Abstract
Disclosed are methods and apparatus for determining time-domain PRACH resources in wireless communication. A New Radio (NR) Physical Random Access Channel (PRACH) configuration comprising an indication of a time-domain PRACH resource type to determine when the UE is allowed to transmit a PRACH preamble and a type of preamble format may be received. Additionally, a PRACH resource based on the received PRACH configuration to transmit the PRACH preamble, wherein the PRACH resource includes RACH resource occasions (ROs) with gaps in between may be determined. Thereafter, a PRACH procedure may be initiated by transmitting the PRACH preamble on a RO based on the determined PRACH resource to a base station (BS).
