    Abstract: A method for multicasting a packet begins by providing a buffer for each of two user equipments (UEs) in communication with a base station. A determination is made whether there is a previously unsent packet at the base station. A second determination is made whether both UE buffers are non-empty. A non-empty buffer is flushed if there is no previously unsent packet and if one of the buffers is non-empty. A packet is selected to be transmitted if there is a previously unsent packet or if both buffers are non-empty. The buffers are updated based on feedback received from the UEs.

    Abstract: Un sistema de comunicación incluye un transmisor fijo y un dispositivo de comunicación inalámbrica móvil. El transmisor fijo transmite una señal de fuente definida por un conjunto de caracteres hecho de símbolos. Al menos uno de los símbolos en el conjunto de caracteres se transmite a un nivel de potencia diferente de tal manera que la señal de fuente transmitida aparece con períodos de tiempo de nivel de potencia linealmente independiente. Los períodos de tiempo de nivel de potencia linealmente independiente se utilizan por el dispositivo de comunicación inalámbrica móvil para poblar una matriz de mezclado para procesamiento de separación de señal.

    Abstract: A wireless communication method and system for assigning multi-paths to Rake receiver fingers. A Rake finger assignment database is established in which multi-path signals are categorized into a verified group and an unverified group. Each multi-path is assigned to an individual bin in the database. Eac h bin includes a pilot phase data field, an antenna data field, a code data field, an averaged signal strength data field, an assigned flag data field, a verification flag data field, an update flag data field, an assigned Rake finger number data field and an assignment time counter data field. The mult i- path signals in the verified group are further categorized into an assigned subgroup and an unassigned subgroup. During a measurement interval, each of a plurality of newly measured multi-path signals is compared to the multi-path signals in the database and is processed accordingly.

    IPC: H04B1/02

    Abstract: A communications system includes a fixed transmitter and a mobile wireles s communications device. The fixed transmitter transmits a source signal def ined by a character set made up of symbols. At least one of the symbols in t he character set is transmitted at a different power level so that the trans mitted source signal appears with linearly independent power level time peri ods. The linearly independent power level time periods are used by the mobil e wireless communications device to populate a mixing matrix for signal sepa ration processing.
