Abstract  Abstract

A method and terminal for use in a communication system are discussed. The terminal can transmit a random access preamble via a physical random access channel (PRACH) to a network. The terminal may monitor a random access response after transmitting the random access preamble during a specific time window. Furthermore if no random access response containing a random access preamble identifier corresponding to the transmitted random access preamble is received within the specific time window and a specific random access response contains a backoff indicator subheader is received a preamble transmission counter is incremented by 1. A subsequent random access preamble transmission is delayed by a backoff time selected using a backoff indicator in the backoff indicator subheader if the random access preamble was selected by a medium access control (MAC) layer.
