Description

一种确定小区的质量信息的方法及装置 技术领域
本申请涉及无线通信技术领域,特别涉及一种确定小区的质量信息的方法及装置。
背景技术
在第五代(the 5 th generation,5G)通信系统中,终端设备可以通过接收同步信号和PBCH块(synchronization signal and PBCH block,SSB)来实现与网络设备的同步,以及获取系统消息等。其中,主同步信号(primary synchronisation signal,PSS)、辅同步信号(secondary synchronisation signal,SSS)和物理广播信道(physical broadcast channel,PBCH)共同构成一个SSB。进一步地,网络设备可以在一个频点上使用不同波束在不同时域位置发送SSB,采用该种方式,由于网络设备在每个时域位置都要打开发射通道,从而导致网络设备的能耗比较大。
为了节省网络设备的能耗,目前引入一种节能方案,即网络设备在频域上通过多个频点发送SSB,从而减少网络设备需要打开发射通道的时间,达到节能的效果。然而,采用该种方式,终端设备如何确定小区的质量信息,仍需进一步的研究。

(1)终端设备:可以是能够接收网络设备调度和指示信息的无线终端设备,无线终端设备可以是指向用户提供语音和/或数据连通性的设备,或具有无线连接功能的手持式设备、或连接到无线调制解调器的其他处理设备。终端设备可以经无线接入网(radio access network,RAN)与一个或多个核心网或者互联网进行通信,终端设备可以是移动终端设备,如移动电话(或称为“蜂窝”电话,手机(mobile phone))、计算机和数据卡,例如,可以是便携式、袖珍式、手持式、计算机内置的或者车载的移动装置,它们与无线接入网交换语言和/或数据。例如,个人通信业务(personal communication service,PCS)电话、无绳电话、会话发起协议(SIP)话机、无线本地环路(wireless local loop,WLL)站、个人数字助理(personal digital assistant,PDA)、平板电脑(Pad)、带无线收发功能的电脑等设备。无线终端设备也可以称为系统、订户单元(subscriber unit)、订户站(subscriber station),移动站(mobile station)、移动台(mobile station,MS)、远程站(remote station)、接入点(access point,AP)、远程终端设备(remote terminal)、接入终端设备(access terminal)、用户终端设备(user terminal)、用户代理(user agent)、用户站(subscriber station,SS)、用户端设备(customer premises equipment,CPE)、终端(terminal)、用户设备(user equipment,UE)、移动终端(mobile terminal,MT)等。终端设备也可以是可穿戴设备以及下一代通信系统,例如,5G通信系统中的终端设备或者未来演进的公共陆地移动网络(public land mobile network,PLMN)中的终端设备等。

(3)本申请实施例中的术语“系统”和“网络”可被互换使用。“至少一个”是指一个或者多个,“多个”是指两个或两个以上。“和/或”,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的情况,其中A,B可以是单数或者复数。字符“/”一般表示前后关联对象是一种“或”的关系。“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和C中的至少一个”包括A,B,C,AB,AC,BC或ABC。以及,除非有特别说明,本申请实施例提及“第一”、“第二”等序数词是用于对多个对象进行区分,不用于限定多个对象的顺序、时序、优先级或者重要程度。
图1为本申请实施例适用的一种网络架构示意图。如图1所示,终端设备130可接入到无线网络,以通过无线网络获取外网(例如因特网)的服务,或者通过无线网络与其它设备通信,如可以与其它终端设备通信。该无线网络包括RAN和核心网(core network,CN),其中,RAN用于将终端设备(比如终端设备1301或终端设备1302)接入到无线网络,CN用于对终端设备进行管理并提供与外网通信的网关。
RAN中可以包括一个或多个RAN设备,比如RAN设备1101、RAN设备1102。
CN中可以包括一个或多个CN设备,比如CN设备120。当图1所示的网络架构适用于5G通信系统时,CN设备120可以为接入和移动性管理功能(access and mobility management function,AMF)实体或用户面功能(user plane function,UPF)实体等。
应理解,图1所示的通信系统中各个设备的数量仅作为示意,本申请实施例并不限于此,实际应用中在通信系统中还可以包括更多的终端设备、更多的RAN设备,还可以包括其它设备。
图2为本申请实施例适用的又一种网络架构示意图。如图2所示,该网络架构包括CN设备、RAN设备和终端设备。其中,RAN设备包括基带装置和射频装置,其中基带装置可以由一个节点实现,也可以由多个节点实现,射频装置可以从基带装置拉远独立实现,也可以集成在基带装置中,或者部分功能独立集成、部分功能集成在基带装置中。例如,在LTE通信系统中,RAN设备包括基带装置和射频装置,其中射频装置可以相对于基带装置拉远布置,例如射频拉远单元(remote radio unit,RRU)是相对于BBU布置的远端无线单元。
RAN设备和终端设备之间的通信遵循一定的协议层结构,例如控制面协议层结构可以包括RRC层、分组数据汇聚层协议(packet data convergence protocol,PDCP)层、无线链路控制(radio link control,RLC)层、媒体接入控制(media access control,MAC)层和物理层等协议层的功能;用户面协议层结构可以包括PDCP层、RLC层、MAC层和物理层等协议层的功能;在一种可能的实现中,PDCP层之上还可以包括业务数据适配(service data adaptation protocol,SDAP)层。
RAN设备可以由一个节点实现RRC、PDCP、RLC和MAC等协议层的功能,或者可以由多个节点实现这些协议层的功能。例如,在一种演进结构中,RAN设备可以包括CU)和DU,多个DU可以由一个CU集中控制。如图2所示,CU和DU可以根据无线网络的协议层划分,例如PDCP层及以上协议层的功能设置在CU,PDCP以下的协议层,例如RLC层和MAC层等的功能设置在DU。
这种协议层的划分仅仅是一种举例,还可以在其它协议层划分,例如在RLC层划分,将RLC层及以上协议层的功能设置在CU,RLC层以下协议层的功能设置在DU;或者,在某个协议层中划分,例如将RLC层的部分功能和RLC层以上的协议层的功能设置在CU,将RLC层的剩余功能和RLC层以下的协议层的功能设置在DU。此外,也可以按其它方式划分,例如按时延划分,将处理时间需要满足时延要求的功能设置在DU,不需要满足该时延要求的功能设置在CU。
此外,射频装置可以独立集成,不放在DU中,也可以集成在DU中,或者部分拉远部分集成在DU中,在此不作任何限制。
图3为本申请实施例适用的又一种网络架构示意图。相对于图2所示的网络架构,图3中还可以将CU的控制面(CP)和用户面(UP)分离,分成不同实体来实现,分别为控制面(control plane,CP)CU实体(即CU-CP实体)和用户面(user plane,UP)CU实体(即CU-UP实体)。
在以上网络架构中,CU产生的信令可以通过DU发送给终端设备,或者终端设备产生的信令可以通过DU发送给CU。DU可以不对该信令进行解析而直接通过协议层封装后透传给终端设备或CU。以下实施例中如果涉及这种信令在DU和终端设备之间的传输,此时,DU对信令的发送或接收包括这种场景。例如,RRC或PDCP层的信令最终会处理为PHY层的信令发送给终端设备,或者,由接收到的PHY层的信令转变而来。在这种架构下,该RRC或PDCP层的信令,即也可以认为是由DU发送的,或者,由DU和射频装载发送的。
上述图1、图2或图3所示意的网络架构可以适用于各种无线接入技术(radio access technology,RAT)的通信系统中,例如可以是4G(或者称为长期演进(long term evolution,LTE))通信系统,也可以是5G(或者称为新无线(new radio,NR))通信系统,也可以是LTE通信系统与5G通信系统之间的过渡系统,该过渡系统也可以称为4.5G通信系统,当然也可以是未来的通信系统。本申请实施例描述的网络架构以及业务场景是为了更加清楚的说明本申请实施例的技术方案,并不构成对于本申请实施例提供的技术方案的限定,本领域普通技术人员可知,随着通信网络架构的演变和新业务场景的出现,本申请实施例提供的技术方案对于类似的技术问题,同样适用。
本申请以下实施例中的装置,根据其实现的功能,可以位于终端设备或网络设备。当采用以上CU-DU的结构时,网络设备可以为CU、或DU、或包括CU和DU的RAN设备。
在图1、图2或图3所示意的网络架构中,终端设备可以通过接收来自网络设备的SSB来实现与网络设备的同步,以及系统消息解调等。此处,将结合图4a至图4g对SSB所涉及的相关技术特征进行描述。
(1)SSB的构成
本申请实施例中,PSS、SSS和PBCH共同构成一个SSB。如图4a所示,在时域上,1个SSB占用4个正交频分复用(orthogonal frequency division multiplexing,OFDM)符号(symbol),为符号0~符号3,在频域上,1个SSB占用20个资源块(resource block,RB)(一个RB包括12个子载波),也就是240个子载波,子载波编号为0~239。PSS位于符号0的中间的127个子载波上,SSS位于符号2的中间的127个子载波上。为了保护PSS和SSS,分别有不同的保护子载波,保护子载波不用于承载信号,在SSS两侧分别留有子载波作为保护子载波,如图4a中的SSS两侧的空白区域就是保护子载波。PBCH占用符号1和符号3的全部子载波,以及占用符号2的全部子载波中除了SSS所占用的子载波之外的剩余的子载波中的一部分子载波(即剩余的子载波中除了保护子载波之外的子载波)。
其中,PSS可以用于传输小区号,SSS可以用于传输小区组号,小区号和小区组号共同决定了5G通信系统中的多个物理小区号(physical cell identity,PCI)。一旦终端设备成功搜索到了PSS和SSS,也就知道了这个5G载波的物理小区号,从而具备了解析SSB中包含的系统消息的能力。
SSB中的系统消息是由PBCH信道携带的,由于这些信息是终端设备接入网络所必须的信息,因此可以称为主消息块(main information block,MIB)。MIB中可以包含系统帧号、初始接入的子载波间隔,以及其它信息。
由于MIB中包含的信息有限,还不足以支持终端设备接入5G小区。因此终端设备还必须再得到一些必备的系统消息,比如系统信息块(system information block,SIB)1。SIB1以160毫秒为周期在物理下行共享信道(physical downlink shared channel,PDSCH)上传输,由于终端设备已在PBCH所携带的MIB中获取到了SIB1传输所使用的参数以及调度它的控制资源分布情况,因此可以接收SIB1。如此,终端设备可获取到接入5G小区所必须的系统消息,后续可以接入5G小区。
(2)SSB的发送机制
5G通信系统中,针对于一个小区(或者说载波),网络设备可以使用一个频点在不同时刻通过不同的波束发送SSB,来完成小区的广播波束覆盖,如图4b所示。
网络设备在一次波束扫描过程中所发送的SSB的集合可以称为一个同步突发集(synchronization signal burst set,SS burst set)。SS burst set的周期相当于一个特定波束对应的SSB的周期,可以被配置为5ms(毫秒)、10ms、20ms、40ms、80ms或160ms等。由于终端设备在进行小区搜索时,不能在某一个频点上等待过长时间,因此默认按照20ms来进行;如果终端设备在某个频点上等待了20ms的时间,一直未发现SSB,则认为这个频点上不存在5G小区,进而可以转到下一个频点再次尝试。
目前,一个SS burst set周期内最多有4个、8个或64个SSB。当载波频段小于等于3GHz时,一个SS burst set周期内最多有4个SSB。其中,每个SS burst set总是位于5ms的时间间隔内。对于SS burst set的示意可参考图4b,图4b以SS burst set的周期是20ms、且以一个SS burst set包括P个SSB为例。
(3)SSB的时频位置
SSB的时域位置可以是协议规定的,协议规定了不同子载波间隔(subcarrier carrier space,SCS)和SSB的时域模式(pattern)之间的关系。参见图4c、图4d、图4e、图4f和图4g,这几个图分别表示了SSB的时域pattern。
图4c表示子载波间隔为15KHz时,一个时隙内包括的SSB的一种时域pattern,可以看到,一个时隙包括2个SSB,图4c中画斜线的方框表示SSB占用的OFDM符号。
图4d表示子载波间隔为30KHz时,一个时隙内包括的SSB的一种时域pattern,可以看到,一个时隙包括2个SSB,图4d中画斜线的方框表示SSB占用的OFDM符号。
图4e表示子载波间隔为30KHz时,一个时隙内包括的SSB的另一种时域pattern,可以看到,一个时隙包括2个SSB,图4e中画斜线的方框表示SSB占用的OFDM符号。
图4f表示子载波间隔为120KHz时,一个时隙内包括的SSB的一种时域pattern,可以看到,一个时隙包括4个SSB,图4f中画斜线的方框表示SSB占用的OFDM符号。
图4g表示子载波间隔为240KHz时,一个时隙内包括的SSB的一种时域pattern,可以看到,一个时隙包括8个SSB,图4g中画斜线的方框表示SSB占用的OFDM符号。
在4G通信系统中,SSB可以位于载波中心,由于5G通信系统的系统带宽较大,比如高频能达到400MHz,远大于4G的系统带宽(最大20MHz),如果像4G通信系统一样把SSB放在载波中心,终端设备在系统带宽的全部频点上来搜索SSB,则会导致终端设备需要的时间较长,而且非常耗电。因此,5G通信系统中不再将SSB放在载波中心,而是放在每个频段中的一些可能位置。进一步地,每个频段可以对应多个频点信息(比如绝对无线频道编号(absolute radio frequency channel number,ARFCN)),每个频点信息可以对应多个可能位置(网络设备会在其中一个可能位置上发送SSB),针对于某一频点信息,终端设备可以按照同步栅格来盲检多个可能位置,进而获得SSB的频域位置。
第三代合作伙伴项目(3rd generation partnership project,3GPP)目前有针对网络设备(即基站)节能的讨论,网络设备节能主要是为了降低能耗,节约开支。一种可能的节能方案为,网络设备将使用一个频点周期发送的SSB,在频域上进行叠加发送(比如频域采用2个频点、时域上发送时间减半)、从而减少在时域上发送的时间,以达到节能的效果。
举例来说,参见图5a所示,网络设备使用一个频点,时域上分8个位置来发送SSB(SSB#0~SSB#7),比如使用频点f1发送SSB#0~SSB#7。采用该种方式,网络设备在每个时域位置上都要打开发射通道,从而导致打开发射通道的时间较长,能耗比较大。参见图5b所示,网络设备使用2个频点,时域上分4个位置来发送SSB(SSB#0~SSB#7),比如使用频点f1发送SSB#0~SSB#3,使用频点f2发送SSB#4~SSB#7。采用该种方式,网络设备在频域上通过多个频点发送SSB,从而能够有效缩短时域上打开发射通道的时间,有效降低能耗。
然而,引入上述节能方案后,可能会产生一些问题,比如可能导致终端设备确定的小区的质量信息不准确(称为问题1),又比如可能导致终端设备确定频域参考点不准确(称为问题2)。本申请实施例将针对这些问题,研究其相应的解决方案。
一、针对于问题1
本申请实施例中,小区的质量信息用于反映小区的质量,小区的质量可以是指终端设备在该小区上与网络设备通信的质量。示例性地,小区的质量信息可以是终端设备通过测 量网络设备在该小区上发送的信号所得到的,小区的质量信息可以包括参考信号接收功率(reference signal receiving power,RSRP)、参考信号接收质量(reference signal receiving quality,RSRQ)和信噪比(signal to interference plus noise ratio,SINR)中的至少一项。
比如,对于RRC空闲(RRC_IDLE)态、RRC非激活(Inactive)态的终端设备来说,可以通过测量网络设备在小区上发送的SSB得到该小区的质量信息。对于RRC连接(RRC_CONNECTED)态的终端设备来说,可以通过测量网络设备在小区上发送的SSB或者信道状态信息参考信号(channel state information-reference signals,CSI-RS)得到该小区的质量信息。本申请实施例中,将主要以终端设备通过测量SSB得到小区的质量信息为例进行描述。
在目前的方案(比如网络设备采用图5a所示意的方式来发送SSB)中,终端设备确定某一小区的质量信息时,可以在该小区关联的频点f1上测量SSB,进而根据SSB的测量值来评估该小区的质量信息。当引入节能方案(比如网络设备采用图5b所示意的方式来发送SSB)后,一个小区可能对应多个频点(比如两个频点),终端设备若仍采用上述方案来确定小区的质量信息,比如根据频点f1上的SSB的测量值来确定小区的质量信息或根据频点f2上的SSB的测量值来确定小区的质量信息,而未综合考虑两个频点上的SSB的测量值,则会导致确定的小区的质量信息不够准确。
基于此,本申请实施例提供一种确定小区的质量信息的方法,用于提高确定小区的质量信息的准确性。
示例性地,本申请实施例提供的方法可以包括:终端设备接收来自第一网络设备的第一信息,第一信息用于指示第一小区关联的第一SSB和第二SSB,第一SSB的频点信息和第二SSB的频点信息不同;进而,终端设备可以根据第一SSB的测量值和第二SSB的测量值确定第一小区的质量信息。其中,第一SSB的频点信息和第二SSB的频点信息不同,可以是指用于发送第一SSB的频点和用于发送第二SSB的频点不同,比如第一SSB是通过第一频点发送的,第二SSB是通过第二频点发送的。
采用该种方式,终端设备根据第一网络设备发送的第一信息获知第一小区关联两个SSB后,可以综合考虑两个SSB的测量值来确定第一小区的质量信息,从而能够有效提高确定小区的质量信息的准确性。
需要说明的是:(1)第一网络设备发送第一信息的方式可以有多种。在一种可能的方式中,第一网络设备可以通过广播的方式发送第一信息,比如第一网络设备通过系统消息发送第一信息(参见下文的实施例一);在又一种可能的方式中,第一网络设备可以通过专用信令向终端设备发送第一信息,比如通过RRC消息向终端设备发送第一信息(参见下文的实施例二)。
(2)终端设备根据第一信息获知第一小区关联第一SSB和第二SSB后,可以分别在第一频点和第二频点上搜索SSB,进而根据第一频点上搜索到的一个或多个SSB的测量值和第二频点上搜索到的一个或多个SSB的测量值来确定第一小区的质量信息。本申请实施例中,是以终端设备根据第一频点上搜索到的一个SSB(即第一SSB)的测量值和第二频点上搜索到的一个SSB(即第二SSB)的测量值来确定第一小区的质量信息为例进行描述的。
比如,以图5b所示意的情形为例,终端设备可以在频点f1上搜索SSB#0~SSB#3,以及在频点f2上搜索SSB#4~SSB#7,进而根据SSB#0~SSB#7的测量值来确定小区的质量 信息。考虑到频点f1对应的SSB#0~SSB#3所携带的信息相同,以及频点f2对应的SSB#4~SSB#7所携带的信息相同,因此,为节省终端设备搜索SSB的功耗,终端设备可以在一个频点上搜索一个SSB,即终端设备可以在频点f1上搜索一个SSB(比如SSB#0),以及在频点f2上搜索一个SSB(比如SSB#5),进而根据SSB#0的测量值和SSB#5的测量值来确定小区的质量信息。
(3)本申请实施例中是以第一网络设备针对一个小区在两个频点上发送SSB为例进行描述的,为进一步节能,第一网络设备也可以在更多个频点上发送SSB。当第一网络设备在更多个频点上发送SSB时,本申请实施例中的方案也可以适应性调整。比如,当第一网络设备针对第一小区在四个频点上发送SSB时,第一信息也可以用于指示第一小区关联四个SSB,进而终端设备可以根据四个频点上接收到的SSB的测量值来确定第一小区的质量信息。
(4)第一小区关联第一SSB和第二SSB,可以理解为,第一SSB和第二SSB均为网络设备在第一小区上发送的SSB。第一小区关联第一SSB和第二SSB,也可以描述为,第一小区关联第一频点信息和第二频点信息。其中,以第一频点信息为例,第一频点信息可以为用于标识第一频点的信息,比如ARFCN。当终端设备确定第一小区关联第一频点信息和第二频点信息后,可以在第一频点信息对应的频域位置上搜索第一SSB,以及在第二频点信息对应的频域位置上搜索第二SSB。
(5)本申请实施例中所涉及的SSB可以是指小区定义的SSB(cell defined-SSB,CD-SSB)。示例性地,网络设备在一个载波的频率范围内,可以发送多个SSB;在不同频域位置发送的SSB的PCI不必是唯一的,即在不同频域位置发送的SSB可以具有不同的PCI。当某一SSB与剩余最少系统信息(remaining minimum system information,RMSI)(比如SIB1)关联时,该SSB对应于具有唯一NR小区全球标识符(NR cell global identifier,NCGI)的单个小区,该SSB被称为CD-SSB。
本申请实施例中,终端设备确定小区的质量信息的场景可能多种。比如,在小区重选场景(终端设备处于空闲态或非激活态)中,终端设备可以确定当前驻留的小区的质量信息以及当前驻留的小区的邻区的质量信息,以便于执行重选操作。又比如,在小区切换场景(终端设备处于连接态)中,终端设备可以确定当前接入的小区(即源小区)的质量信息以及当前接入的小区的邻区的质量信息,以便于执行切换操作。
下面以小区重选场景和小区切换场景为例,对本申请实施例提供的方案进行详细描述。
实施例一
在实施例一中,将基于小区重选场景,对本申请实施例提供的方案的一种可能的实现进行描述。
首先对小区重选的相关技术特征进行描述。
终端设备在驻留到合适的小区,且停留适当的时间(比如1s)后,可以进行小区重选过程。具体来说,终端设备可以对小区重选的候选列表中满足S准则的小区按照R准则进行排序,其中,满足S准则的小区可以简单理解为质量满足一定要求的小区,按照R准则排序,例如为按照小区的质量从高到低的顺序排序。对于排序最靠前的小区,也就是最高排序小区,当终端设备驻留到当前服务小区的时长大于1s,且该最高排序小区不是终端设备的服务小区的时长大于预设门限时,终端设备读取该最高排序小区的系统信息,确定该 最高排序小区是否允许接入,若是,则终端设备可以重选至该最高排序小区,并继续在该最高排序小区进行如前所述的小区重选过程。
小区重选可以分为同频的小区重选和异频的小区重选(即不同RAT之间的小区重选),与小区重选相关的参数来源于服务小区的系统消息,比如SIB3,SIB4和SIB5。其中,SIB3中包含了小区同频和异频重选的参数信息,比如包括用于小区重选排序R准则的公式计算的参数信息。SIB4中包含了用于同频重选的一个或多个小区的重选配置信息;SIB5中包含了用于异频重选的一个或多个小区的重选配置信息;每个小区的重选配置信息可以包括该小区的标识以及该小区关联的频点信息。
以SIB4中包含的一个或多个小区的重选配置信息为例,在现有方案(比如图5a所示意的方案)中,每个小区关联一个频点信息。参见表1所示,一个或多个小区包括小区1、小区2和小区3,其中,小区1关联的频点信息为ARFCN-1,小区2关联的频点信息为ARFCN-2,小区3关联的频点信息为ARFCN-3。
表1:一个或多个小区的重选配置信息示例
小区的标识 频点信息
小区1 ARFCN-1
小区2 ARFCN-2
小区3 ARFCN-3
基于上述对小区重选的介绍,下面结合图6,描述引入节能方案(比如图5b所示意的方案)后,本申请实施例提供的确定小区的质量信息的方法。
图6为本申请实施例一提供的确定小区的质量信息的方法所对应的流程示意图,如图6所示,包括:
步骤601,第一网络设备发送系统消息,系统消息包括第一信息。
其中,第一信息用于指示第一小区关联第一SSB和第二SSB,第一SSB是通过第一频点发送的,第二SSB是通过第二频点发送的。
相应地,在步骤602中,终端设备可以接收来自第一网络设备的系统消息,并获取第一信息。
下面结合实现方式1和实现方式2对第一信息的两种可能的实现进行详细介绍。
实现方式1:第一信息可以包括一个或多个小区的重选配置信息,其中,一个或多个小区中包括第一小区。第一小区的重选配置信息包括第一小区的标识以及第一小区关联的第一频点信息和第二频点信息。
举个例子,一个或多个小区包括小区1、小区2和小区3,其中小区1关联的第一频点信息为ARFCN-1、第二频点信息为ARFCN-4;小区2关联的第一频点信息为ARFCN-2、第二频点信息为ARFCN-5;小区3关联的第一频点信息为ARFCN-3、第二频点信息为ARFCN-6。参见表2所示,为第一信息所包括的内容的一种示例。
表2:第一信息所包括的内容的一种示例
小区的标识 第一频点信息 第二频点信息
小区1 ARFCN-1 ARFCN-4
小区2 ARFCN-2 ARFCN-5
小区3 ARFCN-3 ARFCN-6
采用该种方式,当第一小区关联两个频点信息时,可以在第一小区的重选配置信息中配置两个频点信息(即对现有方案中小区的重选配置信息进行增改),从而使得终端设备在接收到第一小区的重选配置信息后,可以获知第一小区关联两个频点信息。
需要说明的是,在实现方式1中,上述小区1、小区2和小区3可以为用于同频重选的小区,此种情形下,用于承载第一信息的系统消息可以为SIB4。在其它可能的实施例中,小区1、小区2和小区3也可以为用于异频重选的小区,此种情形下,用于承载第一信息的系统消息可以为SIB5。
实现方式2:第一信息可以包括一个或多个关联关系标识以及每个关联关系标识对应的两个SSB的频点信息;其中,每个关联关系标识对应的两个SSB的频点信息,也可以描述为,每个关联关系标识对应的两个频点信息,比如分别为频点信息1和频点信息2。进一步地,第一小区关联的两个频点信息对应同一关联关系标识。本申请实施例中,关联关系标识用于关联两个SSB的频点信息,关联关系标识可以为关联关系编号等信息,但凡是能够起到关联两个SSB的频点信息作用的信息,均可以理解为关联关系标识。
举个例子,一个或多个关联关系标识包括关联关系1、关联关系2和关联关系3,关联关系1对应的两个频点信息包括ARFCN-1和ARFCN-4,关联关系2对应的两个频点信息包括ARFCN-2和ARFCN-5,关联关系3对应的两个频点信息包括ARFCN-3和ARFCN-6。参见表3所示,为第一信息所包括的内容的一种示例。
表3:第一信息所包括的内容的一种示例
关联关系标识 频点信息1 频点信息2
关联关系1 ARFCN-1 ARFCN-4
关联关系2 ARFCN-2 ARFCN-5
关联关系3 ARFCN-3 ARFCN-6
采用该种方式,当第一小区关联两个频点信息时,第一网络设备在发送第一小区的重选配置信息的基础上(即无需对现有方案中小区的重选配置信息进行增改),还可以向终端设备发送第一信息;相应地,终端设备接收到第一小区的重选配置信息以及第一信息后,可以获知第一小区关联两个频点信息。以第一小区为上述所描述的小区1为例,终端设备根据小区1的重选配置信息(参见表1),获知小区1关联ARFCN-1,以及根据第一信息(参见表3),获知ARFCN-1和ARFCN-4对应于同一关联关系标识,进而可以确定小区1关联两个频点信息(分别为ARFCN-1和ARFCN-4)。
需要说明的是:在实现方式2中,第一信息可以承载在系统消息(比如SIB4或SIB5)中,比如可以在系统消息中新增一个域,用于承载第一信息。在其它可能的实施例中,第一信息也可以承载在其它可能的消息中,具体不做限定;或者,第一信息也可以为协议预先定义的,此种情形下,终端设备也可以无需再从第一网络设备获取第一信息。本申请实 施例中,以第一信息承载在系统消息中为例进行描述。
本申请实施例中,第一小区可以为终端设备当前驻留的小区,此种情形下,第一小区为第一网络设备覆盖范围内的小区。或者,第一小区也可以为终端设备驻留的小区(比如第二小区)的邻区,此种情形下,第一小区可以为第一网络设备覆盖范围内的小区,或者也可以为其它网络设备覆盖范围内的小区,也就是说,终端设备可以通过对多个小区应用本申请实施例提供的测量方法,来确定小区的质量信息,进而更准确地进行小区重选,提高通信质量。
步骤603,终端设备根据第一SSB的测量值、第二SSB的测量值确定第一小区的质量信息。
其中,终端设备根据第一SSB的测量值、第二SSB的测量值确定第一小区的质量信息的方式可以有多种。
在一种可能的实现方式中,第一网络设备可以向终端设备发送辅助参数信息,辅助参数信息包括预设阈值、第一SSB的测量值的系数、第二SSB的测量值的系数;其中,预设阈值用于确定第一SSB的测量值和第二SSB的测量值能否进行合并计算;第一SSB的测量值的系数可以理解为第一SSB的测量值参与合并计算时所对应的权重,或者,第一SSB的测量值参与合并计算时对第一小区的质量信息的贡献比例;第二SSB的测量值的系数的含义可以参照第一SSB的测量值的系数,不再赘述。相应地,终端设备接收辅助参数信息,并根据第一SSB的测量值、第二SSB的测量值和辅助参数确定第一小区的质量信息。
比如,若第一SSB的测量值和第二SSB的测量值均大于或等于预设阈值,则根据第一SSB的测量值的系数和第二SSB的测量值的系数对第一SSB的测量值和第二SSB的测量值进行合并计算,来确定第一小区的质量信息。举个例子,第一SSB的测量值为X,第二SSB的测量值为Y,且X和Y都超过了预设阈值(M)。第一SSB的测量值的系数为a,第二SSB的测量值的系数为b,终端设备可以确定第一小区的质量信息是一个关于X、Y、a、b的函数值,即f(X,Y,a,b),比如f(X,Y,a,b)=a*X+b*Y。采用该种方式,通过设定和应用预设阈值,能够有效保证参与合并计算的SSB的测量值较为合理;进一步地,考虑到不同SSB的频域位置不同,进而对小区的质量信息的贡献率也不同,比如若SSB的中心频域位置与小区的中心频域位置较近,则对小区的质量信息的贡献率较大,若SSB的中心频域位置与小区的中心频域位置较远,则对小区的质量信息的贡献率较小,进而在进行合并计算时,通过设定和应用每个SSB的测量值的系数,使得确定的小区的质量信息更为准确。
又比如,若第一SSB的测量值大于或等于预设阈值,第二SSB的测量值小于预设阈值,则终端设备可以根据第一SSB的测量值确定第一小区的质量信息,通过设定和应用预设阈值,终端设备可以去除不合理的SSB测量值,以提高确定小区的质量信息的准确性。
又比如,第一SSB的测量值小于预设阈值,第二SSB的测量值大于或等于预设阈值,则终端设备可以根据第二SSB的测量值确定第一小区的质量信息。通过设定和应用预设阈值,终端设备可以去除不合理的SSB测量值,以提高确定小区的质量信息的准确性。
又比如,第一SSB的测量值和第二SSB的测量值均小于预设阈值,则终端设备可以根据第一SSB的测量值和第二SSB的测量值中的最大测量值确定第二小区的质量信息。
示例性地,辅助参数信息可以为第一网络设备通过系统消息发送给终端设备的。辅助参数信息和第一信息可以承载于同一条系统消息,或者,也可以承载于不同的系统消息, 具体不做限定。
需要说明的是,上述实施例一中,是第一小区为例进行描述的,具体实施中,当多个小区均关联两个频点信息时,终端设备可以采用上述方式确定多个小区的质量信息,进而基于确定出的多个小区的质量信息执行小区重选操作。由于本申请实施例中的方案能够有效提高小区的质量信息的准确性,从而为终端设备执行小区重选操作提供了更为准确的依据。
实施例二
在实施例二中,将基于小区切换场景,对本申请实施例提供的方案的一种可能的实现进行描述。
首先对小区切换的相关技术特征进行描述。
当处于连接态的终端设备从一个小区移动到另一个小区时,为了保持不中断通信,需要进行小区切换过程。具体来说,第一网络设备可以向终端设备发送测量控制信息;终端设备接收到测量控制信息后,可以对服务小区和/或邻区进行测量,如果测量控制消息中配置了S测量(S-Measure),则需要根据S测量的配置来判断是否需要执行邻区测量(可以包括同频、异频);当满足测量上报条件时,终端设备可以将测量结果上报给第一网络设备。
示例性地,测量控制信息可以包括测量对象、上报配置和测量标识等。其中,(1)测量对象可以为一个频点信息,终端设备可以根据该频点信息接收SSB并进行测量。
(2)上报配置包含关于测量上报的三种类型及其相关的配置,其中测量上报的三种类型分别为:类型1,测量事件触发一次上报;其中,测量事件可以包括A1-A5、B1、B2,上报次数为一次。类型2,周期性上报;类型3,测量事件触发周期性上报;其中,触发事件包括A1-A5、B1、B2,上报次数为多次。其中,A1-A5用于系统内测量,A1:服务小区的质量高于一定的门限值;A2:服务小区的质量低于一定的门限值;A3:邻区质量高于服务小区一定值;A4:邻区质量高于一定门限值;A5:服务小区的质量低于一定的门限值,邻区高于一定的门限值。B1、B2用于系统间测量,B1:邻区的质量高于一定的门限值;B2,服务小区的质量低于一定的门限值,邻区的质量高于一定的门限值。
当测量上报的类型为类型1或类型3时,上报配置中可以包括测量事件标识。
(3)测量标识用于将一种上报配置和一个测量对象相关联,即一个测量标识用于标记一个测量对象+一种上报配置。如图7所示,一个测量对象可以和不同的上报配置相关联,一个上报配置也可以和不同的测量对象相关联。
基于上述介绍,下面结合图8,描述引入节能方案(比如图5b所示意的方案)后,本申请实施例提供的确定小区的质量信息的方法。
图8为本申请实施例二提供的确定小区的质量信息的方法所对应的流程示意图,如图8所示,包括:
步骤801,第一网络设备发送RRC消息,RRC消息包括第一信息。
其中,第一信息用于指示第一小区关联第一SSB和第二SSB,第一SSB是通过第一频点发送的,第二SSB是通过第二频点发送的。
相应地,在步骤802中,终端设备可以接收来自第一网络设备的RRC消息,并获取第一信息。
示例性地,RRC消息可以为RRC连接重配置消息或RRC重配置消息,或者也可以为RRC连接恢复消息或RRC恢复消息或RRC释放消息,具体不做限定。
第一信息可以包括一个或多个小区的测量对象配置信息,一个或多个小区中包括第一小区,第一小区的测量对象配置信息包括第一小区的第一测量对象和第二测量对象。其中,第一测量对象可以为第一小区关联的第一频点信息,第二测量对象可以为第一小区关联的第二频点信息。进而,终端设备接收到第一信息后,可以获知第一小区关联两个频点信息。
本申请实施例中,第一小区可以为终端设备当前接入的小区(即服务小区),此种情形下,第一小区为第一网络设备覆盖范围内的小区。或者,第一小区也可以为终端设备接入的小区(比如第二小区)的邻区,此种情形下,第一小区可以为第一网络设备覆盖范围内的小区,或者也可以为其它网络设备(比如第二网络设备)覆盖范围内的小区。
以第一小区为服务小区为例,服务小区对应的测量对象(measObjectId)可以由服务小区的配置信元ServingCellConfig中的servingCellMO字段来指示。由于目前的方案中,服务小区的配置信元中仅配置一个servingCellMO字段,因此,当引入节能方案(即服务小区关联两个频点信息)后,可以在服务小区的配置信元中再增加一个servingCellMO字段,即配置两个servingCellMO字段。
步骤803,终端设备根据第一SSB的测量值、第二SSB的测量值确定第一小区的质量信息。
其中,终端设备根据第一SSB的测量值、第二SSB的测量值确定第一小区的质量信息的方式可以有多种。在一种可能的实现方式中,第一网络设备可以向终端设备发送辅助参数信息,辅助参数信息包括预设阈值、第一SSB的测量值的系数、第二SSB的测量值的系数,进而终端设备接收辅助参数信息,并根据第一SSB的测量值、第二SSB的测量值和辅助参数确定第一小区的质量信息。具体实现可以参照实施例一中的描述。
步骤804,终端设备确定第一小区的质量信息满足测量事件标识对应的上报条件,则向第一网络设备上报第一小区的质量信息。
示例性地,RRC消息中还可以包括测量事件标识,比如测量事件标识可以为测量事件A1的标识,第一小区为服务小区,终端设备确定第一小区的质量信息满足测量事件标识对应的上报条件可以是指终端设备确定出服务小区的质量信息后,确定服务小区的质量高于一定的门限值。
需要说明的是,上述是以终端设备根据第一SSB的测量值和第二SSB的测量值确定第一小区的质量信息并上报给第一网络设备为例进行描述的。在其它可能的实施例中,终端设备也可以将第一SSB的测量值和第二SSB的测量值分别上报给第一网络设备,又或者,将第一SSB的测量值和第二SSB的测量值中最大测量值上报给第一网络设备,具体不做限定。
进一步地,第一网络设备接收到终端设备上报的测量结果后,可以根据测量结果指示终端设备执行小区切换。
二、针对于问题2
终端设备接收到SSB后,可以根据SSB的频域位置来确定频域参考点(PointA)。由于在5G通信系统中,频带宽度大幅增加,频域资源分配的灵活度增加,因此弱化了中心频点的概念,而使用Point A作为频域上的参考点来进行资源的分配。进一步地,Point A 即为公共资源块(common resource block,CRB)的子载波0的中心;由于5G通信系统不同的资源可能使用不同的子载波间隔,比如SSB、物理上行共享信道(physical uplink shared channel,PUSCH)可能拥有各自不同的子载波间隔,CRB相当于一个标尺,用于定位这些资源的位置。
参见图9所示,终端设备接收到SSB后,可以获得SSB的频点下边界位置(Kssb),然后从MIB中的ssb-subcarrierOffset字段获取偏移量1以及从SIB1中的OffsetToPoint A字段获取偏移量2,其中,ssb-subcarrierOffset字段所承载的偏移量1表示SSB的频域下边界位置与SSB所映射的子载波编号最小的子载波所在的CRB的频域下边界位置之间的频域偏移量,OffsetToPointA字段所承载的偏移量2是指SSB所映射的子载波编号最小的子载波所在的CRB与频域参考点之间的频域偏移量。进而终端设备可以根据Kssb以及这两个偏移量来获知PointA的位置,如下公式所示:
Point A=Kssb+ssb-subcarrierOffset+OffsetToPointA
其中,有关ssb-subcarrierOffset和OffsetToPointA的具体描述可以参见相关现有技术,此处不再赘述。
然而,当一个小区关联两个频点信息时,终端设备1可能会根据第一频点信息接收到SSB#1,终端设备2可能会根据第二频点信息接收到SSB#5,由于MIB和SIB1中的两个参数ssb-subcarrierOffset和OffsetToPoint1是多个终端设备共用的,从而会使得不同终端设备计算出来的PointA位置不同,造成后续网络设备在资源分配时出现错误。
基于此,本申请实施例提供一种确定频域参考点的方法,用于使得终端设备能够准确确定频域参考点。
下面结合实施例三对本申请实施例提供的确定频域参考点的方法进行描述。
实施例三
终端设备从第二网络设备接收第二信息,第二信息可以承载于第一系统消息,第一系统消息可以为SIB1。其中,第二信息包括第一偏移量和第二偏移量;第一偏移量为第一SSB所映射的子载波编号最小的子载波所在的第一CRB与频域参考点之间的频域偏移量,第二偏移量为第二SSB所映射的子载波编号最小的子载波所在的第二CRB与频域参考点之间的频域偏移量。举个例子,SIB1中可以包括两个OffsetToPointA字段,两个OffsetToPointA字段分别对应不同的频点信息,比如两个OffsetToPointA字段分别为OffsetToPointA字段1和OffsetToPointA字段2,OffsetToPointA字段1用于承载第一偏移量,OffsetToPointA字段2用于承载第二偏移量。
以及,终端设备还可以从第二网络设备接收第三信息,第三信息可以承载于第二系统消息,第二系统消息可以为MIB。其中,第三信息包括第三偏移量和第四偏移量;第三偏移量为第一SSB的频域下边界位置与第一CRB的频域下边界位置之间的频域偏移量,第四偏移量为第二SSB的频域下边界位置与第二CRB的频域下边界位置之间的频域偏移量。举个例子,MIB中可以包括两个ssb-subcarrierOffset字段,两个ssb-subcarrierOffset字段分别对应不同的频点信息,比如两个ssb-subcarrierOffset字段分别为ssb-subcarrierOffset字段1和ssb-subcarrierOffset字段2,ssb-subcarrierOffset字段1用于承载第三偏移量,ssb-subcarrierOffset字段2用于承载第四偏移量。
进一步地,第一SSB的频点信息和第二SSB的频点信息不同,比如第一SSB的频点信息为频点信息1,第二SSB的频点信息为频点信息2;第一SSB和第二SSB可以关联同一小区,比如第一小区,上述第二信息或第三信息为第二网络设备在第一小区上发送的。
当终端设备确定第一SSB为服务SSB后,可以根据第一偏移量和第三偏移量采用上述公式确定频域参考点。或者,当终端设备确定第二SSB为服务SSB后,可以根据第二偏移量和第四偏移量确定频域参考点。其中,针对于第一小区,终端设备接收第一SSB,并基于第一SSB与第一小区建立时域同步,此种情形下,可以理解为终端设备确定第一SSB为服务SSB。
示例性地,两个OffsetToPointA字段分别对应不同的频点信息,以及两个ssb-subcarrierOffset字段分别对应不同的频点信息的具体实现方式可能有多种。下面以两个ssb-subcarrierOffset字段分别对应不同的频点信息为例,描述两种可能的方式。
方式1,MIB中可以携带指示信息,指示信息用于指示两个ssb-subcarrierOffset字段与两个频点信息之间的关联关系,比如ssb-subcarrierOffset字段1对应频点信息1,ssb-subcarrierOffset字段2对应频点信息2。如此,终端设备根据频点信息1接收到第一SSB后,根据MIB中的指示信息,可以获知频点信息1对应于ssb-subcarrierOffset字段1,进而将ssb-subcarrierOffset字段1中承载的第三偏移量作为确定频域参考点应该使用的偏移量。
方式2,网络设备分别根据不同的频点信息发送各自的MIB,比如根据频点信息1发送MIB1,MIB1中携带ssb-subcarrierOffset字段1,以及根据频点信息2发送MIB2,MIB2中携带ssb-subcarrierOffset字段2。如此,终端设备根据频点信息1接收到第一SSB后,可以将MIB1的ssb-subcarrierOffset字段1中承载的第三偏移量作为确定频域参考点应该使用的偏移量。
需要说明的是,SIB1携带OffsetToPointA字段的情形可以适应性参照上述方式1和方式2,具体不再赘述。
本申请实施例中,考虑到第三偏移量和第四偏移量有可能相同,因此,当第三偏移量和第四偏移量相同时,也可以采用现有方案,即MIB包括一个ssb-subcarrierOffset字段,该ssb-subcarrierOffset字段所承载的偏移量为多个终端设备共用的。
针对于上述实施例一至实施例三,需要说明的是:

②当实施例一与实施例三结合实施时,实施例一中的第一小区和实施例三中的第一小区可以为同一小区。比如,当第一小区为终端设备驻留的小区时,第一网络设备和第二网络设备可以为同一网络设备;此种情形下,终端设备驻留在第一小区时,可以根据实施例一中的方案进行小区重选以及根据实施例三中的方案接收第一小区关联的SSB并确定频域参考点,其中,小区重选操作和确定频域参考点的操作可以同时执行,或者也可以不同时执行,具体不做限定。
又比如,当第一小区为终端设备驻留的小区的邻区时,第一网络设备和第二网络设备可能为同一网络设备或者也可能为不同的网络设备;此种情形下,终端设备根据实施例一 中的方案重选到第一小区后,可以根据实施例三中的方案接收第一小区关联的SSB并确定频域参考点。
③当实施例二与实施例三结合实施时,实施例二中的第一小区和实施例三中的第一小区可以为同一小区。比如,当第一小区为终端设备接入的小区时,第一网络设备和第二网络设备可以为同一网络设备,此种情形下,终端设备在接入第一小区之前,可以根据实施例三中的方案接收第一小区关联的SSB并确定频域参考点,以及在接入第一小区之后,可以根据实施例二中的方案进行小区切换。
又比如,当第一小区为终端设备接入的小区的邻区时,第一网络设备和第二网络设备可能为同一网络设备或者也可能为不同的网络设备。此种情形下,终端设备可以根据实施例二中的方案切换到第一小区,以及在切换到第一小区之前根据实施例三中的方案接收第一小区关联的SSB并确定频域参考点。
