Abstract: Embodiments provide a uplink channel transmission method. Scheduling information from the network device can be received by a terminal device. The scheduling information indicates uplink time-frequency resources carrying at least one uplink channel. a first uplink channel is carried on a first uplink time-frequency resource, and the first uplink time-frequency resource occupies M subbands in the N subbands in frequency domain, M≥2. The M subbands can be detected by the terminal device to determine, from the first uplink time-frequency resource, a second uplink time-frequency resource usable by the terminal device. The second uplink time-frequency resource occupies K subbands in the M subbands in frequency domain, and M>K≥1. The first uplink channel can be sent by the terminal device by using the second uplink time-frequency resource.
