If the UE signals a value in the "E-DCH physical layer category extension 2" IE, it shall signal an "E-DCH physical
layer category" of 6.
If the UE supports 64QAM in the uplink, the UE shall signal a value of 10 in the "E-DCH physical layer category
extension 3" IE.
If the UE supports UL MIMO, the UE shall signal a value of 11 in the "E-DCH physical layer category extension 3" IE.
If the UE supports 64QAM in the uplink and UL MIMO, the UE shall signal a value of 12 in the "E-DCH physical layer
category extension 3" IE
If the UE signals a value in the "E-DCH physical layer category extension 3", it shall signal an "E-DCH physical layer
category" of 7.
8.1.6.3 Reception of a UE CAPABILITY INFORMATION message by the UTRAN
Upon reception of a UE CAPABILITY INFORMATION message, the UTRAN should transmit a UE CAPABILITY
INFORMATION CONFIRM message on the downlink DCCH using UM or AM RLC. After the UE CAPABILITY
INFORMATION CONFIRM message has been submitted to the lower layers for transmission, the procedure is
complete.
If the received UE CAPABILITY INFORMATION message indicates capabilities that would be insufficient for the UE
to continue in an ongoing service, the UTRAN may reconfigure the bearers for the ongoing service. In such a case, if
the UTRAN does not perform such a reconfiguration, it should set the IE "Acceptance of requested change of
capability" to "Refused" in the UE CAPABILITY INFORMATION CONFIRM message.
8.1.6.4 Reception of the UE CAPABILITY INFORMATION CONFIRM message by
the UE
Upon reception of a UE CAPABILITY INFORMATION CONFIRM message, the UE shall:
1> stop timer T304;
1> if there is an entry for the UE CAPABILITY ENQUIRY message is present in the table "Accepted transactions"
in the variable TRANSACTIONS:
2> clear that entry.
1> if the IE "Acceptance of requested change of capability" is included and set to "Accepted":
2> update its variable UE_CAPABILITY_TRANSFERRED with the UE capabilities it has last transmitted to
the UTRAN during the current RRC connection.
1> if the IE "Acceptance of requested change of capability" is included and set to "Accepted with reconfiguration to
follow":
2> when a reconfiguration message with the flag "Reconfiguration in response to requested change of UE
capability" set to TRUE, update its variable UE_CAPABILITY_TRANSFERRED with the UE capabilities it
has last transmitted to the UTRAN during the current RRC connection;
2> if a reconfiguration message with the flag "Reconfiguration in response to requested change of UE
capability" set to TRUE it is not received by the UE within a time determined by the implementation, the UE
shall consider the change of capabilities to be refused by the UTRAN.
1> if the IE "Acceptance of requested change of capability" is included and set to "Refused":
2> consider the request for a change of capabilities to be refused;
2> wait at least 300 seconds before transmitting another such request.
1> clear the variable UE_CAPABILITY_REQUESTED;
1> and the procedure ends.
