e UE does not hear the random access response message or the corresponding DCI) and therefore the random access response transmission parameters for PDCCH and PDSCH must be properly set. For PDCCH this means that the coding rate (as CCE aggregation level) for the used DCI must be selected according to the coverage conditions of the cell. The DCI for random access response is transmitted in common search space which means that it can only have aggregation level 4 or 8. The aggregation level can be either fixed by parameters or allocated automatically by eNodeB algorithms depending on the coverage conditions. For PDSCH the coding rate for actual random access message delivery needs to be set SO that it corresponds to the selected DCI PDCCH aggregation level; otherwise, the UE might be able to hear the DCI from PDCCH but not the actual random access response message on PDSCH causing unnecessary repetitions of random access procedures. Message 3, the Radio Resource Control Connection Request Message, Transmission Once the UE has successfully received the random access response, it will send RRC con- nection request message (message 3) to the eNodeB on PUSCH with the power according to Eq. 12.2 (assuming PUSCH transmission and no simultaneous PUSCH and PUCCH transmission) using the resources indicated in the random access response message: PCMAX, PPUSCHMsg3 min 10log(MPUSCH(i)) + preambleInitialReceivedTargetPower + (12.2) APREAMBLE_Msg3 + a(j) PL + ATF(i) + ^Prampup + Msg2 where PCMAX is the configured UE transmit power defined in [2] in subframe i for serving cell c; i is the subframe number; MPUSCH(i) is the number of physical resource blocks (PRBs) for PUSCH transmission; LTE Small Cell Optimization preambleInitialReceivedTargetPower is the target power for preamble reception at the eNodeB as shown in Eq. 12.1; APREAMBLE_Msg3 = DeltaPreambleMsg3 given in system information block type 2; ATF(i) is the MCS-dependent component as defined in [1]; PL is the downlink path-loss estimate calculated in the UE for serving c
