请参考图1,其示出了本公开实施例提供的一种无线通信***的结构示意图。如图1所示,无线通信***是基于移动通信技术的通信***,该无线通信***可以包括:若干个用户设备110以及若干个基站120。
其中,用户设备110可以是指向用户提供语音和/或数据连通性的设备。用户设备110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,用户设备110可以是物联网用户设备,如传感器设备、移动电话和具有物联网用户设备的计算机,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、远程用户设备(remote terminal)、接入用户设备(access terminal)、用户装置(user terminal)、用户代理(user agent)、用户设备(user device)、或用户设备(user equipment)。或者,用户设备110也可以是无人飞行器的设备。或者,用户设备110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用户设备。或者,用户设备110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120可以是无线通信***中的网络侧设备。其中,该无线通信***可以是***移动通信技术(the 4th generation mobile communication,4G)***,又称长期演进(Long Term Evolution,LTE)***;或者,该无线通信***也可以是5G***,又称新空口***或5G NR***。或者,该无线通信***也可以是5G***的再下一代***。其中,5G***中的接入网可以称为NG-RAN(New Generation-Radio Access Network,新一代无线接入网)。
其中,基站120可以是4G***中采用的演进型基站(eNB)。或者,基站120也可以是5G***中采用集中分布式架构的基站(gNB)。当基站120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120的具体实现方式不加以限定。
基站120和用户设备110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***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,用户设备110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。
这里,上述用户设备可认为是下面实施例的终端设备。
在一些实施例中,上述无线通信***还可以包含网络管理设备130。
若干个基站120分别与网络管理设备130相连。其中,网络管理设备130可以是无线通信***中的核心网设备,比如,该网络管理设备130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130的实现形态,本公开实施例不做限定。
为了便于本领域内技术人员理解,本公开实施例列举了多个实施方式以对本公开实施例的技术方案进行清晰地说明。当然,本领域内技术人员可以理解,本公开实施例提供的多个实施例,可以被单独执行,也可以与本公开实施例中其他实施例的方法结合后一起被执行,还可以单独或结合后与其他相关技术中的一些方法一起被执行;本公开实施例并不对此作出限定。
为了更好地理解本公开任一个实施例所描述的技术方案,首先,对相关技术中的应用场景进行说明:
在新空口(NR,New Radio)***中,普通终端在频率范围FR1下的最大带宽可达100MHz,在频率范围FR2下的最大带宽最大为400MHz
在一些实施例中,频率范围FR1频分双工(FDD,Frequency Division Duplexing)频段的下行接收和上行发送的中心频点间隔必须满足表一中的条件。
表一:终端的发送与接收的频率间隔
Figure PCTCN2022073058-appb-000001
Figure PCTCN2022073058-appb-000002
在一个实施例中,请参见图2,频率范围FR1的普通终端的最大带宽可达100MHz,终端侧的信道带宽可以和***带宽一样大,因此,在FDD***中,下行DL BWP和上行UL BWP独立切换,并且仍然可以确保切换后的BWP的中心频率之间的间隔符合相关要求。
但是请参见图3,针对RedCap终端,最大带宽只能到20MHz。终端带宽减少,BWP带宽的切换会带来收发中心频点的切换,如果允许下行BWP在***带宽内任意切换的话,会导致终端侧的收发拼点的间隔不能满足收发间隔要求。当收发间隔不能满足要求时,此时会出现无法同时收发数据的问题。
如图4所示,本实施例中提供一种切换BWP的方法,其中,该方法包括:
步骤41、确定切换带宽部分BWP的切换方式;
其中,切换方式包括:第一切换方式,切换下行BWP或者上行BWP;第二切换方式,切换下行BWP和上行BWP。
在一个实施例中,所述确定切换带宽部分BWP的切换方式,包括:
根据预定条件,确定切换所述BWP的切换方式;
其中,预定条件包括:基于第一切换方式执行BWP切换的目标上行BWP的参考频点与激活的下行BWP的参考频点之间的间隔在阈值范围内;或者,基于第一切换方式执行BWP切换的目标下行BWP的参考频点与激活的上行BWP的参考频点之间的间隔在阈值范围内。
需要说明的是,阈值范围可以是预定的数值范围,示例性地,阈值范围可以是预定的大于预定值的数值范围,还可以是大于第一预定值且小于第二预定值的范围,在此不做限定。为了更好地理解阈值范围,以下通过两个示例进行说明:
例如,要求的上行BWP与下行BWP之间的间隔的最小值为a,则阈值范围可以是:X≥a。这里,间隔在阈值范围内,则间隔≥a.
例如,要求的上行BWP与下行BWP之间的间隔的最小值为a,则阈值范围可以是:a≤X≤b。这里,间隔在阈值范围内,则a≤间隔≤b。
这里,本公开任一实施例所述的切换BWP的方法可以被终端执行,但不限于被终端执行,也可以被基站或者核心网中的其他网络通信节点执行,在此不做限定。需要说明的是,本公开中的将终端作为执行主体的示意,并不对本公开的技术方案进行限定。
在一个实施例中,该方法由终端执行,示例性地,终端确定切换带宽部分BWP的切换方式;其中,所述切换方式包括:第一切换方式,切换下行BWP或者上行BWP;第二切换方式,切换下行BWP和上行BWP;终端向基站发送指示所述切换方式的信息。基站接收终端发送的指示所述切换方式的信息;基站基于所述切换方式的信息指示的所述切换方式执行BWP切换。

这里,本公开所涉及的终端可以是但不限于是手机、可穿戴设备、车载终端、路侧单元(RSU,Road Side Unit)、智能家居终端、工业用传感设备和/或医疗设备等。在一些实施例中,该终端可以是Redcap终端或者预定版本的新空口NR终端(例如,R17的NR终端)。
本公开中涉及的基站可以是终端接入网络的接入设备。这里,基站可以为各种类型的基站,例如,第三代移动通信(3G)网络的基站、***移动通信(4G)网络的基站、第五代移动通信(5G)网络的基站或其它演进型基站。
在一个实施例中,终端当前工作在激活的上行BWP和激活的下行BWP且需要进行上行BWP切换;如果基于第一切换方式执行BWP切换的目标上行BWP的参考频点与激活的下行BWP的参考频点之间的间隔在阈值范围内,确定BWP的切换方式为第一切换方式;基于第一切换方式执行BWP切换。示例性地,基于第一切换方式执行BWP切换可以是:只切换上行BWP,即将上行BWP切换至目标上行BWP,而下行BWP不进行切换。这里,只切换上行BWP也可以理解为:执行上行BWP的独立切换。
在一个实施例中,终端当前工作在激活的上行BWP和激活的下行BWP且需要进行上行BWP切换;如果基于第一切换方式执行BWP切换的目标上行BWP的参考频点与激活的下行BWP的参考频点之间的间隔未在阈值范围内,确定BWP的切换方式为第二方式;基于第二方式执行BWP切换。示例性地,基于第二方式执行BWP切换可以是:切换上行BWP和下行BWP,即将上行BWP切换至目标上行BWP,将下行BWP切换至目标下行BWP。这里,切换上行BWP和下行BWP可以理解为:执行上行BWP和下行BWP的同步切换。

在一个实施例中,配置的具有相同BWP标识ID的下行BWP和上行BWP满足预设的收发数据的间隔要求。这里,满足预设的收发数据的间隔要求可以是下行BWP的中心频点与上行BWP的中心频点之间的间隔为预定间隔。例如,该预定间隔为Fs。请参见图5,上行BWP中的BWP1的中心频点和下行BWP中的BWP1的中心频点之间的间隔为Fs;上行BWP中的BWP2的中心频点和下行BWP中的BWP2的中心频点之间的间隔为Fs;上行BWP中的BWP3的中心频点和下行BWP中的BWP3的中心频点之间的间隔为Fs;上行BWP中的BWP4的中心频点和下行BWP中的BWP4的中心频点之间的间隔为Fs。
