Abstract
Methods and apparatuses for radio frequency exposure mitigation via beam selection for random access procedure. A method for performing a random access (RA) procedure includes receiving information for a set of downlink reference signals (DL RSs). The method further includes determining: a set of DL reference signal received powers (RSRPs) corresponding to the set of DL RSs, a set of spatial filters corresponding to the set of DL RSs, a set of exposure levels corresponding to the set of spatial filters, a first DL RS from the set of DL RSs based on the set of DL RSRPs and the set of exposure levels, and a first spatial filter corresponding to the first DL RS. The method further includes transmitting a physical random access channel (PRACH), a physical uplink shared channel (PUSCH), or a physical uplink control channel (PUCCH) using the first spatial filter.
