下面，将结合附图对本发明实施例提供的发送和接收CSI的方法和设备进行详细说明。
图2示出了根据本发明实施例的发送CSI的方法200的示意性流程图，如图2所示，该方法200包括：
S210，终端设备根据信道状态信息CSI满足CSI触发条件向网络设备发送资源请求消息，所述资源请求消息用于请求所述网络设备分配用于传输所述CSI的传输资源。
S220，所述终端设备从所述网络设备接收资源配置消息，所述资源配置消息用于配置所述传输资源。
S230，所述终端设备根据所述传输资源向所述网络设备发送所述CSI。
或者，方法200包括：
S240，所述终端设备根据所述CSI不满足所述CSI触发条件确定不发送所述CSI。
S210中，终端设备可以根据预设在该终端设备内的CSI触发条件确定 当前的CSI是否需要发送，例如，当CSI为信噪比(Signal-to-Noise Ratio，SNR)时，该CSI触发条件可以是当SNR的值大于或等于20分贝(dB)时不发送SNR消息，当SNR的值小于20dB时向网络设备发送SNR消息，其中，SNR的值大于或等于20dB说明当前终端设备受到的干扰较小，信道质量较好，无需上报SNR，当SNR的值小于20dB时说明当前终端设备受到的干扰较大，信道质量较差，终端设备需要向网络设备上报SNR，以便于网络设备增大发射功率或者采用其它发射方式增大SNR，这样，可以减少CSI的发送数量或者次数，从而节约了传输资源。
当终端设备根据CSI触发条件确定向网络设备发送CSI时，终端设备可以向网络设备请求分配传输资源用于发送CSI，例如，终端设备可以通过物理上行控制信道(Physical Uplink Control Channel，PUCCH)向网络设备发送资源请求消息，请求网络设备分配传输资源。网络设备可以通过下行信令为终端设备配置PUCCH资源，例如，网络设备可以通过无线资源控制(Radio Resource Control，RRC)信令为终端设备配置PUCCH资源。
S220中，终端设备可以通过从网络设备接收资源配置消息确定传输资源，例如，终端设备可以接收网络设备发送的承载于物理下行控制信道(Physical Downlink Control Channel，PDCCH)中的上行调度分配(Up-link grant)消息。
S230中，终端设备根据接收到的资源配置消息确定传输资源，并通过该传输资源向网络设备发送CSI，例如，可以通过资源配置消息配置的物理上行共享信道(Physical Uplink Shared Channel，PUSCH)向网络设备发送CSI。
上述实施例仅是举例说明，本发明实施例不限于此，根据本发明实施例的发送CSI的方法，终端设备根据CSI是否满足发送CSI的触发条件确定是否发送CSI，并在确定发送CSI之后向网络设备申请发送CSI的传输资源，从而可以减少发送CSI所占用的传输资源，并且提高了发送CSI的灵活性。
可选地，所述终端设备发送所述资源请求消息之前，所述方法还包括：
S201，所述终端设备从所述网络设备接收CSI触发条件消息。
S202，所述终端设备根据所述CSI触发条件消息确定所述CSI触发条件。
终端设备可以根据网络设备发送的CSI触发条件消息确定CSI触发条件，例如，终端设备可以接收网络设备发送的承载于PDCCH中的CSI触发 条件消息，从而确定CSI的触发条件。

可选地，所述CSI触发条件消息用于指示所述终端设备根据第一CSI与第二CSI的差值满足第一门限值以及所述第一CSI或所述第二CSI满足第二门限值，向所述网络设备发送所述资源请求消息，其中，所述第一CSI与所述第二CSI为不同信号的CSI。
终端设备还可以根据第二CSI与第一CSI的差值的小于第一门限值，且第二CSI小于第二门限值确定向网络设备发送资源请求消息，请求网络设备为终端设备分配用于发送第一CSI和第二CSI的传输资源，其中，第一CSI为该终端设备所在小区的信号的CSI，第二CSI为该终端设备的邻小区的信号的CSI，第一门限值与第二门限值可以相同也可以不同。网络设备可以根据第二CSI与第一CSI的差值的小于第一门限值确定邻小区的干扰信号的强度与终端设备所在小区的信号的强度很接近，并根据第二CSI小于第二门限值确定终端设备当前所处小区的信道状态较差，从而可以根据干扰情况调整信号发射方式。本发明实施例中，第一CSI和第二CSI也可以是同一小区不同类型的信号的CSI。
