Abstract: A first method for estimating a location of an MS (MS) in a communication network having a plurality of BTSs (BTSs) includes determining an area in which the MS can communicate with only one of the BTSs. A mean location within the area is calculated and used as the estimate. A second method includes determining an area in which the MS is within an overlapping coverage area of two of the BTSs. A locus of distance points at which a relative time difference of arrival of signals received by the MS from each of the BTSs is constant is determined. A point at which a line having an angle θ based upon relative signal power at the MS between first and second sectors of one of the BTSs intersects the locus is determined, and used as the estimate of the MS location.

Abstract: A system and method are disclosed by which the effects of time of arrival errors may be reduced. In a mobile unit, such as a CDMA device, a correlation pulse is generated when a transmitted code matches a stored reference code. In the absence of multipath effects, correlation pulses are generated in response to the detection of multiple transmissions of the reference code from multiple transmitters. However, multipath effects distort the generated correlation pulses leading to errors in the time of arrival measurements. The present invention calculates the width of the correlation pulses and determines a delay correction factor based on the pulse width. The delay correction factor is added to the measured delay time to provide a more accurate delay time, thus permitting more accurate location measurements based on time of arrival. In alternative embodiments, other signal factors may also be used to apply delay correction factors. The actual location determination may be performed by the mobile unit, or any other positioning determining entity (PDE). The system is also capable of applying correction factors to time of arrival signals received from global positioning system (GPS) satellites.

Abstract: A system and method for bad frame indication of a speech frame includes estimating a signal-to-noise ratio (SNR) and checking a cyclic redundancy code (CRC) value of the speech frame. When the speech frame fails CRC error detection or the SNR is below a pre-specified value, a bad frame indication (BFI) flag is set. When the speech frame passes CRC error detection and the SNR is above the pre-specified value, a receive signal quality metric of the speech frame is checked against a high threshold and, if need be, a low threshold. The BFI flag and the receive signal quality metric for the previous speech frame is checked when the current receive signal quality metric is between the high and low thresholds. The BFI flag is set according to the value of the SNR, the CRC value, the current and previous receive signal quality metrics, and the previous BFI flag.

Abstract: Aspects relate to a UE adapting the capability it advertises based on the network within which the UE is operating. In some examples, if a network currently supports a certain bandwidth, the UE may select the capabilities it will advertise based on that supported bandwidth. In some examples, a UE may acquire information regarding which configurations were considered by a network. In this case, the UE may select the capabilities it will advertise based on such configurations.

Abstract: Techniques are provided for reducing the likelihood of missed pages during cell reselection. For cell reselection with early camping, a terminal determines that reselection from a first base station to a second base station is required (512). The terminal then performs cell reselection and receives sufficient system information to process a paging channel for the second base station (516). The terminal starts monitoring the paging channel upon receiving this information and prior to completing the cell reselection (518). For cell reselection with reconfirmation, the terminal receives and decodes a control channel for the second base station prior to performing cell reselection. For cell reselection with overlapping page reception, the terminal monitors the paging channel for the first base station until a terminating event occurs and starts monitoring the paging channel for the second base station upon receiving sufficient system information. The monitoring of the two paging channels overlaps in time.

Abstract: The velocity of a wireless communications device (WCD) is estimated. In response to this estimated velocity, a tracking speed of a filter is determined that corresponds to the estimated velocity. The filter filters a timing error signal to produce a control signal that controls the timing of a synchronization clock. This synchronization clock may be a finger clock that controls the timing of a pseudonoise (PN) sequence generator configured for despreading a pilot symbol sequence.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may identify a throttling indicator for a shared resource associated with a modem at the UE. The UE may determine a configuration of the modem based on a configuration received from a Radio Resource Control layer of the UE. Based on the modem configuration and the throttling indicator, the UE may identify a throttling level to apply to the modem. The UE may adjust the modem configuration for communicating with a base station based on the throttling level in order to reduce resource usage below a usage threshold. By reducing usage of the shared resource by the modem, the UE may have a greater availability of the shared resource to meet the needs of other components of the UE. This may provide an improved user experience at the UE, among other benefits.

Abstract: To determine the position of a mobile device located within a coverage area of a base station, the time of arrival (TOA) of the CDMA signal received by the mobile device from the base station is reduced in proportion to the received power of the CDMA signal. The mobile device uses the reduced TOA of the CDMA signals together with the received GPS signals to detect its position. Alternatively, the mobile device transmits the TOA and power measurements of the received CDMA signals to a position determination entity (PDE). The PDE biases the TOA to estimate the position of the mobile device and transmits assistance data to the mobile device, thereby enabling the mobile device to receive GPS signals. The received GPS signals alone, or in combination with the biased TOA are then used to recompute the position of the mobile device.

Abstract: To determine the delay between true GPS time and the arrival time of a CDMA signal, a GPS receiver generates a first reference signal that is locked to true GPS time, and applies this signal to a CDMA base station test equipment. The CDMA base station test equipment receives the CDMA signal and generates a second reference signal which has transitions occurring substantially concurrently with transitions of an internal synchronization clock used to sample the first reference signal. The CDMA base station test equipment provides the delay between the second reference signal and the CDMA signal. A frequency/time counter provides the delay between the first reference signal and the second reference signal. The sum of the delays supplied by the CDMA base station test equipment and the frequency/time counter represents the delay between true GPS time and the CDMA signal.

Abstract: A UE apparatus determines UE capability and signals UE capability information to a base station. The UE may signal RF capability information to the base station with reference to at least one band combination and signal other baseband parameter(s) (obp(s)) to the base station. The RF capability information indicate RF capability with reference to at least one other band combination parameter. The obp may be indicated on a per UE basis, a per band basis, a per band combination basis, a per band, per band combination basis; and/or a per CC, per band, per band combination basis. Each band combination may indicate a combination of a numerology, a layer and a bandwidth. In another example, a plurality of basebands may be defined, each baseband indicating a combination of a numerology, a layer and a bandwidth.
