Kind Code:
A1
Abstract:
The disclosure relates to a 5G or 6G communication system for supporting a higher data transmission rate. A method and apparatus for initial access with multiple physical random access channel (PRACH) transmissions in a wireless communication system is provided. A method includes receiving a system information block (SIB) that indicates a first number of multiple PRACH transmissions, a first partition of PRACH occasions (ROs) associated with multiple PRACH transmissions, a second partition of ROs associated with one PRACH transmission, and one or more first sets of multiple ROs associated with the first number of multiple PRACH transmissions. The one or more first sets include ROs from the first partition of ROs but not from the second partition of ROs The method further includes determining a group of ROs from the one or more first sets of multiple ROs, determining a PRACH preamble for transmission in a first number of ROs of the group of ROs, and transmitting the PRACH preamble in the first number of ROs of the group of ROs.
