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清楚描述,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所获得的所有其他实施例,都属于本申请保护的范围。
本申请的说明书和权利要求书中的术语“第一”、“第二”等是用于区别类似的对象,而不用于描述特定的顺序或先后次序。应该理解这样使用的术语在适当情况下可以互换,以便本申请的实施例能够以除了在这里图示或描述的那些以外的顺序实施,且“第一”、“第二”所区别的对象通常为一类,并不限定对象的个数,例如第一对象可以是一个,也可以是多个。此外,说明书以及权利要求中“和/或”表示所连接对象的至少其中之一,字符“/”一般表示前后关联对象是一种“或”的关系。
值得指出的是,本申请实施例所描述的技术不限于长期演进型(Long Term Evolution,LTE)/LTE的演进(LTE-Advanced,LTE-A)系统,还可用于其他无线通信系统,诸如码分多址(Code Division Multiple Access,CDMA)、时分多址(Time Division Multiple Access,TDMA)、频分多址(Frequency Division Multiple Access,FDMA)、正交频分多址(Orthogonal Frequency Division Multiple Access,OFDMA)、单载波频分多址(Single-carrier Frequency-Division Multiple Access,SC-FDMA)和其他系统。本申请实施例中的术语“系统”和“网络”常被可互换地使用,所描述的技术既可用于以上提及的系统和 无线电技术,也可用于其他系统和无线电技术。以下描述出于示例目的描述了新空口(New Radio,NR)系统,并且在以下大部分描述中使用NR术语,但是这些技术也可应用于NR系统应用以外的应用,如第6代(6 th Generation,6G)通信系统。
图2示出本申请实施例可应用的一种无线通信系统的结构图。无线通信系统包括终端11和网络侧设备12。其中,终端11也可以称作终端设备或者用户终端(User Equipment,UE),终端11可以是手机、平板电脑(Tablet Personal Computer)、膝上型电脑(Laptop Computer)或称为笔记本电脑、个人数字助理(Personal Digital Assistant,PDA)、掌上电脑、上网本、超级移动个人计算机(ultra-mobile personal computer,UMPC)、移动上网装置(Mobile Internet Device,MID)、增强现实(augmented reality,AR)/虚拟现实(virtual reality,VR)设备、机器人、可穿戴式设备(Wearable Device)、车载设备(VUE)、行人终端(PUE)、智能家居(具有无线通信功能的家居设备,如冰箱、电视、洗衣机或者家具等)等终端侧设备,可穿戴式设备包括:智能手表、智能手环、智能耳机、智能眼镜、智能首饰(智能手镯、智能手链、智能戒指、智能项链、智能脚镯、智能脚链等)、智能腕带、智能服装、游戏机等。需要说明的是,在本申请实施例并不限定终端11的具体类型。网络侧设备12可以是基站或核心网,其中,基站可被称为节点B、演进节点B、接入点、基收发机站(Base Transceiver Station,BTS)、无线电基站、无线电收发机、基本服务集(Basic Service Set,BSS)、扩展服务集(Extended Service Set,ESS)、B节点、演进型B节点(eNB)、家用B节点、家用演进型B节点、WLAN接入点、WiFi节点、发送接收点(Transmitting Receiving Point,TRP)或所述领域中其他某个合适的术语,只要达到相同的技术效果,所述基站不限于特定技术词汇,需要说明的是,在本申请实施例中仅以NR系统中的基站为例,但是并不限定基站的具体类型。
在一实施例中,本申请实施例的方法可以应用于另一种无线通信系统中,该无线通信系统包括终端、辅助设备和网络侧设备,其中,辅助设备包括:RIS设备或者中继设备,可选地,中继设备可以是具有波束赋形功能的层一(Layer 1,L1)中继(relay/repeator)。
基于RIS设备的辅助设备的工作原理和工作特点如下:
RIS设备是由前端的人造表面和后端的控制模块组成。前端的人造表面由紧密均匀排列的人造器件单元构成;器件单元的电磁特性受到器件的控制信号/偏置电压影响,不同的控制信号/偏置电压对应于不同的反射系数/折射系数;反射系数/折射系数的变化会影响反射信号/折射信号的相位和/或强度;微观上每个器件单元导致独立的反射/折射信号,宏观上这些信号叠加在一起进而实现对电磁波的操控。控制信号/偏置电压由后端的控制模块提供。
RIS设备可以用于热点流量增强或覆盖空洞补盲的场景。
未来的无线业务会出现极大流量的数据业务(例如AR/VR,高清视频等),或者其他对无线信道要求很高的热点业务。如图3所示,针对于热点用户的热点需求,服务小区动态地激活辅助设备(例如收发节点TRP、RIS设备),从而增加热点用户的可用波束,满足热点业务需求。
小区覆盖范围内的障碍物导致覆盖空洞或者在小区边缘由于大尺度衰落和邻区信号干扰,导致无线信号在空洞区域或小区边缘区域强度弱/SINR低,通信质量受到影响;这种现象在高频波段/毫米波段更加常见。如图4所示,RIS设备是独立于基站的设备,可以部署在远离基站的可视位置,转发/反射基站的信号为覆盖空洞或者小区边缘区域提供通信服务。通过合理的节点部署,RIS设备避免被遮挡物遮挡,保证良好的信号覆盖。
智能表面RIS设备可以影响周围无线信号传播环境的能力。智能表面RIS设备在产生不同方向的波束的同时,对反射信号的能量分布造成影响,改变了无线环境中多径的能量和相位分布情况。当智能表面RIS 设备发生变化时,终端设备/网络设备的接收信号的信号强度和信道响应参数需要重新测量/估计。
RIS设备引起的信道变化与传统的信道变化的区别:a)RIS设备引起的信道变化是突变的,传统的信道变化是慢变的。RIS设备中器件的控制电压变化可以在纳秒ns~微秒us完成高低电平转换,而传统的无线信道变化速度或者信道时间相关性由周围传播环境的变化速度决定(包括终端的移动速度,反射/遮挡物体的移动速度),低速环境中无线信道是慢变的,时间相关性可达毫秒ms或更长。b)RIS设备引起的信道变化是周期性的,传统的信道变化是绝对随机的。RIS设备的变化以及RIS设备对附近信道环境的影响是受RIS设备的控制模块控制的,RIS设备可以周期地改变RIS反射参数。在慢变信道环境中,RIS设备的若干变化周期内信道环境的其他参数未发生变化,那么终端的接收信道响应将出现周期变化的特点。
在一实施例中,RIS设备或者L1中继部署于小区边缘用于增强小区边缘用户的信号质量。但是考虑到RIS设备或者L1中继不能自主生成数据信息,只能转发来自基站的信号,因此只有在基站向RIS设备发送信号或者RIS设备覆盖区域内终端向RIS设备发送上行信号时,RIS设备才能转发有效的信号,其他时间段内RIS设备为不工作状态,相应的RIS设备覆盖范围下的终端在RIS设备不工作的时间段内按照基站的指示处于休眠/静默状态或者直接与基站进行通信。
从基站调度方面考虑,基站需要保证与各个方向的终端的通信业务,因此只能在一部分时间段向RIS设备发送下行信号,或者接收RIS设备覆盖范围下的终端发送的上行信号。RIS设备在其他时间段可以转发其他小区对应基站的信号,从而为其他小区的边缘用户提供服务。在这种场景中,多个小区的交界区域的用户以时分复用的方式共享RIS设备提供的覆盖增强服务。
RIS设备共享给多个小区,即分别给不同小区的用户提供服务。在这 种部署场景中,RIS设备的覆盖范围是多个小区的过渡区域,实现用户的柔性小区切换,避免在用户信号质量太低时硬性小区切换。
多个基站共享使用RIS设备的时候,在终端侧观察到的多个基站的信号同时受到RIS设备转发波束影响。即指向终端的RIS波束可以用于转发基站1的信号,也可以在另一时间段用于转发基站2的信号。在终端看来,基站1和基站2的信号都是由RIS设备相同的波束转发,因此基站1和基站2的信号强度也相差不多。在上述场景下,由于辅助设备如RIS设备的引入使得小区交界区域的信号强度分布变得非常复杂,不再仅随基站距离远近变化,还受到RIS设备覆盖规划的影响,如何进行小区切换成为本领域技术人员亟待解决的问题。
本申请实施例的方案,网络侧设备根据共享使用辅助设备的第一服务小区和至少一个第一小区的测量结果,和/或,调度信息和/或终端的切换请求,调度小区切换。
下面结合附图,通过一些实施例及其应用场景对本申请实施例提供的小区切换方法进行详细地说明。

其中,第一信息包括以下至少一项:第一服务小区和至少一个第一小区的测量结果,和调度信息;第一小区为第一服务小区的邻小区,或终端的第二服务小区;第一服务小区和至少一个第一小区为共享使用辅助设备的小区。
其中,辅助设备可以被多个小区共享使用。可以理解,多个小区的网络侧设备按照时分或者空分复用的方式共享辅助设备。时分复用方式是指不同网络侧设备在不同时间段对辅助设备进行控制,辅助设备在对应的时间段内对相应网络侧设备的下行信号或者相应小区的终端的上行信号进行波束转发。空分复用方式是指不同网络侧设备在同一时间段内 以不同方向的波束向辅助设备发送信号,辅助设备将不同方向的入射信号转发到不同波束方向上实现不同小区信号的区分,为不同波束区域的终端提供信号,实现了最大化利用时间和空间资源,增强小区边缘区域的信号质量。
具体地,网络侧设备获取第一信息,第一信息可以包括:测量结果和/或调度信息,测量结果可以是对终端的第一服务小区和第一小区的测量结果,可选地,测量结果是终端上报给网络侧设备的。
调度信息可以包括以下至少一项:辅助设备覆盖范围内的终端数量、终端的业务信息或辅助设备的转发波束信息。其中,辅助设备的转发波束信息例如包括以下至少一项:转发波束对应的参考信号、端口号、服务小区、网络侧设备等信息。其中,终端的业务信息指的是辅助设备覆盖范围内的终端的业务信息。
可选地,终端可以具有多个服务小区,第一服务小区可以是终端的主服务小区,即主要的服务小区,第二服务小区可以是终端的从服务小区,即次要的服务小区。终端在该些第一服务小区和第二服务小区之间可以进行主从服务小区的切换。
可选地,终端还可以在服务小区和邻小区之间进行切换。
步骤102、网络侧设备根据第一信息调度小区切换。
具体地,网络侧设备根据第一信息调度小区切换,假设第一信息包括测量结果,根据测量结果调度小区切换,即比较不同小区的测量结果,若满足切换条件,则调度该终端进行小区切换,例如将终端从当前第一服务小区切换到目标小区,或进行主从小区切换,即将目标小区作为主服务小区,当前第一服务小区作为从服务小区。切换条件例如包括:待切换的目标小区的测量结果优于当前第一服务小区的测量结果,进一步还可以包括待切换的目标小区的测量结果与当前第一服务小区的测量结果之间的差值大于某个阈值,该阈值可以是预先设定的。
假设第一信息包括调度信息,网络侧设备根据调度信息,确定该终 端是否进行小区切换,例如当前服务小区的终端的数量较多,其他小区服务的终端的数量较少,可以将该终端从当前服务小区切换到其他小区。例如当前终端使用的业务为语音业务,当前服务小区使用该语音业务的终端的数量较多,可以将该终端切换到其他提供语音业务的小区。
网络侧设备也可以综合考虑测量结果和调度信息,进行小区切换的判断。
可选地,网络侧设备根据终端的切换请求,调度小区切换。终端可以基于不同小区的测量结果决定是否进行小区切换,若进行小区切换,则终端向网络侧设备发送切换请求,从而网络侧设备调度小区切换。
本实施例的方法,网络侧设备可以基于多个小区的测量结果和/或调度信息,为终端调度小区切换。所述多个小区共享使用辅助设备,多个小区包括:终端的第一服务小区和至少一个第一小区;其中,第一小区可以为第一服务小区的邻小区,或终端的第二服务小区,通过小区的测量结果和/或调度信息实现了在具有辅助设备的通信场景下终端进行小区切换的方案。
在一实施例中,第一信息包括终端的第一服务小区和至少一个第一小区的测量结果,步骤102具体可以通过如下方式实现:
网络侧设备根据第一服务小区和至少一个第一小区的测量结果,以及辅助设备的工作状态调度小区切换。
可以理解,辅助设备的工作状态包括工作状态和非工作状态。辅助设备处于工作状态,即辅助设备工作时,辅助设备转发网络侧设备的信号,或转发终端发送的上行信号。辅助设备处于非工作状态,即辅助设备不工作时,辅助设备不为任意一个网络侧设备转发信号。
所述多个小区的测量结果会受到辅助设备的工作状态的影响,网络侧设备在判断终端是否进行小区切换时,需要考虑辅助设备的工作状态。
可选地,步骤“网络侧设备根据第一服务小区和至少一个第一小区 的测量结果,以及辅助设备的工作状态调度小区切换”可以通过如下方式实现:
在辅助设备不工作的情况下,网络侧设备根据第一服务小区的测量结果和至少一个第一小区的测量结果,调度小区切换;
在辅助设备工作的情况下,网络侧设备根据终端的第一服务小区和至少一个第一小区在辅助设备转发的相同波束下的测量结果,调度小区切换。
具体地,辅助设备不工作时,可以测量多个小区的信号,即测量得到当前的第一服务小区的测量结果和第一小区的测量结果,此时所述小区的信号不受辅助设备转发波束的影响。
辅助设备不工作的时间段可以是由网络侧设备显式配置的时间窗口,或者根据辅助设备为各个小区服务的可用时间窗口隐式推导得出。该方案可以适用于第一小区的占用辅助设备的时间段和波束配置情况未知的场景。
辅助设备工作时,终端当前的第一服务小区和第一小区共享使用该辅助设备,因此该些小区的信号受到辅助设备转发波束的影响。测量结果为该些小区在辅助设备转发的相同波束下的测量结果。
例如,终端获取当前的第一服务小区在辅助设备转发的至少一个波束下的测量结果,例如为图1中的3个波束中至少一个波束,并获取第一小区在该辅助设备转发的至少一个波束下的测量结果,该第一小区对应的至少一个波束与第一服务小区对应的至少一个波束为相同的波束。例如,第一服务小区对应的至少一个波束为波束1,则第一小区对应的至少一个波束也为波束1。
对小区在至少一个波束下的测量结果进行处理,例如加权处理得到最终的测量结果,或选择其中某个波束对应的测量结果作为最终的测量结果。可选地,所述被选择的波束对应的测量结果可以是辅助设备转发的所有波束中测量波束中最好的测量结果。可选地,测量结果可以表示 为信干噪比(Signal to Interference Noise Ratio,SINR),或者参考信号接收功率(Reference Signal Received Power,RSRP),或者参考信号接收质量(Reference Signal Received Quality,RSRQ)。
可选地,辅助设备不工作时,在第二小区的测量结果与第一服务小区的测量结果的差值超过第一阈值的情况下,网络侧设备调度小区切换;
辅助设备工作时,在第二小区与第一服务小区在辅助设备转发的相同波束下的测量结果的差值超过第二阈值的情况下,网络侧设备调度小区切换;
其中,第二小区为至少一个第一小区中任一小区。
具体地,辅助设备不工作时,第二小区的测量结果与第一服务小区的测量结果的差值超过第一阈值,说明此时该第二小区的测量结果优于第一服务小区的测量结果,可以将该终端切换到该第二小区,或进行主从服务小区切换。
辅助设备工作时,第二小区与第一服务小区在辅助设备转发的相同波束下的测量结果的差值超过第二阈值,说明在辅助设备转发的相同波束下第二小区的测量结果优于第一服务小区的测量结果,因此可以将该终端切换到第二小区,或进行主从服务小区切换。
上述实施方式中,由于小区的信号受到辅助设备转发波束的影响,因此辅助设备的工作状态,影响小区的测量结果,根据小区的测量结果以及辅助设备的工作状态,调度小区切换,使得小区切换的决策更准确。
在一实施例中,步骤“网络侧设备根据第一服务小区和至少一个第一小区的测量结果,以及辅助设备的工作状态调度小区切换”可以通过如下几种方式实现:
在终端的服务小区包括第一服务小区和至少一个第二服务小区的情况下,网络侧设备根据第一服务小区和至少一个第二服务小区的测量结 果,以及辅助设备的工作状态调度主从服务小区切换;或,
在终端的服务小区仅包括第一服务小区的情况下,网络侧设备根据第一服务小区和至少一个邻小区的测量结果,以及辅助设备的工作状态调度小区切换。
具体地,对于终端同时可以与多个小区保持连接的场景,即终端同时接入多个小区,在该场景下终端具有多个服务小区,多个服务小区中具有一个主服务小区,和至少一个从服务小区。
终端将当前的主服务小区和从服务小区的测量结果,发送给网络侧设备,网络侧设备根据终端当前的主服务小区和从服务小区的测量结果,对终端的小区切换过程进行调度,调度时进一步考虑辅助设备的工作状态。
针对终端具有多个服务小区的场景,在所述辅助设备不工作的情况下,网络侧设备根据第一服务小区的测量结果和至少一个第二服务小区的测量结果,调度小区切换;
在辅助设备工作的情况下,网络侧设备根据终端的第一服务小区和至少一个第二服务小区在所述辅助设备转发的相同波束下的测量结果,调度小区切换。
对于终端不支持多小区同时接入的场景,终端将当前的第一服务小区和邻小区的测量结果,发送给网络侧设备,网络侧设备根据终端当前的第一服务小区和邻小区的测量结果,对终端的小区切换过程进行调度,进一步还需根据辅助设备的工作状态调度小区切换。
针对终端具有一个服务小区的场景,在辅助设备不工作的情况下,网络侧设备根据第一服务小区的测量结果和至少一个邻小区的测量结果,调度小区切换;
在辅助设备工作的情况下,网络侧设备根据终端的第一服务小区和至少一个邻小区在辅助设备转发的相同波束下的测量结果,调度小区切换。
该实施例中具体的调度方案可以参见前述实施例,此次不再赘述。
上述实施方式中,通过主从服务小区的切换,实现了小区软切换,能够保证通信业务的连续性,不影响终端的通信。
在一实施例中,调度信息包括辅助设备的转发波束信息,所述转发波束信息包括:转发波束对应的网络侧设备主从关系,步骤102可以通过如下方式实现:
在终端的服务小区包括第一服务小区和至少一个第二服务小区的情况下,网络侧设备根据终端的位置以及辅助设备的转发波束对应的网络侧设备主从关系,调度主从服务小区切换;转发波束对应的网络侧设备主从关系为根据辅助设备的转发波束的覆盖范围与各个服务小区对应的网络侧设备的相对位置确定的。
具体地,转发波束信息包括以下至少一项:转发的各个波束的标识,例如端口号;各个波束对应的参考信号;以及转发波束对应的服务小区和/或网络侧设备的信息。
可选地,转发波束对应的服务小区和/或网络侧设备的信息可以包括:转发波束对应的网络侧设备的主从关系。可选地,转发波束对应的网络侧设备的主从关系是根据辅助设备的转发波束的覆盖范围与各个服务小区对应的网络侧设备的相对位置确定的,例如转发波束与某个基站的距离较近,则将该基站作为主基站,其他基站作为从基站。
例如图1中,对于波束1来说,网络侧设备的主从关系为:基站1为主基站、基站2为从基站,对于波束2来说,网络侧设备的主从关系为:基站1为主基站,基站2为从基站,对于波束3来说,网络侧设备的主从关系为:基站2为主基站,基站1为从基站。若终端处于波束1的覆盖范围下,则将基站1作为主基站,将基站2作为从基站,在当前的第一服务小区为基站1覆盖下的小区,第二服务小区可以是基站2覆盖下的小区,若终端处于波束3的覆盖范围下,则将基站2作为主基站,基站1作为从基站,则需要进行主从服务小区的切换,当前第一服 务小区切换为从服务小区,第二服务小区中的一个小区切换为主服务小区,例如选择第二服务小区中信号质量最好的小区作为主服务小区。因此网络侧设备根据终端的位置变化以及转发波束对应的网络侧设备的主从关系,调度主从服务小区切换,例如终端从波束1的覆盖范围,移动到波束3的覆盖范围,则网络侧设备的主从关系发生变化,因此需要进行主从服务小区切换。
可选地,当终端从辅助设备的一个转发波束的覆盖范围切换到另一个转发波束的覆盖范围时,第一服务小区和第一小区对应的波束同时发生切换。
上述实施方式中,终端的具有多个服务小区时,网络侧设备根据终端的位置以及辅助设备的转发波束对应的网络侧设备主从关系,调度主从服务小区切换,实现过程简单,效率较高。
在一实施例中,网络侧设备根据第一信息,确定终端需要从当前的第一服务小区切换到第二小区;或将当前的第一服务小区切换为从服务小区,并将第二小区切换为主服务小区,该方法还包括如下步骤:
网络侧设备向所述终端发送切换指示消息,所述切换指示消息用于指示从所述第一服务小区切换到所述第二小区,或进行主从服务小区切换,切换指示消息指示了第二小区的配置信息,配置信息包括以下至少一项:第二小区的同步信号块(Synchronization Signal Block,SSB)的配置信息、系统信息(如系统信息块(System Information Block,SIB))、物理下行控制信道(Physical Downlink Control Channel,PDCCH)的配置信息,PDCCH的配置信息包括以下至少一项:PDCCH的发送周期、PDCCH的时频资源配置信息、PDCCH的使用波束。
具体地,网络侧设备在判断该终端需要进行小区切换后,网络侧设备向终端发送切换指示,切换指示用于指示从第一服务小区切换到第二小区,或,进行主从服务小区切换,即将当前的第一服务小区切换为从服务小区,第二小区切换为主服务小区。
其中,切换指示消息还包括切换的目标小区的信息,例如第二小区的SSB、SIB、PDCCH的发送周期、时频资源配置信息、使用波束等接收第二小区的广播信息的必要的配置参数。
可选地,切换指示消息包括的配置信息的生效时间可以在切换指示消息中显式指示,或者按照协议定义规则在接收到切换指示消息后固定时间开始生效。
可选地,网络侧设备还可以接收终端的切换请求,该切换请求是在终端获取第一服务小区和至少一个第一小区的测量结果之后发送的,即由终端确定是否需要进行小区切换,终端的确定是否需要进行小区切换的过程与网络侧设备的执行过程类似,此处不再赘述。
在一实施例中,步骤102之前还包括如下步骤:
网络侧设备根据辅助设备转发波束的测量结果,以及网络侧设备直接发送的波束的测量结果,确定终端处于辅助设备的覆盖范围。
具体的,网络侧设备为终端配置多个不同的监听波束,包含:网络侧设备直接发送的波束和经辅助设备转发的波束。终端对多个监听波束进行测量并上报测量结果,网络侧设备根据上报的测量结果判断终端是否进入辅助设备的覆盖范围,即终端是否使用辅助设备转发的波束进行通信。
可选地,不同的监听波束体现为不同的参考信号,配置为不同端口号、时频资源和伪随机序列。
在终端使用辅助设备的转发波束进行通信时,当前的第一服务小区对应的网络侧设备为终端配置辅助设备的服务小区和/或对应的网络侧设备以及相关配置信息。配置信息包括以下信息中的至少一种:共享辅助设备的服务小区的数量、物理小区标识PCI、各个服务小区使用辅助设备的使用时间、使用周期、各个服务小区的参考信号(SSB或者信道状态信息测量参考信号(Channel State Information Reference Signal,CSI-RS)的时频域配置参数。如果参考信号是CSI-RS,则还需要配置CSI- RS的生成序列的参数。
由于辅助设备的引入,两个小区的交界区域由原本的两个小区的基站发送单一波束的信号质量判断的区域(例如,基于RSRP判决,|RSRP_1-RSRP_2|>Thred,其中RSRP1表示基站1的信号质量,RSRP2表示基站2的信号质量,Thred为网络配置的小区切换门限。在小区交界区域,小区信号质量取决于该小区指向小区交界区域的波束的信号质量。满足上述触发条件才进行小区切换,否则驻留在原小区),变化为由多个波束(包括基站直接指向该区域的波束和辅助设备转发的波束)的信号质量判断的区域,原本的小区切换条件很难触发。因此在辅助设备覆盖的区域内同时存在多个小区的终端,导致小区边界进一步模糊,两个小区间的过渡区域进一步增大,导致受到邻区信号干扰的终端增多。因此,在一实施例中,终端可以同时接入多个小区,即终端具有多个服务小区,在该场景下,该方法还包括:
网络侧设备接收终端发送的第一服务小区和至少一个第三小区在辅助设备转发的相同波束下的测量结果;
网络侧设备根据测量结果,为终端配置至少一个第三小区的接入参数。
可选地,所述接入参数用于指示第一小区的PDSCH和PUSCH的数据参数,包括第一小区的DL/UL BWP相关配置参数,以及相关PDCCH和PUCCH配置参数。
具体地,网络侧设备根据终端的测量结果判断该终端是否与至少一个第三小区建立连接,或者根据网络侧设备的调度信息判断该终端是否与至少一个第三小区建立连接。
对于根据终端的测量结果判断的方案,至少一个第三小区的信号测量操作可以是网络侧设备发起的,或者终端根据事件触发的。当前的第一服务小区的网络侧设备为终端配置其他小区的测量参数,包括以下至少一项:参考信号(CSI-RS或者SSB并且指定SSB index)、测量周 期、测量窗口和测量次数,可以理解配置的参考信号为网络侧设备发送给辅助设备并由辅助设备转发的波束。其他小区的同一个SSB配置多个测量窗口,对应于辅助设备的多个转发波束。进一步可选地,可以包括辅助设备在不转发其他小区的信号或者辅助设备不工作时其他小区的参考信号的测量窗口。
对于网络侧设备调度的场景,终端上报辅助设备转发的同一个波束下多个小区的信号的测量结果,当前网络侧设备根据测量结果为终端配置其他小区的接入参数(例如,无竞争随机接入(contention free random access,CFRA)的前导序列preamble和随机接入信道机会(Random Access Channel Occasion,RO)资源)。
可选地,对于终端触发的场景,该方法还包括:
网络侧设备接收终端发送的连接建立请求,连接建立请求用于请求与至少一个第三小区建立连接;连接建立请求为在满足第一条件的情况下触发的,第一条件包括:第三小区在辅助设备转发的相同波束下的测量结果,与第一服务小区在辅助设备转发的相同波束下的测量结果之间的差值小于或等于第三阈值;
网络侧设备根据连接建立请求,为终端配置至少一个第三小区的接入参数。
具体地,终端在确定测量结果满足第一条件时触发向网络侧设备发送连接建立请求,用于请求与第三小区建立连接。
该第一条件包括:第三小区在辅助设备转发的相同波束下的测量结果,与第一服务小区在辅助设备转发的相同波束下的测量结果之间的差值小于或等于第三阈值,可以表示为如下公式:
abs(Ms-Mn)<Thresh,其中Ms表示当前第一服务小区在辅助设备转发的波束下的测量结果,Mn表示第一小区使用辅助设备的同一波束的测量结果,Thresh表示第一服务小区配置的第三阈值。
网络侧设备根据连接建立请求,为终端配置第一小区的接入参数, 具体可参见前述网络侧设备调度的场景。
可选地,在上述第一条件的基础上可以增加额外的约束条件,第一条件还包括以下至少一项:
第三小区在辅助设备转发的相同波束下的测量结果大于或等于第四阈值;
所述第三小区在所述辅助设备转发的相同波束下的测量结果,与所述第三小区在第二条件下的测量结果之间的差值大于第五阈值;
第三小区在第二条件下的测量结果大于或等于第六阈值;
第三小区的下行帧边界,与所述第一服务小区的下行帧边界的到达时间差,小于或等于第七阈值;
其中,第二条件包括:辅助设备不工作或辅助设备转发的波束不指向终端。
具体地,第三小区在辅助设备转发的相同波束下的测量结果大于或等于第四阈值,可以表示为:Mn>Thresh1,Thresh1表示第一服务小区配置的第四阈值;
第三小区在辅助设备转发的相同波束下的测量结果,与第三小区在第二条件下的测量结果之间的差值大于第五阈值,可以表示为:Mn-Mn0>Thresh2,Mn0为辅助设备不工作或者辅助设备转发的波束不指向终端时第三小区的测量结果,Thresh2表示第一服务小区配置的第五阈值;
第三小区在第二条件下的测量结果大于或等于第六阈值,可以表示为:Mn0>Thresh3,Thresh3为第一服务小区配置的第六阈值。
进一步可选地,终端确定当前的第一服务小区与第三小区的下行帧边界的到达时间差异(即确定不同小区下行帧边界的同步情况),当下行帧边界的到达时间差小于第七阈值Thresh4时,允许终端与第三小区建立连接。进一步,终端接收第三小区的SSB以及进行随机接入流程,实现终端连接到第三小区,并实现上下行同步。
进一步地,终端接入上述至少一个第三小区之后,第三小区即成为 第一小区。
对于根据网络侧设备的调度信息判断的方案,可选地,网络侧设备向终端发送调度信令,调度终端与第一小区进行随机接入,调度信令中配置随机接入的Msg1的RO资源和CF RA的preamble的参数,以及第一小区的用于通信的上下行部分带宽(Band Width Part,BWP)。
上述实施方式中,由于终端接入多个小区,因此其他小区的信号也为终端提供服务,不会成为干扰信号,降低了小区间干扰情况。
可选地,在一实施例中,该方法还包括:
网络侧设备向终端发送时间提前量TA,TA用于终端与第一服务小区和各个第一小区进行通信。
具体的,当前的第一服务小区的网络侧设备向终端发送TA,当终端同时接入当前的第一服务小区和其他的第二服务小区时,终端只接收当前的第一服务小区的TA,同时作用于当前的第一服务小区和其他的第二服务小区,即该TA也适用于其他的第二服务小区。
在一实施例中,终端在移动过程中可能会离开辅助设备的覆盖范围,若终端离开辅助设备的覆盖范围,终端切换到与网络侧设备直接通信的状态,即该方法还包括:
网络侧设备接收终端发送的指示信息,用于指示与网络侧设备直接通信;
可选地,网络侧设备向各个第一小区的网络侧设备发送通知消息,通知消息用于指示与终端断开连接。
具体地,终端按照当前的第一服务小区配置的测量波束,获取测量波束的测量结果,测量波束包括网络侧设备直接发送波束和网络侧设备发送并经辅助设备转发的波束。如果在辅助设备覆盖范围内终端发生过主从服务小区的切换,那么当前的第一服务小区需要为终端重新配置测量波束。
当网络侧设备直接发送波束的测量结果优于辅助设备转发波束的测 量结果时,终端切换到与网络侧设备直接通信的状态。同时,终端不再保持其他服务小区的连接,当前的第一服务小区对应的网络侧设备通知其他服务小区断开与终端的通信连接。
上述实施方式中,终端在移动过程中离开辅助设备的覆盖范围后,终端切换到与网络侧设备直接通信的状态,而无需再经过辅助设备转发,提高了通信效率。
在一实施例中,如图6所示,本实施例提供的小区切换方法,包括:
步骤201、终端获取终端的第一服务小区和至少一个第一小区的测量结果;
其中,第一小区为第一服务小区的邻小区,或终端的第二服务小区;第一服务小区和至少一个第一小区为共享使用辅助设备的小区。
该步骤的具体实现原理可以参见步骤101处的描述,此次不再赘述。
步骤202、终端基于第一服务小区和至少一个第一小区的测量结果进行小区切换。
具体地,终端可以直接根据测量结果确定是否进行小区切换,若终端确定进行小区切换,则终端可以向网络侧设备发送切换请求;
或者,终端可以将测量结果发送给网络侧设备,由网络侧设备确定是否进行小区切换,若网络侧设备确定进行小区切换,则网络侧设备向终端发送切换指示。
