Description

获取信号质量信息的方法、设备及系统 技术领域
本申请涉及通信领域,尤其涉及获取信号质量信息的方法、设备及系统。
背景技术
在移动通信系统的切换流程中,如图1所示,源基站在确定目标小区后,向目标小区所属的目标基站发送切换请求;若目标基站允许终端设备接入目标小区,则向源基站发送切换请求确认,其中携带用于接入目标小区的相关信息;之后,源基站向终端设备发送切换命令,其中携带来自目标基站的用于接入目标小区的相关信息;终端设备收到该切换请求后,根据其携带的相关信息对目标小区进行随机接入(random access,RACH)。
目前,源基站主要根据终端设备上报的对其服务小区的相邻小区测量的信号质量信息,确定目标小区,而相邻小区的信号质量信息由终端设备根据相邻小区对应的同步信号(synchronization signal,SS)/物理广播信道(physical broadcast channel,PBCH)块(SSB)等信号测量得到。
然而,若基站不发送其控制的某个小区对应的SSB,则终端设备无法测量得到该小区的信号质量信息,从而导致源基站无法获取该小区的信号质量信息,进而无法根据该小区的信号质量信息控制终端设备进行切换。

在一种可能的设计中,该获取信号质量信息的方法还包括:源网络设备向目标网络设备发送第一消息,该第一消息用于请求将终端设备切换至第一小区;源网络设备接收来自目标网络设备的第二消息,第二消息用于指示允许终端设备切换至第一小区。
基于该方案,一方面,可以使得源网络设备控制终端设备切换至第一小区,从而使得终端设备能够切换至原本不发送SSB的小区;另一方面,在目标网络设备与源网络设备通过有线接口连接的情况下,目标网络设备可以通过该有线接口将第一小区的信号质量信息发送给源网络设备,使得源网络设备进行切换判决,而无需节能小区发送SSB使得终端设备通过无线接口测量后再上报给源网络设备进行切换判决,从而节省空口资源开销。

具体实施方式
为了方便理解本申请实施例的技术方案,首先给出本申请相关技术或名词的简要介绍如下。
第一、下行物理信道:
在新无线(new radio,NR)系统(即通常所说的第五代(5th generation,5G)系统)中,下行物理信道大致分为如下三类:物理广播信道(physical broadcast channel,PBCH),通常用于承载系统广播消息;物理下行控制信道(physical download control channel,PDCCH),通常用于控制信令的传输,例如上下行调度信令、功率控制信令等;物理下行共享信道(physical download shared channel,PDSCH),通常用于承载下行用户数据。
第二、物理信号:
本申请实施例中,主要对以下几种物理信号进行简要介绍:
1、主同步信号(primary synchronization signal,PSS)/辅同步信号(secondary synchronization signal,SSS):主要用于时频同步、初始波束选择、小区信号质量的测量、无线资源管理(radio resource management,RRM)的测量等。
其中,主同步信号/辅同步信号通常称为主/辅同步信号。小区信号质量主要通过SSS测量,小区信号质量信息可以用以下一项或多项来指示:参考信号接收功率
(reference signal received power,RSRP)、参考信号接收质量(reference signal received quality,RSRQ)、参考信号信噪比(reference signal-signal to interference and noise ratio,RS-SINR)。
2、同步信号/物理广播信道块(SS/PBCH block,SSB):由PSS、SSS、和PBCH组合在一起构成。SSB周期发送,在时域上占用4个正交频分复用(orthogonal frequency division multiple,OFDM)符号,按照从0-3升序编号,也就是PSS、SSS、和PBCH 在四个连续的OFDM符号内传输构成SSB;SSB在频域上占用20个资源块(resource block,RB)。
3、主信息块(master information block,MIB):在SSB的PBCH中承载的主要广播信息块,其中包括最主要的系统信息。
4、剩余最小系统信息(remaining minimum system information,RMSI):RMSI可以理解为通常所说的系统信息块(system information block,SIB)1,即SIB1。RMSI是终端设备接入小区的必要系统信息。RMSI周期发送,其发送周期与SSB的周期相同。
第三、小区信号质量信息:
本申请实施例中,小区信号质量信息可以理解为:终端设备接收的来自网络设备的该小区的SSB的信号质量信息;或者,也可以理解为:网络设备的该小区接收的来自终端设备的探测参考信号(sounding reference signal,SRS)的信号质量信息,其中,该小区为该网络设备控制的小区。
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。其中,在本申请的描述中,除非另有说明,“/”表示前后关联的对象是一种“或”的关系,例如,A/B可以表示A或B;本申请中的“和/或”仅仅是一种描述关联对象的关联关系,表示可以存在三种关系,例如,A和/或B,可以表示:单独存在A,同时存在A和B,单独存在B这三种情况,其中A,B可以是单数或者复数。并且,在本申请的描述中,除非另有说明,“多个”是指两个或多于两个。“以下至少一项(个)”或其类似表达,是指的这些项中的任意组合,包括单项(个)或复数项(个)的任意组合。例如,a,b,或c中的至少一项(个),可以表示:a,b,c,a-b,a-c,b-c,或a-b-c,其中a,b,c可以是单个,也可以是多个。另外,为了便于清楚描述本申请实施例的技术方案,在本申请的实施例中,采用了“第一”、“第二”等字样对功能和作用基本相同的相同项或相似项进行区分。本领域技术人员可以理解“第一”、“第二”等字样并不对数量和执行次序进行限定,并且“第一”、“第二”等字样也并不限定一定不同。
本申请实施例的技术方案可以应用于各种通信系统。例如:正交频分多址
(orthogonal frequency-division multiple access,OFDMA)、单载波频分多址(single carrier FDMA,SC-FDMA)、5G通信系统和其它系统等。术语“系统”可以和“网络”相互替换。5G通信系统是正在研究当中的下一代通信系统。其中,5G通信系统包括非独立组网(non-standalone,NSA)的5G移动通信系统,独立组网(standalone,SA)的5G移动通信系统,或者,NSA的5G移动通信系统和SA的5G移动通信系统。此外,通信系统还可以适用于面向未来的通信技术,都适用本申请实施例提供的技术方案。上述适用本申请的通信系统仅是举例说明,适用本申请的通信系统不限于此,在此统一说明,以下不再赘述。

以图2所示的源网络设备20和目标网络设备30进行交互为例,本申请实施例中,源网络设备确定终端设备对应的探测参考信号SRS的配置信息后,向目标网络设备发送该SRS的配置信息。目标网络设备在接收来自源网络设备的该SRS的配置信息后,第一小区根据该SRS的配置信息监测该SRS,并向源网络设备发送第一小区监测到的该SRS的信号质量信息。相应的,源网络设备接收来自目标网络设备的第一小区监测到的该SRS的信号质量信息,其中,第一小区为目标网络设备控制的小区,第一小区为节能小区,节能小区为不发送SSB的小区。
基于该方案,由于源网络设备向目标网络设备发送终端设备对应的SRS的配置信息,可以使得目标网络设备的第一小区监测该SRS,并将第一小区监测到的SRS的信号质量信息发送给源网络设备,从而使得源网络设备获得第一小区监测到的SRS的信号质量信息,进而可以根据第一小区监测到的SRS的信号质量信息进行切换相关处理。
