AI Technical Summary

Technical Problem

During signal transmission, the nonlinear distortion of the power amplifier leads to a reduction in communication capacity. Although frequency domain spectrum shaping reduces the peak-to-average power ratio, it also reduces the subcarrier energy at the edge of the signal transmission bandwidth, affecting data demodulation performance.

Method used

By adjusting the sequence spread factor and frequency domain spectral shaping, the transmission bandwidth and redundant data volume are dynamically adjusted while keeping the communication OBO gain and PAPR gain constant, thereby increasing the communication capacity.

Benefits of technology

Without changing OBO and PAPR, the data transmission capacity of the communication system is improved and the spectrum utilization efficiency of the signal is optimized.

Abstract

A resource configuration method and device. The method comprises: a terminal device receives configuration information from a network device, wherein the configuration information is used for configuring a transmission bandwidth of a waveform for the terminal device, so that the terminal device can transmit data with the network device on the basis of the transmission bandwidth. The transmission bandwidth is determined on the basis of a sequence spreading factor, the sequence spreading factor is a preset value, and the waveform generation comprises performing, on the basis of the sequence spreading factor, sequence spreading and frequency-domain spectral shaping (FDSS) on a symbol sequence carried by the waveform. A transmission bandwidth is allocated to a terminal device by means of a sequence spreading factor, so as to ensure the communication capacity or increase the communication capacity on the basis of a given sequence spreading factor (i.e., on the basis of ensuring the OBO gain and PAPR gain).
