Problems solved by technology

When the radiation caused by the transmit power used by the transmit beam exceeds the MPE limit, it is necessary to limit the transmit power of the beam, for example, to control the transmit power backoff of the beam, which will affect the uplink transmission performance of the terminal

Abstract

The invention relates to a sending power indication and determination method and device, a terminal, equipment and a medium, and belongs to the technical field of communication. The method comprises the following steps: determining the maximum allowable sending power of at least one uplink beam of a terminal, wherein the maximum allowable sending power is the maximum sending power under the condition of meeting the MPE limitation of the terminal; and sending first indication information used for indicating the maximum allowable sending power of at least one uplink beam. The method is beneficial to improving the uplink transmission performance.

Description

technical field [0001] The present disclosure relates to the technical field of communication, and in particular to a method, device, terminal, device and medium for indicating and determining transmission power. Background technique [0002] In 5G new air interface (NR, New Radio) technology, especially when the communication frequency band is in frequency range 2 (Frequency Range 2, FR2), due to the fast attenuation of high-frequency channels, in order to ensure coverage, it is necessary to use beam-based transmission and reception . [0003] In related technologies, when a terminal transmits a beam through an antenna panel, there is a maximum permissible radiation (Maximum Permissible Exposure, MPE) limit to avoid harm to the human body. When the radiation caused by the transmit power used by the transmit beam exceeds the MPE limit, it is necessary to limit the transmit power of the beam, for example, control the transmit power backoff of the beam, which will affect the ...
