Embodiment Construction
[0035] The present invention provides a method for implementing antenna array broadcast channel coverage, that is, by setting multiple sub-beams, and based on the transmission time interval (TTI) or its integer multiples, using multiple sub-beams to switch sequentially or alternately to transmit broadcast channel information, thereby realizing broadcasting channel coverage.
[0036] A method for implementing antenna array broadcast channel coverage in an embodiment of the present invention is as follows, as follows: figure 1 Shown:
[0037] Step 10, based on the coverage of the cell / sector, determine the direction of the broadcast beam of the antenna array and the half power width of the broadcast beam.
[0038] Among them, the direction of the broadcast beam of the antenna array is θ B , the half-power width (beamwidth) of the broadcast beam is Ω B . The gain of the broadcast beam is denoted as ρ B .
[0039] Step 20, centering on the broadcast beam pointing, set N sub-...
