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 method of operating a base station for interference cancellation in a wireless communication system is provided. The method may include receiving, from a target terminal, an uplink data signal including at least one interference signal generated by at least one interference terminal; performing a primary decoding for the uplink data signal; in accordance with decoding errors, generating a cancelling signal corresponding to an interference signal of the at least one interference terminal; performing a cancellation by applying the cancelling signal to the uplink data signal; and performing a secondary decoding for the uplink data signal to which the cancelling signal has been applied.

Interference cancellation method and base station apparatus therefor

An inter-cell interference coordination method and apparatus is provided for mitigating inter-cell interference in a wireless communication system by using interference coordination information exchanged among neighbor base stations. The method includes receiving, at a serving base station, power control messages transmitted by neighbor base stations, receiving incoming interference coordination messages transmitted by neighbor base stations, each message including interference indicators of resource blocks, allocating the resource blocks with transmission power per resource block to user equipments served by the base station based on the power control and interference coordination messages, generating outgoing interference coordination messages for the respective neighbor base stations based on the resource block allocation result, and transmitting the interference coordination messages to the neighbor base stations, respectively.

Inter-cell interference coordination method and apparatus for wireless communication system

A method and an apparatus are provided that transmit and receive a random access preamble in a wireless communication system. A plurality of random access parameters having different values in accordance with a plurality of events for triggering random access are set. When one of the plurality of events for triggering random access has occurred, random access is performed according to at least one of the plurality of random access parameters corresponding to the event. Therefore, the time delay of random access can be reduced.
