o the previous value of g(i) according to g(i) = g(i - i-km), where for FD mode M = 1 and ko = 4 and for TD as defined in [1]. The power control settings for PUSCH and PUCCH must follow the same strategy, that is, in case PUSCH power control is aggressive then PUCCH power control should also be aggressive. Similarly in case PUSCH power control is conservative then PUCCH power control should also be conservative. This way the UE transmission power has less fluctuation between PUSCH and PUCCH and therefore power differences per allocated physical resource block are smaller and signalling on PUCCH is improved (CQI and ACK/NACK). UE transmission power control for PUCCH is further analysed in Section 12.5. At the point of message 5 transmission the closed-loop power control does not cause any increase or decrease of the UE transmission power as there are no received signal strength indicator and signal to noise and interference measurement results available from previous PUSCH dynamic scheduling allocations. Therefore, message 5 power is set by open-loop power control part (alpha, PO_NOMINAL_PUSCH (j) + PO_UE_PUSCH(i), path loss measured by the UE and in case of cumulative closed-loop power control, message 3 closed-loop part explained in Section 12.4.1). Similarly for scheduling request transmission the UE transmission power is determined by the open-loop power control part (PO_NOMINAL_PUCCH + PO_UE_PUCCH) as there are not many PUCCH transmissions based on which the closed-loop part could be adjusted. The open-loop parameter values for PUSCH and PUCCH are network specific due to the different coverage and interference (inter-cell and load based) conditions and should be adjusted together with resource allocation optimization. The PDCCH CCE aggregation level (i.e. coding rate) for DCI is determined by the received CQI reports (parameters given in RRC LTE Small Cell Optimization connection setup message) and therefore based on link adaptation or in case of no CQI reports received the aggregation level is decided based
