Title: CLASSIFICATION OF USER EQUIPMENT USING EXTENDED SET OF RANDOM ACCESS PREAMBLES
Abstract:
A random access process may be performed with an extended set of random access preambles comprising a standard set and at least one additional set. The use of a preamble from the standard set or the additional set may be used to indicate whether a wireless communication device belongs to a standard class or a non-standard class, allowing a radio access node to provide special treatment to the non-standard class in a random access response.
