PHYSICAL RANDOM ACCESS CHANNEL AND RANDOM ACCESS RESPONSE DETECTION FOR USER EQUIPMENT

摘要

Systems, methods, apparatuses, and computer program products of physical random access channel (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.
