Abstract
A time slot assignment arrangement for ultralow power devices in a wireless communication network is disclosed. The time slot assigned to ultralow power device wakeup frame is identified as ultralow power timeslot using various indicators. The ultralow power timeslot is assigned as contention based timeslot allowing ultralow power devices in the wireless network to extend the interval for synchronizing with the network overcoming the short synchronization interval requirements of wireless communication network resulting in significant improvement in battery life by preserving the power needed for frequent synchronization with the wireless communication network.
Claims20
A device comprising:
- a transceiver;
- and
- a processor coupled to the transceiver and configured to:
- determine a wireless network synchronization time period, and
- identify a timeslot for transmitting a frame as ultralow power timeslot when a synchronization time period of the wireless network is shorter than a predetermined time period.
A method comprising:
- determining, a wireless network synchronization time period;
- and
- identifying, a timeslot for transmitting a frame as ultralow power timeslot when a synchronization time period of the wireless network is shorter than a predetermined time period.
A network element comprising:
- a transceiver configured to transmit and receive data in a wireless network;
- and
- a processor coupled to the transceiver and configured to:
- determine data transmission time of a network device, and
- identify a timeslot for receiving a frame from the network device as ultralow power timeslot when a synchronization time of the wireless network is shorter than a data transmission time interval of the network device.
