    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.

    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 translation: 提供一种在无线通信系统中操作终端的方法。 该方法包括使用第一射频（RF）路径向主小区发送数据和从主小区接收数据中的至少一个，并且当二次小区被去激活时，操作第二RF路径以执行与之相关的搜索和测量 至少一个目标小区的频率不同于主小区的频率。
