Figure 8.2.11-1: Physical channel reconfiguration failure in case of runtime configuration error
8.2.11.1 General
The physical channel reconfiguration failure procedure is used to indicate to the network a runtime configuration error in the UE.
8.2.11.2 Runtime error due to overlapping compressed mode configurations
When the UE has received from the UTRAN the configurations of several compressed mode transmission gap pattern sequences, and if several of these patterns are to be simultaneously active, the UE shall check to see if these simultaneously active transmission gap pattern sequences create transmission gaps in the same frame. An illegal overlap is created if two or more transmission gap pattern sequences create transmission gaps in the same frame, irrespective of the gaps are created in uplink or downlink.
If the parallel transmission gap pattern sequences create an illegal overlap, the UE shall:
1> delete the overlapping transmission gap pattern sequence configuration stored in the variable TGPS_IDENTITY, which is associated with the highest value of IE "TGPSI";
1> transmit a PHYSICAL CHANNEL RECONFIGURATION FAILURE message on the DCCH using AM RLC, setting the information elements as specified below:
2> not include the IE "RRC transaction identifier";
2> set the cause value in IE "failure cause" to value "compressed mode runtime error".
1> terminate the inter-frequency and/or inter-RAT measurements corresponding to the deleted transmission gap pattern sequence;
1> when the PHYSICAL CHANNEL RECONFIGURATION FAILURE message has been submitted to lower layers for transmission:
2> the procedure ends.
