Claim of US Patent No. 10,993,123

1. A method, comprising:determining, by a base station, a first coverage zone that is set to a covered state in a first cell of the base station at a current moment, wherein the first cell of the base station comprises a plurality of coverage zones including the first coverage zone, there is at least one coverage zone of the plurality of coverage zones set to the covered state in the first cell at any given moment, and coverage zones set to the covered state in the first cell at different moments are different, and wherein the at least one coverage zone of the plurality of coverage zones comprises a perimeter that defines the at least one coverage zone, wherein a portion of the perimeter that is closest to the base station is physically separate from and does not touch the base station;
performing, by the base station, beamforming on data carried by a common channel to obtain a common channel beam of the first cell at the current moment, wherein the common channel beam of the first cell at the current moment points to the first coverage zone that is set to the covered state in the first cell at the current moment, wherein the common channel beam excludes a rotary narrow beam that rotates around the base station at a preset radian rate, and wherein the first coverage zone to which the common channel beam points at the current moment does not overlap with any other zone of the plurality of coverage zones in the first cell of the base station; and
sending, by the base station, the common channel beam of the first cell at the current moment to the first coverage zone that is set to the covered state in the first cell at the current moment.
