ABSTRACT:
Embodiments include methods performed in time division duplex (TDD) radio communication systems in which information is communicated between a first node (e.g., a base) and a second node (e.g., user equipment) in a context of a data frame that includes a plurality of slots. The second node applies an adjustment to an alignment between a second node transmit clock and a second node receive clock based on a propagation delay between the first node and the second node. The adjusted alignment ensures that second node receive slots and second node transmit slots are non-overlapping with each other in time, and that the second node will operate in a half-duplex mode of operation. The second node transmits a transmit burst during the second node transmit slots, and receives a first node transmit burst from the first node during the second node receive slots.
