Methods and arrangements to coordinate communications in a wireless network
First Claim
1. A method to wake receive circuitry of a station, the method comprising:
- receiving, by a first communications device, a communication from the station, the communication to indicate entry into an idle state by the receive circuitry of the station, the entry into the idle state to facilitate reception of a wake frame by the station to wake the receive circuitry for reception of a data packet by the station;
transmitting an acknowledgement in response to receipt of the communication;
determining, by the first communications device, to transmit the data packet to the station after an unknown time interval;
transmitting, by the first communications device, the wake frame after determining to transmit the data packet, to wake the receive circuitry of the station from the idle state to an active state, to facilitate receipt of the data packet by the station; and
transmitting, by the first communications device, the data packet to the station after the unknown time interval.

Abstract
Logic may comprise hardware and/or code to coordinate communications of wireless communications devices to reduce power consumption by stations. Logic may coordinate communications in an access point. Logic may generate and transmit a wake frame from the access point to the station to wake the receive circuitry of the station. Logic of the station may wake the receive circuitry from an idle mode, which may be a less linear and less sensitive mode, to a receiver (RX) active state, which is a high linear and high sensitivity mode. Once the receiver circuitry enters the RX active state, the station is ready to receive a transmission. Logic may implement the wake frame as a medium access control frame or as a null data packet, physical layer frame.
