Method and arrangement in a wireless communication network
First Claim
1. A method in a relay node for selecting a communication mode, which relay node is configured to communicate with a base station via a donor antenna over a first link and to communicate with a user equipment via a coverage antenna over a second link, comprising:
- obtaining an isolation value, based on a radio wave isolation between the donor antenna and the coverage antenna;
comparing the isolation value with a threshold level value;
configuring the relay node to communicate in full duplex mode if the isolation value exceeds the threshold level value, and to communicate in half duplex mode if the isolation value does not exceed the threshold level value; and
transmitting information concerning a configured duplex mode of the relay node to the base station.

Abstract
Method and arrangement in a relay node, for selecting communication mode. The relay node is configured to communicate with a base station via a donor antenna over a first link and to communicate with a user equipment via a coverage antenna over a second link. The method comprises obtaining an isolation value, based on the radio wave isolation between the relay donor antenna and the relay coverage antenna. The obtained isolation value is compared with an isolation threshold level value. The relay node is configured to communicate in full duplex mode if the obtained isolation value exceeds the isolation threshold level value, otherwise in half duplex mode. Information concerning the configured duplex mode of the relay node is transmitted to the base station.
Also a method and arrangement in a base station is described.
