RRI Gain Parameters

Last updated: November 10, 2006

This section is only applicable to the lab application and to a test application with the required feature license.

The RRI Channel Gain parameters include seven settings: RRIChannelGainPreTransition0, RRIChannelGainPostTransition0, RRIChannelGainPreTransition1, RRIChannelGainPostTransition1, RRIChannelGainPreTransition2, RRIChannelGainPostTransition2, and RRIChannelGainPreTransition3. When the current physical layer subtype is subtype 2 (see Release A Physical Layer Subtype ), these parameters used with the current T2P Transition value (see T2P Transition Settings ) and current subpacket being transmitted determine the current R-RRI Channel gain (relative to R-Pilot channel).

The table below shows when the different RRI Channel Gain parameters are used to set the gain of the RRI Channel. The RRIChannelGainPreTransition X indicates the ratio of the power level of the R-RRI Channel relative to the power level of the R-Pilot Channel for those subpackets transmitted prior to the T2P Transition when T2P Transition value is X subpacket(s). For details on the T2P Transition, see T2P Transition Settings .

RRI Channel Gain Parameters

T2P Transition Value	RRI Channel Gain Parameters Used for Subpacket X Transmission
	Subpacket 0	Subpacket 1	Subpacket 2	Subpacket 3
0	RRIChannelGainPreTransition0	RRIChannelGainPostTransition0	RRIChannelGainPostTransition0	RRIChannelGainPostTransition0
1	RRIChannelGainPreTransition1	RRIChannelGainPreTransition1	RRIChannelGainPostTransition1	RRIChannelGainPostTransition1
2	RRIChannelGainPreTransition2	RRIChannelGainPreTransition2	RRIChannelGainPreTransition2	RRIChannelGainPostTransition2
3	RRIChannelGainPreTransition3	RRIChannelGainPreTransition3	RRIChannelGainPreTransition3	RRIChannelGainPreTransition3

In Active Cell operating mode the RRI Channel Gain parameters are "Configurable Attributes" for the Subtype 3 Reverse Traffic Channel MAC Protocol. They are negotiated with the AT in the RRIChannelPowerParameters attribute during Session Negotiate State . When a session is open, changing these settings will result in a session re-negotiation. When a connection is open, changing these settings will result in the connection closed. You will have to re-open the connection. To determine when the Subtype 3 Reverse Traffic Channel MAC Protocol is active, see Current Physical Layer Subtype and Associated Protocols .

The power level of the R-RRI channel is determined by the current R-RRI Channel gain (see Expected Power ).
