Abstract
Embodiments relate to wireless stations that operate to configure direct communication between the wireless stations without utilizing an intermediate access point. In embodiments, a wireless station may establish a peer-to-peer communication schedule with at least one neighboring peer wireless station, announce, to the at least one neighboring peer wireless station, a schedule transition (or migration), wherein the schedule transition includes an effective time of a new schedule, and announce, to the at least one neighboring peer wireless station, the new schedule at the effective time.
Claims20
A wireless device, comprising:
- at least one antenna;
- at least one radio in communication with the at least one antenna and configured to perform communications via a Wi-Fi interface;
- and
- at least one processor in communication with the at least one radio;
- wherein the at least one processor is configured to cause the wireless device to:
- establish a peer-to-peer communication schedule with at least one neighboring peer device, wherein the communication is conducted according to a Wi-Fi peer-to-peer communication protocol;
- announce, to the at least one neighboring peer device, a schedule migration, wherein the schedule migration includes an effective time of a new schedule;
- and
- announce, to the at least one neighboring peer device, the new schedule at or before the effective time.
An apparatus, comprising:
- a memory;
- and
- at least one processor in communication with the memory;
- wherein the at least one processor is configured to:
- communicate with at least one neighboring peer device according to a negotiated schedule, wherein the communication is according to a Wi-Fi peer-to-peer communication protocol;
- transmit, to the at least one neighboring peer device, an intention to change the negotiated schedule indicating an effective time of a new schedule;
- and
- transmit, to the at least one neighboring peer device, the new schedule at or before the effective time.
A non-transitory computer readable memory medium storing program instructions executable by a processor to:
- communicate with one or more neighboring peer devices according to an availability schedule, wherein the availability schedule specifies one or more times and channels for communications with the one or more neighboring peer devices;
- broadcast to the one or more neighboring peer devices an effective time of a new schedule;
- and
- broadcast to the one or more neighboring peer devices the new schedule at or before the effective time.
