摘要： In various embodiments, a system and method for providing uplink (UL) power control for a wireless mobile station (MS) includes, after transmission of an unanswered bandwidth request by the MS, incrementally boosting an UL transmit power of one or more subsequent bandwidth requests by the MS to a boosted UL power level at which UL bandwidth is allocated to the MS by the BS; selectively reporting the boosted UL power level to the BS immediately after the UL transmit power has been boosted; and selectively controlling the boosted UL power level by the BS responsive to the boosted UL power level reported to the BS. A MS is configured to carry out the UL power control method and a BS is configured to generate MS UL power control commands based, at least in part, upon the UL power level reported to the BS.

摘要： An apparatus and method of configuring a number of retransmissions for an automatic repeat request (ARQ) scheme (e.g., hybrid ARQ) includes configuring one or more first maximum retransmission numbers based on respective one or more first predetermined values and independent of a second maximum retransmission number. The first maximum retransmission numbers may indicate a maximum number of retransmissions related to respective service flows operational with the base station. The second maximum retransmission number may indicate a maximum number of retransmissions related to control messages transmitted in the wireless network, and may be configured based on a second predetermined value. The configuration of the first maximum retransmission numbers may include the maximum retransmissions numbers associated with a specific user in communication with the base station. Further, at least one of the first maximum retransmission numbers of a particular user may be reconfigured to a third predetermined value.

摘要： A method of operating a communication system comprises establishing a wireless device release time interval for a wireless device release timer at an access node upon establishing an initial network connection between a wireless device and the access node. An initial synchronization process is performed between the wireless device and the access node. The method continues with the access node sending an unsolicited synchronization message to the wireless device and starting the wireless device release timer. A second synchronization process is performed and upon successful completion of the second synchronization process, a success status synchronization response message is sent by the access node to the wireless device. The access node receives a synchronization confirmation message from the wireless device that comprises an identifier corresponding to the identity of the wireless device and upon receiving the confirmation message, the access node cancels the wireless device release timer.

摘要： A method of operating a communication system comprises sending a frame by an access node to a wireless device where the frame comprises a packet. A counter is initialized and a timer for each frame is initiated. The method continues with the access node determining if a response associated with the packet is received before the expiration of the timer. If the response is received prior to the expiration of the timer, the counter and the timer are reset. If a response is not received prior to the expiration of the timer, the counter is incremented. Upon the counter meeting a criteria of a certain quantity of lost packets, the access node performs a synchronization process.

摘要： The present invention provides a virtual machine system and a method for sharing a graphics card amongst virtual machines. A VMM of the virtual machine system is provided with a resource-converting module, which converts data exchanged between a graphics card drive module of a GOS in the foreground and the graphics card based on a resource-converting table, and also intercepts accesses to the real graphics card by a GOS in the background and then responds to its operations on the graphics card. The VMM is further provided with a switching module, which alters a state of a VM based on a command for switching the VM, saves a graphics card state before the VM is switched to the background and restores the stored graphics card state to the graphics card when the VM is switched back to the foreground. Further, the GOSs each comprise a graphics card drive module corresponding to the real graphics card for accessing the real graphics card. The systems and the methods according to the present invention enable the GOSs to access the real graphics card, and also enable switching among a plurality of virtual machines.
摘要翻译：本发明提供一种在虚拟机之间共享图形卡的虚拟机系统和方法。虚拟机系统的VMM设置有资源转换模块，该资源转换模块基于资源转换表转换在前台的GOS的图形卡驱动模块与图形卡之间交换的数据，并且还拦截对真正的图形卡由GOS在后台响应其在显卡上的操作。 VMM还具有切换模块，其基于用于切换VM的命令改变VM的状态，在VM切换到背景之前保存图形卡状态，并将存储的图形卡状态恢复到图形卡当VM切换回前台时。此外，GOS各自包括对应于用于访问真实图形卡的真实图形卡的图形卡驱动模块。根据本发明的系统和方法使得GOS能够访问真实图形卡，并且还使得能够在多个虚拟机之间进行切换。
