Title:
UPLINK TRANSMISSION METHOD, TERMINAL, AND BASE STATION
Document Type and Number:
WIPO Patent Application WO/2018/127213
Kind Code:
A1
Abstract:
The present invention relates to the technical field of communications, and specifically relates to an uplink transmission method, terminal, and base station, used for providing a pilot frequency transmission solution for a terminal supporting an CP-OFDM waveform, and comprising: a terminal determines a frequency domain starting position of a pilot frequency, the terminal being a terminal using CP-OFDM to perform uplink transmission; on the basis of a comb-type interval and the determined frequency domain starting position, mapping the pilot frequency onto a transmission pilot frequency symbol; and sending the pilot frequency mapped onto the symbol to a base station. The embodiments of the present invention provide a solution for a terminal using CP-OFDM for uplink transmission to map a pilot frequency and a multiplexing transmission pilot frequency onto the same symbol in the uplink direction; as a comb-type interval is used to map the pilot frequency onto the symbol, multiple pilot frequency sequences of one terminal can be mapped onto one symbol, or multiple pilot frequency sequences of different terminals can be mapped onto one symbol, thus supporting multi-terminal multiplexing transmission pilot frequencies, and improving uplink resource utilisation.
