Description

一种信息配置方法及网络设备、终端、存储介质
相关申请的交叉引用
本申请基于申请号为202211114727.3、申请日为2022年09月14日的中国专利申请提出,并要求该中国专利申请的优先权,该中国专利申请的全部内容在此引入本申请作为参考。
技术领域

背景技术
在网络节能场景中,当小区内终端的数量较少或者小区内物理资源块(Physical Resource Block,PRB)利用率比较低的时候,基站可以通过关闭一部分天线或者通道,进行基站节能。
当基站关闭部分天线或者通道时,原先的同步信号块(Sync Signal Block,SSB)/信道状态信息参考信号(Channel State Information Reference Signal,CSI-RS)的波束方向和波束大小都发生了改变,导致目前使用的波束并非终端的最优波束,需要进行传输配置指示(transmission configuration indicator,TCI)状态更新。
目前的TCI状态更新方式需要发送下行链路控制信息(Downlink Control Information,DCI)、媒体访问控制(Media Access Control,MAC)控制元素(Control Element,CE)、无线资源控制协议(Radio Resource Control,RRC)重配等消息,会导致TCI状态更新的信令开销大,且基站开关天线/通道会影响小区内的多个终端,使得小区级别信令开销增大,进而导致小区内物理下行控制信道(Physical Downlink Control Channel,PDCCH)拥塞的问题。

具体实施方式
为了能够更加详尽地了解本申请实施例的特点与技术内容,下面结合附图对本申请实施例的实现进行详细阐述,所附附图仅供参考说明之用,并非用来限定本申请实施例。
除非另有定义,本文所使用的所有的技术和科学术语与属于本申请的技术领域的技术人员通常理解的含义相同。本文中所使用的术语只是为了描述本申请实施例的目的,不是旨在限制本申请。
在以下的描述中,涉及到“一些实施例”,其描述了所有可能实施例的子集,但是可以理解,“一些实施例”可以是所有可能实施例的相同子集或不同子集,并且可以在不冲突的情况下相互结合。还需要指出,本申请实施例所涉及的术语“第一/第二/第三”仅是用于区别类似的对象,不代表针对对象的特定排序,可以理解地,“第一/第二/第三”在允许的情况下可以互换特定的顺序或先后次序,以使这里描述的本申请实施例能够以除了在这里图示或描述的以外的顺序实施。
目前,由于基站侧天线/通道的变化,原来的SSB/CSI-RS的波束方向发生了改变,导致该波束可能不再是终端的最优波束了,示例性的,如图1所示,基站天线/通道全部激活时,对应了CSI-RS1、CSI-RS2和CSI-RS3这三个波束,而当基站天线/通道关闭一半之后,对应了CSI-RS1和CSI-RS2这两个波束,且波束的宽度也变窄了。
针对PDCCH,PDSCH,CSI-RS的配置方式如下:
PDSCH:RRC配置最多128个TCI state,MAC CE激活最多8个,DCI中3bit指示1个。TCI state更新需要再发一次DCI。
PDCCH:RRC配置最多128个TCI state,MAC CE激活1个。TCI state更新需要再发一次MAC CE。
周期性CSI-RS:RRC配置。TCI state更新需要RRC重配。
半持续CSI-RS:MAC CE激活CSI-RS时一起配置。TCI state更新需要再发一次MAC CE。
非周期CSI-RS:RRC配置。TCI state更新需要RRC重配。
由于需要给PDCCH,PDSCH,CSI-RS更新TCI标识,基于上述配置方式可以看出传统更新TCI state的方式需要发送DCI,MAC CE,RRC重配等,导致信令开销非常大。而且基站开关天线/通道会影响小区内多个终端,导致小区级别信令开销增大,信令拥塞等问题。
为解决上述问题,本申请实施例提出一种信息配置方法,如图2所示,该方法可以包括:
S101、网络设备为终端配置第一参数和传输配置指示TCI状态的对应关系。
在一些实施例中,网络设备是一种为终端设备提供无线通信功能的设备,包括但不限于:长期演进(Long-Term Evolution,LTE)系统、新空口(New Radio,NR)系统或者授权辅助接入长期演进(Licensed-Assisted Access using Long-Term Evolution,LAA-LTE)系统中的演进型基站(evolutional Node B,可简称为eNB或e-NodeB)、宏基站、微基站(也可称为“小基站”)、微微基站、基站收发台(Base Transceiver Station,BTS)、基带单元(Base Band Unit,BBU)、接入站点(Access Point,AP)、传输站点(Transmission Point,TP)或新一代基站(new generation Node B,gNodeB)等。
在一实施例中,第一参数指示基站的天线工作状态或基站的通道工作状态。具体的可以根据实际情况进行选择,本申请实施例不做具体的限定。
在一实施例中,网络设备通过RRC或MAC CE为终端配置第一参数和传输配置指示TCI状态的对应关系,具体的可以根据实际情况进行选择,本申请实施例不做具体的限定。
在一种实施例中,网络设备为终端配置第一参数的每一值对应的一个TCI状态列表;其中,每个TCI状态列表中处于同一位置的TCI状态标识之间存在映射关系。
在另一种实施例中,网络设备为终端配置第一参数的每一值对应的多个TCI状态列表。
在再一种实施例中,网络设备为终端配置一个第四TCI状态列表,其中,第四TCI状态列表中的一个TCI状态标识对应第一参数的一个值。
需要说明的是,网络设备为每个CSI-RS资源配置TCI状态标识时,配置一个第四TCI状态列表。
在本申请实施例中,当网络设备为终端指示或更新第一参数的参数值时,终端利用第一参数和TCI状态的对应关系更新TCI状态。
针对上述一种实施例,当网络设备为终端指示或更新第一参数的参数值时,终端根据指示或更新前的第一参数值对应的第一TCI状态列表和指 示或更新后的第二参数值对应的第二TCI状态列表中TCI状态标识的位置映射关系,从第二TCI状态列表中读取更新后的TCI状态标识。
示例性的,基站配置TCI状态列表1={TCI State ID-1,TCI State ID-2,TCI State ID-3,TCI State ID-4}关联基站天线/通道工作状态1,TCI状态列表2={TCI State ID-2,TCI State ID-2,TCI State ID-3,TCI State ID-3}关联基站天线/通道工作状态2。当基站天线/通道工作状态从1调整为2时,终端当前使用的TCI状态1更新为TCI状态列表2。
针对上述另一种实施例,当网络设备为终端指示或更新第一参数的参数值时,网络设备向终端指示第二参数值对应的第三TCI状态列表,所述第三TCI状态列表为第二参数值对应的多个TCI状态列表中的一个TCI状态列表;终端根据指示或更新前的第一参数值对应的第一TCI状态列表和第二参数值对应的第三TCI状态列表中TCI状态标识的位置映射关系,从第三TCI状态列表中读取更新后的TCI状态标识。
对上述再一种实施例,当网络设备为终端指示或更新第一参数的参数值时,终端根据第四TCI状态列表、指示或更新前的第一参数值和指示或更新后的第二参数值,确定更新后的TCI状态标识。
需要说明的是,当网络设备未为终端配置第一参数和TCI状态的对应关系时,网络设备可以定义默认行为,具体的默认行为可以包括如下的第一行为、第二行为和第三行为。
在一种实施例中,网络设备定义第一参数的参数值变化时的第一行为,用于在检测出满足第一条件的情况下,指示终端不更新TCI状态;第一条件包括:网络设备未配置第一参数和TCI状态的关联关系,和/或当前TCI状态关联的参考信号标识不变,或者终端的TCI状态标识不变。
示例性的,当基站工作状态调整后,若基站保证TCI状态所关联的参考信号不变或者终端的最优TCI状态标识不变,此时终端无需更新TCI状态。
在另一种实施例中,网络设备定义第一参数的参数值变化时的第二行为,用于在检测出满足第二条件的情况下,指示终端继续使用同步信号和广播信道块SSB作为TCI状态的参考信号;第二条件包括:网络设备未配置第一参数和TCI状态的关联关系,和/或当前TCI状态的参考信号配置为SSB。
示例性的,如果TCI状态配置的就是SSB,那么终端继续使用该SSB作为默认TCI状态的参考信号。
在再一种实施例中,网络设备定义第一参数的参数值变化时的第三行为,用于在检测出满足第三条件的情况下,指示终端的TCI状态为最近时隙内监听了搜索空间的控制资源集CORESET中控制资源集标识最小的CORESET对应的TCI状态;第三条件为:网络设备未配置第一参数和TCI状态的关联关系。
需要说明的是,在网络设备为终端指示或更新第一参数的参数值时,网络设备为终端配置时间间隔,用于指示更新后的TCI状态的生效时间。
示例性的,基站通过指示基站天线/通道工作状态变化的信令,来为终端指示或更新第一参数的参数值,基站在信令中配置一个时间间隔,终端从接收到该信令加时间间隔后生效更新后的TCI状态。
需要说明是,网络设备未为终端配置时间间隔,此时,终端在接收到网络设备为终端指示或更新第一参数的参数值时,生效更新后的TCI状态。
可以理解的是,网络设备预先为终端配置了第一参数和TCI状态的对应关系,在第一参数的参数值变化时,终端可根据对应关系自动更新TCI状态,为减少TCI状态更新的信令开销,解决小区内PDCCH拥塞的问题提供了可能。
基于上述实施例,本申请实施例提出一种信息配置方法,应用于终端,如图3所示,该方法包括:
S201、接收网络设备配置的第一参数和传输配置指示TCI状态的对应关系。
在一些实施例中,终端设备可以称之为用户设备(User Equipment,UE)。该终端设备可以为个人通信业务(Personal Communication Service,PCS)电话、无绳电话、会话发起协议(Session Initiation Protocol,SIP)话机、无线本地环路(Wireless Local Loop,WLL)站、个人数字助理(Personal Digital Assistant,PDA)等设备,该终端设备也可以为智能手机、平板电脑、掌上电脑、移动台(Mobile Station,MS)、移动终端(Mobile Terminal)等等,该终端设备可以经无线接入网(Radio Access Network,RAN)与一个或多个网络设备进行通信。例如,终端设备可以是移动电话(或称为“蜂窝”电话)或具有终端设备的计算机等,例如,终端设备还可以是便携式、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音和/或数据。终端设备还可以为有无线通信功能的手持设备、计算设备或连接到无线调制解调器的其它处理设备、车载设备、可穿戴设备,未来演进的网络中的终端设备等,本申请实施不作限定。
需要说明的是,终端接收到网络设备指示或更新的第一参数的参数值时,利用第一参数和TCI状态的对应关系,更新TCI状态。
在一种实施例中,终端接收网络设备配置的第一参数的每一值对应的一个TCI状态列表;其中,每个TCI状态列表中处于同一位置的TCI状态标识之间存在映射关系。在终端接收到网络设备指示或更新第一参数的参数值时,根据指示或更新前的第一参数值对应的第一TCI状态列表和指示或更新后的第二参数值对应的第二TCI状态列表中TCI状态标识的位置映射关系,从第二TCI状态列表中读取更新后的TCI状态标识。
在另一种实施例中,终端接收网络设备配置的第一参数的每一值对应的多个TCI状态列表。在终端接收到网络设备指示或更新第一参数的参数 值时,接收网络设备指示的第二参数值对应的第三TCI状态列表,第三TCI状态列表为第二参数值对应的多个TCI状态列表中的一个TCI状态列表;根据指示或更新前的第一参数值对应的第一TCI状态列表和第二参数值对应的第三TCI状态列表中TCI状态标识的位置映射关系,从第三TCI状态列表中读取更新后的TCI状态标识。
在再一种实施例中,终端接收网络设备配置的一个第四TCI状态列表,其中,第四TCI状态列表中的一个TCI状态标识对应第一参数的一个值。在终端接收到网络设备指示或更新第一参数的参数值时,根据第四TCI状态列表、指示或更新前的第一参数值和指示或更新后的第二参数值,确定更新后的TCI状态标识。
需要说明的是,对于M-TRP场景,基站有时需要关闭一个TRP,但是目前对于M-DCI调度的M-TRP传输,如果RRC配置了2个CORESET池索引,那就默认是M-TRP,那所有CORESET位置都需要做PDCCH盲检。2个TRP对应的TCI终端都要维护测量,也就是2个TRP都还要一直工作,发送这些参考信号。因此当基站想关闭1个TRP时,终端接收网络设备通知的基站的传输接收节点TRP工作状态从多传输接收节点M-TRP更新为单传输接收节点S-TRP,终端停止测量一个CORESET池索引对应的控制资源集和物理下行共享信道PDSCH配置的TCI标识中的参考信号,并停止盲检一个CORESET池索引对应的CORESET中的候选PDCCH。
需要说明的是,当网络设备未为终端配置第一参数和TCI状态的对应关系时,网络设备可以定义默认行为。具体的,
第一行为:在网络设备检测出满足第一条件的情况下,终端接收网络设备指示的终端不更新TCI状态;第一条件包括:网络设备未配置第一参数和TCI状态的关联关系,和/或当前TCI状态关联的参考信号标识不变,或者终端的TCI状态标识不变。
第二行为:在网络设备检测出满足第二条件的情况下,终端接收网络设备指示的终端继续使用同步信号和广播信道块SSB作为TCI状态的参考信号;第二条件包括:网络设备未配置第一参数和TCI状态的关联关系,和/或当前TCI状态的参考信号配置为SSB。
第三行为:在网络设备检测出满足第三条件的情况下,终端接收网络设备指示的终端的TCI状态为最近时隙内监听了搜索空间的控制资源集CORESET中控制资源集标识最小的CORESET对应的TCI状态;第三条件为:网络设备未配置第一参数和TCI状态的关联关系。
可以理解的是,网络设备预先为终端配置了第一参数和TCI状态的对应关系,在第一参数的参数值变化时,终端根据对应关系自动更新TCI状态,为减少TCI状态更新的信令开销,解决小区内PDCCH拥塞的问题提供了可能。
