2.6.4.1.1.1 Forward Traffic Channel Power Control Initialization

To initialize Forward Traffic Channel power control, the mobile station shall set TOT_FRAMESs, BAD_FRAMESs, DCCH_TOT_FRAMESs, and DCCH_BAD_FRAMESs to zero. The mobile station shall initialize the frame counters SCH_TOT_FRAMESs and SCH_BAD_FRAMESs for each assigned Supplemental Channel to zero. The mobile station shall initialize FOR_SCH_FER_REPs to zero.
2.6.4.1.1.2 Processing the Power Control Parameters Message

The mobile station shall store the following parameters from the Power Control Parameters Message:

• Power control reporting threshold (PWR_REP_THRESHs = PWR_REP_THRESHr)

• Power control reporting frame count (PWR_REP_FRAMESs = PWR_REP_FRAMESr)

• Threshold report mode indicator


(PWR_THRESH_ENABLEs = PWR_THRESH_ENABLEr)

• Periodic report mode indicator


(PWR_PERIOD_ENABLEs = PWR_PERIOD_ENABLEr)

• Power report delay (PWR_REP_DELAYs = PWR_REP_DELAYr)

The mobile station shall set TOT_FRAMESs and BAD_FRAMESs to zero.

2.6.4.1.1.3 Processing the Power Control Message

The mobile station shall send a Mobile Station Reject Order with the ORDQ field set to ‘00000110’ (message requires a capability that is not supported by the mobile station) if any of the following conditions are detected:

• If the mobile station does not support any Radio Configuration greater than 2 and FPC_MODEr is not supported by the mobile station.

• If the mobile station does not support Supplemental Channel and FPC_MODEr is set to the ‘001’ or ‘010’.

• If PWR_CNTL_STEPr corresponds to a power control step size (see 2.1.2.3.2 of TIA/EIA/IS-2000-2) is not supported by the mobile station.

The mobile station shall send a Mobile Station Reject Order with the ORDQ field set to ‘00000111’ (message cannot be handled by the current mobile station configuration) if any of the following conditions are detected:

• FPC_PRI_CHANr is set to ‘1’ and only the Fundamental Channel is assigned.

• FPC_PRI_CHANr is set to ‘0’ and only the Dedicated Control Channel is assigned.

If none of the above conditions are true, the mobile station shall process the message as follows at the action time (see 2.6.4.1.5) specified in the message:

• The mobile station shall store the power control step size (PWR_CNTL_STEPs = PWR_CNTL_STEPr).

• If FPC_INCLr is equal to ‘1’, the mobile station shall perform the following:

– The mobile station shall set FPC_MODEs = FPC_MODEr.

– The mobile station shall set FPC_PRI_CHANs to FPC_PRI_CHANr

– If FPC_OLPC_FCH_INCL is equal to ‘1’, the mobile station shall:

+ Set FPC_FCH_FERs to FPC_FCH_FERr.

+ If FPC_FCH_MIN_SETPTr is not equal to ‘11111111’, set FPC_FCH_MIN_SETPTs to FPC_FCH_MIN_SETPTr; otherwise, set FPC_FCH_MIN_SETPTs to FPC_FCH_CURR_SETPTs.

+ If FPC_FCH_MAX_SETPTr is not equal to ‘11111111’, set FPC_FCH_MAX_SETPTs to FPC_FCH_MAX_SETPTr; otherwise, set FPC_FCH_MAX_SETPTs to FPC_FCH_CURR_SETPTs.

– If FPC_OLPC_DCCH_INCL is equal to ‘1’, the mobile station shall:

+ Set FPC_ DCCH_FERs to FPC_DCCH_FERr.

+ If FPC_DCCH_MIN_SETPTr is not equal to ‘11111111’, set FPC_DCCH_MIN_SETPTs to FPC_DCCH_MIN_SETPTr; otherwise, set FPC_DCCH_MIN_SETPTs to FPC_DCCH_CURR_SETPTs.

+ If FPC_DCCH_MAX_SETPTr is not equal to ‘11111111’, set FPC_DCCH_MAX_SETPTs to FPC_DCCH_MAX_SETPTr; otherwise, set FPC_DCCH_MAX_SETPTs to FPC_DCCH_CURR_SETPTs.

– If FPC_OLPC_SCH_M_INCL is equal to ‘1’, the mobile station shall:

+ Set FPC_SEC_CHANs to FPC_SEC_CHANr.

+ Set FPC_SCH_FERs[FPC_SEC_CHANs] to FPC_SCH_M_FERr.

+ If FPC_SCH_MIN_M_SETPTr is not equal to ‘11111111’, set FPC_SCH_MIN_SETPTs[FPC_SEC_CHANs] to FPC_SCH_MIN_M_SETPTr; otherwise, set FPC_SCH_MIN_SETPTs[FPC_SEC_CHANs] to FPC_SCH_CURR_M_SETPTs.

+ If FPC_SCH_MAX_M_SETPTr is not equal to ‘11111111’, set FPC_SCH_MAX_SETPTs[FPC_SEC_CHANs] to FPC_SCH_MAX_M_SETPTr; otherwise, set FPC_SCH_MAX_SETPTs[FPC_SEC_CHANs] to FPC_SCH_CURR_M_SETPTs.

– If NUM_SUPr is not equal to ‘00’, for each Supplemental Channel included in the message, the mobile station shall:

+ Set SCH_IDs to SCH_IDr.

+ Set FPC_SCH_FERs[SCH_IDs]  to FPC_SCH_FERr.

+ If FPC_SCH_MIN_ SETPTr is not equal to ‘11111111’, set FPC_SCH_MIN_SETPTs[SCH_IDs] to FPC_SCH_MIN_SETPTr; otherwise, set FPC_SCH_MIN_SETPTs[SCH_IDs] to FPC_SCH_CURR_SETPTs.

+ If FPC_SCH_MAX_SETPTr is not equal to ‘11111111’, set FPC_SCH_MAX_SETPTs[SCH_IDs] to FPC_SCH_MAX_SETPTr; otherwise, set FPC_SCH_MAX_SETPTs[SCH_IDs] to FPC_SCH_CURR_SETPTs.

– If FPC_THRESH_INCL is equal to ‘1’, the mobile station shall set FPC_SETPT_THRESHs to  FPC_SETPT_THRESHr.

– If FPC_THRESH_SCH_INCL is equal to ‘1’, the mobile station shall set FPC_SETPT_THRESH_SCHs to  FPC_SETPT_THRESH_SCHr

• If RPC_INCLr is equal to ‘1’ and the mobile station supports any Radio Configuration greater than 2, the mobile station shall perform the following:


    – If RPC_ADJ_REC_TYPE is equal to ‘0000’, the mobile station shall update the Reverse Channel Adjustment Gain Table (see 2.1.2.3.3 of TIA/EIA/IS-2000-2) containing an offset relative to the Reverse Pilot Channel power for each reverse link code channel received in this message.

    – If RPC_ADJ_REC_TYPE is equal to ‘0001’ or ‘0010’, the mobile station shall update the Reverse Link Attribute Adjustment Gain Table (see 2.1.2.3.3 of TIA/EIA/IS-2000-2) containing an offset relative to the Reverse Pilot Channel power for each transmission rate, frame length, coding type received in this message.
