    摘要: The present invention is a novel and improved method and system for communicating a frame of information according to a discontinuous transmit format. In particular, the present invention describes a method of transmitting eighth rate speech or data frames employing transmit gating and energy scaling which simultaneously reduces the battery usage of a variable rate wireless communication device (50), increases the capacity of the reverse link and provides reliable communication of the eighth rate frames. In the present invention, four methods are presented for transmitting an eighth rate data frame in which half of the frame is gated out and the remaining data is transmitted at nominal transmission energy to accomplish the aforementioned goals.

    摘要: The invention relates to a method and apparatus for data transmission comprising the steps of encoding a first set of data symbols to provide a first set of encoded symbols and a second set of encoded symbols; transmitting the first set of encoded symbols in a first frame; encoding a second set of data symbols to provide a third set of encoded symbols; determining whether the first frame failed to decode; determining a minimum retransmission power level for the second set of encoded symbols if the first frame failed to decode; and transmitting the second set of encoded symbols and the third set of encoded symbols in a second frame if the first frame failed to decode. Efficient transmission of data is achieved by determining a minimum retransmission power level in the event transmitted encoded symbols fail to decode.

    摘要: In a method for negotiating service configuration in a communication system having at least one dedicated channel which is not shared by communication devices in the communication system, a request message indicative of a proposed service configuration is generated in a service negotiator (20). The request message is multiplexed, in a multiplexer (22) coupled to the negotiator (20), with an information data signal to produce a multiplexed signal. The multiplexed signal is encoded in an encoder (24) interposed between the multiplexer (22) and a transmitter (26) in accordance with a service configuration selected by the service negotiator (20). The multiplexed and encoded signal is transmitted by the transmitter (26) over the dedicated channel. Received signals are decoded a decoder (16) interposed between a receiver (14) and a demultiplexer (18). A response message indicative of a response to the proposed service configuration is received by the receiver (14). A determination is made by the service negotiator (20) whether the response message is indicative of a mutually acceptable service configuration. The encoder (24) is directed by the service negotiator (20) to encode the information data signal in accordance with the proposed service configuration if the response message is indicative of an acceptable service configuration. The encoder (24) is directed by the service negotiator (20) to encode the information data signal with a universal default service configuration if the response message is not indicative of an acceptable service configuration.

    摘要: The power control process of the present invention enables a base station communicating over a forward packet channel to a mobile radio to control the power of the mobile radio transmitting over a reverse packet channel to the base station. The base station maintains a maximum energy per bit to total interference spectral density ratio threshold for the reverse channel as well as a desired threshold that results in a low frame error rate. By comparing each radiotelephone's estimated energy per bit to total interference spectral density ratio to the desired and maximum thresholds, power control commands to increase or decrease the radiotelephone's transmit power are generated depending on the outcome of the comparison.
