Abstract: A method and apparatus for arranging various types of data, and at various rates, into a uniquely structured format for transmission. Data for transmission formatting may be speech data provided by vocoder (14) or different types of secondary traffic. The data organized into frames of a predetermined time duration for transmission by a microprocessor (18). The data frames are organized, depending on the data, to be at one of several data rates. Vocoder data is provided by vocoder (14) at one of several data rates and is organized in the frame according to a predetermined format. Frames may be formatted with a sharing of vocoder data with non-vocoder data to be at a highest frame data rate. Different types of non-vocoder data may be organized so as to also be at the highest frame data rate. Additional control data may be provided within the data frames to support various aspects of the transmission and recovery upon reception.

Abstract: En resumen, de acuerdo con una modalidad, se proporciona un método para transmitir señales. Las formas de onda de señales se transmiten desde al menos dos sectores respectivos. Al menos dos sectores respectivos provienen de al menos dos conjuntos diferentes de un súperconjunto de sectores. Las formas de onda de señal transmitidas incluyen formas de onda de señal al menos prácticamente ortogonales mutuamente al menos a lo largo de una dimensión de señal particular. Una ventaja de tal modalidad, por ejemplo, es la interferencia de señal reducida.

Abstract: In a data communication system capable of variable rate transmission, high rate packet data transmission improves utilization of the forward link and decreases the transmission delay. Data transmission on the forward link is time multiplexed and the base station transmits at the highest data rate supported by the forward link at each time slot to one mobile station. The data rate is determined by the largest C/I measurement of the forward link signals as measured at the mobile station. Upon determination of a data packet received in error, the mobile station transmits a NACK message back to the base station. The NACK message results in retransmission of the data packet received in error. The data packets can be transmitted out of sequence by the use of sequence number to identify each data unit within the data packets.
