Claim of US Patent No. 11,071,135


1. A method for uplink transmission, comprising:determining a first time-frequency resource and a second time-frequency resource allocated by a network device, the first time-frequency resource being used for transmitting an uplink Scheduling Request (SR), and the second time-frequency resource being used for transmitting an uplink reference signal; and
responsive to that uplink data needs to be transmitted to the network device, transmitting the uplink SR to the network device via the first time-frequency resource, and transmitting the uplink reference signal to the network device via the second time-frequency resource, so that the network device determines quality of an uplink channel by using the uplink reference signal.
