receiving the signaling information from the base station in response to the service request.

5. The method as claimed in claim 4 , wherein the service request is sent by a RF transceiver and the signaling information is received by one of (a) the RF transceiver and (b) a further RF transceiver.

6. The method as claimed in claim 1 , wherein the signaling information and corresponding characteristics of the signaling information is based on channel quality indicator, repetition factor, retransmission request, aggregation level, and signal strength of the UE, wherein the characteristics of the signaling information include periodicity, transmission, and format.
