摘要： The present disclosure discloses example broadcast beam processing methods and apparatuses. One example method includes sending a first broadcast beam. A first measurement report is received from a first terminal after the first broadcast beam is sent, and a weak coverage area of the first broadcast beam is determined based on the first measurement report. A second broadcast beam is then sent, where the second broadcast beam is used to cover the weak coverage area of the first broadcast beam.

摘要： This application provides a method for adjusting a half-power angle of an antenna, to adjust a maximum half-power angle or a maximum beam gain of an individual transceiver channel. The method includes: first determining that M antenna elements in N antenna elements connected to a first transceiver channel of an access network device need to be turned on or off, where N>M≥1, and both N and M are integers, that is, a quantity of antenna elements driven by the first transceiver channel needs to be adjusted; and then sending first indication information to the access network device, where the first indication information is used to indicate to turn on or off the M antenna elements.

摘要： A resource scheduling method and a related device configure a scheduled resource for a terminal device based on a dynamic analog beam determined by a network device, thereby increasing a throughput of the terminal device. The network device determines, based on information about an SRS of each first terminal device, a set of second terminal devices from a set of first terminal devices and static analog beam information of each second terminal device in the set of second terminal devices. Then, the network device determines beam domain channel information based on the static analog beam information. As such, the network device determines dynamic analog beam information of each second terminal device based on the static analog beam information and the beam domain channel information.

摘要： A measurement method, a terminal device, and a network device are described. The measurement operation includes sending a channel state information-reference signal CSI-RS measurement beam to a terminal device. The CSI-RS measurement beam is obtained by the network device by weighting a CSI-RS by using a beamforming weight, and the beamforming weight is used to perform beamforming on the CSI-RS. The measurement operation further includes receiving a rank indicator and a channel quality indicator that are determined based on the CSI-RS measurement beam. The measurement operation further includes weighting and transmitting a downlink channel based on the rank indicator and the channel quality indicator. The CSI-RS is weighted and transmitted by using the beamforming weight, to help improve accuracy of rank measurement, thereby improving a user throughput.
