Initial PRACH (The first PRACH that UE transmit) is determined by the following formula. Initial RACH Preamble Power = Primary CPICH TX Power – CPICH_RSCP + UL_Interference + Constant Value. CPICH_RSCP is the power directly measured by UE and all other parameters are calculated (obtained) from system information. WebA method for receiving a preamble of a physical random access channel (PRACH) may comprise: obtaining information and parameter(s) for receiving a first PRACH preamble from one antenna in an n-th slot, n being an arbitrary natural number; generating a first parameter set including first stage parameters and second stage parameters for … food wars : shokugeki no soma season 5
