Abstract
A method and apparatus for performing communication in a wireless communication system are provided. The method includes 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.

A method for performing communication in a base station (BS) of a wireless communication system, the method comprising:
- transmitting, to a user equipment (UE), information about a number of antenna ports for a serving cell;
- identifying a number of bits for a rank indication (RI) based on a maximum number of layers for the UE;
- and
- receiving, from the UE, information about the RI based on the identified number of bits for the RI,
- wherein the maximum number of layers is determined based on the smaller between the number of antenna ports and a number of layers corresponding to a multiple input multiple output (MIMO) capability for a frequency band in a corresponding band combination.
An apparatus of a base station (BS) for performing communication in a wireless communication system, the apparatus comprising:
- a transceiver configured to transmit, to a user equipment (UE), information about a number of antenna ports for a serving cell, and receive, from the UE, information about a rank indication (RI) based on a number of bits for the RI;
- and
- a controller configured to identify the number of bits for the RI based on a maximum number of layers for the UE,
- wherein the maximum number of layers is determined based on the smaller between the number of antenna ports and a number of layers corresponding to a multiple input multiple output (MIMO) capability for a frequency band in a corresponding band combination.
