Abstract

In one embodiment, a method includes obtaining a first transmission opportunity (TXOP) on a first shared channel by winning a first channel contention of the first shared channel, and obtaining a second transmission opportunity (TXOP) on the first shared channel by winning a second channel contention of the first shared channel. Transmitting a first transmission according to the first TXOP, the first transmission being part of a transmission sequence; receiving the first transmission response, the response being received through a second shared channel, the first shared channel and the second shared channel operating on different radio frequency carriers; obtaining a second TXOP by winning a second channel contention; and transmitting a second transmission according to the second TXOP, wherein the second transmission is part of the transmission sequence.

Description

technical field

[0001] The present invention relates generally to systems and methods for digital communications, and in particular embodiments to methods and apparatus for aggregating multiple wireless communication channels for flexible full-duplex communications. Background technique

[0002] A duplex communication system is a point-to-point system consisting of two or more devices capable of communicating with each other in two directions. There are two types of duplex communication systems: full duplex and half duplex. In a full-duplex system, two devices are able to communicate with each other simultaneously. In a half-duplex system, two devices are able to communicate with each other, but not at the same time, ie, communication is one direction at a time.

[0003] Time-division duplexing (TDD) simulates full-duplex communication over a half-duplex channel by separating the outgoing and return signals in the time domain. When the uplink and downlink services are asy...
