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: The present invention relates to a method for performing uplink transmissions by a user equipment in a wireless communication system. In particular, the method includes the steps of: transmitting a data unit to a network using a configured uplink grant; receiving an uplink grant for retransmission of the data unit from the network; determining a retransmission timing using a parameter related to a retransmission delay; and retransmitting the data unit to the network using the uplink grant for retransmission on the determined retransmission timing. Especially, the configured uplink grant is shared by the user equipment and another user equipment, and the parameter indicates at least one instance of retransmission delay.

Abstract: The present invention relates to a method for receiving packets by a decompressor in a wireless communication system. In particular, the method includes receiving a full header packet from a compressor, wherein the full header packet includes a context identifier (CID) and a header context; establishing the header context; transmitting a feedback packet including the CID; starting a timer related to the CID; and based on not receiving a compressed header packet related to the CID until expiration of the timer, retransmitting the feedback packet including the CID to the compressor.

Abstract: A method for processing downlink (DL) signals by a user equipment (UE) in a wireless communication system is disclosed. Especially, the UE is configured not to transmit a Hybrid Automatic Repeat and request (HARQ) feedback for the DL HARQ process. The method comprises steps of upon a first Physical downlink Control Channel (PDCCH) for the DL HARQ process is detected, starting a timer for monitoring subsequent PDCCHs related to retransmission of the DL HARQ process, without transmitting the HARQ feedback; and monitoring subsequent PDCCHs related to retransmission of the DL HARQ process while the timer is running.

Abstract: In the present invention, service data units (SDUs) are delivered from a first layer to a second layer out-of-order irrespective of sequence numbers (SNs) of the SDUs. The second layer deciphers the SDUs in the order of reception from the first layer irrespective of the SNs. The second layer may reorders the deciphered SDUs in the order of the SNs, and delivers them to an upper layer in sequence.
