Framing and Channel Multiplexing
[OpenAirInterface Physical Layer (PHY) Specifications]

Modules
	TTI and Modulation Parameters
	The physical layer uses OFDM symbols organized into frames (corresponding to TTIs) of complex baseband samples at a sampling rate of samples/s.
	Clusterhead Synchronization Channel (P-CHSCH,S-CHSCH) Signaling Format
	The clusterhead synchronization channel is a signaling channel generated in the PHY layer and is comprised of samples, or the equivalent of one OFDM symbols.
	Clusterhead Broadcast Channel (P-CHBCH,S-CHBCH) Signaling Format
	The CHBCH is the signaling channel used by the DLC for passing basic protocol information from the clusterhead to the nodes in its cluster.
	Random-Access Channel (RACH) Signaling Format
	The RACH is a signaling channel used only during the association phase of a node and for other management services.
	Scheduled-Access (SACH) and Scheduled-Access Control Channel (SACCH) Signaling Format
	The SACH/SACCH is a multiplexed resource containing both signaling information (Scheduled Access Control CHannel) and user plane traffic (Scheduled Access CHannel).
