Beamforming using predefined spatial mapping matrices

摘要

In one or more aspects data packets are iteratively transmitted to a receiver using predefined spatial mapping matrices, channel estimates are received from the receiver responsive to iteratively transmitted data packets, and one of the predefined spatial mapping matrices is selected for transmitting additional data packets to the receiver based on the received channel estimates.

1. A method comprising:
storing, in a memory, predefined spatial mapping matrices useful for transmitting data packets to a receiver; iteratively transmitting one or more of the data packets to the receiver, each act of transmitting using a different one of the predefined spatial mapping matrices stored in the memory; receiving, from the receiver, channel estimates responsive to iteratively transmitting the one or more data packets; selecting, based on the received channel estimates, one of the predefined spatial mapping matrices stored in the memory for use in transmitting one or more additional data packets to the receiver; and selecting another one of the predefined spatial mapping matrices when a reception quality metric associated with the one or more additional data packets transmitted to the receiver fails to meet a reception quality metric threshold.
