Description
本申请实施例涉及通信技术领域,特别涉及一种小区测量方法、装置、设备及存储介质。

然而,相关技术中L3测量机制处理速度较慢(因为有L3滤波过程,需要平均多次采样结果)且需要RRC过程触发切换,当L3测量机制用于测量高频小区时,频繁的RRC切换带来的信令开销较高,L3测量机制不利于实现频繁切换背景下的快速切换。

为使本申请的目的、技术方案和优点更加清楚,下面将结合附图对本申请实施方式作进一步地详细描述。
首先介绍本申请涉及的一些相关知识:
L3(层3)测量:为了对终端设备进行小区间移动性管理控制,网络设备通常会给终端设备配置L3测量相关配置,终端设备基于网络设备配置的L3测量相关配置进行邻区测量。
当L3测量邻区时,需要同时知道该小区的频点和PCI(Physical Cell Identity,物理小区标识)信息,其中,网络设备通过专用信令或者***广播消息向终端设备发送频点信息;可选的,网络设备也可以进一步为终端设备提供一个待测量频点关联的一个或者多个PCI信息,从而辅助终端设备更加快速的执行测量,但PCI信息是可选配置。
如果网络设备只为终端设备配置了频点信息,那么终端设备需要通过实现方式识别该频点下可能测到的全部小区,新空口(NewRadio,NR)***中PCI一共有1008种,理论上来讲,对于一个待测量频点,终端设备需要最多尝试1008次才能将该频点下的全部小区测量识别出来。
针对处于连接态的终端设备,网络设备通过专用信令将L3测量相关配置发送给终端设备,专用信令发送的L3测量相关配置至少包括如下几个部分:
(1)至少一个需要进行添加或修改操作的MO(Measurement Object,测量目标),和/或,至少一个需要进行删除操作的MO;
一个MO通常包括一个待测量频点的标识,以及该待测量频点对应的测量参考信号关联的SMTC(Synchronization signal/physical broadcast channel(SS/PBCH)block Measurement Time Configuration,同步测量时间配置)配置。其中,待测量频点的标识用于告知该MO对应的待测量频点,待测量频点对应的测量参考信号可以是SSB(Synchronization Signal/physical broadcast channel Block,同步信号/物理广播信道块)(也可简写为SS/PBCH block)或者CSI-RS(Channel State Information Reference Signal,信道状态信息参考信号),测量参考信号关联的SMTC配置用于告知测量参考信号出现的时域位置,即:测量窗口信息,通常测量参考信号是周期性出现的,因而SMTC窗口也是周期性出现的,SMTC配置通常包括测量周期、测量偏移量以及测量长度配置。
(2)至少一个需要进行添加或修改操作的测量上报配置,和/或,至少一个需要进行删除操作的测量上报配置;
基于网络设备配置的MO,终端设备能获取邻区L3测量的测量结果,但终端设备仍不知道何时上报测量结果以及上报的测量结果的格式,所以除了MO配置,网络设备还会配置测量上报配置,用于控制终端设备的测量上报行为。通常测量上报配置包括测量参考信号,测量事件以及测量量等信息,其中,测量参考信号可以是SSB或者CSI-RS,测量事件可以是周期性触发测量事件或者事件性触发测量事件,测量量可以是RSRP(Reference Signal Received Power,参考信号接收功率)、RSRQ(Reference Signal Received Quality,参考信号接收质量)或SINR(Signal to Interference plus Noise Ratio,信噪比)中的至少一种。
(3)至少一个需要进行添加或修改操作的测量ID,和/或,至少一个需要进行删除操作的测量ID;
一个测量ID关联一个MO和一个测量上报配置,从而实现多个MO与多个测量上报配置的多对多映射关系,测量上报以测量ID为单位进行上报,即:一次测量上报包括一个测量ID对应的测量结果。
L1(层1)测量:在高频背景下小区通常会采用多波束方式进行通信,随着终端设备在小区内移动,终端设备的最佳服务波束可能发生变化,为了让网络设备及时调整终端设备的服务波束,相关技术引入了波束管理内容,由于处于空闲态或者非激活态的终端设备的波束管理属于终端设备实现,因而相关技术中的波束管理内容只针对处于连接态的终端设备。示例性的,层1是指物理层。
服务小区(Serving Cell):至少包括主小区(Primary Cell,PCell),同时可选包括辅小区(Secondary Cell,SCell)以及主辅小区(Primary Secondary Cell,PSCell)中的至少一种,是指与终端设备建立无线资源控 制(Radio Resource Control,RRC)连接并为终端设备提供服务的小区。
邻区(Neighbor Cell,NCell):又称为邻居小区(或相邻小区、邻小区等),是指终端设备当前接入服务小区以外的其他小区。
图1示出了本申请一个实施例提供的移动通信***的结构示意图。该移动通信***可以是LTE***或者为第五代移动通信技术(the 5th generation mobilecommunication,5G),又称NR***。该移动通信***包括:网络设备120和终端设备140。
网络设备120可以是基站,该基站可用于将接收到的无线帧与IP分组报文进行相互转换,还可协调对空中接口的属性管理。例如,基站可以LTE中的演进型基站(eNB或e-NodeB,evolutional Node B),或者,5G***中采用集中分布式架构的基站。
可选的,图1所示的移动通信***中,不同网络设备120对应各自的无线信号覆盖范围(以网络设备120为圆心的圆形区域),该无线信号覆盖范围被称为小区,且不同小区之间存在交集。在其他可能的实施方式中,同一网络设备120可以对应多个小区,且各个小区对应不同的标识,本申请实施例并不对此进行限定。
网络设备120和终端设备140通过无线空口建立无线连接。可选地,该无线空口是基于LTE(Long Term Evolution,长期演进)标准的无线空口;或者,该无线空口是基于5G标准的无线空口,比如该无线空口是NR;或者,该无线空口也可以是基于5G的更下一代移动通信网络技术标准的无线空口。
终端设备140可以是指向用户提供语音和/或数据连通性的设备。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进行通信,终端设备140可以是移动终端设备,如移动电话(或称为“蜂窝”电话)和具有移动终端设备的计算机,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。例如,订户单元(Subscriber Unit)、订户站(Subscriber Station)、移动站(Mobile Station)、移动台(Mobile)、远程站(RemoteStation)、接入点(Access Point)、远程终端设备(Remote Terminal)、接入终端设备(AccessTerminal)、用户装置(User Terminal)、用户代理(User Agent)、用户设备(User Device)、或用户终端设备(User Equipment)。
本申请各个实施例提供的小区测量方法,即用于终端设备140在RRC空闲态或RRC非激活态或RRC连接态下对邻区进行信号测量的场景。
下面将展开介绍各个实施例。
图2示出了本申请一个示例性实施例提供的小区测量方法的流程图,以该方法由终端设备执行进行举例说明,该方法包括:
步骤220,基于L1测量配置,执行邻区L1测量;
在一些实施例中,终端设备基于用于执行邻区L1测量的测量参考信号配置,执行邻区L1测量;
或者,终端设备基于用于执行邻区L1测量的测量参考信号配置,以及用于执行邻区L1测量的测量间隔配置,执行邻区L1测量;
或者,终端设备基于用于执行邻区L1测量的测量参考信号配置、用于执行邻区L1测量的测量间隔配置,以及用于执行邻区L1测量的L1测量间隔共享配置,执行邻区L1测量。
在一些实施例中,用于执行邻区L1测量的L1测量配置,通过如下消息中的任意一种进行配置:
·RRC(Radio Resource Control,无线资源控制)消息;
·***广播消息;
·MAC CE(Media Access Control Control Element,媒体接入控制控制单元)消息;
·DCI(Downlink Control Information,下行控制信息)消息。
在一些实施例中,用于执行邻区L1测量的L1测量配置,还可以通过如下任意一种消息进行配置添加或进行配置更新或进行配置删除或进行配置去激活操作:
·RRC消息;
·***广播消息;
·MAC CE消息;
·DCI消息。
需要说明的是,步骤220中“执行邻区L1测量”可能被替换为“执行服务小区L1测量”,在这种情况下,“服务小区L1测量”包括服务小区L1测量和邻区L1测量,因为,在执行L1测量任务时,网络设备将服务小区L1测量的相关配置和邻区L1测量的相关配置发送至终端设备,而终端设备可能并不区分对服务小区的测量和对邻区的测量。示例性的,网络设备将频点1和PCI 1的服务小区、频点1和PCI 2的邻区以及频点1和PCI 3的邻区的L1测量相关配置发送至终端设备,终端设备执行对上述小区的L1测量。一种定义规则下,服务小区L1测量只包括对频点1和PCI 1对应小区的L1测量,而对频点1和PCI 2对 应小区以及频点1和PCI 3对应小区的L1测量则称为邻区L1测量;在另外一种定义规则下,同时将对频点1和PCI 1对应小区的L1测量和对频点1和PCI 2对应小区以及频点1和PCI 3对应小区的L1测量统称为广义上的“服务小区L1测量”,本申请对上述定义规则不作限定。
综上所述,终端设备基于L1测量配置,可执行邻区L1测量,扩展了L1测量的使用范围,相比于L3测量机制,L1测量机制降低了频繁切换场景下的终端设备的服务中断时延。
图3示出了本申请一个示例性实施例提供的小区测量方法的流程图,以该方法由终端设备执行进行举例说明,该方法包括:
步骤320,基于测量参考信号配置,执行邻区L1测量。
在一些实施例中,步骤220中的L1测量配置包括:用于执行邻区L1测量的测量参考信号配置。可选的,测量参考信号包括SSB,测量参考信号配置包括待测量邻区的SSB资源对应的配置;或,测量参考信号包括CSI-RS,测量参考信号配置包括待测量邻区的CSI-RS资源对应的配置;或,测量参考信号包括SSB和CSI-RS,测量参考信号配置包括待测量邻区的SSB资源对应的配置和待测量邻区的CSI-RS资源对应的配置。

·待测量邻区的小区标识;
·待测量邻区的至少一个SSB标识;
·待测量邻区的SSB资源对应的参考信号测量窗口配置。
可选的,参考信号测量窗口配置用于指示待测量邻区的SSB资源所在的时域资源位置,便于终端设备精准测量邻区的SSB参考信号,获取测量结果。
可选的,参考信号测量窗口配置的配置方式至少包括以下三种。
第一种可能的配置方式:邻区L1测量完全复用L3测量配置中为对应频点配置的测量窗口配置;
可选的,邻区L1测量完全复用L3测量配置中为对应频点配置的测量窗口配置,可替换为,邻区L1测量对应的测量窗口配置与L3测量配置中为对应频点配置的测量窗口配置相同。
在一些实施例中,L3测量配置用于终端设备基于L3测量配置对邻区执行L3测量。L3测量配置中配置有对应频点配置的测量窗口配置,如下表1所示:
表1
其中,N为大于等于1的正整数。
示例性的,邻区L1测量为对频点2的邻区L1测量,如果邻区L1测量复用L3测量配置中为对应频点配置的测量窗口配置,则对频点2的邻区L1测量应该使用表1中与频点标识2关联的测量窗口配置2。
第二种可能的配置方式:邻区L1测量独立配置对应的测量窗口配置,也即,邻区L1测量与L3测量各自独立配置测量窗口配置;
可选的,邻区L1测量独立配置对应的测量窗口配置,可替换为,邻区L1测量对应的测量窗口配置与L3测量配置中为对应频点配置的测量窗口配置不同,或者,邻区L1测量对应的测量窗口配置与L3测量配置中为对应频点配置的测量窗口配置相互独立。
在一些实施例中,L1测量配置中的测量窗口配置,如下表2所示:
表2
其中,M为大于等于1的正整数。
在一些实施例中,表2中L1测量对应的测量窗口配置按照PCI粒度配置;或者,按照频点和PCI组合粒度配置;或者,按照小区粒度配置;或者,L1测量对应的测量窗口配置按照SSB资源或者CSI-RS资源粒度配置,本申请对L1测量对应的测量窗口配置所基于的配置粒度不作限定。
可选的,按照PCI粒度配置,即一个PCI或者一组PCI(一组PCI对应同一个频点)配置一套测量窗口配置;
可选的,按照频点和PCI组合粒度配置,即一个频点和PCI的组合或者一组频点和PCI的组合配置一套测量窗口配置;
可选的,按照小区粒度配置,即一个小区标识或者一组小区标识配置一套测量窗口配置;
可选的,按照SSB资源或者CSI-RS资源粒度配置,即一套测量窗口配置对应一组SSB资源配置和/或一组CSI-RS资源配置。
第三种可能的配置方式:邻区L1测量复用L3测量配置中为对应频点配置的测量窗口配置中的部分配置;
可选的,邻区L1测量复用L3测量配置中为对应频点配置的测量窗口配置中的部分配置,可替换为,邻区L1测量对应的测量窗口配置中的部分或全部配置与L3测量配置中为对应频点配置的测量窗口配置中的部分或全部配置相同。
第三种可能的配置方式是上述第一种可能的配置方式和第二种可能的配置方式的结合。可选的,测量窗口配置包括三部分参数:参考信号测量窗口出现的周期、参考信号测量窗口出现的周期内偏移量以及参考信号测量窗口持续时长配置,但如果对于同一频域资源的L3测量对应的测量窗口配置与L1测量对应的测量窗口配置部分参数配置取值相同,则对应频域资源的L1测量对应的测量窗口配置只需要配置差异部分,其余部分仍然复用对应频域资源的L3测量对应的测量窗口配置,这种方式可以节省配置信令开销。
在一些实施例中,第三种可能的配置方式如下表3所示:
表3
L1测量对应的测量窗口配置包含如下信息: |
参数1:参考信号测量窗口出现的周期 |
参数2:参考信号测量窗口出现的周期内偏移量 |
参数3:参考信号测量窗口持续时长配置 |
如表3所示,如果邻区L1测量对应的测量窗口配置中的部分参数不配置或者不出现,则认为该参数取值与同一频域资源的L3测量配置对应的测量窗口配置中的同一参数取值相同;相反,如果邻区L1测量对应的测量窗口配置中的部分参数配置或出现,则使用邻区L1测量对应的测量窗口配置中包含的对应参数执行邻区L1测量。
示例性的,对于一个频域资源,L1测量配置中该频域资源对应的测量窗口配置中只包含参数1,则该频域资源对应的L1测量窗口配置中的参数2和参数3应该使用同一频域资源的L3测量配置对应的测量窗口配置中的参数2和参数3。
在一些实施例中,对于上述第二种可能的配置方式和/或第三种可能的配置方式,参考信号测量窗口配置包括以下中的至少一种:
·参考信号测量窗口出现的周期;
·参考信号测量窗口出现的周期内偏移量;
·参考信号测量窗口的持续时长;
·参考信号测量窗口关联的时间参考小区对应的小区标识信息。
由于参考信号测量窗口配置对应的时域测量窗口是一个相对时间窗口,需要确定一个基准时间才能工作,而在一般情况下,参考信号测量窗口配置对应的基准时间为服务小区时间,此时,参考信号测量窗口关联的时间参考小区对应的小区标识信息不出现或者不配置,就表明该参考信号测量窗口默认以服务小区时间为基准时间;但如果参考信号测量窗口对应的基准时间不是服务小区,就需要通过参考信号测量窗口关联的时间参考小区对应的小区标识信息显性指出该参考信号测量窗口到底是以哪个小区的时间为基准时间。
在另一些实施例中,第三种可能的配置方式还可进一步优化:
L1的参考信号测量窗口配置只配置相同参数不同取值的差值部分。
示例性的,对于一个频域资源,L1测量配置中该频域资源对应的参考信号测量窗口配置中只包含参数1的差值部分,则该频域资源对应的参考信号测量窗口配置中的参数2和参数3应该使用同一频域资源的L3测量配置对应的参考信号窗口配置中的参数2和参数3。
该频域资源对应的L1测量的参考信号窗口配置中的参数1,取值等于同一频域资源的L3测量对应的参考信号窗口配置中的参数1加上或者减去L1测量配置中该频域资源对应的参考信号窗口配置中包含的参数1的差值。
在进一步优化的第三种可能的实施方式下,参考信号测量窗口配置包括以下中的至少一种:
·第一周期相对于第二周期的偏差值,第一周期是L1测量配置中参考信号测量窗口出现的周期,第 二周期是L3测量配置中对应频点关联的MO中的SMTC配置中对应的周期;
·第一偏移量相对于第二偏移量的偏差值,第一偏移量是L1测量配置中参考信号测量窗口出现的周期内偏移量,第二偏移量是L3测量配置中对应频点关联的MO中的SMTC配置中对应的周期内偏移量;
·第一持续时长相对于第二持续时长的偏差值,第一持续时长是L1测量配置中参考信号测量窗口的持续时长,第二持续时长是L3测量配置中对应频点关联的MO中的SMTC配置中对应的参考信号测量窗口的持续时长。
可以理解的是,在L1测量配置包含参考信号测量窗口配置的情况下,执行第二种或第三种可能的配置方式;在L1测量配置不包含参考信号测量窗口配置的情况下,终端设备采用上述第一种可能的配置方式确定执行邻区L1测量对应需要的参考信号测量窗口。
在一些实施例中,基于上述第一至第三种可能的配置方式,终端设备在执行步骤320之前还包括:在一次配置过程中参考信号测量窗口配置不出现或者不配置的情况下,使用上次配置过程的参考信号测量窗口配置,或,使用L3测量配置中对应频点关联的MO中的SMTC配置。
针对测量参考信号包括CSI-RS的情况,在一些实施例中,待测量邻区的CSI-RS资源对应的配置,包括以下中的至少一种:
·待测量邻区的小区标识;
·待测量邻区的至少一个CSI-RS资源对应的逻辑标识;
·待测量邻区的至少一个CSI-RS资源对应的时域资源配置;
·待测量邻区的至少一个CSI-RS资源对应的频域资源配置;
·待测量邻区的至少一个CSI-RS资源关联的QCL(Quasi Co-Location,准共址)参考信号配置。
可选的,准共址QCL参考信号配置对应的准共址参考信号的类型为SSB或者CSI-RS。
需要说明的是,步骤320中“执行邻区L1测量”可能被替换为“执行服务小区L1测量”,在这种情况下,“服务小区L1测量”包括服务小区L1测量和邻区L1测量,具体解释请参考步骤220对应部分描述,此处不再赘述。
综上所述,L1测量配置包括测量参考信号配置,进一步提供了L1测量配置用于执行邻区L1测量的实现方式,通过L1测量快速实现邻区测量,保证了L1/L2切换机制的低时延测量需求。
基于图3所示的可选实施例,测量参考信号配置可能按照不同的粒度进行配置,可选的,按照不同粒度进行配置的方式至少包括以下三种:
·测量参考信号配置按照PCI粒度配置;
在一些实施例中,测量参考信号配置按照PCI粒度配置包含两种可能含义。
1,测量参考信号配置与PCI信息直接关联;
可选的,测量参考信号配置还包括PCI信息,针对每一个PCI直接关联一套待测量邻区的SSB资源对应的L1测量配置和/或待测量邻区的CSI-RS资源对应的L1测量配置。
表4示出了测量参考信号配置与PCI粒度直接关联的示意图。
表4
示例性的,表4示出了测量参考信号配置包含三个PCI标识,每一个PCI标识关联一组待测量邻区的SSB资源对应的L1测量配置和/或待测量邻区的CSI-RS资源对应的L1测量配置的情形。
当然,本申请也不排除一组PCI标识配置一套待测量邻区的SSB资源对应的L1测量配置和/或待测量邻区的CSI-RS资源对应的L1测量配置的配置形式,示例如表5。
表5
与表4不同在于,表5中一个PCI标识列表包含一个或者多个PCI标识,每一个PCI标识列表关联一组待测量邻区的SSB资源对应的L1测量配置和/或待测量邻区的CSI-RS资源对应的L1测量配置。
2,测量参考信号配置与PCI信息间接关联;
可选的,测量参考信号配置还包括PCI信息,针对每一个PCI间接关联一套待测量邻区的SSB资源对应的L1测量配置和/或待测量邻区的CSI-RS资源对应的L1测量配置。
表6示出了测量参考信号配置与PCI信息间接关联的示意图。
表6
表7示出了与测量参考信号配置相关的配置信息的结构示意图。
表7
结合表6和表7可看出,测量参考信号配置并没有直接包含PCI标识或者PCI标识列表,但是每一套待测量邻区的SSB资源对应的L1测量配置和/或待测量邻区的CSI-RS资源对应的L1测量配置通过一个逻辑标识(即:逻辑标识1或逻辑标识2或逻辑标识3)间接关联一个PCI标识或者一组PCI标识(即:一个PCI标识列表)。间接关联的好处在于,如果表7中的PCI相关的参数多次出现在其他配置参数(比如表6中的测量参考信号配置)中时,其他配置参数只需要将表7对应的逻辑标识添加到自身配置中就可以实现参数间接关联,相比每次直接添加PCI相关参数的方式更节省信令开销。
在一些实施例中,针对上述测量参考信号配置按照PCI粒度配置(不论属于上述直接关联还是间接关联),这些PCI信息对应的频点默认与终端设备服务小区频点相同。
·测量参考信号配置按照频点和PCI组合粒度配置;
在一些实施例中,按照频点和PCI组合粒度的配置方式与上述表4至表7的配置方式类似,也包括两种可能含义:直接关联方式(类似于表4和表5形式)和间接关联方式(类似于表6和表7形式),只是将表4至表7中的PCI标识替换成频点标识和PCI标识组合;或者,将PCI标识列表替换成频点标识和PCI标识组合列表。
可选地,针对上述测量参考信号配置按照频点和PCI组合粒度配置(不论属于上述直接关联还是间接关联),上述频点标识对应的频点为服务小区对应的频点或者为与服务小区对应频点不同的异频频点。
可选的,测量参考信号配置包括服务小区对应频点的同频邻区对应的测量参考信号配置;
可选的,测量参考信号配置包括与服务小区对应频点不同的异频邻区对应的测量参考信号配置;
可选的,测量参考信号配置同时包括服务小区对应频点的同频邻区对应的测量参考信号配置,以及与服务小区对应频点不同的异频邻区对应的测量参考信号配置。
·测量参考信号配置按照小区粒度配置。
在一些实施例中,按照小区粒度的配置方式与上述表4至表7的配置方式类似,也包括两种可能含义:直接关联方式(类似于表4和表5形式)和间接关联方式(类似于表6和表7形式),只是将表4至表7中的PCI标识替换成小区标识;或者,将PCI标识列表替换成小区标识列表。
可选的,小区标识为小区逻辑标识,比如:小区标识通过serving cell index(服务小区标识)形式表示;或者,小区标识通过全球小区标识CGI形式表示。
综上所述,通过设置测量参考信号配置可按照PCI粒度配置,或频点和PCI组合粒度配置,或小区粒度配置,进一步提供了L1测量配置用于执行邻区L1测量的实现方式,通过L1测量快速实现邻区测量,保证了L1/L2切换机制的低时延测量需求。
图4示出了本申请一个示例性实施例提供的小区测量方法的流程图,以该方法由终端设备执行进行举例说明,该方法包括:

在一些实施例中,测量间隔配置的配置方式至少包括以下三种:
第一种可能的配置方式:邻区L1测量复用L3测量配置的测量间隔,也即邻区L1测量不独立配置L1测量间隔;
可选的,第一种可能的配置方式需要进一步解决L1测量和L3测量的测量间隔时间分配比例问题,即:L3测量配置的测量间隔中多少时间比例用于执行L1测量,多少时间比例用于执行L3测量。
第二种可能的配置方式:为邻区L1测量单独配置测量间隔配置,即:邻区L1测量使用的测量间隔配置与L3测量使用的测量间隔配置不同;
在一些实施例中,第二种可能的配置方式可能包括如下两种子配置方式:
子方式一:所有的邻区L1测量(包括SSB资源测量和/或CSI-RS资源测量)共用一套测量间隔配置;
可选地,测量间隔配置包括适用范围配置,虽然在子方式1下所有的邻区L1测量共用一套测量间隔配置,但是某些邻区L1测量(比如:同频邻区L1测量)不需要使用测量间隔,不需要参与测量间隔共享,所以通过适用范围配置来显性给出哪些邻区L1测量需要共用这一套测量间隔配置即可。
子方式二:为邻区L1测量配置多套L1测量间隔配置。
在一些实施例中,每一套L1测量间隔配置对应一组SSB资源测量和/或一组CSI-RS资源测量。
可选的,通过适用范围配置,显性给出每一套L1测量间隔配置与一组SSB资源和/或一组CSI-RS资源的对应关系。
可选的,通过L1测量间隔配置列表与SSB资源和/或CSI-RS资源配置列表之间的隐式映射关系,给出每一套L1测量间隔配置与一组SSB资源和/或一组CSI-RS资源的对应关系。示例性的,L1测量间隔配置列表中的第一套L1测量间隔配置(L1测量间隔配置列表第一个元素)与SSB资源和/或CSI-RS资源配置列表中的第一组SSB资源和/或第一组CSI-RS资源对应(SSB资源和/或CSI-RS资源配置列表中的第一个元素)。
第三种可能的配置方式:部分情况下使用L3测量配置的测量间隔,另一部分情况下不使用任何测量间隔,再一部分情况下使用之前的L1测量配置的测量间隔。
在一些实施例中,在一次配置过程中测量间隔配置不出现或者不配置的情况下,使用上次配置过程的测量间隔配置执行邻区L1测量,或者,使用L3测量配置中配置的测量间隔配置执行邻区L1测量。
在一些实施例中,在测量间隔配置处于去激活状态条件下,使用L3测量配置中配置的测量间隔配置执行邻区L1测量,或者不使用任何测量间隔配置执行邻区L1测量。
需要说明的是,本申请不排除测量间隔配置对应的适用范围配置不包含在测量间隔配置中的配置方式,即:适用范围配置与测量间隔配置通过两个参数独立并列配置。
基于上述第一种可能的配置方式和第三种可能的配置方式,在执行邻区L1测量时,可能使用L3测量配置中配置的测量间隔配置,因此,在一些实施例中,终端设备还获知L3测量的间隔共享配置。
可选的,L3测量的间隔共享配置包括如下信息中的至少一项:

在一些实施例中,终端设备通过默认方式,获知L3测量的间隔共享配置;或者,终端设备通过接收网络设备发送的终端专用信令,获知L3测量的间隔共享配置。可选的,默认方式可理解为协议预定义的方式。
在一些实施例中,步骤420之前或之后还包括:接收网络设备发送的第一指示信息,第一指示信息用于激活或者去激活测量间隔配置。可选的,第一指示信息携带在如下任意一种消息中:RRC消息、MAC CE消息或者DCI消息。
需要说明的是,步骤420中“执行邻区L1测量”可能被替换为“执行服务小区L1测量”,在这种情况下,“服务小区L1测量”包括服务小区L1测量和邻区L1测量,具体解释请参考步骤220对应部分描述,此处不再赘述。
综上所述,L1测量配置包括测量参考信号配置以及测量间隔配置,进一步提供了L1测量配置用于执行邻区L1测量的实现方式,通过L1测量快速实现邻区测量,保证了L1/L2切换机制的低时延测量需求。
图5示出了本申请一个示例性实施例提供的小区测量方法的流程图,以该方法由终端设备执行进行举例说明,该方法包括:

综上所述,L1测量配置包括测量参考信号配置、测量间隔配置以及L1测量共享配置,进一步提供了L1测量配置用于执行邻区L1测量的实现方式,通过L1测量快速实现邻区测量,保证了L1/L2切换机制的低时延测量需求。
图6示出了本申请一个示例性实施例提供的小区测量方法的流程图,该方法包括:
步骤610,向网络设备提供用于执行邻区L1测量的测量辅助信息;
在一些实施例中,测量辅助信息包括以下中的至少一种:
·小区标识,以及每个小区对应的L1测量的间隔需求指示信息;
·频点标识,以及每个频点对应的L1测量的间隔需求指示信息;
·SSB资源标识,以及每个SSB资源对应的L1测量的间隔需求指示信息;

可选的,第二指示信息可能通过如下消息类型中的任意一种携带:
·RRC消息;
·MAC CE消息;
·DCI消息。
步骤620,基于网络设备配置的测量参考信号配置和测量间隔配置,执行邻区L1测量;
需要说明的是,步骤620是上述步骤610后的可选步骤,在一种实现方式下,终端设备执行步骤610,随后接收网络设备向终端设备发送配置消息(包括测量参考信号配置和测量间隔配置),之后,终端设备执行步骤620。
在一些实施例中,测量参考信号配置包括待测量邻区的SSB资源对应的配置;或,测量参考信号配置包括待测量邻区的CSI-RS资源对应的配置;或,测量参考信号配置包括待测量邻区的SSB资源对应的配置和待测量邻区的CSI-RS资源对应的配置。关于测量参考信号配置的介绍在上述图3所示的实施例已详细说明,此处不再赘述。
在一些实施例中,测量间隔配置包括以下信息中的至少一种:

关于测量间隔配置的介绍在上述图4所示的实施例已详细说明,此处不再赘述。
需要说明的是,步骤620中“执行邻区L1测量”可能被替换为“执行服务小区L1测量”,在这种情况下,“服务小区L1测量”包括服务小区L1测量和邻区L1测量,具体解释请参考步骤220对应部分描述,此处不再赘述。
综上所述,通过向网络设备发送测量辅助信息,向网络设备发送测量间隔需求,并且,L1测量配置包括测量参考信号配置以及测量间隔配置,进一步提供了L1测量配置用于执行邻区L1测量的实现方式,通过L1测量快速实现邻区测量,保证了L1/L2切换机制的低时延测量需求。
基于上述图3-图6所示的可选实施例,在一些实施例中,邻区L1测量的对象包括:服务小区的至少一个同频邻区,和/或,服务小区的至少一个异频邻区。
在一种实现方式下,L1测量区分服务小区L1测量和邻区L1测量。
可选的,同频邻区或异频邻区和服务小区既可以是时间同步情形,也可能是时间异步情形。
针对时间异步情形,同频邻区的邻区L1测量的参考信号测量窗口(例如:SMTC配置)可以按照PCI粒度独立配置,即:与服务小区频点相同但对应PCI不同的邻区,允许单独配置一套邻区L1测量的参考信号测量窗口配置;或者,针对时间异步情形,同频邻区复用为服务小区频点配置的L1测量的参考信号测量窗口配置或者复用为服务小区频点配置的L3测量的参考信号测量窗口配置,该配置方式下,终端设备需要根据服务小区和同频邻区的绝对时间差值调整参考信号测量窗口的实际位置,以便实际测得异步同频邻区发送的测量参考信号。
在另一种可能的实现方式下,协议中将整个终端设备执行邻区L1测量的对象全部定义为对终端设备服务小区的L1测量,即:不论L1测量配置实际包含一个小区的L1测量配置还是包含至少两个小区(小区通过PCI+频点标识)的L1测量配置,终端设备都将全部的L1测量称作对服务小区的L1测量。示例性地,服务小区对应的标识为频点1和PCI1,同时服务小区有两个同频邻区,分别对应的标识为频点1和PCI2以及频点1和PCI3,服务小区L1测量配置同时包括对频点1和PCI1、频点1和PCI2以及频点1和PCI3的测量,此时,对上述三个小区的L1测量统称为对服务小区的L1测量;频点1和PCI2对应小区以及频点1和PCI3对应小区与频点1和PCI1对应的服务小区之间既可以是时间同步情形,也可能是时间异步情形。
综上所述,设置邻区L1测量的对象包括:服务小区的至少一个同频邻区,和/或,服务小区的至少一个异频邻区,进一步提供了L1测量配置用于执行邻区L1测量的实现方式,通过L1测量快速实现邻区测量,保证了L1/L2切换机制的低时延测量需求。
基于上述图3-图6所示的可选实施例,在一些实施例中,小区测量方法还包括:接收网络设备发送的第三指示信息,第三指示信息用于激活或者去激活终端设备的邻区L1测量的功能。
可选的,第三指示信息携带在如下消息中的任意一种:RRC消息、MAC CE消息或者DCI消息。
综上所述,设置第三指示信息用于激活或者去激活终端设备的邻区L1测量的功能,可以灵活控制邻区L1测量的执行,提高测量效率。
基于上述图3-图6所示的可选实施例,在一些实施例中,小区测量方法还包括:向网络设备发送能力指示信息;其中,能力指示信息用于指示终端设备是否具备执行邻区L1测量的能力,和/或,能力指示信息用于指示终端设备是否具备上报邻区L1测量的测量辅助信息的能力。
可选的,在上述两种功能(执行邻区L1测量的能力和上报测量辅助信息的能力)均被定义的情况下,两种能力可以分别采用各自的能力指示信息指示,也可以共用一个能力指示信息指示。在两种能力共用一个能力指示信息指示的情况下,邻区L1测量的功能和上报邻区L1测量辅助信息的功能同时被支持或者同时不被支持。
综上所述,设置能力指示信息用于指示终端设备是否具备执行邻区L1测量的能力,和/或,终端设备是否具备上报邻区L1测量的测量辅助信息的能力,网络设备可以灵活控制终端设备邻区L1测量功能的激活或者去激活,比如,对支持该能力的终端设备激活上述功能,而对不支持该能力的终端设备不激活上述功能。
在上述已详细介绍了终端设备基于L1测量配置,执行邻区L1测量的详细过程,接下来将介绍网络设备为终端设备配置L1测量配置的过程。
图7示出了本申请一个示例性实施例提供的小区测量方法的流程图,以该方法由网络设备执行进行举例说明,该方法包括:
步骤720,向终端设备发送L1测量配置,L1测量配置用于终端设备执行邻区L1测量。
在一些实施例中,网络设备为终端设备配置用于执行邻区L1测量的测量参考信号配置;
或者,网络设备为终端设备配置用于执行邻区L1测量的测量参考信号配置,以及用于执行邻区L1测量的测量间隔配置;
或者,网络设备为终端设备配置用于执行邻区L1测量的测量参考信号配置、用于执行邻区L1测量的测量间隔配置,以及用于执行邻区L1测量的L1测量间隔共享配置。
在一些实施例中,网络设备通过如下消息中的任意一种,为终端设备配置用于执行服务小区测量和/或邻区L1测量的L1测量配置。
·RRC消息;
·***广播消息;
·MAC CE消息;
·DCI消息。
在一些实施例中,网络设备通过如下消息中的任意一种,为终端设备进行配置添加或进行配置更新或进行配置删除或进行配置去激活操作:
·RRC消息;
·***广播消息;
·MAC CE消息;
·DCI消息。
需要说明的是,步骤720中“执行邻区L1测量”可能被替换为“执行服务小区L1测量”,在这种情况下,“服务小区L1测量”包括服务小区L1测量和邻区L1测量,因为,在执行L1测量任务时,网络设备将服务小区L1测量的相关配置和邻区L1测量的相关配置发送至终端设备,而终端设备可能并不区分对服务小区的测量和对邻区的测量。示例性的,网络设备将频点1和PCI 1的服务小区、频点1和PCI 2的邻区以及频点1和PCI 3的邻区的L1测量相关配置发送至终端设备,终端设备执行对上述小区的L1测量。一种定义规则下,服务小区L1测量只包括对频点1和PCI 1对应小区的L1测量,而对频点1和PCI 2对应小区以及频点1和PCI 3对应小区的L1测量则称为邻区L1测量;在另外一种定义规则下,同时将对频点1和PCI 1对应小区的L1测量和对频点1和PCI 2对应小区以及频点1和PCI 3对应小区的L1测量统称为广义上的“服务小区L1测量”,本申请对上述定义规则不作限定。
综上所述,网络设备为终端设备配置L1测量配置,使得终端设备基于L1测量配置,可执行邻区L1测量,扩展了L1测量的使用范围,相比于L3测量机制,L1测量机制降低了频繁切换场景下的终端设备的服务中断时延。
图8示出了本申请一个示例性实施例提供的小区测量方法的流程图,以该方法由网络设备执行进行举例说明,该方法包括:
步骤820,向终端设备发送用于执行邻区L1测量的测量参考信号配置;
在一些实施例中,测量参考信号包括SSB,所述测量参考信号配置包括待测量邻区的SSB资源对应的配置;或,
测量参考信号包括CSI-RS,测量参考信号配置包括待测量邻区的CSI-RS资源对应的配置;或,

·参考信号测量窗口出现的周期;
·参考信号测量窗口出现的周期内偏移量;
·参考信号测量窗口的持续时长;
·参考信号测量窗口关联的时间参考小区对应的小区标识信息。
由于参考信号测量窗口配置对应的时域测量窗口是一个相对时间窗口,需要确定一个基准时间才能工作,而在一般情况下,参考信号测量窗口配置对应的基准时间为服务小区时间,此时,参考信号测量窗口关联的时间参考小区对应的小区标识信息不出现或者不配置,就表明该参考信号测量窗口默认以服务小区时间为基准时间;但如果参考信号测量窗口对应的基准时间不是服务小区,就需要通过参考信号测量窗口关联的时间参考小区对应的小区标识信息显性指出该参考信号测量窗口到底是以哪个小区的时间为基准时间。
在一些实施例中,参考信号测量窗口配置包括以下中的至少一种:
·第一周期相对于第二周期的偏差值,第一周期是L1测量配置中参考信号测量窗口出现的周期,第二周期是L3测量配置中对应频点关联的MO中的SMTC配置中对应的周期;

·第一持续时长相对于第二持续时长的偏差值,第一持续时长是L1测量配置中参考信号测量窗口的持续时长,第二持续时长是L3测量配置中对应频点关联的MO中的SMTC配置中对应的参考信号测量窗口的持续时长。
在一些实施例中,待测量邻区的CSI-RS资源对应的配置,包括以下中的至少一种:
·待测量邻区的小区标识;
·待测量邻区的至少一个CSI-RS资源对应的逻辑标识;
·待测量邻区的至少一个CSI-RS资源对应的时域资源配置;
·待测量邻区的至少一个CSI-RS资源对应的频域资源配置;
·待测量邻区的至少一个CSI-RS资源关联的准共址QCL参考信号配置。
