具体实施方式
下面将结合本申请实施例中的附图，对本申请实施例中的技术方案进行清楚描述，显然，所描述的实施例是本申请一部分实施例，而不是全部的实施例。基于本申请中的实施例，本领域普通技术人员所获得的所有其他实施例，都属于本申请保护的范围。
本申请的说明书和权利要求书中的术语“第一”、“第二”等是用于区别类似的对象，而不用于描述特定的顺序或先后次序。应该理解这样使用的术语在适当情况下可以互换，以便本申请的实施例能够以除了在这里图示或描述的那些以外的顺序实施，且“第一”、“第二”所区别的对象通常为一类，并不限定对象的个数，例如第一对象可以是一个，也 可以是多个。此外，说明书以及权利要求中“和/或”表示所连接对象的至少其中之一，字符“/”一般表示前后关联对象是一种“或”的关系。
值得指出的是，本申请实施例所描述的技术不限于长期演进型(Long Term Evolution，LTE)/LTE的演进(LTE-Advanced，LTE-A)***，还可用于其他无线通信***，诸如码分多址(Code Division Multiple Access，CDMA)、时分多址(Time Division Multiple Access，TDMA)、频分多址(Frequency Division Multiple Access，FDMA)、正交频分多址(Orthogonal Frequency Division Multiple Access，OFDMA)、单载波频分多址(Single-carrier Frequency Division Multiple Access，SC-FDMA)和其他***。本申请实施例中的术语“***”和“网络”常被可互换地使用，所描述的技术既可用于以上提及的***和无线电技术，也可用于其他***和无线电技术。以下描述出于示例目的描述了新空口(New Radio，NR)***，并且在以下大部分描述中使用NR术语，但是这些技术也可应用于NR***应用以外的应用，如第6代(6th Generation，6G)通信***。
图1示出本申请实施例可应用的一种无线通信***的框图。无线通信***包括终端11和网络侧设备12。其中，终端11可以是手机、平板电脑(Tablet Personal Computer)、膝上型电脑(Laptop Computer)或称为笔记本电脑、个人数字助理(Personal Digital Assistant，PDA)、掌上电脑、上网本、超级移动个人计算机(ultra-mobile personal computer，UMPC)、移动上网装置(Mobile Internet Device，MID)、增强现实(augmented reality，AR)/虚拟现实(virtual reality，VR)设备、机器人、可穿戴式设备(Wearable Device)、车载设备(Vehicle User Equipment，VUE)、行人终端(Pedestrian User Equipment，PUE)、智能家居(具有无线通信功能的家居设备，如冰箱、电视、洗衣机或者家具等)、游戏机、个人计算机(personal computer，PC)、柜员机或者自助机等终端侧设备，可穿戴式设备包括：智能手表、智能手环、智能耳机、智能眼镜、智能首饰(智能手镯、智能手链、智能戒指、智能项链、智能脚镯、智能脚链等)、智能腕带、智能服装等。需要说明的是，在本申请实施例并不限定终端11的具体类型。网络侧设备12可以包括接入网设备或核心网设备，其中，接入网设备也可以称为无线接入网设备、无线接入网(Radio Access Network,RAN)、无线接入网功能或无线接入网单元。接入网设备可以包括基站、无线局域网(Wireless Local Area Networks，WLAN)接入点或WiFi节点等，基站可被称为节点B、演进节点B(eNB)、接入点、基收发机站(Base Transceiver Station，BTS)、无线电基站、无线电收发机、基本服务集(Basic Service Set，BSS)、扩展服务集(Extended Service Set，ESS)、家用B节点、家用演进型B节点、发送接收点(Transmitting Receiving Point，TRP)或所述领域中其他某个合适的术语，只要达到相同的技术效果，所述基站不限于特定技术词汇，需要说明的是，在本申请实施例中仅以NR***中的基站为例进行介绍，并不限定基站的具体类型。
由于在inactive状态下，PRS相对于其他的下行信号和/或信道，优先级是最低的。当调度下行信号和/或信道的DCI距离PRS太近时，UE可能无法快速解码DCI。这种情况下有两种解决方案，一种是忽略PRS，等着接收下行信号和/或信道，另一种是无线接入 网1(RAN1)在连接(connected)态测量间隔(measurement gap)外测量设计的方案，通过比较DCI与PRS之间的距离以及DCI处理时间。当DCI与PRS之间的距离大于DCI处理时间，此时UE可以接收下行信号和/或信道；当DCI与PRS之间的距离小于DCI处理时间，此时UE在接收PRS之前无法解码DCI，UE可以完成PRS的接收。
对于inactive态，当PRS在初始下行链路部分带宽(initial DownLink Bandwidth Part，initial DL BWP)之外时，UE如果需要接收PRS，需要进行射频重调谐(Radio Frequency retuning，RF retuning)。相关技术定义了具体的值：当定位层(positioning layer)和服务小区(serving cell)都来自于频率范围2(FR2)时，RF retuning time为0.25ms；当positioning layer和serving cell中有一个来自于FR1时，RF retuning time为0.5ms。
另外，相关技术中UE需要在整个时间T(非连续接收(Discontinuous Reception，DRX)周期和PRS周期的最小公倍数)内寻找PRS，缺少了connected state下gap外测量的PRS processing window、gap内测量的measurement gap窗的概念，会导致UE功耗的增加。
下面结合附图，通过一些实施例及其应用场景对本申请实施例提供的PRS接收方法进行详细地说明。
本申请实施例提供一种PRS接收方法，如图2所示，包括：
步骤101：处于非激活inactive态时，终端根据PRS与调度下行控制信息DCI之间的距离T1，确定是否接收所述PRS；
或者，
处于所述inactive态时，所述终端在测量窗内接收所述PRS。
其中，调度DCI包括上行调度DCI和下行调度DCI，本申请实施例以下行调度DCI为例进行说明。
在本申请实施例中，终端在处于非激活态时，根据PRS与调度下行控制信息DCI之间的距离T1，确定是否接收PRS，这样在一些情况下终端可以接收低优先级的PRS，不会忽略PRS，避免了PRS资源的浪费；另外，终端可以仅在测量窗内接收PRS，能够降低终端的功耗。
一些实施例中，所述终端根据PRS与调度下行控制信息DCI之间的距离T1，确定是否接收PRS，包括：
所述终端根据所述T1与DCI处理时间T2的关系，确定是否接收所述PRS；
或者，
所述终端根据所述T2和射频重调谐时间T3之和与所述T1的关系，确定是否接收所述PRS。
一些实施例中，所述终端根据所述T1与DCI处理时间T2的关系，确定是否接收所述PRS，包括以下至少一项：
当所述PRS位于初始initial带宽部分BWP内时，若所述T1大于所述T2，则所述终端根据所述调度DCI进行调度传输而不接收所述PRS；否则，所述终端接收所述PRS而 不进行调度传输。例如，当所述PRS位于initial BWP内时，若所述T1不大于所述T2，则终端接收所述PRS而不进行调度传输。
本申请实施例中，当PRS在initial BWP内时，如果PRS与调度下行信号和/或信道的DCI之间的距离T1大于DCI处理时间T2，说明UE可以来得及接收被调度的下行信号和/或信道，即使UE接收了被调度的下行信号和/或信道，也不影响PRS的接收，UE被要求接收被调度的下行信号和/或信道；否则，UE不被要求接收被调度的下行信号和/或信道，UE可以接收PRS，以免造成PRS资源的浪费。例如，当PRS在initial BWP内时，如果PRS与调度下行信号和/或信道的DCI之间的距离T1不大于DCI处理时间T2，说明UE来不及接收被调度的下行信号和/或信道，这时UE不被要求接收被调度的下行信号和/或信道，UE可以接收PRS，以免造成PRS资源的浪费。
一些实施例中，所述终端根据所述T2和射频重调谐时间T3之和与所述T1的关系，确定是否接收所述PRS，包括以下至少一项：
当所述PRS位于initial BWP外时，若所述T1大于所述T2与所述T3的和，且所述调度DCI所调度的传输与所述PRS不碰撞，则所述终端接收所述PRS而不进行调度传输；否则，所述终端根据所述调度DCI进行调度传输而不接收所述PRS。例如，当所述PRS位于initial BWP外时，若所述T1不大于所述T2与所述T3的和，和/或，所述调度DCI所调度的传输与所述PRS碰撞时，终端根据所述调度DCI进行调度传输而不接收所述PRS。
当PRS在initial BWP外时，需要比较PRS与调度下行信号和/或信道的DCI之前的距离T1、DCI处理时间T2以及RF retuning time T3之间的相对关系。当T1大于T2与T3的和时，并且被调度的下行信号和/或信道与PRS不碰撞时，UE不被要求接收被调度的下行信号和/或信道，可以接收PRS，以免造成PRS资源的浪费；否则，UE被要求接收被调度的下行信号和/或信道。例如，当PRS在initial BWP外时，所述T1不大于所述T2与所述T3的和，和/或，所述调度DCI所调度的传输与所述PRS碰撞，这时UE被要求接收被调度的下行信号和/或信道。
一些实施例中，T2由以下至少一项确定：
所述终端的能力；
网络侧设备配置的第一值；
协议约定的第二值。
一些实施例中，T3由定位层和服务小区所属的频率范围确定。
一具体示例中，如图3所示，在inactive态，当PRS在initial BWP之内时，当PRS与调度下行信号和/或信道的DCI之间的距离T1大于DCI处理时间(即DCI解码时间)，UE被要求接收被调度的下行信号和/或信道。
如图4所示，在inactive态，当PRS在initial BWP之内时，当PRS与调度下行信号和/或信道的DCI之间的距离T1小于DCI处理时间(即DCI解码时间)，UE不被要求接收被调度的下行信号和/或信道，UE可以接收PRS。
如图5所示，在inactive态，当PRS在initial BWP之外时，当PRS与调度下行信号和/或信道的DCI之间的距离T1大于DCI处理时间(即DCI解码时间)与RF retuning时间的和，并且被调度的下行信号和/或信道与PRS不碰撞时，UE不被要求接收被调度的下行信号和/或信道，可以接收PRS。
本实施例中，在inactive态下，根据调度下行信号和/或信道的DCI与PRS的距离，DCI处理时间以及RF retuning时间之间的大小相对关系，明确了终端可以接收PRS的条件，避免了PRS资源的浪费。
另外，本申请实施例在inactive state引入测量窗的概念，UE只被要求在测量窗内进行PRS的接收，这样可以降低UE的功耗。
一些实施例中，所述测量窗的周期所包含的所述测量窗的数目大于或等于1，比如测量窗的数目可以为1、或者2、或者更多。
一些实施例中，所述测量窗的周期所包含的所述测量窗的数目等于2的情况下，如图6所示，第一个测量窗的起始时间点为Y1-(X1+P1)，Y1为寻呼时机(paging occasion)的起始时间点，X1为所述第一个测量窗的持续时间，P1为所述终端的寻呼前准备时间；
第二个测量窗的起始时间点Y2为寻呼时机的结束时间点。
一些实施例中，所述测量窗的周期所包含的所述测量窗的数目等于1的情况下，如图7所示，所述测量窗的起始时间点为Y1-(X2+P1)，Y1为寻呼时机的起始时间点，X2为所述测量窗的持续时间，P1为所述终端的寻呼前准备时间；或
所述测量窗的起始时间点为寻呼时机的结束时间点。
其中，所述测量窗的周期可以为PRS周期和寻呼时机周期的最小公倍数，所述测量窗的持续时间为可利用的PRS持续时间。
本实施例中，所述测量窗的持续时间X1或X2为所述终端确定或网络侧设备配置或协议约定的；所述终端的寻呼前准备时间为所述终端确定或网络侧设备配置或协议约定的。其中，X1与X2可以相同，也可以不同。
本实施例在inactive态引入了测量窗，明确了测量窗的数目以及不同数目下的测量窗的位置，并明确了测量窗的周期，通过引入测量窗以及将测量窗设置在paging occasion前后，有效地降低了终端的功耗。

一些实施例中，所述接收模块具体用于当所述PRS位于initial BWP外时，若所述T1大于所述T2与所述T3的和，且所述调度DCI所调度的传输与所述PRS不碰撞，则接收所述PRS而不进行调度传输；否则，当所述PRS位于initial BWP外时，若所述T1不大于所述T2与所述T3的和，和/或，所述调度DCI所调度的传输与所述PRS碰撞，根据所述调度DCI进行调度传输而不接收所述PRS。
当PRS在initial BWP外时，需要比较PRS与调度下行信号和/或信道的DCI之前的距离T1、DCI处理时间T2以及RF retuning time T3之间的相对关系。当T1大于T2与T3的和时，并且被调度的下行信号和/或信道与PRS不碰撞时，UE不被要求接收被调度的下行信号和/或信道，可以接收PRS，以免造成PRS资源的浪费；否则，当PRS在initial BWP外时，所述T1不大于所述T2与所述T3的和，和/或，所述调度DCI所调度的传输与所述PRS碰撞，UE被要求接收被调度的下行信号和/或信道。
