Methods and arrangements to coordinate communications in a wireless network

A first wireless communication device comprising:

• at least one processor, memory, a medium access control (MAC) layer logic and
• a physical (PHY) layer logic, the first wireless communication device to
• determine a time slot schedule between beacon frame transmissions by determination of the time slot schedule with time slots, wherein each time slot may be a time duration of at least a duration for transmission of a physical layer convergence procedure protocol data unit plus a short interframe space;
• transmit a beacon in a communication channel, the beacon having the time slot schedule for multiple time slots to be included in a beacon interval;
• transmit a first synch frame at a slot boundary of a first time slot if the communication channel is not busy at the slot boundary;
• not transmit the first synch frame at the slot boundary of the first time slot if the communication channel is busy at the slot boundary.

A program product to coordinate transmissions of devices on a wireless network, the program product comprising:

• a storage medium comprising instructions to be executed by a processor-based device, wherein the instructions, when executed by the processor-based device, perform operations, the operations comprising:
• determining the time slot schedule between beacon frame transmissions by determining the time slot schedule with time slots, wherein each time slot may be a time duration of at least a duration for transmission of a physical layer convergence procedure protocol data unit plus a short interframe space;
• transmitting, by a first communications device, a beacon in a communication channel, the beacon having a time slot schedule for multiple time slots to be included in a beacon interval;
• transmitting, by the first communications device, a first synch frame at a slot boundary of a first time slot if the communication channel is not busy at the slot boundary;
• and
• not transmitting, by the first communications device, the first synch frame at the slot boundary of the first time slot if the communication channel is busy at the slot boundary.

A method to coordinate transmissions of devices on a wireless network, the method comprising:

• receiving, by a first communications device from a second communications device, a first beacon frame during a beacon interval indicating a time slot schedule during the beacon interval, wherein each time slot of the time slot schedule may be a time duration of at least a duration for transmission of a physical layer convergence procedure protocol data unit plus a short interframe space;
• waking, by the first communications device, from a doze state to an awake state to receive a first synch frame at a boundary of a time slot;
• and
• receiving, from the second communications device, the first synch frame to synch with a channel during the beacon interval;
• and
• transmitting a communication to the second communications device after synching with the channel.

An apparatus to coordinate transmissions of devices on a wireless network, the apparatus comprising:

• at least one processor;
• memory;
• a medium access control logic to receive a first beacon frame during a beacon interval indicating a time slot schedule during the beacon interval;

• and
• a physical layer logic coupled with the medium access control logic to receive, from the second communications device, the first synch frame to synch with a channel during the beacon interval, wherein each time slot of the time slot schedule may be a time duration of at least a duration for transmission of a physical layer convergence procedure protocol data unit plus a short interframe space;
• inform the medium access control logic of receipt of the first synch frame;
• and transmit a communication to the second communications device after synching with the channel.
