METHOD AND APPARATUS FOR TRANSMITTING AND RECEIVING CHANNEL STATE INFORMATION IN A WIRELESS COMMUNICATION SYSTEM

WIPO Patent Application WO/2012/108645

A3

The present invention relates to a method and apparatus for transmitting and receiving channel state information in a wireless communication system. According to one embodiment of the invention, the method for receiving channel state information in a wireless communication system comprises the steps of: setting report request indication information indicating a report on non-periodic channel state information of a user terminal in a first field of a payload and setting mode indication information representing a reporting method on the channel state information implicitly in a second field; transmitting a signal in which the payload including the first field and the second field is encoded to the user terminal and receiving a signal including channel state information from the user terminal; and decoding the received signal according to the reporting method indicated by the mode indication information to extract the channel state information. The mode indication information indicates a single mode or multi modes and can be distinguished by a mode identifier calculated in at least one of a carrier aggregation framework and transmission method, and an adaptive modulation method of the report request indication information and the user terminal.
