Methods and apparatus for interference coordinated transmission and reception in wireless networks

摘要

Methods and apparatus for interference coordination to improve transmission and reception performance within wireless networks. In one exemplary embodiment, a wireless transmitter transmits multiple transmissions over a determined time. The receiver receives the multiple transmissions and attempts to recover the transmitted signal. Because, the fading channel varies over time for each transmitter-receiver, by combining the received signals over multiple iterations, the signal of interest will be magnified, whereas interference effects will be suppressed.

主权项

1. A method of interference management at a wireless device that includes a plurality of receive antennas, the method comprising:
at the wireless device:
receiving a plurality of receive signals through a receive antenna of the plurality of receive antennas, the plurality of receive signals corresponding to a set of up to a pre-determined number of redundant transmissions of a transmit signal sent from a transmit antenna of a plurality of transmit antennas, wherein at least one transmission in the set of redundant transmissions of the transmit signal is shaped by a shaping factor, and wherein the plurality of receive signals include interference signals corresponding to simultaneous transmissions from other transmit antennas in the plurality of transmit antennas; anddecoding the transmit signal by jointly processing the plurality of receive signals using the shaping factor.
