Abstract: The present invention discloses methods and apparatuses for fast resource scheduling at the base station and fast transport format combination selection at the UE by using different pointers in base station and user equipment of wireless network. The TFCS in base station and UE are divided into TFCsbs each of which is a set of TFCs with the same transmission rate or the same transmission power, in the resource scheduling process at the base station, a pointer is used to select a proper TFCsb according to the resource request information from the UE and then inform UE of the relevant information. UE select the proper TFC by using another pointer from the TFCsb chosen at the base station. Because each of the scheduling process at the base station and the TFC selection process at the UE uses a pointer separately, the two processes can go more efficiently individually.

Abstract translation: 本发明公开了一种在基站上进行快速资源调度的方法和装置，并且通过在基站和无线网络的用户设备中使用不同的指针，在UE处进行快速传输格式组合选择。 在基站和UE中的TFCS被分成TFCsbs，每个TFCs是具有相同传输速率或相同发射功率的一组TFC，在基站的资源调度过程中，使用指针来选择适当的TFCsb， 来自UE的资源请求信息，然后通知UE相关信息。 UE通过使用从基站选择的TFCsb的另一个指针来选择适当的TFC。 由于基站处的每个调度处理和UE的TFC选择过程分别使用指针，所以两个进程可以单独地更有效地进行。

Abstract: Messages transmitted between a receiver and a transmitter are used to maximize a communication data rate. In particular, a multicarrier modulation system uses messages that are sent from the receiver to the transmitter to exchange one or more sets of optimized communication parameters. The transmitter then stores these communication parameters and when transmitting to that particular receiver, the transmitter utilizes the stored parameters in an effort to maximize the data rate to that receiver. Likewise, when the receiver receives packets from that particular transmitter, the receiver can utilize the stored communication parameters for reception.

Abstract: An apparatus and method for transmitting/receiving channel quality information (CQI) in a communication system having a frame including subchannels corresponding to the same frequency reuse factor or different frequency reuse factors. A base station (BS) allocates at least one of the subchannels in the frame to a subscriber station (SS), and sends a transmission request for a CQI for a subchannel desired to be received, to the SS. The SS measures channel quality for individual subchannels requested by the BS in response to the CQI request, and transmits the measured channel quality to the BS.

Abstract: A user equipment (UE) in a mobile communications system is operated in a manner that alleviates or avoids an overload condition in the UE. This involves operating a receiver of the UE to receive one or more data blocks via a channel. In response to a user equipment overload condition being detected, a channel quality indicator (CQI) value is reported to a serving base station, wherein the reported CQI value represents a channel quality that is lower than an actual quality of the channel. The UE is then operated in a manner that is consistent with the reported CQI value. UE overload conditions include overheating, and an inability to process received data blocks at the rate at which they are being received.
