1. A wireless apparatus comprising:
- a wireless transceiver, communicatively coupled with a processor within the wireless apparatus, the wireless transceiver configured to transmit and receive communications via a wireless network;
the processor configured to receive a first schedule definition and a second schedule definition from a networking device of the wireless network;
the processor further configured to determine, from the received first schedule definition and the received second schedule definition, downlink reception times;
the processor further configured to start a timer at one of the determined downlink reception times;
the processor further configured to determine, during a duration of the timer, whether a downlink transmission including a message is being communicated from the networking device to the wireless apparatus;
the processor further configured to discontinue reception at expiration of the timer;
the processor further configured, in response to reception of the downlink transmission, to transmit an acknowledgement and to discontinue reception before the timer has expired; and
the wireless transceiver further configured to adjust an uplink transmission time for a communication to the networking device based on a determined amount of time drift.

Abstract
A wireless apparatus may receive scheduling definitions from a networking device. The wireless apparatus may determine, from the scheduling definitions, downlink transmission times and to start a timer at one of the determined downlink transmission times. The wireless apparatus may discontinue reception at expiration of the timer. The wireless apparatus may also, in response to reception of a downlink transmission, transmit an acknowledgement and to discontinue reception before the timer has expired.

8. A method of communicating within a wireless network via a wireless apparatus, the method comprising:
-
receiving, by the wireless apparatus, a first schedule definition and a second schedule definition indicating downlink reception times; starting, by the wireless apparatus, a timer at one of the indicated downlink reception times; determining, by the wireless apparatus during a duration of the timer, whether a downlink transmission including a message is being communicated from a networking device to the wireless apparatus; discontinuing, by the wireless apparatus, reception at expiration of the timer; transmitting, by the wireless apparatus in response to receiving the downlink transmission, an acknowledgement and discontinuing reception before the timer has expired; and adjusting, by the wireless apparatus, an uplink transmission time for a communication to the networking device based on a determined amount of time drift. - View Dependent Claims (9, 10, 11, 12, 13, 14, 15)

16. A wireless network device comprising:
-
a wireless transceiver, communicatively coupled with a processor, the wireless transceiver configured to transmit and receive communications via a wireless network; the wireless transceiver configured to transmit a first schedule definition and a second schedule definition indicating downlink transmission times allocated for one of a plurality of wireless apparatuses within the wireless network; the processor further configured to start a timer, for the one of the plurality of wireless apparatuses, at one of the indicated downlink transmission times; the processor further configured to determine, during a duration of the timer, whether a downlink transmission including a message will be communicated to the one of the plurality of wireless apparatuses; the processor further configured to discontinue transmission at expiration of the timer; the processor further configured to send the downlink transmission to the one of the plurality of wireless apparatuses and to discontinue transmission when an acknowledgement is received before the timer has expired; and the wireless transceiver configured to receive information from one of the plurality of wireless apparatuses at an uplink transmission time that is adjusted based on a determined amount of time drift. - View Dependent Claims (17)

18. A method performed by a wireless apparatus, the method comprising:
-
transmitting and receiving, by the wireless apparatus, communications via a wireless network; receiving, by the wireless apparatus, a first schedule definition and a second schedule from a networking device of the wireless network; determining, by the wireless apparatus from the received first schedule definition and the received second schedule definition, downlink reception times; starting, by the wireless apparatus, a timer at one of the determined downlink reception times; determining, by the wireless apparatus during a duration of the timer, whether a downlink transmission including a message is being communicated from the networking device to the wireless apparatus; discontinuing, by the wireless apparatus, reception at expiration of the timer; transmitting, by the wireless apparatus in response to reception of the downlink transmission, an acknowledgement and discontinuing reception before the timer has expired; and adjusting, by the wireless apparatus, an uplink transmission time for a communication to the networking device based on a determined amount of time drift. - View Dependent Claims (19, 20, 21, 22, 23, 24)
