Description

一种定位信息的传输方法和装置 技术领域
本申请涉及无线通信技术领域，尤其涉及一种定位信息的传输方法和装置。
背景技术
目前，无线通信系统中的定位可以基于核心网的定位管理功能网元(location management function，LMF)来实现。基站可以测量用户设备(user equipment，UE)的探测参考信号(sounding reference signal，SRS)的上行相对到达时间(uplink relative time of arrival，UL RTOA)，并上报给LMF。LMF可以选取参考基站，计算各个基站与参考基站之间的参考信号的到达时延差。LMF可以通过多组基站与参考基站之间的到达时延差对UE进行定位。然而，定位精度通常取决于到达时间(time of arrival，TOA)的测量精度，TOA的测量精度受限于参考信号的传输带宽。然而，在5G新无线(new radio，NR)系统中，将会存在大量能力简化(reduced capability，REDCAP)的终端设备。例如物联网终端，可穿戴设备，家庭智慧终端等等。这种REDCAP终端通常没有大量的数据传输要求，为了降低能耗，提升电池续航时间，软硬件的复杂度有限，能够处理的系统传输带宽较小。因此，REDCAP终端的定位精度难以保证。

在一种可能的实现方式中，终端设备可以向网络设备发送切换时间。其中，切换时间是指终端设备基于第一带宽发送参考信号和基于第二带宽发送参考信号之间的切换时间。该切换时间可以包括第一切换时间和/或第二切换时间。其中，第一切换时间是指终端设备从基于第一带宽发送参考信号切换至基于第二带宽发送参考信号的切换时间，第二切换时间是指终端设备基于第二带宽发送参考信号切换至基于第一带宽发送参考信号的切换时间。
基于上述方案，终端设备可以向网络设备上报基于第一带宽发送参考信号和基于第二带宽发送参考信号之间的切换时间，可以使得网络设备根据该切换时间为终端设备确定较为合理的参考信号的发送周期。比如，在切换时间较长时，可以为终端设备确定一个较大的参考信号周期，可以避免终端设备频繁的在第一带宽和第二带宽之间进行切换导致数据传输的效率降低，可以降低终端设备的能耗。

基于上述方案，终端设备可以基于第一带宽发送参考信号，可以提高参考信号的发送带宽，以提高对终端设备的定位精度。
在一种可能的实现方式中，终端设备可以接收来自网络设备的第二参考信号配置信息。其中，第二参考信号配置信息可以用于指示终端设备基于第二带宽发送参考信号。终端设备可以按照第二参考信号配置信息，基于第二带宽发送参考信号。

参阅图3，为本申请实施例提供的定位信息的传输方法的示例性流程图，可以包括以 下步骤。
步骤301：网络设备向终端设备发送第一信息。
这里的终端设备可以通过随机接入过程与网络设备建立上行同步，并通过RRC建立过程与网络设备建立无线资源控制(radio resource control，RRC)连接。由于对于初始接入的终端设备，网络设备没有该终端设备的能力信息。所以，网络设备可以向终端设备发送第一信息，请求终端设备的能力信息。该第一信息可以指示终端设备上报自身的能力信息。其中，该第一信息可以是终端设备能力查询(UE Capability Enquiry)消息，或者也可以是新定义消息。
步骤302：终端设备向网络设备发送第一能力信息。
这里的第一能力信息可以包括终端设备基于第一带宽发送SRS的能力信息。可选的，第一能力信息可以包括发送SRS的频段，SRS的射频带宽，如第一带宽，以及发送SRS的链路支持的子载波间隔。

可选的，终端设备也可以向终端设备发送多种能力信息，多种能力信息可以参照现有技术中的能力信息。举例来说，终端设备可以上传自身的数据传输能力。其中，可以包括数据传输时支持的频段，上下行数据传输带宽以及支持的子载波间隔等信息。本申请实施例只重点描述与定位信息的传输方法相关的能力信息，其他能力信息不再赘述。
其中，终端设备可以在终端设备能力信息(UE Capability Information)消息中携带上报的能力信息。比如，终端设备可以在UE Capability Information中携带第一能力信息、第二能力信息和切换时间中的一个或多个。
基于上述方案，终端设备可以具有基于大带宽发送参考信号的能力，因此SRS的传输带宽也相较于目前的数据传输带宽大，可以提高对终端设备的定位精度。以下，结合附图4A介绍终端设备基于大带宽发射SRS的方法。
参阅图4A，为本申请实施例提供的定位信息传输方法的示例性流程图，可以包括以下步骤。
步骤401：LMF接收定位请求信息。
这里的定位请求信息可以用于请求终端设备的位置信息。其中，该定位请求信息可以是终端设备发送的，或者也可以是想要获取终端设备的位置信息的第三方服务器发起的。该定位请求信息可以是位置服务请求(location service request)消息，或者也可以是新定义消息。
步骤402：LMF向终端设备发送第二信息。
这里的第二信息可以用于请求终端设备的定位能力信息。其中，LMF可以通过长期演进定位协议(long term evolution positioning protocol，LPP)消息向终端设备发送第二信息。 该第二信息可以是LPP请求能力(request capabilities)消息，或者也可以是新定义消息。
步骤403：终端设备向LMF发送第一能力信息、第二能力信息和切换时间中的一种或多种。
其中，终端设备可以向通过LPP消息向LMF反馈自身的定位能力信息。例如，终端设备可以通过LPP提供能力(provide capabilities)消息向LMF反馈自身的定位能力信息。
在一个示例中，如果终端设备仅具有基于第一带宽发送SRS的能力，终端设备可以向LMF发送第一能力信息。可选的，终端设备可以向LMF发送切换时间。如果终端设备仅具有基于第二带宽发送SRS的能力终端设备可以向LMF发送第二能力信息。
如果终端设备同时具有基于第一带宽发送SRS的能力和基于第二带宽发送SRS的能力，终端设备可以向LMF上报第一能力信息和第二能力信息。可选的，终端设备可以向LMF上报切换时间。
另一个示例中，如果终端设备具有基于第一带宽发送SRS的能力以及基于第二带宽发送SRS的能力，终端设备也可以向LMF发送第一能力信息，不上报第二能力信息。可选的，终端设备可以向LMF发送切换时间。如果终端设备仅具有基于第二带宽发送SRS的能力，终端设备可以向LMF发送第二能力信息。
步骤404：LMF向第一网络设备发送第三信息。
第一网络设备可以是正在为终端设备提供服务的网络设备。这里的第三信息可以用于请求第一网络设备上报为终端设备确定的SRS配置信息，或者该第三信息可以用于指示第一网络设备为终端设备确定SRS配置信息。其中，该第三信息可以是NR定位协议(NR positioning protocol annex，NRPPa)的定位信息请求(positioning information request)消息，或者也可以是新定义消息。
可选的，该第三信息中可以包括指示信息。这里的指示信息可以用于指示LMF为第一网络设备推荐的SRS配置信息。比如，指示信息可以用于指示第一网络设备为终端设备确定第二SRS配置信息。其中，第二SRS配置信息用于指示终端设备基于第二带宽发送SRS。或者，指示信息也可以用于指示第一网络设备为终端设备确定第一SRS配置信息。其中，第一SRS配置信息可以用于指示终端设备基于第一带宽发送SRS。或者，指示信息也可以用于指示第一网络设备为终端设备确定第一SRS配置信息和第二SRS配置信息。
在一个示例中，LMF可以根据步骤401中接收到的定位请求信息，确定该定位请求的服务质量(quality of service，QoS)或者时延要求，LMF可以根据定位请求的QoS或时延要求为第一网络设备确定推荐的SRS配置信息。比如，如果定位请求的QoS要求较高，则对于定位精度要求较高，LMF可以为第一网络设备推荐基于第一带宽发送SRS的配置信息。如果定位请求的QoS要求较低，则对于定位精度要求较低，LMF可以为第一网络设备推荐基于第二带宽发送SRS的配置信息。或者，如果定位请求的时延要求较高，则需要LMF反馈终端设备的位置信息的周期较短，LMF可以为第一网络设备推荐基于第二带宽发送SRS的配置信息。如果定位请求的时延要求较低，则不需要LMF反馈终端设备的位置信息的周期较短，LMF反馈终端设备的位置信息周期可以较长，LMF可以为第一网络设备推荐基于第一带宽发送SRS的配置信息。或者，如果定位请求的时延要求较高，且定位请求的QoS要求较高，LMF可以为第一网络设备推荐基于第一带宽和第二带宽发送SRS的配置信息。
另一个示例中，LMF可以基于终端设备的定位能力信息为第一网络设备推荐SRS配 置信息。比如，如果终端设备支持基于第一带宽发送SRS，那么LMF可以为第一网络设备推荐基于第一带宽发送SRS的配置信息。又例如，如果终端设备支持基于第二带宽发送SRS不支持基于第一带宽发送SRS，LMF可以为第一网络设备推荐基于第二带宽发送SRS的配置信息。又例如，如果终端设备支持基于第一带宽发送SRS，终端设备也支持基于第二带宽发送SRS，LMF可以为第一网络设备推荐基于第一带宽发送SRS的配置信息、基于第二带宽发送SRS的配置信息、基于第一带宽和第二带宽发送SRS的配置信息中的一个或多个。
步骤405：第一网络设备向终端设备发送SRS配置信息。
这里的SRS配置信息可以包括第一SRS配置信息和第二SRS配置信息中的至少一个。
在一个示例中，第一网络设备可以根据LMF推荐的SRS配置信息为终端设备确定SRS配置信息。比如，如果指示信息指示为终端设备确定第一SRS配置信息，那么第一网络设备可以为终端设备确定第一SRS配置信息，并向终端设备发送第一SRS配置信息。如果指示信息指示为终端设备确定第二SRS配置信息，那么第一网络设备可以为终端设备确定第二SRS配置信息，并向终端设备发送第二SRS配置信息。如果指示信息用于指示为终端设备确定第一SRS配置信息和第二SRS配置信息，第一网络设备可以为终端设备确定第一SRS配置信息和第二SRS配置信息。
另一个示例中，第一网络设备可以根据终端设备的能力信息为终端设备确定SRS配置信息。比如，如果终端设备支持基于第一带宽发送SRS，第一网络设备可以为终端设备确定第一SRS配置信息，并向终端设备发送第一SRS配置信息。如果终端设备仅支持基于第二带宽发送SRS，第一网络设备可以为终端设备确定第二SRS配置信息，并向终端设备发送第二SRS配置信息。如果终端设备支持基于第一带宽和第二带宽发送SRS，第一网络设备可以为终端设备确定第一SRS配置信息和第二SRS配置信息中的一个或多个，并发送给终端设备。
在一种可能的实现方式中，第一网络设备为终端设备确定的第一SRS配置信息中可以包括周期、带宽、频域间隔(combsize)、偏置和循环移位等信息。第一网络设备为终端设备确定的第二SRS配置信息可以包括周期、带宽、combsize、偏执和循环位移等信息。可选的，如果终端设备上报的切换时间较大，例如大于或等于预设阈值时，第一网络设备确定的第一SRS配置信息中的周期可以较大一些不可以过小，例如可以大于或等于预设周期。主要原因是，如果终端设备在第一带宽和第二带宽之间切换的时间较长时，第一SRS配置信息中的周期设置的较小时，可能会导致终端设备频繁在第一带宽和第二带宽之间切换，会增大终端设备的能耗。
其中，第一SRS配置信息和/或第二SRS配置信息中包括的信息可以参见现有技术，本申请实施例不对第一SRS配置信息和/或第二SRS配置信息中包括的信息进行穷举。应理解，终端设备可以基于第一SRS配置信息和/或第二SRS配置信息，在相应的时频资源和带宽上发送SRS。比如，本申请实施例中终端设备可以根据第一SRS配置信息，基于第一带宽，在相应的时频资源上发送SRS。
第一网络设备可以通过RRC消息将SRS配置信息发送给终端设备。比如，可以通过RRC重配置(RRC reconfiguration)消息，将SRS配置信息发送给终端设备。或者，也可以通过新定义消息将SRS配置信息发送给终端设备。
步骤406：第一网络设备向LMF发送为终端设备确定的SRS配置信息。
其中，第一网络设备可以通过定位信息响应(positioning information response)消息将SRS配置信息发送给LMF。其中，如果第一网络设备为终端设备确定的是第一SRS配置信息，则可以将第一SRS配置信息发送给LMF。如果第一网络设备为终端设备确定的是第二SRS配置信息，则可以将第二SRS配置信息发送给LMF。如果第一网络设备为终端设备确定的第一SRS配置信息和第二SRS配置信息，则可以将第一SRS配置信息和第二SRS配置信息发送给LMF。
应理解，步骤405和步骤406并不指示执行的先后顺序，可以先执行步骤405再执行步骤406，或者先执行步骤406再执行步骤405，或者也可以同时执行步骤405和步骤406，本申请对此不做限定。
步骤407：LMF选择测量网络设备。
这里的测量网络设备可以是步骤405中为终端设备确定SRS配置信息的第一网络设备，或者也可以是其他网络设备。为便于区分，以下将测量网络设备称为第二网络设备。
步骤408：LMF向第二网络设备发送测量请求(measurement request)消息。
这里的measurement request消息中可以包含终端设备的SRS配置信息。其中，SRS配置信息可以包括第一SRS配置信息和第二SRS配置信息中的一个或多个。
步骤409：终端设备发送SRS。
其中，如果步骤405中终端设备接收到来自第一网络设备的第一SRS配置信息，则终端设备可以基于第一带宽发送SRS。如果步骤405中终端设备接收到来自第一网络设备的第二SRS配置信息，则终端设备可以基于第二带宽发送SRS。如果步骤405中终端设备接收到来自第一网络设备的第一SRS配置信息和第二SRS配置信息，则终端设备可以分别基于第一带宽和第二带宽发送SRS。应理解，终端设备发送的SRS可以由一个或多个第二网络设备接收，也可以由正在为终端设备提供服务的第一网络设备接收。
步骤410：第二网络设备向LMF发送测量响应(measurement response)消息。
其中，measurement response消息中可以包括第二网络设备基于终端设备发送的SRS进行测量得到的测量结果。该测量结果可以是SRS的参考信号接收功率(reference signal receiving power，RSRP)、参考信号接收质量(reference signal receiving quality，RSRQ)、信号与干扰噪声比(signal to interference plus noise ratio，SINR)、相对到达时间(relative time of arrival，RTOA)，到达时间(time of arrival，TOA)和到达角(angle of arrival，AOA)中的一个或多个。或者，该测量结果也可以是基于SRS的RSRS、RSRQ、SINR、RTOA和AOA中的一个或多个量化得到的数值。
在一种可能的实现方式中，如果第一网络设备为终端设备配置了第一SRS配置信息，则终端设备会基于第一带宽发送SRS，第二网络设备也会基于第一带宽发送的SRS进行测量，得到测量结果。如果第一网络设备为终端设备配置了第二SRS配置信息，则终端设备会基于第二带宽发送SRS，第二网络设备也会基于第二带宽发送的SRS进行测量，得到测量结果。如果第一网络设备为终端设备配置了第一SRS配置信息以及第二SRS配置信息，则终端设备会基于第一带宽发送SRS，以及基于第二带宽发送SRS，第二网络设备也会对基于第一带宽发送的SRS进行测量，以及对基于第二带宽发送的SRS进行测量，分别得到第一带宽的SRS的测量结果和第二带宽的SRS的测量结果。
步骤411：LMF基于第二网络设备上报的测量结果处理得到终端设备的位置信息。
其中，LMF可以采用上行到达角(uplink arrival of arrival，UL-AOA)定位技术，或 者上行到达时间差(uplink time difference of arrival，UL-TDOA)定位技术处理得到终端设备的位置信息。需要说明的是，LMF也可以采用其他的定位技术确定终端设备的位置信息，本申请不做具体限定。
在一种可能的实现方式中，基于第一带宽的SRS的测量信息解算得到的终端设备的位置信息可以作为基于第二带宽的SRS的测量信息进行位置解算时的参考信息。以下，对此进行说明。
举例来说，定位请求的QoS要求较高，且定位请求的时延要求较高。因此，可以为终端设备确定基于第一带宽发送SRS的第一SRS配置信息，以及基于第二带宽发送SRS的第二SRS配置信息。其中，第一SRS配置信息中发送SRS的周期为200ms，第二SRS配置信息中发送SRS的周期可以为20ms。终端设备可以按照第一SRS配置信息中的SRS发送周期，基于第一带宽发送SRS，以及按照第二SRS配置信息中的SRS发送周期，基于第二带宽发送SRS。LMF可以接收来自第二网络设备的第一带宽的SRS的测量结果和第二带宽的SRS的测量结果。应理解，第二SRS配置信息中的SRS发送周期较短，LMF也可能仅接收到来自第二网络设备的第二带宽的SRS的测量结果。LMF可以基于SRS的测量结果处理得到终端设备的位置信息。
参阅图4B，终端设备基于第一带宽的SRS的测量结果处理得到终端设备的位置信息为P1。终端设备基于第二带宽的SRS的测量结果处理得到终端设备的位置信息为P2。通过图4B可知，P1与P2的位置相差较远，可以认为P2的误差较大。因此，LMF可以以P1为参考信息，在P1的周围对终端设备进行搜索，并在P1的周围通过第二带宽的SRS的测量结果处理得到终端设备的位置信息。其中，在P1的周围对终端设备进行搜索时的搜索范围可以是预先规定的，图4B中以圆形为例进行说明。在实施时，也可以是矩形范围等，本申请不做具体限定。
基于上述方案，P1是基于第一带宽的SRS的测量结果得到的，因此P1的精度比较高。因此，LMF基于第二带宽的SRS的测量结果解算终端设备的位置信息时，可以以精度较高的终端设备的位置信息作为参考，限定搜索范围，提升小带宽SRS的定位精度。此外，由于基于第二带宽发送SRS的周期较短，因此也可以满足定位请求的时延要求。
以下，结合具体实施例对上述定位信息的传输方法进行说明。参阅图5，可以包括以下步骤。

可选的，网络设备可以为终端设备确定多个第三PRS资源配置信息。其中，一个小区标识可以对应一个第三PRS资源配置信息。该第三PRS资源配置信息中也可以包含小区的频点信息。针对一个小区，网络设备可以配置基于第三带宽接收前述一个小区的PRS，或者可以配置基于第四带宽接收前述一个小区的PRS，或者可以配置基于第三带宽和第四带宽接收前述一个小区的PRS。
