Problems solved by technology

[0003] An embodiment of the present invention provides a transmission method and a first communication device to solve the problem that the existing DMRS sequence is generated by using a ZC sequence or a PN sequence, which causes the PAPR of the DMRS symbol to be higher than the PAPR of the data symbol, resulting in poor uplink coverage performance.

Abstract

The invention provides a transmission method and first communication equipment, and the method comprises the steps that the first communication equipment transmits a target reference signal of a first-type reference signal under the condition that the first communication equipment receives indication information transmitted by second communication equipment and the indication information indicatesthe transmission of the first-type reference signal; wherein the reference signal sequence of the first type reference signal is generated based on a first characteristic. Thus, compared with the prior art, the PAPR of the target reference signal transmitted by the embodiment of the invention is relatively low, so that the power amplification efficiency of the signal transmitting end can be improved, the power consumption can be reduced, the demodulation performance of the signal receiving end can be improved, and the uplink coverage can be improved.

Description

technical field [0001] The embodiments of the present invention relate to the field of communication technologies, and in particular, to a transmission method and a first communication device. Background technique [0002] In the existing NR (New Radio, new air interface) mobile communication system, when PUSCH (Physical Uplink Shared Channel, physical uplink shared channel) or PUCCH (Physical Uplink Control Channel, physical uplink control channel) adopts transmission precoding (also called DFT- s-OFDM waveform), the DMRS (Demodulation Reference Signal, demodulation reference signal) sequence is generated by a low PAPR (Peak-to-Average Power Ratio, peak-to-average power ratio) sequence (also known as ZC sequence) or PN sequence, resulting in The PAPR of DMRS symbols is higher than that of data symbols, resulting in poor uplink coverage performance. Contents of the invention [0003] Embodiments of the present invention provide a transmission method and a first communicat...
