Description

一种导频配置、信道测量方法及通信设备
本申请要求在2017年8月10日提交中国专利局、申请号为201710682645.1、发明名称为“一种导频配置、信道测量方法及通信设备”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本申请涉及通信技术领域，特别涉及一种导频配置、信道测量方法及通信设备。
背景技术
MIMO(Multi-Input Multiple-Output，多输入多输出)技术作为重要的提高传输质量和效率的物理层多天线技术，在新一代通信系统中扮演重要角色。在新一代无线接入技术(New RAT(radio access technology)，NR)系统中或LTE(Long Term Evolution，长期演进)系统支持发射分集，空间复用技术以及波束赋型(BF，Beam Forming)等多种ΜΙΜΟ技术。
为了更好地发挥MIMO技术优势，系统中导频结构也发生了相应的变化。通常来说，基站发送的下行导频包括解调导频(即，解调参考信号(Demodulation Reference Signal，DMRS))和测量导频(即，信道状态指示参考信号(Channel State Indication Reference Signal，CSI-RS))。其中，CSI-RS是一种周期性发送的导频结构，可用于终端进行信道测量，其在一个子帧内有多种图样(Pattern)可选。
目前，在NR系统中，用于进行信道状态信息(Channel State Information，CSI)获取的CSI-RS导频信号在CSI-RS端口密度为1RE/PRB/Port时，定义了四种基本的成员CSI-RS RE图样(component CSI-RS RE pattern)。如图1所示，在一个PRB内，1端口的CSI-RS配置图样由1个资源单元(Resource Element，RE)构成，2端口的CSI-RS配置图样由一个正交频分复用技术(Orthogonal Frequency Division Multiplexing，OFDM)符号上频域相邻的2个RE构成。4端口的CSI-RS配置图样包含两种图样，一种是由一个OFDM符号上频域相邻的4个RE构成(图样a)，另一种由时域相邻2个OFDM符号上频域相邻2个RE的4个RE构成(图样b)。对于更高端口的CSI-RS配置图样可由这些CSI-RS配置图样聚合得到，例如16端口CSI-RS可由4个4端口的CSI-RS配置图样聚合得到。
在实际应用中，终端在进行数据上报时，需要通过CSI-RS进行信道测量。由于NR系统中仅定义了以上的CSI-RS的RE图样和采用聚合的方式生成更高端口的CSI-RS图样，因此对于一个N端口CSI-RS，其在一个PRB内所占用的时频资源位置有多种可能性，而如何通知终端基站配置的N端口CSI-RS所占用的时频资源位置，目前还没有相应的解决方案。

实施例一
本申请实施例中提供一种导频配置方法，该方法可以应用于基站，如图2所示，该方法可以描述如下。
S11：基站根据系统预定义的CSI-RS配置图样确定N端口CSI-RS的配置信息；其中，CSI-RS配置图样用于表征在以一个资源数据块(Physical Resource Block，PRB)中的至少一个正交频分复用OFDM符号为时域单位时，针对不同端口的CSI-RS的RE在时隙中的时频位置的配置，配置信息中至少包括端口数和索引参数，端口数的值为N，索引参数用于指示N端口中每个端口的CSI-RS的资源单元RE在时隙中的时频位置，N为正整数；
S12：基站通过信令将配置信息传输给与基站连接的终端，并根据配置信息传输CSI-RS，以使终端根据配置信息及系统预定义的CSI-RS配置图样，确定N端口CSI-RS的RE在时隙中的时频位置，并使用时频位置上的CSI-RS进行信道测量。
具体地，该基站可以是NR系统，如5G系统中的基站。
本申请实施例中，在S11之前，系统可以以一个PRB内的一个或两个OFDM符号为 时频单位，针对不同端口的CSI-RS定义相应的CSI-RS配置图样。其中，一个PRB的大小在时域上为一个时隙，频域上包含12个子载波。常规情况下，一个时隙包含的OFDM符号数可以为7或14，对应84个或168个资源单元(RE)。
图3A为系统预定义的2端口的CSI-RS配置图像。图3A中，以一个OFDM符号为时频单位来定义CSI-RS配置图样为例。2端口的CSI-RS可以定义有6种CSI-RS配置图样，对应图中标注的“配置1～配置6”，每种配置图样对应1个OFDM符号上的2个相邻RE。
图3B-图3D为系统预定义的4端口的CSI-RS配置图像。其中，4端口的CSI-RS配置图样a，其可以定义3种(图3B所示)或5种CSI-RS配置图样(图3C所示)，每种配置图样对应1个OFDM符号上的4个相邻RE。图3D为4端口的CSI-RS配置图样b，系统可以预定义6种CSI-RS配置图样，每种配置图样对应2个OFDM符号上的2个相邻RE。在实际应用中，4端口CSI-RS图样b的配置也可以不重新定义，而重用2端口的CSI-RS配置图样。
在实际应用中，系统预定义的CSI-RS配置图样可以是基站和终端所公知的。
本申请实施例中，基站根据系统预定义可以配置N端口CSI-RS，并确定N端口CSI-RS的配置信息，该配置信息中至少可以包括端口数和索引参数，其中端口数是与N端口对应的，也就是说端口数的值为N。索引参数可以用于指示N端口中的每个端口或每个聚合部分的端口(即聚合情况下)的CSI-RS的资源单元RE在时隙中的时频位置
索引参数可以包括配置图样索引和OFDM符号索引，其中配置图样索引可以是基站根据系统预定义的CSI-RS配置图样确定的CSI-RS的RE在频域上的位置索引，例如图3A中标注的“配置1”对应的配置图样索引为“1”，表征RE在频域上的位置索引为“1”；图3A中标注的“配置2”对应的配置图样索引为“2”，表征RE在频域上的位置索引是“2”。OFDM符号索引可以用于指示CSI-RS的RE在时域上所对应的OFDM符号所在位置，即在一个时隙内的OFDM符号索引。
在实际应用中，对于4端口CSI-RS的配置图样b，可以仅需告知终端一个OFDM符号的OFDM符号索引，终端便可获知CSI-RS的RE在时隙中的时频位置。例如，若系统预定义的4端口CSI-RS的配置图样b对应图3C中的“配置2”，则基站可仅告知终端表征RE在时隙上的位置的OFDM符号索引，例如OFDM符号索引为4，则终端根据该OFDM符号索引和公知的系统预定义的配置2即可确定CSI-RS的RE在时隙中的时频位置。
当然，在实际应用中，配置信息除了包括上述介绍的参数外，还可以包括其它参数信息，例如CSI-RS的周期，等等。本领域技术人员可以根据实际情况进行设置，本申请实施例对此不作具体限制。
本申请实施例中，由于系统预定义了部分端口(如1端口，2端口和4端口)的CSI-RS配置图样，而更高端口的CSI-RS配置图样可通过系统预定义的CSI-RS配置图样聚合得到。 因此，根据端口数的不同情况，基站可以采用不同方法确定CSI-RS的配置信息，下面分别进行介绍。
情况一：若N＝1，2或4，则基站可以根据系统预定义的CSI-RS配置图样确定CSI-RS的RE在时隙中的索引参数，进而，基站根据N端口的端口数和索引参数即可确定CSI-RS的配置信息。
也就是说，如果基站在配置的1端口，2端口或4端口的CSI-RS时，可以直接根据系统预定义的这几个端口的CSI-RS配置图样确定CSI-RS的RE在时隙中的时频位置。
情况二：若N≥8，则配置信息中还包括聚合参数，该聚合参数用于表征N端口CSI-RS的RE在时隙中的聚合方式。此时，基站可以确定N端口CSI-RS的聚合参数，并根据系统预定义的CSI-RS配置图样分别确定N端口CSI-RS的每个聚合部分的RE在时隙中的索引参数，该聚合参数用于表征N端口CSI-RS的RE在时隙中的聚合方式，进而，基站根据N端口的端口数、索引参数和聚合参数即可确定CSI-RS的配置信息。
在实际应用中，基站通过信令在向连接的终端传输索引参数时，可以采用但不仅限于以下两种方式。
方式一：基站通过信令向终端传输包括N端口CSI-RS的全部RE的配置图样索引和OFDM符号索引。
方式二：基站通过信令向终端传输包括N端口CSI-RS的至少一个RE的配置图样索引和OFDM符号索引。
也就是说，在N≥8时，基站可将用于聚合的每个CSI-RS配置图样的配置图样索引和OFDM符号索引，全部通过信令告知终端；或者，也可将其中一部分，例如一个或者多个CSI-RS配置图样的配置图样索引和OFDM符号索引通过信令告知终端，便于减少配置信息中的数据量。
基站在确定N端口CSI-RS的配置信息后，可根据配置信息将CSI-RS传输给终端，并通过信令(例如高层信令)将配置信息传输给终端，以告知终端N端口CSI-RS的RE在时隙中的时频位置，便于终端根据时频位置上的CSI-RS进行信道测量。
下面通过具体的举例说明本申请实施例的应用场景。
若系统预定义2端口、4端口的CSI-RS配置图样如图3A-3C所示。
场景1：当系统配置一个32端口CSI-RS时，相应的CSI-RS配置图像如图4所示，图中“X”代表字母。若系统预定义此32端口CSI-RS由8个4端口的CSI-RS配置图样(b)聚合得到，图4中标有相同字母的RE表示同一个4端口CSI-RS配置图样。则这8个4端口CSI-RS配置图样对应的索引参数分别是：
·配置2，OFDM符号索引6(字母A所在图样)
·配置3，OFDM符号索引6(字母B所在图样)
·配置5，OFDM符号索引6(字母C所在图样)
·配置6，OFDM符号索引6(字母D所在图样)
·配置2，OFDM符号索引12(字母E所在图样)
·配置3，OFDM符号索引12(字母F所在图样)
·配置5，OFDM符号索引12(字母G所在图样)
·配置6，OFDM符号索引12(字母H所在图样)
其中，“配置”即指配置图像索引。
那么，在配置信息中，基站可以将端口数(即N＝32)，以及以上的所有8个配置图样索引和8个OFDM符号索引通过信令告知终端，或者，也可将2个OFDM符号索引(即6、12)和每个OFDM符号上的4个配置图样索引(即2、3、5、6)通过信令告知终端。
则终端在接收基站根据配置信息发送的CSI-RS，同时接收基站发送的32端口的CSI-RS的配置信息。根据系统预定义的32端口CSI-RS由8个4端口成员CSI-RS RE图样(b)聚合得到，即可确定每个CSI-RS RE图样的时频位置，进行信道测量和CSI计算。
场景2：若系统配置一个N＝4端口的CSI-RS，并采用图样b，则如图5所示。此4端口的CSI-RS配置图样对应的索引参数是：
·配置4，OFDM符号索引4
其中，“配置”即指配置图像索引。
则基站可将此配置图样索引和OFDM符号索引通过信令告知终端。
本申请实施例中，基站通过确定CSI-RS的配置信息，并将配置信息通过信令发送给终端，及根据配置信息将CSI-RS传输给终端，使得终端根据接收的配置信息可获知CSI-RS配置图样的配置图样索引和OFDM符号索引，从而确定CSI-RS的时频位置，实现使用时频位置上的CSI-RS进行信道测量。
实施例二
基于同一发明构思，如图6所示，本申请实施例还提供一种信道测量方法，应用于终端，该方法可以描述如下。
S21：终端接收基站通过信令发送的N端口CSI-RS的配置信息，并根据配置信息接收基站发送的CSI-RS；其中，配置信息中至少包括端口数和索引参数，索引参数用于指示N端口中每个端口的CSI-RS的RE在时隙中的时频位置，N为正整数；
S22：终端根据配置信息以及系统预定义的CSI-RS配置图样确定N端口CSI-RS的RE在时隙中的时频位置；其中，CSI-RS配置图样用于表征在以一个PRB中的至少一个OFDM符号为时域单位时，针对不同端口的CSI-RS的RE在时隙中的时频位置的配置；
S23：终端使用时频位置上的CSI-RS进行信道测量。
具体的，终端可以是处于基站覆盖范围内的设备，如用户终端设备等。
本申请实施例中，终端在接收基站通过高层信令发送的N端口CSI-RS的配置信息，并根据该配置信息接收了基站发送的CSI-RS后，至少可以获得配置信息中包括的端口数和索引参数，其中端口数的值可以是与N端口对应的，例如N＝16时，则端口数的值为16。
索引参数可以包括配置图样索引和OFDM符号索引，配置图样索引为根据系统预定义的CSI-RS配置图样确定的CSI-RS的RE在频域上的位置索引，OFDM符号索引用于指示CSI-RS的RE在时域上所对应的OFDM符号所在位置。
系统预定义的CSI-RS配置图样可以是指系统以一个PRB内的一个或两个OFDM符号为时频单位，针对不同端口的CSI-RS定义相应的CSI-RS配置图样，其为基站和终端所共知的。本申请实施例中，S12中的系统预定义的CSI-RS配置图样可以是终端自动获取的，例如从本地或服务器获取，或者，也可以是从基站获取的，例如从基站发送的下行数据中获取。系统预定义的CSI-RS配置图样可参见前序图3A-图3C所示图样及相关介绍，此处不再赘述。
在S12中，终端可以根据接收的配置信息中的端口数、索引参数以及系统预定义的CSI-RS配置图样来确定CSI-RS的资源单元RE在时隙中的时频位置。
例如，若终端接收基站发送的CSI-RS的端口数为4，同时接收基站发送的CSI-RS的配置信息中的配置图样索引和OFDM符号索引，则终端根据端口数、配置图样索引、OFDM符号索引和系统预定义的CSI-RS配置图样即可确定CSI-RS的资源单元RE在时隙中的时频位置。
若终端接收的配置信息还包括聚合参数，聚合参数可以用于表征CSI-RS的RE在时隙中的聚合方式，则终端可以根据端口数、聚合参数、索引参数以及系统预定义的CSI-RS配置图样确定CSI-RS的每个聚合部分在时隙中的时频位置。
当然，在实际应用中，终端也可以根据系统预定义自动确定聚合参数，例如系统预定义16端口可以是由4个4端口的CSI-RS配置图样a聚合得到，或者可以由4个4端口的CSI-RS配置图样b聚合得到，等等。
终端在根据接收的配置信息和系统预定义的CSI-RS配置图样确定CSI-RS的时频位置后，接口使用时频位置上的CSI-RS进行信道测量和CSI计算。
