为了便于理解本申请实施例,下面先介绍以下技术点:
一、信号放大器
信号放大器(或者称为智能信号放大器)用于扩展小区的覆盖范围,包括接收和放大来自上游基站的下行信号,使得到达终端(比如用户终端(User Equipment,UE))的信号强度增加;放大来自UE的上行信号,使得自UE到上游基站的上行信号的强度增加。
信号放大器可以接收来自上游基站的控制,即基站可以控制信号放大器的发送参数,例如信号放大器的开关和发送波束等,以提高信号放大器的工作效率和降低干扰。如图1所示网络结构中,包含3个网络节点,中间网络节点是一种信号放大器,其包含一个终端模块(或者称为移动终端(Mobile Termination,MT))和一个中继单元(Repeater Unit,RU),不排所述信号放大器只包含MT或RU中一个模块。其中MT可以与上游基站建立连接,基站通过MT与信号放大器交互控制信令,可以指示信号放大器的MT/RU的发送/接收相关参数。
二、定时提前(Timing Advance,TA)
参见图2,UE向基站发送信号时,信号的发送定时需要相对于其接收定时提前一段时间(TA时间),以便发送信号经过空口时延到达基站侧后,和基站的上下行定时对齐。
UE定时提前由协议规定的步骤获取。UE进行下行同步后,根据下行定 时发送物理随机接入信道(Physiacal Random Access Channel,PRACH),基站根据PRACH的接收/测量初步确定UE的定时提前量,并通过随机接入响应(Random Access Response,RAR)中的TA域将定时提前量通知到UE。另外,基站还可以通过媒体接入控制层(Media Access Control,MAC)控制单元(Control Element,CE)调整TA值。
另外,UE可配有多个TA组(TA group,TAG),一个或多个载波单元(Component Carrier,CC)可属于一个TAG,每个TAG中包含一个TA值。对于配有多个CC的UE,可以支持多个TA值,分属于不同的CC,可实现UE到不同位置的基站接收天线的传输。
另外,UE的TA会出现失步的情况,基站为UE配置失步定时器(timer),timer倒计时后,UE判定为上行失步。上行失步后,UE可发送PRACH进行重新同步。
三、循环前缀(Cyclic prefix,CP)
由于多径效应,信号传输到达接收端的时延不同,这样会造成码间干扰。CP技术通过正交复用(Orthogonal Frequency Division Multiplexing,OFDM)符号的特性,在有用OFDM符号前添加CP扩展,这样多径时延间的差值小于CP长度的情况下,就能消除码间干扰。
网络中部署了信号放大器后(或者网络中配置了多个分布式接收天线后),多径间的时延差别会较大,CP长度无法抵消多径时延效应。UE的冲激响应时延示意图如图3所示,信号放大器路径(图中示意为repeater path)为信号通过信号放大器后的路径,其他路径为不通过信号放大器的路径。Repeater path是不能不CP长度覆盖的,所以repeater path和其他path间会造成码间干扰。其中,LoS为视距(Line of Sight),NLoS为非视距(Non Line of Sight)。
参见图4,图中示出本申请实施例可应用的一种无线通信系统的示意图。无线通信系统包括终端41、信号放大器42和网络侧设备43。其中,终端41也可以称作终端设备或者用户终端(User Equipment,UE),终端41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)、可穿戴式设备(Wearable Device)或车载设备(Vehicle User Equipment,VUE)、行人终端(Pedestrian User Equipment,PUE)等终端侧设备,可穿戴式设备包括:智能手表、手环、耳机、眼镜等。需要说明的是,在本申请实施例并不限定终端41的具体类型。
网络侧设备43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 TransceiverStation,BTS)、无线电基站、无线电收发机、基本服务集(BasicServiceSet,BSS)、扩展服务集(ExtendedServiceSet,ESS)、B节点、演进型B节点(Evolved Node B,gNB)、家用B节点、家用演进型B节点、无线局域网(Wireless Local Area Network,WLAN)接入点、WiFi节点、发送接收点(Transmitting Receiving Point,TRP)、无线接入网节点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,所述基站不限于指定技术词汇,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。

下面结合实施例一、实施例二和实施例三介绍本申请的实施方式。
实施例一:下行同步
在本申请实施例中,可以设置多套定时,不同路径的传输采用不同的定时,以克服多径时延不能被CP抵消的情况。尤其针对FR2频率上的信号传输,不同路径的传输对应不同的波束(beam)方向的传输,基站和终端间可同时维持多个传输路径,以便提高传输的鲁棒性。
参见图7和图8,控制节点和终端间可以同时维持2条传输路径,传输路径1是控制节点-信号放大器-终端,终端通过接收定时#1接收传输路径1上的信号;传输路径2是控制节点-反射面-终端,终端通过接收定时#2接收传输路径2上的信号。
(1)下行接收定时获取
UE采用传统的(legacy)同步流程确定下行接收定时,但UE可根据下行参考信号的强度,维持/使用多个下行接收定时(例如,每个CC/每个TAG包括多个TA)。例如,下行辅同步信号(Secondary Synchronization Signal,SSS)/主同步信号(Primary Synchronization Signal,PSS)解调相关峰值较高的一个或多个时刻作为下行接收定时的参考时刻。
(2)下行接收定时上报
在本申请实施例中,UE可维持/使用多个下行接收定时,UE上报所述多个下行接收定时的相关信息。
可选地,UE上报的多个下行接收定时的相关信息能够反映多个下行接收定时之间的定时差值,以便辅助控制节点调度。即,控制节点避免UE接收不同传输时,因采用不同的下行接收定时而发生资源碰撞。
参见图9,终端接收时隙1(slot 1)和时隙2(slot 2)时,下行接收定时相对于控制节点下行发送定时的偏移量不同造成slot1和slot2间的接收冲突。
可选地,UE上报控制节点下行波束时,同时携带该下行波束方向上的多 个下行接收定时的相关信息。
(3)下行传输
UE同时维持多个下行接收定时的情况下,某下行传输(例如物理下行共享信道(Physical Downlink Shared Channel,PDSCH)/物理下行控制信道(Physical Downlink Control Channel,PDCCH)对应的下行接收定时的确定方式包括以下之一:
a、UE盲检多个下行接收定时;
b、下行接收定时的相关信息与下行波束存在对应关系,配置/调度/激活信令指示下行波束也意味着指示该下行接收对应的定时。
实施例二:上行同步
在本申请实施例中,通过设置多套发送定时(或者称为定时提前(Timing Advance,TA))的方式解决所述多径问题,不同路径的传输采用不同的TA,以克服多径时延不能被CP抵消的情况。
(1)初始TA
步骤1:UE根据下行同步,确定参考定时,并根据参考定时发送PRACH。
可选地,参考定时为UE下行接收定时中的一个。
可选地,参考定时在设定时间段内不能改变。例如,判定上行失步前不能改变该参考定时。
步骤2:控制节点检测PRACH,确定TA值(TA值可为多个值,每个CC/每个TAG包括多个TA),并通知该TA值到UE。
可选地,RAR(即增强RAR)中可以携带多个TA值。
可选地,RAR之外的信令(例如通过下行控制信息(Downlink Control Information,DCI)/媒体接入控制层(Medium Access Control,MAC)控制单元(Control Element,CE)/无线资源控制(Radio Resource Control,RRC)等)通知多个TA值(传统RAR仅携带一个TA值)。
步骤3:UE初始上行传输时(例如消息3(MSG3)或消息B(MSGB)),根据参考定时和/或RAR通知的TA进行传输。
可选地,如果RAR通知多个TA,UE选择一个TA进行初始上行传输
(a)任选一个TA;
(b)特定的TA,例如最小的TA/最大的TA等;
(c)RAR信令中的第一个TA等。
(2)TA调整。
闭环调整一个或多个上述TA。例如,通过MAC CE指示TA的调整值,调整值调整TA的方式包括以下之一:
(a)统一调整所有TA(可适用于移动中继器(mobile repeater))
(b)分别调整TA。例如,一个调整值对应一个或多个TA值
可选地,调整值和TA间存在关联关系,显示/隐式地关联调整值和对应的TA。例如,为TA设定索引(index),调整信令中指示调整值对应的TA的index
(3)发送波束训练
发送波束训练,确定发送波束和其关联的发送定时(TA)。
可选方式1:UE按照预设的TA进行SRS发送,控制节点采用不同的接收定时盲检某个发送波束方向上SRS,以便确定所述上行波束关联的TA值
例如,1)控制节点配置SRS资源集合;2)假设UE在不同的SRS资源上采用不同的发送波束进行SRS发送;3)规定UE采用同样的预设TA在所述SRS资源集合上发送SRS。
可选地,预设的TA受控制节点控制(例如,配置SRS资源集合时指示的预设的TA等)。
可选方式2:UE采用不同的预设的TA实现SRS在某个发送波束方向上的发送,控制节点按照一种接收定时检测SRS,以便确定所述发送波束关联的TA
例如,参见图10,1)控制节点配置多个SRS资源集合;2)假设UE在一个SRS资源集合中不同的SRS资源上采用不同的发送波束进行SRS发送,且不同SRS资源集合上,相同SRS资源编号的资源上发送的SRS波束方向重复;3)UE采用不同的预设的TA在不同的SRS资源集合上发送SRS。
可选地,控制节点解调多个SRS资源集合,分别确定每个SRS传输资源(或波束方向)对应的TA。
可选地,UE在每个SRS资源集合上传输的TA受控制节点控制。
例如,配置SRS资源集合时指示的所述TA;为多个TA设定index,TA的index与SRS资源集合的index存在映射关系。
可选地,控制节点确定发送波束和其关联的发送定时(TA)之后,将关联关系通知给UE。
(4)上行传输
UE同时维持多个TA的情况下,某上行传输(例如,物理上行共享信道(Physical Uplink Shared Channel,PUSCH)/物理上行控制信道(Physical Uplink Control Channel,PUCCH))对应的TA的确定方式包括以下之一:
a、配置信令(例如配置授权(configured grant,CG)类型(type)1/2的配置信令等)/调度信令(例如动态授权(dynamic grant,DG)的调度信令)/激活信令(例如CG type 2的激活信令)直接指示传输对应的TA;
b、TA与上行波束存在对应关系,配置/调度/激活信令指示上行波束也意味着指示该上行传输对应的发送定时。
可选地,上述方法适用于上行接收波束训练。即,对于上行接收波束训练的SRS资源集合上的SRS传输。
(5)接收波束训练(训练方式可参考发送波束训练)
UE同时维持多个TA的情况下,对于接收波束训练,SRS发送的TA的确定方式包括以下之一:
a、配置/调度/激活直接指示所述SRS发送对应的TA
b、TA与接收波束存在对应关系,配置/调度/激活信令指示接收波束也意味着指示该SRS发送对应的发送定时。

可选地,Timer倒计时的TA值为无效TA。
如图11所示,第三段Timer到计时后TA无更新,则该TA在第三段Timer倒计时后失效。
可选方式2:所有的TA值共用一个判定Timer,Timer到计时后重置。
可选方式2-1:Timer倒计时前,针对所有TA,UE都没有对应的定时(Timing)指示信令,上行失步,可触发PRACH发送。
可选方式2-2:Timer倒计时前,存在某个或某些TA,UE没有对应的Timing指示信令,上行失步,可触发PRACH发送。
可选方式2-3:Timer倒计时前,存在某个或某些TA,UE没有对应的Timing指示信令,所述某个或某些TA达到预设数量后,上行失步,可触发PRACH发送。
可选地,Timer倒计时后,没有更新的TA为无效TA。如图12所示,在第三段Timer倒计时前TA无更新,则该TA在第三段Timer倒计时后失效。
实施例三:上行同步
UE根据控制节点指示的TA和多个DL接收定时的定时差,确定多个上行传输的TA值。
可选地,UE以某个DL接收定时为参考,计算其他接收定时与该参考定时之间的定时差值,所述定时差值的个数取决于其他接收定时的个数。
可选地,UE的最终确定多个TA,包括以下一项或多项:

(b)TA2:控制节点指示的TA和其中一个定时差值之和;
(c)TA3:控制节点指示的TA和其中另一个差值之和;
(d)以此类推所有TA值,即TA4,…,TAn。
可选地,UE根据其中一个接收定时做TA(例如参考定时)。
实施例四:上行同步
参见图13a和图13b,UE将DL路径#m的DL接收定时作为参考定时,确定UL路径#a的TA为TA_m-a;UE将DL路径#n的DL接收定时作为参考定时,确定UL路径#b的TA为TA_n-b。
当UE根据DL路径#m的DL接收定时确定UL路径#b的TA时,TA_m-b=(TA_m-a+TA_n-b)/2。
同理TA_n-a=(TA_m-a+TA_n-b)/2。
在上述实施例中,UE能否同时维持多个发送/接收定时(timing),可以作为UE的能力上报到控制节点。
在上述实施例中,UE能否同时使用多个定时进行接收/发送,或者UE分时使用多个定时进行接收/发送(同一时间使用一个定时),可以作为UE的能力上报到控制节点。
控制节点使用不同定时对应的路径(或波束)进行空分复用调度,或者在某些定时对应的路径(或波束)发生遮挡时进行路径(或波束)切换。
