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: Embodiments disclosed herein address the need in the art for an extended acknowledgment/rate control channel. In one aspect, an acknowledgment command and a rate control command are combined to form a combined command. In another aspect, the combined command is generated in accordance with a constellation of points, each point corresponding to a pair consisting of a rate control command and an acknowledgment command. In yet another aspect, the points of the constellation are designed to provide the desired probability of error for the respective command pairs. In yet another aspect, a common rate control command is transmitted along with a combined or dedicated rate control command. Various other aspects are also presented. These aspects have the benefit of reduced overhead while providing acknowledgment and rate control to single remote stations and/or groups of remote stations.

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: Un procedimiento para limitar la potencia transmisora pico en un sistema de comunicación de CDMA, comprendiendo el procedimiento las etapas de: transmitir una primera señal (74A) de comunicación con una primera región de alta potencia transmisora, y una primera región de baja potencia transmisora; transmitir una segunda señal (74B) de comunicación con una segunda región de alta potencia transmisora y una segunda región de baja potencia transmisora; y desplazar en el tiempo una entre las señales de comunicación (74A, 74B) primera y segunda, para impedir que ocurran simultáneamente las regiones de alta potencia transmisora primera y segunda, en donde la etapa de desplazamiento en el tiempo está caracterizada por: determinar una pluralidad de desplazamientos temporales para dicha señal entre las señales (74A, 74B) de comunicación primera y segunda; sumar la potencia de las señales (74A, 74B) de comunicación primera y segunda, para determinar una señal de potencia transmisora total en cada unode dicha pluralidad de distintos desplazamientos en el tiempo; seleccionar (106) el desplazamiento en el tiempo correspondiente a la señal de potencia transmisora total con el mínimo nivel máximo; y desplazar en el tiempo dicha señal, entre las señales de comunicación primera y segunda, en dicho desplazamiento (74A, 74B) en el tiempo seleccionado.

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: A method for limiting peak transmit power in a CDMA communication system by transmitting a first communication signal having a first high transmit power region, and transmitting a second communication signal having a second high transmit power region. A first and a second communication signal are time offset to prevent the first and second high transmit power regions from occurring simultaneously. Time shifting only a portion of the first and second communication signals is also taught. The first and second communication signals can also include respective first and second low transmit power regions. The time offset can be selected to align one of the first and second high transmit power regions with one of the first and second low transmit power regions. The total transmit power signal can be determined and the time offset can be selected to minimize a peak level of the total transmit power signal. The communication signals are separated into a plurality of portions and portions of the first and second communication signals are time offset to re-order the sequence of transmission of the plurality of portions.

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: 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.
