Description

一种信道质量指示反馈的方法及设备
本申请要求在2017年3月24日提交中国专利局、申请号为201710184957.X、发明名称为“一种信道质量指示反馈的方法及设备”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
本申请涉及无线通信技术领域，尤其涉及一种信道质量指示反馈的方法及设备。
背景技术
在长期演进(Long Term Evolution，LTE)系统中，基站在向终端发送数据时，将首先对待发送数据进行调制编码；其中，基站侧有多种等级的调制编码方案(Modulation and Coding Scheme，MCS)，且不同等级的MCS适用于不同的信道状况，比如，当前信道质量较好，基站侧可以选择传输码率高，编码效率高但可靠性较低的高等级MCS，而当信道质量较差时，基站侧可以选择传输码率较低、编码效率低但可靠性较高的低等级MCS；然后，将调制编码后的数据发送至终端侧；而终端侧在接收到调制编码的数据后，将首先判断该数据是否被正确接收，如果该数据被正确接收，则向基站侧反馈肯定应答(Acknowledge，ACK)消息，而如果该数据未被正确接收，则向基站侧反馈否定应答(Negative Acknowledge，NACK)消息。
而基站侧在接收到终端发送的NACK消息后，将重新发送上述数据，其中，重新发送上述数据的过程如下：首先确定上次发送该数据时的MCS等级，然后采用上次等级的MCS对该数据再次进行调制编码，发送至终端侧；由于在实际应用中，如果基站在首次采用某种等级的MCS对某一待发送数据进行调制编码，发送至终端侧，而终端侧未能正确收该数据，说明此时的信道质量与MCS等级并不匹配，因此在对数据进行重传时，再采用与上次相同等级的MCS对于重传数据进行编码调制，同样不能保证重传数据的可靠性，即利用与上次数据相同等级的MCS对重传数据进行编码调制，并不能保证终端侧可正确接收重传数据；尤其是在未来的5G通信系统中，致力于提供更高的服务性能，要求所传输的每次数据都尽可能的正确，特别是对于重传数据，因此，如何提高基站下行数据的可靠性，是目前亟需解决的技术问题。

具体实施方式
为了便于理解，示例的给出了与本申请相关概念的说明以供参考，如下所示：
无线通信网络，是一种提供无线通信功能的网络。无线通信网络可以采用不同的通信技术，例如码分多址(code division multiple access,简称CDMA)、宽带码分多址(wideband code division multiple access，简称WCDMA)、时分多址(time division multiple access，TDMA)、频分多址(frequency division multiple access,简称FDMA)、正交频分多址(orthogonal frequency-division multiple access,OFDMA)、单载波频分多址(single Carrier  FDMA，SC-FDMA)、载波侦听多路访问/冲突避免(Carrier Sense Multiple Access with Collision Avoidance)。根据不同网络的容量、速率、时延等因素可以将网络分为2G(generation)网络、3G网络、4G网络或者未来演进网络，如5G网络。典型的2G网络包括全球移动通信系统(global system for mobile communications/general packet radio service，GSM)网络或者通用分组无线业务(general packet radio service，GPRS)网络，典型的3G网络包括通用移动通信系统(universal mobile telecommunications system，UMTS)网络，典型的4G网络包括长期演进(long term evolution,LTE)网络。其中，UMTS网络有时也可以称为通用陆地无线接入网(universal terrestrial radio access network，UTRAN)，LTE网络有时也可以称为演进型通用陆地无线接入网(evolved universal terrestrial radio access network，E-UTRAN)。根据资源分配方式的不同，可以分为蜂窝通信网络和无线局域网络(wireless local area networks，WLAN)，其中，蜂窝通信网络为调度主导，WLAN为竞争主导。前述的2G、3G和4G网络，均为蜂窝通信网络。
用户设备(user equipment，UE)是一种终端设备，可以是可移动的终端设备，也可以是不可移动的终端设备。该设备主要用于接收或者发送业务数据。用户设备可分布于网络中，在不同的网络中用户设备有不同的名称，例如：终端，移动台，用户单元，站台，蜂窝电话，个人数字助理，无线调制解调器，无线通信设备，手持设备，膝上型电脑，无绳电话，无线本地环路台，车载设备等。该用户设备可以经无线接入网(radio access network，RAN)(无线通信网络的接入部分)与一个或多个核心网进行通信，例如与无线接入网交换语音和/或数据。
基站(base station，BS)设备，也可称为基站，是一种部署在无线接入网用以提供无线通信功能的装置。例如在2G网络中提供基站功能的设备包括基地无线收发站(base transceiver station,BTS)和基站控制器(base station controller,BSC)，3G网络中提供基站功能的设备包括节点B(英文NodeB)和无线网络控制器(radio network controller,RNC)，在4G网络中提供基站功能的设备包括演进的节点B(evolved NodeB，eNB)，在WLAN中，提供基站功能的设备为接入点(access point，AP)。在未来5G网络如新无线(New Radio，NR)或LTE+中，提供基站功能的设备包括继续演进的节点B(gNB)，TRP(transmission and reception point，收发点)，或TP(transmission point，传输点)。其中，TRP或TP可以不包括基带部分，仅包括射频部分，也可以包括基带部分和射频部分。
应答消息：UE针对基站发送的下行数据的应答消息，该应答消息具体分为肯定应答
(Acknowledge，ACK)消息和否定应答(Negative Acknowledge，NACK)消息；在UE正确接收下行数据时，将向基站反馈ACK消息，否则，反馈NACK消息。
调制编码方案(Modulation and Coding Scheme，MCS)：用于对不同的调制和编码方式进行编号，以便系统调用不同的通信策略；其中，MCS分为不同的等级，MCS的等级越高，调制编码的效率越高，但可靠性越低。
信道质量指示(Channel Quality Indicator，CQI)，用于代表当前信道质量的好坏，和信道的信噪比大小相对应。
网络侧设备，是指位于无线通信网络中位于网络侧的设备，可以为接入网网元，如基站或控制器(如有)，或者，也可以为核心网网元，还可以为其他网元。
NR(新无线，new radio)，是指新一代无线接入网络技术，可以应用在未来演进网络，如5G网络中。
下面结合附图，对本申请的技术方案进行介绍：
图1示出了本申请实施例的一种可能的无线通信网络。如图1所示，基站10可向UE20发送下行数据，而UE20在接收到该下行数据时，将根据该下行数据的校验信息，判断该下行数据是否被正确接收，且向基站10反馈应答消息；当UE20正确接收下行数据时，将向基站10反馈ACK消息，而UE20在未正确接收下行数据时，将向基站反馈NAC消息。
由于NR中，致力于提供更高的服务性能，要求所传输的每次数据都尽可能的正确，特别是对于重传数据。
基于此，本申请提供一种信道质量指示反馈的方法，其主要原理是UE将应答消息和CQI一起上报给基站，从而使得基站基于CQI，选择相匹配的MCS，对下行数据进行调整编码，从而提高UE接收数据的正确性。
本申请实施例中部分场景以无线通信网络中4G网络的场景为例进行说明，应当指出的是，本发明实施例中的方案还可以应用于其他无线通信网络中，相应的名称也可以用其他无线通信网络中的对应功能的名称进行替代。
需指出的是，本发明实施例中的方法或装置可以应用于网络侧设备和用户设备之间，也可以应用于网络侧设备和网络侧设备(如宏基站和微基站)之间，还可以应用于用户设备和用户设备(如D2D场景)之间，在本发明所有实施例中，以网络侧设备和UE之间的通信为例进行描述。
图2为本申请实施例提供的一种信道质量指示反馈的方法的流程，如图2所示，包括：
S21：终端设备获取下行数据的应答消息和信道状态信息，所述应答消息包括肯定应答消息和/或否定应答消息，所述信道状态信息和所述应答消息指示网络设备发送下行数据的调制编码方案；
具体的，所述应答消息指示所述网络侧设备调整调制编码方案的方向，所述调整所述调制编码方案的方向为提高所述调制编码方案的等级，或降低所述调制编码方案的等级；所述信道状态信息指示所述网络侧设备调整所述调整编码方案的等级的偏移量，所述调制编码方案用于所述网络侧设备对所述下行数据进行调制编码；且应答消息和所述信道状态信息可独立进行信道编码，且所述应答消息采用第一编码方式进行编码，所述信道状态信息采用第二编码方式进行编码。
S22：终端设备发送所述应答消息和信道状态信息至所述网络侧设备。
S23：网络侧设备根据所述应答消息和信道状态信息，调整发送下行数据的调制编码方案。
可以看出，终端设备将应答消息和信道状态信息同时发送至网络侧设备，而网络侧设备可根据应答消息和信息状态信息，确定与当前通信环境相匹配的MCS方案，对下行数据进行编码，从而提高网络侧设备与终端设备传输数据的正确性。
在一种实施方式，终端设备仅当应答消息为NACK时，才上报CQI，如图3所示，实现方式具体如下：
S31：网络侧设备发送下行数据；
S32：终端设备确定下行数据是否被正确接收，且在下行数据被正确接收时，确定应答消息为NCAK；
S33：终端设备获取所述下行数据所对应下行信道的第一CQI；
具体的，所述终端设备可根据所述下行数据中携带的解调导频信号，确定当前下行信道的CQI，所述解调导频信号用于所述终端设备对所述下行数据进行解调；
和/或，
所述终端设备根据所述下行数据相对应的测量导频信号，确定当前下行信道的CQI，所述测量导频信号用于确定当前下行信道的信道状态。
S34：所述终端设备发送NACK和CQI至网络侧设备；
进一步的，所述终端设备可通过第一物理上行控制信道，将所述CQI发送至所述网络侧设备；通过第二物理上行控制信道，将所述否定应答消息发送至所述网络侧设备；其中，第一物理上行控制信息和第二物理上行控制信息可采用时分复用的方式，且第二物理上行控制信息在先。
或者，所述终端设备可通过第三物理上行控制信道，将所述CQI和所述否定应答消息发送至所述网络侧设备，其中，所述CQI采用第一编码方式映射到所述第三物理上行控制信道，所述否定应答消息采用第二编码方式映射到所述第三物理上行控制信道。
更进一步的，所述第一物理上行控制信道、第二物理上行控制信道或第三物理上行控制信道为信道容量小于预设值的物理上行控制信道；由于在实际应用中，整个无线通信网络中有大容量的物理小行控制信道和小容量的物理上行控制信道，而由于NACK和CQI的数据量均较小，因此，在本申请中，采用小容量的物理上行控制信道，可节省系统资源。
具体的，CQI上报所占第一物理上行控制信道的频域和码域资源可由基站通过高层信令或物理层信息配置，配置该信令是用户专署的。
S35：网络侧设备基于NACK和第一CQI调整MCS，所述MCS用于对下行数据进行调制编码。
在本申请中，NACK可具体指示调整MCS的方向，比如，降低MCS的等级，而CQI可具体为调整NACK的等级的编移量；比如，当CQI为0时，表示MCS的等级调整1个等级，CQI为1时，表示MCS的等级调整2个等级。
在一种实施方式中，终端设备在应答消息为NACK和ACK时，均上报CQI，如图4所示，实现方式具体如下：
S41：网络侧设备发送下行数据；
S42：终端设备确定下行数据是否被正确接收；如果否，执行S43；如果是，执行步骤S47；
S43：终端设备确定应答消息为NACK；
S44：终端设备获取下行数据所对应下行信道的第二CQI；
S45：终端设备发送NACK和第二CQI至网络侧设备；
S46：网络侧设备根据NACK和CQI调整MCS；
S47：终端设备确定应答消息为ACK；
S48：终端设备获取下行数据所对应下行信道的第三CQI；
S49：终端设备发送ACK和第三CQI至网络侧设备；
S410：网络侧设备根据ACK和第三CQI对下行数据进行调制编码。
应当指出，关于确定第二CQI和第三CQI，以及发送NACK和第二CQI、发送ACK和第三CQI的过程，可具体参见上述论述，在此不再赘述。
在一种示例中，CQI占1个指示比特，比如可用0代表不偏移，1代表MCS偏移1个单位，而ACK/NACK也占1个指示比特，而用ACK用于表示MCS等级提高，而NACK表示MCS等级降低。
比如，CQI的0表示偏移，CQI的1表示调整MCS的一个等级，而用ACK表示提高MCS的等级，NACK表示降低NACK的等级，具体如表1所示。
CQ 0(NACK) 1(ACK)
0 不偏移 不偏移
1 降低1个等级 升高1个等级。
表1
再比如，CQI的0表示偏移，CQI的1表示调整MAC的二个等级，而用ACK表示提高MCS的等级，NACK表示降低NACK的等级，具体如表2所示。
CQI 0(NACK) 1(ACK)
0 不偏移 不偏移
1 降低2个等级 升高1个等级。
表2
在本申请中，CQI和ACK/NACK的上报模式可具体由高层信令指令，而终端设备在接收到上报模式配置指令后，将决定采用何种模式上报CQI和ACK/NACK。
采用本申请实施例的方式，既可以保证传输可靠性，又能避免传输效果过低的调度。同时也可以避免CQI反馈增强带来的开销猛增的问题。
在另一种可行实施方式中，本申请提供的信道质量指示反馈的方法，可具体如下：终端设备确定下行数据的应答消息和信道状态，所述应答消息可具体为ACK和NACK；所述信道状态可具体为当前信道的信噪比等；在本申请中，ACK应答消息所对应的信道状态可具体为第二信道状态，而NACK应答消息所对应的信道状态可具体为第一信道状态；而在本申请中，可具体根据ACK/NACK和信道状态，确定第一信道状态信息，所述第一信道状态信息可具体为调整MCS等级的偏移量，比如，第一信道状态信息可具体为0，表示MCS不进行偏移，而第一信道状态信息也可具体为1，表示MCS偏移1个等级。关于NCK、NACK以及信道状态信息的详细介绍，可具体参见上述论述，在此不再赘述；而网络侧设备可根据上述应答消息和第一信道状态信息，确定信息状态。
