Abstract

A method for a wireless communications network for data packet including a user equipment (UE) and a transceiver node (eNodeB). The user equipment (UE) and the node (eNodeB) intercommunicate over an air interface communication link. The user equipment (UE) transmits a first message (MSG3) in a first scheduled transmission in a random access procedure during setup of the communication link. The first message is transmitted in a first sub frame (TTI=3) and in a second sub frame (TTI=4; TTI=5) within a first roundtrip time (RTT) in a first HARQ- process triggered by the transmission of the first message in the first sub frame (TTI=3).
