Abstract: The load on Random Access channels (N)PRACH (i.e., Msg1) is temporally distributed, to better handle synchronized access peaks from machine type devices. Access attempts by wireless devices are distributed in time, based on their identities (e.g., IMSI, which is used for the distribution of paging load) or random draw. The distribution restricts when 5 wireless devices can access the network, either based on System Frame Number or on random access occurrence. The method is implicit, i.e., after the initial System Information (SI) acquisition, wireless devices will automatically apply temporal network access load distribution according to the configuration provided in SI without any need for explicit signaling or re-acquisition of SI. Embodiments of the invention may be advantageously applied to any wireless 10 communication network supporting machine type communications, such as GPRS/EGPRS/ECGSM-IoT and UMTS/HSPA, as well as non-3GPP radio access technologies such as LoRa, Sigfox, and Ingenu.

Abstract: Systems and methods are disclosed for performing random access (RA) in 5G New Radio (NR) systems, including New Radio in unlicensed spectrum (NR-U) systems. A wireless transmit/receive unit (WTRU) may receive a configuration for physical random access channel (PRACH) resources.

For the first type of PRACH transmission, the WTRU may select a PRACH resource, without performing listen-before-talk (LBT), immediately following reception of an synchronization signal block (SSB). For the second type of PRACH transmission, the WTRU may randomly select the PRACH resource associated with the SSB, and perform a first LBT on the selected PRACH resource. The WTRU may transmit a PRACH preamble in the selected PRACH resource. The WTRU may perform a second LBT for random access response (RAR) reception for hidden node detection.
