Summary:Methods and apparatus for random access procedures with spatial settings. A method of operating a user equipment includes receiving a system information block (SIB). The SIB indicates a set of channel state information reference signals (CSI-RS) resources for CSI-RSs, a set of random access occasions (ROs), and a mapping between the set of ROs and the set of CSI-RS resources. The method further includes determining a first RO from the set of ROs for transmission of a first physical random access channel (PRACH), determining a first spatial setting for the first PRACH transmission based on a first CSI-RS resource from the set of CSI-RS resources that is mapped to the first RO, and transmitting the first PRACH in the first RO using the first spatial setting.
