Title:
SIDELINK POWER CONTROL METHOD AND TERMINAL
Document Type and Number:
WIPO Patent Application WO/2020/143632
Kind Code:
A1
Abstract:
Embodiments of the present application provide a sidelink power control method and a terminal, pertaining to the field of wireless communications, and providing a power sharing method to a terminal sending information via a first transmission link and a second transmission link, such that a transmission power sum of the first transmission link and the second transmission link for sidelink transmission is controlled to not exceed a maximum transmission power of the terminal. The method comprises: acquiring a first maximum transmission power and a second maximum transmission power; if a terminal determines to send first information via a first transmission link and second information via a second transmission link in a frequency-division multiplexing mode, calculating a first actual power and a second actual power according to the first maximum transmission power and the second maximum transmission power; and if a sum of the first actual power and the second actual power is greater than a first power threshold, determining a first final power and a second final power according to the first actual power and the second actual power.
