TIA-1185.300-A:2015

General Overview

The MAC Layer contains the rules governing operation of the
Control Channel, the Access Channel, the Forward Traffic Channel,
and the Reverse Traffic Channel.

This section presents the protocols for the MAC Layer. Each of
these protocols can be independently negotiated at the beginning of
the session.

The MAC Layer contains the following protocols:

• Control Channel MAC Protocol: This protocol builds Control
  Channel MAC Layer packets out of one or more Security Layer
  packets, contains the rules concerning access network transmission
  and packet scheduling on the Control Channel, access terminal
  acquisition of the Control Channel, and access terminal Control
  Channel MAC Layer packet reception. This protocol also adds the
  access terminal address to transmitted packets.
• Access Channel MAC Protocol: This protocol contains the rules
  governing access terminal transmission timing and power
  characteristics for the Access Channel. 
• Forward Traffic Channel MAC Protocol: This protocol contains
  the rules governing operation of the Forward Traffic Channel. It
  dictates the rules the access terminal follows when transmitting
  the Channel Quality Indicator Channel, along with the rules the
  access network uses to interpret this channel. The protocol
  supports variable rate operation of the Forward Traffic
  Channel. 
• Reverse Traffic Channel MAC Protocol: This protocol contains
  the rules governing operation of the Reverse Traffic Channel. It
  dictates the rules the access terminal follows to assist the access
  network in acquiring the Reverse Traffic Channel. It also indicates
  the rules the access terminal and the access network use to select
  the transmission rate used over the Reverse Traffic
  Channel.
