摘要：
Systems, methods, apparatuses, and computer program products of PRACH selection and random access response (RAR) detection are provided. One method includes specifying, by a network node, a starting point for preamble repetition having a repetition level such that all user equipment (UEs) of the same repetition level start the preamble repetition on a same physical random access channel (PRACH) resource, determining when a series of the preamble repetition is over, and transmitting a random access response (RAR) when the repetition series is finished.
