摘要： A method and a system is disclosed for controlling a sleep mode in broadband wireless access communication system. The subscriber terminals are managed by grouping the subscriber terminals in a broadband wireless access communication system, so an efficiency for controlling the sleep mode of the broadband wireless access communication system may increase. A further advantage is provided that each point of time for transmitting a paging message of each group is established differently from each other within a unit time slot for controlling the sleep mode, such that subscriber terminals are managed according to groups. Another advantage is provided that the base station can previously find subscriber terminals awaking at each point of time for transmission the paging message of each other from among subscriber terminals having the sleep mode, so an efficiency for controlling the sleep mode of the broadband wireless access communication system may increase.

摘要： A decoding apparatus and method of a terminal in a wireless communication system are provided. A carrier to interference and noise ratio (CINR) estimator estimates a CINR value of a received signal, and a controller generates a modulation and coding scheme (MCS) level candidate set satisfying the estimated CINR value and a target packet error rate (PER) based on a look-up table. A decoder switch determines if an MCS level of a burst is included in the MCS level candidate set when the burst having no connection identifier (CID) information exists in a corresponding frame, and determines to decode the corresponding burst if the MCS level of the burst is included in the MCS level candidate set and to discard the burst otherwise.

摘要： Disclosed is a system and a method for provisioning service flows in broadband wireless access communication. In a broadband wireless access communication system, if a base station receives a registration request message from a mobile station, and if the base station inserts information about service flows to be provisioned by a base station into a registration response message and transmits the registration response message to the mobile station after the registration request message is received, the mobile station determines if the mobile station transits into a normal operation mode corresponding to the information and exactly recognizes a time point at which the mobile station goes into the normal operation mode.

A buffer descriptor (BD) generator generates a BD making reference to constituent elements constituting a MAC protocol data unit (PDU), if there is a medium access control (MAC) service data unit (SDU) to be transmitted. A direct memory access (DMA) controller generates the MAC PDU from the MAC SDU according to the BD.

摘要： An apparatus and a method for estimating a carrier to interference and noise ratio (CINR) in a communication system. The CINR value is precisely estimated by removing the error floor value, which is caused by the inaccurate sliding average window SAW channel estimation value, from the CINR estimation value. Since the CINR value is precisely estimated, performance of the adaptive power control or the adaptive modulation and coding device is improved.
