y. For example, if the maximum UE transmit power in the cell is broadcast as 33 dBm and the UE maximum power capability is 23 dBm, the UE would apply a 10 dB penalty term and the cell radius would effectively shrink by 10 dB for this UE. Improper selection of UE maximum transmit power can result ping-pong cell reselection; the simplest solution is to omit the parameter on BCCH in which case the UE automatically sets the power compensation term to 0 dB. As will be discussed next, 3GPP Release 8 and beyond specify absolute priority-based cell reselection. However, before proceeding it is worth remarking that absolute priorities provided to the UE in BCCH system information or in radio resource control (RRC) release message are not used in the initial cell selection process. LTE Small Cell Optimization 15.2.2 Summary of Cell Reselection Rules Cell Reselection to Equal Priority Layer Reselection to cells with the same priority as the serving cell is based on best RSRP; however, the candidate target cell must be better by an offset which is the sum of hysteresis, target cell-specific offset and target frequency-specific offset. Only the cell reselection hysteresis is mandatorily broadcast, while the latter two parameters have a default value of 0 dB if not broadcast. Quality-based reselection to an equal priority layer or cell is not supported. Cell Reselection to Higher Priority Layer From 3GPP Release 8 and onwards idle mobility towards non-equal priority layer is based on the concept of absolute priorities. The difference to pre-Release 8 mobility is that reselection to a cell with higher priority is not based on choosing the cell with the best signal level. Instead the UE reselects to the cell with the highest priority as long as the pilot signal level or quality from the candidate is above a threshold broadcast in the serving cell. In 3GPP Release 9 inter-frequency cell reselection based on quality criterion (RSRQ) was added. Therefore, in plain text the 3GPP Release 9 reselection criterion towards a higher prior
