AI Technical Summary

Technical Problem

In communication, when multiple terminals share TR resources, the resultant neighbour zone homofrequency interference and the temporary frequency interference in this zone are difficult to effectively control, especially in signal transmission with a larger peak-to-average power ratio (PAPR), the high power of the transmitter end Amplifiers (HPAs) are easily entered into nonlinear regions and cause interference.

Method used

The transmission power of the terminal on the shared TR resource is controlled by the network device, and the upper limit of the transmission power of the terminal in the overlapping area is limited to reduce interference caused by the peak-cut waveform when multiple terminals share the TR resource. The specific method includes sending indicative information to the terminal, determining its total transmission power upper limit value on the TR resource or the transmission power upper limit value of each resource unit, thereby avoiding excessive power superposition.

Benefits of technology

It effectively reduces the adjacent area syn-frequency interference and the temporary frequency interference of this area caused by multiple terminals to send peak-cut waveforms on shared TR resources, improves the terminal coverage performance, and avoids the problem of excessive power superposition of the cancellation waveform.

Abstract

The invention relates to the technical field of communication, and discloses a communication method and device. The method comprises: after determining that a first TR resource of a first terminal and a second TR resource of a second terminal overlap, a network device sends first information to the first terminal, the first information being used for determining the sending power of the first terminal on the overlapped TR resource. By adopting the method, the network equipment can limit the sending power of the first terminal on the overlapped TR resources through the first information, so that the terminal coverage can be improved, and the same-frequency interference of the adjacent region and the adjacent-frequency interference of the local region caused by the fact that a plurality of terminals send peak clipping waveforms on the shared TR resources can be reduced.
