摘要： Methods and apparatus are provided for performing a handover by a serving base station in a communication system. A handover request message is received from a mobile station. A first handover response message is transmitted to the mobile station. The first handover response message includes a list of at least one neighbor base station. A handover indication message including a value of a handover indication type field is received. The value is determined by the mobile station from among at least two values individually indicating at least one of a handover cancel and the handover rejection. The value representing the handover cancel indicates that the mobile station intends to cancel a handover procedure, and the value representing the handover rejection indicates that the mobile station intends to reject performing handover with any of the at least one neighbor base stations in the list.

摘要： Dynamically allocating a frame cell (FC)/subchannel in a mobile communication system by an access point that receives channel quality information (CQIs) fed back from access terminals, determines a modulation and coding scheme (MCS) to be applied to the access terminals based on the CQIs, and if access terminals whose FCs/subchannels must be changed are detected from the access terminals, sends an FC/subchannel change request to an access router. The access router allocates an FC/subchannel set by selecting a number of FCs/subchannels according to the FC/subchannel change request, and transmits information on the allocated FC/subchannel set to the access point. The access point selects and allocates a particular FC/subchannel from among FCs/subchannels in the FC/subchannel set information to the access terminals whose FCs/subchannels must be changed, based on CQIs last received from the access terminals.

摘要： A method and apparatus for transmitting a DL-WUCH for a mode transition in a sleeping state in a broadband wireless communication system are provided. In the broadband wireless communication system, a base station (BS) transmits control information to a plurality of subscriber stations (SSs) on a common control channel. To demodulate a control channel signal received from the BS, an SS receives a wakeup channel signal which indicates whether the control channel signal includes control information for the SS, reads a wakeup channel indicator at a predetermined position assigned to the SS of the wakeup channel signal, and determines whether to demodulate the control channel signal according to the wakeup channel indicator.

摘要： Disclosed is a system and a method for controlling a handover of a mobile subscriber station in a broadband wireless access communication system. When serving base station determines to perform a handover of the mobile subscriber station, neighbor base stations to which the mobile subscriber station can be handed over, from among neighbor base stations of the mobile subscriber station, are determined based on a service quality level of service being currently provided to the mobile subscriber station. A handover request signal containing information related to the determined neighbor base station to which the mobile subscriber station can be handed over is transmitted to the mobile subscriber station. The serving base station receives from the mobile subscriber station in response to the request of the handover information about one neighbor base station to which the mobile subscriber station will be handed over, and informs the neighbor base station that the mobile subscriber station will be handed over to the neighbor base station.
