  • the present invention relates to the field of wireless communications, and more particularly to a method, network device, and terminal device for transmitting a demodulation reference signal DMRS.
  • the receiving end can acquire the wireless channel information and use the estimated wireless channel information to perform data reception and demodulation, the data receiving quality can be greatly improved, and in order to achieve the above purpose, the transmitting end is usually At the same time of transmitting data, some reference signals are transmitted. These reference signals are preset, and both ends of the transmitting and receiving are predicted. By estimating the reference signals, the receiving end can obtain wireless channel information for receiving and demodulating data. In order to improve resource utilization, in actual systems, only a small amount of resources are often used for the transmission of reference signals. The reason why the channel information can be obtained by transmitting the reference signal using only a small part of the resources is because the wireless channel is often block fading, that is, it has correlation in two dimensions of frequency and time. As long as the time interval of the reference signal is less than the coherence time and the interval in the frequency domain is smaller than the coherence bandwidth, channel state information on all time-frequency resources can be obtained according to the reference signals.
  • the reference signal is placed on the first symbol when transmitting data, and after receiving the first symbol, the receiving end can estimate the entire resource block according to the reference signal therein.
  • the channel state information is started, and the received data is detected, so that the receiving side detection is performed in the subsequent data receiving process, thereby shortening the receiving delay.
  • the channel state information estimated from the reference signal transmitted on the foremost symbol, when used for data reception is inferior to the performance on the lower symbol. Therefore, in 5G systems, when high-order modulation is used in some special scenes such as high-speed or high-frequency systems, in addition to using the first symbol to transmit the reference signal, some additional reference signals are transmitted in the subsequent symbols.
  • the reference signal is used together with the reference signal transmitted on the foremost symbol for demodulation reception of the data, which can effectively improve the reception performance of the system.

Description

传输解调参考信号的方法、网络设备和终端设备 技术领域
本发明涉及无线通信领域，并且更具体地，涉及一种传输解调参考信号DMRS的方法、网络设备和终端设备。
背景技术
在无线通信***中，若是接收端能够获取无线信道信息，并利用估计得到的无线信道信息进行数据的接收解调，则能够大大的提高数据接收质量，而要实现上述目的，通常是发射端在发射数据的同时，发射一些参考信号，这些参考信号是预设的，收发两端都是预知的，接收端通过估计这些参考信号，就可以获得无线信道信息，以用于数据的接收解调。为了提高资源利用率，在实际***中，往往只有一小部分资源用于参考信号的发射。而之所以可以只采用一小部分资源发射参考信号就能够获得信道信息，是因为无线信道往往是块衰落的，即在频率和时间两个维度上具有相关性。只要保证参考信号在时间上的间隔小于相干时间，且在频域上的间隔小于相干带宽，就能根据这些参考信号得到所有时频资源上的信道状态信息。
为了降低***通信的时延，5G***中，在传输数据时将参考信号放置在最开始的符号上，接收端在接收到第一个符号后，就可以根据其中的参考信号估计出整个资源块的信道状态信息，并开始对接收的数据进行检测，从而在后续的数据接收过程中，实现边接收边检测，从而缩短接收时延。但根据最前面符号上传输的参考信号估计得到的信道状态信息，在用于数据接收时，对于越靠后的符号上的性能越差。因此5G***中，在一些特殊场景例如高速或者高频***中采用高阶调制时，除了使用最前面的符号传输参考信号外，在后续的符号中也会传输一些附加的参考信号，这些附加的参考信号与最前面符号上传输的参考信号共同用于数据的解调接收，这样能够有效提高***的接收性能。为了应对不同的场景，例如图2所示，这些用于传输参考信号的符号会有不同的分布样式。
上述基于参考信号进行信道估计并进行数据解调的***中，参考信号的接收信噪比的高低将直接影响信道估计的效果。在这种参考信号的传输资源 可以灵活配置的多端口***中，为了提高参考信号接收信噪比，需要避免其他端口的数据传输对当前端口上传输的参考信号带来的干扰。一种有效的方法是其他端口在当前端口传输参考信号的资源上不传输数据，即保持静默。
因此，如何实现通过数据静默来提高参考信号接收信噪比是急需解决的问题。
发明内容
本发明实施例提供一种传输解调参考信号DMRS的方法、网络设备和终端设备，能够提高DMRS的接收信噪比。
第一方面，提供了一种传输DMRS的方法，该方法包括：
网络设备确定第一端口对应的DMRS样式，和所述第一端口对应的静默样式，所述第一端口为所述网络设备用于与终端设备进行DMRS传输的端口；
所述网络设备通过所述第一端口，在所述DMRS样式指示的资源上映射所述终端设备的DMRS，且在所述静默样式指示的资源上不映射数据；或者所述网络设备通过所述第一端口，在所述DMRS样式指示的资源上接收来自所述终端设备的DMRS，且在所述静默样式指示的资源上假设数据功率为零。
因此，网络设备除了为终端设备配置传输DMRS的DMRS样式，还为终端设备配置了静默样式，使得其他终端设备在该静默样式指示的资源上传输DMRS时，不会受到该终端设备的数据传输的干扰，并且该终端设备在传输DMRS时，也不会受到替他终端设备数据传输的干扰，从而能够提高DMRS的接收信噪比。
可选地，网络设备和终端设备在确定了DMRS样式和静默样式后，可以根据第一端口的端口号，以及
Figure PCTCN2016100487-appb-000001
来确定DMRS样式指示的资源以及静默样式指示的资源，其中，m＝0,1,...3NRB-1，NRB是以资源块为单位的带宽，这些带宽被用于为终端设备提供数据服务，
Figure PCTCN2016100487-appb-000002
其中
Figure PCTCN2016100487-appb-000003
表示每个资源块包含的子载波数，不同端口vshift取值不同，例如端口1，vshift为1；端口2，vshift为2；端口3，vshift为3。
应理解，上述方法是以频分的方式实现不同端口DMRS的复用，也可 以采用码分或者时分，上述方法只是为了举例说明本发明的可实现性，并不限定本发明的保护范围。
第一端口对应的DMRS样式与除所述第一端口外的其他端口对应的DMRS样式可以相同或者不同。如果所述第一端口对应的DMRS样式与除所述第一端口外的其他端口对应的DMRS样式相同，那么网络设备可以采用隐式配置的方式向终端设备指示静默样式和DMRS样式。
以下行传输为例，该静默样式可以通过隐式配置的方式来实现，即网络设备在对终端设备进行调度时，不同端口上采用相同的DMRS样式，在其他端口传输DMRS的资源上，该终端设备不传输数据。该终端设备默认其他端口上的DMRS样式，与第一端口的DMRS样式相同，并且假设其他端口传输DMRS的资源上的信号功率为零。
可选地，在第一方面的一种实现方式中，所述方法还包括：所述网络设备向所述终端设备发送第一资源指示信息，所述第一资源指示信息用于指示所述DMRS样式和所述静默样式。
该静默样式也可以通过显式配置的方式来实现，即在网络设备的调度信令中同时包括第一资源指示信息，该第一资源指示信息用于指示当前终端设备所使用的DMRS样式和静默样式。以下行传输为例，终端设备接收到调度信令后，根据该静默样式确定需要静默的资源的位置，并假设该静默样式所指示的资源上的信号功率为零。
可选地，在第一方面的一种实现方式中，所述方法还包括：所述网络设备向所述终端设备发送第一样式标识，所述第一样式标识用于指示所述网络设备的多个端口中的每个端口对应的DMRS样式。
可选地，在第一方面的一种实现方式中，所述网络设备向所述终端设备发送所述第一样式标识之前，所述方法还包括：
所述网络设备确定多个DMRS样式，所述多个DMRS样式包括所述DMRS样式；所述网络设备向所述终端设备发送所述多个DMRS样式的信息。
该静默样式还可以通过半静态配置的方式来实现，即在网络设备的调度信令中同时包括第一样式标识，该第一样式标识用于指示网络设备的每个端口对应的DMRS样式，在所述网络设备向所述终端设备发送样式标识之前，网络设备可以通过高层信令向终端设备发送预设的多个DMRS样式，并通 过下行调度信令动态通知终端设备该样式标识。终端设备获得该样式标识后，就能够在获得的多个DMRS样式中，确定当前每个端口对应的DMRS样式，从而确定第一端口对应的静默样式所指示的资源的位置，并假设在相应的静默资源单元上的信号功率为零。
可选地，在第一方面的一种实现方式中，所述方法还包括：所述网络设备向所述终端设备发送用于指示所述DMRS样式的第二资源指示信息；所述网络设备向所述终端设备发送用于指示所述第一端口对应的静默样式的第二样式标识。
可选地，在第一方面的一种实现方式中，在所述网络设备向所述终端设备发送第二样式标识之前，所述方法还包括：所述网络设备确定多个静默样式，所述多个静默样式包括所述静默样式；所述网络设备向所述终端设备发送所述多个静默样式的信息。
基于上面的描述，对于静默样式的配置方式可以是显式的、半静态的；或者显式的、动态的；或者隐式的、静态的。其中，隐式静态的配置方法虽然不需要增加额外的配置开销，但是会对调度造成很大的限制，影响***性能和客户体验；显式动态的配置方式最为灵活，但是需要大量宝贵的物理层资源用于传输配置信息。显式半静态兼顾了灵活和开销两方面，因而显式半静态的配置方式是较为优选的。
第二方面，提供了一种传输DMRS的方法，该方法包括：
终端设备获取第一端口对应的DMRS样式，和所述第一端口对应的静默样式，所述第一端口为网络设备用于与所述终端设备进行DMRS传输的端口；
所述终端设备通过所述第一端口，在所述DMRS样式指示的资源上映射所述终端设备的DMRS，且在所述静默样式指示的资源上不映射数据；或者所述终端设备通过所述第一端口，在所述DMRS样式指示的资源上获取所述终端设备的DMRS，且在所述静默样式指示的资源上假设数据功率为零。
因此，终端设备除了能够获取传输DMRS的DMRS样式，还能够获取静默样式，使得其他终端设备在该静默样式指示的资源上传输DMRS时，不会受到该终端设备的数据传输的干扰，并且该终端设备在传输DMRS时，也不会受到替他终端设备数据传输的干扰，从而能够提高DMRS的接收信噪比。
可选地，在第二方面的一种实现方式中，所述终端设备确定第一端口对应的DMRS样式，和所述第一端口对应的静默样式，包括：

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，都属于本发明保护的范围。
应理解，本发明实施例的技术方案可以应用于各种通信***，例如：全球移动通讯(Global System of Mobile communication，简称“GSM”)***、码分多址(Code Division Multiple Access，简称“CDMA”)***、宽带码分 多址(Wideband Code Division Multiple Access，简称“WCDMA”)***、通用分组无线业务(General Packet Radio Service，简称“GPRS”)、长期演进(Long Term Evolution，简称“LTE”)***、通用移动通信***(Universal Mobile Telecommunication System，简称“UMTS”)、等目前的通信***，以及，尤其应用于未来的5G***。
本发明实施例中的终端设备也可以指用户设备(User Equipment，简称“UE”)、接入终端、用户单元、用户站、移动站、移动台、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。接入终端可以是蜂窝电话、无绳电话、会话启动协议(Session Initiation Protocol，简称“SIP”)电话、无线本地环路(Wireless Local Loop，简称“WLL”)站、个人数字处理(Personal Digital Assistant，简称“PDA”)、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。
本发明实施例中的网络设备可以是用于与终端设备通信的设备，该网络设备可以是GSM或CDMA中的基站(Base Transceiver Station，简称“”BTS)，也可以是WCDMA***中的基站(NodeB，简称“NB”)，还可以是LTE***中的演进型基站(Evolutional NodeB，简称“eNB或eNodeB”)，还可以是云无线接入网络(Cloud Radio Access Network，简称“CRAN”)场景下的无线控制器，或者该网络设备可以为中继站、接入点、车载设备、可穿戴设备以及未来5G通信网络中的网络设备或者未来演进的PLMN网络中的网络设备等。
图1是本发明实施例的一种应用场景的示意性架构图。如图1所示的通信***的基本网络架构可以包括网络设备例如eNodeB 10，以及至少一个终端设备例如用户设备(User Equipment，简称“UE”)20和UE 30。如图3所示，eNodeB 10用于为UE 20和UE 30提供通信服务，并接入核心网，UE20和UE 30通过搜索eNodeB 10发送的同步信号、广播信号等而接入网络，从而进行与网络的通信。其中，该通信***中的至少一个终端设备在与网络设备进行参考信号的传输时，不同终端设备用于传输参考信号的符号的位置可以不相同。
本发明实施例中的网络可以是指公共陆地移动网络(Public Land Mobile Network，简称“PLMN”)或者设备对设备(Device to Device，简称“D2D”)网络或者机器对机器/人(Machine to Machine/Man，简称“M2M”)网络或者其他网络，图1只是本发明实施例的一个应用场景的示例，本发明实施例还可以应用于其他场景，另外，图1只是举例的简化示意图，网络中还可以包括其他网络设备，图1中未予以画出。
下面以eNodeB 10、UE 20和UE 30为例，并以基于正交频分复用(Orthogonal Frequency Division Multiplexing，简称“OFDM”)的长期演进***(Long Term Evolution，简称“LTE”)为例。如图2所示的用于传输参考信号的资源的示意图，一个子帧中的前面的至多3个OFDM符号上用于控制信道的传输，其接收和解调是基于公共参考信号(Common reference signal，简称“CRS”)，用于数据信道解调的上行参考信号例如解调参考信号(Demodulation reference signal，简称“DMRS”)的传输资源如图2中的阴影部分，图2中的每个小方块代表最小的资源单位，被称为资源单元，在时间上是一个OFDM符号的时长，在频率上是一个子载波的宽度。利用信道的频率相关性，接收可以端利用位于同一个OFDM符号上的参考信号估计得到信道状态信息，并可以通过插值获取同一个OFDM符号上其他资源单元上的信道状态信息；利用信道的时间相关性，接收端利用位于不同OFDM符号上的参考信号得到的信道状态信息，并通过插值获得不同OFDM符号上资源单元上的信道状态信息。
在5G***中，为了降低***通信的时延，可以将参考信号放置在最开始的OFDM符号上，例如图3所示的用于传输参考信号的资源的示意图。图3中示出的资源用于数据信道的发送，控制信道的发送所使用的资源应该在数据信道之前，这里均没有画出。另外，图3仅仅作为示意，图3中示出的传输参考信号的在频域上的密度在实际***中可以不同。
对于这种参考信号资源的分布方式，接收端在收到第一个OFDM符号上的参考信号后，就能估计出整个资源块的信道状态信息，并开始对接收数据进行检测，从而在后续的数据接收过程中，实现边接收边检测，从而缩短接收时延。但是由于只有最前面的OFDM符号用于参考信号的传输，后面的OFDM符号上的信道状态信息只能基于这些在最前面OFDM符号上获得的信道状态信息获得，这种方式对于大部分场景下的数据接收是没有问题 的。但是位于后面的OFDM符号上的信道状态与处于最前面的OFDM符号上的信道状态之间的相关度，明显低于中间OFDM上的信道状态与处于最前面OFDM符号上的信道状态的相关度，这意味着，根据最前面OFDM符号上估计得到的信道状态信息进行数据解调时，越靠后的OFDM符号上的性能越差，尤其是在高速场景下，相干时间大大缩短，这时候这种前置参考信号样式，会严重影响***接收性能。另外，在高频***中，由于晶振的非理想性，会引起相位噪声，相位噪声对于接收性能会有影响，尤其是当采用高阶调制时，相位噪声需要估计和补偿，否则将会导致性能下降。更为严重的是，相位噪声是快速变化的，每个OFDM符号都是变化的，这时候，若是在最前面的符号上传输参考信号，并根据参考信号估计得到的信道状态和相位噪声来对后续的OFDM符号上的数据做解调，会造成***性能的极大下降。
为了解决上述问题，在5G***中，除了使用最前面的符号来传输参考信号之外，还将在后续的OFDM符号中***一些附加的解调参考信号，在大部分场景下，最前面符号上的解调参考信号将单独用于数据解调，附加参考信号将不被发送；而在一些特殊场景下，例如高速场景下、或者高频***中采用高阶调制时，在时域上具有一定密度的附加参考信号将被发送，这时候，前面符号上的解调参考信号和紧随其后的附加的解调参考信号共同用于数据的解调接收。
为了应对不同的场景，传输参考信号的OFDM符号会具有不同的分布样式，图4给出了一些不同的分布样式，例如图4示出的样式1可以用于高频***中相位噪声的估计，而样式2至样式4，可以用于不同速度的移动场景下的数据解调，而样式5可以认为是缺省配置，能够用于大部分常见场景下的数据解调。
进一步地，信道估计的性能是由参考信号的接收信噪比决定，为了避免参考信号被干扰，最为常见的方法是：在正交的时频资源上使用不同端口传输参考信号。图5所示的用于传输参考信号的资源的示意图，例如对于两端口的***，在端口1传输参考信号的时频资源上，端口2上会保持静默，即不传输任何数据，同样在端口2传输参考信号的时频资源上，端口1上也保持静默。
例如，eNodeB 10的端口1在传输参考信号时，其端口2需要在端口1 传输参考信号的符号上不发送任何数据，那么则需要在为参考信号配置传输资源的同时，使端口2对应的终端设备能够获知需要保持静默的资源的样式。如图5所示，若是端口1用于UE 20的数据收发，端口2用于UE 30的数据收发，同时eNodeB 10为UE 20和UE 30确定了用于传输参考信号的资源的样式，这时UE 20和UE 30除了需要知道各自的用于发送参考信号的资源的样式，还需要知道各自对应的端口上哪些资源上需要保持静默，这样才能够避免当其他终端设备在这些静默资源上发送数据时，对其他终端设备的参考信号的接收信噪比造成影响。
又例如，eNodeB 10在端口1向UE 20传输参考信号时，端口2在端口1传输参考信号的资源上不发送任何数据，这时，为了避免端口2对应的终端设备在没有发射数据的资源上尝试接收数据所造成的***性能下降，则需要在为参考信号配置传输资源的同时，使端口2对应的终端设备能够获知静默样式。如图5所示，若是端口1用于UE 20的数据收发，端口2用于UE 30的数据收发，同时eNodeB 10为UE 20和UE 30确定了用于传输参考信号的资源的分布样式，这时UE 20和UE 30除了需要知道各自的用于传输参考信号的资源的样式，还需要知道各自对应的端口上的静默样式，在该静默样式指示的静默资源上没有自己所需的数据传输，这样才能够避免在UE 20和UE 30自己所对应端口的静默资源上收到其他端口的数据，提高数据收发性能，例如UE 20需要避免接收端口1的静默资源上的数据，否则会收到用于UE 30的收发的参考信号，从而影响UE 20数据的收发性能。。
如图5中所示，UE 20的DMRS样式为UE 30的静默样式，UE 30的DMRS样式为UE 20的静默样式。
本发明实施例中，网络设备在为终端设备配置用于传输参考信号的资源时，终端设备还能够获取需要保持静默的资源位置，从而在网络设备通过不同端口发送参考信号时，参考信号不会受到其他数据的干扰，从而能够提高DMRS的接收信噪比。
图6是根据本发明实施例的传输DMRS的方法的流程交互图。图5所示的方法中，解调参考信号的发送端可以为终端设备或网络设备，解调参考信号的接收端可以为终端设备或网络设备。例如，还可以是解调参考信号的发送端为终端设备，解调参考信号的接收端为另一终端设备，此时本申请实施例可以应用D2D传输。另外，发送端和接收端之间的传输，可以通过无 线电波来传输，也可以通过可见光、激光、红外、光纤等传输媒介来传输，本发明实施例对此并不限定。
图6示出了网络设备和终端设备，网络设备例如可以是图1中的eNodeB10，终端设备例如可以是图1中的UE 20或UE 30，但网络设备可以与包括UE 20和UE 30在内的多个终端设备之间利用本发明实施例的方法进行DMRS的传输，其他终端设备所执行的方法可以参考终端设备执行的方法，为了简洁，这里不再赘述。本发明实施例以DMRS为例进行描述，但本发明所述的方法也可以使用与其他参考信号的传输。如图6所示，该传输DMRS的方法包括：
在610中，网络设备确定第一端口对应的DMRS样式，和所述第一端口对应的静默样式。
其中，所述第一端口为所述网络设备用于与终端设备进行DMRS传输的端口。
具体地说，这里的DMRS样式为用于发送或接收DMRS的样式，而该静默样式用于表示在静默样式指示的静默资源上不进行任何数据的发送或接收。网络设备可以通过多个端口与多个终端设备之间同时进行DMRS的传输，网络设备可以为每个端口配置一种DMRS样式(DMRS pattern)，网络设备根据每个端口对应的DMRS样式，在每个端口上向该端口对应的终端设备发送DMRS，或者在每个端口上接收该端口对应的终端设备发送的DMRS。同时，网络设备还为每个端口配置对应的静默样式(muting pattern)，在每个端口的静默资源上不向该端口对应的终端设备发送数据，也不接收该终端设备发送的数据。
应注意，本发明实施例中，在网络设备同时与多个终端设备之间进行DMRS的传输时，对于该多个终端设备中的任意一个终端设备，该终端设备对应的端口上的DMRS样式，也就是该多个终端设备中其他终端设备对应的端口上的静默样式；该终端设备对应的端口上的静默样式，也就是该多个终端设备中的其他终端设备对应的端口上的DMRS样式所组成的集合。
该DMRS样式或静默样式例如可以为图4所示的五种样式，图4中示出的五种样式中，在用于传输数据的数据资源的第一个符号上，用于传输DMRS的资源单元(Resource Element，简称“RE”)在频域上按照一定密度分布；在第一个符号之后的符号上，用于传输DMRS的资源单元在时域上 按照一定的密度分布。例如图4，在样式1，或者称为配置(Configuration)1所指示用于发射DMRS的资源在时域上是连续的，可以用于高频***；而样式2至样式4所指示的用于发射DMRS的资源在时域上的密度逐渐减小，可以用于不同速度的移动场景下；而样式5可以认为是缺省配置，只有在第一个符号上传输DMRS，能够用于大部分常见场景下。
应理解，网络设备的多个端口上可以分别对应不同的DMRS样式，也可以对应相同的DMRS样式，相应的，这多个端口上对应的静默样式也可以不同或者相同。
在620中，终端设备确定第一端口对应的DMRS样式，和所述第一端口对应的静默样式。
具体地说，当不同端口对应不同的DMRS样式和静默样式时，620中终端设备确定的DMRS样式和静默样式，可以是从网络设备获取的，也就是终端设备接收网络设备为其配置的DMRS样式和静默样式；当不同端口对应相同的DMRS样式和静默样式时，终端设备可以无需从网络获取，而是直接使用该默认的DMRS样式进行DMRS传输并在该静默样式指示的静默资源上不传输数据。
本发明实施例中，由于网络设备除了为终端设备配置传输DMRS的DMRS样式，还为终端设备配置了静默样式，使得其他终端设备在该静默样式指示的资源上传输DMRS时不会受到该终端设备的数据传输的干扰，因此能够提高DMRS的接收信噪比。
如果网络设备作为发送端，终端设备作为接收端，则执行520和530；如果网络设备作为接收端，终端设备作为发送端，则执行540和550。
在630中，网络设备通过该第一端口，在该DMRS样式指示的资源上映射终端设备的DMRS，且在该静默样式指示的资源上不映射数据。
在640中，该网络终端设备通过该第一端口，在该DMRS样式指示的资源上获取终端设备的DMRS，且在该静默样式指示的资源上假设数据功率为零。
在650中，终端设备通过该第一端口，在该DMRS样式指示的资源上映射终端设备的DMRS，且在该静默样式指示的资源上不映射数据。
在660中，网络设备通过该第一端口，在该DMRS样式指示的资源上获取终端设备的DMRS，且在该静默样式指示的资源上假设数据功率为零。
这样，在DMRS样式可以灵活配置的***中，能够有效的保护DMRS的收发，使其不会受到其它数据的干扰，从而提高DMRS的接收信噪比，改善***的性能。
应理解，这里所说的在DMRS样式指示的资源上映射终端设备的DMRS，可以理解为在DMRS样式指示的资源上发送DMRS；在静默样式指示的资源上不映射数据，可以理解为在静默样式指示的资源上不发送任何数据；在DMRS样式指示的资源上获取终端设备的DMRS，可以理解为在DMRS样式指示的资源上接收终端设备发送的DMRS；在静默样式指示的资源上假设数据功率为零，可以理解为在静默样式指示的资源上不接收数据。
还应理解，本发明实施例中，在静默资源上不发送数据或不接收数据，所述的数据即包括业务数据也包括参考信号，也就是说，在静默样式指示的静默资源上，即不会传输业务数据，也不会传输DMRS，该静默资源上不传输任何信号。
具体地说，网络设备确定了DMRS样式和静默样式后，就可以根据该DMRS样式，在该DMRS样式指示的资源上传输DMRS，并在该静默样式指示的资源上不传输任何数据。同样，终端设备获取网络设备配置的DMRS样式静默样式后，可以根据该DMRS样式，在该DMRS样式指示的资源上传输DMRS，并在该静默样式指示的资源上不传输数据。例如，终端设备可以根据网络设备为自己配置的端口号以及该DMRS样式，确定该DMRS样式指示的资源的位置，并根据网络设备为自己配置的端口号以及该静默样式，确定该静默样式指示的资源的位置。
可选地，网络设备和终端设备在确定了DMRS样式和静默样式后，可以根据第一端口的端口号，以及
Figure PCTCN2016100487-appb-000004
来确定DMRS样式指示的资源以及静默样式指示的资源，其中，m＝0,1,...3NRB-1，NRB是以资源块为单位的带宽，这些带宽被用于为终端设备提供数据服务，
Figure PCTCN2016100487-appb-000005
其中
Figure PCTCN2016100487-appb-000006
表示每个资源块包含的子载波数，不同端口vshift取值不同，例如端口1，vshift为1；端口2，vshift为2；端口3，vshift为3。
应理解，上述方法是以频分的方式实现不同端口DMRS的复用，也可以采用码分或者时分，上述方法只是为了举例说明本发明的可实现性，并不限定本发明的保护范围。
下面举例说明网络设备和终端设备，如何根据DMRS样式和静默样式和端口号，确定DMRS样式指示的资源的位置以及静默样式指示的资源的位置。例如图7示出的3端口***中的三个端口对应的DMRS样式和静默样式，假设网络设备为的哥端口配置的DMRS样式和静默样式是相同的，NRB＝1，
Figure PCTCN2016100487-appb-000007
当m＝0时，在第一个符号上即l＝1，vshift＝1时即端口1对应的子载波位置k＝1，vshift＝2时即端口2对应的子载波位置k＝2，vshift＝3时即端口3对应的子载波位置k＝3；而在第一个符号之后的符号上即l≠1，DMRS样式和静默样式指示的资源中，资源单元在时域上连续分布，vshift＝-1时即端口1对应的子载波位置12*1/2+1＝7，vshift＝2时即端口2对应的子载波位置k＝6，vshift＝3时即端口3对应的子载波位置k＝5。这里端口号vshift在公式中可以取正值也可以取负值。
网络设备为终端设备配置静默样式，可以通过隐式静态配置、显式动态配置或者显式半静态配制的方式。
以下行传输为例，上述的静默样式可以通过隐式静态配置的方式来实现，即网络设备在对终端设备进行调度时，不同端口上采用相同的DMRS样式，在其他端口传输DMRS的资源上，该终端设备不传输数据。该终端设备默认其他端口上的DMRS样式，与当前端口的DMRS样式相同，并且在接收信号时，假设其他端口传输DMRS的资源上的信号功率为零。
上述的静默样式也可以通过显式动态配置的方式来实现，即在网络设备的调度信令中同时包括第一资源指示信息，所述第一资源指示信息用于指示当前终端设备所使用的DMRS样式和静默样式，终端设备接收到调度信令后，根据该静默样式确定需要静默的资源单元的位置，并在接收数据时，假设该静默样式所指示的资源上的信号功率为零。
上述的静默样式还可以通过显式半静态配置的方式来实现，即在网络设备的调度信令中同时包括第一样式标识，该第一样式标识用于指示网络设备的多个端口中每个端口对应的DMRS，网络设备通过高层信令向终端设备发送预设的多个由DMRS样式组成的DMRS样式组，每一个DMRS样式组是由网络设备的每个端口对应可能的DMRS样式组成的。网络设备通过下行调度信令动态通知终端设备该样式标识。终端设备获得该样式标识后，就能够在获得的多个DMRS样式中，确定当前每个端口对应的DMRS样式，从而确定第一端口对应的静默样式所指示的资源单元的位置，并假设在相应的 静默资源单元上的信号功率为零。
基于上面的描述，对于静默样式的配置方式可以是显式的、半静态的；或者显式的、动态的；或者隐式的、静态的。其中，隐式静态的配置方法虽然不需要增加额外的配置开销，但是会对调度造成很大的限制，影响***性能和客户体验；显式动态的配置方式最为灵活，但是需要大量宝贵的物理层资源用于传输配置信息。显式半静态兼顾了灵活和开销两方面，因而显式半静态的配置方式是较为优选的。
下面结合图8至图10，基于上述的几种静默样式的配制方式，详细地描述本发明实施例的传输DMRS的方法。
方式1
显式、动态的方式
作为另一个实施例，如图8所示的传输DMRS的方法，在630至660之前，该方法还包括670，这时，620包括680和690，即620可以由621和622替代。
670，网络设备向终端设备发送第一资源指示信息，该第一资源指示信息用于指示该DMRS样式和该静默样式。
621，终端设备接收网络设备发送的第一资源指示信息，该第一资源指示信息用于指示该DMRS样式和该静默样式。
622，终端设备根据该第一资源指示信息，确定该第一端口对应的该DMRS样式，和该第一端口对应的该静默样式。
以图1中的eNodeB 10、UE 20和UE 30为例进行说明。
对于下行传输，eNodeB 10对UE 20进行调度时，首先确定被调度的UE 20采用的接收端口、DMRS样式和静默样式，并将包括UE 20采用的端口号例如为第一端口的端口号、DMRS样式和静默样式在内的调度信息通过物理层信令发送给UE 20，其中，UE 20对应的端口上的静默资源是UE 30对应的端口上用于发送DMRS的资源。eNodeB 10将UE 20的数据映射到相应端口并将数据发送给UE 20，在映射时，eNodeB 10在静默资源上不映射数据。
UE 20通过物理层信令获得第一端口的端口号、第一端口对应的DMRS样式和静默样式，并在DMRS样式指示的资源上接收DMRS并根据DMRS进行信道估计，并且在接收其他资源单元上的数据时，假设静默样式指示的 资源上的数据功率为零。
对于上行传输，eNodeB 10对UE 20进行调度时，首先确定被调度的UE 20采用的接收端口、DMRS样式和静默样式，并将包括UE 20采用的端口号例如为第一端口的端口号、DMRS样式和静默样式在内的调度信息通过物理层信令发送给UE 20，其中，UE 20对应的端口上的静默资源是UE 30对应的端口上用于发送DMRS的资源。UE 20通过物理层信令获得第一端口的端口号、当前第一端口的DMRS样式和静默样式。UE 20对其上行数据进行映射并向eNodeB 10发送，这时，在进行数据映射时，UE 20在静默资源上不映射数据。eNodeB 10在第一端口接收UE 20发送的数据，且接收数据时，假设静默样式指示的资源上的数据功率为零。
方式2
显式、半静态的方式
作为另一个实施例，该方法还包括681和682。
681，网络设备向终端设备发送第一样式标识，该第一样式标识用于指示该网络设备的多个端口中的每个端口对应的DMRS样式；
682，终端设备接收网络设备发送的第一样式标识，该第一样式标识用于指示该网络设备的多个端口中的每个端口对应的DMRS样式。
并且进一步地，如图10所示，该方法还包括691至693。这时，620包括623，即620可以由623替代。
691，网络设备确定多个DMRS样式，所述多个DMRS样式包括所述DMRS样式；
692，网络设备向终端设备发送该多个DMRS样式的信息；
693，终端设备接收网络设备发送的多个DMRS样式的信息。
623，终端设备根据该第一样式标识和该多个DMRS样式，确定第一端口对应的DMRS样式，和第一端口对应的静默样式。
以图1中的eNodeB 10、UE 20和UE 30为例进行说明。
对于下行传输，网络设备首先为UE 20确定一组DMRS样式组，并通过高层信令半静态的通知UE 20。
这里以4端口***为例，DMRS样式如图10所示。
第一组:{样式1，样式1，样式1，样式1}
第二组:{样式1，样式1，样式1，样式5}
第三组:{样式1，样式1，样式5，样式5}
第四组:{样式1，样式5，样式5，样式5}
应注意，上述样式组是eNodeB 10根据实际情况，根据长周期进行调整，并半静态的通知UE 20的。也可以是eNodeB 10与UE 20之前预先约定的。每一组中的第一个元对应端口1，第二个元素对应端口2，第三个元素对应端口3，第四个元素对应端口4。例如，在第二组中，端口1、端口2和端口3对应的DMRS样式为样式1，端口4对应的DMRS样式为样式5。
eNodeB 10对UE 20进行调度，并将包括UE 20使用的第一端口的端口号(例如图9示出的端口1)、DMRS样式在内的调度信息通过物理层信令发送给UE 20。这里的DMRS样式可以用上述DMRS样式组标识的二进制数来表示，以上述4组为例，“00”表示第一组的第一样式标识，“01”表示第二组的第一样式标识，“10”表示第三组的第一样式标识，“11”表示第四组的第一样式标识。应注意，这里的每个端口的DMRS样式，所对应的是eNodeB 10最近一次通知UE 20的DMRS样式组中的某个样式组中的DMRS样式。
eNodeB 10将UE 20的数据映射到第一端口并将数据发送给UE 20，在映射时，在其它UE对应的端口上发送DMRS的位置上不映射数据，如图10所示，这里以第二组为例，给出了各个端口上资源映射情况。
对于下行传输，UE 20通过高层信令获得DMRS样式组，UE 20通过物理层信令获得第一端口的端口号和第一样式标识。UE 20根据第一样式标识，从最近一次获得的DMRS样式组中，确定第一端口对应的DMRS样式和其它端口对应的DMRS样式，并进一步地确定第一端口对应的静默样式，这里，端口1对应的静默样式，实际上为端口2至端口4对应的DMRS样式。UE 20在DMRS资源单元上进行信道估计，并且在其他资源单元上接收数据，并且在接收数据时，假设静默样式指示的资源上的数据功率为零。
对于上行传输，eNodeB 10首先为UE 20确定一组DMRS样式组，并通过高层信令半静态的通知UE 20。eNodeB 10对UE 20进行调度，并将包括UE 20使用的第一端口的端口号、第一样式标识在内的调度信息通过物理层信令发送给UE 20。UE 20通过高层信令获得DMRS样式组，通过物理层信令获得第一端口的端口号和该第一样式标识。
UE 20将上行数据进行映射并发送给网络设备，在数据映射时，UE 20 将其他端口用于DMRS的资源确定为第一端口对应的静默资源，并在静默资源上不映射数据。eNodeB 10在UE 20所对应的第一端口上进行数据接收，接收时在DMRS样式指示的资源上进行信道估计，并且在其他资源单元上接收数据，且在接收数据时，假设静默资源上的数据功率为零。
作为另一个实施例，该方法还包括683至685。
683，网络设备向终端设备发送用于指示该DMRS样式的第二资源指示信息；
684，网络设备向终端设备发送用于指示第一端口对应的静默样式的第二样式标识；
685，终端设备接收网络设备发送的第二样式标识和第二资源指示信息。
并且进一步地，如图10所示的本发明是实施例的DMRS的流程交互图，该方法还包括694至696。这时，620包括624，即620可以由624替代。
694，网络设备确定多个静默样式，所述多个静默样式包括所述静默样式；
695，网络设备向所述终端设备发送所述多个静默样式的信息。
696，终端设备接收网络设备发送的多个静默样式的信息。
624，终端设备根据所述第二资源指示信息确定所述DMRS样式，并根据所述第二样式标识，在所述多个静默样式中确定所述第一端口对应的所述静默样式。
也就是说，网络设备向终端设备发送第二资源指示信息指示DMRS样式，并向终端设备发送第二样式标识指示静默样式。终端设备获得第二样式标识后，可与从预设的多个候选静默样式中获得第一端口对应的静默样式，从而确定第一端口对应的静默样式所指示的资源，并假设在相应的静默资源单元上的信号功率为零。
这样，网络设备通过下行调度信令动态指示终端设备上述多个静默样式中的一个所对应的标识。终端设备获得该第二样式标识后，就能够在获得的多个静默样式中，确定当前第一端口对应的静默样式，从而确定第一端口对应的静默样式所指示的资源单元的位置，并假设在相应的静默资源单元上的信号功率为零。例如以图11所示的静默资源的示意图，以网络设备配置了4种静默样式为例，如果网络设备向终端设备发送的第二样式标识指示的静默样式为样式1，那么终端设备就可以根据该第二样式标识，在多个静默样式 中确定第一端口对应的静默样式，从而可以根据第一端口的端口号和该第一端口对应的静默样式，确定该终端设备的静默资源。
需要注意的是，图12示出的是四种静默样式，具体的每一种静默样式所指示的静默资源的具***置，还需要根据预设的规则来确定。例如，终端设备接收到第二样式标识后，首先根据该第二样式标识，在图12示出的四种静默样式中确定该第二样式标识所指示的静默样式，在确定了自己对应的静默样式后，终端设备可以根据自己对应的第一端口的端口号和该静默样式，确定该静默样式具体指示的静默资源的位置，从而在该静默资源上不映射数据，或者在该静默资源上假设信号功率为零。
也就是说，图12所示的静默样式是一个基准的资源映射，不同端口对应的终端设备，在根据获取的静默样式确定相应的静默资源时，需要根据端口号的不同对上述的该静默样式在时域和/或频域添加一个固定的预设偏移，例如在频域上，端口1对应的偏移值为vshift为1；端口2对应的偏移值vshift为2；端口3对应的偏移值vshift为3。
方式3
隐式、静态的方式
前面的方式1和方式2，描述的都是网络设备为该终端设备对应的第一端口配置DMRS样式和静默样式后，需要告知终端设备其应使用的DMRS样式和静默样式。在另一种情况下，如果网络设备为所有端口配置相同的DMRS样式，那么网络设备可以不告知终端设备该第一端口对应的DMRS样式和静默样式，这时，终端设备可以默认该第一端口对应DMRS样式和其它端口对应的DMRS样式是相同的，从而终端设备只需要根据预设的规则，确定其他端口用于发送DMRS的资源单元的位置即可。
方式3中，隐式静态的配置方法无需增加额外的配置开销。
以图1示出的eNodeB 10、UE 20和UE 30为例进行说明。
对于下行传输，eNodeB 10对所有被调度的UE配置相同的DMRS样式。eNodeB 10将包括UE 20使用的第一端口的端口号、DMRS样式的在内的调度信息通过物理层信令发送给UE 20。eNodeB 10将UE 20的数据映射到相应端口并将数据发送给UE 20，在数据映射时，eNodeB 10在其他端口发送DMRS的位置上不映射数据。
UE 20通过物理层信令获得第一端口的端口号和第一端口对应的DMRS 样式。UE 20根据当前第一端口对应的DMRS样式，确定第一端口上的静默资源的位置，确定方法是假设其他端口采用的DMRS样式与当前端口所使用的DMRS样式相同，并根据预设的规则，确定用于其他端口DMRS发送的资源单元的位置。预设的规则可以有很多，例如图7示出的3端口***中的三个端口对应的DMRS样式和静默样式，图7示出的是以频分的方式实现不同端口DMRS的复用。UE 20在DMRS样式指示的资源单元上进行信道估计，并且在其他资源单元上接收数据，且在接收数据时，假设静默资源上的数据功率为零。
对于上行传输，eNodeB 10对所有被调度的UE配置相同的DMRS样式。eNodeB 10将包括UE 20使用的第一端口的端口号、DMRS样式的在内的调度信息通过物理层信令发送给UE 20。
UE 20通过物理层信令获得第一端口的端口号和第一端口对应的DMRS样式。UE 20根据当前第一端口的DMRS样式，确定第一端口上静默样式指示的静默资源的位置，确定方法是假设其他端口采用DMRS样式与当前端口所使用的DMRS样式相同，并根据预设的规则，确定其他端口用于发送DMRS的资源单元的位置。
UE 20将上行数据进行映射并发送，在数据映射时，在静默样式指示的资源单元上不映射数据。eNodeB 10在第一端口接收UE 20发送的数据，接收数据时，eNodeB 10认为所有被eNodeB 10调度的UE 10采用相同的DMRS样式，并确定第一端口对应的静默资源单元的位置，且接收数据时，假设静默资源上的数据功率为零。
基于本发明实施例的方法，网络设备除了为终端设备配置传输DMRS的DMRS样式，还为终端设备配置了静默样式，使得其他终端设备在该静默样式指示的资源上传输DMRS时，不会受到该终端设备的数据传输的干扰，并且该终端设备在传输DMRS时，也不会受到其他终端设备的数据传输的干扰，因此能够提高DMRS的接收信噪比。
应理解，在本发明的各种实施例中，上述各过程的序号的大小并不意味着执行顺序的先后，各过程的执行顺序应以其功能和内在逻辑确定，而不应对本发明实施例的实施过程构成任何限定。
下面将结合图13，描述根据本发明实施例的传输DMRS的网络设备，方法实施例所描述的技术特征可以适用于以下装置实施例。
