Abstract:
A method and apparatus for configuring a control channel between a first transceiver and a second transceiver in a communication system are provided. The method includes generating, by the first transceiver, a signaling message including information for the control channel; transmitting, by the first transceiver, the signaling message including information for the control channel to the second transceiver; generating, by the first transceiver, the control channel based on the information for the control channel; and transmitting, by the first transceiver, the generated control channel to the second transceiver, wherein the information for the control channel includes resource allocation information, and information related to whether interleaving applied and a type of reference signal.

Abstract:
Methods and apparatuses are provided for Channel State Information (CSI) feedback. An Uplink (UL) grant is received from a Node B. Information included in the UL grant is identified. If the information is mapped to at least one DownLink (DL) Component Carrier (CC) based on configuration information relating to at least one set including the at least one DL CC, at least one CSI corresponding to the at least one DL CC is generated. The generated at least one CSI is transmitted to the Node B.

Abstract:
A method and apparatus of a user equipment (UE) for transmitting and receiving data in a wireless communication system. The UE receives first time division duplex (TDD) uplink-downlink configuration information for a first cell and second TDD uplink-downlink configuration information for a second cell, determines whether a subframe in the first cell is a special subframe and the subframe in the second cell is a downlink subframe according to the first and second TDD uplink-downlink configuration information, and determine, if the subframe in the first cell is the special subframe and the subframe in the second cell is the downlink subframe, not to receive a signal on the second cell in orthogonal frequency division multiplexing (OFDM) symbols that overlaps with at least one of a guard period (GP) or uplink pilot time slot in the first cell.
Abstract:
A Channel Status Information (CSI) transmission method and apparatus of a terminal are provided for use in a wireless communication system. In the wireless communication system supporting carrier aggregation, the terminal transmits the CSIs of component carriers without conflict of their transmission time points, resulting in an improvement of system performance. In a case where the transmission time points are determined to overlap unavoidably, the terminal transmits the CSI as compressed.

Abstract:
The present disclosure relates to a technique for radio link monitoring in a wireless communication system, and to operation procedures of the base station and user equipment and a method for radio link quality evaluation on the basis of the technique. In the method, the user equipment divides the downlink channel bandwidth into multiple frequency ranges, measures channel states for each frequency range, and evaluates the radio link quality based on channel state measurement results. Thereafter, the user equipment sends frequency range quality information to the base station, which may then utilize the same for downlink resource allocation. Hence, it is possible to solve the problem of the existing scheme wherein the user equipment enters the physical layer problem detection state or the radio link failure state although a frequency range usable for service provisioning is present within the downlink channel bandwidth.
