Abstract: A method for performing beam failure recovery (BFR) in a user equipment in a wireless communication system is disclosed. The method comprises performing a contention free random access procedure for BFR using a first beam during a BFR timer is running; and if the contention free random access procedure does not succeed until the BFR timer expires, performing a contention based random access procedure for BFR using a second beam selected from a beam set, wherein the first beam is excluded from the beam set.

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 dual connectivity, the method comprising: configuring a threshold value for a PDCPentity associated with a first MAC entity for a first eNB and a second MAC entity for a second eNB for a radio bearer; checking, by the PDCP entity, whether an amount of uplink data available for transmission in the PDCP entity is less than the threshold value; and indicating, by the PDCP entity, that the amount of uplink data available for transmission in the PDCP entity is ‘0’ to the second MAC entity, if the amount of uplink data available for transmission in the PDCP entity is less than the threshold value.

Abstract: Method and apparatus for a user equipment (UE) transmitting uplink signals in a wireless communication system are disclosed. For this end, the UE, receiving first uplink grant information and logical channel priority information associated with the first uplink grant, constructs a first data unit including data from one or more radio bearers with first logical channel priority corresponding to the logical channel priority information. And, the UE transmits the first data unit to a network.

Abstract: A method for transmitting sidelink data by a user equipment (UE) in a wireless communication system, includes determining whether more sidelink data is available in a Sidelink Traffic Channel (STCH) than can be transmitted in a current Sidelink Control (SC) period; selecting a sidelink grant from a resource pool when more sidelink data is available in the STCH than can be transmitted in the current SC period; and transmitting sidelink data available in the STCH based on the selected sidelink grant, wherein the UE considers the selected sidelink grant to be a configured sidelink grant occurring in those time intervals starting at the beginning of an available SC period which starts at least N time intervals after a time interval in which the sidelink grant was selected, where N is a positive integer.

Abstract: In the present invention, a user equipment (UE) receives semi-persistent scheduling (SPS) configuration information on N SPS resource configurations, where N is an integer larger than 1. The UE receives an SPS command to activate or deactivate each of multiple SPS resource configurations among the N SPS resource configurations. The UE performs downlink reception or uplink transmission in an SPS resource corresponding to an SPS resource configuration among activated SPS resource configurations. The SPS command includes information indicating each of the multiple SPS resource configurations and information indicating whether a corresponding SPS resource configuration is activated or deactivated.

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.
