    Abstract: Techniques for efficient data transmission and reception in a wireless communication system are described. In an aspect, a Node B sends transmissions on a shared data channel to a user equipment (UE) based on at least one parameter assigned to the UE prior to the transmissions. The Node B sends no signaling for the transmissions sent to the UE on the shared data channel. The UE processes the transmissions received from the shared data channel based on the assigned parameter(s). In another aspect, a Node B may send transmissions to a UE in time intervals assigned to the UE. In yet another aspect, a Node B may send transmissions to a UE based on assigned or non-assigned parameters. The Node B sends signaling whenever transmissions are sent with non-assigned parameters. The UE may process a transmission based on parameters obtained from received signaling or the assigned parameters. Figure 10

    Abstract: Method and apparatus for providing link quality feedback to a transmitter (32,34). In one embodiment, a periodic link quality message is transmitted on a gated channel, while continuous differential indicators are transmitted. Between quality messages, the differential indicators track the quality of the link. In one embodiment, a remote station includes a differential analyzer (212) to determine the change in successive channel quality measurements. The quality metric and the differential indicator are used for providing power control commands and rate control commands to teh base station. The quality metric and the differential indicator are transmitted at two different frequencies.

    Abstract: Techniques for performing duplicate detection and re-ordering for a HARQ transmission are described. For duplicate detection, a receiver determines whether a decoded packet x for an ARQ channel y is a duplicate packet based on packet x and a prior decoded packet for ARQ channel y. For re-ordering, the receiver determines whether an earlier packet is still pending on any other ARQ channel based on prior decoded packets for the ARQ channels and forwards packet x only if there are no pending earlier packets. There are no pending earlier packets on another ARQ channel z if (1) a decoded packet was received on ARQ channel z at a designated time or later or (2) a decoded packet was not received on ARQ channel z within a time window from current time.

    Abstract: A method and apparatus for controlling transmit power levels of a plurality of different data streams (120, 120a, 122, 122a, 124, 124a) transmitted from at least one base station to a mobile station in a mobile radio communication system. The first and second data streams are trasmitted from the base station and received at the mobile station. A stream of power control commands is formed at the mobile station in accordance with either the first or second received data stream. A power control signal is formed at the mobile station from the first stream of power control commands and transmitted to the base station. A received stream of power control commands is formed from the received power control signal at the base station, and the transmit power levels of the first and second data streams from the base station are controlled in accordance with the received stream of power control commands.

    Abstract: Aparato utilizado para ajustar un objetivo de relación de señal a interferencia de un sistema de control de potencia de bucle cerrado usado en una red de comunicaciones inalámbricas, teniendo el citado sistema de control de potencia de bucle cerrado un bucle interior y un bucle exterior, que comprende: un medio de bucle interior (612, 614, 616) para dar instrucciones a un transmisor (506) para incrementar la potencia de transmisión enviando al transmisor una orden de aumento de potencia cuando una relación de señal a interferencia estimada de una señal recibida desde el transmisor está por debajo del objetivo; y medios de bucle exterior (618) para ajustar el objetivo cuando una tasa de transmisión de error de la señal recibido sobrepasa una tasa de transmisión de error predeterminada; caracterizado porque el aparato comprende, además, medios para inhibir el ajuste del objetivo cuando se indica por la información de control de potencia de bucle interior.
