ADJUSTING RECEIVE-TRANSMIT TIMING TO COMPENSATE FOR SWITCHING ERRORS IN A COMMUNICATION SYSTEM

摘要

Techniques for compensating for the time misalignment of receive-transmit switching in a multi- antenna radio network node are disclosed. An example method begins with the detection (1020) of signal transmission timing for each of two or more antennas associated with the radio network node, for at least a first transmission period. Next, the radio network node determines (1030) that transmit timing for at least one of the antennas is misaligned by at least a first threshold time interval, based on the detected signal transmission timings. The example method continues with the adjustment (1040) of transmit timing for at least one of the antennas for one or more subsequent transmission periods, responsive to determining that the transmission timing for at least one of the antennas is misaligned.
