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-STAB) 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 type of device to reduce power consumption by a second type of device caused by contentions between the first type of device and the second type of device, comprising:

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

at least one processor configured to access the at least one memory, 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 type of 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 type of device;

determine a periodicity of the time duration;

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

cause to send the beacon frame.

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

3. The wireless access point device of claim 1, wherein the information element is configured to restrict the first type of 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 a station of the second type of device during the time duration, the communication indicative of an adoption by the station of the time duration.

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

determine an absence of a communication from the second type of 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 a station of the second type of 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 type of device to communicate with a wireless access point device, and during which time a second type of 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 type of device;

determining a periodicity of the time duration;

generating a beacon frame including the time duration, an indication of the periodicity, and an indication of the first type of device for which the time duration is allocated for communications with the wireless access point device, wherein the beacon frame includes an information element comprising a duration field for the time duration of the time slot, a periodicity field for the periodicity of the time slot, and a device field for the type of device; and

causing to send the beacon frame.

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

11. The non-transitory computer-readable medium of claim 9, wherein the information element is configured to prevent the second type of device from communicating with the wireless access point device when the first type of 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 a station of the second type of device, the communication indicative of an adoption by the station of the time duration.

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 type of device during the time duration 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 a station of the first type of device.

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

determining a time duration indicative of time allocated for the second type of device to communicate with a wireless access point device, and during which time the first type of 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 type of device;

determining a periodicity of the time duration;

generating a beacon frame including the time duration, an indication of the periodicity, and an indication of the second type of device for which the time duration is allocated for communications with the access point device, wherein the beacon frame includes an information element comprising a duration field for the time duration of the time slot, a periodicity field for the periodicity of the time slot, and a device field for the type of device; and
