    • Provided are a transmitting apparatus and voice data transmitting and receiving methods for providing VoIP services. When a call is started and an analog signal including a voice signal is input, the transmitting apparatus divides the analog signal into a plurality of voice data packets for transmission. Here, the plurality of voice data packets are generated by sampling with different phases in the same frequency. In addition, the transmitting apparatus inserts a time indication bit that is changed every transmission period into each of the voice data packets and transmits the voice data packets, and distinguishes voice data corresponding to a current transmission period based on the time indication bit.

    • Provided are a method and an apparatus for transmitting resource allocation information. In the case when a wireless resource for a new terminal is fixedly allocated to a fixed allocation zone, the apparatus for transmitting resource allocation information determines a resource allocation method of allocating the wireless resource and determines an allocation form of a resource that is allocated by a resource allocation method to select any one information displaying method of a plurality of information displaying methods of displaying allocation information on the allocated resource on the basis of the determined resource allocation method and resource allocation form. Next, the resource allocation information is generated and transmitted on the basis of the selected displaying method.
