OFDMA CELLULAR NETWORK AND METHOD FOR MITIGATING INTERFERENCE
First Claim
1. A base station configured to mitigate uplink interference in an orthogonal frequency division multiple access (OFDMA) cellular network, the base station comprising a scheduler configured to:
- assign a common group identifier (ID) to mobile stations based on interference levels of a common interference source; and
allocate bandwidth within a selected zone of an OFDMA uplink subframe to the mobile stations assigned the common group ID for uplink communications with the base station within the uplink subframe.

Abstract
Embodiments of an OFDMA cellular network and method for mitigating interference are generally described herein. In some embodiments, the scheduler assigns a common group ID to mobile stations based on interference levels of a common interference source and allocates bandwidth within a selected zone of an OFDMA uplink subframe to the mobile stations assigned the common group ID for uplink communications within the uplink subframe. In some joint-scheduling embodiments, a neighbor base station that is identified as the common interference source may refrain from assigning bandwidth within the selected zone to at least some of its associated mobile stations that have identified the serving base station as an interference source.
