摘要： Various embodiments of the present disclosure relate to a method for transmitting and receiving data in a wireless communication system. A method by which a terminal transmits a power headroom report (PHR) in a wireless communication system, according to one embodiment of the present disclosure, can comprise the steps of: receiving signaling information including at least one indicator indicating PHR reporting for at least one cell among cells for a dual connectivity operation; and transmitting at least one PHR for the at least one cell corresponding to the at least one indicator. The at least one cell can be a primary cell (Pcell) serving the terminal and/or a primary secondary cell (PScell) serving the terminal.

摘要： Method for radio communication with base station, by user equipment (UE), apparatus in UE for radio communication with base station, a method for radio communication with a UE by a base station, and an apparatus in a base station for radio communication with a UE are provided. The method for radio communication with a base station, by a UE, includes determining whether to start a first timer based on a predetermined condition, in response to a buffer status reporting triggered; starting the first timer in response to the predetermined condition being satisfied; in response to an uplink resource for a buffer status report transmission being available before the first timer expires, transmitting an uplink packet including a buffer status report using the available uplink resource; and in response to no uplink resource for the buffer status report transmission being available and the first timer expiring, transmitting a scheduling request to the base station.

摘要： Methods and apparatuses are provided for transmitting and receiving system information (SI). A method for receiving SI by a user equipment (UE) in a mobile communication system includes receiving, by the UE, the SI including first partial bits of a system frame number (SFN) without second partial bits of the SFN on a broadcast channel (BCH) at a first subframe of a radio frame, the first partial bits of the SFN having the same value during a predetermined N successive radio frames of a BCH transmission period, where N is a positive integer; and acquiring, by the UE, the second partial bits of the SFN for the radio frame, the second partial bits of the SFN having different values in different radio frames of the predetermined N successive radio frames of the BCH transmission period.
