APPARATUSES AND METHODS FOR PREAMBLE SEQUENCE MANAGEMENT FOR CONTENTION BASED ACCESS

Abstract(summary):

Systems, methods, apparatuses, and computer program products of preamble sequence management for contention based access are provided. One method may include a user equipment sending a contention based access (CBA) request message, such as a random access procedure (RACH) message, to a network node (e.g., a base station or eNB). The CBA request message may include an indication that the user equipment wants to obtain a preamble for CBA data transmission and is not for full network access. The method may then include receiving an allocation of a preamble for CBA from the network node.
