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.

Abstract: A method and apparatus for a user equipment (UE) performing a random access procedure are disclosed. For this end, the UE receives configuration information from the network. Here, the configuration information indicates: one or more prioritized events, and numbers (>1) of random access preambles respectively assigned for each of the prioritized events. The UE transmits a single random access preamble to the network, if the random access procedure is triggered by a first event other than the prioritized events. And, the UE transmits multiple random access preambles to the network, if the random access procedure is triggered by a second event belonging to the prioritized events. Here, the number of the multiple random access preambles corresponds to the number of random access preamble assigned for the second event in the configuration information.

Abstract: A method and apparatus for a user equipment (UE) to transmit data to a network is disclosed. The UE sets a poll bit in a PDCP (Packet Data Convergence Protocol) PDU (Protocol Data Unit) to a first value to request a status report including a second FMN (First Missing Number) from the network, if a predetermined number of PDCP SDUs (Service Data Units) are transmitted after a PDCP SDU corresponding to a first FMN.

Abstract: A method and apparatus for configuring radio bearers in a wireless communication system is provided. A user equipment (UE) receives a configuration from a evolved NodeB (eNB) controlling a first cell, configures a first type of radio bearers for the first cell only, and configures a second type of radio bearers for both the first cell and a second cell. The first cell is a cell using resources on a licensed carrier. The second cell is a cell using resources on an unlicensed carrier.
