Abstract

The invention discloses a power distribution method, a power adjustment method, a terminal and an access network device, and belongs to the technical field of communication. The method comprises the following steps: determining, by the terminal, a first initial transmitting power and second initial transmitting power; receiving minimum guaranteed power information of a channel carried by a first carrier and sent by an access network device; and when the sum of any initial transmitting power in the first initial transmitting power and the second initial transmitting power is greater than the maximum transmitting power, obtaining available transmitting power of the channel carried by the first carrier in N first sub-frames and the available transmitting power of the channel carried by a second carrier in a second sub-frame according to the priority sequence of the channel carried by the first carrier in N first sub-frames and the channel carried by the second carrier in the second sub-frame, wherein the second carrier is overlapped with the N first sub-frames, and M first sub-frames are previous M first sub-frames in the N first sub-frames.

Description

technical field [0001] The present invention relates to the technical field of communication, and in particular to a power allocation method, a power adjustment method, a terminal and an access network device. Background technique [0002] The Long Term Evolution–Advanced (LTE-A for short) system is a further development of the Long Term Evolution (LTE for short) system of the 3rd Generation Partnership Project (3GPP for short). Evolve and enhance the system. In the LTE-A system, in order to meet the peak data rate requirements of the International Telecommunication Union for the fourth-generation communication technology, the Carrier Aggregation (CA) technology is introduced, also known as the Spectrum Aggregation technology or bandwidth extension. (Bandwidth Extension) technology. In carrier aggregation, spectrums of two or more component carriers (Component Carriers) are aggregated together to obtain a wider transmission bandwidth. [0003] In the carrier aggregation s...
