Abstract
A method and apparatus for accessing a NR cell in a mobile communication system are provided. Method for accessing a NR cell includes receiving in a first cell, by a terminal from a base station, a Master Information Block (MIB) and a System Information Block1 (SIB1), determining, by the terminal, if the first cell is barred and performing by the terminal a first operation group if the cell is barred and perform, if the first cell is not barred, a second operation group.
Claims10
A method by a base station, the method comprising:
- transmitting by the base station a system information, wherein the system information comprises a set of random access parameters, wherein the set of random access parameters comprises at least a first set of preamble parameters;
- and
- performing by the base station reception of a preamble based on:
- a parameter related to preamble subcarrier spacing;
- and
- a parameter related to preamble selection threshold,
- wherein performing reception of the preamble comprises:
- applying the parameter related to preamble subcarrier spacing in the first set of preamble parameters and the parameter related to preamble selection threshold in a second set of preamble parameters to transmission of the preamble in case that the set of random access parameters comprises the second set of preamble parameters;
- and
- applying the parameter related to preamble subcarrier spacing in the first set of preamble parameters and the parameter related to preamble selection threshold in the first set of preamble parameters to transmission of the preamble in case that the set of random access parameters does not comprise the second set of preamble parameters.
