2> for 1.28 Mcps TDD, when performing reception on signalling radio bearer before RAB has been established,
3> if MAC-ehs is not configured,
4> use the table of transport block size for the HS-DSCH physical layer category 1 as specified in [15],
and consider the UE capability "Total number of soft channel bits in HS-DSCH" equal to that of the
HS-DSCH physical layer category 1 as specified in [35].
3> else,
4> use the table of transport block size for the HS-DSCH physical layer category 9 as specified in [15],
and consider the UE capability "Total number of soft channel bits in HS-DSCH" equal to that of the
HS-DSCH physical layer category 9 as specified in [35].
NOTE 4: 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 descibed above, when performing
scheduling and signalling the control information on HS-SCCH, as it is not possible for Node B to be
aware of the UE's HSDPA capability category during this period.
1> perform HS-DSCH reception procedures according to the stored HS-PDSCH configuration as stated in:
2> subclause 8.6.3.1b for the IE "H-RNTI";
2> subclause 8.6.5.6b for the IE "HARQ info";
2> subclause 8.6.6.34 for the IE "Measurement Feedback Info".
1> use the relevant CQI reporting table as stated in subclause 8.5.44.
In CELL_DCH, whenever the variable HS_DSCH_RECEPTION is set to FALSE, the UE shall:
1> not perform HS-SCCH reception procedures;
1> not perform HS-DSCH reception procedures.
For FDD and CELL_DCH state, determine the value for the SECONDARY_CELL_HS_DSCH_RECEPTION variable
and take the corresponding actions as described in subclause 8.5.51.
8.5.26 Service prioritisation
If the UE detects an MBMS service reception inability as specified in subclause 8.5.30, the UE may:
1> request upper layers to prioritise the services and to initiate release of non- prioritised services that may cause
interruption in the reception of the prioritised services;
1> if reception of the prioritised MBMS service is inhibited by one or more MBMS service(s) provided via a p-t-p
radio bearer:
2> request UTRAN to terminate these MBMS service(s) using the MBMS MODIFICATION REQUEST
message as specified in subclause 8.7.6.
NOTE:
The termination of MBMS services is performed by RRC procedures, while clearing of non- MBMS
services is performed by upper layers.
8.5.27 MBMS frequency selection
The UE shall perform the MBMS frequency layer selection procedure upon receiving the IE "MBMS Preferred
frequency information", when specified explicitly e.g. as in subclause 8.6.9.2, or when the priority for an MBMS
service as indicated by upper layers changes.
The UE shall:
1> if there exist two or more preferred frequencies for services included in variable
