1> the UE has stored IE "Secondary serving E-DCH cell info" and IE "Secondary E-DCH info common";

1> one of the radio links in the secondary E-DCH active set is configured as the secondary serving E-DCH radio link, and for this radio link the UTRAN has configured the IE "E-HICH configuration" and the IE "E-AGCH info".

1> either the Primary E-RNTI or the Secondary E-RNTI or both the Primary and the Secondary E-RNTI are included in the stored IE "Secondary serving E-DCH cell info";

1> if the UE does not support dual cell E-DCH transmission with the DPDCH channel:

2> the IE "Number of DPDCH" in the IE "Uplink DPCH info" is set to 0.

1> the variable E_DCH_TRANSMISSION is set to TRUE;

1> the i-th entry in the variable SECONDARY_CELL_HS_DSCH_RECEPTION is set to TRUE, where the i-th entry is the position of the first non-empty entry in the variable DOWNLINK_SECONDARY_CELL_INFO;

If any of the above conditions are not met and the variable SECONDARY_CELL_E_DCH_TRANSMISSION is set to TRUE, the UE shall:

1> set the variable SECONDARY_CELL_E_DCH_TRANSMISSION to FALSE;

1> stop any F-DPCH, E-AGCH, E-HICH and E-RGCH reception procedures on the downlink frequency associated with the secondary uplink frequency;

1> stop any DPCCH, E-DPCCH and E-DPDCH transmission procedures on the secondary uplink frequency;

1> release all E-DCH HARQ resources for the secondary uplink frequency;

1> do not configure "TSN field extension" for the MAC-i/is entity;

1> reset the MAC-i/is entity [15];

1> clear any stored IE "Secondary serving E-DCH cell info" and IE "Secondary E-DCH info common";

1> remove all the radio links associated to the secondary E-DCH active set.

1> for FDD, if the IE "Uplink CLTD info FDD" is stored in the UE:

2> determine the value for the UPLINK_CLTD_TRANSMISSION variable and take the corresponding actions as described in subclause 8.5.69.

1> for FDD, if the IE "Uplink OLTD info FDD" is stored in the UE:

2> determine the value for the UPLINK_OLTD_TRANSMISSION variable and take the corresponding actions as described in subclause 8.5.70.

If all of the above conditions are met and the variable SECONDARY_CELL_E_DCH_TRANSMISSION is set to FALSE, the UE shall:

1> set the variable SECONDARY_CELL_E_DCH_TRANSMISSION to TRUE;

1> configure "TSN field extension" for the MAC-i/is entity;

1> reset the MAC-i/is entity [15].

1> for FDD, if the IE "Uplink CLTD info FDD" is stored in the UE:

2> determine the value for the UPLINK_CLTD_TRANSMISSION variable and take the corresponding actions as described in subclause 8.5.69.

1> for FDD, if the IE "Uplink OLTD info FDD" is stored in the UE:

2> determine the value for the UPLINK_OLTD_TRANSMISSION variable and take the corresponding actions as described in subclause 8.5.70.

Whenever the variable SECONDARY_CELL_E_DCH_TRANSMISSION is set to TRUE, and the secondary uplink frequency is an activated uplink frequency, the UE shall:

1> perform E_AGCH reception procedures on the secondary serving E-DCH cell according to the stored E_AGCH configuration as stated in:

2> subclause 8.6.3.14 for the IE "Primary E-RNTI" and the IE "Secondary E-RNTI" for secondary serving E-DCH cell.

1> perform E-HICH reception procedures for all radio links in the secondary E-DCH active set;

1> perform E-RGCH reception procedures for all radio links in the secondary E-DCH active set for which an E-RGCH configuration has been provided;

1> perform uplink DPCCH transmission on the secondary uplink frequency according to the stored uplink DPCH info configuration as stated in:

2> subclause 8.6.6.6 for the IE "Uplink DPCH info";

2> subclause 8.6.6.49 for the IE "Uplink Secondary Cell Info FDD".

1> perform E-DPCCH transmission procedures on the secondary uplink frequency according to the stored E-DPCCH configuration as stated in:

2> subclause 8.6.6.37 for the IE "E-DPCCH Info";

2> subclause 8.6.6.49 for the IE "Uplink Secondary Cell Info FDD".

1> perform E-DPDCH transmission procedures on the secondary uplink frequency according to the stored E-DPDCH configuration as stated in:

2> subclause 8.6.5.16 for the IE "E-DCH Transmission Time Interval";

2> subclause 8.6.5.17 for the IE "HARQ info for E-DCH";

2> subclause 8.6.6.37 for the IE "E-DPDCH Info";

2> subclause 8.6.6.49 for the IE "Uplink Secondary Cell Info FDD".

1> inclusion of MAC-d PDU’s in a MAC-i PDU for logical channels on the secondary uplink frequency shall:

2> be performed in accordance with the received scheduling grant on E-AGCH/E-RGCH (see [15]) on the downlink frequency associated with the secondary uplink frequency; and

2> obey the scheduling restrictions as specified for scheduled transmissions (see subclause 8.6.6.37).

Whenever the variable SECONDARY_CELL_E_DCH_TRANSMISSION is set to FALSE, or the secondary uplink frequency is not an activated uplink frequency, the UE shall:

1> not perform F-DPCH, E-AGCH, E-HICH and E-RGCH reception procedures on the downlink frequency associated with the secondary uplink frequency;

1> not perform DPCCH, E-DPCCH and E-DPDCH transmission procedures on the secondary uplink frequency.
