Methods and Arrangements for Adaptive Delay Control
First Claim
1. A method to coordinate transmissions of devices on a wireless network, the method comprising:
- generating, by a first communications device, a frame indicating a delay, the frame to instruct other communication devices in the wireless network to defer for the delay, wherein deference by each of the other communications devices is triggered in each of the other communications devices by a switch from a doze state to an awake state absent detection of a frame sequence with a network allocation vector that results in the network allocation vector being set before an expiration of the delay; and
transmitting, by the first communications device, the frame.

Abstract
Logic may comprise hardware and/or code to coordinate communications of wireless communications devices. Logic coordinate communications in an access point by implementing adaptive delays. Logic may determine a delay for stations awaking from a doze state during which the station should perform clear channel assessment prior to transmitting packets on a channel. Logic may collect information about devices and/or communications within a basic service set (BSS) such as the statistics of the received packets length in time, the type of stations in the network, and/or other information available. Based upon the information collected, the logic may determine a delay and transmit the delay to devices in the BSS. Logic may receive and update the delay in memory and then implement the delay after switching to an awake state from a doze state.
