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.

Claims20

Dependent claims

An uplink channel transmission method, wherein the method is applied to a communications system comprising a network device and a terminal device, wherein a system frequency domain resource used by the communications system is divided into N subbands and N≥2, the system frequency domain resource being a frequency domain resource used based on a contention mechanism, and the method comprises:

receiving, by the terminal device, scheduling information from the network device, wherein the scheduling information indicates uplink time-frequency resources carrying at least one uplink channel, the uplink time-frequency resources being allocated by the network device to the terminal device, wherein a first uplink time-frequency resource in the uplink time-frequency resources carries a first uplink channel in the at least one uplink channel, and the first uplink time-frequency resource occupies M subbands in the N subbands in frequency domain, N≥M≥2;
detecting, by the terminal device, the M subbands, to determine, from the first uplink time-frequency resource, a second uplink time-frequency resource configured to the terminal device, wherein the second uplink time-frequency resource occupies K subbands in the M subbands in frequency domain, M>K≥1;
and
sending, by the terminal device, the first uplink channel by using the second uplink time-frequency resource.
