    Abstract: Method and apparatus for a user equipment (UE) performing random access are disclosed. For this end, the UE transmits first multiple random access preambles for a random access procedure to the network, and monitors random access responses respectively corresponding to each of the first multiple random access preambles during each of multiple random access response reception windows. The UE transmits second multiple random access preambles for the random access procedure to the network, if a random access response reception of the first multiple random access preambles is determined as not successful. Here, the random access response reception is determined as not successful, when none of the random access responses is successfully received until a last random access response reception window among the multiple random access response reception windows ends.

    Abstract: The present invention relates to a wireless communication system. More specifically, the present invention relates to a method and a device for triggering a buffer status reporting in wireless communication system, the method comprising: configuring with a first SR resource configuration and a second SR resource configuration; checking whether or not data is a first data on logical channels mapped to the first SR resource configuration, when the data becomes available for a first logical channel mapped to the first SR resource configuration, in a state that the first logical channel has a lower priority than a highest priority among priorities of logical channels having data, which are mapped to the second SR resource configuration; and triggering a first BSR if the data is the first data on logical channels mapped to the first SR resource configuration.

    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: A user equipment (UE) receives first configuration information for one or more numerology sets, each numerology set including one or more numerologies. The UE receives second configuration information for one or more logical channels, each logical channel mapped to one or more numerologies. The UE receives a first uplink (UL) grant for new transmission, the first UL grant including information indicating a numerology set associated with the first UL grant. The UE generates a MAC PDU. The UE performs a new transmission of the MAC PDU using the first UL grant. The MAC PDU contains data from a logical channel of which every numerology belongs to the numerology set.
