定位发送终端，也可以用于定位发送终端以外的其他终端，本实施例对此并不进行限制。
所述定位参考信号可以是已定义的参考信号，例如PRS、SRS，也可以是新定义的参考信号，本实施例对此并不进行限制。
参照图1，图1是本申请实施例中一种定位参考信号的发送方法的流程示意图，图1示出的方法可以由发送终端执行，如图1所示，所述定位参考信号可以包括步骤S11：
步骤S11：在目标时隙的第一符号和第二符号之间的至少部分符号上发送所述定位参考信号，其中，所述第一符号用于自动增益控制，所述第二符号用于收发转换。
在步骤S11的具体实施中，可以先确定目标时隙。在具体实施中，发送终端可以通过资源感知的方式确定传输资源。在直通链路定位场景中，响应于定位需求，发送终端可以触发资源感知，以确定定位参考信号的传输资源。更具体地，发送终端可以根据资源感知的感知结果确定可用的资源，然后从可用的资源中选择定位参考信号的传输资源。其中，响应于定位需求可以是发送终端接收到接收终端发送的定位请求，但并不限于此。
进一步地，所述传输资源包括：时域资源和频域资源，其中，时域资源可以包括：一个或多个目标时隙，所述频域资源可以为以下一项或多项：载波、部分带宽和资源池。本申请实施例对于频域资源及其确定方法并不进行任何限制。
在本申请实施例的方案中，在目标时隙用于传输定位参考信号的情况下，每个目标时隙中第一符号可以为多个，和/或，每个目标时隙中第二符号的数量也可以为多个。
参照图2，图2是现有技术中直通链路的时隙结构的示意图。如 图2所示，现有技术中，直通链路中的时隙结构包括：单个用于自动增益控制(Automatic Gain Control，AGC)的第一符号和单个用于收发转换的第二符号。也即，终端设备用于自动增益控制和收发转换的时长均为单个符号(Symbol)，这是由于目前直通链路的带宽较窄，终端在单个符号提供的时间内就能完成自动增益控制，以及在单个符号提供的时间内就能完成收发转换。
然而在定位场景中，定位参考信号的传输带宽越大，定位精度越高，为了保证定位的精度，未来直通链路需要为定位参考信号提供较大的传输带宽。当传输带宽较大的定位参考信号时，终端在单个符号的时间内可能无法完成自动增益控制，或者在单个符号的时间内可能无法完成收发转换，因此，目前直通链路中参考信号的时隙结构可能无法满足定位参考信号的传输需求。
本申请实施例的方案中，在用于传输定位参考信号的情况下，目标时隙中用于自动增益控制和/或用于收发转换的符号可以为多个，相比于现有的时隙结构，采用本申请实施例的方案能够为终端提供更多的时间进行自动增益控制和/或收发转换，满足带宽较大的定位参考信号的传输需求，从而有利于保证定位精度。
在具体实施中，第一符号的数量和第二符号的数量可以是预配置的。需要说明的是，同一个时隙中，第一符号的数量和第二符号的数量可以是相同的，也可以是不同的，本实施例对此并不进行限制。
进一步地，在本申请实施例的方案中，可以针对不同的频域资源预配置第一符号和第二符号的数量。更具体地，可以采用以下任意一种方式对第一符号的数量和/或第二符号的数量进行预配置：
方式1：预先配置载波级别的第一符号的数量和/或第二符号的数量，其中，针对不同的载波，所述第一符号的数量和/或第二符号的数量可以是不同的。
方式2：预配置部分带宽级别的第一符号的数量和/或第二符号的 数量，其中，针对不同的部分带宽，所述第一符号的数量和/或第二符号的数量可以是不同的。
方式3：预配置资源池级别的第一符号的数量和/或第二符号的数量，其中，针对不同的资源池，第一符号的数量和/或第二符号的数量可以是不同的。
参照图3，图3是本申请实施例中直通链路的一种时隙结构的示意图。如图3所示，时隙可以包括N1个符号，第一符号的数量可以为X1个，以及第二符号的数量可以为Y1个，N1、X1和Y1均可以为大于1的正整数，且N1>X1+Y1，其中，N1、X1和Y1的值均可以是预配置的，X1和Y1的值可以是相等的，也可以是不相等的。
更具体地，单个时隙中第1个符号至第X1个符号为第一符号，第(N1-Y1)个符号至第N1个符号为第二符号。换言之，单个时隙的前X1个符号用于自动增益调整，最后Y1个符号用于收发转换。也即，终端可以在第1个符号至第X1个符号之间的至少部分符号指示的时间内进行自动增益控制，以及在第(N1-Y1)个符号至第N个符号之间的至少部分符号指示的时间内进行收发转换。
例如，可以自第1个符号开始进行自动增益控制，也可以在第1个符号之后的任意一个第一符号开始进行自动增益控制。类似地，可以自第(N1-Y1)个符号开始进行收发转换，也可以自(N1-Y1)个符号之后的任意一个第二符号开始进行收发转换。
进一步地，图3示出的时隙结构中，第(X1+1)个符号至第(N1-Y1-1)个符号可以记为第一其他符号，所述第一其他符号可以用于以下一种或多种传输：物理直通链路控制信道(PysicalSidelink Control Channel，PSCCH)传输、物理直通链路共享信道(PysicalSidelink Share Channel，PSSCH)传输和定位参考信号传输。其中，PSCCH可以用于承载直通链路控制信息(Sidelink Control Information，SCI)，PSSCH可以用于承载直通链路上传输的数据。换言之，所述第一其他符号可以用于以下一种或多种传输：传输SCI、 传输数据和传输定位参考信号。
需要说明的是，本申请实施例中所称的数据(或者直通链路上的数据)是指由PSSCH承载的数据。
在传输定位参考信号的情况下，可以先传输SCI(也即，进行PSSCH传输)，再传输定位参考信号。
需要说明的是，传输SCI的同时也可以一并传输数据(也即，进行PSSCH传输)。也即，SCI和数据可以占用同一个符号进行传输。具体而言，可以采用频分复用的方式进行PSCCH传输和PSSCH传输。
还需要说明的是，传输定位参考信号的同时也可以一并传输数据。也即，直通链路中，数据和定位参考信号可以占用同一个符号进行传输，占用同一个符号传输的数据和定位参考信号的频域资源是不同的。
在本申请的第一个实施例中，在目标时隙用于传输定位参考信号的情况下，目标时隙的结构为图3示出的结构，在目标时隙未用于传输定位参考信号的情况下，目标时隙的结构可以为图2示出的结构。
具体而言，定位参考信号资源池中的时隙结构配置为图3的时隙结构，而数据通信资源池中的时隙结构配置为图1示出的结构。
由此，在目标时隙用于传输定位参考信号的情况下(例如，目标时隙选自定位参考信号资源池)，目标时隙中第一符号的数量为X1个，第二符号的数量为Y1个。更具体地，目标时隙中前X1个符号为第一符号，最后Y1个符号为第二符号，最后一个第一符号和第一个第二符号之间的至少部分符号可以用于传输定位参考信号。
在目标时隙未用于传输定位参考信号(例如，仅用于数据传输)的情况下，第一符号的数量和第二符号的数量均为单个。更具体地，目标时隙的第一个符号为第一符号，最后一个符号为第二符号，位于第一符号和第二符号之间的符号可以用于进行PSCCH传输和PSSCH 传输。
在本申请的第二个实施例中，定位参考信号资源池中的时隙结构和数据通信资源池中的时隙结构均可以配置为图3示出的结构。
在具体实施中，直通链路的传输资源比较紧张，定位参考信号资源池和数据通信资源池至少部分重叠，可以将定位参考信号资源池中的时隙结构和数据通信资源池中的时隙结构均配置为图3示出的结构。采用这样的方案，可以确保用于传输定位参考信号的时隙能够满足定位传输信号的传输需求。
具体而言，在时隙用于传输定位参考信号的情况下，第一符号的数量为X1个，第二符号的数量为Y1个。在时隙未用于传输定位参考信号的情况下，第一符号的数量也为X1个，第二符号的数量也为Y1个。
进一步地，在时隙用于传输定位参考信号的情况下，最后一个第一符号和第一个第二符号之间的一部分符号可以用于PSCCH传输(也即，传输SCI)，另一部分符号可以用于定位参考信号传输；在目标时隙不用于传输定位参考信号的情况下，最后一个第一符号和第一个第二符号之间的符号可以用于PSCCH传输(也即，传输SCI)和PSSCH传输(也即，传输数据)。
在一个具体的例子中，在定位参考信号资源池的频域资源和数据通信资源池的频域资源存在重叠(部分重叠或者完全重叠)的情况下，可以将数据通信资源池的时隙结构也配置为图3示出的结构；在定位参考信号资源池的频域资源和数据通信资源池的频域资源不重叠的情况下，可以将数据通信资源池的时隙结构仍配置为图2示出的结构(也即，第一符号和第二符号的数量均为单个)。采用这样的方案，既可以确保在目标时隙既用于传输定位参考信号又用于传输数据的情况下满足定位参考信号的传输需求，又可以在仅传输数据时避免时域资源浪费。
参照图4，图4是本申请实施例中直通链路的另一种时隙结构的示意图。如图4所示，单个时隙可以包括：第三符号，所述第三符号用于发送SCI，第三符号之后为至少一个第一符号。如图4所示，最后一个第三符号之后的连续多个符号为第一符号。在其他实施例中，最后一个第三符号之后可以仅为单个第一符号。其中，本实施例对于第三符号的数量并不进行限制。
进一步地，第三符号之前为一个第一符号。
更具体地，单个时隙可以包括N2个符号，第1个符号为第一符号，第2个符号至第(M+1)个符号为第三符号，第(M+2)个符号至第(M+2+X2)个符号为第一符号，第(N2-Y2)个符号至第N2个符号为第二符号。其中，第三符号的数量为M个，N2为大于1的正整数，M、X2和Y2均可以为正整数，N2>1+M+X2+Y2。
需要说明的是，N1和N2的值可以是相同的，也可以是不同的；X1和X2的值可以是相同的，也可以是不同的；Y1和Y2的值可以是相同的，也可以是不同的。
采用图4示出的结构，终端可以在第1个符号指示的时间内进行自动增益控制，然后在第2个符号至第(M+1)个符号指示的时间内传输SCI，接收SCI结束后，可以在第(M+2)个符号至第(M+2+X2)个符号指示的时间内再次进行自动增益控制，更具体地，可以在第1个符号的AGC的基础上进一步进行AGC。
进一步地，第(M+2+X2+1)个符号至第(N2-Y2-1)个符号可以记为第二其他符号。所述第二其他符号可以用于以下一种或多种传输：PSSCH传输和定位参考信号传输。也即，数据和定位参考信号可以占用同一个第二其他符号进行传输。
在本申请的第三个实施例中，定位参考信号资源池中的时隙结构和数据通信资源池中的时隙结构均可以预配置为图4示出的结构。
如上文所述，在具体实施中，直通链路的传输资源比较紧张，定 位参考信号资源池和数据通信资源池至少部分重叠，将定位参考信号资源池中的时隙结构和数据通信资源池中的时隙结构均配置为图4示出的结构，可以确保用于传输定位参考信号的时隙能够满足定位传输信号的传输需求。
具体而言，在目标时隙用于传输定位参考信号的情况下，第三符号之后的连续X2个符号为第一符号，最后Y2个符号为第二符号，最后一个第一符号和第一个第二符号之间的符号可以仅用于传输定位参考信号，也可以既用于传输定位参考信号，也可以用于传输数据。在目标时隙未用于传输定位参考信号的情况下(例如，仅用于传输数据)，第三符号之后的连续X2个符号也为第一符号，最后Y2个符号也为第二符号，最后一个第一符号和第一个第二符号之间的符号用于PSSCH传输。
在一个具体的例子中，在定位参考信号资源池的频域资源和数据通信资源池的频域资源存在重叠(部分重叠或者完全重叠)的情况下，可以将数据通信资源池的时隙结构也配置为图4示出的结构；在定位参考信号资源池的频域资源和数据通信资源池的频域资源不重叠的情况下，可以将数据通信资源池的时隙结构仍配置为图2示出的结构。采用这样的方案，既可以确保在既传输定位参考信号又传输数据的情况下满足PRS的传输需求，又可以在仅传输数据时减少时域资源浪费。
在本申请的第四个实施例中，在目标时隙用于传输定位参考信号的情况下，目标时隙的结构为图4示出的结构，在目标时隙未用于传输定位参考信号的情况下，目标时隙的结构可以为图2示出的结构。
在具体实施中，目标时隙是否用于传输定位参考信号可以是由SCI指示的，例如，可以在SCI中配置1比特用于指示目标时隙是否用于传输定位参考信号，所述SCI可以是占用第三符号进行传输的控制信息。
换言之，目标时隙的结构可以是由SCI指示的。如果在第三符号 发送的SCI既用于数据调度，又用于定位参考信号调度，或者仅用于调度定位参考信号，则目标时隙的结构为图4示出的结构。也即，在最后一个第三符号之后插入一个或多个第一符号，且第二符号的数量为多个。如果第三符号发送的SCI仅用于数据调度，则目标时隙的结构为图2示出的结构。也即，在最后一个第三符号之后不插入第一符号，且第二符号的数量为单个。
由此，在SCI指示目标时隙用于发送定位参考信号的情况下，第三符号之后的连续多个符号均为第一符号，多个第一符号之后的至少部分的符号用于发送所述定位参考信息。进一步地，在SCI指示目标时隙不用于发送定位参考信号的情况下，第三符号之后的连续多个符号用于发送直通链路上的数据。
更具体地，在SCI指示目标时隙用于发送定位参考信号的情况下，第(M+2)个符号至第(M+2+X2)个符号为第一符号，第(N2-Y2)个符号至第N2个符号为第二符号，最后一个第一符号和第一个第二符号之间的至少部分符号可以用于传输定位参考信号。更具体地，位于最后一个第一符号和第一个第二符号之间的符号可以仅用于传输定位参考信号，也可以既用于传输定位参考信号，又用于传输数据。
继续参照图1，在直通链路定位的场景下，确定目标时隙之后，在第一符号和第二符号之间的至少部分的符号上向接收终端发送定位参考信号。更具体地，在最后一个第一符号和第一个第二符号之间的至少部分符号上发送定位参考信号。
需要说明的是，本申请实施例中所称的位于第i个符号和第j个符号之间的符号，是指第i+1个符号至第j-1个符号，并不包括第i个符号和第j个符号。其中，i和j均为正整数。
在本申请的其他实施例中，第一符号的数量和/或第二符号的数量可以是根据定位参考信号确定的。例如，可以是根据定位参考信号的带宽确定的。其中，带宽越大，第一符号的数量越多，或者，带宽越大，第二符号的数量越多。
更具体地，可以根据定位参考信号的带宽确定是否在最后一个第三符号之后插入第一符号以及插入的第一符号的数量。采用这样的方案，可以使时隙结构灵活地适应于定位参考信号的传输需求。
参照图5，图5是本申请实施例中一种定位参考信号的接收方法。图5示出的方法可以由接收终端执行，图5示出的接收方法可以包括步骤S51：
步骤S51：在目标时隙的第一符号和第二符号之间的至少部分符号上接收所述定位参考信号，其中，所述第一符号用于自动增益控制，所述第二符号用于收发转换。
在步骤S51的具体实施中，在接收定位参考信号之前，接收终端可以先接收发送终端发送的资源指示信息，所述资源指示信息可以包括所述目标时隙，由此接收终端可以确定所述目标时隙。在具体实施中，资源指示信息可以由SCI承载。
在本发明的一实施例中，目标时隙的结构可以是预配置的，在传输定位参考信号的情况下，预配置的时隙结构可以是图3示出的结构，也可以是图4示出的结构。
在本发明的另一实施例中，目标时隙的结构可以是根据SCI确定的，例如，可以在SCI中配置1比特用于指示目标时隙是否用于传输定位参考信号。
结合图4，接收终端可以在第三符号指示的时间内接收SCI，如果SCI指示目标时隙用于传输定位参考信号，则在最后一个第三符号之后插入X2个第一符号，并且最后Y2个符号为第二符号。也即，如果SCI指示目标时隙用于传输定位参考信号，则采用图4示出的时隙结构，在第三符号之后的连续多个符号上进行AGC，以及在最后多个符号上进行收发转换。
如果SCI指示目标时隙仅用于传输数据，则仍采用现有的时隙结构，也即，无需在最后一个第三符号之后进行自动增益控制，且进行 收发转换的符号仅为单个，在第三符号之后的符号上直接接收PSSCH承载的数据。
进一步地，在直通链路定位场景下，接收终端可以在目标时隙中最后一个第一符号和第一个第二符号之间接收定位参考信号。
