Description

信息指示、信息接收方法、电子设备和存储介质 技术领域
本申请涉及无线通信技术领域，尤其涉及一种信息指示、信息接收方法、电子设备和存储介质。
背景技术
在边链路(Sidelink)通信系统中，用户设备(User Equipment，UE)之间有业务需要传输时，UE之间的业务不经过网络侧，也即不经过UE与基站之间的蜂窝链路转发，而是直接由数据源UE通过Sidelink传输给目标UE，这种传输方式与相关技术中的蜂窝系统通信模式存在明显区别。边链路通信得到了广泛应用，典型应用包括设备到设备(Device-to-Device，D2D)通信和车联网(Vehicle to Everything，V2X)通信等。对于能够应用Sidelink通信的近距离通信用户来说，Sidelink通信不但节省了无线频谱资源，而且可以降低核心网的传输压力，减少了系统资源占用，增加了蜂窝通信系统的频谱效率，可降低通信时延和网络运营成本。
在Sidelink通信中，发送设备进行信令或数据发送的资源选择，一种资源选择的方式是通过中心节点(如基站)的调度，由中心节点决定设备用于发送信令和/或数据的资源，并通过信令通知给终端。另一种资源选择的方式是基于竞争的资源选择方法，发送设备通过监听资源池范围内资源的使用情况，通过监听结果，在资源池内自主的选择发送信令或数据的资源。
在基于竞争的资源选择方法中，终端会执行感知Sensing和资源选择两个过程，在Sensing过程中，终端通过边链路控制信息(Sidelink Control Information，SCI)的接收获得其他终端的预留资源信息，以及终端获取相关资源的参考信号接收功率(Reference Signal Received Power，RSRP)信息。在资源选择过程中，终端会基于Sensing过程的sensing结果排除一些高干扰的资源。例如，在资源选择窗范围内排除其他终端占用且RSRP高于门限值的资源。在进行资源选择后，终端可以进一步在剩余资源中选择资源，用于数据和信令的发送。
终端在排除其他终端占用且RSRP高于门限值的资源时，对于被其他终端指示为占用资源的RSRP，是通过其他终端更早时间的发送的解调参考信号(Demodulation Reference Signals，DMRS)的测量获得的。目前，Sidelink通信的设计主要针对低频，相关技术中的RSRP测量未考虑波束的影响，在更高频率的Sidelink通信是需要考虑波束特性，一个其他终端前后两个资源上发送的波束未必相同，通过对一个其他终端的前一个时频资源上的RSRP测量结果作为后面时刻的时频资源上的RSRP测量结果未必合适。在一个其他终端前后两个波束不同，无法通过一个其他终端在前一个时频资源上的RSRP测量结果直接推断出该终端在后一个时刻资源的干扰情况。

在一个示例性的实施方式中，以指示波束是否发生变化的信息指示为例，图10是本申请实施例提供的一种信息指示方法的示例图，第一终端发送第一控制信息和第二控制信息。第一控制信息中X个比特域，指示多个时频资源的位置，多个时频资源中的任意两个时频资源，时频位置不同。图10中，时频资源1包含物理边链路控制信道(Physical Sidelink Control Channel，PSCCH)和物理边链路共享信道(Physical Sidelink Shared Channel，PSSCH)。PSCCH信道用于承载第一控制信息，PSSCH信道用于承载第二控制信息和数据信息。图10中，时频资源1范围内的第一控制信息所指示的多个时频资源为时频资源1、时频资源2、时频资源3。第一控制信息所指示的多个时频资源中，时域最早的时频资源称为第一时频资源，其它时频资源称为非第一时频资源。
图10中，时频资源1对应的PSCCH和PSSCH信道，对应的发射波束为波束3。时频资源2和时频资源3对应的PSCCH和PSSCH信道，对应的发射波束为波束2。
图10中，第一终端通过时频资源1中的第二控制信息，指示非第一时频资源的波束是否发生改变。例如，第二控制信息包含多个比特，其中的一个比特用于指示非第一时频资源的波束是否发生改变，比特0表示非第一时频资源的波束未发生改变，比特1表示非第一时频资源的波束发生改变。这里的波束发生改变，是指非第一时频资源的发射波束与第一时频资源的发射波束为不同的发射波束。如果波束未发生改变，则意味着非第一时频资源的发射波束与第一时频资源的发射波束为相同的发射波束。
如图11所示，第二终端为UE3，对于第二终端，在时隙n触发资源选择，在资源选择窗[n+T 1,n+T 2]内选择资源，用于PSCCH和PSSCH的发送。其中，资源选择过程如下：
Step 1:在资源选择窗为[n+T 1,n+T 2]包含多个候选资源，排除被其他UE的第一控制信息指示的时频资源存在重叠，且RSRP大于RSRP门限的资源。
Step 2:通过step1中的资源排除后，第二终端在剩余候选资源中，随机选择一个或多个资源，用于发送第二终端的PSCCH和PSSCH。
本实施例中，
如果满足第一条件，则上述step1中的RSRP为测量RSRP和RSRP补偿值之和；
如果不满足第一条件，则上述step1中的RSRP为测量RSRP；
其中，第一条件是指：第二终端接收的第二控制信息指示非第一资源的波束发生改变。
非第一时频资源相对于第一时频资源波束是否发生变化，是指非第一时频资源包含多个信道，与第一时频资源包含的多个信道，两者之间的波束是否改变。例如，非第一时频资源包含PSCCH信道和PSSCH信道，第一时频资源包含PSCCH信道和PSSCH信道。满足以下任一条件，则称为非第一时频资源相对于所述第一时频资源波束发生变化：
非第一时频资源包含的PSCCH信道，相对第一时频资源包含的PSCCH信道的波束发生变化；
非第一时频资源包含的PSSCH信道，相对第一时频资源包含的PSSCH信道的波束发生变化；
非第一时频资源包含的PSCCH信道和PSSCH信道的波束相同，第一时频资源包含的PSCCH信道和PSSCH信道的波束相同，非第一时频资源包含的PSCCH/PSSCH相对第一时频资源包含的PSCCH/PSSCH的波束发生变化。
或者，非第一时频资源相对于所述第一时频资源波束是否发生变化，是指非第一时频资源包含多个类型的DMRS，与第一时频资源包含的多个类型的DMRS，两者之间的波束是否改变。例如，非第一时频资源包含PSCCH DMRS和PSSCH  DMRS，第一时频资源包含PSCCH DMRS和PSSCH DMRS。满足以下任一条件，则称为非第一时频资源相对于所述第一时频资源波束发生变化：
非第一时频资源包含的PSCCH DMRS，相对第一时频资源包含的PSCCH DMRS的波束发生变化；
非第一时频资源包含的PSSCH DMRS，相对第一时频资源包含的PSSCH DMRS的波束发生变化；
非第一时频资源包含的PSCCH DMRS和PSSCH DMRS的波束相同，第一时频资源包含的PSCCH DMRS和PSSCH DMRS的波束相同，非第一时频资源包含的PSCCH DMRS/PSSCH DMRS相对第一时频资源包含的PSCCH DMRS/PSSCH DMRS的波束发生变化。
另外，对于上述测量RSRP的获得方式，接下来进行举例说明。在图11中，如果时频资源3为时隙[n+T 1,n+T 2]中的1个候选资源，通过时频资源2中的PSCCH DMRS或PSSCH DMRS的测量，并且结合指示的在时频资源3上的波束信息获得时频资源3的测量RSRP。或者，通过时频资源1中的PSCCH DMRS或PSSCH DMRS的测量，并且结合指示的在时频资源3上的波束信息获得时频资源3的测量RSRP。例如，指示的在时频资源3上的波束信息与时频资源1上的波束不同，则确定RSRP补偿值为y，进而得到时频资源3的测量RSRP为时频资源1的测量RSRP加上y。
在一个示例性的实施方式中，以指示第一资源和非第一资源之间是否准共地址的信息指示为例，图12是本申请实施例提供的一种信息指示方法的示例图，参见图12，第一终端发送第一控制信息和第二控制信息。第一控制信息中X个比特域，指示多个时频资源的位置，多个时频资源中的任意两个时频资源，时域位置不同。图12中，时频资源1包含PSCCH信道和PSSCH信道。PSCCH信道用于承载第一控制信息，PSSCH信道用于承载第二控制信息和数据信息。图12中，时频资源1范围内的第一控制信息所指示的多个时频资源为时频资源1、时频资源2、时频资源3。第一控制信息所指示的多个时频资源中，时域最早的时频资源称为第一时频资源，其它时频资源称为非第一时频资源。
图12中，时频资源1对应的PSCCH和PSSCH信道，对应的发射波束为波束3。时频资源2和时频资源3对应的PSCCH和PSSCH信道，对应的发射波束为波束2。
图12中，第一终端通过时频资源1中的第二控制信息，指示非第一时频资源和第一时频资源是否准共址。例如，第二控制信息包含多个比特，其中的一个比特用于指示非第一时频资源是否与第一时频资源准共址，比特0表示非第一时频资源和第一时频资源之间不具有准共址关系，比特1表示非第一时频资源和第一时频资源之间准共址。当指示非第一时频资源和第一时频资源之间准共址，则非第一时频资源和第一时频资源使用相同的发射波束。当指示非第一时频资源和第一时频资源之间不具有准共址关系，则非第一时频资源和第一时频资源使用不同的发射波束。
图12中，时频资源1区域内的第二控制信息，指示非第一时频资源和第一时频资源之间不具有准共址关系。
参见图11，第二终端为UE3，对于第二终端，在时隙n触发资源选择，在资源选择窗[n+T 1，n+T 2]内选择资源，用于PSCCH和PSSCH的发送。其中，资源选择过程如下：
Step 1:在资源选择窗为[n+T 1，n+T 2]包含多个候选资源，排除被其他UE的第一控制信息指示的时频资源存在重叠，且RSRP大于RSRP门限的资源。
Step 2:通过step1中的资源排除后，第二终端在剩余候选资源中，随机选择一个或多个资源，用于发送第二终端的PSCCH和PSSCH。
本实施例中，
如果满足第一条件，则上述step1中的RSRP为测量RSRP和RSRP补偿值之和；
如果不满足第一条件，则上述step1中的RSRP为测量RSRP；
其中，第一条件是指：第二终端接收的第二控制信息指示非第一时频资源与第一时频资源之间无准共址关系；
另外，对于上述测量RSRP的获得方式，接下来进行举例说明。在图11中，如果时频资源3为时隙[n+T 1,n+T 2]中的1个候选资源，则该候选资源通过时频资源2中的PSCCH DMRS或PSSCH DMRS的测量，获得时频资源3的测量RSRP。或者，通过时频资源1中的PSCCH DMRS或PSSCH DMRS的测量，获得时频资源3的测量RSRP。
在一个示例性的实施方式中，以信息指示波束编号为例，图13是本申请实施例提供的一种信息指示方法的示例图，参见图13，第一终端在固定的时频资源位置发送N次S-SSB，且规定这N次SSB的波束编号分别为1～N。
如图13所示，第一终端发送第一控制信息和第二控制信息。第一控制信息中X个比特域，指示多个时频资源的位置，多个时频资源中的任意两个时频资源，时域位置不同。图13中，时频资源1包含PSCCH信道和PSSCH信道。PSCCH信道用于承载第一控制信息，PSSCH信道用于承载第二控制信息和数据信息。图13中，时频资源1范围内的第一控制信息所指示的多个时频资源为时频资源1、时频资源2、时频资源3。第一控制信息所指示的多个时频资源中，时域最早的时频资源称为第一时频资源，其它时频资源称为非第一时频资源。
图13中，时频资源1对应的PSCCH和PSSCH信道，对应的发射波束为波束3。时频资源2和时频资源3对应的PSCCH和PSSCH信道，对应的发射波束为波束2。
图13中，第一终端通过时频资源1中的第二控制信息，指示非第一时频资源的波束编号。例如，第二控制信息包含多个比特，其中的X＝2个比特用于指示非第一时频资源的波束编号。
图13中，时频资源1区域内的第二控制信息，指示非第一时频资源的波束编号为2。
参见图11，第二终端为UE3，对于第二终端，在时隙n触发资源选择，在资源选择窗[n+T 1,n+T 2]内选择资源，用于PSCCH和PSSCH的发送。其中，资源选择过程如下：
Step 1:在资源选择窗为[n+T 1,n+T 2]包含多个候选资源，排除被其他UE的第一控制信息指示的时频资源存在重叠，且测量RSRP大于RSRP门限的资源。
Step 2:通过step1中的资源排除后，第二终端在剩余候选资源中，随机选择一个或多个资源，用于发送第二终端的PSCCH和PSSCH。
对于上述Step 1中的测量RSRP，是通过目标信道S-SSB的DMRS(PSBCH DMRS)的测量获得的，也可以是通过SL-CSI-RS，或PSCCH/PSSCH进行RSRP的测量。在图13中的S-SSB，PSCCH，PSSCH等信道为第一终端发送的。假设 图13中的时频资源2为第二终端的资源选择窗中的候选资源之一。
对于时频资源2这一候选资源，第二终端获得该候选资源的测量RSRP的过程如下：
第二终端通过接收第一终端发送的第一控制信息和第二控制信息，发现时频资源2被第一终端指示为占用，且第一终端的第二控制信息指示时频资源2和时频资源3的波束编号为2。第二终端测量第一终端发送的波束编号为2的S-SSB对应的PSBCH DMRS，通过该测量获得测量RSRP，该测量RSRP作为时频资源2的RSRP。
在一个示例性的实施方式中，以信息指示S-SSB索引为例，图14是本申请实施例提供的一种信息指示方法的示例图，第一终端在固定的时频资源位置发送N次S-SSB，通过S-SSB通知各个S-SSB对应的S-SSB索引，或者规定这N次S-SSB的S-SSB索引分别为1～N。
如图14所示，第一终端发送第一控制信息和第二控制信息。第一控制信息中X个比特域，指示多个时频资源的位置，多个时频资源中的任意两个时频资源，时域位置不同。图14中，时频资源1包含PSCCH信道和PSSCH信道。PSCCH信道用于承载第一控制信息，PSSCH信道用于承载第二控制信息和数据信息。图14中，时频资源1范围内的第一控制信息所指示的多个时频资源为时频资源1、时频资源2、时频资源3。第一控制信息所指示的多个时频资源中，时域最早的时频资源称为第一时频资源，其它时频资源称为非第一时频资源。
图14中，时频资源1对应的PSCCH和PSSCH信道，对应的发射波束为波束3。时频资源2和时频资源3对应的PSCCH和PSSCH信道，对应的发射波束为波束2。
图14中，第一终端通过时频资源1中的第二控制信息，指示非第一时频资源对应的S-SSB索引。例如，第二控制信息包含多个比特，其中的X＝2个比特用于指示非第一时频资源的S-SSB索引。
图14中，时频资源1区域内的第二控制信息，指示非第一时频资源对应的S-SSB索引为2。
如图11所示，第二终端为UE3，对于第二终端，在时隙n触发资源选择，在资源选择窗[n+T 1,n+T 2]内选择资源，用于PSCCH和PSSCH的发送。其中，资源选择过程如下：
Step 1:在资源选择窗为[n+T 1,n+T 2]包含多个候选资源，排除被其他UE的第一控制信息指示的时频资源存在重叠，且测量RSRP大于RSRP门限的资源。
Step 2:通过step1中的资源排除后，第二终端在剩余候选资源中，随机选择一个或多个资源，用于发送第二终端的PSCCH和PSSCH。
对于上述Step 1中的测量RSRP，是通过目标信道S-SSB的DMRS(PSBCH DMRS)的测量获得的。在图14中的S-SSB，PSCCH，PSSCH等信道为第一终端发送的。假设图14中的时频资源2为第二终端的资源选择窗中的候选资源之一。
对于时频资源2这一候选资源，第二终端获得该候选资源的测量RSRP的过程如下：
第二终端通过接收第一终端发送的第一控制信息和第二控制信息，发现时频资源2被第一终端指示为占用，且第一终端的第二控制信息指示时频资源2和时频资源3与索引为2的S-SSB有QCL关系。第二终端通过与时频资源2有准共址关系的S-SSB的DMRS的测量(PSBCH DMRS测量)结果，作为时频资源2的测量RSRP。图14中，第一终端发送的索引为2的S-SSB与时频资源2有准共址关系，因此第二终端对索引为2的S-SSB的DMRS的测量结果，作为时频资源2的测量RSRP。
在一个示例性的实施方式中，以插入独立边链路控制信息进行指示为例，图15是本申请实施例提供的一种信息指示方法的示例图，优化前的方案参见图15，从图中可以看出，第一终端在时频资源1～时频资源3上进行控制信息和数据信息的发送。以及，时频资源1～时频资源3上，第一终端使用的发射波束分别为波束3，波束2，波束2。这种情况下，可以认为时频资源2和时频资源1之间无准共址关系。
对于第二终端测量时频资源2的RSRP的时候，是通过时频资源1上的PSCCH DMRS或PSSCH DMRS的测量，获得时频资源2的测量RSRP。由于时频资源1和时频资源2的发射波束不同，因此实际上时频资源1和时频资源2上的实际RSRP不同。从而，通过时频资源1的RSRP测量，推断出的时频资源2的RSRP并不准确。在这种测量不准确的情况下，第二终端无法准确的判断时频资源2上的真实干扰情况，基于不准确的干扰情况，决定是否使用时频资源2用于第二终端的数据和控制信息的发送，使得通信变得不可靠。
图16是本申请实施例提供的一种信息指示方法的示例图；针对图15的改进方法，参见图16，当第一终端的一个用于数据和信令发送的目标时频资源，无法保证与前一个用于发送数据和控制信息的时频资源之间相同发射波束或准共址时，则在该目标时频资源前面插入新的信道，且限制该新的信道和目标时频资源(或目标时频资源内包含的PSCCH和PSSCH)之间是准共址的。
从而，第二终端可以通过测量该新的信道区域的DMRS，获得目标时频资源的测量RSRP。由于上述新的信息和目标时频资源是准共址的，所以可以保证目标时频资源的测量RSRP是准确的。如图16所示，新的信道包括PSCCH和PSSCH，PSCCH和PSSCH对应的频域资源的数目是固定的，例如固定为1个子信道。
