Abstract: Methods and devices in a wireless communication system are provided. A method includes receiving, from a base station, a radio resource control (RRC) reconfiguration message configuring a medium access control (MAC) parameter for the terminal, identifying an uplink grant for a MAC protocol data unit (PDU); identifying that skip uplink transmission information indicating for the terminal to skip an uplink transmission is configured in the RRC reconfiguration message and that the uplink grant is addressed to a cell-radio network temporary identifier (C-RNTI) or is a configured uplink grant; and skipping a generation of the MAC PDU for the uplink grant, in case that a MAC service data unit (SDU) for the MAC PDU does not exist, and the MAC PDU includes only a padding buffer status report (BSR).

Abstract: A method for reporting performance of a terminal in a mobile communication system includes the steps of receiving a request for performance reporting from a base station, determining an indicator of whether a delay time related operation that the terminal supports is in correspondence with the request which corresponds to a pre-set condition, and transmitting a message including the determined indicator to the base station. The size of the performance reporting message may be minimized in reporting the performance of the terminal.
