Distributed collaborative signaling in full duplex wireless transceivers
First Claim
Patent Images
1. A method comprising:
- in a full-duplex transceiver having one or more antennas, asynchronously transmitting a transmit message using a high-throughput channel multiplexed with a low-throughput channel, while simultaneously asynchronously receiving a receive message from a second full duplex transceiver;
in the full-duplex transceiver, the asynchronously receiving the receive message from the second full duplex transceiver is over a second high-throughput channel multiplexed with a second low-throughput channel; and
synchronizing the low-throughput channel with the high-throughput channel to reduce self-interference at the full-duplex transceiver.

Abstract
Two-way (full-duplex) wireless links in facilitating network management and improve network performance. Once aspect includes methods for network management using a high-throughput channel and a low-throughput channel. Other aspects include methods to facilitate practical realization and improve performance of some of the network information theoretic configurations, such as Space-Division Multiple Access (SDMA) in uplink and downlink, Interference Channel, and other forms of distributed collaborative signaling schemes. Another aspect includes methods to support cognitive wireless networks.

13. An apparatus comprising:
-
a full duplex transceiver having a transmitter and one or more antennas, configured to transmit a transmit message; the full duplex transceiver having a receiver configured to simultaneously receive a receive message from a second full duplex transceiver; the full duplex transceiver configured to asynchronously transmit the transmit message using a high-throughput channel multiplexed with a low-throughput channel, while simultaneously asynchronously receiving the receive message from the second full duplex transceiver; and a correlating receiver configured to calculate a correlation of the receive message to determine a periodicity of the receive message, and responsively reduce self-interference of the receive message. - View Dependent Claims (14, 15, 16, 17, 18, 19)
