Claim:
1. A Long Term Evolution (LTE) wireless communication system comprising: a) a Limited Capability Terminal Equipment (LCTE) configured, upon initiating a physical random access channel (PRACH) random access operation, to select a PRACH preamble from a predetermined subset of PRACH preambles, said subset of PRACH preambles being strictly contained within and strictly smaller in size than a set of Group A or Group B contention-based PRACH preambles defined for the LTE system, the selected PRACH preamble included in wireless transmission of a PRACH preamble message; and b) an evolved Node B (eNB) configured, in response to receipt of the PRACH preamble belonging to said subset of PRACH preambles, to schedule transmission of an associated random access response (RAR) on a restricted set of physical resource blocks (PRBs) which is predictable and accessible to said LCTE.
