Section: 5.5.4.9 Event B2 (PCell becomes worse than threshold1 and inter RAT neighbour becomes better than threshold2)
Content: The UE shall: 1> consider the entering condition for this event to be satisfied when both condition B2-1 and condition B2-2, as specified below, are fulfilled; 1> consider the leaving condition for this event to be satisfied when condition B2-3 or condition B2-4, i.e. at least one of the two, as specified below, is fulfilled; Inequality B2-1 (Entering condition 1) Mp + Hys < Thresh1 Inequality B2-2 (Entering condition 2) Mn + Ofn + Ocn – Hys > Thresh2 Inequality B2-3 (Leaving condition 1) Mp – Hys > Thresh1 Inequality B2-4 (Leaving condition 2) Mn + Ofn + Ocn + Hys < Thresh2 The variables in the formula are defined as follows: Mp is the measurement result of the PCell, not taking into account any offsets. Mn is the measurement result of the inter-RAT neighbour cell, not taking into account any offsets. Ofn is the measurement object specific offset of the frequency of the inter-RAT neighbour cell (i.e. eutra-Q-OffsetRange as defined within the measObjectEUTRA corresponding to the frequency of the inter-RAT neighbour cell, utra-FDD-Q-OffsetRange as defined within the measObjectUTRA-FDD corresponding to the frequency of the neighbour inter-RAT cell). Ocn is the cell specific offset of the inter-RAT neighbour cell (i.e. cellIndividualOffset as defined within the measObjectEUTRA corresponding to the neighbour inter-RAT cell, or cellIndividualOffset as defined within reportConfigInterRAT), and set to zero if not configured for the neighbour cell. Hys is the hysteresis parameter for this event (i.e. hysteresis as defined within reportConfigInterRAT for this event). Thresh1 is the threshold parameter for this event (i.e. b2-Threshold1 as defined within reportConfigInterRAT for this event). Thresh2 is the threshold parameter for this event (i.e. b2-Threshold2EUTRA as defined within reportConfigInterRAT for this event, b2-Threshold2UTRA-FDD as defined for UTRA-FDD within reportConfigInterRAT for this event). Mp is expressed in dBm in case of RSRP, or in dB in case of RSRQ and SINR. Mn is expressed in dBm or dB, depending on the measurement quantity of the inter-RAT neighbour cell. Ofn, Ocn, Hys are expressed in dB. Thresh1 is expressed in the same unit as Mp. Thresh2 is expressed in the same unit as Mn.
