Title:
POWER CONTROL METHOD AND APPARATUS
Document Type and Number:
WIPO Patent Application WO/2019/154088
Kind Code:
A1
Abstract:
Embodiments of the present invention provide a method and apparatus for determining transmit power. In the method and apparatus, a terminal device measures, on the basis of one or more beam directions, a signal sent by a network device, so as to obtain one or more measurement results, the beam direction comprising a beam direction used by the terminal device on a side link and further comprising a beam direction used by the terminal device on a cellular link. The terminal device determines a power control parameter, the power control parameter being determined on the basis of the one or more measurement results, and adjusts side link transmit power according to the power control parameter. The terminal device reports the one or more measurement results to the network device, and the network device determines the power control parameter on the basis of the measurement results and sends the power control parameter to the terminal device, so that the terminal device adjusts the side link transmit power according to the power control parameter. Therefore, the side link transmit power is controlled more accurately and the interference from side link communication to the network device is reduced.
