Abstract: A method for operating a terminal in a wireless communication system is provided. The method includes at least one of transmitting data to and receiving data from a primary cell using a first Radio Frequency (RF) path, and, when a secondary cell is deactivated, operating a second RF path to perform searching and measurement with respect to at least one target cell at a frequency different from a frequency of the primary cell.

Abstract: Methods and apparatuses are provided for controlling retransmission by a User Equipment (UE) in a communication system. A negative acknowledgement (NACK) is received, from a Node B, for at least one transport block among a plurality of transport blocks transmitted by the UE. A precoding matrix and a number of layers for retransmission are determined. The at least one transport block is retransmitted using the determined precoding matrix and the determined number of layers. The precoding matrix is predefined and the number of layers is equal to a number of layers corresponding to the at least one transport block, if the UE does not receive a physical downlink control channel (PDCCH) intended for the UE and a number of the at least one transport block is not equal to a number of the plurality of transport blocks.
