Abstract

Logic may coordinate communications of different types of wireless communications devices such as high power and low power wireless communications devices. Logic may coordinate communications by assigning time slots to a low power station (LP-STA) in a management frame such as a beacon transmitted by an access point (AP) associated with the LP-STA. Logic of the high power stations (HP-STAs) may receive the beacon and shepard logic of the HP-STA may defer transmissions by the HP-STA throughout the duration(s) indicated in the beacon from the AP. Logic of the LP-STA may comprise carrier sense multiple access with collision avoidance logic to determine when to transmit a communication. Shepard logic of an HP-STA may detect the communication from the LP-STA and defer transmission of communication during a time duration for the communication by the LP-STA.

Claims

1. A wireless access point device that controls access by a first device to reduce power consumption by a second device caused by contentions between the first device and the second device, comprising:

at least one storage that stores computer-executable instructions; and

at least one processor configured to access the at least one storage, wherein the at least one processor is configured to execute the computer-executable instructions to;

determine a time duration indicative of time reserved for the second device to communicate with the wireless access point device, wherein the time duration is further indicative of a duration of a time slot allocated to the second device;

determine a periodicity of the time duration;

generate a beacon frame including an indication of the periodicity, and an indication of the second device for which the time duration is reserved for communication with the wireless access point device, wherein the beacon frame includes information indicative of the time duration of the time slot, the periodicity of the time slot, and a device identifier; and

cause to send the beacon frame.

2. The wireless access point device of claim 1, wherein the second device includes a sensor.

3. The wireless access point device of claim 1, wherein the beacon frame is associated with restricting the first device from communicating with the wireless access point device during the time duration.

4. The wireless access point device of claim 1, wherein the at least one processor is further configured to execute the computer-executable instructions to identify a communication received from the second device during the time duration, the communication indicative of an adoption of the time duration by the second device.

5. The wireless access point device of claim 1, wherein the at least one processor is further configured to execute the computer-executable instructions to:

determine an absence of a communication from the second device during the time duration indicated in the beacon frame,

determine a second time duration that is shorter than the time duration,

generate a second beacon frame including the second time duration, and

cause to send the second beacon frame.

6. The wireless access point device of claim 1, wherein the at least one processor is further configured to execute the computer-executable instructions to detect, prior to the determination of the time duration, a transmission by the second device.

7. The wireless access point device of claim 1, further comprising a transceiver configured to send and receive wireless signals.

8. The wireless access point device of claim 7, further comprising one or more antennas coupled to the transceiver.

9. A non-transitory computer-readable medium storing computer-executable instructions that, when executed by at least one processor, configure the at least one processor to perform operations comprising:

determining a time duration indicative of time allocated for a first device to communicate with a wireless access point device, and during which time a second device is restricted from communicating with the wireless access point device, wherein the time duration is further indicative of a duration of a time slot allocated to the first device;

determining a periodicity of the time duration;

generating a beacon frame including an indication of the periodicity, and an indication of the second device for which the time duration is reserved for communication with the wireless access point device, wherein the beacon frame includes information indicative of the time duration of the time slot, the periodicity of the time slot, and a device identifier; and

causing to send the beacon frame.

10. The non-transitory computer-readable medium of claim 9, wherein the first device includes a sensor.

11. The non-transitory computer-readable medium of claim 9, wherein the beacon frame is associated with preventing the second device from communicating with the wireless access point device when the first device is communicating with the wireless access point device.

12. The non-transitory computer-readable medium of claim 9, the processor further configured to perform operations comprising identifying a communication received during the time duration from second device, the communication indicative of an adoption of the time duration by the second device.

13. The non-transitory computer-readable medium of claim 9, the processor further configured to perform operations comprising:

determining an absence of a communication from the first device during the time duration indicated in the beacon frame,

determining a second time duration that is shorter than the time duration,

generating a second beacon frame including the second time duration, and

causing to send the second beacon frame.

14. The non-transitory computer-readable medium of claim 9, the processor further configured to perform operations comprising detecting, prior to the determination of the time duration, a transmission by the first device.

15. A method for limiting access to a wireless access point by a first device to reduce power consumption by a second device caused by contentions between the first device and the second device, comprising:

determining a time duration indicative of time allocated for the second device to communicate with a wireless access point device, and during which time the first device is restricted from communicating with the wireless access point device, wherein the time duration is indicative of a duration of a time slot allocated to the first device;

determining a periodicity of the time duration;

generating a beacon frame including an indication of the periodicity, and an indication of the second device for which the time duration is reserved for communication with the wireless access point device, wherein the beacon frame includes information indicative of the time duration of the time slot, the periodicity of the time slot, and a device identifier; and

causing to send the beacon frame.

16. The method of claim 15, wherein the first device includes a sensor.

17. The method of claim 15, wherein the beacon frame is associated with preventing the first device from communicating with the wireless access point device when the second device is communicating with the wireless access point device.

18. The method of claim 15, further comprising identifying a communication received from the second device during the time duration, the communication indicative of an adoption of the time duration by the second device.

19. The method of claim 15, further comprising:

determining an absence of a communication from the second device during the time duration indicated in the beacon frame,

determining a second time duration that is shorter than the time duration,

generating a second beacon frame including the second time duration, and

causing to send the second beacon frame.

20. The method of claim 15, further comprising detecting, prior to the determination of the time duration, a transmission by the second device.
