s even bigger since the UE cannot be scheduled immediately before the gap in downlink and the UE cannot transmit immediately after the gap in uplink. Furthermore, transmission control protocol (TCP) throughput could suffer even more since delay peaks increase the burstiness of the TCP flow, possibly resulting in increased TCP retransmissions. Most of the connected mode measurement events have their natural idle mode counter-part. For example, the idle mode 'dual' of the A1 event is the sIntraSearch when used for intra- frequency measurement activation/deactivation. In a similar fashion, the A3 event corresponds to cell reselection between equal priority layers with hysteresis, and A4 event is the connected LTE Small Cell Optimization Table 15.8 Summary of events that can trigger a measurement report [4] Event Event trigger Example use case Ms > alThreshold With Ms = RSRP, triggering measurement gaps for handover from coverage layer (e.g. LTE800) to capacity layer (e.g. LTE2600). Deactivating serving layer measurements, i.e., connected mode counter-part to sIntraSearch Ms < a2Threshold Triggering measurement gaps, i.e. connected mode counter-part to sNonIntraSearch Ms < Mn + a3Offset With Ms = RSRP, basic power budget handover to keep connected to the cell with least path loss, i.e. connected mode counter-part to idle mode reselection to a equal priority layer where A3 offset is equal to reselection hysteresis Mn > a4Threshold With Ms = RSRP, moving to a higher priority layer if the level is good enough, i.e. connected mode counter-part to reselection to a higher priority layer Ms a5Threshold1 With Ms = RSRP, moving to a lower priority layer if Mn > a5Threshold2 the serving layer level is below acceptable and the target cell level is acceptable, i.e. connected mode counter-part to reselection to a lower priority layer B1 (inter-RAT) Mn > b1Threshold With Mn = Ec/NO, CSFB PS handover where Ec/NO threshold is set to a value where call quality and call setup success rate can be expected to be acceptable.
