    Abstract: Un procedimiento para controlar un dispositivo de comunicación inalámbrica, el procedimiento que comprende: transmitir una trama compuesta por una pluralidad fija de subsegmentos, en el que un subsegmento se define como un grupo de control de potencia; recibir un mensaje de confirmación que indica que la trama se ha descodificado con éxito, en el que el mensaje de confirmación se recibe antes de que se complete la transmisión de todos los grupos de control de potencia asignados para la trama, en el que el mensaje de confirmación se recibe en una posición de símbolo de un bit de control de potencia recibido; detener la transmisión de la trama en respuesta al mensaje de confirmación; conmutar por puerta una señal piloto, que responde al mensaje de confirmación, transmitiendo solo la señal piloto para grupos de control de potencia selectos de acuerdo con un patrón de señal piloto de conmutación por puerta que se usa para señalizar la transmisión de una trama a velocidad nula que no contiene bits de tráfico.

    Abstract: A communication satellite system provides for spectral efficient data transmissions by a gateway to multiple user terminals by way of a satellite. The gateway transmits multiple blocks in a single slot, each block intended for one of the user terminals, where each block is encoded and modulated according to a scheme that may be different for each intended user terminal. Upon re-transmission of a block if that block is lost or received in error, the block may be encoded and modulated according to another scheme that is less spectrally efficient than in the first transmission of the block.

    Abstract: Embodiments disclosed herein relate to methods and systems for pilot grouping, route protocols, and scheduling in multi-carrier communication systems. In an embodiment, an access terminal may group a plurality of pilot signals characterized by different frequencies into one or more pilot groups, each pilot grouping being identified by a plurality of parameters (e.g., a PN offset and a group ID). Each pilot group may include pilot signals having substantially the same coverage area. The access terminal may further select a representative pilot signal from each pilot group for pilot strength reporting. The access terminal may also use the pilot grouping for effective set management.

    Abstract: The present aspects relate to methods and apparatuses to power off a modem receiver or components of the receiver at a time prior to the end of the frame based on data in the frame being received and properly decoded before the end of the frame. In an aspect, the apparatuses and methods provide power saving in a wireless device, and include receiving data within a frame at a user equipment, determining whether all payload packet data has been correctly decoded prior to an end of the frame, and powering down a receiver component for a portion of a remainder of the frame in response to determining that all payload packet data has been correctly decoded and where a first time period to a next scheduled overhead bit transmission period of a slot in the frame is greater than a second time period corresponding to a warm-up period for the receiver component.
