摘要： A method and an apparatus for transmitting and receiving Time Division Duplex (TDD) frame configuration information are disclosed. The base station transmits TDD frame configuration information as system information to a user equipment through a common control channel so as to dynamically change the TDD frame configuration according to uplink and downlink traffic conditions. The base station may deliver the same system information to all user equipments in the cell, removing ambiguity in User Equipment (UE) operations and avoiding interference. In comparison to an existing method of delivering TDD frame configuration information through system information update, the disclosed method enables user equipments to rapidly cope with traffic changes. In addition, user equipments may receive and apply TDD frame configuration information at the same time.

摘要： A communication method and system for converging a 5G communication system for supporting higher data rates beyond a 4G system with a technology for Internet of Things (IoT) is disclosed. A method of a terminal in a wireless communication system is provided. The method includes receiving downlink control information (DCI) including frequency domain resource allocation information on a physical downlink control channel (PDCCH) from a base station, identifying an allocated resource for transmitting or receiving data based on the frequency domain resource allocation information, and transmitting or receiving the data on the allocated resource. When the frequency domain resource allocation information is based on a first bandwidth part of a first bandwidth and the DCI is for a second bandwidth part corresponding to a second bandwidth, the allocated resource is identified by applying a scaling factor based on the first bandwidth and the second bandwidth.

摘要： A user equipment (UE) for receiving control information in a wireless communication system includes a transceiver configured to receive a synchronization signal/physical broadcasting channel (SS/PBCH) block of an index i from a BS, wherein SS/PBCH block comprises a PBCH carrying master information block (MIB). The UE includes a processor configured to for the SS/PBCH block of the index i, determine a slot index n0 as a sum of an offset value and └i*M┘. The offset value is determined based on a first value O determined according to the index indicated in the MIB, wherein the index configures PDCCH monitoring occasions, and a second value μ indicated in the MIB, wherein the second value μ represents a subcarrier spacing configuration, wherein M is a positive number determined according to the index indicated in the MIB, and cause the transceiver to decode a PDCCH in the slot index n0.

摘要： The present invention defines a method for controlling uplink transmission power of a terminal in a communication system which is operated by combining heterogeneous systems. Specifically, the present invention defines a method for selectively applying a power control command in order to control uplink power of a terminal in a communication system which is operated by combining an LTE/LTE-A system with a system which applies a new radio access technology, and a method for differently operating power control units depending on whether beam sweeping is applied or not. Such methods efficiently control transmission power of a terminal, and lower the generation of uplink interference signals, thereby improving system efficiency.
