Abstract: A method and apparatus that allows correlations between a selected parameter and the error in a pseudo range measurement to be exploited. A database is established in which the amount of error estimated for particular pseudo range measurements to a beacon is maintained. Clusters are defined. Each cluster is associated with a range of values for the selected parameter. Pseudo range measurements are then associated with a particular cluster based upon the value of the selected parameter at the time (or proximate to the time) the pseudo range masurement was taken. As more estimates of the pseudo range measurements are made, the size of the clusters (i.e., the range of values of the selected parameter) can be reduced. Due to the correlation between the selected parameter and the errors in the pseudo range measurements, reducing the size of the clusters reduces the variance of the error estimates. The mean value of the error estimates is used to correct the error in future pseudo range measurements.

Abstract: A method and system that enables multiplexing a plurality of data streams onto one data stream based on data stream priorities, available transport format combinations (TFCs), and transmission time interval (TTI) constraints of transport frames within the TFCs is disclosed. A subscriber unit (12) has applications that produce separate data streams. Example applications include voice (32), signalling (34), E-mail (36) and web applications (38). The data streams are combined by a multiplexer module (48) into one data stream called the transport stream (50). The transport stream (50) is sent over the reverse link to base station transceivers (BTS) (14). The multiplexer module (48) multiplexes the data streams onto a single stream according to available TFCs, TTI constraints, data stream priorities, and current maximum transmitter power constraints.

Abstract: Un procedimiento para multiplexar corrientes (40, 42, 44) de datos en una corriente (50) de datos, que comprende la recepción de un conjunto de combinaciones de formatos de transporte (TFC); dicho procedimiento caracterizdo: seleccionar una combinación de formatos de transporte para su transmisión desde un conjunto recibido de combinaciones de formatos de transporte, dicha selección se basa en si los formatos de transporte "TF", en la combinación seleccionada de formatos de transporte, tienen cada uno un intervalo de tiempo de transmisión "TTI" que sea menor o igual que una longitud máxima de TTI del tiempo de transmisión actual, el límite del intervalo; en donde la selección de una TFC se basa también en si los TF en la TFC seleccionada coinciden con los TF actuales correspondientes de la última TFC transmitida.

Abstract: Techniques for determining the location of a device based on an initial coarse position estimate for the device, which is derived based on initial (less accurate) estimates of the position of a plurality of transmitters. In one method, the coarse position estimate for the device and revised (more accurate) position estimates for the transmitters are received. A revised position estimate for the device is initialized (e.g., to the coarse position estimate). An update vector is next computed based on the initial and revised position estimates for the device and the initial and revised position estimates for the transmitters. The revised position estimate for the device is then updated based on the update vector. The computation for the update vector and the updating of the revised position estimate for the device can be repeated a number of times to achieve a more and more accurate estimate.
