APPARATUS AND METHOD FOR CONTROLLING UPLINK POWER IN A WIRELESS COMMUNICATION SYSTEM

摘要

The present invention relates to an apparatus and a method for controlling uplink power by considering interference between the cells based on cooperative transmission in a wireless communication system. Inter-cell cooperation information including resource assignment information and uplink channel information of a wireless terminal located in service areas of respective access nodes is received from the respective access nodes. A transmission power control command for the uplink of the random access node is generated based on the inter-cell cooperation information received from the respective access nodes. Reference inter-cell cooperation information includes the inter-cell cooperation information received from one or more cooperation access nodes for providing the inter-cell cooperation transmission for the specific wireless terminal with a random access node. The generated transmission power control command or the included reference inter-cell cooperation information is transmitted to the random access node. During this time, the random access node and one or more cooperative access nodes are included in the access nodes.
