Abstract: A WCDMA enabled user equipment device configured to have functions collectively or selectively idle to conserve power. A discontinuous receiver is used to detect and read network messages and report the messages to the computer within the WCDMA enabled user equipment device. The computer then activates functions previously powered down to receive incoming messages for the user of the device. The discontinuous receiver is also used when the device is active to read network messages, freeing a modem of the device to operate on user messaging; and therefore, enhancing user related performance.

Abstract: Techniques for dynamically selecting warm-up time for a wireless device operating in the idle mode are described. At each active interval, conditions affecting warm-up of the wireless device at a next active interval are determined. The conditions may pertain to channel conditions, operating conditions, and/or hardware configuration. A warm-up time is selected based on the determined conditions. A wake-up time for the next active interval is determined based on the selected warm-up time. The wireless device then goes to sleep until the wake-up time. In one scheme, the strongest pilot acquired in each active interval is identified, and its pilot strength is averaged to obtain an average pilot strength. The average pilot strength is compared against at least one threshold, and one of at least two possible time durations is selected for the warm-up time based on the comparison result.

Abstract: The access terminal is configured to wirelessly send to a data system a request that the data system assign an access terminal identifier (ATI) to the access terminal. The access terminal delays transmission of the request until after a user of the access terminal has employed the access terminal to request a packet data service from the data system. In some instances, the data system is an Evolution, Data Only (EV-DO) system and the access terminal identifier (ATI) is a Unicast Access Terminal Identifier (UATI) generated by the Evolution, Data Only (EV-DO) system.

Abstract: A generic quality of service (QoS) model that is not dependent on network technology is used to support QoS for communication networks utilizing different network technologies. The generic QoS model may include a superset of all QoS parameters for all network technologies being supported, e.g., 3GPP and 3GPP2. An application at a device may specify QoS for a traffic flow based on the generic QoS parameters in the superset. The generic QoS parameters may be converted to QoS parameters that are specific to a serving network. The converted QoS parameters are exchanged with the serving network and are used while exchanging traffic with the serving network.

Abstract: Techniques for modifying packet filters in a wireless communication network are described. In one scheme, packet filters may be performed with multiple operations, if needed. The operation(s) to be performed and the order of performing the operation(s) may be dependent on the number of existing packet filters to be replaced (N) and the number of new packet filters (M). If N=M, then N packet filters in a traffic filter template may be replaced with a single operation. If N>M, then M packet filters in the traffic filter template may be replaced first, and N?M packet filters may be deleted from the traffic filter template next. If N<M, then M?N new packet filters may be added to the traffic filter template first, and N packet filters in the traffic filter template may be replaced next. In another scheme, packet filters are modified with a single operation using dummy packet filters, if needed.

Abstract: A system and method are provided for programming the parallel path width in a serial-to-parallel path transceiver. Initially, the transceiver is programmed to select a link layer (layer 1) protocol, such as Gigabit Ethernet (GBE) or SONET. The method accepts serial digital data in the selected protocol at a serial interface, and differentiates the serial data into units of i bits per unit. Another programmed selection is made between n number of unique data interfaces, where each interface includes a plurality of parallel paths. The serial digital data is assigned to z selected data interfaces and transmitted. In one aspect, the serial data is assigned to m number of parallel path channels, where m is less than, or equal to z, and less than i. In another aspect, the frequency at which each data interface parallel path transmits data is selected.

Abstract: Systems and methodologies are described that enable power save mechanisms to be utilized with active direct transfers. Mobile stations in a wireless communication network can establish direct links between each other to obviate a need to transfer data via an access point. While direct links are active, the mobile stations coordinate or otherwise notify each other about power management modes to effectuate power save delivery of data via direct links. In accordance with a scheduled mechanism, mobile stations coupled via a direct link enter an active mode at a previously negotiated scheduled time after which time data transfer can occur. According to an unscheduled mechanism, one mobile station can remain awake while other enters a power save mode. The sleeping station can awaken and transmit a trigger frame to notify its peer that it is available for data transfers.

The data processor is further configured to convert the RDS data into RDS group type data or to store the RDS data. The data processor is further configured to transmit the RDS data to one or more devices outside the host system. The data processor is configured to store the RDS data if the RDS data comprises a plurality of raw RDS group data. A method is also provided for transmitting RDS data from a host system.

Abstract: System and method for transmitting data to a remote communication device to achieve desirable transmit data block size and data rate based on measurements of the communication link quality to the remote device. The method entails selecting an initial transmit data rate and power based on an initial measurement of the link quality, and a default size for the transmit data block. The data block is then transmitted to the remote, and an acknowledgement (ACK) message is received from the remote. If the ACK message indicates that the data block was properly received, the size for the next data block to be transmitted is increased. Otherwise, the size for the next data block may be decreased or remain the same. Additionally, the transmit data rate may be increased if the remote properly receives a defined number of consecutive data blocks, or decreased if the remote does not receive a defined number of consecutive data blocks.

Abstract: Techniques for detecting adjacent channel interference (ACI) in a wireless communication system are described. Input inphase (I) and quadrature (Q) samples are filtered with a first filter response to obtain filtered I and Q samples. The first filter response is designed to pass signal in an adjacent frequency channel while suppressing signals in a desired frequency channel and non-adjacent frequency channels. Correlations of the filtered I and Q samples are determined. The presence of ACI is detected based on the correlations of the filtered I and Q samples and the power of the input I and Q samples. If ACI is present, then whether the ACI is from a higher frequency channel or a lower frequency channel is determined based on one or more of the correlations. The input I and Q samples are filtered with a second filter response that is adjusted based on the detection of ACI.

Abstract: Method and apparatus for decoding code words received over a communication channel are disclosed. A radius-adaptive sphere decoding methodology reduces the number of operations in sphere-constrained search. Imposing probabilistic noise constraint on top of sphere constraint, particularly at an early stage, provides a more stringent necessary condition. Hence, many branches that are unlikely to be selected are removed in the early stage of sphere search. The trade-off between computational complexity and performance can be controlled by adjusting the pruning probability.

The device may be a receiver having a wireless interface configured to receive combined first and second signals, the first signal having data in a first frequency band and the second signal having data in a second frequency band wider than the first frequency band, wherein the first frequency band is within the second frequency band. The receiver may also be a processing system configured to recover the data in the first signal from the combined first and second signals.

Abstract: In a method for managing quality of service (QoS) resources during handoff across communication systems having different grades of QoS awareness, an access terminal (AT) determines that handoff has occurred from a QoS unaware system to a QoS aware system. The AT also determines whether there are any allocated, unrequested QoS resources. If one or more allocated, unrequested QoS resources are identified, the AT requests that the QoS aware system release the one or more allocated, unrequested QoS resources. The AT also determines whether there are any requested, unallocated QoS resources. If one or more requested, unallocated QoS resources are identified, the AT requests that the QoS aware system allocate the one or more requested, unallocated QoS resources to the application.

Abstract: A discrete-time operational transconductance amplifier (OTA) with large gain and large output signal swing is described. In an exemplary design, the discrete-time OTA includes a clocked comparator and an output circuit. The clocked comparator receives an input voltage and provides a digital comparator output. The output circuit receives the digital comparator output and provides current pulses. The output circuit detects for changes in the sign of the input voltage based on the digital comparator output and reduces the amplitude of the current pulses when a change in the sign of the input voltage is detected. The output circuit also generates the current pulses to have a polarity that is opposite of the polarity of the input voltage. The discrete-time OTA may be used for switched-capacitor circuits and other applications.

Abstract: Techniques for generating a differential output voltage between first and second output voltages that is double a differential input voltage between first and second input voltages. In one aspect, first and second capacitors of a constituent voltage doubler are charged to a differential input voltage during a charging phase. During an output phase non-overlapping in time with the charging phase, the first and second capacitors are stacked in series to generate the differential output voltage. The first and second capacitors are both coupled to a single common-mode voltage to provide a predefined common-mode output voltage. Further techniques for providing two or more constituent voltage doublers to extend the output phase are described.

Abstract: This disclosure is directed to techniques for video call setup in a mobile video telephony network. In general, the call setup techniques reduce call setup delays by preemptively retransmitting NSRP packets before expiration of the timeout period ordinarily required for receipt of an NSRP ACK packet from the remote terminal. The retransmitted NSRP packets may be retransmitted during idle periods in which the modem layer in the sending mobile terminal has received no other data for transmission of the remote mobile terminal, thereby taking advantage of idle bandwidth. Multiplex data received by the modem can be locally buffered at the modem layer for retransmission. In this manner, retransmission does not require regeneration of the original call setup messages nor multiplexing. Instead, the previously generated and multiplexed data is buffered at the modem layer for retransmission to reduce processing overhead within the mobile terminal.

Abstract: An FM radio with a wide frequency range operates in a cell phone without interfering with the VCO of the RF transceiver. The FM transceiver generates a VCO signal whose frequency varies by less than ±7% from the midpoint of a narrow first range. A synthesizer signal is generated by dividing the VCO frequency by a first divisor such that the synthesizer frequency varies over a lower frequency second range. The VCO frequency is also divided by a second divisor such that the synthesizer frequency varies over a third range. The upper limit of the second range falls at the lower limit of the third range. The lower limit of the second range is 85.5 MHz and the upper limit of the third range is 108.0 MHz. By also using a third divisor, a synthesizer signal with a range of 76-108 MHz is generated from the narrow first frequency range.

Abstract: To set one or more events without intermediate scheduling of threads in a multi-threaded system, a scheduler is first rendered essentially ineffective. The events are then set, for example, by repeatedly calling a function to set a single event, once for each event to be set. The scheduler is then restored to its normal effectiveness. The scheduler may be rendered ineffective by artificially setting the priority of the current thread being processed to the highest possible priority level. This prevents the current thread from being preempted by another thread during the time that events are being set. After all events have been set, the priority of the current thread is restored to the original priority level, which then restores the scheduler to its normal effectiveness.
