Abstract: An apparatus may be configured to: receive information comprising at least: an indication of a first PRACH configuration, wherein the first PRACH configuration is associated with an identifier of at least one first radio beam, and an indication of a second PRACH configuration, at least partially different from the first PRACH configuration, wherein the second PRACH configuration is associated with an identifier of at least one second radio beam, wherein the at least one second radio beam comprises, at least, a radio beam for communicating with a network node via a repeater; select a radio beam; select a PRACH configuration based, at least partially, on the received information; and transmit, to the network node, a radio access preamble on the selected radio beam according to the selected PRACH configuration.

Abstract: Systems, methods, apparatuses, and computer program products for facilitating explicit latency mode determination in beam switching. One method may include receiving, by a user equipment, at least one beam switch command from at least one network entity. The user equipment may further determine at least one latency and switching mode, and perform beam switch based on the at least one latency and switching mode.
