Abstract: The present invention relates to a method for performing uplink transmissions by a transmission end in a wireless communication system. In particular, the method includes the steps of: receiving a dynamic uplink grant for a HARQ process from a reception end; and performing an uplink transmission scheduled by the dynamic uplink grant, wherein at least one uplink transmission on at least one configured uplink grant for the HARQ process after receiving the dynamic uplink grant before performing the uplink transmission scheduled by the dynamic uplink grant is skipped.

Abstract: The present invention relates to a communication between MAC layer entity and PHY layer entity for parallel random access procedures of dual connectivity. In this scheme, a first PHY entity of a user equipment informs a failure of a random access preamble transmission to a first MAC entity of the UE. Then, the first MAC entity continues or stops a random access procedure without performing procedures for a random access failure.

Abstract: A method for transmitting signals by a medium access control (MAC) entity of a transmission end in a wireless communication system is disclosed. The method comprises initializing a random access procedure on a secondary cell for beam failure recovery (BFR); transmitting an indication for requesting at least one suitable beam to a lower layer; if information about the at least one suitable beam is not received from the lower layer, incrementing a random access preamble transmission counter; and when the random access preamble transmission counter is less than a maximum value, retransmitting the indication for requesting the at least one suitable beam to the lower layer.

Abstract: The present invention relates to a wireless communication system. More specifically, the present invention relates to a method and a device for processing an uplink grant of which a resource size is zero in wireless communication system, the method comprising: transmitting uplink data; receiving uplink grant after the uplink data is transmitted; considering that the uplink data transmission is performed successfully, if a resource size of the uplink grant is ‘zero’; and performing a Hybrid-ARQ (HARQ) process of the uplink data as successful uplink transmission.

Abstract: A method and apparatus for configuring a prohibit timer for a sidelink transmission in a wireless communication system is provided. A user equipment (UE) configures a prohibit timer for the sidelink transmission for a specific channel, starts the prohibit timer when a number of data units transmitted via the specific channel reaches to a specific number, and prohibits the sidelink transmission while the prohibit timer is running.

Abstract: A user equipment (UE) determines whether a size of data available for transmission in a PDCP (Packet Data Convergence Protocol) entity of the UE, excluding a size of a PDCP Control PDU (Protocol Data Unit), exceeds a threshold value. Here, the PDCP Control PDU is predetermined to be transmitted through the first link of the bearer. The PDCP entity of the UE informs an indication on (a) the size of the data available for transmission, or (b) the size of the PDCP Control PDU, to a first entity of the UE for the first link based on the determination, and the first entity can transmit a buffer status report to the network based on the indication. Here, the size of the data available for transmission in the PDCP includes the size of the PDCP Data PDU and the size of the PDCP Control PDU.
