Abstract
A method by a user equipment (UE) is described. The method includes receiving, from a base station, system information including physical random access channel (PRACH) configuration information, wherein the PRACH configuration information includes a list of preamble index ranges, where each preamble index range is associated with a synchronization signal block (SSB), wherein each preamble index range comprises one or a plurality of sub-ranges; and selecting, based on one or a plurality of reference signal received power (RSRP) values of a set of SSBs and a first RSRP threshold configured by a radio resource control (RRC) layer, an SSB from the set of SSBs; and selecting, based on the RSRP value associated with the selected SSB and one or more second RSRP thresholds configured by the RRC layer, a subrange from the one or a plurality of sub-ranges associated with the selected SSB; and selecting a preamble index from the selected sub-range. The first RSRP threshold and the second RSRP threshold(s) are configured by two separate RRC parameters, or configured by one RRC parameter.
