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.

主权项

1. A base station, comprising:
a control circuit configured to:
allocate corresponding resources to a user equipment according to a number of relevant downlink component carriers of which the user equipment should perform an aperiodic reporting of channel status information,allocate maximum resources of a first number to the user equipment when the user equipment should perform the aperiodic reporting of channel status information of one downlink component carrier, andallocate maximum resources of a second number to the user equipment when the user equipment should perform the aperiodic reporting of channel status information of more than one downlink component carrier; anda transmitter configured to transmit downlink control information to the user equipment,wherein the downlink control information further comprises an index of coding and modulation scheme, wherein resources are allocated to the user equipment by the base station according to the number of the relevant downlink component carriers, and wherein the user equipment is further configured to perform aperiodic transmission of channel status information according to triggering information, the index of coding and modulation scheme and used resources contained in the downlink control information.
