METHOD AND BASE STATION FOR HANDOVER CONTROL IN A HETEROGENOUS NETWORK HAVING CELL LAYERS WITH DIFFERENT, I.E. SYMMETRIC AND ASYMMETRIC, UPLINK (UL) AND DOWNLINK (DL) RESOURCE ALLOCATIONS

摘要

A base station (BS) and method for controlling handover in a wireless communication system. The BS serves a first cell in a first cell layer overlapping with a second cell layer, and the first cell has a different distribution of configured amounts of uplink and downlink resources than a second cell in the second cell layer. The BS monitors amounts of uplink and downlink resources utilized by a user equipment (UE) in the first cell and adjusts at least one parameter controlling handover of the UE to the second cell based on the resources utilized by the UE, and on information regarding configured amounts of uplink and downlink resources in the first and second cells. This increases the likelihood that the UE will be served by one of the first and second cells in which the configured amounts of resources better matches the amounts of resources utilized by the UE.
