Abstract

A method can include selecting a channel from a network operating according to a first protocol (e.g., an IEEE 802.11ax channel). Designating at least one portion of the channel as a shared resource unit (RU) and another portion as a dedicated RU. When an associated device is communicating according to a different protocol (e.g., a Bluetooth standard), allocating frequencies of the shared RU for use by the associated device and allocating the dedicated RUs for use by the network operating according to the first protocol.

Claims (51)

1. A method, comprising:

selecting at least one resource unit (RU) from a channel in an IEEE 802.11ax compatible network based on quality indications for frequencies of the at least one RU, the channel overlapping a Bluetooth (BT) transmission spectrum;

designating the at least one RU as a shared RU and at least one other RU of the same channel as a dedicated RU; and

when an associated BT device is communicating, allocating frequencies of the shared RU for use by the associated BT device, excluding the frequencies of the shared RU for use in the IEEE 802.11ax compatible network, while concurrently allocating the dedicated RU for use by the IEEE 802.11ax compatible network; wherein

the dedicated RU and the shared RU are RUs as specified by an IEEE 802.11 wireless standard and different portions of the channel, and the channel is a portion of a larger IEEE 802.11 wireless band.

2. The method of claim 1 , further including:

generating the quality indications from a source selected from the group of: the associated BT device and an IEEE 802.11ax compatible device of the IEEE 802.11ax compatible network.

3. The method of claim 1 , wherein:

the selecting of the at least one RU is executed by an integrated circuit device that includes IEEE 802.11ax compatible circuits and the associated BT device.

4. The method of claim 1 , further including:

when the associated BT device is not communicating, allocating the shared RU for use by the IEEE 802.11ax compatible network.

5. The method of claim 1 , further including:

excluding frequencies of the dedicated RU from the transmission spectrum available to the associated BT device.

6. The method of claim 1 , further including:

storing in memory circuits data for IEEE 802.11ax channel RUs that overlap the BT transmission spectrum.

7. A device, comprising:

control circuits configured to

designate at least one resource unit (RU) of an IEEE 802.11ax channel as a shared RU based on quality indications for frequencies of the shared RU and designate at least one other RU of the same IEEE 802.11ax channel as a dedicated RU, the channel overlapping a Bluetooth (BT) transmission spectrum, and

generate a BT active indication in response to BT circuits being active;

first communication circuits configured to

transmit and receive data according to the IEEE.802.11ax standard, and

exclude the frequencies of the shared RU from IEEE.802.11ax communications in response to the BT active indication while concurrently including the dedicated RU in the IEEE.802.11ax communications; and

BT circuits configured to, when active, transmit and receive data according to at least one BT standard protocol over allocated frequencies that include the shared RU; wherein

the shared RU and the dedicated RU are RUs as specified by an IEEE 802.11 wireless standard and different portions of the same IEEE 802.11ax channel, and the channel is a portion of a larger IEEE 802.11 wireless band.

8. The device of claim 7 , wherein:

the control circuits, the first communication circuits, and the BT circuits are formed in a same integrated circuit package.

9. The device of claim 7 , wherein:

the control circuits, the first communication circuits and the BT circuits are formed in a same integrated circuit substrate.

10. The device of claim 7 , further including:

memory circuits configured to store information identifying IEEE 802.11ax channel RUs that overlap the BT transmission spectrum.

11. The device of claim 7 , wherein:

the first communication circuits further include evaluation circuits for generating quality data for transmissions on a plurality of RUs that overlap the BT transmission spectrum; and

the control circuits are configured to designate the shared RU from the plurality of RUs based on at least the quality data.

12. The device of claim 7 , wherein:

the BT circuits include BT evaluation circuits for generating BT quality data for BT channels; and

the control circuits are configured to designate the shared RU from the plurality of RUs based on at least the BT quality data.

13. The device of claim 7 , wherein:

the BT quality data comprises a bit error rate for the BT channels.

14. A system, comprising:

first protocol circuits configured to communicate according to at least a first communication protocol over allocated frequencies that include a share resource unit (RU), the first communication protocol being different than an IEEE 802.11 standard;

communication circuits configured to

designate at least one RU of an IEEE 802.11ax channel as the shared RU based on quality indications for frequencies of the shared RU and designate at least one other RU of the IEEE 802.11ax channel as a dedicated RU, the channel overlapping a transmission spectrum of the first communication protocol, and

selectively exclude the frequencies of the shared RU from IEEE 802.11ax communications according to activities of the first protocol while concurrently including the dedicated RU in IEEE 802.11ax communications; and

at least one antenna coupled to the first protocol circuits and the communication circuits; wherein

the shared RU and the dedicated RU are RUs as specified by an IEEE 802.11 wireless standard and different portions of the same IEEE 802.11ax channel, and the channel is a portion of a larger IEEE 802.11 wireless band, and the first protocol circuits comprise communication circuits compatible with at least one Bluetooth standard.

15. The system of claim 14 , wherein:

the first protocol circuits are configured to include frequencies of the shared RU as frequencies available for the first communication protocol.

16. The system of claim 14 , wherein:

the first protocol circuits are configured to exclude frequencies of the dedicated RU as frequencies available for the first communication protocol.

17. The system of claim 14 , wherein:

the first protocol circuits, communication circuits, and the at least one antenna are collocated on a same device.
