Device, Network, and Method for Communications with Carrier Sensing and Coexistence

摘要

A network and method for wireless communications are provided. A first network element in the network may transmit a first reservation signal to reserve a channel. The first reservation signal may at least partially overlap a second reservation signal transmitted by a second network element for channel reservation. The first network element and the second network element share the same channel. The first network element may also perform interference cancellation to cancel the second reservation signal transmitted by the second network element for carrier sensing.

1. A method for wireless communications, comprising:
sensing, by a second network element, a first reservation signal transmitted by a first network element in a sensing region of a frame communicated over a carrier, wherein the first network element and the second network element share the carrier; performing, by the second network element, interference cancellation on sensed signals of the second network element to remove the first reservation signal from the sensed signals, thereby generating a residual sensed signal; and transmitting, by the second network element, a second reservation signal in the sensing region of the frame when a power level of the residual sensed signal is less than a threshold.
