Abstract

One aspect of the disclosure provides a method performed by a transmitting device, for transmitting wirelessly to a receiving device in a wireless network. The method comprises: obtaining information which is indicative of a level of wireless activity caused by interfering transmissions by one or more interfering devices, experienced by one or more receiving devices on one or more first channels configured for transmissions by the one or more receiving devices; and determining whether to transmit to a receiving device of the one or more receiving devices using one or more second channels based on the information indicative of the level of wireless activity experienced by the one or more receiving devices on the one or more first channels.

First claim

The invention claimed is:

1. A method, performed by a transmitting device, for transmitting wirelessly to a receiving device in a wireless network, the method comprising the transmitting device:
obtaining information which is indicative of a level of wireless activity caused by interfering transmissions by one or more interfering devices, experienced by one or more receiving devices on one or more first channels configured for transmissions by the one or more receiving devices;
determining, based on the information indicative of the level of wireless activity experienced by the one or more receiving devices on the one or more first channels, whether the one or more receiving devices will be prevented from transmitting an acknowledgement or response message in response to a transmission by the transmitting device; and
determining whether to transmit to a receiving device of the one or more receiving devices using one or more second channels based on the determination whether the receiving device will be prevented from transmitting the acknowledgement or response message.

2. The method of claim 1 :
further comprising performing carrier-sensing to detect a level of wireless activity on one or more second channels configured for transmissions by the transmitting device;
wherein the transmitting device additionally determines whether to transmit to a receiving device of the one or more receiving devices based on an outcome of the carrier-sensing.

3. The method of claim 2 :
wherein the performing carrier-sensing comprises detecting further interfering transmissions by one or more further interfering devices on the one or more second channels;
wherein the method further comprises obtaining information which is indicative of a geographical location of the one or more further interfering devices;
wherein the determination whether to transmit to a receiving device is based on the geographical location of the one or more further interfering devices.

4. The method of claim 1 , wherein determining whether the one or more receiving devices will be prevented from transmitting an acknowledgement or response comprises determining, based on the information indicative of the level of wireless activity experienced by the one or more receiving devices on the one or more first channels, whether the one or more receiving devices will be prevented from transmitting an acknowledgement or response message in response to a transmission by the transmitting device owing to a carrier-sense failure at the one or more receiving devices.

5. The method of claim 1 :
wherein the one or more receiving devices comprise a plurality of receiving devices; and
wherein the determining whether to transmit to a receiving device comprises determining which of the plurality of receiving devices to transmit to.

6. The method of claim 1 , wherein the obtaining information comprises detecting the interfering transmissions, and obtaining the information from the one or more detected interfering transmissions.

7. The method of claim 1 , wherein the obtaining information comprises receiving the information in one or more wireless messages transmitted by the one or more receiving devices.

8. The method of claim 1 , wherein the information comprises an indication of the geographical location of the one or more interfering devices.

9. The method of claim 8 , wherein the indication of the geographical location of the one or more interfering devices comprises an angle of arrival at the transmitting device or the receiving device of the interfering transmission by the one or more interfering devices.

10. The method of claim 8 , wherein the indication of the geographical location of the one or more interfering devices comprises an identifier associated with a basic service set to which the interfering device belongs.

11. The method of claim 1 , wherein the information comprises an indication of the geographical location of one or more interfering receiving devices, to which the one or more interfering transmissions are directed.

12. The method of claim 11 , wherein the indication of the geographical location comprises an identity of the one or more interfering receiving devices obtained by decoding the one or more interfering transmissions.

13. A method, performed by a receiving device, for scheduling transmissions by a transmitting device in a wireless network, the method comprising the receiving device:
obtaining information which is indicative of a level of wireless activity caused by interfering transmissions by one or more interfering devices, wherein the interfering transmissions are experienced by one or more transmitting devices comprising the transmitting device, on one or more first channels configured for transmissions by the one or more transmitting devices;
determining, based on the information indicative of the level of wireless activity experienced by the one or more transmitting devices on the one or more first channels, whether the transmitting device will be prevented from transmitting one or more uplink messages to the receiving device; and
based on the determination whether the transmitting device will be prevented from transmitting the one or more uplink messages, determining whether to transmit a polling or scheduling message to the transmitting device, wherein the polling or scheduling message schedules resources in which to transmit one or more uplink messages from the transmitting device.

14. The method of claim 13 :
further comprising performing carrier-sensing to detect a level of wireless activity on one or more second channels configured for transmissions by the receiving device;
wherein determining whether to transmit a polling or scheduling message to a transmitting device of the one or more transmitting devices is further based on an outcome of the carrier-sensing.

15. The method of claim 13 :
wherein the one or more transmitting devices comprise a plurality of transmitting devices;
wherein the determining whether to transmit a polling or scheduling message to a transmitting device comprises determining which of the plurality of transmitting devices to transmit a polling or scheduling message to.

16. The method of claim 13 , wherein the obtaining information comprises detecting the interfering transmissions, and obtaining the information from the one or more detected interfering transmissions.

17. The method of claim 13 , wherein the obtaining information comprises receiving the information in one or more wireless messages transmitted by the one or more transmitting devices.

18. The method of claim 13 , wherein the information comprises an indication of the geographical location of the one or more interfering devices.

19. The method of claim 13 , wherein the information comprises an indication of the geographical location of one or more interfering receiving devices, to which the one or more interfering transmissions are directed.

20. The method of claim 13 wherein the determining whether the one or more transmitting devices will be prevented from transmitting comprises determining the one or more transmitting devices will be prevented from transmitting one or more uplink messages to the receiving device owing to a carrier-sense failure.

21. A transmitting device, for transmitting wirelessly to a receiving device in a wireless network, the transmitting device comprising:
processing circuitry;
memory containing instructions executable by the processing circuitry whereby the transmitting device is operative to
