Abstract
The present application provides a method for a terminal device to transmit uplink service data to a base station. The terminal device obtains uplink service data from a user input in a service session. The terminal device obtains a codebook from a preset codebook set of the terminal and a pilot sequence corresponding to the codebook. The terminal device generates an uplink data signal according to the codebook and the uplink service data, and generates a pilot signal corresponding to the pilot sequence. The terminal device transmits the uplink data signal and the pilot signal to the base station.
