1. A method for feeding back channel state information, comprising:
a base station notifying a terminal of transmission resources used for transmitting a plurality of Channel State Information (CSIs) or a plurality of colliding CSIs and/or of priorities between a plurality of CSIs or a plurality of colliding CSIs, wherein, the base station notifies the terminal by at least one of the following ways: a terminal dedicated high layer signaling, a physical downlink control signaling and a preset rule, wherein, the step of a base station notifying a terminal of transmission resources used for transmitting a plurality of channel state information CSIs or a plurality of colliding CSIs comprises: the base station configuring collision resolution resources used for transmitting a plurality of CSIs or a plurality of colliding CSIs for the terminal through the terminal dedicated high layer signaling, and indicating the terminal to, if the plurality of CSIs have a collision in a same collision resolution resource, orderly transmit the colliding CSIs in the collision resolution resource according to the priorities, and/or, wherein, the step of a base station notifying a terminal of transmission resources used for transmitting colliding CSIs comprises: the base station configuring a plurality of sets of collision resolution resources used for transmitting the colliding CSIs for the terminal through the terminal dedicated high layer signaling, wherein, a set of collision resolution resources include collision resolution resources of one or more colliding CSIs; and indicating the terminal to, if the plurality of CSIs have a collision in a same resource, orderly transmit the colliding CSIs in one set of the plurality of sets of collision resolution resources according to the priorities, and/or, wherein, the step of a base station notifying a terminal of transmission resources used for transmitting colliding CSIs comprises: the base station configuring Physical Uplink Shared Channel (PUSCH) resources used for transmitting colliding CSIs for the terminal through the terminal dedicated high layer signaling, and indicating the terminal to feed back all or part of the colliding CSIs through the PUSCH resources on subframes with CSI collision, and/or, wherein, the step of a base station notifying a terminal of transmission resources used for transmitting colliding CSIs comprises: the base station configuring PUSCH resources used for transmitting colliding CSIs through the terminal dedicated high layer signaling, and indicating the terminal to: on subframes with CSI collision, if no aperiodic triggered feedback and no PUSCH transmission exist, feed back all or part of the colliding CSIs through the PUSCH resources; and if the aperiodic triggered feedback and the PUSCH transmission exist, transmit aperiodic triggered CSIs or all or part of the colliding CSIs or CSIs with a highest priority according to aperiodic triggering and PUSCH transmission resources, and/or, wherein, the step of a base station notifying a terminal of transmission resources used for transmitting colliding CSIs comprises: the base station configuring a plurality of sets of PUSCH resources used for transmitting colliding CSIs through the terminal dedicated high layer signaling, and indicating the terminal to feed back all or part of the colliding CSIs through one set of the plurality of sets of PUSCH resources on subframes with CSI collision, and/or, wherein, the step of a base station notifying a terminal of transmission resources used for transmitting colliding CSIs comprises: the base station configuring a plurality of sets of PUSCH resources used for transmitting colliding CSIs through the terminal dedicated high layer signaling, and indicating the terminal to: on subframes with CSI collision, if no aperiodic triggered feedback and no PUSCH transmission exist, feed back all or part of the colliding CSIs through one set of the plurality of sets of PUSCH resources; and when the aperiodic triggered feedback and/or the PUSCH transmission exist, transmit aperiodic triggered CSIs or all or part of the colliding CSIs or CSIs with the highest priority according to aperiodic triggering and/or PUSCH transmission resources, and/or, wherein, the step of a base station notifying a terminal of transmission resources used for transmitting colliding CSIs comprises: when the base station triggers a terminal PUSCH resource allocation and/or sends uplink data on subframes by which the terminal feeds back a plurality of CSIs or a plurality of subframes with CSI collision, the base station indicating the terminal to send the plurality of CSIs or part or all of the colliding CSIs or the CSIs with the highest priority in the allocated PUSCH resources, and/or, wherein, the step of a base station notifying a terminal of transmission resources used for transmitting colliding CSIs comprises: when the base station triggers a terminal PUSCH resource allocation and/or sends uplink data on subframes by which the terminal feeds back a plurality of CSIs or a plurality of subframes with CSI collision, and no aperiodic feedback is triggered, the base station indicating the terminal to send the plurality of CSIs or all or part of the colliding CSIs or the CSIs with the highest priority in the allocated PUSCH resources. |
