Abstract
Systems and methods for performing UE handover based on group delay variation include a base station (i) selecting a target neighbor sector from a plurality of neighbor sectors for the handover, where each neighbor sector has a group delay metric, and where the target neighbor sector is selected from the neighbor sectors based at least in part on each neighbor sector's group delay variation and (ii) initiating handover of the UE to the target neighbor sector. Some embodiments include creating a neighbor relations table (NRT) comprising at least some of the neighbor sectors, and prioritizing the NRT based on group delay and/or group delay variation. In some embodiments, selection of the target neighbor sector for the handover is additionally based on neighbor sector handover success rates and Reference Signal Receive Power (RSRP) values for neighbor sectors reported by the UE for which the handover is to be performed.
