Title: BEAM SYNCHRONIZATION METHODS FOR BEAMFORMING WIRELESS NETWORKS
Abstract:
Inter-cell coordination to avoid/minimize inter-cell interference in a beamformed mmWave network is proposed to enhance the detection probability of beam pattern indicator. A base station first obtains beacon signal transmission information of neighboring base stations. A plurality of beacon signals are transmitted over a plurality of control beams from the neighboring base stations. The base station then determines beacon signal transmission configuration by coordinating with the neighboring base stations to minimize inter-cell beacon signal interference. Each control beam is configured with a set of periodically allocated resource blocks and a set of beamforming weights. Finally, the base station transmits beacon signals based on the determined beacon signal transmission configuration over the plurality of control beams.
