本申请主张在2019年8月16日在中国提交的中国专利申请号No.201910760451.8的优先权,其全部内容通过引用包含于此。
技术领域
本公开涉及通信技术领域,特别是指一种数据传输方法、装置、终端及基站。
背景技术
对于URLLC(超可靠、低时延通信)业务的需求主要有几种典型应用场景,包括AR(增强现实)或VR(虚拟现实)的娱乐工业、工业自动化、远程驾驶在内的交通控制需求,以及电力分布控制需求等。这些URLLC业务有着对可靠性、时延以及性能等方面的更高要求。在R16(3GPP协议版本16)研究阶段,基于多TRP/PANEL(传输点或面板)间的多点协作传输技术的应用,有望更好的提升URLLC的传输性能,具体介绍如下:
1)multi(多)-TRP/PANEL传输技术
基站多TRP/PANEL的应用主要为了改善小区边缘的覆盖,在服务区内提供更为均衡的服务质量,用不同的方式在多个TRP/PANEL间协作传输数据。从网络形态角度考虑,以大量的分布式接入点加基带集中处理的方式进行网络部署将更加有利于提供均衡的用户体验速率,并且显著的降低越区切换带来的时延和信令开销。在高频段,每个TRP的天线阵可以被分为若干相对独立的天线面板,整个阵面的形态和端口数都可以随部署场景与业务需求进行灵活的调整。而天线面板或TRP之间也可以由光纤连接,方便进行更为灵活的分布式部署。利用多个TRP或面板之间的协作,从多个角度的多个波束进行传输或接收,可以更好的克服各种遮挡或阻挡效应,保障链路连接的鲁棒性,适合URLLC业务提升传输质量和满足可靠性要求。
2)基于多点协作传输的URLLC增强方案
根据可能采用的基于多点协作传输的URLLC增强方案包括以下几种:
方案1(空分复用(Space Division Multiplexing,SDM)):在一个时隙slot内重叠的时频资源上,每个传输机会(transmission occasion,实际上指一个TRP在一份资源上发送的信号)对应于所关联的一个传输配置指示(Transmission Configuration Indicator,TCI)状态(state)以及一组对应于DMRS(解调参考信号)端口的数据;
方案2(频分复用(Frequency Division Multiplexing,FDM)):在一个slot内,每一份频域资源都关联到一个TCI(传输配置指示)state(状态),各份频域资源之间互不重叠;
方案3(小时隙(mini-slot)级别的时分复用(Time Division Multiplexing,TDM)):在一个slot内,每一份时域资源都关联到一个TCI state,各份时域资源之间互不重叠;其中一份时域资源指一组(每组中可以只有一个)mini slot;示例如图1所示(代表第N次传输时机的基于mini-slot(小时隙)的数据传输)。
方案4(slot级别的TDM):每一份时域资源都关联到一个TCI state,各份时域资源之间互不重叠;其中一份时域资源指一组(每组中可以只有一个)slot;示例如图2所示(代表第N次传输时机的基于时隙(slot)的数据传输)。
以上方案之间还可以进一步进行组合,例如FDM+TDM方式。
但是,对于方案3和4(TDM方式),还无法明确确定在多个TRP/PANEL上传输的冗余版本RV和传输时机之间的映射关系,以及具体的信令定义,导致无法配置终端与基站之间的数据传输。

针对上述技术问题,本公开的一些实施例提供了一种数据传输方法,能够实现在多TRP/PANEL间协作传输时,对于利用TDM方式来支持可靠性的传输方案下,进一步通过资源交织映射的方法来提高传输可靠性。
具体的,下面对RV对应到不同的时域传输时机的方法(支持mini-slot或slot的发送)进行举例说明,关于循环使用所述RV基本序列中的各个RV,以下以顺序循环为例:
示例1-1:预先定义用于单个TRP传输的RV序列集合{s1,s2,…,sm},包含m个长度为k的RV序列。假设k为4,如每个RV序列为s{rv1,rv2,rv3,rv4}可以是{0,2,3,1},{0,3,0,3},{0,2,0,2},…,{0,0,0,0}之一。
(1)基站通过高层信令或者DCI信令向终端分别指示2个RV序列的序号,即REP_RV1和REP_RV2,分别对应TCI state0和TCI state1的TRP使用的RV基本序列,例如高层信令指示方式可如下:
REP-RV1 ENUMERATED{s1-0231,s2-0303,…,sn-0000}OPTIONAL,--Need R
REP-RV2 ENUMERATED{s1-0231,s2-0303,…,sn-0000}OPTIONAL,--Need R
基站和终端均可根据预设对应关系,确定高层信令指示的RV基本版本,比如当REP_RV1指示了0,则具体选择了{0,2,3,1}作为TCI state0的RV基本序列,RV2同理。
如果REP_RV2或者REP_RV1信令指示缺省,而实际配置了两个TCI state,则可默认REP_RV2和REP_RV1相同。
(2)基站或终端通过RV基本序列得到实际用于对应不同TCI state传 输的RV序列(即RV1和RV2),需要知道RV序列中的起始位置,从而循环映射到对应TCI state的相应传输时机,具体的,可采用如下方式:
a)基站与终端之间约定首次传输起始于周期内关联rv=X的序列位置开始循环rv发送序列,例如,假设X=0,定义的RV基本序列为{3,1,0,2},则实际发送序列为{0,2,3,1};
b)基站通过高层信令或者DCI比特向终端指示初始发送的RV index 1以及RV index 2,实际RV序列从RV index位置开始循环,例如,基本序列指示为{0,2,3,1},index=1,则,实际RV序列为{2,3,1,0}(index的取值位大于或等于0,且小于或等于3的整数);
如果RV index2信令指示缺省,可默认两个RV index相同。
(3)基站或终端可通过得到的RV发送序列RV1和RV2,分别把RV1映射到K个传输时机内TCI state 0对应的传输时机上,并循环顺序使用RV1对应的rv1#n版本(RV1序列中的各个版本),把RV2映射到K个传输时机内TCI state 1对应的传输时机上并顺序循环使用RV2对应的rv2#n版本。
具体的,第n(n=1,2,…,K)个传输时机关联的rv可由对应的REP_RV序列中的第[mod(n-1,4)+RV index+1]个值确定。
基站与终端可采用相同的方式进行关于RV与传输时机对应关系的确认,在此不再赘述。
示例1-2:预先定义用于单个TRP传输的RV序列集合{s1,s2,…,sm},包含m个长度为k的RV序列。假设k为4,如每个RV序列为s{rv1,rv2,rv3,rv4}可以是{0,2,3,1},{2,3,1,0},{3,1,0,2},{1,0,2,3},{0,3,0,3},{0,2,0,2},…,{0,0,0,0}之一,即有可能包含了同一个RV基本序列自身循环的不同版本。
(1)基站通过高层信令或者DCI信令向终端分别指示2个RV序列的序号,即REP_RV1和REP_RV2,分别对应TCI state0和TCI state1的TRP使用的RV序列。
如果REP_RV2信令指示缺省,而实际配置了两个TCI state,则可默认REP_RV2等于REP_RV1。
(2)直接使用信令指示的RV即REP_RV1和REP_RV2,对应各自的 TCI state顺序循环映射到K个传输时机上。
这样不同TRP的RV序列分别对应到各自的时域传输时机,考虑到同一个TRP经历的衰落信道具有连续性,能够实现对于每个TRP上的传输RV序列最优,有利于获得更高的合并增益。
假设4小于K,则第n(n=1,2,…,K)个传输时机关联的rv可由对应的REP_RV序列中的第[mod(n-1,4)+1]个值确定。
基站与终端可采用相同的方式进行关于RV与传输时机对应关系的确认,在此不再赘述。
如果不考虑不同RV序列和TRP的独立映射关系(即不考虑TCI state),则RV对应到不同的时域传输时机的方法,举例如下:
示例2-1:预先定义用于单个TRP传输的RV序列集合{s1,s2,…,sm},包含m个长度为k的RV序列。假设k为4,如每个RV序列s{rv1,rv2,rv3,rv4}可以是{0,2,3,1},{0,3,0,3},{0,2,0,2},…,{0,0,0,0}之一。
(1)基站可通过高层信令或者DCI信令通知终端选择一个RV序列的序号,即REP_RV。
(2)基站可通过高层信令或者DCI信令向终端配置一个循环起始位置的序号,即RV index。
(3)终端可在基站通过高层信令配置的K个传输时机内,循环应用从RV index开始的RV序列值,第n(n=1,2,…,K)个传输时机关联的rv可由配置的REP_RV序列中的第[mod(n-1,4)+RV index+1]个值确定。mod表示求余运算。
基站与终端可采用相同的方式进行关于RV与传输时机对应关系的确认,在此不再赘述。
示例2-2:预先定义用于单个TRP传输的RV序列集合{s1,s2,…,sm},包含m个长度为k的RV序列。假设k为4,如每个RV序列s{rv1,rv2,rv3,rv4}可以是{0,2,3,1},{2,3,1,0},{3,1,0,2},{1,0,2,3},{0,3,0,3},{0,2,0,2},…,{0,0,0,0}之一,即有可能包含了同一个RV基本序列自身循环的不同版本。
(1)基站可通过高层信令或者DCI信令通知终端选择一个RV序列的序 号,即REP_RV。
(2)终端可在基站通过高层信令配置的K个传输时机内,循环应用从RV index开始的RV序列值,假设4小于K,则第n(n=1,2,…,K)个传输时机关联的rv可由配置的REP_RV序列中的第[mod(n-1,4)+1]个值确定。
基站与终端可采用相同的方式进行关于RV与传输时机对应关系的确认,在此不再赘述。
示例3-1:预先定义用于协作的2个TRP传输的RV序列集合{s1,s2,…,sm},包含m个长度为k的RV序列。假设k大于或等于K,K个rv可以和K个传输时机一一对应。
(1)基站可通过高层信令或者DCI信令通知终端选择一个RV序列的序号,即REP_RV。
(2)终端可在基站通过高层信令配置的K个传输时机内,和REP_RV对应的RV序列值一一映射,第n(n=1,2,…,K)个传输时机关联的rv可由配置的REP_RV序列中的第n个值确定。
基站与终端可采用相同的方式进行关于RV与传输时机对应关系的确认,在此不再赘述。
示例3-2:预先定义用于协作的2个TRP传输的RV序列集合{s1,s2,…,sm},包含m个长度为k的RV序列。假设k大于或等于K,K个rv可以和K个传输时机一一对应。
(1)基站可通过高层信令或者DCI信令通知终端选择一个RV序列的序号,即REP_RV。
(2)基站可通过高层信令或者DCI信令向终端配置一个循环起始位置的序号,即RV index。
(3)终端可在基站通过高层信令配置的K个传输时机内,循环应用从RV index开始的RV序列值,和REP_RV对应的RV序列值一一映射,具体的,第n(n=1,2,…,K)个传输时机关联的rv可由配置的REP_RV序列中的第[mod(n-1,K)+RV index+1]个值确定。
基站与终端可采用相同的方式进行关于RV与传输时机对应关系的确认,在此不再赘述。
针对上述示例1-1和1-2中TCI state和传输时机之间的对应关系,介绍如下:
对于单个TRP的TDM传输方式,同一个传输块TB块在多个时间(min-slot/slot)上重复发送,不同的传输时机(transmission occasion)可以对应同一TB块的相同或者不同的RV(冗余版本),接收端(终端)需要对于相同或者不同的RV版本在译码前进行软合并,从而得到更高的编码增益。
假设网络侧(基站)指示或配置了时域重复次数为M(对于图1所示方案3,对应于M个mini slot;对于图2所示方案4,对应于M个slot),DMRS对应的QCL通过TCI codepoint(指示信息)给出,对应1个或者2个TCI state,2个TCI state时分别对应不同的波束方向指示(可以是指相同的TRP的不同的波束方向指示,也可以是指不同的TRP的波束方向指示,一个TCI state指示一个TRP上波束发送)。其中TCI codepoint对应的指示只包含一个TCI state时,可为TCI state 0或者TCI state 1;如果包含两个TCI state(TCI state 0和TCI state 1)时,可以同时指示来自于两个TRP的波束方向的TCI state。TCI state可以通过一定的方式与时域上的不同传输时机相对应,比如:
方式一:通过长度为S的bitmap(比特图)或者高层信令指示对应TCI序列在TCI序列表格中的序列号来实现和时域上的传输时机一一对应的映射。
方式二:通过预定义来定义TCI state与时域传输时机的对应方式,如可以约定TCI state 0对应于编号为偶数的mini slot或slot,TCI state 1对应于编号为奇数的mini slot或slot;可以约定TCI state 0对应于前一半mini slot或slot,TCI state 1对应于后一半mini slot或slot。确定了重复次数N(小于或等于M)之后,网络侧可以通过以上约定确定TCI state与各个mini slot或slot的对应关系。
通过上面的指示,可以得到时域传输时机和QCL指示的TCI state的具体对应关系,即对应传输时机{T1,T2,…,Tk},所对应的的TCI state序列为{TCI state(T1),TCI state(T2),…,TCI state(Tk)},如M=4,TRP在传输时机上奇偶交错发送时,则对应传输时机{T0,T1,T2,T3}的TCI state序列为{TCI state0,TCI state1,TCI state0,TCI state1}。
由上可知,本公开的一些实施例提供的方案能够实现不同传输时机与使 用的RV版本相关联,关联方法可以考虑单独TRP的独立映射,也可以考虑TRP间RV版本的联合映射;从而在基于多点传输的TDM可靠性增强方案(图1所示方案3或图2所示方案4)中,可以确定对于不同的传输时机所使用的RV版本的关联关系,以及TCI state与mini slot或slot的对应关系,保证基站与终端之间的数据传输。
