METHOD AND APPARATUS OF TRANSMITTING FEEDBACK REQUEST, RECEIVING FEEDBACK REQUEST IN WIRELESS COMMUNICATION SYSTEM

摘要

A method for transmitting a feedback request in a wireless communication system is provided. The method includes: transmitting feedback request control information to a user equipment (UE), wherein the feedback request control information includes a MIMO (Multi-Input Multi-Output) feedback bitmap indicating at least one MIMO feedback mode to be applied to the UE and a common parameter, and the common parameter comprises a parameter commonly requested for the UE to generate feedback information in the at least one MIMO feedback mode.
