Random access procedure with enhanced coverage

(57)    Abstract

A random access procedure for use by a UE wireless communication terminal in communicating with a base station (or Node-B or eNB) of a radio access network, and in particular a E-UTRA network. A random access preamble is sent by the UE via RACH separate and prior to a random access message burst, which is sent on SCH but not until the UE receives one or more messages indicating an acknowledgment of the preamble and providing an allocation on SCH for use in transmitting the message burst, and also providing a preamble identifier, which the radio access network can then use to request retransmission of the message burst if necessary.
