摘要:
An apparatus and method for controlling a sleep mode in a wireless access communication system. The apparatus determines a predetermined number of groups for grouping at least one subscriber terminal according to type information of a paging interval equal to the sum of the sleep interval and the listening interval, and registers the subscriber terminal in one group from among the groups on the basis of the paging interval type of the subscriber terminal. Upon receipt of the group information, the apparatus controls a base station to pre-recognize a terminal woken up at a predetermined time from among a plurality of terminals entering the sleep mode, resulting in reduction of the number of unnecessary paging message transmissions and improved efficiency of the wireless access communication system.

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.

摘要:
A method for controlling an operation mode of a terminal in a broadband wireless access communication system. In the method, the operation modes of the terminal is subdivided, such that it is possible to effectively reduce power consumption of the terminal. In particular, the method allows the terminal to operate in the inactive mode in which the terminal having no traffic with a base station more than a predetermined time returns a CID of the terminal to the base station and keeps only a downlink with the base station, so that it is possible to prevent power of the terminal from being consumed during the sleep mode. Additionally, because a CID is not assigned to the terminal in the inactive mode, resources of the base station are efficiently used.

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.

An apparatus and method for regulating arrangement of pilot subcarriers to improve a channel estimation throughput in a wireless communication system using an Orthogonal Frequency Division Multiplexing (OFDM) scheme are provided. The apparatus includes a pilot pattern manager for providing control such that pilots are non-uniformly generated according to a distance of a preamble in order to provide a constant link throughput of the frame when the downlink frame is generated.
