Abstract

The present invention relates to the field of communication technologies, in particular to an uplink transmission method, a terminal and a base station, which are used to provide a pilot transmission scheme for terminals supporting CP-OFDM waveforms, including: the terminal determines the frequency domain start position of the pilot, and the The above terminal is a terminal that uses CP-OFDM for uplink transmission; according to the comb interval and the determined frequency domain start position, the pilot is mapped on the symbol of the transmission pilot; and the pilot mapped on the symbol is sent to the base station . The embodiment of the present invention provides a scheme for a terminal using CP-OFDM to perform uplink transmission to map pilots on the same symbol in the uplink direction and multiplex transmission pilots. Since the pilots are mapped on symbols with comb intervals, it can Realize mapping multiple pilot sequences of one terminal on one symbol, or map multiple pilot sequences of different terminals on one symbol, realize support for multiple terminals to multiplex transmission pilots, and improve uplink resource utilization.

Description

Technical field [0001] The present invention relates to the field of communication technology, in particular to an uplink transmission method, terminal and base station. Background technique [0002] With the development and change of mobile communication service requirements, organizations such as ITU (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) in uplink transmission, and it can also support CP-OFDM (Cyclic prefix Orthogonal Frequency Division Multiplexing, Cyclic Prefix Orthogonal Frequency Division Multiplexing) waveforms, there is no relevant plan for how to multiplex and transmit different waveforms. [0003] In the LTE (Long Term Evolution, Long Term Evolution) system, the uppe...
