Claim of US Patent No. 10,973,043

1. A method, comprising:determining, by a network device, according to a first current service corresponding to a first terminal device, according to a second current service corresponding to a second terminal device, and according to a preset mapping relationship between a service and a latency level, that a first latency requirement of the first current service is higher than a second latency requirement of the second current service;
receiving, by the first terminal device, according to the determination that the first latency requirement is higher than the second latency requirement, a first downlink control channel that is sent by the network device on a third time-frequency resource; and
after receiving the first downlink control channel:
sending, by the first terminal device, a first uplink message to the network device on a first time-frequency resource based on the first downlink control channel, wherein transmission directions of the first uplink message and a second downlink message are different, the second downlink message is sent by the network device, and the network device schedules, using a second downlink control channel, the second terminal device to receive the second downlink message on a second time-frequency resource; or
receiving, by the first terminal device based on the first downlink control channel and on the first time-frequency resource, a first downlink message sent by the network device, wherein transmission directions of the first downlink message and a second uplink message are different, and the network device schedules, using the second downlink control channel, the second terminal device to send the second uplink message to the network device on the second time-frequency resource;
wherein the first time-frequency resource and the second time-frequency resource comprise a same time domain resource and a same frequency domain resource.
