FTC MAC Parameters

DRC Supervision Timer

The Access Terminal shall perform supervision on the DRC as follows:

• The Access Terminal shall set the DRC supervision timer for (DRCSupervisionTimer x 10) + 240 ms when its Tentative DRC is a null rate DRC.
• The Access Terminal shall disable the timer if the DRC supervision timer is active and any of the following conditions is true:
  • the Access Terminal's tentative DRC indicates a non-null rate
  • the Access Terminal successfully receives a Forward Traffic Channel packet or a Control Channel packet.
• If the DRC supervision timer expires, the Access Terminal shall disable the Reverse Traffic Channel transmitter and set the Reverse Traffic Channel Restart timer.
• If the Access Terminal generates consecutive Tentative DRC values that correspond to non-null rates or the Access Terminal successfully receives a Forward Traffic Channel packet or a Control Channel packet, the Access Terminal shall disable the Reverse Traffic Channel Transmitter.
• If the Reverse Traffic Channel Restart timer expires, the Access Terminal shall return a SupervisionFailed indication and transition to the Inactive State.

Minimum Continuation Span (subpackets)

Minimum Continuation Span is a parameter for configuring the DRC channel. It can be set to 1 - 16 subpackets.

A slot t is defined to be a continuation of an earlier slot s, if the following conditions are met:

• The Access Terminal is a potential target of a packet for which the reception began in slot s.
• The slot t is in the same forward link interlace as the slot s.
• s < t < s+4 x min(N1, N2, MinimumContinuationSpan), where N1 denotes the Nominal Transmit Duration of the packet whose reception began in slot s and N2 denotes the Span of DRC index corresponding to the DRC value that is in effect during slot s.
• Prior to slot t, the Access Network has not received a positive acknowledgment for the packet for which the reception began in slot s.

If the Access Terminal is a potential target of a packet transmitted by a sector starting in slot s, the Access Network shall not transmit another packet from the same Forward Link Data Source to the Access Terminal in any slot t that is a continuation of slot s.
