Abstract

The embodiment of the invention provides an uplink signal transmission method and device. The method comprises the steps that network equipment determines physical resources used for transmitting uplink control signals in a time domain scheduling unit; and the network equipment receives the uplink control signal on the physical resource used for transmitting the uplink control signal, wherein the uplink control signal is transmitted by using a cyclic prefix-orthogonal frequency division multiplexing (CP-OFDM) waveform. In the embodiment of the invention, the uplink control signal is transmitted by using the CP-OFDM waveform, and continuous or discontinuous physical resources on the frequency domain can be configured for the uplink control signal by using the multi-carrier transmission characteristic, so that the problem that in the prior art, when the uplink control signal is subjected to uplink transmission by using a single carrier, the uplink control signal must be mapped on the physical resource with continuous frequency domain, so that the flexibility of configuring the physical resource for the uplink control signal is improved.

Description

[0001] This application is a divisional application of the PCT international patent application PCT / CN2016 / 106154 with the filing date of November 16, 2016, which entered the Chinese national phase with the Chinese patent application number 201680090607.0, and the title of the invention is "Transmission method and device for uplink signals". technical field [0002] The embodiments of the present invention relate to the communication field, and more specifically, to a method and device for transmitting an uplink signal. Background technique [0003] In the current LTE communication system, the uplink transmission adopts a single-carrier transmission mode, mainly through the Discrete Fourier Transform-Spreading-Frequency Division Multiple Access (DFT-S-FDMA) waveform for uplink transmission. The main feature of the single carrier transmission mode is that the peak to average power ratio (Peak to average power ratio, PAPR) is relatively small. That is to say, when the termina...
