Abstract:
Disclosed are a broadcast information transmission method and device. A base station uses preset beamforming weight vectors to perform beamforming on a physical broadcast channel. A plurality of preset beamforming weight vectors are used and sequentially selected by the base station to perform beamforming on the physical broadcast channel. Since a plurality of preset beamforming weight vectors are used, a coverage effect on a sector is therefore improved in comparison with a single beam. In addition, the preset beamforming weight vectors are sequentially selected by the base station to perform beamforming on the physical broadcast channel, and broadcast information transmitted by the physical broadcast channel therefore achieves effective coverage.

Claim (Index 5):
The method according to  claim 1 , wherein the plurality of preset beam-forming weight vectors are divided into M sets, each set comprises N beam-forming weight vectors, the entire sector is fully covered with beams corresponding to the M*N beam-forming weight vectors, and both M and N are integers more than 1; and\n determining, by the base station, the beam-forming weight vector for beam-forming on the physical broadcast channel comprises: selecting, by the base station, one of the M sets according to a preset first order at a preset first cycle; and selecting, by the base station, one of the beam-forming weight vectors in the selected set according to a preset second order at a preset second cycle, wherein the selected beam-forming weight vector is used to perform beam-forming on the physical broadcast channel in the corresponding second cycle, and the length of the first cycle is no less than N times the length of the second cycle.
