摘要： 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 center (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.

摘要翻译： 方法和无线电节点（500），用于根据时分双工TDD方案控制发射模式和接收模式之间的通信模式的改变。 无线电节点具有用于无线电信号的发送和接收的至少两个并行分支（504,06），其中分支当前以第一通信模式操作。 无线电节点获得由一个或多个分支产生的一个或多个指示信号（S1A，S1B），以指示第一模式已被关闭。 当确定在故障分支中没有关闭第一通信模式时，例如， 通过不从该分支在时间上接收到指示信号，故障分支中的第一模式被禁止，和/或故障分支被报告给监控中心（510）。 因此，当分支中的一个不对准或其他错误时可以发现，并且可以采取适当的动作来修复或更换故障分支。
