Apparatus and method for uplink scheduling in wireless communication system

An apparatus for allocating a resource at a base station in a wireless communication system that provides a Voice over Internet Protocol (VoIP) service, the apparatus comprising:

• a receiver configured to receive a signal;
• a controller configured to determine one or more terminals for providing the VoIP service during a next time section, and determine mute section set information of a current time section and the next time section for the one or more terminals;
• and
• a resource allocation unit configured to allocate an amount of a resource of the next time section to at least one terminal whose next time section is not set to a mute section, wherein the amount of resource of the next time section is based on whether the current time section is set to a mute section or not set to a mute, and
• wherein the controller is configured to determine the mute section set information of a current time section and the next time section of each terminal using a control message received from the one or more terminals via the receiver.

A method for transmitting mute section set information at a terminal of a wireless communication system that provides a Voice over Internet Protocol (VoIP) service, the method comprising:

• determining whether VoIP connection with a serving base station is activated during a next time section;
• when the VoIP connection with the serving base station is activated during the next time section, determining mute section set information of a current time section and the next time section;
• and
• transmitting the mute section set information of the current time section and the next time section to the serving base station, wherein an amount of resource of the next time section is based on whether the current time section is set to a mute section or not set to a mute section, and
• wherein the transmitting of the mute section set information of the current time section and the next time section to the serving base station comprises transmitting the mute section set information of the current time section and the next time section to the serving base station using a mute section control message.

An apparatus for transmitting mute section set information at a terminal of a wireless communication system that provides a Voice over Internet Protocol (VoIP) service, the apparatus comprising:

• a controller configured to, when VoIP connection with a serving base station is activated during a next time section, determine mute section set information of a current time section and the next time section;
• and
• a transmitter configured to transmit the mute section set information of the current time section and the next time section to the serving base station, wherein an amount of resource of the next time section is based on whether the current time section is set to a mute section or not set to a mute section,
• wherein the transmitter is configured to transmit the mute section set information of the current time section and the next time section to the serving base station using a mute section control message.
