Title:

BROADCAST INFORMATION TRANSMISSION METHOD AND DEVICE

Document Type and Number:

WIPO Patent Application WO/2017/114516

Kind Code:

A1

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.
