其中,DMRS,在LTE中用于PUSCH(PhysicalUplinkSharedChannel,上行物理共享信道)和PUCCH(Physical Uplink Control Channel,物理上行链路控制信道)的相关解调。
本公开实施例中,用户设备(User Equipment,UE)可以接收到网络设备发送的第一指示信息。
本公开实施例涉及的UE,可以为终端设备,可以是指向用户提供语音和/或数据连通性的设备,具有无线连接功能的手持式设备、或连接到无线调制解调器的其他处理设备等。无线终端设备可以经无线接入网(Radio Access Network,RAN)与一个或多个核心网(Core Network,CN)进行通信,无线终端设备可以是移动终端设备,如移动电话(或称为“蜂窝”电话)和具有移动终端设备的计算机,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。例如,个人通信业务(Personal Communication Service,PCS)电话、无绳电话、会话发起协议(Session Initiated 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。无线终端设备也可以称为系统、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(access point)、远程终端设备(remote terminal)、接入终端设备(access terminal)、用户终端设备(user terminal)、用户代理(user agent)、用户装置(user device),本公开实施例中并不限定。
本公开实施例涉及的网络设备,也称为基站,可以包括多个为终端提供服务的小区。根据具体应用场合不同,网络设备又可以称为接入点,或者可以是接入网中在空中接口上通过一个或多个扇区与无线终端设备通信的设备,或者其他名称。网络设备可用于将收到的空中帧与网际协议(Internet Protocol,IP)分组进行相互更换,作为无线终端设备与接入网的其余部分之间的路由器,其中接入网的其余部分可包括网际协议(IP)通信网络。网络设备还可协调对空中接口的属性管理。例如,本公开实施例涉及的网络设备可以是全球移动通信系统(Global System for Mobile communications,GSM)或码分多址接入(Code Division Multiple Access,CDMA)中的网络设备(Base Transceiver Station,BTS),也可以是带宽码分多址接入(Wide-band Code Division Multiple Access,WCDMA)中的网络设备(NodeB),还可以是长期演进(long term evolution,LTE)系统中的演进型网络设备(evolutional Node B,eNB或e-NodeB)、5G网络架构(next generation system)中的5G基站(gNB),也可以是家庭演进基站(Home evolved Node B,HeNB)、中继节点(relay node)、家庭基站(femto)、微微基站(pico)等,本公开实施例中并不限定。在一些网络结构中,网络设备可以包括集中单元(centralized unit,CU)节点和分布单元(distributed unit,DU)节点,集中单元和分布单元也可以地理上分开布置。

本公开实施例中,UE接收到网络设备发送的第一指示信息后,可以根据第一指示信息确定多个时隙上发送数据时所采用的DMRS图样。
为了保证上行信道的覆盖性能,5G Rel-17版本将对上行传输进行增强,主要包括在多个时隙上传输一个TB(Transport Block,传输块),利用多个相邻时隙上的DMRS进行信道估计等。众所周知,DMRS的密度(具体体现为时域上所占的符号以及频域上所占的RE个数)将直接影响信道的传输性能,具体的,更高的DMRS传输密度可以带来更精确的信道估计,但同时会推高数据的码率。基于此,最终的传输性能是信道估计和编码增益的折中。
在本公开实施例中,在终端在多个时隙上传输上行数据的情况下,可采用多种DMRS图样传输DMRS,DMRS图样在连续的多个时隙中进行定义,并具有不同的时频域DMRS密度,例如DMRS图样A,B,C,D等等。本公开中对于具体的DMRS图样不做任何限定,对于DMRS图样的确定方式 亦不做任何限定。例如,DMRS图样可以通过显式信令进行配置,DMRS图样还可以通过协议预定义的方式进行确定,等等。
为了更好的理解多时隙DMRS图样的概念,下面结合图2进行示例性说明。图2仅作为说明以便于理解,并不排除任何其他的DMRS图样定义方法。

作为另一种可能的实现方式,UE可以根据与网络设备约定好的行为隐式的确定在连续多个时隙上发送上行数据时所采用的DMRS图样,为此,本公开实施例提出了另一种DMRS图样的指示方法。
图12为本公开实施例十一提供的DMRS图样的指示方法的流程示意图。
如图12所示,该DMRS图样的指示方法,可以包括以下步骤:
步骤1101,获取UE的传输参数。
其中,传输参数可以为时域传输持续时间。
步骤1102,根据传输参数确定多个时隙上发送数据时所采用的多时隙DMRS图样。
本公开实施例中,UE可以获取与网络设备传输数据时的传输参数,以根据传输参数确定多个时隙上发送数据时所采用的多时隙DMRS图样。
在一种可能的情况下,传输参数可以为时域传输持续时间,这种情况下,可以根据UE所占据的连续时隙个数确定多个时隙上发送数据时所采用的多时隙DMRS图样。下面结合图13进行详细介绍, 图13为本公开实施例十二提供的DMRS图样的指示方法的流程示意图。
如图13所示,该DMRS图样的指示方法,可以包括以下步骤:
步骤1201,获取时域传输持续时间。
其中,时域传输持续时间,为UE传输上行数据所占据的连续时隙个数。上行数据传输所占据的不同连续时隙个数对应不同的DMRS图样,DMRS图样与时隙个数的对应关系由协议预定义的方式确定。
步骤1202,根据UE所占据的连续时隙个数确定多个时隙上发送数据时所采用的多时隙DMRS图样。
本公开实施例中,确定UE传输上行数据所占据的连续时隙个数后,可以根据UE所占据的连续时隙个数确定多个时隙上发送数据时所采用的多时隙DMRS图样。
在本公开实施例中,在上行传输可占用的连续时隙数目为{1,2,4,8}的情况下,当然此情况仅是作为例子支持该方案的实施,并不排除其他连续传输时隙个数。对应的,不同的传输时隙个数对应不同的DMRS图样,例如分别有{multi-slot DMRS pattern#1,multi-slot DMRS pattern#2,multi-slot DMRS pattern#3,multi-slot DMRS pattern#4}与之对应。本公开对于multi-slot DMRS pattern的定义与上行传输所占时隙个数之间的映射关系不做任何限定,例如可通过协议预定义的方式确定,亦可通过其他方式确定。
网络设备和UE根据上行传输在时域上占用的连续时隙个数,分别指示和确定对应的多时隙DMRS图样。对应的,UE侧按照多时隙DMRS图样发送上行DMRS,网络设备侧则根据多时隙DMRS图样接收DMRS并以此进行信道估计和解调。
在一种可能的情况下,在UE所占据的连续时隙个数小于或等于预设阈值的情况下,按照UE所占据的连续时隙个数确定发送数据时所采用的多时隙DMRS图样。
其中,预设阈值,是预先设定的上行传输门限,即上行连续传输所占的时隙个数值。
在另一种可能的情况下,在UE所占据的连续时隙个数大于预设阈值的情况下,按照预设阈值确定发送数据时所采用的多时隙DMRS图样。
作为一个具体的例子,在预设阈值为4的情况下,当上行传输占据的连续时隙个小于等于4个连续时隙时,则按照当前传输所占用的连续时隙个数确定发送数据时所采用的多时隙DMRS图样。当上行传输占据的连续时隙个数大于4,例如连续时隙个数为8,则仍然按照预设阈值为4对应的多时隙DMRS图样传输DMRS。
本公开实施例的DMRS图样的指示方法,获取时域传输持续时间后,根据UE所占据的连续时隙个数确定多个时隙上发送数据时所采用的多时隙DMRS图样。由此,有效地提升了上行信道的传输性能,增加了覆盖范围。
作为另一种可能的实现方式,还可以根据相关调度或指示信息,确定多个时隙上发送数据时所采用的多时隙DMRS图样。下面结合图14进行详细介绍,图14为本公开实施例十三提供的DMRS图样的指示方法的流程示意图。
如图14所示,该DMRS图样的指示方法,可以包括以下步骤:
步骤1301,获取UE的传输参数。
步骤1302,根据调度上行数据信道传输的UL grant中携带的调制与编码策略MCS索引,确定MCS索引对应的DMRS图样。
步骤1303,将MCS索引对应的DMRS图样作为多个时隙上发送数据时所采用的多时隙DMRS图样。
本公开实施例中,可以至少根据MCS隐式地确定多时隙传输所采用的DMRS图样。
在一种可能的情况下,对于PUSCH,可以通过以下标识之中的一个或多个确定是否采用多时隙DMRS图样:多时隙DMRS开启标识;重复传输开启标识;多时隙TB处理开启标识。
在另一种可能的情况下,对于PUCCH,可以通过以下之中的一个或多个确定在多个时隙上发送上行控制信道PUCCH时所采用的多时隙DMRS图样:DCI中携带的PRI;码率与重复传输信息的结合。
