8.3.32 Secondary UL Frequency Reporting [FDD]

25.4233GPPRelease 17TSUTRAN Iur interface Radio Network Subsystem Application Part (RNSAP) signalling

8.3.32.1 General

The purpose of this procedure is to inform the DRNS about the activation state of the secondary UL frequency of the UE in Dual Cell E-DCH operation or change the activation state of the secondary UL frequency of the UE in Dual Cell E-DCH operation when E-DCH decoupling is configured.

This procedure shall use the signalling bearer connection for the relevant UE Context.

8.3.32.2 Successful Operation

Figure 26R: Secondary UL Frequency Reporting procedure

The Secondary UL Frequency Reporting procedure is initiated by sending the SECONDARY UL FREQUENCY REPORT message from the SRNC to the DRNC.

The Activation Information IE defines the local activation state of the Secondary uplink frequency of the UE in Dual Cell E-DCH operation, or the change request of activation state of the Secondary uplink frequency of the UE in Dual Cell E-DCH operation when E-DCH decoupling is configured.

– If the value of Uu Activation State IE is “Activated”: the DRNS shall if supported use this information for resource allocation operation of the secondary E-DCH radio link(s), F-DPCH transmission and DPCCH detection.

– If the value of Uu Activation State IE is “De-Activated”: the DRNS shall if supported use this information for release of the related resources for the secondary E-DCH radio link(s), cease of F-DPCH transmission and DPCCH detection.

– If the value of Uu Activation State IE is “Change Request”: the DRNS shall if supported change the local activation state of the Secondary uplink frequency of the UE in Dual Cell E-DCH operation when E-DCH decoupling is configured.
