Description

信道测量信息的反馈方法、用户设备及基站
本申请要求在2015年12月31日提交中国专利局、申请号为201511033853.6、发明名称为“信道测量信息的反馈方法、用户设备及基站”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
本发明涉及通信技术领域，尤其是涉及一种信道测量信息的反馈方法、用户设备及基站。
背景技术
在长期演进(Long Term Evolution，LTE)通信系统中，信道测量信息是为了让基站能够获得下行传输的干扰情况，由用户设备(user equipment，UE)对下行传输信道进行测量，通过对测量结果的量化获得并上报的。
信道测量信息包括信道质量信息指示(Channel Quality Indicator，CQI)和信道探测参考信号(Sounding Reference Signal，SRS)。UE对下行传输信道进行测量，获得CQI，进而在上行信道将CQI反馈给基站，基站根据反馈回的CQI，确定该UE的调制和编码方式。此外，基站利用上下行信道的互易性，通过上行的SRS估计下行信道的信道状态信息，获得多收发单元系统的信道矩阵。基于信道矩阵，可以在基站通过预编码技术实现多UE在同时同频上的传输，提高系统频谱利用率。
当前标准中，CQI和SRS的反馈包含两种类型，即：周期型反馈和非周期型反馈。
其中，CQI的周期型反馈是通过物理上行控制信道(Physical Uplink Control Channel，PUCCH)进行承载，反馈的时间间隔通过高层无线资源控制(Radio Resource Control，RRC)信令半静态配置实现。CQI的非周期型反馈通过物理上行共享信道(Physical Uplink Shared Channel，PUSCH)进行 承载，反馈通过接收下行控制信息(Downlink Control Information，DCI)进行触发，UE每次被触发后，将利用PUSCH，一次性地反馈所有测量得到的CQI。SRS的周期型反馈的频率通过高层RRC进行配置。SRS的非周期型反馈通过接收DCI进行触发，每次触发后，UE在所配置子帧的最后一个符号上传输SRS，且只传输一次。
在未来演进的蜂窝网络系统中，对基站所获得的信道测量信息提出了很高要求，即对信道测量信息测量的频率要提高，因此使得CQI或SRS反馈间隔要缩短。然而，通过增加非周期反馈的次数或利用RRC配置动态改变反馈频率，会导致开销增大和配置响应不及时的问题，影响系统整体的频谱利用率。

下面将结合各个附图对本发明实施例技术方案的主要实现原理、具体实施方式及其对应能够达到的有益效果进行详细地阐述。
实施例一
本发明实施例一提出一种信道测量信息的反馈方法，如图1所示，其具体处理流程如下述：
101，UE确定用于周期性发送信道测量信息的上报周期的第一周期。
在上述101中，UE接收通过接收服务小区的系统信息，通过接收到的系统信息配置信道测量信息的上报周期的第一周期。第一周期的长短和生效时间(生效时间的配置可用通过对定时器的定时时间的配置)可以通过RRC信令配置实现。如图2所示的配置时序示意图，在对第一周期进行配置的具体流程为：UE接收LTE通信系统中基站发送的RRC信令。UE通过接收RRC Connection Setup获得RRC信令中的配置。该UE在获得RRC信令的配置后，UE确定第一周期。RRC信令的更改可以通过周期式和利用Paging触发式进行更改。每次更改都需要在第一个Modification Period上发送更改通知(Change notification)，之后再紧邻的下一个周期进行RRC配置的更新(Update)。
在LTE通信系统中，信道测量信息是CQI时，UE在确定CQI的第一周期时，UE通过接收高层信息RRC Connection Setup和RRC Connection Reconfiguration进行配置。UE接收到的高层信息内包含CQI-Report Config内 容，其中CQI-ReportPeriodic.cqi-pmi-ConfigIndex字段用于指示CQI的第一周期。具体地，以FDD通信系统为例，第一周期通过下述表1CQI周期反馈配置表获得。UE通过查询表1，在满足如下公式1的子帧上向基站反馈CQI。
Figure PCTCN2016105776-appb-000001
其中，在上述公式1中，nf用于表示无线帧的标号，ns表示无线帧内时隙的标号。第一周期反馈参数将会在接收到这个消息的无线帧内生效。
表1
Figure PCTCN2016105776-appb-000002
其中，在LTE通信系统中，信道测量信息是SRS时，UE在确定SRS的第一周期时，UE通过接收基站发送的SIB2、RRC Connection Setup、RRC Connection Reconfiguration进行配置。UE接收到的高层信息内包含soundingRS-UL-ConfigDedicated，其中srs-ConfigInde字段指示了上报SRS的第一周期。具体地以FDD系统为例，SRS的第一周期通过下述表2获得。UE通过查询表2，选择发送SRS的子帧满足下述公式2
(10·nf+kSRS-Toffset)modTSRS＝0
                                                  公式2
其中，上述公式2中，nf用于表示无线帧的标号，kSRS＝{0,1,…,9}。第一周期的参数将会在接收到这个消息时的无线帧内生效。
表2
Figure PCTCN2016105776-appb-000003
可选地，还包括：
101’，UE确定用于周期性发送信道测量信息的上报周期的第二周期。
本发明实施例一提出的技术方案中，UE在确定用于周期性发送信道测量信息的上报周期时，可以确定第二周期。
第二周期的配置信息中可以但不限于包含用于指示第一周期的指示信息、或者包含第一周期的配置信息。
其中，第二周期的配置信息包括下述中的至少一种信息：
第一种：第二周期的配置信息包含用于指示与第一周期之间的差值的信息。
第二种：第二周期的配置信息包含与第一周期相同的信息。
第三种：在第二周期的配置信息中，可以保留至少1位数值，至少1位数值用于指示发送周期为空(null)的情况。
发送周期为null时，即表示没有该周期。
102，基站向UE发送预先设定的DCI。
基站通过向UE发送预先设定的DCI，触发UE非周期性的上报信道测量信息。
103，UE接收基站发送的预先设定的DCI。
104，UE根据接收到基站发送的预先设定的DCI，UE以第一周期作为发送周期，周期性发送信道测量信息。
在上述实施例101-104中，UE根据接收到基站发送的预先设定的DCI，以第一周期作为发送周期，周期性发送信道测量信息，通过预先设定的DCI触发UE以第一周期作为发送周期，周期性发送信道测量信息。
相应地，UE在以第一周期作为发送周期，周期性发送信道测量信息之后，还可以停止以第一周期作为发送周期，周期性发送信道测量信息，具体实施方式为：
第一种实施方式：可以根据接收到的预先设定的DCI触发UE停止以第一周期作为发送周期，周期性发送信道测量信息。具体地，基站可以通过对DCI进行预先设定来实现。
上述第一种实施方式中，UE确定接收到的预先设定的DCI中的指示信息，在指示信息是用于开启所述第一周期的信息时，UE以第一周期作为发送周期，周期性发送信道测量信息，在指示信息是用于关闭第一周期的信息时，UE停止以第一周期作为发送周期，周期性发送信道测量信息。
第二种实施方式：通过设置与第一周期关联的第一计时器来实现。
上述第二种实施方式中，UE在以第一周期作为发送周期，周期性发送信道测量信息时，同时启动关联第一周期的第一计时器，在第一计时器计时到达时，UE停止以第一周期作为发送周期，周期性发送信道测量信息。
在上述实施例101-104中，UE以第一周期作为发送周期，周期性发送信道测量信息。进一步地，在101’中，UE确定了第二周期，则在104中，具体实施时：UE以第一周期和/或第二周期作为发送周期，周期性发送信道测量信 息。即UE若确定了第一周期和第二周期，则UE在接收到预先设定的DCI时，可以以第一周期作为发送周期，周期性发送信道测量信息。还可以以第二周期作为发送周期，周期性发送信道测量信息。进一步地，UE可以同时以第一周期和第二周期作为发送周期，周期性发送信道测量信息。
可选地，在上述103之前，还可以包括：
UE以第一周期作为发送周期,周期性发送信道测量信息，在UE接收到预先设定的DCI时，UE切换为以第二周期作为发送周期，周期性发送信道测量信息。
该种方式中，UE在未接收到基站发送的预先设定的DCI时，UE以第一周期作为发送周期发送信道测量信息，而当UE接收到基站发送的预先设定的DCI时，UE切换为以第二周期作为发送周期，周期性发送信道测量信息。即UE接收到预先设定的DCI是关闭第一周期，触发开启第二周期的一种实现方式。
进一步地，以第二周期发送的信道测量信息不同于第一周期发送的信道测量信息，且第二周期发送的信道测量信息的优先级大于以第一周期发送的信道测量信息的优先级，则若在同一时刻UE需要分别以第一周期和第二周期作为发送周期发送信道测量信息时，则在时刻UE切换以第二周期作为发送周期发送第二周期对应的信道测量信息。
举一例进行详细阐述：假设第一周期是3ms，第二周期是2ms从0ms开始计时，UE在2ms的倍数时发送一次信道测量信息，UE在3ms的倍数时发送一次信道测量信息，在第6ms时，UE需要以2ms的倍数发送信道测量信息，同时在第6ms时，UE还需要以3ms的倍数发送信道测量信息，该种情况下，以第二周期发送的信道测量信息的优先级大于以第一周期发送的信道测量信息的优先级，UE切换为以2ms的倍数发送信道测量信息。针对在第6ms时，UE需要以3ms的倍数发送信道测量信息的情况，UE可以停止以3ms的倍数发送信道测量信息，或者UE延时以3ms的倍数发送信道测量信息。
第二周期发送的信道测量信息的优先级大于以第一周期发送的信道测量 信息的优先级，该优先级在具体实施中，一种方式可以根据两个周期中发送的信道测量信息的准确度来确定，例如，第二周期中发送的信道测量信息的准确度大于第一周期中发送的信道测量信息的准确度。仍以上述第一周期是3ms，第二周期是2ms为例，在第6ms时，第二周期发送的信道测量信息的优先级大于以第一周期发送的信道测量信息的优先级，UE可以停止以3ms的倍数发送信道测量信息，这样可以上报较为准确的信道测量信息。该优先级在具体实施中，另一种方式可以根据信道测量信息的全面性来确定，例如信道测量信息是SRS信息时，反馈的SRS信息的带宽越宽，对应的发送该SRS信息的周期的优先级越高。
在上述方法流程中，UE以第一周期和/或第二周期作为发送周期，周期性发送信道测量信息，具体实施中，UE确定接收到的预先设定的DCI中的指示信息，其中指示信息用于对第一周期和/或第二周期进行指示；在指示信息是用于开启第一周期和/或第二周期的信息时，UE以第一周期和/或第二周期作为发送周期，周期性发送所述信道测量信息。
还可以包括：
在指示信息是用于关闭信道测量信息反馈，且UE以第二周期作为发送周期时，UE恢复为以第一周期作为发送周期，周期性发送信道测量信息。
还可以包括：
在指示信息是用于关闭信道测量信息反馈，且UE以第一周期作为发送周期时，UE停止以第一周期作为发送周期发送所述信道测量信息。
本发明实施例一上述提出的技术方案中，指示信息通过预先设定的DCI中的字段承载，预先设定的DCI中的字段包括下述中的至少一种：
A：DCI的下行分配索引DAI字段。
B：DCI Format 1a控制信令中的Resource block assignment字段；
若预先设定的DCI DCI Format 1a控制信令中的Resource block assignment字段，且Resource block assignment字段中的值为设定值时，获得DCI Format 1a控制信令中MCS字段中的指定位置信息，将指定位置信息作为指示信息。
C：DCI Format 0和/或所述DCI Format 4中的CSI Request及SRS Request字段。
若预先设定的DCI是DCI Format 0和/或DCI Format 4中的CSI Request及SRS Request字段时，UE触发一次非周期的信道测量信息；在发送非周期的信道测量信息后，UE以第一周期和/或第二周期作为发送周期，周期性地发送信道测量信息。在本发明实施例一上述提出的技术方案中，针对非周期的反馈信道测量信息的情况，可以通过高层信令配置周期反馈和非周期反馈的触发绑定，通过高层信令配置，UE在接收到非周期触发的指令时，可以按照非周期反馈的方式上报信道测量信息。若高层信令中未配置该种绑定方式，UE在接收到SCI/SRS Request后，不反馈周期信道测量信息。
本发明实施例一上述提出的技术方案中，通过RRC层的配置，配置多个不同信道测量信息的周期反馈参数，如，第一周期，第二周期等。进而定义LTE通信
系统中物理层下行传输控制信令，利用下行传输控制信令在物理层的传输，指示UE动态的切换信道测量信息的发送周期，从而可实现周期性反馈信道测量信息的开启、加速、减速、中断和关闭等功能，如图3所示。如果第二周期的反馈频率高于第一周期的频率，则呈现UE会加速反馈加速反馈信道测量信息的效果，反之如果第二周期的反馈频率低于第一周期的频率，则呈现UE减速反馈信道测量信息的反馈效果。当第二周期的周期定义为0，即不反馈信息，则通实现了周期反馈的中断效果。如果当前第二周期穿插在第一周期中的周期反馈间隔内，则呈现出开启、停止等效果，从而实现能够降低指示周期反馈的同时，减低减小系统开销，提高配置响应，提升系统的频谱利用率。
实施例二
本发明实施例二提出的技术方案中，以信道测量信息是CQI或SRS为例，进一步阐述信道测量信息的反馈方法，如图4所示，该方法具体处理流程如下述：

本发明实施二提出的技术方案中，以UE通过接收基站发送的系统信息配置第二计时器，该第二计时器与第二周期相关联为例进行详细阐述。具体地，针对和第一周期关联的第一定时器的实现方式，与第二周期关联的第二计时器的实现方式相同，不再赘述。
当UE以第二周期作为发送周期，周期性向基站反馈CQI/SRS时，该关联的第二计时器开启，开始计时，直到该第二计时器计时结束为止，在此期间，任何对该第二计时器的触发都无法关闭或重启该计时器。
403，基站向UE发送预先设定的DCI。

407，UE切换为以第二周期作为发送周期，周期性发送CQI/SRS，并开启和第二周期关联的第二计时器。
408，第二计时器超时结束计时时，UE切换为以第一周期作为发送周期，周期性发送CQI/SRS。
409，UE继续保持当前发送周期，周期性发送CQI/SRS。
上述方法流程中，以第二周期关联的第二计时器为例进行详细阐述，在具体实施中，针对和第一周期关联的第一定时器，具体实施中，UE以第一周期作为发送周期，周期性发送信道测量信息，包括：UE开启第一计时器，以及在第一计时器计时到达时，UE停止以第一周期作为发送周期，周期性发送信道测量信息。
本发明实施例二上述提出的技术方案中，通过设置第一周期、第二周期，以及和第一周期关联的第一计时器，第二周期关联的第二计时器，使得UE在切换为以第二周期作为发送周期，发送CQI/SRS时，直至与第二周期关联的第二计时器结束计时，自动切换为以第一周期作为发送周期，发送CQI/SRS，实现了对短周期反馈CQI/SRS的触发。
在本发明实施例二上述提出的技术方案中，UE以第一周期作为发送周期发送CQI/SRS的具体实施方式与以第二周期作为发送周期发送CQI/SRS的具体实施方式相同地方不再赘述，仅以触发UE以第二周期作为发送周期发送CQI/SRS为例进行阐述。
实施例三
本发明实施例三提出的技术方案中，以信道测量信息是CQI或SRS为例，进一步阐述信道测量信息的反馈方法，如图5所示，该方法具体处理流程如下述：
501，UE确定用于周期性发送CQI/SRS的上报周期的第一周期，和第二周期。

基站通过向UE发送预先设定的DCI，触发UE非周期发送CQI/SRS。
以预先设定的DCI可以是DCI的下行分配索引(Downlink Assignment Index，DAI)字段为例进行详细阐述，基站可以通过下行非公共参考信令DCI的下行分配索引字段，对UE以第二周期作为发送周期，周期性发送CQI/SRS 进行指示。
在标准中规定，DCI的DAI位置用于指示捆绑反馈肯定应答/否定应答(ACK/NACK)信息，则本步骤在具体实施时，基站可以在DCI的DAI位置，不使用ACK/NACK时，承载用于对第二周期进行指示的指示信息。
例如，可以取出DAI字段内的1bit位信息作为开启或关闭UE以第二周期作为发送周期，周期性发送CQI/SRS的指示信令，具体如下述表3所示的一种DAI字段指示信令示意。
表3
DAI字段信息 状态
0 开启

503，UE接收基站发送的预先设定的DCI。
504，UE确定DCI中承载的是否是开启或关闭UE以第二周期作为发送周期，周期性发送CQI/SRS的指示信息，如果判断结果为是，执行505，反之不处理。
UE接收基站发送的DCI，UE在接收到的DCI中，如果检测到当前不使用捆绑ACK/NACK时，则确定DCI中的DAI字段承载的是开启或关闭UE以第二周期作为发送周期，周期性发送CQI/SRS的指示信令。

507，若UE没有将第一周期作为发送周期，则UE继续保持当前发送周期，周期性发送CQI/SRS。
在上述505～507中，UE在下行控制信道接收到的DCI中，如果检测当前不使用捆绑反馈ACK/NACK，则说明当前DAI中承载的是周期发送CQI/SRS 触发指令。此时，如果检测到DAI字段信息，如果接收为0，则停止以第一周期作为发送周期向基站发送CQI/SRS，切换为以第二周期作为发送周期，向基站发送CQI/SRS。如果接收为1，则停止当前的以第二周期作为发送周期向基站周期性发送CQI/SRS，恢复为以第一周期作为发送周期，周期性地向基站发送CQI/SRS。
上述实施例三提出的技术方案中，通过对DCI的DAI字段中承载的信息进行定义，指示UE动态的切换信道测量信息的发送周期。
实施例四

604，UE确定DCI中承载的是否是开启或关闭UE以第二周期作为发送周期，周期性发送CQI/SRS的指示信令，如果判断结果为是，执行605，反之不处理。
例如，UE在下行控制信道接收到的DCI Format 1a中，如果检测到Resource block assignment字段信息为全0，则确定是开启或关闭UE以第二周期作为发送周期，周期性发送CQI/SRS的指示信令。
其中，Resource block assignment字段信息还可以是全部为1，用于作为开启或关闭UE以第二周期作为发送周期，周期性发送CQI/SRS的指示信令。
605，UE继续检测DCI Format 1a中MCS字段中的第一位信息。
606，如果MCS字段中的第一位信息接收为0，则停止以第一周期作为发送周期，UE切换为以第二周期作为发送周期，周期性发送CQI/SRS。
607，如果MCS字段中的第一位信息接收为1，则停止以第二周期作为发送周期，UE切换为以第一周期作为发送周期，周期性发送CQI/SRS。
