Patent ID: 8526407

Claim:
A method of mitigating interference between Coordinated Multi-Point (CoMP) cells by a first CoMP cell controller managing transmissions in a plurality of sub-cells comprising a first CoMP cell, comprising: receiving, from a second CoMP cell controller managing transmissions in a second, neighboring CoMP cell, information identifying a User Equipment (UE) in the second CoMP cell scheduled to receive transmissions from the second CoMP cell during a predetermined transmission duration, the UE in the second CoMP cell also receiving interference from one or more antennas of the first CoMP cell, wherein the UE in the second CoMP cell is in a border sub-cell of the second CoMP cell, wherein such border sub-cell borders the first CoMP cell; obtaining information about the downlink channel to the UE in the second CoMP cell; and scheduling transmissions, prior to the commencement of the predetermined transmission duration, to a plurality of UEs in the first CoMP cell to maximize data rates, subject to the constraint that interference to the UE in the second CoMP cell, due to the transmissions, is below a predetermined level.
