Implicit exchange of channel information for un-slotted channel hopping networks

A method of un-slotted channel hopping (USCH) network synchronization, the method comprising:

• receiving, by a first device from a low power device, a poll frame exclusive of a unicast schedule information element (US-IE) on a current channel of the first device;
• computing, by the first device an updated receive channel based on the current channel, after receiving the poll frame;
• and
• receiving, by the first device from the low power device, data, on the updated receive channel.

A low power device, comprising:

• a processor;
• and
• a non-transitory computer readable storage medium storing a program for execution by the processor, the program including instructions to:
• obtain an initial receive channel of a second device, using a channel hopping sequence;
• transmit, to the second device, a poll frame exclusive of a unicast schedule information element (US-IE), on the initial receive channel of the second device;
• move, by the low power device, to an updated receive channel, by determining the updated receive channel based on the initial receive channel;
• and
• receive, from the second device, a data frame on the updated receive channel.
