Description

信道状态信息的上报方法及相关设备 技术领域
本申请涉及通信技术领域，尤其涉及一种信道状态信息的上报方法及相关设备。
背景技术
在无线通信领域，信道状态信息(Channel State Information，CSI)是通信链路的信道属性。CSI描述了信号在每条传输路径上的衰弱因子。CSI可以使通信系统适应当前的信道条件，在多天线系统中为高可靠性高速率的通信提供了保障。CSI是终端设备(User Equipment，UE)上报给网络设备的信息。CSI包括信道质量指示(Channel Quality Indicator，CQI)、秩指示(Rank Indication，RI)和预编码矩阵指示(Precoding Matrix Indicator，PMI)，等等。
在基于信道互易性的下行传输中，终端设备可以不上报PMI，只上报CQI等其他信道信息，这种CSI上报方式称为无PMI上报的CSI上报方式。在无PMI上报的CSI上报方式下，网络设备基于信道互易性和信道探测参考信号(Sounding Reference Signal，SRS)获得下行信道信息，然后基于获得的下行信道信息计算下行预编码矩阵。

附图说明
为了更清楚地说明本申请实施例或现有技术中的技术方案，下面将对实施例或现有技术描述中所需要使用的附图作简单地介绍，显而易见地，下面描述中的附图仅仅是本申请的一些实施例，对于本领域普通技术人员来讲，在不付出创造性劳动的前提下，还可以根据这些附图获得其他的附图。

具体实施方式
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，所描述的实施例仅仅是本申请一部分的实施例，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，都应当属于本申请保护的范围。
以下分别进行详细说明。
本申请的说明书和权利要求书及所述附图中的术语“第一”、“第二”、“第三”和“第四”等是用于区别不同对象，而不是用于描述特定顺序。此外，术语“包括”和“具有”以及它们任何变形，意图在于覆盖不排他的包含。例如包含了一系列步骤或单元的过程、方法、系统、产品或设备没有限定于已列出的步骤或单元，而是可选地还包括没有列出的步骤或单元，或可选地还包括对于这些过 程、方法、产品或设备固有的其它步骤或单元。
在本文中提及“实施例”意味着，结合实施例描述的特定特征、结构或特性可以包含在本申请的至少一个实施例中。在说明书中的各个位置出现该短语并不一定均是指相同的实施例，也不是与其它实施例互斥的独立的或备选的实施例。本领域技术人员显式地和隐式地理解的是，本文所描述的实施例可以与其它实施例相结合。
下面结合附图对本申请的实施例进行描述。
请参见图1，图1是本申请实施例公开的一种网络构架的示意图。图1所示的网络构架包括终端设备和网络设备。终端设备和网络设备通过无线信号建立连接。在建立连接后，终端设备通过无线信号给网络设备进行上行传输，比如终端设备给网络设备上报CSI等；网络设备通过无线信号给终端设备进行下行传输，比如网络设备给终端设备传输信令等。
在无PMI上报的CSI上报方式下，网络设备基于信道互易性和SRS获得下行信道信息，然后网络设备基于获得的下行信道信息计算下行预编码矩阵。由于网络设备的信道互易性有可能是理想的也有可能是非理想的，那么网络设备根据信道互易性获得的下行信道信息的准确性是难以保证的。在不同的信道互易性可靠性情况下，如果终端设备采用相同的测量方式来估计信道状态信息(比如RI/CQI)，这样可能会导致终端设备在某些场景下估计得到的信道状态信息不准确。
为了解决上述问题，在本申请中，终端设备和网络设备预先约定好至少一种在无PMI的CSI上报方式下用于进行CQI估计的CQI测量方式。在进行CQI估计之前，终端设备先确定当前在无PMI的CSI上报方式下所使用的一种CQI测量方式；然后终端设备再基于确定得到的CQI测量方式进行CQI估计，最后终端设备向网络设备反馈估计得到的CQI。
可见，相较于现有技术，在本申请中，在无PMI的CSI上报方式下用于进行CQI估计的CQI测量方式可以多于一种，在不同场景下，终端设备确定在无PMI的CSI上报方式下所使用的CQI测量方式可以是不同的，这样尽可能的避免终端设备在不同场景下采用相同的CQI测量方式进行CQI估计，而导致在某些场景下估计得到的CQI不准确的问题，进而提升了信道状态信息 的准确性。
其中，终端设备是一种向用户提供语音和/或数据连通性的设备，例如，具有无线连接功能的手持式设备、车载设备等。常见的终端设备例如包括：手机、平板电脑、笔记本电脑、掌上电脑、移动互联网设备(mobile internet device，MID)、可穿戴设备，例如智能手表、智能手环、计步器等。
其中，网络设备是指网络侧的节点设备，例如，网络设备可以是蜂窝网络中接入网侧的无线接入网(Radio Access Network，RAN)设备，所谓RAN设备即是一种将终端设备接入到无线网络的设备，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 NodeB，或Home Node B，HNB)、基带单元(BaseBand Unit，BBU)、管理实体(Mobility Management Entity，MME)；再如，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)等。
下面结合图1所示的网络构架对本申请实施例提供的数据处理方法进行详细说明。
请参见图2，图2为本申请实施例提供的一种信道状态信息的上报方法的流程示意图，该方法包括：
步骤201：终端设备确定在无PMI的CSI上报方式下所使用的CQI测量方式。
具体地，终端设备和网络设备预先约定好至少一种在无PMI的CSI上报方式下用于进行CQI估计的CQI测量方式。其中，CQI测量方式为：基于码本中的预编码矩阵进行CQI估计的第一CQI测量方式；只基于干扰测量结果进行CQI估计的第二CQI测量方式；基于部分下行接收天线对应的下行信道信息进行CQI估计的第三CQI测量方式；或者，基于赋形的CSI-RS端口进行CQI估计的第四CQI测量方式。其中，至少一种CQI测量方式是上述第一CQI测量方式、上述第二CQI测量方式、上述第三CQI测量方式和上述第四CQI测量方式中的至少一种。
步骤202：所述终端设备基于确定的在无PMI的CSI上报方式下所使用的CQI测量方式进行CQI估计。
步骤203：所述终端设备向网络设备上报估计得到的CQI；所述网络设备接收来自所述终端设备上报的CQI。
可见，相较于现有技术，在本申请中，在无PMI的CSI上报方式下用于进行CQI估计的CQI测量方式可以多于一种，在不同场景下，终端设备确定在无PMI的CSI上报方式下所使用的CQI测量方式可以是不同的，这样尽可能的避免终端设备在不同场景下采用相同的CQI测量方式进行CQI估计，而导致在某些场景下估计得到的CQI不准确的问题，进而提升了信道状态信息的准确性。
在一示例中，在步骤201之前，所述方法还包括：
所述网络设备向所述终端设备发送第一指示信息，所述第一指示信息用于指示使用无PMI的CSI上报方式；所述终端设备接收来自所述网络设备的第一指示信息；所述终端设备根据所述第一指示信息确定使用无PMI的CSI上报方式。
具体地，网络设备向终端设备发送下行信令，该下行信令承载上述第一指示信息。下行信令可以是网络设备向终端设备发送的高层信令，如无线资源控制协议(Radio Resource Control，RRC)信令。其中，RRC信令承载第一指示信息的具体做法可以有：在RRC中增加1bit的信息(即第一指示信息)指示是使用无PMI的CSI上报方式，还是使用有PMI的CSI上报方式。比如，这1bit的值为1时，表示使用无PMI的CSI上报方式，这1bit的值为0时，表示使用有PMI的CSI上报方式。在无PMI的CSI上报方式下，终端设备进行CSI上报时，不上报PMI，终端设备可仅上报CQI，或者，终端设备上报CQI、RI和CSI-RS资源指示信息(CSI-RS Resource Indicator，CRI)等其他CSI信息。
在一示例中，在终端设备接收到所述第一指示信息之前，终端设备可以采用默认的CSI上报方式。例如，在终端设备接收到所述第一指示信息之前，终端设备可以默认采用有PMI的CSI上报方式；在终端设备接收到所述第一指示信息之后，终端设备再根据所述第一指示信息确定后续所使用无PMI的CSI 上报方式。
在一示例中，在步骤201之前，所述方法还包括：
所述网络设备向终端设备发送第二指示信息，所述第二指示信息用于指示在无PMI的CSI上报方式下CQI估计所使用的CQI测量方式；所述终端设备接收来自所述网络设备的第二指示信息；所述终端设备确定在无PMI的CSI上报方式下所使用的CQI测量方式的具体实施方式有：所述终端设备根据所述第二指示信息从至少一种CQI测量方式中确定在无PMI的CSI上报方式下所使用的CQI测量方式。
需要说明的是，此处的至少一种CQI测量方式即上述所述的至少一种CQI测量方式，在此不再叙述。
具体地，网络设备向终端设备发送下行信令，该下行信令承载上述第二指示信息。其中，承载第二指示信息的下行信令和承载第一指示信息的下行信令可以是同一信令，也可以是不同的信令，在此不作限定。假设承载第二指示信息的下行信令和承载第一指示信息的下行信令均是RRC信令，RRC信令承载第二指示信息的具体做法可以有：在RRC承载第一指示信息的基础上，再在RRC中增加2bit的信息(即第二指示信息)指示在无PMI的CSI上报方式下CQI估计所使用的CQI测量方式。比如，这2bit的值为00时，表示在无PMI的CSI上报方式下所使用的CQI测量方式为上述第一CQI测量方式，这2bit的值为01时，表示在无PMI的CSI上报方式下所使用的CQI测量方式为上述第二CQI测量方式，这2bit的值为10时，表示在无PMI的CSI上报方式下所使用的CQI测量方式为上述第三CQI测量方式，这2bit的值为11时，表示在无PMI的CSI上报方式下所使用的CQI测量方式为上述第四CQI测量方式。
在一示例中，在终端设备接收到所述第二指示信息之前，终端设备可以采用默认的CQI测量方式。例如，在终端设备接收到所述第二指示信息之前，终端设备可以默认采用上述第二CQI测量方式；在终端设备接收到所述第二指示信息之后，终端设备再根据所述第二指示信息确定后续所采用的CQI测量方式。
在一示例中，若所述终端设备确定在无PMI的CSI上报方式下所使用的CQI测量方式为所述第一CQI测量方式，在步骤201之前，所述方法还包括：
所述网络设备向所述终端设备发送第三指示信息，所述第三指示信息用于指示在无PMI的CSI上报方式下CQI估计所使用的码本类型；所述终端设备接收来自所述网络设备的第三指示信息；以上步骤S202所述终端设备基于确定的在无PMI的CSI上报方式下所使用的CQI测量方式进行CQI估计的具体实施方式有：所述终端设备根据所述第三指示信息从预定义的至少一个码本类型中确定在无PMI上报的反馈方式下CQI估计所用的码本类型；所述终端设备根据所述码本类型的码本进行CQI估计。
例如，所述至少一个码本类型是终端设备和网络设备预先约定好的两个码本类型，这两个码本类型比如有：Type 1codebook和Type 2codebook。其中，Type 1codebook包含低精度的码本，Type 2codebook包含高精度的量化码本。
具体地，网络设备向终端设备发送下行信令，该下行信令承载上述第三指示信息。其中，承载第三指示信息的下行信令、承载第二指示信息的下行信令和承载第一指示信息的下行信令可以是同一信令，也可以是不同的信令，在此不作限定。假设承载第一指示信息、第二指示信息和第三指示信息的下行信令均是RRC信令，RRC信令承载第三指示信息的具体做法可以有：在RRC承载第一指示信息和第二指示信息的基础上，再在RRC中增加1bit的信息(即第三指示信息)指示指示在无PMI的CSI上报方式下CQI估计所使用的码本类型。比如，这1bit的值为0时，表示在无PMI的CSI上报方式下CQI估计所使用的码本类型为Type 1codebook，这1bit的值为1时，表示在无PMI的CSI上报方式下CQI估计所使用的码本类型为Type 2codebook。
在一示例中，若所述终端设备确定在无PMI的CSI上报方式下所使用的CQI测量方式为所述第一CQI测量方式，在步骤201之前，所述方法还包括：
所述网络设备向所述终端设备发送第四指示信息，所述第四指示信息用于至少在指定码本类型中用于在无PMI的CSI上报方式下CQI估计所使用的码本；所述终端设备接收来自所述网络设备的第四指示信息；以上步骤S202所述终端设备基于确定的在无PMI的CSI上报方式下所使用的CQI测量方式进行CQI估计的具体实施方式有：所述终端设备根据所述第四指示信息从所述指定码本类型中确定在无PMI上报的上报方式下CQI估计所使用的码本；所述终端设备根据所述码本进行CQI估计。
具体地，假设指定码本类型为Type 1codebook，其中Type 1codebook中的不同配置参数对应不同的码本。所述第四指示信息用于指示Type 1codebook的一组配置参数，终端设备基于指示的这组配置参数可以从Type 1codebook中确定一个码本，然后终端设备基于确定的码本进行CQI估计。其中，码本类型的配置参数可以包括：天线端口数，波束总数，采样频率，一个波束组包含的波束数，波束组数，天线阵列块(Panel)数，极化数等中的至少一项。
在一示例中，若所述终端设备确定在无PMI的CSI上报方式下所使用的CQI测量方式为所述第一CQI测量方式，以上步骤S202所述终端设备基于确定的在无PMI的CSI上报方式下所使用的CQI测量方式进行CQI估计的具体实施方式有：所述终端设备根据目标码本或者目标码本的子集进行CQI估计，所述目标码本为所述终端设备在有PMI上报的CSI上报方式下进行CSI测量所使用的码本。
在一种实施方式中，目标码本为所述终端设备最近一次在有PMI上报的CSI上报方式下进行CSI测量所使用的码本。比如，终端设备中记录有2次在在有PMI上报的CSI上报方式下进行CSI测量所使用的码本的记录，如在时刻1，终端设备在有PMI上报的CSI上报方式下进行CSI测量所使用的码本1，在时刻2，终端设备在有PMI上报的CSI上报方式下进行CSI测量所使用的码本2，假如时刻2距离当前系统时间短与时刻1距离当前系统时间，那么码本2为目标码本。
在另一种实施方式中，网络设备通过下行信令(如高层信令)为终端设备配置在有PMI上报的CSI上报方式下进行CSI测量所使用的码本，该下行信令同时也用于配置在无PMI上报的CSI上报方式下进行CSI测量所使用的码本，即不需要为无PMI上报的CSI上报方式再单独配置码本。码本可以包括多个不同的子集。在这种情况下，两种上报方式仍然可以采用独立的码本子集约束用于CQI估计，例如两种上报方式采用独立的码本子集约束指示信息。比如在有PMI上报的CSI上报方式下采用目标码本中的子集1进行CQI估计，在无PMI上报的CSI上报方式下采用目标码本中的子集2进行CQI估计，子集1和子集2均是目标码本中独立的子集。
需要说明的是，结合上述两种示例，当终端设备没有接收到来自网络设备 的第三指示信息时，终端设备采用上述目标码本或上述目标码本的子集进行CQI估计。当终端设备接收到来自网络设备的第三指示信息时，终端设备采用第三指示信息指示的在无PMI的CSI上报方式下CQI估计所使用的码本类型的码本进行CQI估计。
另外，上述第一CQI测量方式可用于终端设备下行接收天线的数目等于上行发送天线的数目的场景。在该场景下，网络设备能够通过SRS获得完整的下行信道信息，因此终端设备可以基于第一CQI测量方式能够获得较为准确的CQI估计。
在一示例中，若所述终端设备确定在无PMI的CSI上报方式下所使用的CQI测量方式为所述第二CQI测量方式，终端设备基于第二CQI测量方式进行CQI估计。
具体地，终端设备的CQI估计结果只反映下行干扰的大小(该干扰同时包含了噪声部分)，不包含信号质量的信息，网络设备可以根据信道互易性获得下行信号信息，从而结合终端设备反馈的干扰大小获得最终的CQI。例如，假设终端设备进行干扰测量得到的干扰大小为IDL，则相应的信干比SINR＝1/IDL，其中，假设信道部分的取值为1。终端设备基于该SINR进行CQI计算和上报。
在一示例中，若所述终端设备确定在无PMI的CSI上报方式下所使用的CQI测量方式为所述第三CQI测量方式，所述部分下行接收天线是所述终端设备在上行传输时用于发送上行信号的天线。
具体地，如果终端设备上行发送天线的数目少于下行接收天线的数目，则终端设备可以只基于上行发送天线对应的下行信道信息进行CQI估计，从而保证CQI估计的准确性，因此，所述部分下行接收天线是终端设备在上行传输时用于发送上行信号的天线，即终端设备不基于未用于上行传输的天线上的信道信息进行CQI估计。
在一示例中，若所述终端设备确定在无PMI的CSI上报方式下所使用的CQI测量方式为所述第四CQI测量方式，以上步骤S202所述终端设备基于确定的在无PMI的CSI上报方式下所使用的CQI测量方式进行CQI估计的具体实施方式有：所述终端设备基于从目标CSI-RS端口上获得的下行信道信息进 行CQI估计，所述目标CSI-RS端口为所述终端设备从所述赋形的CSI-RS端口中选取的至少一个CSI-RS端口。
具体地，终端设备可以将所选择的目标CSI-RS端口的指示信息也上报给网络设备，例如可以将目标CSI-RS端口的数目作为RI上报。所述赋形的CSI-RS端口的数目一般为终端设备下行传输支持的最大传输层数，每个赋形后的CSI-RS端口得到的下行信道对应一个下行传输层的等效信道，终端设备基于赋形后的CSI-RS端口得到每个下行传输层的等效信道，从而进行CQI和RI等信道状态信息估计。
在一示例中，所述方法还包括：
所述终端设备基于所述确定的在无PMI的CSI上报方式下所使用的CQI测量方式估计RI；所述终端设备上报估计得到的RI；所述网络设备接收来自所述终端设备上报的RI。
具体地，假设在无PMI的CSI上报方式下所使用的CQI测量方式为上述第一CQI测量方式，那么终端设备也根据第一CQI测量方式进行RI估计。又假设在无PMI的CSI上报方式下所使用的CQI测量方式为上述第二CQI测量方式，那么终端设备也根据第二CQI测量方式进行RI估计，等等。
进一步地，RI估计和CQI估计是采用相同的CQI测量方式在同一个估计过程中完成的，终端设备估计出RI后，同时也估计出该RI对应的CQI。
