具体实施方式
下面将结合本发明实施例中的附图,对本发明实施例中的技术方案进行清楚、完整地描述,显然,所描述的实施例是本发明一部分实施例,而不是全部的实施例。基于本发明中的实施例,本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其他实施例,都属于本发明保护的范围。
本发明提供的技术方案可以应用于各种通信系统,例如,5G通信系统,未来演进系统或者多种通信融合系统等等。可以包括多种应用场景,例如,机器对机器(machine to machine,M2M)、D2M、宏微通信、增强型移动互联网(enhance mobile broadband,eMBB)、超高可靠性与超低时延通信(ultra reliable&low latency communication,uRLLC)以及海量物联网通信(massive machine type communication,mMTC)等场景。这些场景包括但不限于:终端与终端之间的通信,或网络设备与网络设备之间的通信,或网络设备与终端间的通信等场景中。本发明实施例可以应用于与5G通信系统中的网络设备与终端之间的通信,或终端与终端之间的通信,或网络设备与网络设备之间的通信。
本发明实施例所涉及的通信系统包括至少一个网络设备以及每个网络设备所连接的一个或多个终端。
其中,上述的网络设备可以为基站、核心网设备、传输节点(Transmission Reference Point,TRP)、中继站或接入点等。网络设备可以是全球移动通信系统(Global System for Mobile communication,GSM)或码分多址(Code Division Multiple Access,CDMA)网络中的基站收发信台(Base Transceiver Station,BTS),也可以是宽带码分多址(Wideband Code Division Multiple Access,WCDMA)中的NB(NodeB),还可以是LTE中的eNB或eNodeB(evolutional NodeB)。网络设备还可以是云无线接入网络(cloud radio access network,CRAN)场景下的无线控制器。网络设备还可以是5G通信系统中的网络设备或未来演进网络中的网络设备。
终端可以为无线终端也可以为有线终端,该无线终端可以是指向用户提供语音和/或其他业务数据连通性的设备,具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5G网络中的终端或者未来演进的PLMN网络中的终端等。无线终端可以经无线接入网(Radio Access Network,RAN)与一个或多个核心网进行通信,无线终端可以是移动终端,如移动电话(或称为“蜂窝”电话)和具有移动终端的计算机,例如,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言和/或数据,以及个人通信业务(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,无线终端也可以为移动设备、用户设备(User Equipment,UE)、终端终端、接入终端、无线通信设备、终端单元、终端站、移动站(Mobile Station)、移 动台(Mobile)、远程站(Remote Station)、远方站、远程终端(Remote Terminal)、订户单元(Subscriber Unit)、订户站(Subscriber Station)、用户代理(User Agent)、终端装置等。上述仅仅是一种示例,实际应用中不限于此。
下面对本发明中所涉及的部分术语进行解释,以方便读者理解:
1、关于波束测量和报告(beam measurement and beam reporting)
模拟波束赋形是全带宽发射的,并且每个高频天线阵列的面板上每个极化方向阵元仅能以时分复用的方式发送模拟波束。模拟波束的赋形权值是通过调整射频前端移相器等设备的参数来实现。目前在学术界和工业界,通常是使用轮询的方式进行模拟波束赋形向量的训练,即终端每个天线面板每个极化方向的阵元以时分复用方式依次在约定时间依次发送训练信号(即候选的赋形向量),供网络侧或者终端侧在下一次波束训练或者传输业务时采用该训练信号来指示。
2、关于下行波束指示(beam indication)
基于上述波束测量和波束报告,网络侧选择相应的波束进行信号发送,同时指示终端相应的波束信息,终端依赖该波束指示(Beam indication)进行信号接收。目前该波束指示已经同意在物理层控制信道中动态指示。
3、关于上行波束指示(SRI或CRI)
上行波束指示是指网络侧对终端使用的上行波束的指示。该指示在上行波束训练与上行传输过程中都需要使用。目前讨论的上行波束训练过程包括U1,U2,U3。U1过程表示进行UL收发波束的初步训练,U2表示进行UL发波束的精细训练,U3表示进行UL收波束的精细训练。
在U2与U3过程中,网络侧会利用已知的信息通知终端发送相应的波束。例如通过U1过程,网络侧已经初步获知终端端哪个面板对应的上行发送较好。在U2过程中,通过SRI指示终端在对应面板上发送不同的波束,进行更精细的发送波束训练;在U3过程中,同样可以通过SRI指示终端在这些面板上发送多个波束,便于收端进行收波束的训练。
在网络存在对称性的情况下,可以使用CRI信息来隐含指示相应的上行波束信息。
4、关于上行传输方式
现在的上行传输方式分为两类,一类是基于码本的传输方案(codebook based transmission),一类是基于非码本的传输方案(non-codebook based transmission)。Codebook based transmission时,网络会按照事先约定的码本向终端指示对应的码字,终端按照网络的指示进行多天线预编码并进行上行传输,Non-codebook based transmission时,网络会给终端指示对应的SRS index(SRI),终端根据SRS所采用的预编码决定实际数据传输对应的预编码。
5、其他术语
本文中术语“和/或”,仅仅是一种描述关联对象的关联关系,表示可以存在三种关系,例如,A和/或B,可以表示:单独存在A,同时存在A和B,单独存在B这三种情况。另外,本文中字符“/”,一般表示前后关联对象是一种“或”的关系;在公式中,字符“/”,表示前后关联对象是一种“相除”的关系。如果不加说明,本文中的“多个”是指两个或两个以上。
为了便于清楚描述本发明实施例的技术方案,在本发明的实施例中,采用了“第一”、 “第二”等字样对功能或作用基本相同的相同项或相似项进行区分,本领域技术人员可以理解“第一”、“第二”等字样并不对数量和执行次序进行限定。
需要说明的是,本发明实施例中,“示例性的”或者“例如”等词用于表示作例子、例证或说明。本发明实施例中被描述为“示例性的”或者“例如”的任何实施例或设计方案不应被解释为比其它实施例或设计方案更优选或更具优势。确切而言,使用“示例性的”或者“例如”等词旨在以具体方式呈现相关概念。
实施例一:
图1示出了本发明提供的一种信号传输方法的流程示意图。该方法具体包括:
S201、终端向网络设备发送第一指示信息。
其中,第一指示信息用于向网络设备指示终端的能力信息,并具体指示以下至少一种:终端所需的第一SRS资源集数量,一个第一SRS资源集中第一SRS资源的数量,终端的上行多天线传输的最大层数,终端的上行传输通道间是否相位相干,PTRS最大端口数量,第一指示信息用于指示网络设备确定第二指示信息,第二指示信息用于指示终端发送SRS信号。
上述的终端的上行传输通道间是否相位相干包括以下三种:终端的上行传输通道间全部相位相干(Fully coherent),即终端的所有的RF通道都是相位相干的,终端的所有上行传输通道间全部相位不相干(Non-coherent),即终端的所有RF通道都是相位不相干的,终端的上行传输通道间部分相位相干(部分相干),即终端的部分RF通道是相干的,例如1和3是相干的,2和4是相干的。对于部分相干,可以根据预先约定的规则认为哪些端口是相位相干的。
S202、网络设备根据第一指示信息向终端发送第二指示信息。
S203、终端根据第二指示信息发送SRS信号。
示例性的,终端向网络设备发送的第一指示信息中所指示的终端能力信息时,可以直接显性指示,即将具体的终端能力信息包含在第一指示信息中发送至网络设备,也可以隐性指示,即可以基于上述的5种能力信息中的至少一个隐性的指示其他能力信息。
1)、对于第一SRS资源集数量:
该第一指示信息可以直接包含该第一SRS资源集数量,也可以通过其他终端能力信息隐性指示,例如,终端需要的SRS resource set数量与终端的天线面板(panel)一一对应,例如,终端天线panel数量为2时,SRS resource set数量为2。
2)对于第一SRS资源集中的第一SRS资源的数量:
该第一指示信息可以直接包含该第一SRS资源集中第一SRS资源的数量,也可以通过其他终端能力信息隐性指示,具体如何指示可参照如下示例:
示例1:第一指示信息具体用于指示终端的一个天线面板所需的模拟波束数量,该模拟波束数量用于指示第一SRS资源的数量,一般的,每个resource set中的resource数量与每个天线panel需要的analog beam数量相同。
具体的,当终端所需的模拟波束数量信息存在分层结构,则该第一指示信息具体用于指示终端的一个天线面板所需的模拟波束数量,该第一指示信息包括以下至少一个:天线面板的所有模拟波束层的总模拟波束数量,天线面板的每个模拟波束层所需的模拟波束数量,以及天线面板的第一模拟波束层的模拟波束数量,该第一模拟波束层为天线面板的所 有模拟波束层中模拟波束数量最大的模拟波束层。示例性的,终端在确定一个天线面板所需的模拟波束数量时可以根据终端自身的analog beam层级关系上报,该终端天线的波束层级包括两层,第一层级包括波束0和波束5,第二层级包括波束1~4和6~9,终端在具体上报时,可以通过标准化提前约定好是上报所有层级加起来的波束数量(如每个panel为5个波束),还是波束数量最大的层级需要的波束数量(如每个panel为4个波束),或者是各个层级分别需要的波束数量(第一层级需要的波束数量为1、第二层级需要的波束数量为4)。
示例2:第一指示信息具体用于指示第一SRS资源的数量,第一SRS资源的数量用于指示模拟波束数量。
3)、对于终端的上行多天线传输的最大层数或每个天线面板的层数:
终端的上行多天线传输的最大层数用于表示终端的上行数据通道总的数量,每个天线面板的层数用于表示每个天线面板的数量。终端可以通过第一指示信息直接上报最大层数,从而隐性的向网络设备上报终端的上行数据通道总的数量,通过第一指示信息直接上报每个天线面板的层数,从而可隐性上报每个天线面板的数量,相反的,终端可以通过第一指示信息直接上报终端的上行数据通道总的数量,从而隐性的向网络设备上报最大层数,通过第一指示信息直接上报每个天线面板的数,从而可隐性上报量每个天线面板的层数。
如果终端上报的是每个天线面板的数量,可以通过每个天线面板的数量与上报的第一SRS资源的数量相乘得到第一SRS资源的数量。
此外,终端的上行多天线传输的最大层数或每个天线面板的层数,还可以通过其他终端能力信息按照预先约定的规则隐式得到。
4)、对于终端的上行传输通道间的相位信息

示例2:当网络设备为终端配置用于波束管理的第二SRS资源时:
1)、网络设备按照第一指示信息指示的第一SRS资源集的数量和每个第一SRS资源集内的第一SRS资源的数量进行资源配置。
2)、网络设备可以为每个第一SRS资源集配置一个第一SRS资源,此时终端假设使用最高层级的波束进行波束训练。
3)、网络设备如果按照第一指示信息指示的每个第一SRS资源集的最大资源数量配置,如果此时网络设备没有其他指示终端波束扫描行为的指示,此时终端对所有的波束都进行波束训练。
4)、网络设备如果按照终端上报的每个第一SRS资源集的最大资源数量配置,如果此时网络设备指示了进行波束重复,但并未指示对应的发送波束,此时终端按照最高层级的波束进行波束重复。
5)、网络设备如果按照终端上报的第一SRS资源集的最大资源数量配置,如果此时网络设备指示了进行波束扫描,但并未指示对应的发送波束,此时终端对所有的发送波束进行波束扫描,或者按照最低层级的波束进行波束扫描。
6)、网络设备还可以按照终端上报的层级波束信息进行资源配置,即当第一指示信息用于指示层级波束信息时,网络设备可以按照该层级波束信息进行资源配置。
示例性的,网络设备可以在配置SRS时指示终端进行预编码粒度,终端按照指示的粒度对SRS信号进行相应的预编码,如果网络设备没有指示或者未进行标准化或者未约定,则终端需要假设网络会按照连续分配的带宽进行信道估计。

上述第二指示信息用于指示终端按照预定的端口编号规则选择不同天线的端口发送上述SRS信号。
示例性的,如果第二SRS资源集内单个第二SRS资源的端口数大于1,则终端认为该第二SRS资源集中第二SRS资源用于码本传输方式上行传输信道获取信道信息获取。
示例1:通过标准限定第二SRS资源集内只有一个第二SRS资源,该第二SRS资源的端口数与最大层数相同。
示例2:对于该第二SRS资源集内的同一第二SRS资源不同的端口的波束数量,允许不同的端口使用不同的波束,可以通过多个SRI为同一个第二SRS资源的不同端口指示不同的波束。例如,网络设备给终端指示的波束数量与第一指示信息指示的第二SRS资源集数量相同;或者,终端上报的第二SRS资源集数量小于终端上报的最大层数时,指示的波束与对应的第二SRS资源端口之间的关系可以提前约定。

示例性的,终端在进行上行SRS传输时,需要按照事先约定的端口编号规则来放置不同天线的SRS信号。对于部分相干,例如可以提前约定端口1和端口3是相位相干的,端口2和端口4是相位相干的,终端在发送SRS时需要按照这一假设对相位相干的天线分别进行组合发送SRS。
可选的,上述第二指示信息用于指示第二SRS资源的端口数均为1,上述第一预定规则为将上述第二SRS资源标识为用于非码本传输方式上行传输信道获取信道信息的SRS资源;

进一步可选的,该排序的规则是预定义的规则,或网络设备配置的规则,该规则包括按照端口间的相位是否相干。
示例性的,若第二SRS资源集内每个第二SRS资源都只有一个端口,则终端认为该第二SRS资源集是用作non-codebook based transmission。
示例1:网络设备可以为该第二SRS资源集统一配置或者动态指示一个用于信道信息获取的CSI-RS,用于该第二SRS资源集内终端发送SRS时计算计算预编码向量(例如,预编码权值)。
示例2:网络设备可以为第二SRS资源集内的每个第二SRS资源分别配置或者动态指示一个发送波束。
示例3:终端在对SRS信号进行预编码时,仅仅在相位相干的天线之间进行预编码, 对于相位不相干的两个天线则不在一个resource内进行预编码。
示例4:终端在对预编码后的SRS信号进行上行传输时,根据之前上报的上行传输通道间的相位相干信息,以及最大层数对SRS传输进行排序。例如,如果是fully coherent或者是non-coherent,则没有特别的约定;如果是部分相干,则按照约定的顺序进行排序,可以是先排相干的,再排不相干的,例如,若最大层数是4,且部分相干,则终端发送的SRS中,SRI=1和SRI=2对应的SRS约定为是从同一组相干端口对中发出的,SRI=3和SRI=4对应的SRS约定为是从另一组相干端口对中发出的。

示例1:当网络配置终端最多有一个PTRS端口时,该端口与最低/最高/按照其他规则的DMRS端口关联(即采用相同的预编码)。
示例2:当网络配置终端最多有两个PTRS端口时,按照下述规则进行处理。
规则1:按照提前约定的规则确定哪些端口间可以使用相同的PTRS端口。
规则2:如果网络设备指示的TPMI对应的端口按照上述规则可以使用相同的PTRS端口,则使用一个PTRS端口;如果网络指示的TPMI对应的端口按照上述规则需要使用超过一个PTRS端口,则使用两个PTRS端口。例如,如果仅使用一个PTRS端口,则该PTRS端口与最低/最高/其他规则的DMRS端口关联;如果使用两个PTRS端口,则根据TPMI指示对DMRS端口进行分组,将能够共享一个PTRS端口的DMRS作为一组,PTRS分别与各组内编号最低/最高或按照其他规则的DMRS端口关联。

示例性的,对于部分相干的终端,如果网络配置的PTRS端口数大于1:
1)、如果是codebook based transmission,根据TPMI的指示确定相应的关联关系
示例1:如果是codebook based transmission,根据TPMI的指示确定相应的关联关系。例如,如果TPMI指示的传输对应的所有天线都在一个coherent端口pair内,则仅仅使用一个PTRS端口,该PTRS端口与最低的DMRS端口关联,此时,按照提前约定的规则确定哪些端口属于一个coherent端口pair。
示例2:如果TPMI指示的传输对应的端口多于一个coherent端口pair,则需要使用大于一个PTRS端口;如果TPMI指示的传输对应的端口都在一个coherent端口pair内则仅仅使用一个PTRS端口。例如,仅使用一个PTRS端口,则该PTRS端口与最低/最高/其他规则的DMRS端口关联,或者,如果使用两个PTRS端口s,则根据TPMI指示对DMRS端口进行分组,将对应一个coherent端口pair的DMRS端口作为一组,PTRS分别与各组内编号最低/最高或按照其他规则的DMRS端口关联。
2)、如果是non-codebook based transmission,根据提前约定/配置的规则确定不同SRI是否可以共享PTRS端口,进而决定需要几个PTRS端口,例如:
示例1:最大的layer数是4,partially coherent,则终端发送的SRS中,SRI=1和SRI=2对应的SRS约定为可以共享一个PTRS端口;SRI=3和SRI=4对应的SRS约定为是共享 另一个PTRS端口。
示例2:终端根据网络的SRI指示确定使用一个还是两个PTRS端口,例如网络触发的上行传输是2layer,对应的两个layer分别是SRI=1和SRI=2,则仅使用一个PTRS端口;如果网络触发的上行传输是2layer,对应的2个layer分别为SRI=1和SRI=4,则需要使用两个PTRS端口。
示例3:在各自的组合内,分别与编号最低的DMRS端口关联;如果网络触发的上行传输是4layer,DMRS端口=1~4分别与SRI=1~4对应,则需要使用两个PTRS端口,第一个PTRS端口与DMRS端口1对应,第二个PTRS端口与DMRS端口3对应。
