Abstract: A method and apparatus for a user equipment (UE) performing random access to a network is disclosed. For this end, the UE determines a predetermined number of beams, as candidate beams for the random access to the network, among multiple beams, wherein each of the multiple beams is allocated on different time domain units. And, the UE transmits the random access preamble over a transmission beam selected as one from the candidate beams to the network.
