    • A delay applied to a turn-on time for a high side switch in a switch mode power converter prevents oscillation between continuous and discontinuous conduction modes under light load conditions. The delay equalizes turn-on time for a high side switch with respect to continuous and discontinuous modes, so that turn-on time is not treated differently between the different modes. The delay value can be set for be equivalent to a propagation delay through a driver for a low side switch, in addition to a turn-off time for the low side switch. The addition of the delay element tends to maintain the switch mode power converter in a discontinuous mode under light load conditions and avoids oscillation between discontinuous and continuous conduction modes.
    • 在开关模式功率转换器中对于高侧开关的导通时间施加的延迟防止在轻负载条件下的连续导通模式和不连续导通模式之间的振荡。 延迟相对于连续和不连续模式均衡高侧开关的导通时间,使得不同模式之间的接通时间不被不同地对待。 除了低侧开关的关断时间之外,延迟值可以被设置为等于通过用于低侧开关的驱动器的传播延迟。 延迟元件的添加倾向于在轻负载条件下将开关模式功率转换器保持在不连续模式,并避免不连续和连续导通模式之间的振荡。

    • A wireless communication method and apparatus for recovering data following a serving cell change are disclosed. A wireless transmit/receive unit (WTRU) includes a status prohibit timer that delays the transmission of normal status reports that indicate the status of data, (i.e., PDUs), that was successfully received and/or not successfully received after a serving cell change status report is sent. A serving radio network controller (SRNC) transmits a sequence of packet data units (PDUs). The status prohibit timer is advanced and the WTRU sends a normal status report to the SRNC without a delay caused by the status prohibit timer. In another embodiment, the WTRU receives a radio link control (RLC) intelligence mode indicator signal that indicates whether a non-intelligent radio network controller (RNC) RLC operation or an intelligent RNC RLC operation is in effect, and the WTRU generates normal status reports based on the indication of the signal.
    • 公开了一种用于在服务小区改变之后恢复数据的无线通信方法和装置。 无线发射/接收单元(WTRU)包括状态禁止定时器,其延迟在服务小区改变之后被成功接收和/或未成功接收到的数据状态(即,PDU)的正常状态报告的传输 状态报告发送。 服务无线网络控制器(SRNC)发送分组数据单元(PDU)序列。 状态禁止定时器被提前,并且WTRU向SRNC发送正常状态报告,而没有由状态禁止定时器引起的延迟。 在另一个实施例中,WTRU接收指示非智能无线电网络控制器(RNC)RLC操作或智能RNC RLC操作是否有效的无线电链路控制(RLC)智能模式指示符信号,并且WTRU生成正常状态报告 基于信号的指示。

    • Ciphering control and synchronization for both U-plane data and C-plane signaling messages in a wireless communication network are disclosed. Ciphering entities are located in a wireless transmit/receive unit (WTRU) and a network. The ciphering entities of the WTRU and the network perform ciphering control and ciphering parameter synchronization. The ciphering may be performed with a packet data convergence protocol (PDCP) layer sequence number (SN) for user plane data, a non-access stratum SN, a radio resource control SN, or an encryption SN for a control plane message. Alternatively, the ciphering control and ciphering parameter synchronization may be performed by PDCP entities of the WTRU and the network. For ciphering parameter synchronization, HFN and SN synchronization and counter check procedures are performed by the WTRU and the network based on a synchronization command message, sequence number window information, or a counter check message exchanged between the WTRU and the network.

    • A method and apparatus for protecting high throughput (HT) stations (STAs) are disclosed. In one embodiment, a physical layer (PHY) legacy preamble transmitted by one STA is decoded by another STA that does not use a legacy preamble. In another embodiment, one STA is identified by another STA by using bits in the preamble of a packet to indicate which PHY type will be used in the remaining portion of the packet. In yet another embodiment, one STA sends ready-to-send (RTS)/clear-to-send (CTS) or CTS-to-self messages for reserving a medium in the presence of another STA of a different type than the one STA. In yet another embodiment, an access point (AP) transmits a beacon or an association message including a capability information element (IE) that indicates operation or support for a legacy preamble, HT STA preambles and a medium access control (MAC) packet transmission with HT protection mechanisms.
