A communication method and system for converging a 5th-generation (5G) communication system for supporting higher data rates beyond a 4th-generation (4G) system with a technology for Internet of things (IoT) are provided. The disclosure may be applied to intelligent services based on the 5G communication technology and the IoT-related technology, such as smart home, smart building, smart city, smart car, connected car, health care, digital education, smart retail, security and safety services.

Method and apparatus for transmitting and receiving group downlink control channel in wireless communication system

The disclosure provides a method of transmitting downlink (DL) control information, the method including: transmitting configuration information about a CORESET in which DL control information is to be transmitted; mapping the DL control information to a plurality of resource elements (REs) in the CORESET determined based on the configuration information; and transmitting the DL control information via the plurality of REs.

Method and apparatus for transmitting and receiving control information in wireless communication system

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.

Method and apparatus for transceiving channel related to terminal that supports half duplex transmission in mobile communication system

Disclosed is a method by a terminal in a mobile communication system including receiving, from a base station, CSI measurement configuration information for a serving cell, measuring a first reference signal for obtaining reference signal received power (RSRP) information based on the first CSI configuration information related to the RSRP for the physical layer signaling, transmitting the RSRP information to the base station through the physical layer signaling, measuring a second reference signal for obtaining CSI, and transmitting the CSI to the base station, the first CSI configuration information including information indicating whether to use group based reporting for the RSRP information, and the first CSI configuration information including information indicating a number of antenna ports for the RSRP information when the group based reporting is not configured for the RSRP information.

Channel status information feedback method and apparatus for a distributed antenna mobile communication system

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.

Method and apparatus for transmitting/receiving CSI in cellular communication system supporting carrier aggregation

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.

Method and device for monitoring frequency domain-based wireless link in wireless communication system

A method of transmitting channel state information. The method includes receiving, from a base station, channel measurement information comprising a plurality of antenna ports to be measured for a serving cell; measuring signals related to the plurality of antenna ports based on the channel measurement information; transmitting reference signal received power (RSRP) information for the plurality of antenna ports based on the measured signals; receiving, from the base station, in response to transmission of the RSRP information, channel state information (CSI) report instruction information for a candidate of a distributed antenna port set including at least one antenna port; measuring a channel state of the at least one antenna port in the candidate; and transmitting the measured channel state to the base station, wherein the candidate of the distributed antenna port set among the plurality of antenna ports is determined based on the RSRP information by the base station.

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.

Channel state information request/feedback method and apparatus

Disclosed are a method and an apparatus for transceiving a channel related to a terminal that supports half duplex transmission in a mobile communication system. The terminal receives scheduling information on multi-carriers having different TDD configurations from a base station, determines whether to receive a downlink channel for a plurality of different subframes of each multi-carrier including at least one special subframe, and transceives a channel to/from the base station depending on whether the downlink channel is received or not.

Provided is a method of transmitting control information of a base station in a mobile communication system includes obtaining scheduling information from a terminal; and transmitting at least two control channels through one down link carrier, wherein each control channel corresponds to a different uplink carrier.
