Abstract

The invention relates to the technical field of communication and particularly relates to an uplink transmission method, a terminal and a base station. A pilot transmission scheme is provided for a terminal supporting a CP-OFDM (Cyclic prefix Orthogonal Frequency Division Multiplexing) waveform. The method comprises the steps that the terminal determines a frequency domain initial position of pilots, wherein the terminal is the terminal which carries out uplink transmission through the CP-OFDM; mapping pilots on a symbol of a transmission pilot according to comb spacing and the determined frequency domain initial position; and sending the pilots mapped on the symbol to the base station. The embodiment of the invention provides the scheme of mapping the pilots and multiplexing the transmission pilot on the same symbol in an uplink direction by the terminal which carries out the uplink transmission through the CP-OFDM. The pilots are mapped on the symbol through adoption of the comb spacing, a plurality of pilot sequences of the terminal can be mapped on the same symbol, or the plurality of pilot sequences of different terminals can be mapped on the same symbol, the fact that a plurality of terminals multiplex the transmission pilot can be realized. An uplink resource utilization rate can be improved.

Description

technical field [0001] The present invention relates to the technical field of communication, and in particular to an uplink transmission method, a terminal and a base station. Background technique [0002] With the development and change of mobile communication service requirements, organizations such as ITU (International Telecommunication Union, International Telecommunication Union) and 3GPP have begun to study new wireless communication systems (such as 5G systems). The new wireless communication system can support DFT-S-OFDM (discrete Fourier transform spread Orthogonal Frequency Division Multiplexing, Orthogonal Frequency Division Multiplexing based on Fourier transform extension) and CP-OFDM (Cyclic prefix Orthogonal Frequency Division Multiplexing) in uplink transmission. Frequency Division Multiplexing, cyclic prefix orthogonal frequency division multiplexing) waveform, how to multiplex and transmit different waveforms has no related scheme. [0003] In an LTE (Lo...
