Method of accessing a physical random access channel, method of signaling access information for accessing a physical random access channel, mobile communication terminal and base station

A mobile communication terminal, comprising:

• a control unit to select a plurality of transmission occasions from transmission occasions being allowed transmitting a random access preamble in a predefined transmission frequency region which is different from a previous predefined transmission frequency region, if a previous random access preamble transmission based on the previous predefined transmission frequency region was not acknowledged by a base station and further to randomly select one transmission occasion of the plurality of transmission occasions for transmitting the random access preamble;
• and
• a transmit unit to transmit the random access preamble in the randomly selected transmission occasion;
• wherein the control unit is to include less transmission occasions in the plurality of transmission occasions in case of a higher priority of transmitting the random access preamble and include more transmission occasions in the plurality of transmission occasions in case of a lower priority of transmitting the random access preamble.

Method of signaling access information for accessing a physical random access channel, comprising:

• broadcasting parameter information for determining transmission occasions being allowed for transmitting a random access preamble in a predefined transmission frequency region which is different from a previous predefined transmission frequency region, if a previous access preamble transmission based on the previous predefined transmission frequency region was not acknowledged by a base station;
• and
• broadcasting a piece of information indicating how to select a plurality of occasions from the transmission occasions being allowed for transmitting the random access preamble, the piece of information further indicating that the random access preamble may only be transmitted in one randomly selected transmission occasion of the plurality of transmission occasions;
• wherein the selecting of the plurality of transmission occasions includes selecting less transmission occasions in case of a higher priority of transmitting the random access preamble and includes selecting more transmission occasions in case of a lower priority of transmitting the random access preamble.
