Abstract: Embodiments of this application disclose a communication apparatus, and relate to the communication field. The communication apparatus specifically includes a first antenna group and a second antenna group. A quantity of element units in the second antenna group is greater than a quantity of element units in the first antenna group. The first antenna group is connected to a first radio frequency channel, and the second antenna group is connected to a second radio frequency channel. The first antenna group may be driven using a first radio frequency channel group to meet a requirement for an antenna coverage capability of a base station. The second antenna group is driven using a second radio frequency channel group to meet a beamforming requirement of a traffic channel of the base station.

Abstract: This application provides a radio broadcast beam coverage enhancement method and apparatus. In some embodiments, the method includes: a base station determines at least one target traffic beam, where in an area covered by the at least one target traffic beam, data channel quality of at least one terminal is higher than a first threshold, and broadcast channel quality is lower than a second threshold. The base station transmits N first SSB beams in at least one BWP, where the N first SSB beams cover the area covered by the at least one target traffic beam, and N is an integer greater than or equal to 1. According to the foregoing method in this application, the at least one BWP can be configured for the area covered by the target traffic beam, to enhance an SSB signal in the area, so that the terminal can access a cell.
