Abstract
Devices, softwares and methods reschedule multi-party sessions upon premature termination of a wireless communication session. Upon sensing a premature termination, an access point transmits a rescheduling frame. All sessions are advanced in time, which saves time in the end, without leaving quiet times. In addition, the invention avoids a hidden node problem.
Claims30
A device comprising:
- a memory;
- and
- a processor coupled with the memory, wherein the processor is adapted to
- generate a schedule for exchanging data with only a first peripheral device during a first time window, and for exchanging data with only a second peripheral device after the first time window;
- transmit at least one multi-poll scheduling frame that encodes the schedule;
- exchange data with the first peripheral device after the scheduled first time window starts;
- complete exchanging data with the first peripheral device before the first time window ends;
- then transmit a rescheduling frame;
- and
- then exchange data with the second peripheral device before the first time window ends.

A device comprising:
- a memory;
- and
- a processor coupled with the memory, wherein the processor is adapted to receive at least one multi-poll scheduling frame;
- decode from the received multi-poll scheduling frame a schedule for a first time window and for a subsequent second time window during which to exchange data;
- during the first time window, receive a rescheduling frame;
- reschedule the second time window in response to the rescheduling frame;
- and
- then exchange data during the rescheduled second time window before the first time window ends.

An article comprising:
- a storage medium, said storage medium having stored thereon instructions, that, when executed by at least one device, result in:
- generating a schedule for exchanging data with only a first peripheral device during a first time window, and for exchanging data with only a second peripheral device after the first time window;
- transmitting at least one multi-poll scheduling frame that encodes the schedule;
- exchanging data with the first peripheral device after the scheduled first time window starts;
- completing exchanging data with the first peripheral device before the first time window ends;
- then transmitting a rescheduling frame;
- and
- then exchanging data with the second peripheral device before the first time window ends.
