Abstract: Un aparato para proveer canales para senales piloto auxiliares ortogonales en una disposicion de comunicacion celular. Las transmisiones pueden hacerse ortogonales usando pilotos auxiliares ortogonales y canales de tráfico Walsh diferentes en áreas adyacentes. De acuerdo con el patron IS-95, la senal piloto es cubierta con el cero secuencial Walsh de 64 partes. La secuencia Walsh de todos ceros de 64 partes puede designarse como M. Las senales piloto adicionales pueden proveerse concatenando secuencias P todos ceros de 64 partes y M todos unos. De este modo, para dos senales piloto pueden usarse las secuencias Walsh piloto de PP y PM. Para cuatro senales piloto, pueden usarse las secuencias Walsh piloto de PPPP, PMPM, PPMM y PMMP. Puede generarse cualquier numero de secuencias Walsh piloto que se necesite, sustituyendo cada bitio en una secuencia Walsh de bitio K por la secuencia P todos ceros, o la secuencia M todos unos, de 64 partes, segun el valor de cada bitio. Un aparato para recibir dichas senales piloto, un aparato para proporcionar transmisiones particularizadas ortogonales mediante dichas senales y un aparato para proporcionar un rendimiento mejorado en estas ultimas.

Abstract: Method and apparatus for providing link quality feedback to a transmitter (32,34). The method comprises: measuring link quality of a received signal; generating a quality message during a quality message period, the quality message representative of a link quality at a first period; generating one or more differential indicators during the quality message period, the differential indicators representative of a change in link quality following the first period.

Abstract: A method and apparatus for wireless communications wherein a base station transmits a signal to sending data to a subscriber station through a signal beam that sweeps through the coverage area of the base station. User data addressed to the subscriber station is buffered until the signal beam angle of the signal beam allows efficient transmission. The base station may alter the beam sweep speed or the shape of the beam's radiation pattern over time to maximize system efficiency and capacity.

Abstract: A transmitting entity uses different steering vectors for different subbands to achieve steering diversity. Each steering vector defines or forms a beam for an associated subband. Any steering vector may be used for steering diversity. The steering vectors may be defined such that the beams vary in a continuous instead of abrupt manner across the subbands. This may be achieved by applying continuously changing phase shifts across the subbands for each transmit antenna. As an example, the phase shifts may change in a linear manner across the subbands for each transmit antenna, and each antenna may be associated with a different phase slope. The application of linearly changing phase shifts to modulation symbols in the frequency domain may be achieved by either delaying or circularly shifting the corresponding time-domain samples.

Abstract: A time-varying transformation is used to correlate the magnitude of the interference between multiple antenna paths. Embodiments incorporating the time-varying transformations provide transmit diversity gains to remote stations that are not configured for transmit diversity reception. In addition, some of the embodiments can be further configured to balance the load between multiple power amplifiers.

Abstract: Systems and techniques are disclosed relating to communications. The systems and techniques involve transmitting a signal over a plurality of time periods, receiving a plurality of parameters each relating to the signal transmission during a different one of the time periods, filtering a first one of the parameters to generate a first filtered parameter, filtering a second one of the parameters as a function of the first filtered parameter to generate a second filtered parameter, and adjusting the signal as a function of the second filtered parameter.

Abstract: In a wireless communication system (50) a method for combination transmission of packet data and low delay data. In one embodiment a parallel signaling channel provides a message to receivers (56, 58, 60) indicating a target recipient of packet data. The message also identifies the transmission channel used for packet data transmissions. Each receiver may then selectively decode only packets where the message identifies the receiver as a target recipient. The data packets stored in a buffer are ignored if the target recipient is another mobile unit. In one embodiment, the message is sent concurrently with the data packet on a parallel channel. In one embodiment, the message is punctured into the high rate packet data transmission.
