1> For FDD:

2> the UE has stored the following IEs:

– IE "HARQ info for E-DCH";

– IE "E-DCH info", including the IE "E-DPCCH info" and the IE "E-DPDCH info";

– one of the radio links in the active set is configured as the 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> For TDD:

2> for non-scheduled transmission, the UE has stored the following IEs:

1> set the variable E_DCH_TRANSMISSION to FALSE;

1> stop any E-AGCH and E-HICH reception procedures;

1> clear the variable E_RNTI;

1> act as if the IE "MAC-es/e reset indicator" was received and set to TRUE;

1> release all E-DCH HARQ resources;

2> if MAC-hs is configured:

3> the UE behaviour is not specified.

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

2> perform E-DPCCH transmission procedures according to the stored E-DPCCH configuration as stated in:

3> subclause 8.6.6.37 for the IE "E-DPCCH Info".

2> perform E-DPDCH transmission procedures according to the stored E-DPDCH configuration as stated in:

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

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

3> subclause 8.6.6.37 for the IE "E-DPDCH Info".

2> inclusion of MAC-d PDU’s in a MAC-e or MAC-i PDU for logical channels belonging to a MAC-d flow for which the IE "Non-scheduled transmission grant info" is configured shall:

3> obey the scheduling and size restrictions as specified for that MAC-d flow (see subclause 8.6.5.18).

2> inclusion of MAC-d PDU’s in a MAC-e or MAC-i PDU for logical channels belonging to a MAC-d flow for which the IE "Scheduled transmission grant info" is configured shall:

3> be performed in accordance with the received scheduling grant on E-AGCH/E-RGCH (see [15]); and

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

1> For TDD:

2> if scheduled transmission is configured, perform E-AGCH reception procedures according to the stored E-AGCH configuration as stated in:

3> subclause 8.6.3.14 for the IE "New Primary E-RNTI".

2> Perform E-HICH reception;

2> for 3.84/7.68 Mcps TDD, perform E-RUCCH transmission procedures according to the stored E-RUCCH configuration as stated in:

3> subclause 8.6.6.37 for the IE "E-RUCCH Info".

2> for 1.28 Mcps TDD, if scheduled transmission is configured, perform E-RUCCH transmission procedure according to the stored PRACH configuration (see [60]) and the stored E-RUCCH configuration as stated in:

3> subclause 8.6.6.37 for the IE "E-RUCCH Info".

NOTE 1: The PRACH configuration is signalled directly to the UE in "E-RUCCH Info" IE in case of E-DCH serving cell change.

2> Perform E-PUCH transmission procedures according to the stored E-PUCH configuration as stated in:

3> subclause 8.6.6.37 for the IE "E-PUCH Info".

2> inclusion of MAC-d PDU’s in a MAC-e or MAC-i PDU for logical channels belonging to a MAC-d flow for which the IE "Non-scheduled transmission grant info" is configured shall:

3> obey the scheduling and size restrictions as specified for that MAC-d flow (see subclause 8.6.5.18).

2> inclusion of MAC-d PDU’s in a MAC-e or MAC-i PDU for logical channels belonging to a MAC-d flow for which the IE "Scheduled transmission grant info" is configured shall:

3> be performed in accordance with the received scheduling grant on E-AGCH (see [15]); and

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

2> obtain and format the appropriate information on E-UCCH (see [15]).

2> for 1.28 Mcps TDD, when performing transmission on signalling radio bearer before RAB has been established,

3> if MAC-i/is is not configured,

4> use the tables of transport block size for the E-DCH physical layer category 1 as specified in [15].

3> else,

4> use the tables of transport block size for the E-DCH physical layer category 3 as specified in [15].

NOTE 2: For 1.28 Mcps TDD, when performing transmission on signalling radio bearer before RAB has been established, UTRAN should use the same rules with the UE as described above, when performing configuration, scheduling and reading the control information on E-UCCH, as it is not possible for Node B to be aware of the UE’s E-DCH capability category during this period.

1> For FDD and CELL_DCH state, determine the value for the SECONDARY_CELL_E_DCH_TRANSMISSION and take the corresponding actions as described in subclause 8.5.58.

1> For 1.28Mcps TDD and CELL_DCH state, determine the value for the MULTI_CARRIER_ E_DCH_TRANSMISSION and take the corresponding actions as described in subclause 8.5.62.

Whenever the variable E_DCH_TRANSMISSION is set to FALSE, the UE in CELL_DCH state shall:

1> delete any stored E-AGCH, E-RGCH and E-HICH information for all radio links;

1> not perform E-AGCH, E-HICH and/or E-RGCH reception procedures;

1> not perform E-DPCCH, E-DPDCH, E-RUCCH and/or E-PUCH transmission procedures.

1> For FDD, determine the value for the SECONDARY_CELL_E_DCH_TRANSMISSION and take the corresponding actions as described in subclause 8.5.58.

1> For 1.28Mcps TDD, determine the value for the MULTI_CARRIER_ E_DCH_TRANSMISSION and take the corresponding actions as described in subclause 8.5.62.
