Title:
CARRIER SELECTION METHOD AND CARRIER ADJUSTMENT APPARATUS FOR TDD HOME BASE STATION
Document Type and Number:
WIPO Patent Application WO/2010/045752
Kind Code:
A1
Abstract:
A carrier selection method and a carrier adjustment apparatus for a time division duplex (TDD) home base station are provided. The available uplink/downlink frequency resources of the home base station are divided into multiple frequency bands. The carrier selection method includes the following steps: measuring the received signal strength indicator of each of the multiple frequency bands; integrating the measurement result according to the uplink/downlink performance requirement coefficient that is required by the relevant service, in order to obtain the integrated interference level of each frequency band; combining the multiple frequency bands into several frequency band sets according to the channel bandwidth of the home base station itself, with each frequency band set able to be used to form the uplink/downlink channel of the TDD home base station; computing the integrated performance indicator of every frequency band set based on the integrated interference level of each frequency band in each frequency band set; selecting the frequency band set whose integrated performance indicator satisfies predetermined conditions to form the uplink/downlink channel of the home base station, and in this way adjusting the uplink/downlink channel carrier of the home base station.
