Abstract

Method and radio node(500) for controlling a change of communication mode between transmit mode and receive mode according to a Time Division Duplex TDD scheme. The radio node has at least two parallel branches (504 06) for transmission and reception of radio signals wherein the branches currently operate in a first communication mode. The radio node obtains one or more indication signals (S1A S1B) generated by one or more of the branches to indicate that the first mode has been turned off. When it is determined that the first communication mode has not been turned off in a faulty branch e.g. by not receiving an indication signal in time from that branch the first mode is disabled in the faulty branch and/or the faulty branch is reported to a supervision centre (510). Thereby it can be discovered when one of the branches is misaligned or otherwise faulty and suitable actions can be taken for repairing or replacing the faulty branch.
