Methods, Systems, And Apparatus To Reduce Inter Station Interference In A Full Duplex Communication Protocol

Abstract: Methods and apparatus to reduce inter-station interference in a full-duplex communication protocol are disclosed. An example apparatus includes a station selector to select a first station and second station, the first station being capable of performing a successive interference cancellation; a full-duplex configuration determiner to determine an uplink transmission configuration and a downlink transmission configuration based on a decodability requirement; and a component interface to transmit a trigger frame to the first and second stations, the trigger frame corresponding to a full-duplex communication based on the uplink transmission configuration and the downlink transmission configuration.

Specification

What Is Claimed Is: 1. An apparatus to facilitate a reduction of inter-station interference in a full-duplex communication protocol, the apparatus comprising:
a station selector to select a first station and second station, the first station being capable 5 of performing a successive interference cancellation;
a full-duplex configuration determiner to determine an uplink transmission configuration and a downlink transmission configuration based on a decodability requirement; and
a component interface to transmit a trigger frame to the first and second stations, the trigger frame corresponding to a full-duplex communication based on the uplink transmission 10 configuration and the downlink transmission configuration.
2. The apparatus of claim 1, further including a packet processor to determine that
the first station is capable of performing the successive interference cancellation based on an
advertisement from the first station.
3. The apparatus of claim 1, further including a packet processor to determine a
15 signal strength requirement of the first station based on a data packet from the first station, the
full-duplex configuration determiner to determine the uplink transmission configuration and the downlink transmission configuration further based on the signal strength requirement.
4. The apparatus of claims 1-3, wherein the full-duplex communication corresponds
to transmitting a downlink signal to the first station while receiving an uplink signal from the
20 second station.
5. The apparatus of claim 4, wherein the decodability requirement corresponds to a
ratio of an interference signal strength to a downlink signal strength meeting a minimum signal-
to-noise ratio requirement for decoding an interference signal on the downlink signal.
6. The apparatus of claim 5, wherein the interference signal strength is a signal
25 strength of the uplink signal seen at the first station.
7. The apparatus of claims 1-3, further including a full-duplex communication
facilitator to facilitate the full-duplex communication between the first and second stations based
on the uplink transmission configuration and the downlink transmission configuration.
8. The apparatus of claim 7, wherein the component interface receives a processing
30 time requirement from the first station, the full-duplex communication facilitator to delay
transmission of a downlink signal based on the processing time requirement.

9. A method to facilitate a reduction of inter-station interference in a full-duplex
communication protocol, the method comprising:
selecting, by executing instructions using a processor of an access point, a first station and second station, the first station being capable of performing a successive interference cancellation;
determining, by executing instructions using a processor of the access point, an uplink transmission configuration and a downlink transmission configuration based on a decodability requirement; and
transmitting, by executing instructions using a processor of the access point, a trigger frame to the first and second stations, the trigger frame corresponding to a full-duplex communication based on the uplink transmission configuration and the downlink transmission configuration.
10. The method of claim 9, further including determining that the first station is capable of performing the successive interference cancellation based on an advertisement from the first station.
11. The method of claim 9, further including determining a signal strength requirement of the first station based on a data packet from the first station, the determining of the uplink transmission configuration and the downlink transmission configuration being further based on the signal strength requirement.
12. The method of claims 9-11, wherein the full-duplex communication corresponds to transmitting a downlink signal to the first station while receiving an uplink signal from the second station.
13. The method of claim 12, wherein the decodability requirement corresponds to a ratio of an interference signal strength to a downlink signal strength meeting a minimum signal-to-noise ratio requirement for decoding an interference signal on the downlink signal.
14. The method of claim 13, wherein the interference signal strength is a signal strength of the uplink signal seen at the first station.
15. The method of claims 9-11, further including facilitating the full-duplex communication between the first and second stations based on the uplink transmission configuration and the downlink transmission configuration.

16. The method of claim 15, further including receiving a processing time requirement from the first station, the full-duplex communication facilitator to delay transmission of a downlink signal based on the processing time requirement.
17. A tangible computer readable medium comprising instruction which, when executed, cause a machine to at least:
select a first station and second station, the first station being capable of performing a successive interference cancellation;
determine an uplink transmission configuration and a downlink transmission configuration based on a decodability requirement; and
transmit a trigger frame to the first and second stations, the trigger frame corresponding to a full-duplex communication based on the uplink transmission configuration and the downlink transmission configuration.
18. The tangible computer readable medium of claim 17, wherein the instructions cause the machine to determine that the first station is capable of performing the successive interference cancellation based on an advertisement from the first station.
19. The tangible computer readable medium of claim 17, wherein the instructions cause the machine to determine a signal strength requirement of the first station based on a data packet from the first station, the determining of the uplink transmission configuration and the downlink transmission configuration being further based on the signal strength requirement.
20. The tangible computer readable medium of claims 17-19, wherein the full-duplex communication corresponds to transmitting a downlink signal to the first station while receiving an uplink signal from the second station.
21. The tangible computer readable medium of claim 20, wherein the decodability requirement corresponds to a ratio of an interference signal strength to a downlink signal strength meeting a minimum signal-to-noise ratio requirement for decoding an interference signal on the downlink signal.
22. The tangible computer readable medium of claim 21, wherein the interference signal strength is a signal strength of the uplink signal seen at the first station.
23. The tangible computer readable medium of claims 17-19, wherein the instructions cause the machine to facilitate the full-duplex communication between the first and second

stations based on the uplink transmission configuration and the downlink transmission configuration.
24. The tangible computer readable medium of claim 23, wherein the instructions cause the machine to receive a processing time requirement from the first station, the full-duplex communication facilitator to delay transmission of a downlink signal based on the processing time requirement.
25. An apparatus to reduce inter-station interference in a full-duplex communication protocol, the apparatus comprising memory and processing circuity, configured to:
select a first station and second station, the first station being capable of performing a successive interference cancellation;
determine an uplink transmission configuration and a downlink transmission configuration based on a decodability requirement; and
