摘要： A compensated switched capacitor circuit comprises a switched capacitor circuit and a compensation circuit. The compensation circuit generates a reference current that varies under closed loop control to maintain a targeted slew rate for charging a reference capacitor that is determined by the input clock frequency. The switched capacitor circuit’s output amplifier is configured such that its output current varies in proportion to the reference current. Thus, by configuring the reference capacitor to track the effective capacitance of the switched capacitor circuit, the settling time of the switched capacitor circuit may be made relatively insensitive to the value of and changes in the effective capacitance over a range of clock frequencies. The compensation circuit may include a clock reconditioning circuit that the switched capacitor circuit is clocked at a desired duty cycle.

摘要： Methods and apparatus are disclosed for compressing and decompressing data to reduce bandwidth requirements in transmissions of predistorted signals between a processing node and a remote transmitting node of a power amplifier with digital predistortion (PA-DPD) system. In the processing node, predistorted signals are decomposed into a high-dynamic range signal of a first sample rate and a low-dynamic range signal of a second sample rate greater than the first sample rate. Samples of both signals are combined to generate a compressed signal for transmission to the remote transmitting node, which decompresses the compressed signal to restore the predistorted signal.

摘要： Techniques for handling ciphering keys in a mobile station comprising a mobile equipment (ME) and a Universal Subscriber Identity Module (USIM) are disclosed. An example method includes obtaining a UMTS cipher key (CK), integrity key (IK), and ciphering key sequence number (CKSN) from the USIM, deriving a 128-bit ciphering key (Kc-128) from the CK and the IK, and storing the Kc-128 and the CKSN on the mobile equipment, separate from the USIM. The stored CKSN is associated with the stored Kc-128, so that the Kc-128's correspondence to the most current UMTS security context can be tracked. This example method applies to the generation and storage of a 128-bit ciphering key for either the packet-switched or circuit- switched domains. A corresponding user equipment apparatus is also disclosed.

摘要： A wireless communication network is configured to provide distributed diversity transmissions, wherein different diversity-coded versions of the same information signal are transmitted from each of two or more network sectors. The diversity-coded versions of the information signal are based on space-time or space-frequency codes, and the information signal may comprise a dedicated channel signal targeted to an individual user or a broadcast signal targeted to one or more users. Thus, spaced-apart network transmitters, which may be located at the same cell site, or at different cell sites, are configured to transmit diversity-coded versions of a given information signal and, in this manner, the advantages of space-time and/or space frequency transmission coding may be applied across multiple sectors of a communication network. Such transmissions may be used to improve soft and softer handoff reception of dedicated channel signals, and to improve reception of Broadcast-Multicast Services (BCMCS) signals, or the like.

摘要： A wireless communication network includes radio base stations of a first type that support dedicated channel packet data service and radio base stations of a second type that additionally support shared channel packet data service. A base station controller evaluates pilot signal strength reports to determine whether to serve a given mobile station on a shared packet data channel or on a dedicated packet data channel. Evaluation may comprise determining whether any pilot signals in the report correspond to radio base stations of the second type. If so, and if one or more service criteria are met, the controller serves the mobile station on a shared packet data channel, and otherwise serves it on a dedicated packet data channel. The controller may control or otherwise limit the mobile station's active set based on identifying pilot signals in the report that correspond to radio base stations of the second type.

摘要： A scheduler (60) at a base station (36) may schedule packet data traffic based on a ranking metric that varies directly with the mobile station's scheduling downlink transmission rate and a delay factor indicative of the staleness of the corresponding queued data. The ranking metric may advantageously vary in a direct non-linear fashion with the delay factor to allow for delay sensitive data, such as VoIP data, to be scheduled with increased urgency when quality of service is about to be compromised. The scheduler may attempt to pack a multi-user downlink physical layer packet by selecting a tentative rate and determining if an aggregate amount of data in the packet may be increased by transmitting the packet at a lower rate. If so, additional queued data is added to the packet and the transmission rate for the packet is lowered. Such an approach allows for greater link efficiency to be achieved.

摘要： A method of providing packet data service is based on selectively switching packet data traffic for a mobile station operating in a boundary region between two service areas from a shared packet data channel to a dedicated packet data channel, or vice versa. For example, a source base station can be configured to switch packet data traffic for a mobile station from a shared packet data channel to a dedicated packet data channel as it approaches a shared channel service boundary. Additionally, the source base station can be configured to change the packet data service to the mobile station from a dedicated packet data channel to a shared packet data channel, such as when the mobile station moves back into the source base station's service area.

摘要： Call setup latency for a packet data call dormant reactivation in a cdma2000 wireless communication network is reduced by bypassing service negotiation and/or R LP Sync exchange procedures using values stored at the base station controller B SC. Previously negotiated parameters may be used to bypass service negotiation. A non-zero round trip time RTT value, calculated by a previously performed RLP Sync exchange, is stored at the BSC, and transmitted to the mobile station MS upo n dormant reactivation. The MS uses the RTT to calculate a RLP REXMIT_TIMER value, bypassing a RLP Sync exchange with the BSC. The service configuration parameters and non-zero RTT may be stored at the BSC in the RLP BLOB of a service configuration record SCR, which may be transmitted to the MS in a service connect message SCM. The SCR may store multiple records, each containing negotiated service configuration parameters and/or a non-zero RTT associated with a service instance, selected by a service reference identifier SRID transmitted by the MS.

摘要： A method and apparatus provide network-based flow control for mobile station having data connections to the network. In an exemplary embodiment, a Packet Control Function (PCF) in a Radio Access Network (RAN) requests that a Packet Data Serving Node (PDSN) in a Packet Core Network (PCN) turn flow control on and off as needed for mobile station data connections. That is, if the PCF receives data from the PDSN for delivery to a mobile station that the PCF determines to be unavailable, the PCF requests that data transfers from the PDSN be suspended for that mobile station. Such suspension avoids needless continued transfer of undeliverable data to the PCF. The PCF monitors or otherwise determines whether a flow-controlled mobile station has become available again and, if so, notifies the PDSN so that it can lift the suspension and resume data transfers as needed.
摘要翻译：一种方法和装置为具有到网络的数据连接的移动站提供基于网络的流量控制。在示例性实施例中，无线电接入网络（RAN）中的分组控制功能（PCF）请求分组核心网络（PCN）中的分组数据服务节点（PDSN）根据移动站数据的需要开启和关闭流量控制连接。也就是说，如果PCF从PDSN接收到用于传送给PCF确定不可用的移动站的数据，则PCF请求从该移动站暂停从PDSN的数据传送。这种暂停避免不必要地将无法投递的数据传输到PCF。 PCF监视或以其他方式确定流量控制的移动台是否已经再次可用，如果是，则通知PDSN，使得它可以根据需要提升暂停并恢复数据传输。

摘要： A mobile station downloading an object over a broadcast channel uses a repair service to obtain data that was received in error during the original broadcast. The mobile station sets a repair threshold for the download object and invokes repair if the amount of errors is less than the repair threshold. If the amount of errors exceeds the repair threshold, the mobile station treats the download attempt as having failed and may send a new request if download is still desired.
摘要翻译：通过广播频道下载对象的移动台使用修复服务来获得在原始广播期间错误接收的数据。移动站设置下载对象的修复阈值，如果错误量小于修复阈值，则调用修复。如果错误量超过修复阈值，则移动台将下载尝试视为失败，并且如果仍需要下载，则可以发送新请求。
