Description

背景技术
解调参考信号(De Modulation Reference Signal，DMRS)是一种可以用在上行传输和下行传输中的参考信号。在终端与网络设备的之间进行的上行传输中，DRMS通常与物理上行共享信道(Physical Uplink Shared Channel，PUSCH)和物理上行控制信道(Physical Uplink Control Channel，PUCCH)的发送相关联，用于对上行信道进行估计，以及网络设备的相干检测和解调。在终端与网络设备之间进行的下行传输中，DMRS又称为用户设备专用的参考信号(User Equipment specific Reference Signal，UE-specific RS)，用于数据的解调。
然而，在现有的通信系统中，无论是在上行传输中还是在下行传输中，传输上述DMRS使用的传输资源的位置是固定的。例如，在上行传输中，用于传输DMRS的传输资源设置在一个时隙的中间。上述这种以固定的传输资源传输DMRS的方式，不够灵活。

具体实施方式
下面将结合附图，对本申请中的技术方案进行描述。
图1是本申请实施例应用的无线通信系统100。该无线通信系统100可以包括网络设备110。网络设备110可以是与终端设备通信的设备。网络设备100可以为特定的地理区域提供通信覆盖，并且可以与位于该覆盖区域内的终端设备进行通信。
图1示例性地示出了一个网络设备和两个终端，可选地，该无线通信系统100可以包括多个网络设备并且每个网络设备的覆盖范围内可以包括其它数量的终端，本申请实施例对此不做限定。
可选地，该无线通信系统100还可以包括网络控制器、移动管理实体等其他网络实体，本申请实施例对此不作限定。
应理解，本申请的技术方案可以应用于各种通信系统，例如：全球移动通讯(Global System of Mobile communication，GSM)系统、码分多址(Code Division Multiple Access，CDMA)系统、宽带码分多址(Wideband Code Division Multiple Access，WCDMA)系统、通用分组无线业务(General Packet Radio Service，GPRS)、长期演进(Long Term Evolution，LTE)系统、先进的长期演进(Advanced long term evolution，LTE-A)系统、通用移动通信系统(Universal Mobile Telecommunication System，UMTS)、新空口(New Radio Access Technology，NR)、5G等。
还应理解，在本申请实施例中，终端设备可以包括但不限于移动台(Mobile Station，MS)、移动终端(Mobile Terminal)、移动电话(Mobile Telephone)、用户设备(User Equipment，UE)、手机(handset)及便携设备(portable equipment)等，该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进行通信，例如，终端设备可以是移动电话(或称为“蜂窝”电话)、具有无线通信功能的计算机等，终端设备还可以是便携式、袖珍式、手持式、计算机内置的或者车载的移动装置。
本申请实施例中，网络设备可以是接入网设备，例如可以是基站、发射和接收点(Transmit and Receive Point，TRP)或接入点，基站可以是GSM 或CDMA中的基站(Base Transceiver Station，BTS)，也可以是WCDMA中的基站(NodeB)，还可以是LTE中的演进型基站(evolved Node B，eNB或e-NodeB)，还可以是NR或5G的基站(gNB)，本申请实施例对此不作具体限定。
现有的通信系统中，DMRS是在固定的传输资源上传输的，对于高速移动性的终端来说，不仅限制了传输DMRS的灵活性，同时无法提高信道估计结果的准确率。对于高速移动的终端来说，随着终端的移动速度的增加，信道变化的速度也在增加，如果仍然使用上述在固定的传输资源上传输DMRS的方式对信道进行实时估计，会使得信道的估计结果误差较大，降低信道估计的准确率。
为了解决现有的通信系统中传输DMRS时的上述问题，在未来通信系统中(例如，5G通信系统)，可以在现有的通信系统中DMRS的传输方式的基础上，继续传输可选的参考信号，以提高信道估计的准确率。
因此，在未来的通信系统中，DMRS的传输方式大体上可以分为两种：
传输方式一：只传输第一类DMRS。通常第一类DMRS可以在普通场景下(例如，位于室内的终端，或者城市公路上移动的终端)，对信道进行有效的估计。在传输第一类DMRS时，可以按照现有的通信系统中传输DMRS的方式，即在一个时域传输单元(例如，一个时隙)的中间的OFDM符号的传输资源上传输DMRS；还可以在一个时域传输单元(例如，一个时隙)中的位于前部的OFDM符号中(例如，一个时隙中的第一个OFDM符号上)传输DMRS。
传输方式二：传输第一类DMRS和可选的参考信号。为了提高高速移动的终端的场景下信道估计的准确率，在传输第一类DMRS的基础上，同时传输可选的参考信号(即，可选地参考信号)，通过增加在一个时域传输单元内发送参考信号的密度，提高信道估计的准确率。例如，传输第一类DMRS所使用的传输资源可以位于一个时域传输单元(例如，一个时隙)中的第一个OFDM符号，则传输上述可选的参考信号的传输资源可以位于该时域传输单元内的第二个OFDM符号。
需要说明的是，上述可选的参考信号还可以称为额外的参考信号(Additional Reference Signal，Additional RS)。本申请实施例对此不作具体限定。
下文结合图2详细描述本申请实施例的参考信号的传输方法。图2是本申请实施例的参考信号的传输方法的示意性流程图，图2所示的方法包括：
210，终端接收网络设备发送的第一信息，所述第一信息用于指示传输待传输的解调参考信号DMRS所使用的传输图样为第一传输图样或第二传输图样。
具体地，上述可选的参考信号可以理解为在终端和网络设备之间被传输的参考信号，也可以不被传输的参考信号。
需要说明的是，上述可选地参考信号可以是DMRS。
需要说明的是，上述第一传输图样和第二传输图样可以是相互独立的传输图样，第一传输图样和第二传输图样分别应用于不同的场合，例如第一传输图样可以应用于上文中传输方式二的应用场合，例如，高移动性的终端和网络设备之间传输DMRS，也就是说，进行信道估计的难度较大的场合；第二传输图样可以应用于上文中传输方式一的应用场合，例如，位于室内的终端，或者城市公路上移动的终端，也就是说，进行信道估计的难度较小的场合。
可选的，所述第一传输图样用于指示所述待传输的DMRS中包含可选的参考信号，所述第二传输图样用于指示所述待传输的DMRS中不包含所述可选的参考信号。
具体地，上述第一传输图样可以是在第二传输图样的基础上，添加用于传输可选的参考信号的传输资源的传输图样，也就是说，第一传输图样可以是在第二传输图样的基础上附加了用于传输可选的参考信号的传输资源。
通过不同的传输图样(第一传输图样和第二传输图样)指示是否传输可选的参考信号，为传输DMRS配置不同的传输方式，以保持提高信道估计的准确性和节省传输DMRS的开销之间的平衡。
可选地，所述第一传输图样指示的传输单元内传输所述待传输的DMRS的所使用的传输资源的数量大于所述第二传输图样指示的传输单元内传输所述待传输的DMRS的所使用的传输资源的数量，可替换的，第一传输图样指示的传输单元内传输所述待传输的DMRS的所使用的传输资源的密度大于所述第二传输图样指示的传输单元内传输所述待传输的DMRS的所使用的传输资源的密度。
可选地，网络设备可以根据终端的通信状态信息确定传输待传输的 DMRS的传输图样为第一传输图样或第二传输图样，也就是说，网络设备可以根据终端的通信状态信息确定待传输的DMRS是否包含可选的参考信号。
可选地，上述通信状态信息可以是影响终端和网络设备之间通信质量的信息，例如，可以是终端的移动速度，终端的位置信息等。
220，所述终端在所述第一传输图样或所述第二传输图样指示的传输资源上与所述网络设备进行所述待传输的DMRS的传输。
具体地，步骤220可以包括：终端在第一传输图样或第二传输图样指示的传输资源上向网络设备发送待传输的DMRS，也就是说，待传输的DMRS是用于上行传输中的参考信号。
步骤220还可以包括：终端在第一传输图样或第二传输图样指示的传输资源上接收网络设备发送的待传输的DMRS，也就是说，待传输的DMRS是用于下行传输中的参考信号。
通过第一信息指示传输待传输的DMRS的传输图样，避免了现有技术中只能在固定的资源上传输DMRS，有利于提高传输DMRS的灵活性。
可选地，作为一个实施例，所述终端接收网络设备发送的第一信息，包括：所述终端接收所述网络设备发送的所述第一信息，所述第一信息中的第一字段用于指示传输所述待传输的DMRS所使用的传输图样为所述第一传输图样或所述第二传输图样。
具体地，第一信息可以通过第一字段的取值指示传输待传输的DMRS所使用的传输图样为第一传输图样或者第二传输图样。
例如，第一字段为1比特(bit)，当第一字段的取值为1时，可以用于指示传输待传输的DMRS所使用的传输图样为第一传输图样，当第一字段的取值为0时，可以用于指示传输待传输的DMRS所使用的传输图样为第二传输图样。
又例如，第一字段为1bit，当第一字段的取值为0时，可以用于指示传输待传输的DMRS所使用的传输图样为第一传输图样，当第一字段的取值为1时，可以用于指示传输待传输的DMRS所使用的传输图样为第二传输图样。
可选地，作为一个实施例，所述终端接收网络设备发送的第一信息，包括：所述终端接收所述网络设备发送的所述第一信息，所述第一信息通过是否携带第二字段指示传输所述待传输的DMRS所使用的传输图样为所述第 一传输图样或所述第二传输图样。
