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.

1. A method in a first base station of a wireless communications system for controlling handover, the first base station serving a first cell in a first cell layer overlapping with a second cell layer, wherein 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 method comprising:
monitoring amounts of uplink and downlink resources utilized by a first user equipment in the first cell; and adjusting at least one parameter controlling a handover of the first user equipment to the second cell in the second cell layer, based on the monitored amounts of uplink and downlink resources utilized by the first user equipment, and on information regarding configured amounts of uplink and downlink resources in the first cell and the second cell, respectively, to increase a likelihood that the first user equipment will be served by one of the first or second cells in which the configured amounts of uplink and downlink resources better matches the monitored amounts of uplink and downlink resources utilized by the first user equipment.
