| (54) | Synchronization for data transfer between physical layers |
| (57) Various embodiments relate to a system and related method that enable transfer of
control and data messages in a wireless communication network between devices operating
on different physical layers (PHY). Control data and/or isochronous data and/or asynchronous
data may be transferred between devices that operate on different physical layers
through a bridging device, while minimizing latency and buffering. The bridging device
may contain interfaces that may operate on each of the respective physical layers.
A first interface may receive a first superframe from a device in a first physical
layer (PHY1) and may generate an equivalent second superframe to transmit to a second
device on a second physical layer (PHY2). The bridging device may also synchronize
the time slots and reference clocks for communication protocols on each physical layer
to further minimize latency and buffering during the transfer of control and data
messages via communication frames within these superframes.
