Description

一种非周期CSI的传输方法和设备
本申请要求在2015年9月25日提交中国专利局、申请号为201510624883.8、发明名称为“一种非周期CSI的传输方法和设备”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
本发明涉及通信技术领域，特别涉及一种非周期信道状态信息(CSI，Channel State Information)的传输方法和设备。
背景技术
在长期演进增强(LTE-A，Long Term Evolution-Advanced)版本(Release，简称Rel)-10载波聚合(CA，Carrier Aggregation)系统中，支持最大5个载波聚合。为了实现对不同载波的非周期信道状态信息(A-CSI，Aperiodic Channel State Information)上报，在下行控制信息(DCI，Downlink Control Information)中定义了最大2比特的A-CSI触发比特，用于按照表1-1实现对不同载波组合的A-CSI的触发，其中第一载波集合(set)和第二载波集合为高层信令预先配置的两个载波集合，不同的组合情况可以覆盖最大5个载波的A-CSI触发和上报。当一个载波上存在超过一个CSI进程时，每个CSI进程的A-CSI是要独立上报的，因此，还存在如表1-2所示的指示对应关系。
表1-1：在用户设备(User Equipment，UE)专用搜索空间中传输的、携带上行DCI格式的物理下行控制信道(Physical Downlink Control Channel，PDCCH)中的CSI请求指示域(CSI Request field for PDCCH with uplink DCI format in UE specific search space)

Figure PCTCN2016093633-appb-000002
Figure PCTCN2016093633-appb-000003
在LTE-A Rel-13 CA系统中，支持最多32载波聚合。随着聚合载波数量的增加，需要进行A-CSI上报的载波数量也随之增加。原DCI中的2比特的A-CSI触发比特已经不足以支持最大32个载波的A-CSI触发了。需要扩展A-CSI触发比特，以支持定义更多的进行A-CSI上报的载波集合。目前，已经定义了在DCI中使用3比特的A-CSI触发比特来触发不同的A-CSI上报集合。考虑到用户设备的处理能力有限，在一个子帧中最大可以处理不超过5个CSI进程，一个载波对应至少一个CSI进程。当假设一个载波对应一个CSI进程时，一次A-CSI触发最多只能触发5个载波进行A-CSI上报，如果一个载波对应多于一个CSI进程，则一次A-CSI触发所能触发的载波数更少。对于32个载波，当假设一个载波对应一个CSI进程时，需要分为至少7个载波集合分别进行A-CSI上报，才能覆盖所有载波的A-CSI上报，此时载波集合等同于CSI进程集合，当假设一个载波对应多于一个CSI进程时，需要分为超过7个CSI进程集合或载波集合分别进行A-CSI上报，才能覆盖所有载波的A-CSI上报。3比特的A-CSI触发比特一共可以指示23＝8个不同状态，其中，至少需要其中一个状态用于指示不进行A-CSI上报，还需要一个状态用于指示进行本载波的A-CSI上报，剩余的6个状态不足以指示至少7个不同的上报集合。目前，如何使用3比特的A-CSI触发比特指示32个载波聚合情况下的A-CSI上报还没有明确方法。

具体实施方式
本发明实施例通过配置不同的下行子帧对应的非周期CSI上报集合，或者不同的上行子帧对应的非周期CSI上报集合，实现了通过较少的非周期CSI触发比特，指示较多聚合载波情况下的不同非周期CSI上报集合的A-CSI上报。
下面结合说明书附图对本发明实施例作进一步详细描述。应当理解，此处所描述的实施例仅用于说明和解释本发明，并不用于限定本发明。
本发明实施例提供的用户设备侧的一种非周期CSI的发送方法，如图1所示，该方法包括：
S11、用户设备获取非周期CSI请求指示域；
S12、若该非周期CSI请求指示域指示所述用户设备需要进行非周期CSI上报，所述用户设备根据所述非周期CSI请求指示域的指示状态，从接收到所述非周期CSI请求指示域的下行子帧对应的非周期CSI上报集合、或者携带所述非周期CSI请求指示域的调度信息所调度的上行子帧对应的非周期CSI上报集合中，确定出需要进行非周期CSI上报的非 周期CSI上报集合；
S13、所述用户设备发送所述需要进行非周期CSI上报的非周期CSI上报集合对应的非周期CSI。
本发明实施例中，用户设备获取非周期CSI请求指示域；若该非周期CSI请求指示域指示所述用户设备需要进行非周期CSI上报，所述用户设备根据所述非周期CSI请求指示域的指示状态，从接收到所述非周期CSI请求指示域的下行子帧对应的非周期CSI上报集合、或者携带所述非周期CSI请求指示域的调度信息所调度的上行子帧对应的非周期CSI上报集合中，确定出需要进行非周期CSI上报的非周期CSI上报集合；所述用户设备发送所述需要进行非周期CSI上报的非周期CSI上报集合对应的非周期CSI，从而通过配置不同的下行子帧对应的非周期CSI上报集合，或者不同的上行子帧对应的非周期CSI上报集合，实现了通过较少的非周期CSI触发比特，指示较多聚合载波情况下的不同非周期CSI上报集合的A-CSI上报。
可选的，所述非周期CSI上报集合具体为：CSI进程和CSI子帧集合对形成的集合、载波集合、CSI进程集合中的一种或多种的组合。
举例说明，CSI进程和CSI子帧集合对形成的集合可以表示为{CSI进程，CSI子帧集合}对的集合，其中CSI子帧集合是用于进行CSI测量的子帧，具体内容不再赘述。例如，{CSI进程，CSI子帧集合}对的集合中包含的元素为：{CSI进程1，CSI子帧集合1}对、{CSI进程2，CSI子帧集合2}、{CSI进程3，CSI子帧集合3}等。
需要说明的是，载波集合也可以理解为服务小区集合，每个服务小区包含至少一个上行载波和/或至少一个下行载波，服务小区中的上行传输通过其包含的至少一个上行载波实现，服务小区中的下行传输通过其包含的至少一个下行载波实现，由于A-CSI是基于下行载波上的相关参考信号测量得到的，因此A-CSI对应的是下行载波的A-CSI。
可选的，所述非周期CSI请求指示域携带在DCI或者随机接入响应许可(grant)中。
本发明实施例中，对于聚合了多个载波的用户设备，在触发非周期CSI上报时，包括以下两种可选的实现方式：
方式一、所触发的进行非周期CSI上报的非周期CSI上报集合与包含非周期CSI请求指示域的DCI或随机接入响应许可(grant)传输所在的下行子帧相关，即配置了不同下行子帧对应的非周期CSI上报集合，用户设备可以根据接收到非周期CSI请求指示域的下行子帧，确定出需要进行非周期CSI上报的非周期CSI上报集合。
该方式下，所述下行子帧所对应的非周期CSI上报集合为高层信令预先配置的非周期CSI上报集合。
该方式下，所述下行子帧对应至少一个所述非周期CSI上报集合，且不同的下行子帧所对应的非周期CSI上报集合部分相同或完全不同。
该方式下，所述非周期CSI请求指示域的指示状态与所述下行子帧对应的非周期CSI上报集合的对应关系为预先约定或者由高层信令预先配置。
举例说明，对于任一下行子帧来说，所述非周期CSI请求指示域的值为“000”时，其指示状态为无非周期CSI上报；所述非周期CSI请求指示域的值为“001”时，其指示状态为触发被调度载波的非周期CSI上报；所述非周期CSI请求指示域的值为“010”、“011”、“100”、“101”、“110”和“111”时，其指示状态分别为触发高层信令预先配置的不同非周期CSI上报集合的非周期CSI上报。
需要说明的是，如果存在多个下行子帧，每个下行子帧对应的非周期CSI上报集合可以完全不同，例如，假设定义了12个非周期CSI上报集合，下行子帧1对应触发非周期CSI上报集合1～6的非周期CSI上报，下行子帧2对应触发非周期CSI上报集合7～12的非周期CSI上报；或者不同下行子帧所对应的非周期CSI上报集合部分相同，例如，假设定义了8个非周期CSI上报集合，下行子帧1对应触发非周期CSI上报集合1～6的非周期CSI上报，下行子帧2对应触发非周期CSI上报集合1～4和非周期CSI上报集合7～8的非周期CSI上报。
如果一个无线帧中存在N个下行子帧，对N1个下行子帧独立定义的非周期CSI上报集合就可以实现对所有非周期CSI上报集合的分别指示，那么剩余N-N1个下行子帧所对应的非周期CSI上报集合可以同N1个下行子帧中的任意一个子帧所对应的非周期CSI上报集合。例如，一个无线帧中可用的下行子帧有10个，则可以对下行子帧1、3、5、7、9都定义同下行子帧1的对应关系，即对应触发非周期CSI上报集合1～6的非周期CSI上报，对下行子帧2、4、6、8、10都定义同下行子帧2的对应关系，即对应触发非周期CSI上报集合7～12的非周期CSI上报，此时，如果基站想触发非周期CSI上报集合1～6中的任意一个非周期CSI上报集合的非周期CSI上报时，可以产生相应的非周期CSI请求指示域，并在下行子帧1、3、5、7、9中的任意一个下行子帧中发送携带该非周期CSI请求指示域的DCI或随机接入响应grant即可。相应的，用户设备在下行子帧1、3、5、7、9中的任意一个下行子帧中检测到的非周期CSI请求指示域，确定所触发的非周期CSI上报集合。
方式二、所触发的进行非周期CSI上报的非周期CSI上报集合与包含该非周期CSI请求指示域的DCI或随机接入响应grant所调度的上行子帧相关，即配置了不同上行子帧对应的非周期CSI上报集合，用户设备可以根据接收到非周期CSI请求指示域的下行子帧所调度的上行子帧，确定出需要进行非周期CSI上报的非周期CSI上报集合。
该方式下，所述上行子帧所对应的非周期CSI上报集合为高层信令预先配置的非周期CSI上报集合。
该方式下，所述上行子帧对应至少一个所述非周期CSI上报集合，且不同的上行子帧所对应的非周期CSI上报集合部分相同或完全不同。
该方式下，所述非周期CSI请求指示域的指示状态与所述上行子帧对应的非周期CSI上报集合的对应关系为预先约定或者由高层信令预先配置。
举例说明，对于任一上行子帧来说，所述非周期CSI请求指示域的值为“000”时，其指示状态为无非周期CSI上报；所述非周期CSI请求指示域的值为“001”时，其指示状态为触发被调度载波的非周期CSI上报；所述非周期CSI请求指示域的值为“010”、“011”、“100”、“101”、“110”和“111”时，其指示状态分别为触发高层信令预先配置的不同非周期CSI上报集合的非周期CSI上报。
该方式下，可选的，高层信令预先配置用于调度上行子帧的下行子帧对应的非周期CSI上报集合。也就是说，所述上行子帧配置了对应的非周期CSI上报集合，用于调度所述上行子帧的下行子帧也配置了对应的非周期CSI上报集合。
该可选的方式中，用户设备需要知道采用哪种对应关系。具体实现包括：通过高层信令通知用户设备确定需要进行非周期CSI上报的非周期CSI上报集合时采用的子帧与非周期CSI上报集合的对应关系，或者预先约定用户设备确定需要进行非周期CSI上报的非周期CSI上报集合时采用的子帧与非周期CSI上报集合的对应关系。
该对应关系包括调度所述上行子帧的下行子帧与非周期CSI上报集合的对应关系(即调度所述上行子帧的下行子帧对应的非周期CSI上报集合)，以及所述上行子帧与非周期CSI上报集合的对应关系(即使是上行子帧对应的非周期CSI上报集合)。
该可选的方式中，调度所述上行子帧的下行子帧对应至少一个所述非周期CSI上报集合，且不同的下行子帧所对应的非周期CSI上报集合部分相同或完全不同。
该可选的方式中，所述非周期CSI请求指示域的指示状态与调度所述上行子帧的下行子帧对应的非周期CSI上报集合的对应关系为预先约定或者由高层信令预先配置。
基于同一发明构思，本发明实施例还提供了一种基站侧的非周期CSI的接收方法，如图2所示，所述方法包括：
S21、基站确定出需要进行非周期CSI上报的非周期CSI上报集合；
S22、所述基站生成所述需要进行非周期CSI上报的非周期CSI上报集合对应的非周期CSI请求指示域；
S23、所述基站在与所述需要进行非周期CSI上报的非周期CSI上报集合对应的下行子帧、或者用于调度与所述需要进行非周期CSI上报的非周期CSI上报集合对应的上行子帧的下行子帧中发送所述非周期CSI请求指示域；
S24、所述基站接收所述需要进行非周期CSI上报的非周期CSI上报集合的非周期CSI。
本发明实施例中，基站确定出需要进行非周期CSI上报的非周期CSI上报集合；生成所述需要进行非周期CSI上报的非周期CSI上报集合对应的非周期CSI请求指示域；在与所述需要进行非周期CSI上报的非周期CSI上报集合对应的下行子帧、或者用于调度与所 述需要进行非周期CSI上报的非周期CSI上报集合对应的上行子帧的下行子帧中发送所述非周期CSI请求指示域；接收所述需要进行非周期CSI上报的非周期CSI上报集合的非周期CSI，从而通过配置不同的下行子帧对应的非周期CSI上报集合，或者不同的上行子帧对应的非周期CSI上报集合，实现了通过较少的非周期CSI触发比特，指示较多聚合载波情况下的不同非周期CSI上报集合的A-CSI上报。
可选的，所述非周期CSI上报集合具体为：CSI进程和CSI子帧集合对形成的集合、载波集合、CSI进程集合中的一种或多种的组合。
可选的，所述非周期CSI请求指示域携带在下行控制信息DCI或者随机接入响应许可grant中。
可选的，所述下行子帧所对应的非周期CSI上报集合为高层信令预先配置的非周期CSI上报集合，具体参见上述方式一的描述；或者
所述上行子帧所对应的非周期CSI上报集合为高层信令预先配置的非周期CSI上报集合，具体参见上述方式二的描述。
基于上述任一实施例，所述下行子帧对应至少一个所述非周期CSI上报集合，且不同的下行子帧所对应的非周期CSI上报集合部分相同或完全不同；或者
所述上行子帧对应至少一个所述非周期CSI上报集合，且不同的上行子帧所对应的非周期CSI上报集合部分相同或完全不同。
基于上述任一实施例，所述非周期CSI请求指示域的指示状态与所述下行子帧对应的非周期CSI上报集合的对应关系为预先约定或者由高层信令预先配置；或者，
所述非周期CSI请求指示域的指示状态与所述上行子帧对应的非周期CSI上报集合的对应关系为预先约定或者由高层信令预先配置。
需要说明的是，所述下行子帧可以是所述需要进行非周期CSI上报的非周期CSI上报集合对应的下行子帧，也可以是用于调度与所述需要进行非周期CSI上报的非周期CSI上报集合对应的上行子帧的下行子帧。具体参见用户设备侧的描述，此处不再赘述。
下面通过两个具体实施例，以非周期CSI上报集合为载波集合为例对本发明实施例提供的一种非周期CSI的传输方法进行详细说明，非周期CSI上报集合为其他形式的情况与此类似，此处不再一一举例说明。
实施例1：假设高层信令预先对下行子帧1配置如表2所示的非周期CSI(以下简称A-CSI)上报对应关系，对下行子帧2配置如表3所示的A-CSI上报对应关系。其中，载波集合1～12中的每个载波集合所包含的载波可以完全不同，或者部分相同。例如，用户设备聚合了载波1～32共32个载波，可以将载波1～24中每3个载波定义为一个载波集合，例如载波1～3定义为载波集合1，载波4～6定义为载波集合2，以此类推，载波22～24定义为载波集合8，将载波25～32中每2个载波定义为一个载波集合，例如载波25和26定 义为载波集合9，载波27和28定义为载波集合10，以此类推，载波31和32定义为载波集合12；或者也可以存在部分重叠，例如载波1～4定义为一个载波集合，载波3～5定义为一个载波集合；当然本发明实施例也不排除其他定义方式，只要能覆盖32个载波分布在12个载波集合中即可；
基站侧：当确定需要触发载波集合3进行A-CSI上报时，确定载波集合3所对应的3比特A-CSI请求指示域的具体比特为“100”，并且在下行子帧1中发送携带该A-CSI请求指示域的DCI或随机接入响应grant；
当确定需要触发载波集合9进行A-CSI上报时，确定载波集合9所对应的3比特A-CSI请求指示域的具体比特为“100”，并且在下行子帧2中发送携带该A-CSI请求指示域的DCI或随机接入响应grant。
用户设备侧：在每个下行子帧中检测下行传输，当在下行子帧1中接收到携带A-CSI请求指示域的DCI或随机接入响应grant时，解析得到A-CSI请求指示域的具体比特“100”，将该“100”与下行子帧1所对应的映射表(即表2)相对应，确定该A-CSI请求指示域所触发的是载波集合3的A-CSI上报；在该下行子帧所调度的上行子帧的物理上行共享信道(Physical Uplink Shared Channel，PUSCH)中反馈载波集合3的A-CSI；
当在下行子帧2中接收到携带A-CSI请求指示域的DCI或随机接入响应时，解析得到A-CSI请求指示域的具体比特“100”，将该“100”与下行子帧2所对应的映射表(即表3)相对应，确定该A-CSI请求指示域所触发的是载波集合9的A-CSI上报；在该下行子帧所调度的上行子帧的PUSCH中反馈载波集合9的A-CSI。
需要说明的是，如果存在多个下行子帧，每个下行子帧对应的载波集合可以完全不同，如表2和表3所示，或者不同下行子帧所对应的载波集合部分相同，例如，对该实施例，仅定义8个载波集合，则可以按照表2和表4方式定义映射关系。
另外，如果一个无线帧中存在N个下行子帧，对N1个下行子帧独立定义载波集合就可以实现对所有载波集合的分别指示，那么剩余N-N1个下行子帧所对应的载波集合可以同N1个下行子帧中的任意一个子帧所对应的载波集合。例如，一个无线帧中可用的下行子帧有10个，则可以对下行子帧1、3、5、7、9都定义同下行子帧1的对应关系，对下行子帧2、4、6、8、10都定义同下行子帧2的对应关系，此时，例如，当基站想触发载波集合1～6中的任意一个载波集合的A-CSI时，可以产生相应的A-CSI请求指示域，并在下行子帧1、3、5、7、9中的任意一个下行子帧发送携带该A-CSI请求指示域的DCI或随机接入响应grant，相应的用户设备在下行子帧1、3、5、7、9中的任意一个下行子帧中检测到的A-CSI请求指示域，都对应表2确定所触发的载波集合。

表3：子帧2中A-CSI请求指示域与触发内容的对应关系

表4：子帧2中A-CSI请求指示域与触发内容的对应关系
Figure PCTCN2016093633-appb-000006
实施例2：高层信令预先对上行子帧1配置如表2所示的A-CSI上报对应关系，对上行子帧2配置如表3所示的A-CSI上报对应关系；其中载波集合1～12的具体划分方式与实施例类似。
基站侧：当确定需要触发载波集合4进行A-CSI上报时，确定载波集合4所对应的3比特A-CSI请求指示域的具体比特为“101”，并且在调度该上行子帧1的下行子帧中发送携带该A-CSI请求指示域的DCI或随机接入响应grant；
当确定需要触发载波集合11进行A-CSI上报时，确定载波集合11所对应的3比特A-CSI请求指示域的具体比特为“110”，并且在调度该上行子帧2的下行子帧中发送携带该A-CSI请求指示域的DCI或随机接入响应grant.
用户设备侧：在每个下行子帧中检测下行传输，当在调度上行子帧1的下行子帧中接收到携带A-CSI请求指示域的DCI或随机接入响应grant时，解析得到A-CSI请求指示域的具体比特为“101”，将该“101”与上行子帧1所对应的映射表(即表2)相对应，确定该A-CSI请求指示域所触发的是载波集合4的A-CSI上报；在国上行子帧1的PUSCH中反馈载波集合4的A-CSI；
当在调度上行子帧2的下行子帧中接收到携带A-CSI请求指示域的DCI或随机接入响 应grant时，解析得到A-CSI请求指示域的具体比特为“110”，将该“110”与上行子帧2所对应的映射表(即表3)相对应，确定该A-CSI请求指示域所触发的是载波集合11的A-CSI上报；在该上行子帧2的PUSCH中反馈载波集合11的A-CSI。
需要说明的是，如果存在多个上行子帧，每个上行子帧对应的载波集合可以完全不同，例如表2和表3所示，或者不同上行子帧所对应的载波集合部分相同，例如，对该实施例，仅定义8个载波集合，则可以按照表2和表4方式定义映射关系。
另外，如果一个无线帧中存在N个上行子帧，对N1个上行子帧独立定义载波集合就可以实现对所有载波集合的分别指示，那么剩余N-N1个上行子帧所对应的载波集合可以同N1个上行子帧中的任意一个子帧所对应的载波集合。例如，一个无线帧中可用的上行子帧有10个，则可以对上行子帧1、3、5、7、9都定义同上行子帧1的对应关系，对上行子帧2、4、6、8、10都定义同上行子帧2的对应关系，此时，例如，当基站想触发载波集合1～6中的任意一个载波集合的A-CS上报I时，可以产生相应的A-CSI请求指示域，并在调度上行子帧1、3、5、7、9的下行子帧中的任意一个下行子帧发送携带该A-CSI请求指示域的DCI或随机接入响应grant；相应的，用户设备在调度上行子帧1、3、5、7、9的下行子帧中的任意一个下行子帧中检测到的A-CSI请求指示域，都对应表2确定触发的载波集合。
上述实施例中，不同子帧中定义的A-CSI请求指示域与所指示内容的对应表格中，可以仅包括一个载波集合，即每个子帧仅对应一个触发集合，可以不包括触发服务小区c(具体解释同上，也可称为载波c)的A-CSI上报的状态，即将服务小区c直接配置在某个集合中；另外，上述实施例中的载波和载波集合还可以替换为CSI进程和CSI进程集合，或者替换为CSI进程集合和/或{CSI进程,CSI子帧集合}对的集合，其中CSI子帧集合是用于进行CSI测量的子帧，具体内容不再赘述。
上述方法处理流程可以用软件程序实现，该软件程序可以存储在存储介质中，当存储的软件程序被调用时，执行上述方法步骤。
