在一个实施例中,所述根据预定协议,确定所述字段长度,包括:
根据所述预定协议,确定指示startingRB和nrofRBs的联合编码结果的IE的所述字段长度为第五值。
根据本公开实施例的第二方面,提供一种接收配置信息的方法,其中,所述方法由终端执行;所述方法包括:

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。

其中,基站120可以是4G系统中采用的演进型基站(eNB)。或者,基站120也可以是5G系统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,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。

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可以是无线通信系统中的核心网设备,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:
在一个实施例中,在系统消息中广播附加的TRS和/或CSI-RS的配置信息以及其是否在广播的状态信息。TRS和/或CSI-RS的配置信息可以认为与可用状态信息是分别指示的,即网络可能配置了TRS和/或CSI-RS,但是,网络并没有进行实际传输,也就是说,并没有将配置信息给处于RRC空闲态的终端使用。在一个实施例中,该方法是由基站的实现决定的。在一个实施例中,TRS和/或CSI-RS的配置信息可以设置在系统信息块(SIB,System Information Block)中。
在一个实施例中,请参见表1,示出了TRS配置的比特位数量。
表1:
Figure PCTCN2022076116-appb-000001
在一个实施例中,如果每个TRS资源集(TRS resource set)为65bit或者95bit,则全部的bit数目为:65*64=4160bits或者95*64=6080bits。此时,已经远远超出SIB块可以承担的总数量(约2800bit),因此,就需要对SIB进行分段。
在一个实施例中,如果可以避免分段,则需要考虑如何减少信令开销。请参见表1,占据比较大的字段有startingRB,即起始RB,但是,由于TRS仅仅给处于RRC空闲态的终端使用,其带宽不会超过控制资源集coreset0的大小,即96个物理资源块(PRB,(physical resource block),因此,7bit就足够了。
如图2所示,本实施例中提供一种发送配置信息的方法,其中,该方法由基站执行,该方法包括:
步骤21、发送预定参考信号的配置信息;
其中,预定参考信号包括以下中的至少一个:跟踪参考信号TRS;信道状态信息参考信号CSI-RS;并且其中用于指示配置信息的信息单元IE的字段长度在预定范围内。
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、第四代移动通信(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。
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。
这里,IE用于指示配置信息。每个IE的字段可以对应一个信息域,IE的字段长度可以是信息域所 占用的比特位的长度。需要说明的是,字段长度可以根据信息域所占用的比特位数量确定,例如,字段对应的信息域所占用的比特位为6位,则字段长度可以是6。应理解,信息单元IE可以为一个或多个,相应地,字段可以是TRS配置和/或CSI-RS中的以下至少之一:startingRB、nrofRBs、periodicityAndOffset、TRS-ResourceSetId和scramblingID等,在此不做限定。
示例性地,发送预定参考信号的配置信息;其中,预定参考信号包括以下中的至少一个:跟踪参考信号TRS;信道状态信息参考信号CSI-RS;并且其中用于指示配置信息的起始资源块startingRB和/或资源块数量nrofRBs的IE的字段长度在预定范围内。
在一个实施例中,可以是通过系统消息发送预定参考信号的配置信息,其中,预定参考信号包括以下中的至少一个:跟踪参考信号TRS;信道状态信息参考信号CSI-RS;并且其中用于指示配置信息的信息单元IE的字段长度在预定范围内。需要说明的是,该配置信息可以是通过SIB承载。
在一个实施例中,可以根据信令开销的要求参数,确定预定范围。示例性地,响应于信令开销的要求参数大于参数阈值,确定所述预定范围大于阈值范围;或者,响应于信令开销的要求参数小于参数阈值,确定所述预定范围小于阈值范围。如此,预定范围可以适应于信令开销的要求参数。
在一个实施例中,可以根据网络配置信息,确定配置信息的IE的字段长度。
在一个实施例中,根据网络配置信息指示的字段长度,确定用于指示配置信息的IE的字段长度。例如,网络配置信息指示的字段长度为7个比特位,则可以确定用于指示配置信息的IE的字段长度为7个比特位。这里,网络配置信息指示的字段长度在预定范围内。也就是说,通过网络配置信息直接指示字段的长度。
在一个实施例中,根据网络配置信息指示的预定IE的字段长度,确定用于指示配置信息的IE的字段长度。也就是说,根据网络配置信息指示的特定IE的字段长度来确定指示配置信息的IE的字段长度。
