具体实施方式
在下文中将结合附图对本发明的示范性实施例进行描述。为了清楚和简明起见，在说明书中并未描述实际实施方式的所有特征。然而，应该了解，在开发任何这种实际实施例的过程中必须做出很多特定于实施方式的决定，以便实现开发人员的具体目标，例如，符合与系统及业务相关的那些限制条件，并且这些限制条件可能会随着实施方式的不同而有所改变。此外，还应该了解，虽然开发工作有可能是非常复杂和费时的，但对得益于本公开内容的本领域技术人员来说，这种开发工作仅仅是例行的任务。
在此，还需要说明的一点是，为了避免因不必要的细节而模糊了本发明，在附图中仅仅示出了与根据本发明的方案密切相关的设备结构和/或处理步骤，而省略了与本发明关系不大的其他细节。
图1示出了根据本公开的一个实施例的用于无线通信的电子设备100的功能模块框图。
如图1所示，电子设备100包括：确定单元101，其可以通过基于电子设备100与在电子设备100的服务范围内的用户设备之间的连接状态而从多个原始可重构智能表面选出的多个选定可重构智能表面，确定用户设备的初始位置信息。
其中，确定单元101可以由一个或多个处理电路实现，该处理电路例如可以实现为芯片。
电子设备100可以作为无线通信系统中的网络侧设备，具体地例如可以设置在基站侧或者可通信地连接到基站。这里，还应指出，电子设备100可以以芯片级来实现，或者也可以以设备级来实现。例如，电子设备100可以工作为基站本身，并且还可以包括诸如存储器、收发器(未示出)等外部设备。存储器可以用于存储基站实现各种功能需要执行的程序和相关数据信息。收发器可以包括一个或多个通信接口以支持与不同设备(例如，用户设备(UE)、其他基站等等)间的通信，这里不具体限制收发器的实现形式。
作为示例，基站例如可以是eNB或gNB。
根据本公开的无线通信系统可以是5G NR(New Radio，新空口)通信系统。进一步，根据本公开的无线通信系统可以包括非地面网络(Non-terrestrial network，NTN)。可选地，根据本公开的无线通信系统还可以包括地面网络(Terrestrial network，TN)。另外，本领域技术人员可以理解，根据本公开的无线通信系统还可以是4G或3G通信系统。
电子设备100与用户设备之间的连接状态包括：电子设备100与用户设备之间没有建立通信连接的非连接状态和电子设备100与用户设备之间已经建立通信连接的已连接状态。
假设电子设备100与用户设备之间具有M个原始可重构智能表面，这M个原始RIS的序列号(ID)分别为：RIS-1，RIS-2，…，RIS-M。根据电子设备100与用户设备之间的连接状态，从M个原始可重构智能表面中选出N(N是小于等于M的正整数)个选定可重构智能表面，用于确定用户设备的初始位置信息。
在根据本公开的实施例中，通过基于电子设备100与用户设备之间的连接状态而选出的多个选定可重构智能表面来确定用户设备的位置信息，提高了对用户设备进行定位的适用性，以及能够提高定位的覆盖范围。
作为示例，确定单元101可以被配置为在电子设备100与用户设备之间处于非连接状态的情况下，经由多个原始可重构智能表面分别广播包括前导码的下行同步信号，以供用户设备基于前导码选出多个选定可重构智能表面。由此，使得能实现以下益处中至少之一：定位复杂度低、易实现，以及能够提高定位精度并减少定位开销。
由此，在非连接状态下，可以基于前导码来选出多个选定可重构智能表面以用于进行定位。
作为示例，下行同步信号可以包括同步信号块(SSB)。本领域技术人员还可以想到下行同步信号的其他示例，这里不再累述。在下文中，为了简便，以下行同步信号是SSB为例来进行描述。
作为示例，与多个原始可重构智能表面分别对应的下行同步信号不包括共同的前导码。
例如，与RIS-1对应的SSB为SSB1，与RIS-2对应的SSB为SSB2，…，与RIS-M对应的SSB为SSBM。
图2示出了根据本公开实施例的可重构智能表面与下行同步信号之间的映射的一个示例。假设SSB-per-rach-occasion<1，这意味着一个RIS具有多个PRACH时机，RIS被配置有宽波束来广播信号。为了简单，图2中仅示出了4个RIS(其序列号分别为RIS-1、RIS-2、RIS-3、RIS-4)与SSB资源之间的映射。从图2可见，与RIS-1对应的SSB为SSB1、与RIS-2对应的SSB为SSB2、与RIS-3对应的SSB为SSB3、以及与RIS-4对应的SSB为SSB4。以SSB1为例，图2示出的4个SSB1表示SSB1中包括4个前导码，每个前导码所对应的时域和频域资源分别通过横轴和纵轴表示。例如，图2中用椭圆圈起来的SSB1用于示意性地表示SSB1对应的4个前导码时频资源当中的单个前导码时频资源。图2中的SSB2、SSB3、SSB4与SSB1类似地包括4个前导码。本领域技术人员可以理解，每个SSB中包括的前导码的数量可以是除了4之外的其他数量。从图2可见，SSB1、SSB2、SSB3、SSB4均不占用共同的时频资源，从而可以在不同的时频资源上通过PRACH(物理随机接入信道)发送前导码。在这种情况下，可以直接通过PRACH来用于进行定位。
图3示出了根据本公开实施例的电子设备100经由原始可重构智能表面向用户设备广播SSB的一个示例。
为了简单，在下文中，有时用gNB表示电子设备100，以及用UE表示用户设备。
如图3所示，gNB经由RIS-1向UE广播SSB1，……，经由RIS-M向UE广播SSBM。在图3中，每个SSB中不包括共同的前导码。
作为示例，与多个原始可重构智能表面中的每个原始可重构智能表面对应的下行同步信号还包括该原始可重构智能表面的粗波束的序列号。
例如，每个原始可重构智能表面可以分别具有若干个粗波束。在下文中，为了简单，假设每个原始可重构智能表面分别具有3个粗波束，并将这3个粗波束的序列号标记为粗波束1、粗波束2以及粗波束3。本领域技术人员可以理解，每个原始可重构智能表面可以具有其他数量的粗波束。可以利用每个原始可重构智能表面的3个粗波束分别广播与该原始可重构智能表面对应的SSB。为了更清楚地表示在不同粗波束上广播的SSB，可以将与原始可重构智能表面对应的SSB区分为在不同方向的粗波束上广播的SSB。例如，可以将SSB1区分为通过RIS-1的粗波束1广播的SSB1-1、通过RIS-1的粗波束2广播的SSB1-2、以及通过RIS-1的粗波束3广播的SSB1-3。可以将SSB2区分为通过RIS-2的粗波束1广播的SSB2-1、通过RIS-2的粗波束2广播的SSB2-2、以及通过RIS-2的粗波束3广播的SSB2-3，……，可以将SSBM区分为通过RIS-M的粗波束1广播的SSBM-1、通过RIS-M的粗波束2广播的SSBM-2、以及通过RIS-M的粗波束3广播的SSBM-3。
图4示出了根据本公开实施例的电子设备100经由原始可重构智能表面的粗波束向用户设备广播SSB的一个示例。图4中示出了M个原始RIS(RIS-1、RIS-2、……、RIS-M)。其中，图4中用“╳”标注的gNB与UE之间的连线表示gNB与UE之间不存在直通链路(例如，因为gNB与UE之间存在障碍物而没有直通链路)。
如图4所示，gNB经由RIS-1向UE广播SSB1，更具体地，经由RIS-1的3个粗波束分别广播SSB1-1、SSB1-2和SSB1-3；gNB经由RIS-2向UE广播SSB2，更具体地，经由RIS-2的3个粗波束分别广播SSB2-1、SSB2-2和SSB2-3；……；gNB经由RIS-M向UE广播SSBM，更具体地，经由RIS-M的3个粗波束分别广播SSBM-1、SSBM-2和SSBM-3。
作为示例，多个选定可重构智能表面是用户设备基于对所接收的下行同步信号的测量结果而选出的。
例如，所接收的下行同步信号的测量结果包括所接收的下行同步信号的参考信号接收功率(RSRP)、所接收的下行同步信号的信干噪比等。 在下文中，通常以测量结果是RSRP为例来进行描述。
图5是示出根据本公开实施例的用户设备基于对所接收的下行同步信号的测量结果而选出选定可重构智能表面的示意图。
如图5所示，UE计算经由RIS-1、……、RIS-M所接收到的SSB的RSRP，并将与每个RIS对应的最大RSRP进行比较排序，从RIS-1、……、RIS-M当中选择与前N个最大RSRP对应的RIS作为选定可重构智能表面(选定RIS)。例如，在gNB与UE之间存在遮挡物从而gNB与UE之间不存在直通链路的情况下，N是大于等于3的正整数。
作为示例，确定单元101可以被配置为经由多个选定可重构智能表面中的每个选定可重构智能表面，从用户设备接收与该选定可重构智能表面分别对应的前导码。
例如，对于被选择的每一个选定可重构智能表面，用户设备将相应的前导码经由该选定可重构智能表面发送至电子设备100。
作为示例，确定单元101可以被配置为还经由每个选定可重构智能表面，从用户设备接收与该选定可重构智能表面对应的上报信息，其中，与多个选定可重构智能表面中的、要用于向用户设备发送随机接入响应的第一选定可重构智能表面对应的上报信息包括用于指示第一选定可重构智能表面用于发送随机接入响应的反馈标识，以及与多个选定可重构智能表面中的、除了第一选定可重构智能表面之外的其他选定可重构智能表面对应的上报信息分别包括用于指示其他选定可重构智能表面不用于发送随机接入响应的非反馈标识。
例如，第一选定可重构智能表面可以是选定可重构智能表面RIS-1、……、RIS-N当中的、与最大RSRP对应的RIS。
由此，在选定可重构智能表面当中，仅上报反馈标识的第一选定可重构智能表面用于电子设备100与用户设备之间的通信，而上报非反馈标识的其他选定可重构智能表面仅用于辅助定位。因此，减小了电子设备100和用户设备之间用于定位的信令开销，并且减小了定位所需成本。
例如，电子设备100可以经由第一选定可重构智能表面向用户设备发送随机接入响应。
作为示例，与每个选定可重构智能表面对应的上报信息还包括该选 定可重构智能表面的最优粗波束的序列号，以及最优粗波束是该选定可重构智能表面的粗波束当中的、使得用户设备经由该选定可重构智能表面从电子设备接收到的下行同步信号的测量结果最大的粗波束。
作为示例，与第一选定可重构智能表面对应的上报信息还包括有关位置信息的精度要求。
例如，在精度要求较低时，确定初始位置信息即可，而在精度要求较高时，要确定比初始位置信息更精确的增强位置信息。由此可以满足不同用户设备的不同定位精度需求。
图6示出了根据本公开实施例的电子设备100与用户设备之间进行的信令交互的一个示例。在图6中，为了简单，仅示出了三个选定RIS(RIS-1、RIS-2、和RIS-3)，假设第一选定可重构智能表面为RIS-1(例如，在图6中，UE与gNB之间经由RIS-1的链路被标注为“最大RSRP链路”，意味着RIS-1是RIS-1、RIS-2、RIS-3当中的、与最大RSRP对应的RIS)，其他选定可重构智能表面包括RIS-2(例如，在图6中，UE与gNB之间经由RIS-2的链路被标注为“第二大RSRP链路”，意味着RIS-2是RIS-1、RIS-2、RIS-3当中的、与第二大RSRP对应的RIS)和RIS-3(例如，在图6中，UE与gNB之间经由RIS-3的链路被标注为“第三大RSRP链路”，意味着RIS-3是RIS-1、RIS-2、RIS-3当中的、与第三大RSRP对应的RIS)。
如图6所示，gNB经由RIS-1可以从UE接收与SSB1对应的前导码、反馈标识、RIS-1的最优粗波束的序列号以及定位精度要求；gNB经由RIS-2可以从UE接收与SSB2对应的前导码、非反馈标识、以及RIS-2的最优粗波束的序列号；以及gNB经由RIS-3可以从UE接收与SSB3对应的前导码、非反馈标识、以及RIS-3的最优粗波束的序列号。gNB可以经由RS-1向UE发送随机接入响应。
作为示例，确定单元101可以被配置为基于所接收到的与每个选定可重构智能表面分别对应的前导码，计算与每个选定可重构智能表面对应的、从用户设备到电子设备100之间的到达时延，以及基于与每个选定可重构智能表面对应的到达时延，确定初始位置信息。由此，减小了传统定位方法的时延以及同步误差。
如图6所示，gNB基于从UE接收的前导码，可以分别计算(或测 量)与RIS-1、RIS-2、RIS-3对应的、从gNB到UE之间的到达时延，由此确定初始位置信息。
例如，电子设备100基于上述所计算的到达时延，减去提前获得的从每个选定可重构智能表面链路到电子设备100的到达时延，则可以得到从用户设备到每个选定可重构智能表面链路的到达时延，由此可以确定用户设备的初始位置信息。
图7示出了根据本公开实施例的电子设备100基于前导码、经由选定可重构智能表面确定初始位置信息的一个示例。
在下文中，与RIS-1对应的前导码可以表示为Preamble 1，与RIS-2对应的前导码可以表示为Preamble 2，以及与RIS-3对应的前导码可以表示为Preamble 3。假设与RIS-1的最优粗波束对应的SSB为SSB1-3，与RIS-2的最优粗波束对应的SSB为SSB2-3，以及与RIS-3的最优粗波束对应的SSB为SSB3-2。用t1表示与RIS-1对应的、从UE到gNB之间的到达时延(TOA)，用t2表示与RIS-2对应的、从UE到gNB之间的到达时延，以及用t3表示与RIS-3对应的、从UE到gNB之间的到达时延。则RIS-2相对于RIS-1的到达时延差(TDOA)为t2-t1，RIS-3相对于RIS-1的到达时延差为t3-t1。
在图7中，采用基于前导码的到达时间差方法来计算初始位置信息，基于多个RIS之间的信号到达时延差，则可以算出用户设备到不同RIS之间的距离差，再作出以RIS为焦点、距离差为长轴的双曲线，不同双曲线的交点即为用户的初始位置。例如，在图7中，TDOA-1代表以RIS-3和RIS-1为焦点，用户设备到RIS-3和RIS-1之间的到达时延差所对应的距离差为长轴的双曲线，TDOA-2代表以RIS-2和RIS-1为焦点，用户到RIS-2和RIS-1之间的到达时延差所对应的距离差为长轴的双曲线，可以通过TDOA-1双曲线与TDOA-2双曲线的交点来确定用户设备的初始位置。
作为示例，确定单元101可以被配置为还基于每个选定可重构智能表面的最优粗波束的序列号，确定初始位置信息。
例如，在确定初始位置时，以RIS为原点，将RIS的最优粗波束所对应的到达角度作射线，通过与不同RIS对应的多条射线的交点可以确定用户设备的初始位置。
在下文中，以RIS-1为原点、将RIS-1的最优粗波束所对应的到达角度所作的射线表示为L1，以RIS-2为原点、将RIS-2的最优粗波束所对应的到达角度所作的射线表示为L2，以RIS-3为原点、将RIS-3的最优粗波束所对应的到达角度所作的射线表示为L3。
例如，可以作出图7中与SSB-1-3对应的粗波束所对应的到达角度的射线L1，还作出与SSB-2-3及SSB-3-2对应的粗波束所对应的到达角度的射线L2和L3，这三条射线的交点可以用于确定用户设备的初始位置。
例如，将图7中基于到达角所计算出的初始位置与基于到达时延差计算出的初始位置进行结合，可以获得用户的更准确的初始位置。
图8示出了根据本公开实施例的电子设备100基于前导码、经由选定可重构智能表面确定初始位置信息的另一示例。
在图8中，可以采用基于前导码的多站往返时间(RTT)方法来计算初始位置信息。在图8中，三条RTT曲线RTT-1、RTT-2、以及RTT-3分别代表三个可重构智能表面RIS-1、RIS-2以及RIS-3的多站往返时间所对应的曲线。基于用户设备和RIS之间的到达时延，可以算出用户设备到不同RIS的距离，以RIS自身为圆心，距离为半径，即可得到RTT曲线，多条RTT曲线的交点即为用户位置。更具体地，在图8中，RTT-1表示以RIS-1为圆心，RIS-1和用户设备之间的距离为半径所对应的RTT曲线；RTT-2表示以RIS-2为圆心，RIS2和用户设备之间的距离为半径所对应的RTT曲线；RTT-3表示以RIS-3为圆心，RIS3和用户设备之间的距离为半径所对应的RTT曲线。图8中RTT-1曲线与RTT-2曲线、RTT-3曲线的交点即为用户设备的初始位置。
另外，例如，可以作出图8中与SSB-1-3对应的粗波束所对应的到达角度的射线L1，还作出与SSB-2-3及SSB-3-2对应的粗波束所对应的到达角度的射线L2和L3，这三条射线的交点可以用于确定用户设备的初始位置。
例如，将图8中基于到达角所计算出的初始位置与基于RTT计算出的初始位置进行结合，可以获得用户的更准确的初始位置。
作为示例，与多个原始可重构智能表面分别对应的下行同步信号中的至少一部分下行同步信号包括共同的前导码，以及与每个原始可重构 智能表面对应的下行同步信号还包括该原始可重构智能表面的序列号。
图9示出了根据本公开实施例的RIS与下行同步信号之间的映射的另一示例。假设SSB-per-rach-occasion>1，这意味着一个PRACH时机可以具有多个RIS，RIS被配置有宽波束来广播信号。假设与RIS-1对应的SSB为SSB1、与RIS-2对应的SSB为SSB2、与RIS-3对应的SSB为SSB3、以及与RIS-4对应的SSB为SSB4。在图9中，SSB1/2表示RIS-1与RIS-2之间共享前导码时频资源，SSB3/4表示RIS-3与RIS-4之间共享前导码时频资源。如图9中用椭圆圈起来的SSB1/2用于示意性地表示RIS-1与RIS-2之间共享的单个前导码时频资源。如图9的每一列所示的前导码对应于多个RIS。也就是说，与不同RIS对应的SSB占用共同的时频资源，从而包括共同的前导码。由于不能通过前导码来区分RIS，因此，与原始RIS对应的SSB还包括该原始RIS的序列号。
在这种情况下，如果直接使用PRACH来进行定位，则随机接入的碰撞概率会增加。
图10示出了根据本公开实施例的电子设备100经由原始可重构智能表面向用户设备广播SSB的另一示例。
如图10所示，gNB经由RIS-1向UE广播SSB1，……，经由RIS-M向UE广播SSBM。在图10中，除了前导码之外，每个SSB中还包括原始RIS的序列号。
作为示例，与每个原始可重构智能表面对应的下行同步信号还包括该原始可重构智能表面的粗波束的序列号。
图11示出了根据本公开实施例的电子设备100经由原始可重构智能表面的粗波束向用户设备广播SSB的另一示例。图11中示出了M个原始RIS(RIS-1、RIS-2、……、RIS-M)。假设与RIS-1对应的SSB为SSB1，与RIS-2对应的SSB为SSB2，……，与RIS-M对应的SSB为SSBM。其中，图11中用“╳”标注的gNB与UE之间的连线表示gNB与UE之间不存在直通链路。
如图11所示，gNB经由RIS-1向UE广播SSB1，更具体地，经由RIS-1的3个粗波束分别广播SSB1-1、SSB1-2和SSB1-3；gNB经由RIS-2向UE广播SSB2，更具体地，经由RIS-2的3个粗波束分别广播SSB2-1、SSB2-2和SSB2-3；……；gNB经由RIS-M向UE广播SSBM，更具体 地，经由RIS-M的3个粗波束分别广播SSBM-1、SSBM-2和SSBM-3。如图11所示，每个SSB均包括对应原始RIS的序列号。
作为示例，确定单元101可以被配置为经由多个选定可重构智能表面中的、要用于向用户设备发送随机接入响应的第二选定可重构智能表面，从用户设备接收与第二选定可重构智能表面对应的前导码以及上报信息，以及上报信息包括多个选定可重构智能表面的序列号。因此，减小了电子设备100和用户设备之间用于定位的信令开销，并且减小了定位所需成本。
作为示例，多个选定可重构智能表面是用户设备基于对所接收的下行同步信号的测量结果而选出的。具体请参见结合图5进行的说明，这里不再累述。
例如，接收的SSB的参考信号接收功率最大的选定可重构智能表面被选择作为第二选定可重构智能表面，用户设备经由第二选定可重构智能表面，将与第二选定可重构智能表面对应的前导码发送至电子设备100，同时用户设备上报的上报信息包括所有选定可重构智能表面的序列号。
作为示例，上报信息还包括每个选定可重构智能表面的最优粗波束的序列号，以及最优粗波束是该选定可重构智能表面的粗波束当中的、使得用户设备经由该选定可重构智能表面从电子设备接收到的下行同步信号的测量结果最大的粗波束。
作为示例，上报信息还包括有关位置信息的精度要求。
作为示例，确定单元101可以被配置为基于所接收到的前导码，计算与第二选定可重构智能表面对应的、从用户设备到电子设备之间的到达时延；经由第二选定可重构智能表面，向用户设备发送随机接入响应以及为用户设备配置探测参考信号；经由多个选定可重构智能表面中的、除了第二选定可重构智能表面之外的其他选定可重构智能表面，从用户设备分别接收探测参考信号；经由第二选定可重构智能表面，接收用户设备所上报的、用户设备发送探测参考信号的发送时间；基于从用户设备接收到的探测参考信号以及发送时间，计算与其他选定可重构智能表面分别对应的、从用户设备到电子设备之间的到达时延；以及基于与每个选定可重构智能表面对应的到达时延，确定初始位置信息。由此，减 小了传统定位方法的时延以及同步误差。
例如，电子设备100在从用户设备接收到前导码之后，计算前导码的到达时延。电子设备100通过第二选定可重构智能表面发送随机接入响应至用户设备，并为用户设备配置探测参考信号资源。用户设备在收到资源配置信令后，经由除了第二选定可重构智能表面之外的其他选定可重构智能表面向电子设备100发送探测参考信号。另外，用户设备经由第二选定可重构智能表面将探测参考信号的发送时间上报至电子设备100。电子设备100基于上述发送时间计算从用户设备接收的探测参考信号的到达时延。电子设备100基于与每个选定可重构智能表面对应的到达时延，确定初始位置信息。
图12示出了根据本公开实施例的电子设备100与用户设备之间进行的信令交互的另一示例。在图12中，为了简单，仅示出了三个选定RIS(RIS-1、RIS-2、和RIS-3)，假设第二选定可重构智能表面为RIS-1，其他选定可重构智能表面包括RIS-2和RIS-3。
如图12所示，gNB经由RIS-1可以从UE接收与SSB1对应的前导码、选定RIS的序列号RIS-1至RIS-3、RIS-1至RIS-3的最优粗波束的序列号以及定位精度要求。gNB基于所接收到的前导码，计算与RIS-1对应的、从UE到gNB之间的到达时延。然后，gNB通过RIS-1发送随机接入响应至UE，并为UE配置探测参考信号资源。UE在收到资源配置信令后，经由RIS-2和RIS-3分别向gNB发送探测参考信号(例如，用于定位的探测参考信号SRS-Pos)。另外，UE经由RIS-1将探测参考信号的发送时间上报至gNB。gNB基于上述发送时间计算经由RIS-2和RIS-3从UE接收的探测参考信号的到达时延。最后，gNB基于与RIS-1至RIS-3分别对应的到达时延，确定初始位置信息。
图13示出了根据本公开实施例的电子设备100基于前导码和探测参考信号、经由选定可重构智能表面确定初始位置信息的一个示例。
在图13中，采用基于前导码及探测参考信号的到达时间差方法来确定初始位置信息。与RIS-1对应的前导码可以表示为Preamble 1。SRS-Pos2表示与RIS-2对应的探测参考信号，以及SRS-Pos 3表示与RIS-3对应的探测参考信号。图13中的其他附图标记与图7中的类似，此处不再累述。TDOA-1代表以RIS-3和RIS-1为焦点，用户设备到RIS-3和RIS-1 之间的到达时延差所对应的距离差为长轴的双曲线，TDOA-2代表以RIS-2和RIS-1为焦点，用户到RIS-2和RIS-1之间的到达时延差所对应的距离差为长轴的双曲线，可以通过TDOA-1双曲线与TDOA-2双曲线的交点来确定用户设备的初始位置。
作为示例，确定单元101可以被配置为还基于每个选定可重构智能表面的最优粗波束的序列号，确定初始位置信息。
例如，可以作出图13中与SSB-1-3对应的粗波束所对应的到达角度的射线L1，还作出与SSB-2-3及SSB-3-2对应的粗波束所对应的到达角度的射线L2和L3，这三条射线的交点可以用于确定用户设备的初始位置。
