Abstract: The present disclosure relates to a method for transmitting signals by a transmission end in a wireless communication system. In particular, the method includes configuring first and second type logical channel groups; receiving a first uplink grant; and transmitting buffer size information based on the uplink grant, wherein, when the first uplink grant is allowed to be used for transmission of buffer size information of the second logical channel group, the buffer size information includes the buffer size information of the first and second logical channel groups, and wherein, when the first uplink grant is not allowed to be used for transmission of buffer size information of the second logical channel group, the buffer size information includes the buffer size information of the first logical channel group.

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: A method and apparatus for performing an uplink (UL) transmission with pre-allocated beams in a wireless communication system is provided. A user equipment (UE) receives a connection release message from a network in a first state. The connection release message includes information on a pre-allocated UL resource for UL transmission with pre-allocated beams. The UE enters a second sate from the first state, selects a cell, and performs the UL transmission to the cell in the second state via the pre-allocated beams based on the pre-configured UL resource for UL transmission when a data is available for transmission. The first state may be a radio resource control (RRC) connected state, and the second state may be an RRC inactive state and/or an RRC idle state.
