Abstract: A communication method, apparatus, and system are provided. The method may be performed by a first network device, or may be performed by a component (for example, a processor, a chip, or a chip system) of the first network device. In one example method, the first network device determines that a terminal device is to enter a first area, where the first area is an area in which the terminal device is handed over from the first network device to a second network device, or the first area is an area in which the first network device and the second network device perform joint transmission; and the first network device sends first indication information to the terminal device before the terminal device enters the first area, where the first indication information indicates to measure a first tracking reference signal of the second network device.

Abstract: Embodiments of this application disclose a resource scheduling method and a related device, to 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 method in embodiments of this application includes: 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. Therefore, 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.

Abstract: 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.

Abstract: The present disclosure relates to a radio resource scheduling method and apparatus. When a sending end receives a NACK message fed back by a receiving end, the method includes acquiring, by the sending end, data whose response message is the NACK message as data to be retransmitted, where the data to be retransmitted includes at least one transport block; and determining, by the sending end according to a RLC status report sent by the receiving end, whether the receiving end successfully receives each transport block of the data to be retransmitted. If all the transport blocks of the data to be retransmitted are successfully received, canceling retransmission of the data to be retransmitted; or if not all the transport blocks of the data to be retransmitted are successfully received, retransmitting a transport block that is in the data to be retransmitted and is not successfully received.

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: 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.

Abstract: 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.
