8.2.3 Framing

This PHY specification operates in a framed format (6.2.7). Within each frame are a downlink subframe and an uplink subframe. The downlink subframe begins with information necessary for frame synchronization and control. In the TDD case, the downlink subframe comes first, followed by the uplink subframe. In the FDD case, uplink transmissions occur concurrently with the downlink frame.

Each SS shall attempt to receive all portions of the downlink except for those bursts whose burst profile is either not implemented by the SS or is less robust than the SS’s current operational downlink burst profile. Half-duplex SSs shall not attempt to listen to portions of the downlink coincident with their allocated uplink transmission, if any, adjusted by their Tx time advance.

8.2.3.1 Supported frame durations

Table 84 indicates the supported frame durations.
