Description

信道状态信息的优先级发送、确定方法及装置、存储介质、用户设备
本申请要求2019年9月26日提交中国专利局、申请号为2019109188894、发明名称为“信道状态信息的优先级发送、确定方法及装置、存储介质、用户设备”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，尤其涉及一种信道状态信息的优先级发送、确定方法及装置、存储介质、用户设备。
背景技术
车联网(Vehicle-to-Everything，V2X)是未来智能交通运输系统的关键技术，主要研究基于第三代合作伙伴计划(3rd Generation Partnership Project,3GPP)通信协议的车辆数据传输方案。V2X通信包括车与车通信(Vehicle to Vehicle,V2V)、车与路侧基础设施通信(Vehicle to Infrastructure,V2I)以及车与行人通信(Vehicle to People,V2P)。V2X应用将改善驾驶安全性、减少拥堵和车辆能耗、提高交通效率和车载娱乐信息等。
在V2X通信中，V2V通信是一种和普通无线蜂窝网络通信不同的通信方式，在传统的蜂窝网络中，用户设备和基站设备进行通信，而在V2V通信中，用户设备直接和用户设备进行通信，用户设备和用户设备之间的链路称为直连链路(SideLink，SL)。虽然直连链路是用户设备和用户设备之间的直接通信，直连链路上的传输仍然全部或部分受基站设备的控制。也即，有部分控制信息仍然需要在基站和用户设备之间传输。在4G长期演进(Long Term Evolution，LTE)通信系统中，V2X sidelink通信是以广播通信为基础的，采用的是“一对所有”的通信模式。5G新无线(New Radio，NR)通信系统中，引入 了单播的V2X通信，采用“一对一”的通信模式。这种情况下，为了提高发送设备的传输效率，接收设备可以向发送设备反馈信道状态信息(Channel State Information，CSI)，以协助发送设备根据自己和接收设备之间的信道状况，调整发送参数。CSI可以通过媒体接入控制(Media Access Control，MAC)层的控制单元(Control Element，CE)携带，最终的结果称为CSI MAC CE。CSI还可以直接通过物理层控制信令去携带。
通常来说，一个发送设备可能存在多种业务的数据需要传输，当发送设备获得一块传输资源后，下一步就是要考虑将这些属于不同业务的数据放到这块资源上，这个过程在3GPP协议中称为逻辑信道优先级过程(logical channel prioritization,LCP)。在V2X sidelink中，不同业务是通过不同的逻辑信道(logical channel)、源地址(source address)和目标地址(destination address)来体现的。同一组源地址和目标地址的组合下可能有多个逻辑信道，每个逻辑信道有一个优先级，LCP过程的本质就是根据逻辑信道的优先级，按照一定规则将逻辑信道承载的业务的数据放到一块传输资源上。在LTE系统中，V2X的LCP过程可以简单描述如下：
Step 0：首先完成逻辑信道筛选，根据传输资源的参数和逻辑信道的配置和参数，筛选出参与LCP过程的逻辑信道。例如在V2X中，一个逻辑信道可能只能在某些载波上传输，如果当前传输资源位于的载波不是该逻辑信道允许传输的载波，该逻辑信道就被排除在这次LCP流程之外；Step 1：从有待传输数据的逻辑信道中，选择优先级最高的逻辑信道对应的源地址和/或目标地址；Step 2：为Step 1确定的源地址和/或目标地址里优先级最高的有待传输数据的逻辑信道分配传输资源；Step 3：如果还有剩余资源，那么按照优先级从高到低，为该目标地址下的逻辑信道分配传输资源，直到传输资源耗尽，或者逻辑信道的数据耗尽。
另外，在直连链路上，还存在感知(sensing)过程，当发送用户 设备有待传输数据要发送时，如果发送资源不是由基站分配的，发送用户设备需要执行感知过程，从而进行发送资源的抢占和预留，感知过程同样需要考虑到待传输数据的优先级，不同的优先级的数据，允许抢占的资源大小、占用的资源比率、传输功率等参数都可以是不同的，例如对于高优先级的数据，在一定情况下，允许在已经被低优先级占用的资源上传输。
但是，目前V2X LCP过程和sensing过程中，都没有考虑CSI反馈引入之后如何确定信道状态信息的优先级问题。

具体实施方式
如背景技术中所述，目前V2X LCP和sensing过程，没有考虑CSI反馈引入之后如何确定信道状态信息的优先级问题。
本发明技术方案中，由于CSI通常与发送用户设备要发送的业务数据有关，而只有发送用户设备和/或基站才拥有要发送的业务数据特征信息，因此信道状态信息的优先级可以由发送用户设备或者基站指示给接收用户设备，也即可以由发送用户设备或者基站通过控制信息来进行指示，以使得接收用户设备能够通过控制信息来确定信道状态信息的优先级，实现了信道状态信息的优先级确定的便捷性。
本方明技术方案可适用于5G(5 Generation)通信系统，还可适用于4G、3G通信系统，还可适用于未来新的各种通信系统，例如6G、7G等。
为使本发明的上述目的、特征和优点能够更为明显易懂，下面结合附图对本发明的具体实施例做详细的说明。
图1是本发明实施例一种信道状态信息的优先级发送方法的流程图。
信道状态信息的优先级发送方法可以用于发送用户设备侧，发送用户设备是指发送V2X数据的用户设备；也即可以由发送用户设备执行图1所示的各个步骤。信道状态信息的优先级发送方法也可以用于基站侧；也即可以由基站执行图1所述的各个步骤。
图1所示信道状态信息的优先级发送方法可以包括以下步骤：
步骤S101：确定信道状态信息的优先级信息；
步骤S102：发送控制信息，所述控制信息包括信道状态信息的优先级信息。
需要指出的是，本实施例中各个步骤的序号并不代表对各个步骤的执行顺序的限定。
在步骤S101的具体实施中，发送用户设备可以先确定信道状态信息(Channel State Information，CSI)的优先级信息。所述优先级信息能够指示CSI的优先级。具体地，CSI的优先级信息可以直接地指示CSI的优先级，或者间接地指示CSI的优先级。例如，优先级信息可以包括CSI的优先级，或者CSI的优先级的计算方式。
在CSI的优先级信息直接地指示CSI的优先级时，接收用户设备可以直接根据CSI的优先级信息确定CSI的优先级。在CSI的优先级信息间接地指示CSI的优先级时，接收用户设备需要根据CSI的优先级信息中CSI的优先级的计算方式来计算获得CSI的优先级。
具体地，在CSI通过媒体接入控制(Media Access Control，MAC)层的控制单元(Control Element，CE)携带时，所述CSI的优先级可以是CSI MAC CE的优先级。在CSI直接通过物理层控制信令携带时，所述CSI的优先级是携带CSI的物理资源块的优先级。CSI也可以通过其他任意可实施的控制信令来承载，本发明实施例对此不作限制。
需要说明的是，CSI的优先级可以用于在LCP过程中为CSI分配传输资源。具体地，可以根据CSI的优先级与各个逻辑信道的优先级执行逻辑信道优先级过程，以为各个逻辑信道和CSI MAC CE分配传输资源。CSI的优先级也可以用于在sensing过程中为CSI的传输抢占传输资源，可以根据CSI的优先级与待传输数据对应的逻辑信道的优先级执行sensing过程。CSI的优先级还可以用于任何需要考虑传输数据或控制信令特性的过程中，本发明实施例对此不作限制。
进而在步骤S102的具体实施中，发送用户设备可以将CSI的优先级信息携带于控制信息中发送出去。具体地，所述控制信息可以是高层信令，也可以是物理层信令。
在一个具体实施例中，图1所示步骤S102可以包括以下步骤：发送触发CSI上报的控制信息。
本实施例中，所述控制信息是用于触发CSI上报的控制信息。也就是说，通过复用触发CSI上报的控制信息来承载CSI的优先级信息，可以节省用户设备的信令开销。
具体地，触发CSI上报的控制信息可以是物理层信令。
具体地，触发CSI上报的控制信息可以通过显式或隐式的方式触发CSI的上报。当通过显示方式触发CSI上报时，可以设计专门的物理层信令，用于触发CSI上报，或者，在现有物理层信令中加入指示域，所述指示域指示是否需要CSI上报。当通过隐式方式触发CSI上报时，可以通过物理层信令是否调度了用于测量CSI的参考信号来确定是否触发CSI上报。本发明实施例对具体的CSI触发的方式不作限制。
需要说明的是，触发CSI上报的控制信息也可以同时有其他的作用，例如，触发CSI上报的控制信息也可以同时用于调度数据传输，由于直连链路下的数据调度的控制信息也会携带实际发送数据的优先级，因此，此时，触发CSI上报的控制信息中承载的CSI的优先级 信息，可以复用控制信息中携带的发送数据的优先级。
本发明实施例中，由于CSI通常与发送用户设备要发送的业务数据有关，而只有发送用户设备和/或基站才拥有要发送的业务数据特征信息，因此信道状态信息的优先级可以由发送用户设备或者基站指示给接收用户设备，也即可以由发送用户设备或者基站通过控制信息来进行指示，以使得接收用户设备能够通过控制信息来确定信道状态信息的优先级，实现了信道状态信息的优先级确定的便捷性。
本发明一个非限制性的实施例中，图1所示步骤S101可以包括以下步骤：
确定参考逻辑信道，并将所述参考逻辑信道的标识信息加入所述优先级信息；确定所述信道状态信息的优先级与所述参考逻辑信道的优先级的比值，以加入所述优先级信息。
本实施例中，优先级信息可以间接地指示CSI的优先级，也即优先级信息可以包括参考逻辑信道的标识信息以及比值，由此，接收用户设备可以通过参考逻辑信道的标识信息找到所述参考逻辑信道，进而计算参考逻辑信道的优先级与比值的乘积来获得CSI的优先级。
具体而言，优先级信息中的参考逻辑信道的标识信息可以采用单个比特来表示，例如比特0或比特1，比特0表示参考逻辑信道为优先级最高的逻辑信道，比特1表示参考逻辑信道为优先级最低的逻辑信道，或者比特1表示参考逻辑信道为优先级最高的逻辑信道，比特0表示参考逻辑信道为优先级最低的逻辑信道。
又或者，优先级信息中的参考逻辑信道的标识信息可以是参考逻辑信道的逻辑信道标识，例如，当确定逻辑信道2为参考逻辑信道时，在优先级信息中指示逻辑信道标识＝2。
本发明另一个非限制性的实施例中，图1所示步骤S101可以包括以下步骤：
确定参考逻辑信道，并将所述参考逻辑信道的标识信息加入所述 优先级信息；确定所述信道状态信息的优先级与所述参考逻辑信道的优先级的差值，以加入所述优先级信息。
与前述实施例不同的是，本实施例中，优先级信息包括的不是比值而是差值。由此，接收用户设备可以通过计算参考逻辑信道的优先级与差值的和来获得CSI的优先级。
在本实施例中，所述差值可以是正整数，也可以是小于0的负整数，也可以是0。
进一步地，在确定参考逻辑信道时，可以从与承载所述信道状态信息的信令处于同一传输链路的逻辑信道中，确定所述参考逻辑信道，传输链路由承载所述信道状态信息的信令的源地址和/或目标地址来界定。
具体地，承载所述信道状态信息的信令可以是MAC CE。在这种情况下，参考逻辑信道可以从与CSI MAC CE处于同一传输链路的逻辑信道中确定。
具体地，承载所述信道状态信息的信令可以是物理层信令。在这种情况下，参考逻辑信道可以从与承载CSI的物理层信令处于同一传输链路的逻辑信道中确定。
例如，对于用户设备1和用户设备2之间的直连链路，具有逻辑信道1、逻辑信道2和逻辑信道3，其优先级分别为2、4和5，其中，数值越小表示优先级越高。在这种情况下，可以确定参考逻辑信道为该直连链路上优先级最高的逻辑信道，也即逻辑信道1，其优先级为2。如果此时优先级信息中包括比值为3，则可以确定CSI的优先级为2×3＝6。如果此时优先级信息中包括差值为3，则可以确定CSI的优先级为2+3＝5。
又例如，对于用户设备1和用户设备2之间的直连链路，具有逻辑信道1、逻辑信道2和逻辑信道3，其优先级分别为2、4和5，其中，数值越小表示优先级越高。在这种情况下，可以确定参考逻辑信 道为该直连链路上逻辑信道标识为2的逻辑信道，也即逻辑信道2，其优先级为4。如果此时优先级信息中包括比值为0.5，则可以确定CSI的优先级为4×0.5＝2。如果此时优先级信息中包括差值为-2，则可以确定CSI的优先级为-2+4＝2。
又例如，对于用户设备1和用户设备2之间的直连链路，具有逻辑信道1、逻辑信道2和逻辑信道3，其优先级分别为2、4和5，其中，数值越小表示优先级越高。在这种情况下，可以确定参考逻辑信道为该直连链路上优先级最高的逻辑信道，也即逻辑信道1，其优先级为2。如果此时优先级信息中包括比值为1，则可以确定CSI的优先级为2。如果此时优先级信息中包括差值为0，则可以确定CSI的优先级为2。此时，用户设备1和用户设备2之间的直连链路上的CSI的优先级实际即为用户设备1和用户设备2之间的直连链路上最高逻辑信道的优先级。
又例如，对于用户设备1和用户设备2之间的直连链路，具有逻辑信道1、逻辑信道2和逻辑信道3，其优先级分别为2、4和5，其中，数值越小表示优先级越高。在这种情况下，可以确定参考逻辑信道为该单播链路上逻辑信道标识为2的逻辑信道，也即逻辑信道2，其优先级为4。如果此时优先级信息中包括比值为1，则可以确定CSI的优先级为4。如果此时优先级信息中包括差值为0，则可以确定CSI的优先级为4。此时，用户设备1和用户设备2之间的单播链路上的CSI的优先级实际即为用户设备1和用户设备2之间的直连链路上逻辑信道2的优先级。
可选的，在确定参考逻辑信道时，也可以从有数据的逻辑信道中，确定所述参考逻辑信道。
例如，对于用户设备1来说，和一个或多个用户设备具有逻辑信道1、逻辑信道2和逻辑信道3，其优先级分别为2、4和5，其中，数值越小表示优先级越高，且逻辑信道2和逻辑信道3目前有待发送数据。在这种情况下，可以确定参考逻辑信道为有待传输数据的逻辑 信道中优先级最高的逻辑信道，也即逻辑信道2，其优先级为4。如果此时优先级信息中包括比值为0.5，则可以确定CSI的优先级为4×0.5＝2。如果此时优先级信息中包括差值为-2，则可以确定CSI的优先级为-2+4＝2。
本发明一个非限制性的实施例中，图1所示步骤S101可以包括以下步骤：确定所述优先级信息为参考逻辑信道的标识信息，以使接收用户设备确定所述信道状态信息的优先级为所述参考逻辑信道的标识信息指示的参考逻辑信道的优先级。
本实施例中，优先级信息可以间接地指示CSI的优先级。具体地，优先级信息中包括的是参考逻辑信道的标识信息，参考逻辑信道的标识信息能够指示参考逻辑信道，参考逻辑信道具备优先级。由此，接收用户设备可以确定CSI的优先级为所述参考逻辑信道的标识指示的参考逻辑信道的优先级。
具体而言，优先级信息中的参考逻辑信道的标识信息可以采用单个比特来表示，例如比特0或比特1，比特0表示为优先级最高的逻辑信道为参考逻辑信道，比特1表示优先级最低的逻辑信道为参考逻辑信道，或者比特1表示优先级最高的逻辑信道为参考逻辑信道，比特0表示优先级最低的逻辑信道为参考逻辑信道。
又或者，优先级信息中的参考逻辑信道的标识信息可以是逻辑信道标识，例如，可以指示参考信道为逻辑信道标识为2的逻辑信道。
可选地，在确定参考逻辑信道时，可以从与承载所述信道状态信息的信令处于同一传输链路的逻辑信道中，确定所述参考逻辑信道，传输链路由承载所述信道状态信息的信令的源地址和/或目标地址来界定。
可选地，在确定参考逻辑信道时，可以从有数据的逻辑信道中，确定所述参考逻辑信道。
关于本实施例的更多具体实施方式可参照前述实施例，此处不再 赘述。
本发明一个非限制性的实施例中，所述优先级信息包括信道状态信息的优先级。
与前述实施例均不同的是，本发明实施例中的优先级信息可以直接地指示CSI的优先级，也即优先级信息包括CSI的优先级。
进一步地，所述优先级信息中包括的信道状态信息的优先级，可以是具体的优先级数值，例如携带优先级5，则可确定CSI的优先级为5，或者，可以指示CSI的优先级高于承载数据的逻辑信道的优先级，或者，低于承载数据的逻辑信道的优先级。
例如，当所述信道状态信息中包括的信道状态信息的优先级，指示CSI的优先级高于承载数据的逻辑信道的优先级，那么在执行LCP过程中，在需要发送CSI时，根据承载所述信道状态信息的信令的源地址和/或目标地址确定传输链路；在所述传输链路上为CSI MAC CE分配传输资源，也即优先为CSI分配传输资源。在不存在需要发送的CSI时，则确定最高优先级的允许发送数据的待传输逻辑信道对应的源地址和/或目标地址，以用于确定传输链路。
又例如，当所述信道状态信息中包括的信道状态信息的优先级，指示CSI的优先级低于承载数据的逻辑信道的优先级，那么在执行LCP过程时，在需要且允许发送待传输数据时，则确定允许发送数据的最高优先级的待传输逻辑信道对应的源地址和/或目标地址，以用于确定传输链路，在不需要或不允许发送待传输数据时，而需要发送CSI时，根据承载所述信道状态信息的信令的源地址和/或目标地址确定传输链路；在所述传输链路上为CSI MAC CE分配传输资源。
本发明一个非限制性的实施例中，图1所示步骤S102可以包括以下步骤：发送物理层信令，所述物理层信令包括下行控制信息(Downlink Control Information,DCI)或直接链路控制信息(Sidelink Control Information,SCI)；或者发送高层信令，所述高层信令包括无 线资源控制(Radio Resource Control,RRC)信令。需要说明的是，在图1所示的方法及所有相关发明实施例中，所述控制信息中的信道状态信息的优先级信息中的全部或部分内容，可以由预配置确定，从而不需要携带在控制信息中。
例如，当预先规定参考逻辑信道为最高优先级逻辑信道，且预先规定CSI优先级为参考逻辑信道的优先级和信道状态信息的优先级与所述参考逻辑信道的优先级的比值的乘积，那么信道状态信息的优先级信息可以仅包括信道状态信息的优先级与所述参考逻辑信道的优先级的比值，从而根据最高优先级逻辑信道的优先级和信道状态信息的优先级与所述参考逻辑信道的优先级的比值，确定CSI的优先级。
又例如，当预先规定参考逻辑信道为与承载所述信道状态信息的信令处于同一传输链路的逻辑信道中的最低优先级逻辑信道，且预先规定CSI的优先级为参考逻辑信道的优先级，那么不需要在控制信息中携带信道状态信息的优先级信息，仍然可以确定CSI的优先级为与承载所述信道状态信息的信令处于同一传输链路的逻辑信道中最低优先级逻辑信道的优先级。
又例如，当预先规定CSI的优先级低于承载数据的逻辑信道的优先级，那么不需要在控制信息中携带道状态信息的优先级信息，仍然可以确定CSI的优先级低于承载数据的逻辑信道的优先级。
请参照图2，信道状态信息的优先级确定方法可以用于接收用户设备侧，接收用户设备是指接收V2X数据的用户设备。具体可以由接收用户设备执行图2所示方法的各个步骤：
步骤S201：接收控制信息，所述控制信息包括信道状态信息的优先级信息；
步骤S202：至少根据所述控制信息确定信道状态信息的优先级。
本实施例中，由于控制信息中携带有信道状态信息的优先级信 息，因此接收用户设备可以至少根据所述控制信息中的优先级信息确定信道状态信息的优先级。
具体地，在CSI的优先级信息直接地指示CSI的优先级时，接收用户设备可以直接根据CSI的优先级信息确定CSI的优先级。在CSI的优先级信息间接地指示CSI的优先级时，接收用户设备需要根据CSI的优先级信息中CSI的优先级的计算方式来计算获得CSI的优先级。
关于本实施例的更多具体实施方式可参照前述实施例，在此不再赘述。
在本发明一个非限制性的实施例中，所述优先级信息包括信道状态信息的优先级与参考逻辑信道的优先级的比值，以及所述参考逻辑信道的标识信息。请参照图3，图2所示步骤S202具体可以包括以下步骤：
步骤S301：根据所述控制信息确定所述比值以及参考逻辑信道；
步骤S302：计算所述参考逻辑信道的优先级与所述比值的乘积，并根据计算结果确定信道状态信息的优先级。
本实施例中，接收用户设备可以计算参考逻辑信道的优先级与所述比值的乘积，并可以直接将计算结果作为CSI的优先级。
在本发明另一个非限制性的实施例中，所述优先级信息包括信道状态信息的优先级与参考逻辑信道的优先级的差值，以及所述参考逻辑信道的标识信息。请参照图4，图2所示步骤S202具体可以包括以下步骤：
步骤S401：根据所述控制信息确定所述差值以及参考逻辑信道；
步骤S402：计算所述参考逻辑信道的优先级与所述差值的之和，并根据计算结果确定信道状态信息的优先级。
本实施例中，接收用户设备可以计算参考逻辑信道的优先级与所 述差值的乘积，并可以直接将计算结果作为CSI的优先级。
进一步地，图3所示步骤S302或图4所示步骤S402具体可以包括以下步骤：
如果所述计算结果处于最低优先级数值以及最低优先级数值之间，则直接确定所述计算结果为信道状态信息的优先级；或者，如果所述计算结果小于最低优先级数值，则确定最低优先级为信道状态信息的优先级；或者，如果所述计算结果大于最高优先级数值，则确定最高优先级为信道状态信息的优先级。
具体实施中，由于优先级具有数值范围，也即最低优先级数值以及最高优先级数值，例如为0到7。那么最终确定的CSI的优先级也应处于该数值范围内，以保证CSI优先级的有效性。
例如，逻辑信道优先级的数值范围为0到7。对于用户设备1和用户设备2之间的单播链路，具有逻辑信道1、逻辑信道2和逻辑信道3，其优先级分别为2、4和5，其中，数值越小表示优先级越高。在这种情况下，可以确定参考逻辑信道为该单播链路上优先级最高的逻辑信道，也即逻辑信道1，其优先级为2。如果此时优先级信息中包括比值为4，则可以确定CSI的优先级为2×4＝8。由于8明显大于逻辑信道的最高优先级数值7，因此可以确定CSI的优先级为7。
又例如，对于用户设备1和用户设备2之间的单播链路，具有逻辑信道1、逻辑信道2和逻辑信道3，其优先级分别为4、5和6。在这种情况下，可以确定参考逻辑信道为该单播链路上优先级最高的逻辑信道，也即逻辑信道1，其优先级为4。如果此时优先级信息中包括差值为-5，则可以确定CSI的优先级为4+(-5)＝-1。由于-1明显超过逻辑信道的最低优先级数值0，因此可以确定CSI的优先级为0。
在本发明一个非限制性的实施例中，所述优先级信息包括参考逻辑信道的标识信息，图2所示步骤S202可以包括以下步骤：确定所述控制信息中所述参考逻辑信道的标识信息指示的参考逻辑信道的 优先级为信道状态信息的优先级。
具体地，参考逻辑信道的标识信息可以指示优先级最高的逻辑信道或者优先级最低的逻辑信道，这种情况下，参考逻辑信道的标识信息可以采用单个比特来表示，例如比特0或比特1，比特0表示优先级最高的逻辑信道，比特1表示优先级最低的逻辑信道，或者比特1表示优先级最高的逻辑信道，比特0表示优先级最低的逻辑信道。
参考逻辑信道的标识也可以指示具体的逻辑信道。例如，优先级信息指示逻辑信道2为参考逻辑信道，而用逻辑信道2的优先级作为CSI的优先级，那么参考逻辑信道的标识可以是ID＝2。
在本发明一个非限制性的实施例中，所述优先级信息包括信道状态信息的优先级，图2所示步骤S202可以包括以下步骤：确定所述控制信息中指示的优先级为信道状态信息的优先级。
本实施例中，由于优先级信息直接指示CSI的优先级，因此接收用户设备可以直接确定优先级信息中的优先级为CSI的优先级。
具体地，所述优先级信息中包括的信道状态信息，可以是具体的优先级，例如携带优先级5，则可确定CSI的优先级为5，或者，可以指示CSI的优先级高于承载数据的逻辑信道，或者，低于承载数据的逻辑信道。
需要说明的是，在图2所示的方法及所有相关发明实施例中，所述控制信息中的信道状态信息的优先级信息中的全部或部分内容，可以由预配置确定，从而不需要携带在控制信息中。
具体实施方式可参照图1所述实施例，在此不再赘述。请参照图5，本发明实施例还公开了一种信道状态信息的优先级发送装置50，优先级发送装置50可以包括：
优先级信息确定模块501，用以确定信道状态信息的优先级信息；
控制信息发送模块502，用以发送控制信息，所述控制信息包括 信道状态信息的优先级信息。
本发明实施例中，由于CSI通常与发送用户设备要发送的业务数据有关，而只有发送用户设备和/或基站才拥有要发送的业务数据特征信息，因此信道状态信息的优先级可以由发送用户设备或基站指示给接收用户设备，也即可以由发送用户设备或基站通过控制信息来进行指示，以使得接收用户设备能够通过控制信息来确定信道状态信息的优先级，实现了信道状态信息的优先级确定的便捷性。
