Wireless communication handover responsive to uplink interference at a serving cell
A wireless communication network hands-over wireless User Equipment (UE) from a serving cell to a neighbor cell. The serving cell wirelessly exchanges data with the wireless UE and determines uplink interference for a radio band. The serving cell wirelessly transfers an uplink interference offset to the wireless UE that indicates the uplink interference at the serving cell for the radio band. The wireless UE uses the uplink interference offset to trigger a handover request to the serving cell. The handover request indicates downlink signal strength at the wireless UE for the serving cell. The serving cell initiates a handover to a neighbor cell responsive to a combination of the downlink signal strength at the wireless UE and the uplink interference for the serving cell falling below a handover threshold. After the handover, the neighbor cell wirelessly exchanges data with the wireless UE over a different radio band.
