Abstract

The present disclosure provides a transmission power determination method and device, and a transmission demodulation method and device. The transmission power determination method includes: when the sum of the transmission power in the time domain overlapping area is greater than the preset power, according to the following information At least one of them determines the power of the time-domain overlapping area and / or the non-time-domain overlapping area of ​​the transmission: the modulation and coding scheme of the transmission, the resource ratio, the power reduction parameter, and the priority of the transmission. Through the present disclosure, the problem of unbalanced transmission power in the time domain overlapping area and the non-time domain overlapping area in the related art is solved, and the effect of flexibly adjusting the transmission power and improving the power efficiency of the entire transmission is achieved.

Description

technical field [0001] The present disclosure relates to the communication field, and in particular, to a transmission power determination method and device, and a transmission demodulation method and device. Background technique [0002] At present, the new generation of wireless communication (New Radio, referred to as NR) technology, as the fifth generation mobile communication system, needs to support different types of application scenarios, and also needs to support traditional frequency bands, new high frequency bands and beam modes at the same time. Power control Technology poses great challenges. [0003] Power control technology includes not only how to determine the transmission power of a single channel / signal, but also how to share power when multiple channels and signals are sent in parallel. Especially in the case of insufficient power, how to allocate power among multiple channels and signals to ensure that the maximum power limit cannot be exceeded at any t...
