SYNCHRONIZATION VIA ADDITIONAL BEACON TRANSMISSION
First Claim
1. A method, comprising:
- transmitting a beacon signal from an apparatus during a periodic time interval in which communication is permitted in the wireless network;
receiving a late beacon signal in the apparatus, the beacon signal being deemed late due to being received after a certain time measured from the beginning of the periodic time interval; and
in response to receiving the late beacon signal, initiating transmission of an additional beacon signal.

Abstract
Apparatuses may stay synchronized with a wireless network utilizing a diluted beacon interval that is an integer multiple of a network beacon period signal being transmitted at a set interval. Diluted beacon intervals may reduce communication burden, but may also cause periods of inactivity that allow apparatuses to become unsynchronized with the network. Apparatuses may be active in the network during an awake window wherein a beacon may be transmitted. A set time may also be set during the awake window may delineate a period of time after which any beacon signal received from another apparatus is deemed to be late. Receiving late beacon signals in the apparatus may trigger the transmission of additional beacon signals to help the other apparatuses that transmitted late beacons become resynchronized with the network.

7. A computer program product comprising computer executable program code recorded on a computer readable storage medium, the computer executable program code comprising:
-
code configured to cause an apparatus to transmit a beacon signal from an apparatus during a periodic time interval in which communication is permitted in the wireless network; code configured to cause an apparatus to receive a late beacon signal in the apparatus, the beacon signal being deemed late due to being received after a certain time measured from the beginning of the periodic time interval; and code configured to, in response to receiving the late beacon signal, cause an apparatus initiate transmission of an additional beacon signal. - View Dependent Claims (8, 9, 10, 11, 12)

13. An apparatus, comprising:
-
at least one processor; and at least one memory including executable instructions, the at least one memory and the executable instructions being configured to, in cooperation with the at least one processor, cause the device to perform at least the following; transmit a beacon signal during a periodic time interval in which communication is permitted in the wireless network; receive a late beacon signal in the apparatus, the beacon signal being deemed late due to being received after a certain time measured from the beginning of the periodic time interval; and in response to receiving the late beacon signal, initiate transmission of an additional beacon signal. - View Dependent Claims (14, 15, 16, 17, 18)
