Method and apparatus for handling full-duplex interference
First Claim
1. A method for handling full-duplex interference, the method comprising:
- obtaining an interference degree that is caused when a site device performs full-duplex transmission with at least two User Equipment (UEs), wherein obtaining an interference degree comprises,obtaining a degree of mutual interference between uplink and downlink signals of the at least two UEs during full-duplex transmission, andobtaining a degree of self-interference of a transmit signal on a received signal of the site device during full-duplex transmission, wherein obtaining a degree of self-interference comprises,obtaining power information of self-interference of the transmit signal on the received signal, andobtaining, according to the power information of self-interference and power information of the received signal, a degree of difference between self-interference power and received signal power, and determining, according to the degree of difference, a degree of self-interference; and
determining, according to the interference degree, UEs allowed to transmit uplink and downlink signals with the site device on a same time and frequency resource among the at least two UEs;
wherein one or more UEs that are determined to transmit uplink signals and one or more UEs that are determined to transmit downlink signals on the same time and frequency resource are classified as having a low interference degree.

Abstract
The present invention provides a method and an apparatus for handling full-duplex interference. One method includes: obtaining an interference degree that is caused when a site device performs full-duplex transmission with at least two UEs; and determining, according to the interference degree, a UE allowed to transmit uplink and downlink signals on the same time and frequency resource among the at least two UEs. In embodiments of the present invention, a UE allowed to transmit uplink and downlink signals on the same time and frequency resource may be classified according to an interference degree that is caused when a site device performs full-duplex transmission with at least two UEs, thereby preventing the interference problem in the scenario of point-to-multipoint full-duplex communication as much as possible.
