    摘要: In one embodiment the method includes allocating, for a mobile, forward link resources for transmitting data over a shared forward link data channel without allocating reverse link resources for reverse link data transmission in association with the allocated forward link resources. At least a portion of the received data is repeatedly sent to the mobile on the shared forward link data channel over a time division multiple access air interface using the allocated forward link resources until an acknowledgement is received from the mobile or a number of transmissions have taken place.

    摘要: An encoder employs a trellis coded quantization (TCQ) unit and a compression unit. The TCQ uses a set of polynomials that have been selected to maximize granular gain. The TCQ unit operates on a block of samples from a source. The compression unit compresses bit planes of the TCQ output, using parity check matrices of corresponding LDPC codes, to obtain corresponding syndromes. The parity check matrices are selected so their compression performance approaches close to the limit for Slepian-Wolf coding. A decoder employs a decoding unit and an estimation unit. The decoding unit decodes the syndromes using side information to produce an estimate for the TCQ output. The side information is correlated with the source. The estimation unit estimates the block of source samples using the estimated TCQ output and the side information. Trellis coded vector quantization may be used as an alternative to TCQ.

    摘要: A method and an apparatus for maintaining a quality of service (QoS) for a multi-media packet data service in a transport network is provided. The method comprises determining a first packet loss indication for a first flow of QoS traffic packets. The method further comprises determining a second packet loss indication for a second flow of QoS traffic packets, wherein the determination of the first packet loss indication for the first flow of QoS traffic packets is independent from the determination of the second packet loss indication for the second flow of QoS traffic packets. The method further comprises determining whether to drop the first flow of QoS traffic packets based on the first packet loss indication or to drop the second flow of QoS traffic packets based on the second packet loss indication. By using per-flow independent packet loss statistics to determine whether that flow should be dropped and gradually dropping such QoS flows having the most impact on a desired QoS performance, a reduced number of QoS flows may be dropped to recover a data transport network from congestion.

    摘要: An electroluminescent device based on bistability, and method for its use. The device alternates between a low resistance state and a high resistance state by application of an electrical voltage. A bistable electrical device has two electrodes sandwiching an organic material that produces bistable action. An organic light emitting diode next to the bistable device is emits light when conducting. To achieve graduated light output, circuitry is provided for applying to the bistable device a constant bias voltage intermediate a turnoff voltage and a turn-on voltage, and electrical pulses variable in a temporal pulse width or in an additional voltage, or in both. The additional voltage is superimposed on the bias voltage while the pulse is applied. The current through the bistable device, and therefore the brightness of light emitted by the diode after the pulse has ceased, are controlled by varying the pulse width or the additional voltage.

    摘要: The present invention provides a method and an apparatus for controlling transmission power of a wireless unit. The method includes providing a power control in a reverse link to a network that transmits data on a traffic channel in a bursty manner based on a performance metric of a channel with continuous transmission of other data than on the traffic channel. To provide a power control in a reverse link of a spread-spectrum wireless data network a method and an apparatus are provided for combining performance of a quality of service from at least one of a first quality feedback channel and a second quality feedback channel with that of a pilot channel and providing an outer-loop power control in said reverse link for a wireless communication on a traffic channel based on said combined performance of the quality of service to control transmission power of a wireless unit. A quality of service metric may be associated with one or more channels of the reverse link to determine performance of such a channel when transmission of data on a traffic channel is bursty in nature. Using a performance metric, such as a quality of service metric of a pilot channel, a power control in the reverse link may be provided when data is not transmitted on the traffic channel, e.g., in a bursty traffic channel to control transmission power of a wireless unit. In this manner, the transmission power of the wireless unit may be controlled based on an outer-loop power control that provides a continuous control for a non-continuous transmission.

    摘要: A method for gracefully degrading packet data voice quality in a wireless network includes monitoring and evaluating data transfer conditions on the network. This may be done on a network-wide level, or for access terminals individually. For the evaluation, data transfer conditions are compared to criteria that indicate a relative quality level. Based on the evaluation, a variable number of the voice data packets addressed to the access terminals are eliminated prior to transmission over the airlink. If conditions are optimal, no data packets are eliminated. If not, one or more packets may be eliminated periodically (e.g., 1 data packet out of every five) until conditions change. The access terminals compensate for any eliminated packets. In this manner, packet data voice quality is gracefully degraded for temporarily reducing voice traffic on the network when conditions are poor, avoiding the need for dropped calls or the like.
