摘要： A method and apparatus for dynamically allocating and releasing a Channel Quality Information CHannel (CQICH) to and from a Mobile Station (MS) in a Base Station (BS) communicating with a plurality of MSs on a common radio channel in a wireless communication system are provided, in which the BS determines whether the MS is under a first group, when a CQICH is to be allocated to the MS, determines whether any data transmission has occurred for a CQICH allocation period preset for the first group and counted from a reallocation time, if the MS is under the first group, and groups the MS to a second group and reallocates a CQICH to the MS, the second group having a lower priority level than the first group, if no data transmission has occurred for the CQICH allocation period.

摘要： An apparatus and a method for selectively retransmitting data according to a channel state in a wireless communication system are provided. The method includes determining retransmission information of a receiver from feedback information received from the receiver, determining a retransmission scheme for the receiver using the retransmission information of the receiver, and performing a retransmission process with the receiver according to the determined retransmission scheme. In a good channel state, the data is retransmitted using the retransmission scheme to thereby enhance the reliability of the data delivery and the reception performance. In a bad channel state, the data is not retransmitted to thereby reduce a waste of resources in the data retransmission.

摘要： An apparatus and method for controlling operation states of a medium access control layer by a mobile subscriber station (MSS) in a broadband wireless access communication system. The method includes: state-transitioning into a sleep state or an idle state when there is no data transmitted between a base station and the MSS during a predetermined first time interval in an awake state; and performing a location change in the idle state when the mobile subscriber station moves from a first paging zone to a second paging zone, and state-transiting into the awake state when the mobile subscriber station in the idle state detects a paging to the mobile subscriber station. The method minimizes power consumption and maximizes efficiency in use of radio resources.

摘要： A system for performing network re-entry upon handover of a mobile subscriber station (MSS) to a target base station (BS). Upon detecting handover of the MSS, the target BS detects network re-entry information necessary for network re-entry of the MSS from the serving BS, and transmits, to the MSS, the detected network re-entry information, information on an acknowledge (ACK) channel through which the MSS will respond that it has received the network re-entry information upon receipt of the network re-entry information, and ACK request information requesting the MSS to respond whether it has received the network re-entry information. The MSS receives the ACK channel information, and thereafter receives, from the target BS, the network re-entry information and the ACK request information, and a response transmits to the target BS which indicates that it has received the network re-entry information, through the ACK channel in response to the ACK request information.
