Abstract: A method, device, and storage medium are disclosed that determine beam information of an antenna port for a frequency domain resource not used for transmitting uplink data and/or uplink control information. In one embodiment, a first device determines, based on first configuration information, that a beam for sending a first uplink reference signal on a first antenna port is also a beam for sending a second uplink reference signal on a second antenna port, and sends the first uplink reference signal on the first antenna port. Beam information of the first antenna port can be determined based on beam information of the second antenna port, and the first uplink reference signal can be sent based on the determined beam information of the first antenna port. This can spare beam configuration performed by a network side for the first frequency domain resource, and reduce overheads for transmitting configuration information.

Abstract: This application provides example communication methods, terminal devices, and network devices. One example method includes configuring, by a network device, a first bandwidth part BP and a second BP for a terminal device. The network device then sends a first TB to the terminal device. When the first BP and the second BP correspond to a same physical parameter, the first TB is mapped onto the first BP and the second BP. When the first BP and the second BP correspond to different physical parameters, the network device further sends a second TB to the terminal device, where the first TB is mapped onto the first BP, and the second TB is mapped onto the second BP.
