1. A terminal, comprising:
- a generator to generate a request for radio network resources from a cellular network;
a transmitter to transmit the request for radio network resources to a relay device at a time in which both the terminal and the relay device are located within a cell served by a base station,wherein the request for radio network resources includes a request for a dedicated random access channel (RACH) preamble and is to be forwarded by the relay device to the base station of the cellular network; and
a controller to;
receive a RACH assignment, which includes a dedicated RACH preamble, based on the request; and
perform a non-contention based random access procedure with the base station by sending the dedicated RACH preamble directly to the base station to establish a cellular network connection between the terminal and the base station of the cellular network using radio network resources assigned to the terminal by the cellular network.

Abstract
A terminal may include a generator configured to generate a request for radio network resources from a cellular network; a transmitter configured to transmit the request for radio network resources to a relay device, wherein the request for radio network resources may be configured to be forwarded by the relay device to a base station of the cellular network; and a controller configured to establish a cellular network connection between the terminal and the base station of the cellular network using radio network resources assigned to the terminal by the cellular network.

19. A base station, comprising:
-
a receiver to receive, from a relay device, a request by a terminal for radio network resources from a cellular network, wherein the request is a random access channel resource (RACH) request for a dedicated random access channel (RACH) preamble and is received at a time in which both the terminal and the relay device are located within a cell served by the base station; an allocation circuit to perform a RACH assignment to the terminal based on the request for a dedicated RACH preamble, the RACH assignment to include a dedicated RACH preamble for the terminal; and a transmitter to transmit information about the RACH assignment to the terminal or the relay device, wherein the receiver is further to receive the dedicated RACH preamble directly from the terminal as part of a non-contention random access procedure. - View Dependent Claims (20)

21. A method for establishing a cellular network connection between a terminal and a base station, comprising:
-
generating a request for radio network resources from a cellular network, the request being a random access channel (RACH) request for a dedicated RACH preamble; transmitting the request for radio network resources to a relay device at a time in which both the terminal and the relay device are located in a cell served by the base station, wherein the request for radio network resources is configured to be forwarded by the relay device to the base station of the cellular network; receive a RACH assignment, which includes a dedicated RACH preamble, based on the request; and perform a non-contention random access procedure by sending the dedicated RACH preamble directly to the base station to establish a cellular network connection between the terminal and the base station of the cellular network using radio network resources assigned to the terminal by the cellular network.
