METHOD FOR RESOURCE ALLOCATION, METHOD FOR CHANNEL STATE INFORMATION TRANSMISSION, BASE STATION AND USER EQUIPMENT

摘要

A method for resource allocation, method for channel state information transmission, base station and user equipment. Wherein the method for resource allocation includes: determining, by a base station, that it is necessary for a UE to report aperiodic CSI of relevant downlink CCs; and allocating, by the base station, corresponding resources to the UE according to the number of the relevant downlink CCs. The base station allocates corresponding resources to the UE in accordance with the number of relevant downlink CCs, resource allocation is flexible, and the transmission of UCI in case of multiple carriers is supported.

1. A method performed by a user equipment, comprising:
receiving downlink control information transmitted by a base station, the downlink control information comprising an index of coding and modulation scheme and triggering information which indicates whether to perform an aperiodic reporting of channel status information of relevant downlink component carriers, and when indicated to perform the aperiodic reporting of channel status information of the relevant downlink component carriers, the downlink control information indicates an index and number of the relevant downlink component carriers, wherein the maximum number of resources allocated by the base station to the user equipment is a first number if the user equipment should perform the aperiodic reporting of channel status information of one downlink component carrier; and the maximum number of the resources allocated by the base station to the user equipment is a second number if the user equipment should perform the aperiodic reporting of channel status information of more than one downlink component carrier; transmitting an aperiodic report of the channel status information according to the triggering information, the index of coding and modulation scheme and used resources contained in the downlink control information.
