Abstract

The invention provides a downlink power allocation indication method, a downlink power allocation determination method, a terminal and network side equipment and belongs to the technical field of wireless communication, the downlink power allocation indication method comprises the following steps: sending indication information to a terminal, the indication information at least comprising first indication information and second indication information, so that the terminal can determine the power of a first PDSCH RE according to the first indication information and determine the power of a second PDSCH RE according to the second indication information; one of the first PDSCH RE and the second PDSCH RE is a PDSCH RE with the same symbol as the CSI-RS, and the other one of the first PDSCH REand the second PDSCH RE is a PDSCH RE with a different symbol from the CSI-RS. Waste of system power resources can be reduced, and system performance is improved.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, in particular to a downlink power allocation indication method, determination method, terminal and network side equipment. Background technique [0002] For the 5G NR (5th-Generation New Radio, fifth-generation mobile communication technology-new air interface) system, the downlink power allocation in the current protocol is very flexible. The difference from 4G (the 4th Generation mobile communication technology, the fourth generation mobile communication technology) is that 5G power is no longer allocated in the full bandwidth, but can be randomly and flexibly allocated, so the protocol only defines the power comparison of each signal. [0003] For example, for the determination of PDSCH (Physical Downlink Shared CHannel, physical downlink shared channel) EPRE (Energy Per RE, energy on each RE (Resource Element, resource element)). The network side first notifies the ter...
