Abstract

The invention provides a transmission power determination method and device and a transmission demodulation method and device. The transmission power determination method comprises the following steps: when the sum of the transmission power of a time domain overlapping region is greater than a preset power, determining the power of the transmission time domain overlapping region and / or a non-timedomain overlapping region according to at least one of the following information: a transmission modulation coding mode, a resource ratio, a power reduction parameter and a transmission priority. According to the method and the device, the problem of unbalanced transmission power of the time domain overlapping region and the non-time domain overlapping region in the prior art is solved, and the effects of flexibly adjusting the transmission power and improving the power efficiency of the whole transmission are 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...
