Description

测量邻小区的方法和装置 技术领域
本申请涉及通信领域,具体涉及一种测量邻小区的方法和装置。
背景技术
非陆地通信网(non-terrestrial network,NTN)是第五代(5 th generation,5G)移动通信系统的一个通信场景。在NTN中,接收终端设备发送的信号的网络设备不再是固定在地面上的基站,而是位于空中的网络设备,例如,卫星。
卫星的移动速度非常快,导致卫星与位于地面的终端设备之间的距离变化非常快。例如,低地球轨道(low earth orbit,LEO)卫星与终端设备之间的距离的变化速率可达7千米每秒(km/s)。因此,NTN中不同卫星发送的信号到达终端设备的时延的差别较大。
在一些情况下,终端设备需要接收并测量多个NTN小区(例如,卫星)的信号以进行小区选择或小区重选,网络设备可以通过广播通知终端设备进行小区选择或小区重选的相关配置信息。例如,网络设备可以通过广播同步块测量定时配置(SS/PBCH block measurement timing configuration,SMTC)信息通知终端设备接收邻小区的同步块(SS/PBCH block,SSB)的时间窗口等信息。由于NTN中不同卫星发送的信号到达终端设备的时延的差别较大,终端设备需要在较长的时间窗口内尝试接收SSB,从而增大了终端设备的功耗。

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在没有做出创造性劳动前提下所获得的所有其他实施例,都属于本申请保护的范围。
图1是适用于本申请的一种通信系统的示意图。通信系统100包括网络设备110和终端设备120。
网络设备110为位于空中的网络设备,可以是具有无线通信功能的高空平台站(high altitude platform station,HAPS),该HAPS可以是热气球、飞机、卫星或者其它飞行器。以网络设备110为卫星为例,网络设备110可以是LEO卫星、中地球轨道(medium earth orbit,MEO)卫星或者静止地球轨道(geostationary earth orbit,GEO)卫星,其中,LEO卫星和MEG卫星的运行周期与地球的自转周期不同,不能与地球保持相对静止状态,因此,LEO卫星和MEG卫星也可称为非静止地球轨道(none-geostationary earth orbit,NGEO)卫星。
终端设备120可以是移动终端设备,也可以是固定终端设备。例如,终端设备120可以是具有无线通信功能的手持设备、车载设备、可穿戴设备、计算设备或连接到无线调制解调器的其它处理设备,例如,第三代合作伙伴计划(3 rd generation partnership project,3GPP)所定义的用户设备(user equipment,UE),移动台(mobile station,MS),软终端,家庭网关,机顶盒等等。
图1中的双向箭头线表示指网络设备110与终端设备120之间的信号。当网络设备110为卫星时,卫星可以向终端设备120传输下行数据,其中,下行数据可以经过信道编码、调制映射后传输给终端设120。终端设备120也可以向卫星基站传输上行数据,其中,上行数据也可以经过信道编码、调制映射后传输给卫星。本申请对网络设备110与终端设备120之间的通信方式不做限定。
网络设备110所处的位置可以称为空间段,终端设备120所处的位置可以称为用户 段。可选地,通信系统100还可以包括地面段(图1未示出),例如,卫星测控中心、网络控制中心(network control center,NCC)以及各类关口站(gateway)等。
卫星测控中心具有保持、监视和控制卫星的轨道位置和姿态,并管理卫星的星历表等功能。NCC具有处理用户登记、身份确认、计费和其它的网络管理功能。在一些卫星通信系统中,卫星测控中心和NCC是合二为一的。关口站具有呼叫处理、交换以及与地面通信网的接口等功能。地面通信网是地面段的一个组成部分,用于将卫星的数据包通过核心网发送至终端设备120,即,卫星可以直接与终端设备120通信,也可以通过地面段间接与终端设备120通信。地面通信网可以是公共交换电话网(public switched telephone network,PSTN)、公共地面移动网(public land mobile network,PLMN)或其它各种专用网络,不同地面通信网要求关口站具有不同的网关功能。
在一些卫星通信系统中,卫星通信系统的空间段可以是由管理卫星和一个或多个服务卫星组成的多层结构。在多层结构的卫星通信系统的组网中,空间段可以包括一颗或多颗管理卫星以及受管理卫星管理的服务卫星。本申请中提到的卫星不限于是管理卫星或服务卫星。
下面,将详细介绍本申请提供的在NTN中测量邻小区的方法。
如图2所示,方法200包括:
S210,网络设备确定至少一个终端设备的定位能力。
上述至少一个终端设备属于一个小区,该小区可以称为该至少一个网络设备的本小区。除本小区之外的小区可以称为邻小区。本申请中,本小区可以是NTN小区,也可以是非NTN小区,邻小区指的是NTN小区。上述网络设备可以是卫星等非地面网络设备,也可以是地面网络设备。
终端设备的定位能力可以被理解为:终端设备确定自己所处的位置的能力。
例如,终端设备可以通过北斗卫星导航系统或全球定位系统(global positioning system,GPS)确定自己所在位置,也可以通过基站、无线保真(wireless fidelity,Wi-Fi)信号或蓝牙信号确定自己的位置,还可以通过匹配实时街景与街景地图确定自己的位置。本申请对终端设备的定位能力不做限定。
上述几种终端设备的定位能力的示例中,不同的示例所展示的定位能力不同。例如,通常情况下,当终端设备能够正常接收卫星信号和基站信号时,基于卫星的定位能力高于基于基站的定位能力。
当终端设备的定位能力较高时,终端设备可以较为准确地计算出邻小区的信号到达该终端设备的时延,则终端设备可以准确地确定SMTC窗口(即,测量邻小区的时间窗口)的时域位置和时长;当终端设备的定位能力较低时,终端设备不能准确地计算出邻小区的信号到达该终端设备的时延,因此,终端设备不能准确地确定SMTC窗口的时域位置和时长。
基于上述因素,网络设备需要确定终端设备的定位能力,以便于基于不同的情况发送不同的SMTC信息。
终端设备可以能力上报过程中上报自己的定位能力。
例如,终端设备可以上报自己是否支持卫星定位;当终端设备支持卫星定位时,终端设备还可以上报当前卫星信号的强度,以便于网络设备确定终端设备当前的定位能力。可选地,终端设备也可以直接上报当前的定位精度。
网络设备确定终端设备的定位能力后,可以根据预设条件确定该终端设备的定位能力是否满足要求,该预设条件可以是终端设备的定位方式,也可以是终端设备的定位精度。
例如,当预设条件为终端设备需要基于卫星定位系统进行定位时,若终端设备的定位方式为基于基站进行定位,则该终端设备的定位能力不满足要求;若终端设备的定位方式为基于北斗卫星导航系统进行定位,则该终端设备的定位能力满足要求。
又例如,当预设条件为终端设备的定位精度需要达到误差10米以内时,若终端设备的定位精度大于10米,则该终端设备的定位能力不满足要求;若终端设备的定位精度为5米,则该终端设备的定位能力满足要求。
本申请对网络设备确定终端设备的能力是否满足要求的方式不做限定。
根据属于一个小区的至少一个终端设备的定位能力是否满足要求,网络设备有以下几种处理情况。
情况1,至少一个终端设备的定位能力均不满足要求。
网络设备可以发送包含第一起始时刻偏移信息和第一时长信息的SMTC信息。其中,该第一起始时刻偏移信息用于指示:SMTC窗口的起始时域位置相对于该SMTC窗口所处的SMTC周期的起始时域位置的偏移量,其中,SMTC周期的起始时域位置是基于SSB的发送时刻确定的。该第一时长信息用于指示:SMTC窗口的时长。
情况1-1,网络设备针对频点配置SMTC窗口,第一起始时刻偏移信息可以是基于一个待测频点的全部邻小区的信号时延和本小区的信号时延的最小差值确定的。
例如,上述待测频点对应的本小区的信号到达终端设备的时延是4ms,该待测频点对应3个邻小区,该3个邻小区的信号达到终端设备的时延与本小区的信号到达终端设备的时延的差值分别为6ms、11ms和16ms,则第一起始时刻偏移信息指示的偏移量可以是6ms,也可以是小于6ms的其它数值,例如5ms,以避免计算误差等因素导致终端设备漏检邻小区的SSB。
在网络设备针对频点配置SMTC窗口的情况下,第一时长信息可以是基于待测频点对应的全部邻小区的信号的最小时延与最大时延的间隔确定的。
例如,待测频点对应3个邻小区,该3个邻小区的信号达到终端设备的时延分别为10ms、15ms和20ms,其中,最小时延为10ms,最大时延为20ms,则第一时长信息指示的时长可以是该最大时延与该最小时延的差值,即,10ms。可选地,第一时长信息指示的时长也可以大于10ms,以避免计算误差等因素导致终端设备漏检邻小区的SSB。
情况1-2,网络设备针对邻小区配置SMTC窗口,第一起始时刻偏移信息可以是基于一个待测邻小区的信号的时延确定的。
例如,本小区的信号到达终端设备的时延是4ms,本小区附近存在3个待测邻小区,其中一个邻小区的信号到达终端设备的时延与本小区的信号到达终端设备的时延的差值为6ms,则第一起始时刻偏移信息指示的偏移量可以是6ms,也可以是小于6ms的其它数值,例如5ms,以避免计算误差等因素导致终端设备漏检该邻小区的SSB。
在网络设备针对邻小区配置SMTC窗口的情况下,第一时长信息可以是基于待测邻小区的信号的最小时延与最大时延的间隔确定的。
例如,邻小区的信号到达终端设备的最小时延和最大时延分别为10ms和15ms,则第一时长信息指示的时长可以是该最大时延与该最小时延的差值,即,5ms。可选地,第一时长信息指示的时长也可以大于5ms,以避免计算误差等因素导致终端设备漏检邻小区的SSB。
一个频点对应的多个邻小区的卫星通常包含距离较远的卫星,该多个邻小区的信号时延的差值通常大于一个邻小区的信号的最小时延和最大时延的差值,因此,基于邻小区配置SMTC窗口有利于缩短终端设备测量邻小区的时长,从而降低终端设备的功耗。
情况1-3,网络设备针对邻小区组配置SMTC窗口,第一起始时刻偏移信息可以是基于一个待测邻小区组的信号的最小时延确定的。
又例如,本小区的信号到达终端设备的时延为4ms,本小区附近存在4个待测邻小区,分别为邻小区1、邻小区2、邻小区3和邻小区4,其中,该4个邻小区的信号到达终端设备的时延与本小区的信号到达终端设备的时延差分别为6ms(邻小区1)、8ms(邻小区2)、17ms(邻小区3)和21ms(邻小区4),则网络设备可以将时延接近的邻小区分为一组,即,将邻小区1和邻小区2分为一组,以及,将邻小区3和邻小区4分为一组。以第一起始时刻偏移信息对应的邻小区组为包含邻小区1和邻小区2的邻小区组为例,第一起始时刻偏移信息所指示的偏移量可以是6ms,也可以是小于6ms的其它数值,例如5ms,以避免计算误差等因素导致终端设备漏检邻小区的SSB。
在网络设备针对邻小区组配置SMTC窗口的情况下,第一时长信息可以是基于待测邻小区组的信号的最小时延与最大时延的间隔确定的。
例如,本小区附近存在4个待测邻小区,分别为邻小区1、邻小区2、邻小区3和邻小区4,其中,邻小区1的信号到达终端设备的时延为10ms,邻小区2的信号达到终端设备的时延为12ms,邻小区3的信号达到终端设备的时延为21ms,邻小区4的信号达到终端设备的时延为25ms,则网络设备可以将时延接近的邻小区分为一组,即,将邻小区1和邻小区2分为一组,以及,将邻小区3和邻小区4分为一组。以第一时长信息对应的邻小区组为包含邻小区1和邻小区2的邻小区组为例,第一时长信息指示的SMTC窗口的时长可以是2ms,即最小时延10ms与最大时延12ms的差值。可选地,第一时长信息指示的时长也可以大于2ms,以避免计算误差等因素导致终端设备漏检邻小区的SSB。
一个频点对应的多个邻小区的卫星通常包含距离较远的卫星,该多个邻小区的信号时延的差值通常大于一个邻小区组的信号的最小时延和最大时延的差值,因此,基于邻 小区组配置SMTC窗口有利于缩短终端设备测量邻小区的时长,从而降低终端设备的功耗。
情况2,至少一个终端设备的定位能力均满足要求。
网络设备可以发送包含第二起始时刻偏移信息和第二时长信息的SMTC信息。其中,该第二起始时刻偏移信息用于指示:SMTC窗口的起始时域位置相对于该SMTC窗口所处的SMTC周期的起始时域位置的偏移量。该第二时长信息用于指示:SMTC窗口的时长。
网络设备可以根据本小区的信号到达终端设备的时延确定第二起始时刻偏移信息。例如,本小区的信号到达终端设备的时延为2ms,则第二起始时刻偏移信息指示的偏移量可以是2ms,也可以是小区2ms的值。
第二时长信息所指示的时长可以是网络设备基于预设信息(如通信标准)确定的时间。
终端设备可以基于自己的定位能力确定邻小区的信号时延与本小区的信号时延的差值,并基于该差值调整第二起始时刻偏移信息和第二时长信息指示的SMTC窗口。
情况3,至少一个终端设备包含定位能力不满足要求的终端设备和定位能力满足要求的终端设备。
网络设备可以发送包含以下信息的SMTC信息:第一起始时刻偏移信息、第二起始时刻偏移信息、第一时长信息和第二时长信息。其中,第一时长信息指示的时间长度大于第二时长信息指示的时间长度。
定位能力不满足要求的终端设备由于定位精度较低,网络设备基于终端设备的位置计算得到的邻小区信号时延精度也较低,需要配置较长的SMTC窗口以减小漏检SSB的风险;定位能力满足要求的终端设备由于定位精度较高,终端设备基于自身的位置计算得到的邻小区信号时延精度也较高,配置较短的SMTC窗口即可满足检测SSB的需求。因此,网络设备针对不同的终端设备配置长短不同的SMTC窗口能够满足不同终端设备的需求。
上文所述的几种情况均以毫秒作为时间单位,本申请对SMTC窗口的时间长度、时间偏移量以及周期的单位不做限定,例如,SMTC窗口的时间长度和时间偏移量的单位可以是时域符号,SMTC窗口对应的周期的单位可以是时隙。
网络设备根据至少一个终端设备的定位能力确定SMTC信息后,可以通过系统消息发送SMTC信息,该系统消息例如是系统信息块(system information block,SIB)x,x为大于或等于1的整数。
系统消息还可以包含终端设备测量邻小区所需的至少一个频点,以及,该至少一个频点中每个频点对应的邻小区列表。SMTC信息还可以包含指示SMTC周期的信息。
终端设备可以执行下述步骤。
S220,接收SMTC信息。
S230,根据定位能力和SMTC信息确定SMTC窗口。
对于定位能力不满足要求的终端设备,其可以按照SMTC信息中的第一起始时刻偏移信息和第一时长信息所指示的SMTC窗口接收邻小区的SSB。
图3为定位能力不满足要求的终端设备测量邻小区的一种方法。
当前存在一个终端设备和三个NTN小区,该终端设备为UE1,该三个NTN小区分别为小区0、小区1和小区2。这三个小区在相同的时刻发送SSB,UE1驻留在小区0上。小区0发送与频点1或小区1或小区组1关联的SMTC信息,UE1收到该SMTC信息后执行邻小区测量。
若SMTC信息与频点1存在关联关系,则UE1根据该SMTC信息测量频点1对应的全部邻小区。在本示例中,频点1对应的全部邻小区为小区1和小区2。SMTC信息包含第一起始时刻偏移信息,指示的偏移量为D1;SMTC信息还包含第一时长信息,指示的时长L1为小区1的信号时延与小区2的信号时延的差值。UE1根据网络设备配置的D1和L1在对应的SMTC窗口内接收小区1和小区2的SSB。
若SMTC信息与小区1存在关联关系,则UE1根据该SMTC信息测量小区1。SMTC信息包含第一起始时刻偏移信息,指示的偏移量为D1;SMTC信息还包含第一时长信息,指示的时长为L1(该时长是网络设备确定的时长,与小区1的信号时延与小区2的信号时延的差值没有关系)。UE1根据网络设备配置的D1和L1在对应的SMTC窗口内接收小区1的SSB。可选地,网络设备还可以发送与小区2关联的SMTC信息,以便于UE1测量小区2。
若SMTC信息与小区组1存在关联关系,则UE1根据该SMTC信息测量小区组1。在本示例中,小区组1包含的全部邻小区为小区1和小区2。SMTC信息包含第一起始时刻偏移信息,指示的偏移量为D1;SMTC信息还包含第一时长信息,指示的时长L1为小区1的信号时延与小区2的信号时延的差值。UE1根据网络设备配置的D1和L1在对应的SMTC窗口内接收小区1和小区2的SSB。

若SMTC信息与频点1存在关联关系,则UE2根据该SMTC信息测量频点1对应的全部邻小区。在本示例中,频点1对应的全部邻小区为小区1和小区2。SMTC信息包含第二起始时刻偏移信息,指示的偏移量为D0;SMTC信息还可以包含第二时长信息,指示的时长为L1。
UE2基于自身的定位能力确定小区1的信号时延与小区0的信号时延的差值是O1,并且,UE2基于自身的定位能力确定小区2的信号时延与小区0的信号时延的差值是O2, 其中,O1小于O2,则UE2可以将根据O1调整D0,即,将SMTC窗口的起始时刻的偏移量调整为D0+O1。UE2还可以确定SMTC窗口的时长L2为小区1的信号时延与小区2的信号时延的差值。随后,UE2基于自己确定的D0+O1和L2在对应的SMTC窗口内接收小区1和小区2发送的SSB。
若SMTC信息与小区1存在关联关系,则UE2根据该SMTC信息测量小区1。SMTC信息包含第二起始时刻偏移信息,指示的偏移量为D0;SMTC信息还可以包含第二时长信息,指示的时长为L1。
UE2基于自身的定位能力确定小区0的信号时延与小区1的信号时延的差值是O1,则UE2可以将根据O1调整D0,即,将SMTC窗口的起始时刻的偏移量调整为D0+O1。随后,UE2基于自己确定的D0+O1和网络设备配置的L1在对应的SMTC窗口内接收小区1发送的SSB。
若SMTC信息与小区组1存在关联关系,则UE2根据该SMTC信息测量小区组1包含的全部邻小区。在本示例中,小区组1包含的全部邻小区为小区1和小区2。SMTC信息包含第二起始时刻偏移信息,指示的偏移量为D0;SMTC信息还可以包含第二时长信息,指示的时长为L1。
UE2基于自身的定位能力确定小区1的信号时延与小区0的信号时延的差值是O1,并且,UE2基于自身的定位能力确定小区2的信号时延与小区0的信号时延的差值是O2,其中,O1小于O2,则UE2可以将根据O1调整D0,即,将SMTC窗口的起始时刻的偏移量调整为D0+O1。UE2还可以确定SMTC窗口的时长L2为小区1的信号时延与小区2的信号时延的差值。随后,UE2基于自己确定的D0+O1和L2在对应的SMTC窗口内接收小区1和小区2发送的SSB。
图3和图4所描述的示例中,本小区仅存在一种类型的终端设备,因此,网络设备可以发送包含第一起始时刻偏移信息和第一时长信息的SMTC信息,或者,网络设备可以发送包含第二起始时刻偏移信息和第二时长信息的SMTC信息。
下面再结合图5说明定位能力满足要求的终端设备和定位能力不满足要求的终端设备共存的场景。
如图5所示,当前存在两个终端设备和三个NTN小区,该两终端设备为UE1和UE2,该三个NTN小区分别为小区0、小区1和小区2,这三个小区在相同的时刻发送SSB,UE1和UE2均驻留在小区0上。小区0发送与频点1或小区1或小区组1关联的SMTC信息,UE1和UE2收到该SMTC信息后执行邻小区测量。
