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.

Multi-user multiple-input multiple-output U-MIMO data transmission method and base station

The present disclosure relates to a multi-antenna transmission method in a co-cell network. The co-cell network includes a first cell and a second cell. The first cell corresponds to two physical antennas, and the second cell corresponds to two physical antennas different from the two physical antennas corresponding to the first cell. In one example method, a base station performs four-antenna precoding processing for a scheduled terminal. The four-antenna precoding processing generates four logical antenna port signals. The base station maps the four logical antenna port signals to the four physical antennas. The base station sends, to the terminal, the four logical antenna port signals through the mapped four physical antennas.

A transport block retransmission method and a base station are described. In the method, for first m retransmissions of a transmission block (TB), a closed-loop spatial multiplexing transmit manner for initial transmission of the TB is maintained.
