10 in case first out of sync T300, T301, T304 or T311 is not running In this case, the UE resumes the RRC >10 ms T310 running connection without explicit signaling, i.e. the UE resumes the entire radio resource configuration Upon receiving N311 consecutive 'in-sync' Periods in time where neither 'in-sync' nor indications from lower layers 'out-of-sync' is reported by layer 1 do not while T310 is running, the UE affect the evaluation of the number of stops timer T310 consecutive 'in-sync' or 'out-of-sync' indications Figure 12.26 Out-of-sync and in-sync evaluation threshold, Qin, is defined as the level at which the downlink radio link can be reliably received corresponding to 2% BLER of a hypothetical PDCCH transmission taking into account the PCFICH errors. The in-sync and out-of-sync are evaluated during time window which depends on the DRX settings as shown in [6]. In case of no DRX: if the downlink radio link quality of the Pcell estimated over the last 200 ms is worse than Qout, the physical layer sends out-of- sync indication to layer 3. In case out-of-sync is detected the UE initiates evaluation of in-sync. The UE layer 3 evaluates radio link failure based on the out-of-sync and in-sync indications after layer 3 filtering (layer 3 filtering as specified in [4]). As shown in Figure 12.26, upon receiving N310 consecutive out-of-sync indications for the Pcell from physical layers while none of the timers T300, T301, T304 or T311 is running the UE starts the timer T310. In case while T310 is running there are N311 in-sync indications from physical layer the radio link is considered to be recovered and normal operation continues. The time between two successive radio link status indications from physical layer is defined in [6] to be minimum 10 ms. In case the UE layer 3 does not receive N311 consecutive in-sync indications while T310 is running and T310 expires, the UE initiates re-establishment procedure as shown in Fig- ure 12.27. If the UE can find a suitable cell and successfully send the RRC connection re
