Methods and arrangements to coordinate communications in a wireless network
First Claim
1. An apparatus to wake receive circuitry of a station, the apparatus comprising:
- memory; and
logic, at least a portion of which is in hardware, the logic to encode an acknowledgement to transmit in response to decoding a communication received from the station;
to determine, after an unknown time interval, to encode a data packet to transmit to the station;
to encode a wake frame to transmit 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
to encode the data packet to transmit 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.

8. A method to wake receive circuitry of a station, the method comprising:
-
transmitting, by a first communications device, an acknowledgement in response to receipt of a communication from the station; after an unknown time interval, determining, by the first communications device, to transmit the data packet to the station; transmitting, by the first communications device, a 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. - View Dependent Claims (9, 10, 11, 12, 13, 14)

15. A program product to wake receive circuitry of a station, the program product comprising:
-
a computer-readable 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; transmitting an acknowledgement in response to receipt of a communication; determining, after an unknown time interval by a first communications device, to transmit a data packet to the station; transmitting a wake frame after determining to transmit the data packet, to wake 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 the data packet to the station after the unknown time interval. - View Dependent Claims (16, 17, 18, 19, 20, 21)

22. A method to wake receive circuitry of a station, the method comprising:
-
receiving an acknowledgement responsive to a communication; entering an idle state to reduce power consumption by the receive circuitry; waiting, in the idle state, an unknown time interval to receive the data packet; receiving, by the station, the wake frame, while the receive circuitry of the station remains in the idle state; waking, by the station, the receive circuitry of the station from the idle state to a receive active state to receive the data packet in response to the wake frame; and receiving the data packet after the unknown time interval. - View Dependent Claims (23, 24)
