Title:
RADIO-FREQUENCY CIRCUIT, TERMINAL DEVICE CONTROL METHOD, TERMINAL DEVICE, AND STORAGE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2023/061001
Kind Code:
A1
Abstract:
Embodiments of the present application relate to the technical field of antennas, and provide a radio-frequency circuit, a terminal device control method, a terminal device, and a storage medium. The radio-frequency circuit (100) comprises: an antenna group (10) that at least comprises a first antenna (11) and a second antenna (12); a switch circuit (20) that is connected to the first antenna (11); a signal flow direction control circuit (30) that is connected to the second antenna (12); a power distribution module (40) that is connected to the signal flow direction control circuit (30) and the switch circuit (20); and a radio-frequency transceiving module (50) that is connected to the switch circuit (20) and the signal flow direction control circuit (30), wherein when it is detected that an SAR value of any one of the antennas (11, 12) in the antenna group (10) exceeds a standard threshold, the power distribution module (40) adjusts the transmission power of the first antenna (11) and the second antenna (12).
