Methods and arrangements to coordinate communications in a wireless network

摘要

Logic to coordinate communications of wireless communications devices to attenuate collisions, such as through coordination of communications by implementing slot logic in an access point. The slot logic may determine a time slot schedule for beacon intervals and may further transmit a synch frame at the time slot boundaries. If the channel is busy, the slot logic may not send the synch frame. The slot logic may also comprise distribution logic to determine a probability of collisions and to instruct one or more of the devices to spread out their channel accesses across beacons intervals to reduce the chance of collisions. A station associated with the access point may comprise synch logic to wake up at a slot boundary and wait for a synch frame or any other packets to synch to the medium.

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