Channel time allocation method in WPAN
First Claim
1. A channel time allocation method in a wireless network which is synchronized by a synchronization signal broadcasted from a coordinator, comprising the steps of:
- a plurality of data devices linked to the wireless network each transmitting to the coordinator a command requesting a first channel time necessarily required and a second channel time selectively required according to a type of data to be transmitted;
the coordinator allocating a channel time which includes a channel time allocation (CTA) period corresponding to each first channel time requested by the plurality of the devices, and a shared CTA period corresponding to each second channel time requested by the plurality of the devices and to be shared and used by the plurality of the devices; and
broadcasting to the plurality of the devices the synchronization signal to which information of the allocated channel time is inserted.
