Abstract: A method and apparatus for selecting a NR cell in a mobile communication system are provided. Method for selecting a NR cell includes selecting, by a terminal, a first cell, acquiring, by the terminal in the first cell, a MIB, acquiring, by the terminal in the first cell, a SIB1 based at least in part on a first information in the MIB, considering, by the terminal, the first cell as barred, performing, by the terminal a first operation group if the SIB1 received in the first cell does not include a intraFreqReselection and performing, by the terminal a second operation group if the SIB1 received in the first cell includes the intraFreqReselection and the second intraFreqReselection is set to NotAllowed.

Abstract: A base station may transmit a system information block 1 (SIB1) message of a cell. The SIB1 message may indicate a plurality of configuration parameters comprising a common uplink configuration of an uplink bandwidth part (BWP). The common uplink configuration of the uplink BWP may comprise: a common random access channel (RACH) configuration, a threshold for determining whether to select a resource associated with a physical random access channel (PRACH) preamble repetition number, and a second RACH configuration associated with feature combination. The second RACH configuration may indicate the PRACH preamble repetition number. A wireless device may determine, based on the threshold and based on the PRACH preamble repetition number, a repetition number for PRACH preamble transmission, and repeatedly transmit, based on the determined repetition number, a PRACH preamble of a random access procedure associated with the second RACH configuration.
