Abstract: Example embodiments of the present disclosure relate to methods, devices, apparatuses and computer readable storage medium for Random Access Channel (RACH) occasion (RO) dropping. In a method, a device determines a set of valid random access channel occasions (ROs) for a physical random access channel (PRACH) transmission with preamble repetitions. The device determines that the PRACH transmission is to be dropped in at least one RO of the set of valid ROs. The device determines one or more ROs of the set of valid ROs for calculation of a random access radio network temporary identifier (RA-RNTI), the one or more ROs for calculation of the RA-RNTI are not conditioned to whether the corresponding PRACH transmission over the one or more ROs is to be dropped. Then the device calculates the RA-RNTI based on the determined one or more ROs of the set of valid ROs.

Abstract: A method including receiving, from a network device, configuration information for random access, wherein the configuration information comprises parameters for determining a plurality of random access channel occasions and for mapping the plurality of random access channel occasions with one or more of a plurality of synchronization signal block indices; indexing the plurality of random access channel occasions; grouping the plurality of random access channel occasions into one or more random access channel occasion groups based on the indexing; and transmitting, to the network device, a plurality of physical random access channel transmissions using at least one of the one or more random access channel occasion groups.
