  • Patent number: 8027690
    Abstract: Methods and apparatus for sensing the presence of a transmission signal type within a wireless channel in a wireless communication system, such as those including the use of wireless microphones, are described. Sensing the transmission signal type includes calculating a spectral density estimate of a signal on the wireless channel. A first test value, derived from the calculated spectral density estimate, is compared to a first threshold. A preliminary determination of the presence of the transmission signal type is made if the first test value exceeds the first threshold. Sensing the presence of the signal type after preliminary determination of the presence of the signal type is made by determining that an observed spectral density of a prescribed signal added to the signal on the wireless channel matches a model estimate of the spectral density of the prescribed signal to a sufficient degree.

  • Patent number: 8014280
    Abstract: Techniques for performing admission control based on quality-of-service (QoS) performance in a wireless communication network are described. QoS performance (e.g., delay or throughput performance) of admitted data flows may be determined. Whether to admit or reject a new data flow may then be determined based on the QoS performance of the admitted data flows. The admitted and new data flows may have delay bounds. The QoS performance of the admitted data flows may be given by a measured sector delay, which may be determined based on actual delays of packets. A measured flow delay for each admitted data flow may be determined based on delays of packets for that flow. The measured sector delay may then be determined based on the measured flow delays for all admitted data flows. The new data flow may be admitted if the measured sector delay is less than a delay threshold.

  • Patent number: 7769079
    Abstract: In a code division multiple access communication system (100), a method and an accompanying apparatus provide for an efficient control of a gain level of a communication channel at various mobility levels. A rate of change of a carrier to interference ratio (C/I) of a communication channel received at a receiver (400) is determined. The gain level of the communication channel may be based on the rate of change of the C/I of the communication channel. A mobility level of the communication channel may be compared to a low mobility threshold corresponding to a low mobility level. If the mobility level meets the low mobility threshold, the gain level of the communication channel may be based on the rate of change of the C/I of the communication channel.

  • Patent number: 7733792
    Abstract: A method and apparatus for dynamically adjusting the signal-to-interference ratio (SIR) threshold used to control signal transmission power in closed loop communication systems. The closed loop power control comprises an inner loop that provides up/down transmission power control commands to a transmitter based upon a comparison of the SIR for a received signal to the threshold SIR. The outer loop dynamically adjusts the threshold SIR using historic inner loop power control information. When it is detected that the inner loop is not acceptably performing power control, the target SIR is not changed, or may increased or decreased more or less than 0.5 dB or 0.5 dB/99, respectively.

  • Patent number: 7653028
    Abstract: Multiple access interference may be substantially removed by introducing a near-far situation in which a near mobile and a far mobile (“near” and “far” based on signal strength) are selected, resources allocated among these and other mobiles, and the data is packetized for transmission during a transmission interval such that the data intended for the far mobile is transmitted along with the data intended for the near mobile. Forward link signals are then appropriately scheduled. Signals intended for the far mobile and the near mobile are decoded from the composite signal received at the near mobile. The signal intended for the far mobile is then removed from the composite signal received at the near mobile.

  • Patent number: 7630731
    Abstract: An apparatus, system, and method efficiently manage reverse link resources by allowing a mobile station to select between transmitting a payload at 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.
