NETWORK ASSISTED INTERFERENCE MITIGATION

摘要

A method for network assisted interference mitigation includes identifying at least one pair of adjacent resource blocks within a same subframe. The at least one pair includes a low power resource block (RB) and a high power RB. The low power RB has a substantially lower beamforming gain compared to the high beamforming gain of the high power RB such that a ratio (R) comparing receive powers of the high power RB and the low power RB to each other is greater than a threshold ratio (μ). The method includes reducing a transmit power of the high power RE to a reduced transmit power level at which the ratio R is less than or equal to the threshold ratio μ (R≦μ).

1. A method comprising:
identifying at least one pair of adjacent resource blocks within a same subframe, the at least one pair including a low power resource block (RB) and a high power RB, wherein the low power RB has a substantially lower beamforming gain compared to the high beamforming gain of the high power RB such that a ratio (R) comparing receive powers of the high power RB and the low power RB to each other is greater than a threshold ratio (μ); and reducing a transmit power of the high power RB to a reduced transmit power level at which the ratio R is less than or equal to the threshold ratio μ (R≦μ), and transmitting zero power at REs of the high power RB that are adjacent to the low power RB.
