Method and apparatus for power control and interference coordination

摘要

An exemplary method of communicating includes a relay node that uses a cell identifier that is also used by a base station having a coverage area within which the relay node is located. The method includes determining that a mobile station is within a communication range of the relay node. A transmission power from the relay node is controlled so that the total transmission power of at least one transmission from the relay node and the base station corresponds to a selected transmit power limit. A timing of a downlink transmission from the base station and the relay node is coordinated based on a schedule determined by the base station. At least one uplink control parameter is set at the base station based upon uplink information regarding a link between the mobile station and the relay node.

1. A method of communicating through a relay node that uses a cell identifier that is also used by a base station having a coverage area within which the relay node is located, comprising the steps of:
(A) determining that a mobile station is within a communication range of the relay node; (B) controlling a transmission power from the relay node so that the total transmission power of at least one transmission from the relay node and the base station corresponds to a selected transmit power limit; (C) coordinating a timing of a downlink transmission from the base station and the relay node based on a schedule determined by the base station; and (D) setting at least one uplink control parameter at the base station based upon uplink information regarding a link between the mobile station and the relay node.
