摘要： A base station is capable of performing a method for scheduling in a wireless communication system. In the method, a downlink channel measurement value received from a terminal is compared with a threshold. When the downlink channel measurement value is smaller than the threshold, an activation set for a handover of the terminal is determined. When the number of base stations inside the activation set is two or more, a Modulation and Coding Scheme (MCS) level is allocated to the terminal with consideration of the downlink channel measurement value. A wireless resource is allocated to the terminal with consideration of the allocated MCS level and a headroom of the terminal.
