Description

信息传输方法、装置、通信设备和存储介质 技术领域
本申请涉及无线通信技术领域但不限于无线通信技术领域,尤其涉及信息传输方法、装置、通信设备和存储介质。
背景技术
在第四代(4G,4th Generation)蜂窝移动通信系统中,为了支持物联网业务,提出了机器型通信(MTC,Machine Type Communication)和窄带物联网(NB-IoT,Narrow Band Internet of Things)两大技术。这两大技术主要针对的是低速率,高时延等场景。比如抄表,环境监测等场景。NB-IoT目前最大只能支持几百k的速率,MTC目前最大只能支持几M的速率。但同时另外一方面,随着物联网业务的不断发展,比如视频监控,智能家居,可穿戴设备和工业传感监测等业务的普及。这些业务通常要求几十到100M的速率,同时对时延也有相对较高的要求,因此LTE中的MTC,NB-IoT技术很难满足要求。
在第五代(5G,5th Generation)蜂窝移动通信系统的新空口(New radio)中,一种新类型用户设备(UE,User Equipment)被用以来覆盖这种中端物联网设备的要求。该新类型的UE,被称为轻量化用户设备(Reduced capability UE)或者简称为轻量空口(NR-lite)。
对于轻量化UE的要求是:低造价,低复杂度;一定程度的覆盖增强;功率节省。由于目前5G新空口(NR,New Radio)是针对高速率低时延等高端终端设计的,因此,当前的设计无法满足轻量化UE的上述要求。因此,需要对目前的NR系统进行改造用以满足轻量化UE的要求。

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5G蜂窝移动通信的 终端等UE,以及基站等。
本公开实施例的应用场景为,目前,当进行随机接入的UE所使用的物理随机接入信道(PRACH,Physical Random Access Channel)资源有相同的时间和相同的频率,那么这些UE的随机接入响应就会在相同的物理下行共享信道(PDSCH,physical downlink shared channel)资源中,并且由相同的PDCCH信令调度,即由相同的随机接入响应(RAR,Random Access Response)PDCCH信令调度。NR中承载RAR调度的搜索空间叫做类型1PDCCH公共搜索空间(type-1PDCCH CSS),承载的PDCCH信令是由随机接入无线电网络临时标识符(RA-RNTI)进行加扰循环冗余校验(CRC,Cyclic Redundancy Check)的。
RAR PDCCH信令的搜索空间在所对应的CORESET中根据资源确定规则确定对应的CCE资源,资源确定规则可以用表达式(1)表示:
Figure PCTCN2020098273-appb-000001
其中,

表示迭代值,对于搜索空间来说
Figure PCTCN2020098273-appb-000003
N CCE,p表示在一个CORESET中所包含的CCE的总数,p表示第p个物理资源块集,L表示CCE聚合程度,i=0,…,L-1,
Figure PCTCN2020098273-appb-000004
表示CCE聚合程度L所对应的候选传输位置的个数,
Figure PCTCN2020098273-appb-000005
n CI表示载波指示字段的值,对于搜索空间来说n CI=0。
当UE发送完随机接入请求后的N个时间单元,用户就开始在类型(type)1PDCCH CSS中监测RAR PDCCH信令。整个监测会持续X个时间单元,如果在X个时间单元内用户没有监测到任何RAR PDCCH信令,则证明这次随机接入失败。这里的X个时间单元被称为随机接入响应窗口。
轻量化UE和NR非轻量化UE要共同去监听随机接入响应,包括:采 用相同的RAR PDCCH资源和RAR PDSCH资源。随机接入PDCCH信令在一个搜索空间中传输,但是在实际中,轻量化UE和NR非轻量化UE的能力不同,共用一套随机接入的传输和接收流程会限制灵活性。
本实施例提供一种信息传输方法可以应用于移动通信网络中的基站中,如图2所示,信息传输方法可以包括:
步骤201:根据UE类型,发送与所述UE的类型对应的PDCCH信令;其中,所述PDCCH信令携带有针对所述UE的随机接入响应控制信息;其中,不同的UE类型对应于不同的PDCCH信令传输,所述随机接入响应控制信息,用于指示与随机接入响应相关联的调度信息。
不同类型的UE可以是具有不同数据传输能力和/或不同信号接收能力的UE。这里,数据传输能力可以包括:传输速率、和/或传输时延、和/或缓存大小、和/或接收传输块的大小的能力等。UE的类型可以有两种或两种以上。
示例性的,第一类UE和第二类UE可以是多种UE类型中的两类。第一类UE可以是5G蜂窝移动通信系统中的轻量化UE(Reduced capability UE)。第二类UE可以是5G蜂窝移动通信系统中的非轻量化UE,如增强移动宽带(eMBB,Enhanced Mobile Broadband)终端等。与第二类UE相比,第一类UE可以具有较大的缓存、较低的传输数量、较高的传输时延以及在单词接收中接收的传输块较大。
随机接入响应的调度信息可以包括随机接入响应的PDSCH资源信息以及调制与编码策略信息等。随机接入响应的调度信息可以是采用PDCCH资源传输的下行控制信息(DCI,Downlink Control Information)。基站可以通过在PDCCH信令承载随机接入响应控制信息,并基于随机接入响应控制信息指示的传输资源,发送随机接入响应。UE接收并解析随机接入响应控制信息,并在随机接入响应控制信息指示的PDSCH资源以及调制与编码策 略接收随机接入响应。这里,PDCCH信令可以是RAR PDCCH信令。
第一类UE的随机接入响应控制信息和第二类UE的随机接入响应控制信息携带于相同的PDCCH信令中。第一类UE和第二类UE可以是具有不同数据传输能力和/或不同信号接收能力的UE,因此,同一PDCCH信令需要同时满足第一类UE和第二类UE的对于数据传输要求和/或信号质量要求等,使得PDCCH信令传输资源范围同时受第一类UE和第二类UE的限制,降低了PDCCH信令传输资源配置的灵活性。
这里,可以采用第一类PDCCH信令传输和第二类PDCCH信令传输分别携带针对第一类UE的随机接入响应控制信息和针对第二类UE的随机接入响应控制信息。第一类PDCCH信令传输不同于第二类PDCCH信令传输。这里,第一类PDCCH信令传输不同于第二类PDCCH信令传输可以指第一类PDCCH信令的类型不同于第二类PDCCH信令的类型,例如,利用不同类型的DCI来携带随机接入响应控制信息;也可以指对第一类PDCCH信令与第二类PDCCH信令是同一类型的信令,但采用不同的传输方式(例如,不同的传输资源、不同的传输参数和/或不同的传输规则等)进行传输。
例如,第一类PDCCH信令传输和第二类PDCCH信令传输可以是具有不同传输资源的PDCCH信令传输。例如,第一类PDCCH信令传输所属的搜索空间和第二类PDCCH信令传输的搜索空间可以不同,或者,第一类PDCCH信令传输的传输周期和第二类PDCCH信令传输的传输周期可以不同,或者,第一类PDCCH信令传输的传输带宽和第二类PDCCH信令传输的传输带宽可以不同。
不同类型PDCCH信令传输可以满足不同类型UE对于数据传输的要求和/或信号质量的要求。例如,针对第一类UE对信号质量要求较高的情况,可以采用具有干扰较小的频域资源的第一类PDCCH信令传输。
UE在接收PDCCH信令时,可以根据自身UE类型对应的接收参数, 接收与UE类型对应的PDCCH信令。接收参数可以是预先设置在UE内部的。接收参数可以是PDCCH信令的传输资源参数、和/或PDCCH解扰序列、和/或PDCCH信令所属随机接入搜索空间时频资源参数等。
示例性的,第一类UE可以根据第一类UE对应的接收参数,接收第一类PDCCH信令。
不同PDCCH信令传输承载的随机接入响应控制信息可以不同,不同随机接入响应控制信息可以指示不同的随机接入响应的调度信息,如此,不同类型UE可以在不同传输资源接收各自的随机接入响应,提高了随机接入响应的传输灵活性,降低了不同类型UE的随机接入响应之间的耦合性。
如此,采用与UE类型对应的PDCCH信令传输分别携带与UE类型对应的随机接入响应控制信息,一方面,采用与UE类型对应的PDCCH信令传输携带随机接入响应控制信息,满足不同UE类型的不同传输需求,提高通信效率。另一方面,不同类型PDCCH信令传输可以分别满足不同类型UE的随机接入响应控制信息的传输需求,降低了不同类型UE的随机接入响应控制信息之间的耦合性,提高了随机接入响应控制信息的传输灵活性。
在一个实施例中,所述不同的UE类型对应的所述PDCCH信令传输的搜索空间所属的控制资源集CORESET不同。
CORESET包括搜索空间中的PDCCH信令在频域上占据的频段,以及在时域上占用的OFDM符号数等资源。
基站可以采用不同的CORESET分别发送不同UE的类型对应的PDCCH信令。
UE可以基于自身UE类型对应的CORESET,接收PDCCH信令。
示例性的,可以为非轻量化UE配置使用CORESET#1,可以为轻量化UE用户配置使用CORESET#0。
如此,通过不同UE类型的随机接入响应控制信息可以承载在采用不同 CORESET承载的PDCCH信令上,实现采用不同PDCCH信令携带不同类型UE的随机接入响应控制信息。
在一个实施例中,所述不同的UE类型对应的所述PDCCH信令传输的搜索空间不同。
这里,不同UE的类型对应的PDCCH信令可以通过不同的搜索空间进行承载。
这里,接收参数可以是搜索空间的资源参数,不同类型的UE可以根据各自搜索空间的资源参数,分别在各自UE类型对应的搜索空间接收各自的PDCCH。
资源参数可以包括搜索空间的频域参数和/或时域参数,不同的频域参数可以指示不同的频域资源,不同的时域参数可以指示不同的时域资源。
可以根据不同的UE类型,配置与UE类型对应的搜索空间。例如,可以针对不同UE类型的传输能力,配置与传输能力对应的搜索空间。
如此,通过不同搜索空间分别承载不同UE类型对应的PDCCH信令,使PDCCH信令所属搜索空间匹配对应的UE类型,提高了携带随机接入响应控制信息的PDCCH信令选择灵活性,进而使得不同类型PDCCH信令传输可以分别满足不同类型UE的随机接入响应控制信息的传输需求,降低了不同类型UE的随机接入响应控制信息之间的耦合性,减少解耦时数据解码导致的错误率,从而提高UE接收PDCCH信令的成功率。
在一个实施例中,所述发送与所述UE的类型对应的PDCCH信令,包括:
在按照资源确定规则确定的候选CCE资源上发送所述PDCCH信令;
其中,所述不同的UE类型对应的所述资源确定规则不同。
这里,在不同类型UE的共享CORESET上采用不同规则参数确定的CCE资源不同。
CCE资源是承载PDCCH信令的共享搜索空间传输资源的基本组成单位。承载PDCCH信令的搜索空间传输可以具有1个或多个CCE资源。
承载PDCCH信令的CCE资源可以采用如表达式(1)所示的资源确定规则确定的。不同资源确定规则可以得到不同的CCE资源。
这里,可以在不同类型UE的共享CORESET上,为不同的UE类型设置不同的资源确定规则,从而得到不同的候选CCE资源。不同的候选CCE资源可以用于承载不同UE类型的PDCCH信令。
如此,通过针对不同UE类型设置不同的资源确定规则,使得不同UE类型的随机接入响应控制信息可以承载在采用不同CCE资源承载的PDCCH信令上,实现采用不同PDCCH信令传输携带不同类型UE的随机接入响应控制信息。
在一个实施例中,所述不同的UE类型对应的所述资源确定规则的规则参数不同;
其中,所述规则参数包括:偏移量参数和/或随机化参数。
针对不同UE类型,可以采用不同的偏移量参数和/或随机化参数。
这里,偏移量参数可以为0。基于不同偏移量参数,可以通过资源确定规则得到不同的CCE资源,从而实现PDCCH信令传输资源不同;
或者,还可以将资源确定规则的预定规则参数随机化,采用不同的随机化参数得到不同的CCE资源。
示例性的,在表达式(1)所示资源确定规则的基础上设置偏移量参数X,可以得到如表达式(2)所示的资源确定规则,表达式(1)所示资源确定规则和表达式(2)所示的资源确定规则得到侧CCE资源不同。

表示CCE聚合程度L所对应的候选传输位置的个数,
Figure PCTCN2020098273-appb-000010
n CI表示载波指示字段的值,对于搜索空间来说n CI=0。
针对第一类UE,X可以不等于0,针对第二类UE,X可以为0。如此,第二类UE可以采用相关技术中的CCE资源传输第二PDCCH信令。第一类UE可以采用不同于第二类UE的CCE资源传输第一PDCCH信令。
例如,针对非轻量化UE配置,X可以为0;针对轻量化UE配置,X可以不等于0。
偏移量参数可以是针对现有资源确定规则具体参数的偏移量。例如,偏移量参数可以是表达式一种
Figure PCTCN2020098273-appb-000011
的偏移量。
示例性的,针对非轻量化UE配置,
Figure PCTCN2020098273-appb-000012
的偏移量可以取0,针对轻量化UE配置,
Figure PCTCN2020098273-appb-000013
的偏移量可以取非0数。如此,可以实现为非轻量化UE和轻量化UE配置不同的CCE资源。
在一个实施例中,所述不同的UE类型对应的所述PDCCH信令的PDCCH资源的聚合等级不同;
和/或,
所述不同的UE类型对应的PDCCH信令的PDCCH资源的候选传输位置个数不同;
和/或,
所述不同的UE类型对应的PDCCH信令的候选重复传输位置不同。
聚合等级可以是组成一个PDCCH资源的CCE资源个数。聚合等级可以为1,2,4或8。聚合等级可以表征PDCCH资源中CCE资源个数,例如聚合等级为8的PDCCH资源中CCE资源个数为8。
不同聚合等级的PDCCH资源不同。因此,采用不同聚合等级的PDCCH资源分别传输不同UE的类型对应的PDCCH信令,如此,可以实现采用不同PDCCH信令携带不同类型UE的随机接入响应控制信息。
搜索空间中具有多个CCE资源,例如,搜索空间中具有88个。相同聚合等级的PDCCH资源在搜索空间的位置可以有多个。即PDCCH资源的候选传输位置有多个。这里,可以采用不同候选传输位置的PDCCH资源分别传输第一PDCCH信令和第二PDCCH信令。如此,可以实现采用不同PDCCH信令携带不同类型UE的随机接入响应控制信息。
示例性的,如图3所示,在搜索空间中具有n个CCE资源,以n=88为例,聚合等级为8的PDCCH资源在搜索空间中可以有两个候选位置:候选位置1和候选位置2,可以采用候选位置1的PDCCH资源传输第一PDCCH信令,采用候选位置2的PDCCH资源传输第二PDCCH信令。
在PDCCH信令重传过程中,不同UE类型的PDCCH信令采用的候选重复传输位置可以不同。如此,针对PDCCH信令重传,可以实现采用不同PDCCH信令携带不同类型UE的随机接入响应控制信息。
在一个实施例中,所述发送与所述UE的类型对应的PDCCH信令,包括:
在所述UE的类型对应的随机接入响应窗内,发送所述PDCCH信令;
其中,所述不同的UE类型对应的所述随机接入响应窗不同。
当用户发送完随机接入前导码后的N个时间单元,UE就开始在type 1PDCCH CSS中监听PDCCH信令。监听PDCCH信令的的时间段称随机接入响应窗。随机接入响应窗可以持续M个时间单元,如果在M个时间单元内用户没有监测到任何PDCCH信令,则证明这次随机接入失败。
这里,针对不同类型UE的类型,基站可以在不同随机接入响应窗发送PDCCH信令。UE根据自身的类型,在不同的随机接入响应窗监听PDCCH 信令。
如此,通过针对不同UE类型设置不同的随机接入响应窗,使得不同UE类型的随机接入响应控制信息可以承载在采用随机接入响应窗的PDCCH信令上,实现采用不同PDCCH信令携带不同类型UE的随机接入响应控制信息。
在一个实施例中,所述不同的UE类型对应的所述随机接入响应窗与随机接入前导码的时间间隔不同;
和/或,
所述不同的UE类型对应的所述随机接入响应窗的持续时长不同。
当用户发送完随机接入前导码后的N个时间单元,UE就开始在type 1PDCCH CSS中监听PDCCH信令。监听PDCCH信令的的时间段称随机接入响应窗。随机接入响应窗可以持续M个时间单元,如果在M个时间单元内用户没有监测到任何PDCCH信令,则证明这次随机接入失败。
这里,针对不同类型UE的类型,N和/或M的值不同,以得到不同的随机接入响应窗。
在一个实施例中,所述不同的UE类型对应的所述PDCCH信令的加扰序列不同。
为区分不同UE类型对应的PDCCH信令,基站可以采用不同的加扰序列分别对不同UE类型对应的PDCCH信令进行加扰。
示例性的,采用第一类UE对应的加扰序列对第一类PDCCH信令传输进行加扰,采用第二类UE对应的加扰序列对第二类PDCCH信令传输进行加扰。
例如,可以采用第一类UE和第二类UE对应的UE标识分别对第一类PDCCH信令传输和第二类PDCCH信令传输进行加扰。这里,第一类UE的UE标识不同于第二类UE的UE标识。第一类UE的UE标识不同于第 二类UE的UE标识可以是标识比特数不同,和/或,编码方式不同。
接收参数可以是UE的解扰序列。同一类UE的加扰序列和解扰序列相同。UE接收到PDCCH信令后,可以采用自身对应的解扰序列对PDCCH信令进行解扰,如果解扰成功则确定该PDCCH信令是发送给自身的PDCCH信令。
如此,通过同一搜索空间承载不同类型的PDCCH信令,提高的搜索空间的承载能力,提高通信效率。
在一个实施例中,所述加扰序列为随机接入无线电网络临时标识符RA-RNTI,其中,不同类型所述UE的RA-RNTI不同。
这里,可以为不同类型的UE分配不同的RA-RNTI,基站采用与UE类型对应的RA-RNTI对PDCCH信令加扰。
UE侧接收到PDCCH信令后,可以采用与自身类型对应的RA-RNTI进行解扰。
示例性的,针对非轻量化UE可以采用相关技术的RA-RNTI。针对轻量化UE,可以由通信协议新规定一个不同的RA-RNTI,或者可以由基站配置一个不同的RA-RNTI。
示例性的,可以由通信协议规定不同类型UE的RA-RNTI的计算方式。针对第一类UE的RA-RNTI,可以采用相关技术中如表达式(3)所示的计算方式进行计算。
RA-RNTI=1+t_id+10*f_id          (3)
其中,t_id表示发送随机接入前导码的起始位置的子帧标识(ID)号(范围是0-9),f_id表示四元素组中的f_RA值(范围是0-5)。
针对第二类UE,在表达式(3)的基础上调整计算参数,计算得到第二类UE的RA-RNTI,使得第一类UE的RA-RNTI和第二类UE的RA-RNTI不同。例如,可以在表达式(3)的基础上调整常数1,得到表达式(4), 通过表达式(4)所示的计算方式计算第二类UE的RA-TNTI。
RA-RNTI=2+t_id+10*f_id         (4)
在一个实施例中,所述随机接入响应控制信息调度的所述不同的UE类型对应PDSCH资源不同;其中,所述PDSCH资源,用于传输所述随机接入响应。
PDCCH信令中的随机接入响应控制信息可以用于调度随机接入响应的PDSCH资源,这里,针对不同UE的类型,可以调度不同的PDSCH资源传输随机接入响应。
如此,采用与UE的随机接入响应通过与UE类型对应的PDSCH资源传输,一方面,采用与UE类型对应的PDSCH资源传输随机接入响应,满足不同UE类型的不同传输需求,提高通信效率。另一方面,降低了不同类型UE的随机接入响应之间的耦合性,提高了随机接入响应的传输灵活性。
在一个实施例中,所述方法还包括:
响应于第一类UE的初始宽带部分BWP的带宽等于CORESET#0的带宽,采用第二类UE的PDCCH信令传输承载所述第一类UE的随机接入响应控制信息。
基站可以配置承载不同UE的随机接入响应控制信息的PDCCH信令。例如,基站可以配置采用第二类PDCCH信令传输承载。
在搜索空间配置中,如果不同类型UE的BWP相同,则不同类型UE可以监测同一个搜索空间,即不同类型UE的PDCCH信令传输相同。
示例性的,非轻量化UE和轻量化UE是否使用不同的PDCCH信令传输可以由基站进行配置或者根据其他条件进行决定。例如,如果轻量化UE的初始BWP的带宽等于CORESET#0的带宽,则配置轻量化UE使用非轻量化UE相同的PDCCH信令传输携带随机接入响应控制信息。
如此,基站可以灵活配置UE使用的PDCCH。
在一个实施例中,所述方法还包括:发送配置信令,所述配置信令,用于指示第一类UE的所述随机接入响应控制信息由第一类UE的PDCCH信令承载或由第二类UE的PDCCH信令承载。
基站可以为不同类型UE配置承载随机接入响应控制信息的PDCCH信令。例如,基站可以为第一类UE配置采用第二类UE的第二类PDCCH信令传输承载随机接入响应控制信息。
如此,基站可以灵活配置UE使用的PDCCH。
在一个实施例中,如图4所示,所述方法还包括:
步骤202:接收所述UE发送的随机接入前导码;
步骤203:根据所述随机接入前导码携带的类型指示信息,确定所述UE的类型。
UE通过2步骤随机接入法或4步骤随机接入法进入基站时,首先会向基站发送随机接入前导码。UE可以将指示自身类型的类型指示信息携带在随机接入前导码中。
基站接收到随机接入前导码后,根据类型指示信息确定UE的类型,进而发送与该类型对应的PDCCH信令。
本实施例提供一种信息传输方法可以应用于移动通信网络中的UE中,如图5所示,信息传输方法可以包括:
步骤501:采用与所述UE的类型对应的接收参数,接收PDCCH信令;其中,所述PDCCH信令携带有所述UE随机接入响应控制信息;其中,不同的UE类型对应于不同的PDCCH信令传输,随机接入响应控制信息,用于指示与随机接入响应相关联的调度信息。
不同类型的UE可以是具有不同数据传输能力和/或不同信号接收能力的UE。这里,数据传输能力可以包括:传输速率、和/或传输时延、和/或缓存大小、和/或接收传输块的大小的能力等。UE的类型可以有两种或两种 以上。
示例性的,第一类UE和第二类UE可以是多种UE类型中的两类。第一类UE可以是5G蜂窝移动通信系统中的轻量化UE(Reduced capability UE)。第二类UE可以是5G蜂窝移动通信系统中的非轻量化UE,如增强移动宽带(eMBB,Enhanced Mobile Broadband)终端等。与第二类UE相比,第一类UE可以具有较大的缓存、较低的传输数量、较高的传输时延以及在单词接收中接收的传输块较大。
随机接入响应的调度信息可以包括随机接入响应的PDSCH资源信息以及调制与编码策略信息等。随机接入响应的调度信息可以是采用PDCCH资源传输的下行控制信息(DCI,Downlink Control Information)。基站可以通过在PDCCH信令承载随机接入响应控制信息,并基于随机接入响应控制信息指示的传输资源,发送随机接入响应。UE接收并解析随机接入响应控制信息,并在随机接入响应控制信息指示的PDSCH资源以及调制与编码策略接收随机接入响应。这里,PDCCH信令可以是RAR PDCCH信令。
第一类UE的随机接入响应控制信息和第二类UE的随机接入响应控制信息携带于相同的PDCCH信令中。第一类UE和第二类UE可以是具有不同数据传输能力和/或不同信号接收能力的UE,因此,同一PDCCH信令需要同时满足第一类UE和第二类UE的对于数据传输要求和/或信号质量要求等,使得PDCCH信令传输资源范围同时受第一类UE和第二类UE的限制,降低了PDCCH信令传输资源配置的灵活性。
这里,可以采用第一类PDCCH信令传输和第二类PDCCH信令传输分别携带针对第一类UE的随机接入响应控制信息和针对第二类UE的随机接入响应控制信息。第一类PDCCH信令传输不同于第二类PDCCH信令传输。这里,第一类PDCCH信令传输不同于第二类PDCCH信令传输可以指第一类PDCCH信令的类型不同于第二类PDCCH信令的类型,例如,利用不同 类型的DCI来携带随机接入响应控制信息;也可以指对第一类PDCCH信令与第二类PDCCH信令是同一类型的信令,但采用不同的传输方式(例如,不同的传输资源、不同的传输参数和/或不同的传输规则等)进行传输。
例如,第一类PDCCH信令传输和第二类PDCCH信令传输可以是具有不同传输资源的PDCCH信令传输。例如,第一类PDCCH信令传输所属的搜索空间和第二类PDCCH信令传输的搜索空间可以不同,或者,第一类PDCCH信令传输的传输周期和第二类PDCCH信令传输的传输周期可以不同,或者,第一类PDCCH信令传输的传输带宽和第二类PDCCH信令传输的传输带宽可以不同。
不同类型PDCCH信令传输可以满足不同类型UE对于数据传输的要求和/或信号质量的要求。例如,针对第一类UE对信号质量要求较高的情况,可以采用具有干扰较小的频域资源的第一类PDCCH信令传输。
UE在接收PDCCH信令时,可以根据自身UE类型对应的接收参数,接收与UE类型对应的PDCCH信令。接收参数可以是预先设置在UE内部的。接收参数可以是PDCCH信令的传输资源参数、和/或PDCCH解扰序列、和/或PDCCH信令所属随机接入搜索空间时频资源参数等。
示例性的,第一类UE可以根据第一类UE对应的接收参数,接收第一类PDCCH信令。
不同PDCCH信令传输承载的随机接入响应控制信息可以不同,不同随机接入响应控制信息可以指示不同的随机接入响应的调度信息,如此,不同类型UE可以在不同传输资源接收各自的随机接入响应,提高了随机接入响应的传输灵活性,降低了不同类型UE的随机接入响应之间的耦合性。
如此,采用与UE类型对应的PDCCH信令传输分别携带与UE类型对应的随机接入响应控制信息,一方面,采用与UE类型对应的PDCCH信令传输携带随机接入响应控制信息,满足不同UE类型的不同传输需求,提高 通信效率。另一方面,不同类型PDCCH信令传输可以分别满足不同类型UE的随机接入响应控制信息的传输需求,降低了不同类型UE的随机接入响应控制信息之间的耦合性,提高了随机接入响应控制信息的传输灵活性。
在一个实施例中,所述接收参数包括:控制资源集CORESET参数;
所述采用与所述UE的类型对应的接收参数,接收PDCCH信令,包括:
在所述UE的类型对应的所述PDCCH信令传输的搜索空间所属的控制资源集CORESET上接收所述PDCCH信令,其中,所述不同的UE类型对应的所述PDCCH信令传输的搜索空间所属的控制资源集CORESET不同。
CORESET包括搜索空间中的PDCCH信令在频域上占据的频段,以及在时域上占用的OFDM符号数等资源。
基站可以采用不同的CORESET分别发送不同UE的类型对应的PDCCH信令。
UE可以基于自身UE类型对应的CORESET,接收PDCCH信令。
示例性的,可以为非轻量化UE配置使用CORESET#1,可以为轻量化UE用户配置使用CORESET#0。
如此,通过不同UE类型的随机接入响应控制信息可以承载在采用不同CORESET承载的PDCCH信令上,实现采用不同PDCCH信令携带不同类型UE的随机接入响应控制信息。
在一个实施例中,所述接收参数,包括:资源参数;
所述采用与所述UE的类型对应的接收参数,接收PDCCH信令,包括:
采用与所述UE的类型对应的所述资源参数,在所述UE的类型对应的所述PDCCH信令传输的搜索空间接收所述PDCCH信令,其中,所述不同的UE类型对应的所述PDCCH信令传输的搜索空间不同。
这里,不同UE的类型对应的PDCCH信令可以通过不同的搜索空间进行承载。
这里,接收参数可以是搜索空间的资源参数,不同类型的UE可以根据各自搜索空间的资源参数,分别在各自UE类型对应的搜索空间接收各自的PDCCH。
资源参数可以包括搜索空间的频域参数和/或时域参数,不同的频域参数可以指示不同的频域资源,不同的时域参数可以指示不同的时域资源。
可以根据不同的UE类型,配置与UE类型对应的搜索空间。例如,可以针对不同UE类型的传输能力,配置与传输能力对应的搜索空间。
如此,通过不同搜索空间分别承载不同UE类型对应的PDCCH信令,使PDCCH信令所属搜索空间匹配对应的UE类型,提高了携带随机接入响应控制信息的PDCCH信令选择灵活性,进而使得不同类型PDCCH信令传输可以分别满足不同类型UE的随机接入响应控制信息的传输需求,降低了不同类型UE的随机接入响应控制信息之间的耦合性,减少解耦时数据解码导致的错误率,从而提高UE接收PDCCH信令的成功率。
在一个实施例中,所述资源参数,包括:资源确定规则的规则参数;
所述采用与所述UE的类型对应的接收参数,接收PDCCH信令,包括:
在按照所述UE的类型对应的所述PDCCH信令的资源确定规则确定的候选CCE资源上接收所述PDCCH信令;
其中,所述不同的UE类型对应的所述资源确定规则不同。
这里,在不同类型UE的共享CORESET上采用不同规则参数确定的CCE资源不同。
CCE资源是承载PDCCH信令的共享搜索空间传输资源的基本组成单位。承载PDCCH信令的搜索空间传输可以具有1个或多个CCE资源。
承载PDCCH信令的CCE资源可以采用如表达式(1)所示的资源确定规则确定的。不同资源确定规则可以得到不同的CCE资源。
这里,可以在不同类型UE的共享CORESET上,为不同的UE类型设 置不同的资源确定规则,从而得到不同的候选CCE资源。不同的候选CCE资源可以用于承载不同UE类型的PDCCH信令。
如此,通过针对不同UE类型设置不同的资源确定规则,使得不同UE类型的随机接入响应控制信息可以承载在采用不同CCE资源承载的PDCCH信令上,实现采用不同PDCCH信令传输携带不同类型UE的随机接入响应控制信息。
在一个实施例中,所述不同的UE类型对应的所述资源确定规则的规则参数不同;
其中,所述规则参数包括:偏移量参数和/或随机化参数。
针对不同UE类型,可以采用不同的偏移量参数和/或随机化参数。
这里,偏移量参数可以为0。基于不同偏移量参数,可以通过资源确定规则得到不同的CCE资源,从而实现PDCCH信令传输资源不同;
或者,还可以将资源确定规则的预定规则参数随机化,采用不同的随机化参数得到不同的CCE资源。
示例性的,在表达式(1)所示资源确定规则的基础上设置偏移量参数X,可以得到如表达式(2)所示的资源确定规则,表达式(1)所示资源确定规则和表达式(2)所示的资源确定规则得到侧CCE资源不同。其中,
Figure PCTCN2020098273-appb-000014
表示迭代值,对于搜索空间来说
Figure PCTCN2020098273-appb-000015
N CCE,p表示在一个CORESET中所包含的CCE的总数,p表示第p个物理资源块集,L表示CCE聚合程度,i=0,…,L-1,
Figure PCTCN2020098273-appb-000016
表示CCE聚合程度L所对应的候选传输位置的个数,
Figure PCTCN2020098273-appb-000017
n CI表示载波指示字段的值,对于搜索空间来说n CI=0。
针对第一类UE,X可以不等于0,针对第二类UE,X可以为0。如此,第二类UE可以采用相关技术中的CCE资源传输第二PDCCH信令。第一 类UE可以采用不同于第二类UE的CCE资源传输第一PDCCH信令。
例如,针对非轻量化UE配置,X可以为0;针对轻量化UE配置,X可以不等于0。
偏移量参数可以是针对现有资源确定规则具体参数的偏移量。例如,偏移量参数可以是表达式一种
Figure PCTCN2020098273-appb-000018
的偏移量。
示例性的,针对非轻量化UE配置,
Figure PCTCN2020098273-appb-000019
的偏移量可以取0,针对轻量化UE配置,
Figure PCTCN2020098273-appb-000020
的偏移量可以取非0数。如此,可以实现为非轻量化UE和轻量化UE配置不同的CCE资源。
在一个实施例中,所述资源参数包括以下之一:
所述PDCCH信令的PDCCH资源的聚合等级;
和/或,
所述PDCCH信令的PDCCH资源的候选传输位置个数;
和/或,
所述PDCCH信令的候选重复传输位置。
聚合等级可以是组成一个PDCCH资源的CCE资源个数。聚合等级可以为1,2,4或8。聚合等级可以表征PDCCH资源中CCE资源个数,例如聚合等级为8的PDCCH资源中CCE资源个数为8。
不同聚合等级的PDCCH资源不同。因此,采用不同聚合等级的PDCCH资源分别传输不同UE的类型对应的PDCCH信令,如此,可以实现采用不同PDCCH信令传输携带不同类型UE的随机接入响应控制信息。
搜索空间中具有多个CCE资源,例如,搜索空间中具有88个。相同聚合等级的PDCCH资源在搜索空间的位置可以有多个。即PDCCH资源的候选传输位置有多个。这里,可以采用不同候选传输位置的PDCCH资源分别传输第一PDCCH信令和第二PDCCH信令。如此,可以实现采用不同PDCCH信令传输携带不同类型UE的随机接入响应控制信息。
示例性的,如图3所示,在搜索空间中具有n个CCE资源,以n=88为例,聚合等级为8的PDCCH资源在搜索空间中可以有两个候选位置:候选位置1和候选位置2,可以采用候选位置1的PDCCH资源传输第一PDCCH信令,采用候选位置2的PDCCH资源传输第二PDCCH信令。
在PDCCH信令重传过程中,不同UE类型的PDCCH信令采用的候选重复传输位置可以不同。如此,针对PDCCH信令重传,可以实现采用不同PDCCH信令传输携带不同类型UE的随机接入响应控制信息。
在一个实施例中,所述接收参数,包括:随机接入响应窗参数;
所述采用与所述UE的类型对应的接收参数,接收PDCCH信令,包括:
在所述UE的类型对应的所述随机接入响应窗内,接收所述PDCCH信令;
其中,所述不同的UE类型对应的所述随机接入响应窗不同。
当用户发送完随机接入前导码后的N个时间单元,UE就开始在type 1PDCCH CSS中监听PDCCH信令。监听PDCCH信令的的时间段称随机接入响应窗。随机接入响应窗可以持续M个时间单元,如果在M个时间单元内用户没有监测到任何PDCCH信令,则证明这次随机接入失败。
这里,针对不同类型UE的类型,基站可以在不同随机接入响应窗发送PDCCH信令。UE根据自身的类型,在不同的随机接入响应窗监听PDCCH信令。
如此,通过针对不同UE类型设置不同的随机接入响应窗,使得不同UE类型的随机接入响应控制信息可以承载在采用随机接入响应窗的PDCCH信令上,实现采用不同PDCCH信令传输携带不同类型UE的随机接入响应控制信息。
在一个实施例中,所述不同的UE类型对应的所述随机接入响应窗与随机接入前导码的时间间隔不同;
和/或,
所述不同的UE类型对应的所述随机接入响应窗的持续时长不同。
当用户发送完随机接入前导码后的N个时间单元,UE就开始在type 1PDCCH CSS中监听PDCCH信令。监听PDCCH信令的的时间段称随机接入响应窗。随机接入响应窗可以持续M个时间单元,如果在M个时间单元内用户没有监测到任何PDCCH信令,则证明这次随机接入失败。
这里,针对不同类型UE的类型,N和/或M的值不同,以得到不同的随机接入响应窗。
在一个实施例中,所述采用与所述UE的类型对应的接收参数,接收PDCCH信令,包括:
采用与所述UE的类型对应的解扰序列,解扰所述PDCCH信令;
其中,所述不同的UE类型对应的所述PDCCH信令的加扰序列不同。
为区分不同UE类型对应的PDCCH信令,基站可以采用不同的加扰序列分别对不同UE类型对应的PDCCH信令进行加扰。
示例性的,采用第一类UE对应的加扰序列对第一类PDCCH信令传输进行加扰,采用第二类UE对应的加扰序列对第二类PDCCH信令传输进行加扰。
例如,可以采用第一类UE和第二类UE对应的UE标识分别对第一类PDCCH信令传输和第二类PDCCH信令传输进行加扰。这里,第一类UE的UE标识不同于第二类UE的UE标识。第一类UE的UE标识不同于第二类UE的UE标识可以是标识比特数不同,和/或,编码方式不同。
接收参数可以是UE的解扰序列。同一类UE的加扰序列和解扰序列相同。UE接收到PDCCH信令后,可以采用自身对应的解扰序列对PDCCH信令进行解扰,如果解扰成功则确定该PDCCH信令是发送给自身的PDCCH信令。
如此,通过同一搜索空间承载不同类型的PDCCH信令,提高的搜索空间的承载能力,提高通信效率。
在一个实施例中,所述加扰序列为随机接入无线电网络临时标识符RA-RNTI,其中,不同类型所述UE的RA-RNTI不同。
这里,可以为不同类型的UE分配不同的RA-RNTI,基站采用与UE类型对应的RA-RNTI对PDCCH信令加扰。
UE侧接收到PDCCH信令后,可以采用与自身类型对应的RA-RNTI进行解扰。
示例性的,针对非轻量化UE可以采用相关技术的RA-RNTI。针对轻量化UE,可以由通信协议新规定一个不同的RA-RNTI,或者可以由基站配置一个不同的RA-RNTI。
示例性的,可以由通信协议规定不同类型UE的RA-RNTI的计算方式。针对第一类UE的RA-RNTI,可以采用相关技术中如表达式(3)所示的计算方式进行计算。其中,t_id表示发送随机接入前导码的起始位置的子帧标识(ID)号(范围是0-9),f_id表示四元素组中的f_RA值(范围是0-5)。
针对第二类UE,在表达式(3)的基础上调整计算参数,计算得到第二类UE的RA-RNTI,使得第一类UE的RA-RNTI和第二类UE的RA-RNTI不同。例如,可以在表达式(3)的基础上调整常数1,得到表达式(4),通过表达式(4)所示的计算方式计算第二类UE的RA-TNTI。
RA-RNTI=2+t_id+10*f_id           (4)
在一个实施例中,所述方法还包括:
采用所述随机接入响应控制信息调度的的PDSCH资源,接收所述随机接入响应;
其中,所述不同的UE类型对应的所述PDSCH资源不同。
PDCCH信令中的随机接入响应控制信息可以用于调度随机接入响应 的PDSCH资源,这里,针对不同UE的类型,可以调度不同的PDSCH资源传输随机接入响应。
如此,采用与UE的随机接入响应通过与UE类型对应的PDSCH资源传输,一方面,采用与UE类型对应的PDSCH资源传输随机接入响应,满足不同UE类型的不同传输需求,提高通信效率。另一方面,降低了不同类型UE的随机接入响应之间的耦合性,提高了随机接入响应的传输灵活性。
在一个实施例中,所述方法还包括:
响应于所述UE为第一类UE,接收基站响应于所述第一类UE的初始宽带部分BWP的带宽等于CORESET#0的带宽发送的,采用第二类UE的PDCCH信令传输承载的所述第一类UE的资源指示信息。
基站可以配置承载不同UE的随机接入响应控制信息的PDCCH信令。例如,基站可以配置采用第二类PDCCH信令传输承载。
在搜索空间配置中,如果不同类型UE的BWP相同,则不同类型UE可以监测同一个搜索空间,即不同类型UE的PDCCH信令传输相同。
示例性的,非轻量化UE和轻量化UE是否使用不同的PDCCH信令传输可以由基站进行配置或者根据其他条件进行决定。例如,如果轻量化UE的初始BWP的带宽等于CORESET#0的带宽,则配置轻量化UE使用非轻量化UE相同的PDCCH信令传输携带随机接入响应控制信息。
如此,基站可以灵活配置UE使用的PDCCH。
在一个实施例中,所述方法还包括:
接收配置信令,采用所述配置信令指示的PDCCH信令接收所述随机接入响应控制信息。
基站可以为不同类型UE配置承载随机接入响应控制信息的PDCCH信令传输。例如,基站可以为第一类UE配置采用第二类UE的第二类PDCCH信令传输承载随机接入响应控制信息。
如此,基站可以灵活配置UE使用的PDCCH。
在一个实施例中,如图6所示,所述方法还包括:
步骤502:向基站发送随机接入前导码,其中,所述随机接入前导码携带有指示所述UE的类型的类型指示信息。
UE通过2步骤随机接入法或4步骤随机接入法进入基站时,首先会向基站发送随机接入前导码。UE可以将指示自身类型的类型指示信息携带在随机接入前导码中。
基站接收到随机接入前导码后,根据类型指示信息确定UE的类型,进而发送与该类型对应的PDCCH信令。
以下结合上述任意实施例提供一个具体示例:
方案的核心在于给非NR-liteUE与NR-liteUE使用独立的随机接入响应发送流程。
要点一:分别传输非NR-liteUE与NR-liteUE的RAR PDCCH。下面是实现分开传输的手段。
方法一:给NR-liteUE与非NR-liteUE配置不同的CORESET用来承载对应的type-1PDCCH CSS。
方法二:非NR-liteUE与NR-liteUE使用不同的预设规则,或者在预设规则中使用不同的参数得到对应搜索空间所对应的CCE资源。比如,非NR-liteUE仍然复用原有的规则,即表达式(1);对应NR-liteUE可以在原有基础上加上X的偏移,即表达式(2)所示。或者NR-liteUE仍然使用原有的规则,即表达式(1),只是对于
Figure PCTCN2020098273-appb-000021
的取值不再设置为0,可以设置为其他数值。
方法三:给NR-liteUE与非NR-liteUE配置不同的随机接入响应窗。可以配置不同的N值与不同的X值。
方法四:针对不同的RAR PDCCH使用不同的RA-RNTI。
要点二:在要点一的基础上,NR-lite的RAR PDCCH所配置的聚合程度和/或对应的PDCCH的候选传输位置可以不同。
要点三:针对非NR-liteUE与NR-liteUE,传输RAR的PDSCH不同。
要点四:是否给非NR-liteUE与NR-liteUE使用不同的RAR传输过程可以由基站进行配置或者根据其他条件进行决定。
比如,当基站给NR-liteUE配置独立的RAR传输过程,即配置独立如要点一中传输RAR PDCCH的传输参数时,则NR-liteUE使用独立的RAR接收流程。如果基站没有给NR-liteUE额外配置参数,用户则默认为使用与非NR-liteUE相同的接收流程。
比如,当初始(initial)WP的带宽等于CORESET#0的带宽,那么此时就默认NR-liteUE可以与非NR-liteUE使用相同的RAR接收流程。
要点四:基站端可以通过特定的随机接入前导码来区分是正常的NR-liteUE可以与非NR-liteUE。在相同的PRACH时频资源上,NR-liteUE所使用的随机接入前导与非NR-liteUE不同。
