Abstract
In a radio communications network using a TDD structure to communicate with UE terminals, a radio network node applies such a TDD structure that at least one guard period is included in each slot between a downlink transmission period containing at least one downlink symbol and an uplink reception period containing at least one uplink symbol. Each guard period represents an interval during which the radio network node does not transmit any data. The radio network node allocates the guard periods dynamically by checking whether at synchronization degradation criterion is fulfilled; and if at least one of the at least one synchronization degradation criterion is fulfilled, the radio network node increases the guard period to have an extended duration relative to a previous duration.
