Abstract: A data transmission method and apparatus. The method includes: determining a second weight matrix based on a first weight matrix indicated by a first PMI fed back by a terminal, and then converting the second weight matrix into a non-equal power weight matrix based on a non-equal coefficient matrix, so that a network device can send data with non-equal power on different radio frequency channels. This improves power utilization, implements a better beam side lobe, better mitigates a performance loss caused by inaccurate channel information, and improves data transmission quality.

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: Embodiments of this application provide antenna switching methods and apparatuses. In an implementation, a first communication device determines a first antenna identifier based on air interface transmission information, the first communication device sends the first antenna identifier to a digital switch, and the digital switch switches from a second switch state to a first switch state based on the first antenna identifier, where the first switch state indicates that a second communication device communicates with the first antenna within a first time unit, and the second switch state indicates that the second communication device communicates with a second antenna within a second time unit.
