Abstract: An access terminal that is configured for wireless communication with an access network within a sector is disclosed. The access terminal includes a transmitter for transmitting a reverse traffic channel to the access network, an antenna for receiving signals from the access network, a processor, memory in electronic communication with the processor, and instructions stored in the memory, where the instructions are executable to implement a method. The method includes the steps of (a) determining whether a current power allocation grant (1374) for a flow (1316) on the access terminal has been received from the access network (1304), (b) if the current power allocation grant (1374) is still active, setting a current power allocation (1338a) for the flow (1316) equal to the current power allocation grant (1374), (c) if the current power allocation grant (1374) has not been received, determining the current power allocation (1338a) for the flow (1316), (d) determining an accumulated power allocation for the flow (1316), (e) using the current power allocation (1374) for the flow (1316) and the accumulated power allocation for the flow (1316) to determine total available power (1338) for the flow (1316), and (f) using the total available power for the flow (1316) to determine a power level for a packet that is transmitted to the access network.

Abstract: Metodos y sistemas para estimar y cancelar la interferencia piloto en un sistema de comunicacion inalambrica (por ejemplo CDMA); en un metodo, una senal recibida compuesta de un numero de casos de senal, cada uno incluyendo un piloto, es inicialmente procesada para proveer muestras de datos; cada interferencia piloto del caso de senal puede ser estimada mediante el desensanchamiento. de las muestras de datos con una secuencia de ensanchamiento para el caso de senal, la canalizacion de los datos desensanchados para proveer simbolos piloto, la filtracion de los simbolos piloto para estimar la respuesta de canal del caso de senal, y la multiplicacion de la respuesta de canal estimada con la secuencia de ensanchamiento; los estimados de interferencia piloto a causa de una pluralidad de multiples trayectorias en interferencia se acumulan para derivar la interferencia piloto total, la cual es sustraida de las muestras de datos para proveer muestras de datos de piloto cancelado; estas muestras de datos son procesadas para derivar datos desmodulados para cada una de por lo menos un caso de senal (deseado) en la senal recibida.

Abstract: Aspects of the disclosure relate to wireless communication devices configured to encode information blocks to produce code blocks and interleave the code blocks utilizing an interleaver including a plurality of rows and a plurality of columns, where the number of columns of the interleaver varies between the rows. In some examples, the interleaver includes a right isosceles triangle-shaped matrix of rows and columns. In other examples, the interleaver includes a trapezoid-shaped matrix of rows and columns.
