    摘要： In a BWA communication system, an MSS changes its connection from the serving BS to the target BS, and sends the target BS a report indicating that the MSS will change its connection upon detecting occurrence of a pingpong effect in a process of performing a network re-entry operation with the target BS. The target BS sends the serving BS a notification indicating that the MSS will change its connection. Upon receiving from the MSS a report indicating that it will change its connection to the serving BS, the serving BS allocates a contention-free-based ranging resource to the MSS so that the MSS connects a communication service with the serving BS using the contention-free-based ranging resource, minimizing a service delay.

    摘要： A system and method for dynamically allocating a frame cell (FC) and subchannel (FC/subchannel) is disclosed. An access point receives channel quality information (CQIs) which is fed back from a plurality of access terminals on an FC-by-FC basis, and determines a modulation and coding scheme (MCS) to be applied to each of the access terminals. If access terminals whose FCs/subchannels must be changed are detected from the plurality of the access terminals, the access point sends an FC/subchannel change request for the detected access terminals to an access router. The access router generates weights for all FCs, allocates an FC/subchannel set by selecting a predetermined number of FCs/subchannels considering the weights of the FCs for the access terminals corresponding to the received 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 received from the access router for the access terminals whose FCs/subchannels must be changed, based on CQIs last received from the access terminals whose FCs/subchannels must be changed.

    摘要翻译： 公开了一种用于动态分配帧单元（FC）和子信道（FC /子信道）的系统和方法。 接入点接收在FC-by-FC的基础上从多个接入终端反馈的信道质量信息（CQI），并且确定要应用于每个接入终端的调制和编码方案（MCS）。 如果从多个接入终端检测到其FC /子信道必须被改变的接入终端，则接入点向接入路由器发送检测到的接入终端的FC /子信道改变请求。 接入路由器为所有FC产生权重，考虑到与接收的FC /子信道改变请求对应的接入终端的FC的权重，通过选择预定数量的FC /子信道来分配FC /子信道集，并且发送关于所分配的 FC /子通道设置到接入点。 接入点根据从接入路由器接收的FC /子信道集信息，从FC /子信道接收到的FC /子信道必须改变的FC /子信道集中选择并分配特定的FC /子信道， FC /子通道必须更改。

    摘要： A method for measuring/reporting a channel quality in a broadband wireless access communication system. The method for reporting channel qualities of active BS and neighbor BSs measured by an MSS to the active BS when the MSS exists in a specific area covered by the active BS and neighbor BSs in a communication system includes the steps of: a) receiving channel quality report information indicative of channel periods of the channel qualities from the active BS, and receiving channel quality measurement information associated with individual channel qualities of the neighbor BSs and the active BS from the active BS; b) measuring SINRs of the neighbor BSs and the active BS according to the channel quality measurement information; and c) reporting the measured SINRs of the neighbor BSs and the active BS to the active BS.
