本申请涉及通信技术领域，尤其涉及一种参考信号图案的确定方法及装置。

现有NR标准协议中，解调参考信号(Demodulation reference signal，DMRS)包括类型1和类型2两类，网络设备通过无线资源控制(Radio Resource Control，RRC)配置选用类型1还是类型2。在频域层面，类型1的每个DMRS端口在一个资源块(Resource Block，RB)内占了6个资源元素(Resource Element，RE)，类型2的每个DMRS端口在一个RB内占了4个RE。在时域层面，每个调度单元均配置有DMRS配置；其中每个调度单元依赖于网络配置，可由有前置DMRS，或者前置DMRS和额外DMRS构成。

具体实施方式
下面结合本申请实施例中的附图对本申请实施例进行描述。
应理解，本申请实施例的技术方案可以应用于全球移动通信***(Global System for Mobile Communication，CSM)、码分多址(Code Division Multiple Access，CDMA)***、宽带码分多址(Wideband Code Division Multiple access，WCDMA)***、全球微波互联接入(Worldwide Interoperability for Microwave Access，Wi-MAX)***、长期演进(Long Term Evolution，LTE)***、5G通信***(例如新空口(New Radio，NR))、多种通信技术融合的通信***(例如LTE技术和NR技术融合的通信***)、或者适用于未来新的各种通信***，例如6G通信***、7G通信***等，本申请实施例对此不作限定。本申请实施例的技术方案也适用于不同的网络架构，包括但不限于中继网络架构、双链接架构、车辆到任何物体的通信(Vehicle-to-Everything)架构等。
本申请实施例涉及终端设备。终端设备包括无线通信功能的设备，该终端设备可以是手机(mobile phone)、平板电脑(pad)、带无线收发功能的电脑、虚拟现实(Virtual Reality，VR)终端设备、增强现实(Augmented Reality，AR)终端设备、工业控制(industrial control)中的无线终端、无人驾驶(self driving)中的无线终端、远程医疗(remote medical)中的无线终端、智能电网(smart grid)中的无线终端、智能家庭(smart home)中的无线终端等。终端设备也可以是具有无线通信功能的手持设备、车载设备、可穿戴设备、计算机设备或连接到无线调制解调器的其他处理设备、未来5G网络中的终端设备或者未来演进的公用陆地移动通信网络(Public Land Mobile Network，简称PLMN)中的终端设备等。在不同的网络中终端设备可以叫做不同的名称，例如：用户设备、接入终端、用户单元、用户站、移动站、移动台(Mobile Station，MS)、远方站、远程终端、移动设备、用户终端、终端、无线通信设备、用户代理或用户装置、蜂窝电话、无绳电话、会话启动协议(Session Initiation Protocol，SIP)电话、无线本地环路(Wireless Local Loop，WLL)站、个人数字处理(Personal Digital Assistant，PDA)、5G网络或未来演进网络中的终端设备等，本申请实施例对此并不限定。
本申请实施例涉及网络设备。网络设备可以是用于与终端设备进行通信的设备，包含无线接入网(Radio Access Network，RAN)的设备，RAN的基站控制器以及核心网侧的设备。例如，网络设备可以是蜂窝网络中接入网侧的RAN的基站，包括但不限于：演进型节点B(evolved Node B，eNB)、无线网络控制器(Radio Network Controller，RNC)、节 点B(Node B，NB)、基站控制器(Base Station Controller，BSC)、基站收发台(Base Transceiver Station,BTS)、家庭基站(例如，Home evolved Node B，或Home Node B，HNB)、基带单元(Base Band Unit，BBU)、管理实体(Mobility Management Entity，MME)；再例如，网络设备也可以是无线局域网(Wireless Local Area Network，WLAN)中的节点设备，例如接入控制器(Access Controller，AC)，网关，或WIFI接入点(Access Point，AP)；再例如，网络设备也可以是NR***中的接入网设备(例如gNB，CU，DU),以及继续演进的节点B(ng-eNB),其中gNB和终端设备之间采用NR技术进行通信，ng-eNB和终端设备之间采用E-UTRA(Evolved Universal Terrestrial Radio Access)技术进行通信，gNB和ng-eNB均可连接到5G核心网。本申请实施例中的网络设备还包含在未来新的通信***中提供基站功能的设备等。

目前业界正在广泛地探讨在终端侧引入人工智能技术，即在终端侧采用智能化模块，通过智能化模块对信道进行估计，减少导频的数量，使得DMRS图案可呈现稀疏特性，进而使得信道估计性能可大大优于现在没有采用智能化模块的信道估计性能，并且有效地降低了资源开销，从而提升网络性能。考虑到不同用户的智能化的能力不同，则其可支持的DMRS图案的稀疏度可能也不同，而对于引入智能化模块后，怎样确定呈现稀疏特性的DMRS图案，目前并无具体地方案。
为了解决上述问题，本申请实施例提出了一种参考信号图案的确定方法，考虑不同终端设备的智能化能力的不同，通过终端设备上传能力信息，使得终端设备在智能化场景下确定的DMRS图案能够满足终端设备支持的DMRS图案的稀疏度，从而有效地降低资源开销，提升网络性能。
为了使本技术领域的人员更好地理解本申请方案，下面将结合本申请实施例中的附图，对本申请实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅是本申请 一部分实施例，而不是全部的实施例。基于本申请中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本申请保护的范围。
参阅图2，图2提供了一种参考信号图案的确定方法，上述方法可以在如图1所示的通信***上执行，所述方法包括如下步骤。
S210、终端设备向网络设备发送能力信息，所述能力信息用于指示所述网络设备配置解调参考信号DMRS配置信息。
在本申请实施例中，考虑到不同终端设备智能化的能力不同，其可支持的DMRS图案的稀疏度也会不同。在接收到网络设备发送的DMRS配置信息之前，终端设备可以将进行能力上报，以使得网络设备可以获知终端设备的智能化能力，也即获知终端设备可以支持的DMRS图案的稀疏度，进而使得网络设备可以基于终端设备的能力进行配置DMRS图案。
在一种可能的实现方式中，所述能力信息包括以下至少一项：DMRS时域密度、DMRS频域密度和DMRS频域移位密度。
在本申请实施例中，由于不同终端设备智能化的能力不同，其可支持的DMRS的时域资源和频域资源也会有所不同。因此在上报的能力信息中携带该终端设备所支持的DMRS的时域资源和频域资源，以使得网络设备配置的DMRS图案能够满足该终端设备的能力。
可选的，所述DMRS时域密度可以表示为任意两个相邻DMRS符号的间隔、任意两个相邻DMRS时隙的间隔或任意两个相邻DMRS调度单元的间隔中的任一种。
具体地，DMRS广泛存在于各个重要的物理信道当中，如下行的广播物理信道(Physical Broadcast Channel，PBCH)、物理下行控制信道(Physical Downlink Control Channe，PDCCH)和物理下行链路共享信道(Physical Downlink Shared Channel，PDSCH)，以及上行的物理上行链路控制信道(Physical Uplink Control Channel，PUCCH)和上行物理共享信道(Physical Uplink Shared Channel，PUSCH)。能力信息中的DMRS时域密度用于指示该终端设备所支持的时域资源。例如，如图3a所示，在时域上，时隙1和时隙2上均包括DMRS，因此能力信息指示终端设备所支持的DMRS时域密度为1个时隙。
应理解，本申请实施例中，符号表示时间单位，本文中的符号也可以称为OFDM符号，本申请实施例并不限于此。
还应理解，本申请实施例中一个资源单元可以包括n个符号，n为大于或等于2的整数，例如，n为7、14或者为2-13中的任意一个数值，本申请实施例并不限于此。
可选的，所述DMRS频域密度为同一DMRS端口在频域上的资源元素RE或资源块 RB的间隔。所述DMRS频域移位粒度为时域上任意两个相邻DMRS符号、任意两个相邻DMRS时隙或任意两个相邻DMRS调度单元中的任一种在同一DMRS端口的频域上的移位粒度。
其中，能力信息中的DMRS频域密度和DMRS频域移位粒度用于指示该终端设备所支持的频域资源。在NR***中，DMRS最大支持12个DMRS端口，根据配置的不同的DMRS类型，每个端口内的任意两个RB或RE内的频域间隔不同。通过所述DMRS频域密度可以获知每个DMRS端口的频域间隔，再根据所述DMRS频域移位粒度，可以得到所述DMRS在每个DMRS端口的频域位置。例如，如图3a所示，在频域上，任意一个DMRS 0/1与下一个DMRS 0/1之间相差4个RE，时域上时隙2中的第一个DMRS 0/1所在频域的位置与时隙1中的第一个DMRS 0/1所在频域的位置的差为2个RE，因此能力信息指示终端设备所支持的DMRS频域密度为4个RE、DMRS频域移位粒度为2个RE。
应理解，本申请实施例中，DMRS图案也可以称为DMRS图样、DMRS分布信息或DMRS属性，该DMRS图案能够表示DMRS占用的时域资源和频域资源，本申请实施例并不限于此。
在另一种可能的实现方式中，所述能力信息包括以下至少一项：最大的DMRS时域密度、最小的DMRS时域密度、最大的DMRS频域密度、最小的DMRS频域密度、最大的DMRS频域移位密度和最小的DMRS频域移位密度。
在具体实现中，终端设备可以将其支持的最大或最小的时域资源，以及最大或最小的频域资源，根据终端设备所支持的最大或最小的DMRS时频资源，网络设备配置能够满足该终端设备的能力的DMRS图案。
S220、网络设备接收来自终端设备的能力信息，并根据所述能力信息配置DMRS配置信息，所述DMRS配置信息用于所述终端设备确定DMRS图案。
可选的，所述DMRS配置信息包括以下至少一项：参考DMRS图案，所述DMRS时域密度、所述DMRS频域密度和所述DMRS频域移位粒度。
具体地，网络设备可以根据终端设备上报的其所支持的DMRS时频资源，或者其所支持的最大或最小的DMRS时频资源，为该终端设备配置满足其能力的参考DMRS图案，例如，若能力信息中的最大DMRS时域密度为1个时隙、最大DMRS频域密度为4个RE，则网络设备配置的参考DMRS图案可以如图3b所示。
示例性地，网络设备接收到终端设备上报的其所支持的DMRS时频资源，或者其所支 持的最大或最小的DMRS时频资源后，也可以直接配置满足该终端设备能力的时频资源，例如，若能力信息中的DMRS时域密度为3个时隙、DMRS频域密度为6个RE、DMRS频域移位粒度为2，网络设备可以配置该终端设备的DMRS时域密度为1个时隙、DMRS频域密度为4个RE、DMRS频域移位粒度为1个RE。
S230、网络设备向所述终端设备发送所述DMRS配置信息。
在本申请实施例中，网络设备可以通过预设的方式将配置的DMRS配置信息发送给终端设备。其中，网络设备可以通过高层信令、MAC层指令、下行控制信息或***信息等发送所述DMRS配置信息。
可选的，所述DMRS配置信息承载于无线资源控制RRC消息、多媒体接入控制MAC消息和下行链路控制信息DCI消息中的至少一种。
具体地，网络设备向终端设备发送RRC消息、MAC消息和/或DCI消息，该消息中携带有DMRS配置信息，该配置信息用于配置或指示终端设备采用的DMRS图案。所述RRC消息可以包括但不限于RRC Release消息、RRC connection reconfiguration消息、RRC connection reestablishment消息、RRC connection setup消息、RRC connection resume消息或其他RRC消息中的任意一种；所述MAC消息可以是MAC控制单元(MAC Control Element，MAC CE)。
示例性地，DMRS配置信息还可以承载于***信息(例如，网络设备广播的***信息块)或新增的控制消息中。
S240、终端设备接收来自所述网络设备的所述DMRS配置信息，并根据所述DMRS配置信息确定DMRS图案。
在本申请实施例中，终端设备接收网络设备配置的DMRS配置信息后，根据参考DMRS图案、DMRS时域密度、DMRS频域密度和DMRS频域移位粒度，以及终端设备的资源调度情况，确定其使用的DMRS图案。例如，网络设备通过RRC消息配置参考DMRS图案，一个参考DMRS图案示意如图3b所示，网络设备通过RRC消息指示DMRS时域密度为1个时隙，一个RB内的DMRS频域密度为4个RE，DMRS频域移位粒度为2个RE，若终端设备被调度的PDSCH或者PUSCH占用了两个时隙，终端设备可确定DMRS图案如图3a所示。
又一举例说明，网络设备通过DCI消息配置参考DMRS图案如图3b所示，网络设备通过DCI消息指示DMRS时域密度为2个时隙，一个RB内的DMRS频域密度为4个RE， DMRS频域移位粒度为4个RE。如果终端设备被调度的PDSCH或者PUSCH占用了两个时隙，则可终端设备确定DMRS图案如图3c所示。
可以看出，本申请实施例提出的参考信号图案的确定方法，终端设备向网络设备发送能力信息，网络设备根据该能力信息配置DMRS配置信息并发送，终端设备接收到该DMRS配置信息后，根据该DMRS配置信息确定DMRS图案。在本申请中考虑不同终端设备的智能化能力的不同，通过终端设备上传能力信息，使得终端设备在智能化场景下确定的DMRS图案能够满足终端设备支持的DMRS图案的稀疏度，从而有效地降低资源开销，提升网络性能。
