ABSTRACT:
A method of handling intercell interference applies physical layer (L1) scheduling decisions to ensure that L1hybrid automatic repeat request (H-ARQ) retransmissions will not experience the same interference conditions. The retransmission is scheduled in a sub-frame portion that does not include previously tracked allocations of a plurality of users. Potential intercell interference is also handled by applying a time-shift of the L1H-ARQ retransmissions, such that the bit positions impacted by inter-cell interference will change and thus assure a more robust performance.
