Abstract: In accordance with an exemplary embodiment of the invention, an apparatus, system, and method efficiently manage reverse link resources by allowing a mobile station to select between transmitting a payload a standard power level and transmitting a smaller payload at a boosted power level. The mobile station, therefore, can autonomously select a QoS (Quality of Service) level for physical layer packets. Based on reverse link transmission information received from a base station, the mobile station derives a reverse link transmission guideline defining the power levels and associated payloads for at least a standard service and boosted service. The mobile station selects a reverse link transmission power level from a plurality of power levels including at least a standard reverse link transmission power level associated with a standard payload size and a boosted reverse link transmission power level associated with a boosted payload size where the standard payload size is greater than the boosted payload size.

Abstract: Una entidad transmisora utilizas diferentes vectores de direccion para diferentes sub-bandas a fin de lograr la diversidad de direccion; cada vector de direccion define o forma un haz para una sub-banda asociada; se puede utilizar cualquier vector de direccion para la diversidad de direccion; los vectores de direccion se pueden definir de manera que los haces varien en una forma continua en lugar de una forma abrupta a traves de las sub-bandas para cada antena de transmision; como un ejemplo, los desplazamientos de fase se pueden cambiar en una forma lineal a traves de las sub-bandas para cada antena de transmision, y cada antena se puede asociar con una inclinacion de fase diferente; la aplicacion de desplazamientos de fase linealmente cambiantes para simbolos de modulacion en el dominio de frecuencia se puede lograr retrasando o desplazando circularmente las muestras de dominio de tiempo correspondientes.

Abstract: Methods and apparatus are presented for efficient broadcasting in wireless packet data systems. A single MAC_ID is used for broadcasting to a group of subscribers. By using the channel quality information of the group of subscribers, a base station determines the identity of the subscriber with the worst channel conditions. The timing and the transmission format of the multi-cast are then tailored so that the subscriber with the worst channel conditions is capable of recovering the transmission. If the timing and the transmission format is chosen in relation to subscriber with the worst channel conditions, it is probable that other subscribers will be able to recover the transmission as well. Hence, only a single MAC_ID need to be used to make a single broadcast, rather than sending multiple transmissions to multiple subscribers.

Abstract: Power control of mixed voice and data transmissions is disclosed. A voice signal is transmitted at a dynamically-adjusted voice transmit power capped at a maximum voice transmit power limit. Concurrently, data bursts are transmitted on top of the voice signal. Data noise is inserted between the data bursts transmissions. The data burst and inserted data noise are transmitted at a dynamically-adjusted data transmit power based on the voice transmit power to restrict the rate of change of the data transmit power until a maximum data transmit power limit is reached.

Abstract: An efficient use of communication resources is provided by determining a behavior for selecting the payload size (data rate) of a reverse link transmission from a mobile station to a base station. The mobile station may store a predetermined table including the ratio of the power levels of the traffic channel and pilot channel (TPR), where each entry corresponds to one or more specific sizes of data payload, and consequently a data rate for transmission in a predetermined time frame. The payload size is selected based on an authorized-TPR. The authorized-TPR and a target-TPR are adjusted in accordance with a value of common TPR commands received from the base station. A fast-ramp-up behavior for adjustments of the authorized-TPR is followed when the authorized-TPR is less than the target-TPR. The down TPR commands are ignored in the adjustments of the authorized-TPR to allow following a fast-ramp-up behavior.

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 provides for efficient data rate control and power control processes by transmitting a primary and a secondary pilot channel associated with a data channel in the reverse (uplink) link. The primary and secondary pilot channels are used for decoding the data. A ratio of power levels of the primary and secondary pilot channels is based on at least one of the data rate and payload size of the data channel. It is determined whether the transmission of the primary pilot channel and the secondary pilot channel associated with the data channel is necessary based on comparing one of the data rate and the payload size of the channel in the reverse link to a predetermined value. The power level of the primary pilot channel is maintained independent of at least one of data rate and payload size of the data channel. The power level of the secondary pilot channel may be adjusted based on at least one of data rate and payload size of the data channel.
