摘要： The present invention relates to a reference current circuit. The reference circuit comprises a low-level current bias circuit, a voltage proportional-to-absolute temperature generator for creating a proportional-to-absolute temperature voltage (VPTAT), and a MOSFET-based constant-IC regulator circuit. The MOSFET-based constant-IC regulator circuit includes a constant-IC input and constant-IC output. The constant-IC input is electrically connected with the VPTAT generator such that the voltage proportional-to-absolute temperature is the input into the constant-IC regulator circuit. Thus the constant-IC output maintains the constant-IC ratio across any temperature range.

摘要： A method and apparatus for selecting a TFC in a wireless transmit/receive unit (WTRU) is disclosed. The WTRU estimates a transmit power for each of a plurality of available transport format combinations (TFCs). A TFC is selected for an uplink dedicated channel and a TFC is selected for an enhanced uplink (EU) channel. The TFC for the dedicated channel is selected first and independently of the TFC selection of the EU channel. The TFC for the EU channel is selected within a remaining WTRU transmit power after the TFC selection for the dedicated channel.

摘要： 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.
摘要翻译：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。

摘要： 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.

摘要： 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.

摘要： A method and apparatus for selecting multiple transport formats and transmitting multiple transport blocks (TBs) in a transmission time interval simultaneously with multiple hybrid automatic repeat request (H-ARQ) processes in a wireless communication system are disclosed. Available physical resources and H-ARQ processes associated with the available physical resources are identified and channel quality of each of the available physical resources is determined. Quality of service (QoS) requirements of higher layer data to be transmitted are determined. The higher layer data is mapped to at least two H-ARQ processes. Physical transmission and H-ARQ configurations to support QoS requirements of the higher layer data mapped to each H-ARQ process are determined. TBs are generated from the mapped higher layer data in accordance with the physical transmission and H-ARQ configurations of each H-ARQ process, respectively. The TBs are transmitted via the H-ARQ processes simultaneously.

摘要： 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.

摘要： A method and apparatus for efficient operation of an enhanced dedicated channel (E-DCH) are disclosed. A physical layer processing includes computation of various control parameters followed by actual processing of the data to be transmitted. In accordance with the present invention, the computation of the control parameters is performed asynchronously from the associated data operation. A medium access control (MAC) layer provides information needed for computation of the control parameters to the physical layer as early as possible, while the data is being processed in parallel. The provided data includes a hybrid automatic repeat request (H-ARQ) profile, a transport block size, power offset, or the like. By sending this data to the physical layer before MAC-e processing is complete, the latency constraint can be significantly relaxed.
