Method and apparatus for signaling user equipment status information for uplink data transmission in a mobile communication system

An apparatus for transmitting user equipment (UE) status information for uplink data transmission in a mobile communication system, the apparatus comprising:

• a buffer for buffering uplink data and generating buffer occupancy (BO) information by monitoring an amount of the uplink data;
• a transmit power status (TPS) information manager for generating TPS information by monitoring uplink transmit power status;
• a UE status information generator for determining whether the BO information is to be transmitted in a current time interval, determining whether the TPS information is to be transmitted in the current time interval, if the BO information is to be transmitted in the current time interval according to a TPS period, and generating UE status information comprising the BO information and the TPS information if the TPS information is to be transmitted in the current time interval;
• a packet data unit (PDU) generator for generating a PDU comprising the UE status information;
• and
• a transmitter for transmitting the PDU after coding and modulation.

A method of transmitting user equipment (UE) status information for uplink data transmission in a mobile communication system, the method comprising the steps of:

• generating buffer occupancy (BO) information by monitoring an amount of uplink data to be transmitted;
• generating transmit power status (TPS) information by monitoring uplink transmit power status;
• determining whether the BO information is to be transmitted in a current time interval;
