  • Patent number: 6650904
    Abstract: Methods for optimizing an uplink power window associated with a radio receiver, wherein the uplink power window is defined by upper (PU) and lower (PL) power levels. In an exemplary embodiment, the method includes the steps of: i) determining a carrier signal strength (C) and an interference level (I); ii) calculating a carrier-to-interference ratio (C/I); iii) comparing the carrier-to-interference ratio (C/I) to a predefined target value; and iv) if the carrier-to-interference ratio (C/I) is less than the predefined target value, increasing the size of the uplink power window, otherwise, if the carrier-to-interference ratio (C/I) is greater than the predefined target value, decreasing the size of the uplink power window. By using the methods of the present invention, the uplink power window of a radio receiver can be dynamically-adapted to effectively minimize uplink interference while maintaining satisfactory quality of service.

  • Patent number: 6507742
    Abstract: A method of automatically adaptively assigning color codes to radio channels in the wireless network. The method comprises the steps of assigning an initial color code to a channel using a propagation prediction technique and automatically optimizing the initial color code assignment of the channel using radio disturbance measurement data when an alternate color code with the least amount of disturbance is identified.

  • Patent number: 6295279
    Abstract: A telecommunications system and method is disclosed for obtaining an accurate reverse-link Carrier-to-Interference (C/I) measurement for a Time Division Multiple Access (TDMA)-based system in a field environment. The field measurement is performed by using one time slot (voice channel) of one TDMA carrier for recording the carrier signal strength while two other time slots (two idle voice channels) are used in recording the co-channel or adjacent channel interference in a pseudo real time basis. Either the maximum interference or the average interference on the two additional time slots can be used to determine the C/I performance. Alternatively, only one additional time slot can be used to measure the interference. For example, if one of the additional time slots is busy, the interference can be measured on the other one of the additional time slots.
