METHOD AND APPARATUS FOR PERFORMING COMMUNICATION IN A WIRELESS COMMUNICATION SYSTEM
First Claim
1. A method for performing communication in a wireless communication system, the method comprising:
- identifying a transmission mode configured for a serving cell by a Base Station (BS), by a User Equipment (UE);
identifying an antenna configuration of the BS by the UE;
determining the number of bits for a Rank Indication (RI) representing the number of layers based on the transmission mode and the antenna configuration; and
generating an RI using the determined number of bits and transmitting the RI in transmission resources of the serving cell to the BS by the UE.
