摘要： The present disclosure relates to a pre-5th-Generation (5G) or 5G communication system to be provided for supporting higher data rates beyond 4th-Generation (4G) communication system such as long term evolution (LTE). A terminal in a wireless communication system is provided. The terminal includes a transceiver, and at least one processor configured to receive, from a base station (BS), a beam failure recovery configuration comprising at least one reference signal for identifying a candidate beam for the beam failure recovery and associated random access (RA) parameters, identify the candidate beam for the beam failure recovery using the at least one reference signal, and perform a physical random access channel (PRACH) using the at least one reference signal and the associated RA parameters on the candidate beam for the beam failure recovery.

摘要： The disclosure relates to a pre-5th-generation (5G) or 5G communication system to be provided for supporting higher data rates beyond 4th-generation (4G) communication system, such as long term evolution (LTE). A method for operating a management device in a wireless communication system is provided. The method includes obtaining measurement results of a plurality of cells respectively, identifying an aggressor cell and a victim cell by atmospheric interference among the plurality of the cells, based on the measurement results, and performing interference control on at least one of the aggressor cell or the victim cell, wherein the measurement results include interference information related to a downlink signal of at least one other cell measured in an uplink resource duration of a measurement cell and cell information of the at least one other cell.

摘要： The present disclosure provides a method and an apparatus for scheduling traffic in a wireless communication system. A method for a base station operating in a wireless communication system according to an embodiment of the present disclosure comprises the steps of: receiving feedback information from a plurality of terminals; and scheduling the plurality of terminals based on the feedback information, wherein the step of scheduling the plurality of terminals includes a step of scheduling so as to reduce throughput of terminals in a first group of the plurality of terminals that are in an overload state, and to satisfy delay-based quality of service (QoS) of terminals in a second group of the plurality of terminals that are in under-load state. As a result, the total utility of all the terminals can be maximized, a delay-based QoS with respect to all the terminals can be achieved on average, and a minimum data rate-based QoS can be achieved on average.

摘要： A method and an apparatus for effectively determining a terminal which will transmit or receive packets in a packet-based wireless network are provided. The scheduling method of a base station of a wireless communication system includes determining a first status variable for an increment of whole network utility to data amount allocated to at least one terminal and a second status variable for an increment of the whole network utility to a scheduling chance allocated to the terminal, determining a scheduling metric based on the first and second status variables, and scheduling the at least one terminal based on the scheduling metric.
