摘要:
A method for allocating a band Adaptive Modulation and Coding (AMC) channel in a wireless communication system that divides a full frequency band into a plurality of subcarrier bands and includes subchannels, each of which is a set of a predetermined number of neighbor subcarrier bands. Upon recognizing a need for a band AMC channel, a subscriber station (SS) sends a request for allocation of the band AMC channel to a base station (BS). Upon receiving the band AMC channel allocation request, the BS determines if it can allocate the band AMC channel requested by the SS, considering a resource situation of the BS, and transmits information on the determination to the SS.

A method for performing fast base station switching in an mobile station capable of using multiple frequency assignments in a wireless communication system are provided, in which initial network entry to a base station managing at least two frequency assignments is performed in one of the at least two frequency assignments, overlay mode support information and FA information about the at least two frequency assignments are acquired by the initial network entry, the overlay mode support information indicating whether the base station supports multiple frequency assignments, the base station is notified that the mobile station will operate in an overlay mode using multiple frequency assignments based on the acquired information, and signals are transmitted and received to and from the base station in the at least two frequency assignments.

Disclosed is a system and a method of signal transmission/reception by a mobile station in a wireless communication system. The method includes: transmitting a first sub-band preparation indicator, which indicates that the mobile station has been prepared for transmission/reception of a signal through a first sub-band, to a base station through a primary band; transmitting a first sub-band failure indicator to the base station through the primary band upon detecting failure in transmitting the first sub-band preparation indicator; receiving sub-band information on a second sub-band, which is different from the first sub-band, from the BS through the primary band; and acquiring synchronization with the second sub-band, so as to enable transmission/reception of a signal through the second sub-band based on the sub-band information.

A method for transmitting and receiving signals using multiple frequency band in a wireless communication system are provided, in which a BS determines whether an MS is to use a plurality of FAs, selects the plurality of FAs if it is determined that the MS is to use the plurality of FAs, transmits FA information about the selected FAs to the MS, and transmits and receives signals to and from the MS in the selected FAs.

摘要:
A method of operating a Base Station (BS) in a broadband wireless communication system to resume an extended real-time Polling Service (ertPS) is provided. The method of operating the BS includes detecting a codeword received through a Channel Quality Indicator (CQI) channel, and upon receiving a CQI CHannel (CQICH) codeword for requesting resumption of an extended real-time Polling Service (ertPS) connection from a Mobile Station (MS), allocating to the MS an uplink resource corresponding to the largest maximum sustainable traffic rate of at least one ertPS connec established to the MS.
摘要:
A method for controlling operation modes of a medium access control layer by a mobile subscriber station in a broadband wireless access communication system including the mobile subscriber station and a serving base station providing service to the mobile subscriber station is provided. The method includes the steps of: mode-transiting into an idle mode when there is no data transmission between the serving base station and the mobile subscriber station during a predetermined first time interval in an awake mode; detecting movement of the mobile subscriber station in the idle mode into another paging zone covering a target base station, which is different from a paging zone covering the serving base station; and mode-transiting into the awake mode and performing location update together with the target base station when the movement of the mobile subscriber station is detected.
