下面以通信设备为基站为例,结合图2对本公开提供的定位方法进行进一步描述。
步骤201,获取基站发送的定位请求,定位请求用于指示第一UE在直接通信链路sidelink接口发送定位信息。
步骤202,根据定位请求,在sidelink接口发送定位信息。
需要说明的是,定位请求相关的内容可以参照本公开其他各实施例的描述,此处不再赘述。

进一步的,UE还可以按照该定位请求中所携带的发送方式、发送所使用的资源、发送时长、和\或发送周期等信息,在sidelink接口发送基站所需要的定位信息。

进一步的,该定位请求中可以携带请求发送的定位导频信号的标识。在一些实施例中,UE获取到的定位请求中的定位导频信号的标识为1,其可以指示UE在sidelink接口上发送标识为1的定位导频信号。
需要说明的是,上述标识1只是举例说明,不能作为对本公开实施例中定位导频信号的标识等的限定。
另外,该定位请求中还可以携带请求发送的定位导频信号的类型。在一些实施例中,可以定义一种或多种可以在sidelink接口上发送的定位导频信号,其中,不同的定位导频信号可以满足不同的应用场景。在一些实施例中,定位导频信号1适用于商业室内场景,定位导频信号2适用于工业部署场景等。基站当前需要工业部署场景,UE获取到的基站发送的定位请求可能为“请求在sidelink接口上发送定位导频信号2”,本公开对此不做限定。
另外,该定位请求还可以携带请求发送的定位导频信号的波束方向。在一些实施例中,UE在sidelink接口上采用波束扫描方式发送定位导频信号,此时UE获取到的基站发送的定位请求,可能为“请求UE只在特定波束或者特定某些波束集合上发送定位导频信号”,从而可以减少定位导频信号的开销,同时也可以减少接收UE监听的波束。

本公开实施例中,通过上述方式,可以节约sidelink接口上发送定位导频信号的开销,同时也可以减少UE监听的sidelink定位导频信号的范围,从而可以提高效率。
另外,通信设备为基站或定位服务器时,定位请求中还可以包括定位信息。
可以理解的是,定位信息可以为UE提前获取并存储的,在一些实施例中,也可以为基站或定位服务器在定位请求中发送给UE的。基站可以通过一条定位请求向UE发送该定位信息,或者也可以通过多条定位请求向UE发送该定位信息,本公开对此不做限定。

另外,该定位请求还可以包括发送时长、发送周期等,本公开对此不做限定。
另外,UE也可以向第一UE发送定位导频信号。
在一些实施例中,UE有sidelink定位需求,UE可以向第一UE发送定位请求信号。进 一步的,UE可以根据所需的定位导频类型和\或配置等,确定具体要发送的定位请求信号,比如请求信号1对应定位导频信号1,UE期望接收定位导频信号1,则UE可以发送请求信号1给第一UE,本公开对此不做限定。
在一些实施例中,UE向第一UE发送“请求在sidelink接口上发送定位导频信号”定位请求。
进一步的,该定位请求可以携带一种或多种信息。在一些实施例中,该定位请求可以携带请求发送的定位导频信号类型,比如此时UE期望收到定位导频信号2,可以请求第一UE在sidelink接口上发送定位导频信号2。
在一些实施例中,该定位请求也可以携带请求发送的定位导频信号的波束方向。在一些实施例中,第一UE在sidelink接口上采用波束扫描方式发送定位导频信号,而UE只能在特定某个或者某些波束上才能监听到第一UE在sidelink上发送的定位导频信号,此时UE可以请求第一UE只在特定波束或者特定某些波束集合上发送定位导频信号,从而可以减少在sidelink上发送定位导频信号的开销,同时也减少UE监听的波束。
在一些实施例中,该定位请求还可以携带发送所使用的资源,比如可以为时域、频域和\或空域等,本公开对此不做限定。
在一些实施例中,该定位请求还可以携带发送时长、发送周期、请求发送的资源索引号等,本公开对此不做限定。
本公开实施例,获取第一UE在sidelink接口发送的指示消息指示消息用于指示第一UE可提供的定位信息,之后可以向第一UE发送定位请求,该定位请求用于指示第一UE在sidelink接口发送定位信息。由此,节省了UE中sidelink接口资源,极大地提高了在sidelink接口上进行定位的效率。
