Abstract: A method of performing a random access channel (RACH) procedure between a mobile terminal and a network includes the steps of detecting whether a random access response (RAR) is received from the network within a certain time period, the RAR including information about a random access channel (RACH) preamble transmitted to the network; and if the RAR is not received within the certain time period or if the information about the transmitted RACH preamble included in the RAR does not match the transmitted RACH preamble, performing a first procedure to detect failures in the RACH procedure; and if the RAR is received within the certain time period and if the information about the transmitted RACH preamble included in the RAR matches the transmitted RACH preamble, performing a second procedure to detect failures in the RACH procedure.

Abstract: A random access procedure between a mobile terminal and a network is performed based upon the characteristics of a RACH preamble. If the RACH preamble was explicitly signaled by the network, a downlink channel is monitored until a new transmission is indicated according to radio resource allocation information received from the network. If the RACH preamble was not explicitly signaled by the network, a contention resolution timer is started and the downlink channel is monitored until the contention resolution timer expires. Such monitoring of downlink channels in a more efficient manner, results in effective reduction in power consumption.

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.

When the validity timer is expired, the user equipment discards the MDT configuration and starts a conservation timer. When the conservation timer is expired, the logged measurements are discarded.
