METHOD AND ARRANGEMENT IN WIRELESS COMMUNICATION NETWORK Russian patent published in 2014 - IPC H04B7/14 

FIELD: radio engineering, communication.

SUBSTANCE: invention relates to wireless communication. A method and an arrangement in a relay node for selecting a communication mode. The relay node is configured to communicate with a base station through a donor antenna via a first link and to communicate with user equipment through a coverage antenna via a second link. The method comprises obtaining an isolation value based on radio wave isolation between the relay donor antenna and the relay coverage antenna. The obtained isolation value is compared with a threshold isolation level. The relay node is configured to communicate in full duplex mode if the obtained isolation value exceeds the isolation threshold level and in half-duplex mode otherwise. Information regarding the configured duplex mode of the relay node is transmitted to the base station. A method and an arrangement in a base station are also described.

EFFECT: providing a mechanism for improving efficiency in a wireless communication network.
