Abstract
Devices, softwares and methods advance the scheduling of a next contention session upon premature termination of a contention free session. A Hybrid Coordinator detects when the exchange of wireless transmissions finishes before the contention free window is scheduled to end. Upon such detection, the Hybrid Coordinator transmits a notification to advance the scheduling of the next contention session. Upon sensing the notification, contention resumes by the participating peripherals.
Claims36
A device comprising:
- a physical communication component;
- and
- a processor coupled with the physical communication component, in which the processor is adapted to
- receive contending requests for respective wireless transmissions through a medium;
- schedule an ending time of a time window during which subsequent contending requests are impermissible;
- communicate the scheduled ending time;
- monitor the medium;
- determine that one of the wireless transmissions through the monitored medium ended before the scheduled ending time;
- and
- communicate that subsequent contending requests are permissible even if made before the scheduled ending time.
7 more elements
A device comprising:
- a physical communication component;
- and
- a processor coupled with the physical communication component, in which the processor is adapted to
- receive data about a contention-free time window regarding a medium;
- decode from the data a scheduled ending time of the time window;
- then receive notification that contention will be permitted before the scheduled ending time;
- and
- contend for the medium before the scheduled ending time pursuant to the notification.
5 more elements
A device comprising:
- means for receiving contending requests for respective wireless transmissions through a medium;
- means for scheduling an ending time of a time window during which subsequent contending requests are impermissible;
- means for communicating the scheduled ending time;
- means for monitoring the medium;
- means for determining that one of the wireless transmissions through the monitored medium ended before the scheduled ending time;

4 more elements
A device comprising:
- means for receiving data about a contention-free time window regarding a medium;
- means for decoding from the data a scheduled ending time of the time window;
- means for then receiving notification that contention will be permitted before the scheduled ending time;
- and
- means for contending for the medium before the scheduled ending time pursuant to the notification.
2 more elements
An article comprising:
- a storage medium, the storage medium having instructions stored thereon, in which when the instructions are executed by at least one device, they result in:
- receiving contending requests for respective wireless transmissions through a medium;
- scheduling an ending time of a time window during which subsequent contending requests are impermissible;
- communicating the scheduled ending time;
- monitoring the medium;
- determining that one of the wireless transmissions through the monitored medium ended before the scheduled ending time;
- and
- communicating that subsequent contending requests are permissible even if made before the scheduled ending time.
