Title:
TERMINAL DEVICE, SIGNAL TRANSMISSION METHOD AND BASEBAND CHIP
Document Type and Number:
WIPO Patent Application WO/2021/258788
Kind Code:
A1
Abstract:
The present application provides a terminal device, a signal transmission method and a baseband chip. The terminal device comprises: a radio frequency transceiver chip, a first antenna system and a second antenna system connected to the radio frequency transceiver chip, and a baseband chip connected to the radio frequency transceiver chip. When a signal is sent to a network device, the signal is sent to the network device in a first direction by means of the first antenna system, and the first antenna system is used for sending a signal in the first direction; and when a signal of the network device is received, the signal from the network device is received in all directions by means of the second antenna system, and the second antenna system is used for receiving a signal in all directions. A signal is sent in a first direction by means of the first antenna system and a signal is received in all directions by means of the second antenna system, ensuring that both an uplink and a downlink can obtain optimal performance, and solving various negative problems caused by increasing the strength of an uplink signal in the prior art.
