请参考图1，其示出了本公开实施例提供的一种无线通信系统的结构示意图。如图1所示，无线通信系统是基于蜂窝移动通信技术的通信系统，该无线通信系统可以包括：若干个终端11以及若干个基站12。
其中，终端11可以是指向用户提供语音和/或数据连通性的设备。终端11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11可以是物联网终端，如传感器设备、移动电话(或称为“蜂窝”电话)和具有物联网终端的计算机，例如，可以是固定式、便携式、袖珍式、手持式、计算机内置的或者车载的装置。例如，站(Station，STA)、订户单元(subscriber unit)、订户站(subscriber station)、移动站(mobile station)、移动台(mobile)、远程站(remote station)、接入点、远程终端(remote terminal)、接入终端(access terminal)、用户装置(user terminal)、用户代理(user agent)、用户设备(user device)、或用户终端(user equipment，UE)。或者，终端11也可以是无人飞行器的设备。或者，终端11也可以是车载设备，比如，可以是具有无线通信功能的行车电脑，或者是外接行车电脑的无线通信设备。或者，终端11也可以是路边设备，比如，可以是具有无线通信功能的路灯、信号灯或者其它路边设备等。
基站12可以是无线通信系统中的网络侧设备。其中，该无线通信系统可以是第四代移动通信技术(the 4th generation mobile communication，4G)系统，又称长期演进(Long Term Evolution，LTE)系统；或者，该无线通信系统也可以是5G系统，又称新空口(new radio，NR)系统或5G NR系统。或者，该无线通信系统也可以是5G系统的再下一代系统。其中，5G 系统中的接入网可以称为NG-RAN(New Generation-Radio Access Network，新一代无线接入网)。或者，MTC系统。
其中，基站12可以是4G系统中采用的演进型基站(eNB)。或者，基站12也可以是5G系统中采用集中分布式架构的基站(gNB)。当基站12采用集中分布式架构时，通常包括集中单元(central unit，CU)和至少两个分布单元(distributed unit，DU)。集中单元中设置有分组数据汇聚协议(Packet Data Convergence Protocol，PDCP)层、无线链路层控制协议(Radio Link Control，RLC)层、媒体访问控制(Media Access Control，MAC)层的协议栈；分布单元中设置有物理(Physical，PHY)层协议栈，本公开实施例对基站12的具体实现方式不加以限定。
基站12和终端11之间可以通过无线空口建立无线连接。在不同的实施方式中，该无线空口是基于第四代移动通信网络技术(4G)标准的无线空口；或者，该无线空口是基于第五代移动通信网络技术(5G)标准的无线空口，比如该无线空口是新空口；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。
在一些实施例中，终端11之间还可以建立E2E(End to End，端到端)连接。比如车联网通信(vehicle to everything，V2X)中的V2V(vehicle to vehicle，车对车)通信、V2I(vehicle to Infrastructure，车对路边设备)通信和V2P(vehicle to pedestrian，车对人)通信等场景。
在一些实施例中，上述无线通信系统还可以包含网络管理设备13。
若干个基站12分别与网络管理设备13相连。其中，网络管理设备13可以是无线通信系统中的核心网设备，比如，该网络管理设备13可以是演进的数据分组核心网(Evolved Packet Core，EPC)中的移动性管理实体(Mobility Management Entity，MME)。或者，该网络管理设备也可以是其它的核心网设备，比如服务网关(Serving GateWay，SGW)、公用数据网网 关(Public Data Network GateWay，PGW)、策略与计费规则功能单元(Policy and Charging Rules Function，PCRF)或者归属签约用户服务器(Home Subscriber Server，HSS)等。对于网络管理设备13的实现形态，本公开实施例不做限定。
本公开实施例涉及的执行主体包括但不限于：支持蜂窝移动通信的手机终端等UE，以及基站等。
本公开实施例的一个应用场景为，NR系统可以引入多载波服务小区，如图2所示，多载波服务小区由多个载波，如CC1，CC2和CC3组成，其中CC1为主载波，CC2和CC3为辅载波。UE只能通过主载波CC1获取系统消息和接收寻呼(paging)，并且可以在所有载波上做无线资源管理(RRM，Radio Resource Management)测量和发起物理随机接入信道(PRACH，Physical Random Access Channel)接入。当服务小区为FR2小区时，根据现有方案，UE在RRC空闲态(idle)态需要驻留在FR2小区，这样比较费电，如果通过配置一个多载波服务小区(1个FR1载波和2个FR2载波)，UE在idle态可以驻留在FR1载波，如果有业务，UE在发起PRACH，直接回到FR2载波进行数据收发。这样可以达到基站省电的效果。因此有必要研究终端UE在多载波服务小区场景下的小区重选配置方法。
相关技术中，服务小区只包括一个载波，UE只需要根据该载波的无线信号测量值与该载波的重选门限的比较结果，可以确定是否进行小区重选。多载波小区包括多个载波，UE在多载波小区如何确定是否需要进行小区重选是亟待解决的问题。
如图3所示，本示例性实施例提供一种小区重选配置方法，小区重选配置方法可以应用于多载波小区的接入网设备中，包括：
步骤301：发送所述多载波小区的重选配置信息，其中，所述重选配置信息，至少指示：UE进行小区重选的至少一个重选门限值。
这里，UE可以是采用蜂窝移动通信技术进行无线通信的手机UE等。多载波小区可以是UE当前的服务小区。多载波小区可以包括多个载波，包括主载波和辅载波。UE只可以通过主载波获取系统消息、接收寻呼，并且UE可以在所有载波上进行RRM测量和发起PRACH接入。接入网设备可以是在蜂窝移动通信系统中，向UE提供接入网接口的基站等。
接入网设备可以向UE发送重选配置信息指示至少一个重选门限值。重选门限值可以是针对一个载波的重选门限值，也可以是针对多个载波的重选门限值，还可以是分别针对每个载波的重选门限值。其中，UE可以是处于RRC空闲态或RRC非激活态的UE，也可以是处于连接态的UE。
重选门限值可以是用于指示载波信号质量的门限值。当载波的无线信号测量值小于重选门限值，可以说明载波的信号质量不能满足当前通信的要求。重选门限值可以包括信号强度门限值、信噪比门限值等；相应的无线信号测量值可以包括信号强值、信噪比值等。
UE可以基于接收重选门限值所针对的载波进行小区重选的确定。例如，当只接收到一个载波的重选门限值时，如果该载波的无线信号测量值小于重选门限值时，进行小区重选，否则，不进行小区重选，继续驻留在当前服务小区。
在一个实施例中，接入网设备可以将重选配置信息携带在系统消息中发送给UE。例如，接入网设备可以将重选配置信息携带在系统消息块(SIB，System Information Block)中发送给UE。
UE可以确定需要将无线信号测量值与重选门限值进行比较的载波，并进行无线信号测量。
在一个实施例中，所述重选门限值,包括：参考信号接收功率(RSRP，Reference Signal Receiving Power)门限值和/或参考信号接收质量(RSRQ，Reference Signal Receiving Quality)门限值。
UE进行无线信号测量得到的无线信号测量值可以包括：RSRP和/或RSRQ。可以将RSRP与RSRP门限值进行比较，和/或将RSRQ与RSRQ门限值进行比较。
如此，针对多载波小区，接入网设备可以发送指示至少一个重选门限值的重选配置信息，UE可以基于确定的至少一个重选门限值进行小区重选的确定。接入网设备可以通过发送不同重选门限值灵活地向UE指示进行小区重选的判定条件，提高小区重选的灵活性，进而实现多载波小区的小区重选，满足蜂窝移动通信的需求。
在一个实施例中，所述重选配置信息，指示内容包括以下至少之一：
多个所述重选门限值，不同的所述重选门限值为所述多载波小区内不同载波的重选门限值；
一个所述重选门限值，其中，一个所述重选门限值为所述多载波小区内不同载波共同对应的重选门限值。
多载波小区可以包括一个主载波和至少一个辅载波。这里，重选配置信息指示的多个所述重选门限值可以包括：一个主载波的无线信号测量值和至少一个辅载波的无线信号测量值分别对应的重选门限值等。例如。重选配置信息指示的多个所述重选门限值可以包括：多载波小区内所有载波分别对应的重选门限值。重选配置信息指示的多个所述重选门限值可以包括：多个预定载波的无线信号测量值分别对应的重选门限值等，例如，所有辅载波分别对应的重选门限值。
示例性的，重选配置信息指示的多个所述重选门限值可以包括：一个主载波的无线信号测量值和至少一个辅载波的无线信号测量值分别对应的重选门限值。例如，重选配置信息指示多个所述重选门限值R0，R1,…Ri，其中R0对应主载波f0，即锚点频率载波(Anchor frequency carrier)的重选门限值，R1对应辅载波f1，即非锚点频率载波(Non-Anchor frequency  carrier)的门限值，Ri对应辅载波fi的重选门限值；这里，重选门限值可以是RSRP门限值或RSRQ门限值等。
UE可以基于从多载波小区内不同载波共同对应的重选门限值中选择一个或多个重选门限值与对应的载波的无线信号测量值进行比较，进而确定是否进行小区重选。
在一个实施例中，UE响应于所述重选配置信息指示多个所述重选门限值，并且各所述载波的无线信号测量值，分别小于各所述载波的所述重选门限值，进行所述小区重选。
示例性的，重选配置信息指示的多个所述重选门限值可以包括：多载波小区内所有载波分别对应的重选门限值。UE可以对多载波小区内每个载波进行无线信号的测量，并将每个载波的无线信号测量值与对应的重选门限值进行比较，如果每个载波的无线信号测量值均小于对应的重选门限值，则说明各载波均不能满足通信的需求，需要进行小区重选。
例如，UE在所有载波上的无线信号测量值(RSRP或RSRQ)都低于对应的配置门限值R0，R1，…Ri；UE可以进行小区重选。
如此，UE比较不同载波的无线信号测量值与对应的重选门限值，确定是否进行小区重选，实现对多载波小区内多个载波的评估，提高多载波小区小区重选的可靠性。
在一个实施例中，UE响应于所述重选配置信息指示多个所述重选门限值，并且至少一个所述载波的无线信号测量值，大于或等于对应的所述重选门限值，驻留在当前服务小区，不进行所述小区重选。
如果至少一个载波的无线信号测量值均大于或等于对应的重选门限值，则说明当前服务小区中，仍然有载波均能满足通信的需求，UE可以驻留在当前的服务区。
在一个实施例中，所述多载波小区内不同载波的重选门限值，至少包 括：所述多载波小区内主载波的重选门限值。
示例性的，UE可以只多载波小区内的主载波进行无线信号的测量，并将主载波的无线信号测量值与主载波的重选门限值进行比较，如果主载波的无线信号测量值小于对应的重选门限值，则可以确定主载波不能满足获取系统消息、接收寻呼等通信的需求，需要进行小区重选。
如果主载波的无线信号测量值均大于或等于对应的重选门限值，则可以确定主载波能满足获取系统消息、接收寻呼等通信的需求，可以驻留在当前的服务小区。
由于主载波承载系统消息、寻呼消息等，因此，主载波在通信中起到决定性作用，如果主载波不满足通信需求，UE和基站无法实现完整的通信流程。通过主载波确定是否进行小区重选，由于UE只对一个载波的无线信号测量值与对应的重选门限值比较，提高了小区重选评估的效率。
重选配置信息指示的一个所述重选门限值可以包括：载波小区内各载波共同对应的重选门限值。UE可以将各载波的无线信号测量值可以分别与该重选门限值进行比较；或者可以将各载波的无线信号测量值的统计值，如加权平均值等与该重选门限值进行比较。
在一个实施例中，所述多载波小区内不同载波共同对应的重选门限值，包括：不同所述载波的无线信号测量值的平均值对应的重选门限值。
示例性的，UE可以只多载波小区内各载波进行无线信号的测量，并确定各载波的无线信号测量值的平均值，进而将该平均值与平均值对应的重选门限值进行比较，如果平均值小于对应的重选门限值，则可以确定当前服务小区的信号质量不佳，可以进行小区重选。
如果平均值大于或等于对应的重选门限值，则可以确定当前服务小区的信号质量可以满足通信需求，可以不进行小区重选，驻留在当前的服务小区。
通过比较各载波的无线信号测量值的平均值与对应的重选门限值确定是否进行小区重选，减少对比的重选门限值数量，提高了小区重选评估的效率。
如图4所示，本示例性实施例提供一种信息传输方法，信息传输方法可以应用于UE中，包括：
步骤401：接收多载波小区的重选配置信息，其中，所述重选配置信息，至少指示：UE进行小区重选的至少一个重选门限值。
这里，UE可以是采用蜂窝移动通信技术进行无线通信的手机UE等。多载波小区可以是UE当前的服务小区。多载波小区可以包括多个载波，包括主载波和辅载波。UE只可以通过主载波获取系统消息、接收寻呼，并且UE可以在所有载波上进行RRM测量和发起PRACH接入。接入网设备可以是在蜂窝移动通信系统中，向UE提供接入网接口的基站等。
接入网设备可以向UE发送重选配置信息指示至少一个重选门限值。重选门限值可以是针对一个载波的重选门限值，也可以是针对多个载波的重选门限值，还可以是分别针对每个载波的重选门限值。其中，UE可以是处于RRC空闲态或RRC非激活态的UE，也可以是处于连接态的UE。
重选门限值可以是用于指示载波信号质量的门限值。当载波的无线信号测量值小于重选门限值，可以说明载波的信号质量不能满足当前通信的要求。重选门限值可以包括信号强度门限值、信噪比门限值等；相应的无线信号测量值可以包括信号强值、信噪比值等。
UE可以基于接收重选门限值所针对的载波进行小区重选的确定。例如，当只接收到一个载波的重选门限值时，如果该载波的无线信号测量值小于重选门限值时，进行小区重选，否则，不进行小区重选，继续驻留在当前服务小区。
在一个实施例中，接入网设备可以将重选配置信息携带在系统消息中 发送给UE。例如，接入网设备可以将重选配置信息携带在系统消息块(SIB，System Information Block)中发送给UE。
UE可以确定需要将无线信号测量值与重选门限值进行比较的载波，并进行无线信号测量。
在一个实施例中，所述重选门限值,包括：参考信号接收功率RSRP门限值和/或参考信号接收质量RSRQ门限值。
UE进行无线信号测量得到的无线信号测量值可以包括：RSRP和/或RSRQ。可以将RSRP与RSRP门限值进行比较，和/或将RSRQ与RSRQ门限值进行比较。
如此，针对多载波小区，接入网设备可以发送指示至少一个重选门限值的重选配置信息，UE可以基于确定的至少一个重选门限值进行小区重选的确定。接入网设备可以通过发送不同重选门限值灵活地向UE指示进行小区重选的判定条件，提高小区重选的灵活性，进而实现多载波小区的小区重选，满足蜂窝移动通信的需求。
在一个实施例中，所述重选配置信息，指示内容包括以下至少之一：
多个所述重选门限值，不同的所述重选门限值为所述多载波小区内不同载波的重选门限值；
一个所述重选门限值，其中，一个所述重选门限值为所述多载波小区内不同载波共同对应的重选门限值。
多载波小区可以包括一个主载波和至少一个辅载波。这里，重选配置信息指示的多个所述重选门限值可以包括：一个主载波的无线信号测量值和至少一个辅载波的无线信号测量值分别对应的重选门限值等。例如。重选配置信息指示的多个所述重选门限值可以包括：多载波小区内所有载波分别对应的重选门限值。重选配置信息指示的多个所述重选门限值可以包括：多个预定载波的无线信号测量值分别对应的重选门限值等，例如，所 有辅载波分别对应的重选门限值。
示例性的，重选配置信息指示的多个所述重选门限值可以包括：一个主载波的无线信号测量值和至少一个辅载波的无线信号测量值分别对应的重选门限值。例如，重选配置信息指示多个所述重选门限值R0，R1,…Ri，其中R0对应主载波f0，即锚点频率载波(Anchor frequency carrier)的重选门限值，R1对应辅载波f1，即非锚点频率载波(Non-Anchor frequency carrier)的门限值，Ri对应辅载波fi的重选门限值；这里，重选门限值可以是RSRP门限值或RSRQ门限值等。
在一个实施例中，所述方法还包括：基于所述多载波小区的无线信号测量值与所述重选门限值的比较结果，进行小区重选。
UE可以基于从多载波小区内不同载波共同对应的重选门限值中选择一个或多个重选门限值与对应的载波的无线信号测量值进行比较，进而确定是否进行小区重选。
在一个实施例中，所述基于所述多载波小区的无线信号测量值，与所述重选门限值的比较结果，进行小区重选，包括：
响应于所述重选配置信息指示多个所述重选门限值，并且各所述载波的无线信号测量值，分别小于各所述载波的所述重选门限值，进行所述小区重选。
示例性的，重选配置信息指示的多个所述重选门限值可以包括：多载波小区内所有载波分别对应的重选门限值。UE可以对多载波小区内每个载波进行无线信号的测量，并将每个载波的无线信号测量值与对应的重选门限值进行比较，如果每个载波的无线信号测量值均小于对应的重选门限值，则说明各载波均不能满足通信的需求，需要进行小区重选。
例如，UE在所有载波上的无线信号测量值(RSRP或RSRQ)都低于对应的配置门限值R0，R1，…Ri；UE可以进行小区重选。
如此，UE比较不同载波的无线信号测量值与对应的重选门限值，确定是否进行小区重选，实现对多载波小区内多个载波的评估，提高多载波小区小区重选的可靠性。
在一个实施例中，UE响应于所述重选配置信息指示多个所述重选门限值，并且至少一个所述载波的无线信号测量值，大于或等于对应的所述重选门限值，驻留在当前服务小区，不进行所述小区重选。
如果至少一个载波的无线信号测量值均大于或等于对应的重选门限值，则说明当前服务小区中，仍然有载波均能满足通信的需求，UE可以驻留在当前的服务区。
在一个实施例中，所述多载波小区内不同载波的重选门限值，至少包括：所述多载波小区内主载波的重选门限值。
在一个实施例中，所述基于所述多载波小区的无线信号测量值，与所述重选门限值的比较结果，进行小区重选，包括：
响应于所述重选配置信息指示的多个所述重选门限值，包括主载波的重选门限值，并且所述主载波的无线信号测量值，小于所述主载波的所述重选门限值，进行所述小区重选。
示例性的，UE可以只多载波小区内的主载波进行无线信号的测量，并将主载波的无线信号测量值与主载波的重选门限值进行比较，如果主载波的无线信号测量值小于对应的重选门限值，则可以确定主载波不能满足获取系统消息、接收寻呼等通信的需求，需要进行小区重选。
如果主载波的无线信号测量值均大于或等于对应的重选门限值，则可以确定主载波能满足获取系统消息、接收寻呼等通信的需求，可以驻留在当前的服务小区。
由于主载波承载系统消息、寻呼消息等，因此，主载波在通信中起到决定性作用，如果主载波不满足通信需求，UE和基站无法实现完整的通信 流程。通过主载波确定是否进行小区重选，由于UE只对一个载波的无线信号测量值与对应的重选门限值比较，提高了小区重选评估的效率。
重选配置信息指示的一个所述重选门限值可以包括：载波小区内各载波共同对应的重选门限值。UE可以将各载波的无线信号测量值可以分别与该重选门限值进行比较；或者可以将各载波的无线信号测量值的统计值，如加权平均值等与该重选门限值进行比较，根据比较结果，确定是否进行小区重选。
在一个实施例中，所述多载波小区内不同载波共同对应的重选门限值，包括：不同所述载波的无线信号测量值的平均值对应的重选门限值。
在一个实施例中，所述基于所述多载波小区的无线信号测量值，与所述重选门限值的比较结果，进行小区重选，包括：
响应于所述重选配置信息指示不同所述载波的无线信号测量值的平均值对应的重选门限值，并且所述不同所述载波的无线信号测量值的平均值，小于所述重选门限值，进行所述小区重选。
示例性的，UE可以只多载波小区内各载波进行无线信号的测量，并确定各载波的无线信号测量值的平均值，进而将该平均值与平均值对应的重选门限值进行比较，如果平均值小于对应的重选门限值，则可以确定当前服务小区的信号质量不佳，可以进行小区重选。
如果平均值大于或等于对应的重选门限值，则可以确定当前服务小区的信号质量可以满足通信需求，可以不进行小区重选，驻留在当前的服务小区。
通过比较各载波的无线信号测量值的平均值与对应的重选门限值确定是否进行小区重选，减少对比的重选门限值数量，提高了小区重选评估的效率。
以下结合上述任意实施例提供一个具体示例：
1、服务小区通过SIB系统消息配置小区重选门限值，有以下方式配置小区重选门限值：
配置方式1：配置多个小区重选门限值R0，R1,…Ri,其中R0对应主载波f0，即锚点频率载波(Anchor frequency carrier)的重选门限值，R1对应辅载波f1，即非锚点频率载波(Non-Anchor frequency carrier)的重选门限值，Ri对应辅载波fi的重选门限值。
