The present invention is directed to defining forward link (FL) control signaling and bitmap signaling for indicating the channelization codes to be used by access terminals in a mobile communication system. In one aspect of the present invention, a method of allocating resources for a plurality of mobile communication terminals in a wireless communication system is provided. The method includes allocating at least one of the plurality of mobile communication terminals to a first group and at least one of the plurality of mobile communication terminals to a second group according to at least one of a location of and a QoS requirement of each of the plurality mobile communication terminals, generating resource allocation information for each of the first group and second group and transmitting the resource allocation information to each of the plurality of mobile communication terminals.
