Problems solved by technology

[0004] While the transmitter of the terminal device is transmitting signals, if the receiver is receiving signals at the same time, and the signal transmitted by the terminal device is at the same frequency as the received signal, the signal transmitted by the terminal device will interfere with the same frequency signal received by the terminal device. This phenomenon can be called self-interference, and the generation of self-interference will cause the decline of communication performance

Abstract

Embodiments of the present application provide a wireless communication method and device, which can avoid self-interference of terminal devices as much as possible, and improve performance of a communication system. The method includes: the terminal device determines that the first signal and the second signal cause self-interference or have the possibility of self-interference to the terminal device, wherein the first signal is used between the terminal device and the first network device The signal transmitted by the first carrier, the second signal is a signal transmitted between the terminal device and the second network device by using the second carrier; the terminal device sends the first information to the first network device, and the The first information is used to indicate that the first signal and the second signal cause self-interference to the terminal device or have the possibility of self-interference, and indicate that the terminal device and the second network device use A situation where the second carrier performs signal transmission.

Description

[0001] Cross References to Related Applications [0002] This application claims the priority of the PCT patent application with application number PCT / CN2017 / 089687 and titled "Wireless Communication Method and Device" filed with China Patent Office on June 23, 2017, the entire contents of which are hereby incorporated by reference. technical field [0003] The present application relates to the communication field, and more particularly, to a wireless communication method and device. Background technique [0004] While the transmitter of the terminal device is transmitting signals, if the receiver is receiving signals at the same time, and the signal transmitted by the terminal device is at the same frequency as the received signal, the signal transmitted by the terminal device will interfere with the same frequency signal received by the terminal device. This phenomenon may be called self-interference, and the occurrence of self-interference will cause a decrease in commu...
