Title:
RADIO FREQUENCY SYSTEM AND COMMUNICATION DEVICE
Document Type and Number:
WIPO Patent Application WO/2023/098110
Kind Code:
A1
Abstract:
The present application relates to a radio frequency system and a communication device. The radio frequency system comprises: a radio frequency transceiver (10); a radio frequency transceiving module (20) that is connected to the radio frequency transceiver (10), provided with a first antenna port and a second antenna port, and used for supporting the reception of a low-frequency signal by means of the first antenna port and the second antenna port; and a radio frequency receiving module (30) that is connected to the radio frequency transceiver (10), provided with a third antenna port and a fourth antenna port, and used for supporting the reception of the low-frequency signal by means of the third antenna port and the fourth antenna port. At least two ports among the first antenna port, the second antenna port, the third antenna port, and the fourth antenna port are configured to be switchably connected to at least two antennas of an antenna group, and the at least two ports comprise the first antenna port. The radio frequency system can realize 4*4 MIMO reception of the low-frequency signal; when the radio frequency system is applied to a communication device, a download rate can be increased to improve the user experience, and when the communication device is located at the edge of a cell, in a deep portion of a building, in an elevator and other weak signal environments, the radio frequency system has good reception performance by means of 4*4 MIMO reception.
