摘要:
The traffic indication and channel adaptation apparatus for a subscriber station in a sleep mode according to the present invention includes: a channel resource allocator for generating resource allocation information allocating an uplink channel resource to the subscriber station; a traffic indication and channel adaptation controller for generating a traffic indication message transmitted with the resource allocation information to the subscriber station, and providing a downlink data having a transmission level determined by applying an AMC level according to a CQI report message transmitted from the subscriber station; a transmitter for transmitting the uplink resource allocation information, the traffic indication message, and the downlink data to the subscriber station; and a receiver from receiving a CQI codeword or a CQI report message.

Disclosed is a method for a preamble-based bandwidth request. The present invention enables state control of a subscriber station based on the latest environment in a portable Internet system requesting a bandwidth using a preamble, and hence allows a subsequent more efficient transmission of user data. In addition, the present invention provides information for discrimination of the subscriber station transmitting the preamble as well as state control information of the subscriber station to the base station during a preamble-based bandwidth request by the subscriber station, and enables the base station to discriminate the subscriber station in the next time of data transmission with the subscriber station.

Provided is a method of scheduling packets in a mobile telecommunication. The method includes the steps of: a) calculating a normalized standard data unit (SDU) drop rate based on the number of SDUs that will be dropped if the SDUs will not transmitted in a next slot, the number of SDUs dropped unit a current slot, the number of SDUs transmitted until the current slot and a maximum SDU drop rate allowed at each session; b) selecting sessions to transmit in a next slot and deciding a transmission amount of each session at a current slot based on the normalized SDU drop rate; and c) performing the steps a) and b) until all basic units (BU) in one slot are used.
