Apparatus and method for dynamic frequency assignment in a wireless communication system

摘要

An apparatus and method for dynamic frequency assignment to a low-power Base Station (BS) in a wireless communication system are provided. The method includes receiving a Received Signal Strength Indication (RSSI) measurement result for the whole Frequency Assignment (FA) and an available FA set of the BS from the BS newly entering a network, selecting an FA having a minimum RSSI among FAs included in the available FA set, and assigning the FA having the minimum RSSI to the BS.

1. A method for assigning a frequency to a Base Station (BS) in a BS management server of a wireless communication system, the method comprising:
requesting, via a message sent from the BS management server, the BS newly entering a network to transmit a Received Signal Strength Indication (RSSI) measurement result for a whole Frequency Assignment (FA) and an available FA set of the BS after the BS management server has detected the BS newly entering the network; receiving the RSSI measurement result for the whole FA and the available FA set of the BS from the BS newly entering the network after the BS newly entering the network has received the message from the BS management server; selecting an FA having a minimum RSSI among FAs included in the available FA set; and assigning the FA having the minimum RSSI to the BS, wherein the available FA set comprises at least one FA having a relatively lower maximum received power from among the whole FA.
