摘要： In an adaptive feedback method for a cellular communication system having plural terminals feeding back channel information to an access point, the system selects one of an opportunistic mode and a polling mode as a feedback mode between an access point and the terminals on the basis of system and traffic parameters, sets up the access point and the terminals for the selected feedback mode, and feeds back the channel information from the terminals to the access point in the selected feedback mode. The adaptive feedback method changes the feedback mechanism adaptively to the system and traffic environment, making it possible to increase the system throughput as well as to decrease the MAC overhead regardless of the variation of the number of MSs.

摘要： An uplink resource allocation method is provided for transmitting a control packet on a channel different from a currently connected channel in a wireless communication system for supporting a packet based real-time service. A new format of a grant management subheader is proposed in which a piggyback request conventionally used only for the same connection can be used also for a different connection. A resource allocation request for the different connection can be made using the newly proposed grant management subheader. When the resource allocation request for a new connection is made using the grant management subheader, a resource allocation time can be reduced and loss of resources allocated for an existing connection can be minimized.
