Methods and arrangements to coordinate communications in a wireless network

An apparatus to wake receive circuitry of a station before receipt of data by the station, the apparatus comprising:

• logic to determine, upon receiving a trigger frame from the station, to transmit a data packet to the station;
• to transmit a frame comprising an indication that the data packet will be transmitted;
• to generate a wake frame comprising a duration associated with the data packet and a receiver address of the station to receive the data packet;
• and
• a physical layer in communication with the logic to transmit the wake frame at a low modulation and code rate, after an unknown time interval, to wake the station from a receive idle state to a receive active state, wherein the low modulation and code rate is a modulation and code rate that the station can receive in the receive idle state.

A program product to wake receive circuitry of a station before receipt of the data by the station, the program product comprising:

• a non-transitory 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:
• determining, upon receiving a trigger frame from the station, to transmit a data packet to the station;
• transmitting a frame comprising an indication that the data packet will be transmitted;
• generating a wake frame comprising a duration associated with the data packet and a receiver address of the station;
• transmitting the wake frame at a low modulation and code rate, after an unknown time interval, to wake the station from a receive idle state to a receive active state, wherein the low modulation and code rate is a modulation and code rate that the station can receive in the receive idle state.

A method to wake receive circuitry of a station before receipt of the data by the station, the method comprising:

• waiting, by the station, after receiving a frame comprising an indication that the data packet will be transmitted, in a receive idle state, an unknown time interval to receive a data packet;
• receiving, by the station, a wake frame indicating a receive address and a duration for the data packet to be transmitted to the receive address, while the station remains in the receive idle state;
• determining, by the station, that the receive address is associated with the station;
• waking, by the station, receive circuitry of the station from the receive idle state to a receive active state to receive the data packet in response to the wake frame;
• and receiving the data packet.
