Abstract: A method is provided for dynamically updating the fractional power control (FPC) parameters of a wireless network such as an LTE network, so that system performance can be improved in a variety of different loading conditions, particularly under conditions of moderate or light loading. An exemplary embodiment includes obtaining a current value of a time-varying uplink interference figure for at least one individual sector s. For at least one such sector s, a value is selected for at least one FPC parameter, thereby to determine a dependency of the target SINR {circumflex over (?)}(k,s) on the path loss ?(k,s) for each UE k in sector s for which {circumflex over (?)}(k,s) falls between a maximum target {circumflex over (?)}max and a minimum target {circumflex over (?)}min. The selecting step is responsive to the obtained interference figure, such that at least one FPC parameter.

Abstract: Inter-frequency handoffs in a CDMA or other wireless communication system are controlled using a noise-limited coverage trigger metric which is able to distinguish between same-frequency cell boundaries and other-frequency cell boundaries in the system. The trigger metric may be generated as a function of an average signal-to-noise measure for pilot signals received at a mobile station of the system and a linear sum of the signal-to-noise measures. The signal-to-noise measures may be generated in the mobile station and included in messages transmitted from the mobile station to one or more base stations of the system. The trigger metric is used to control a handoff from a current frequency to a new frequency in an ongoing call. The trigger metric may alternatively be based on a measure of mobile receive power alone.

Abstract: A method and system that minimizes pilot signal overlap and radio frequency (“RF”) interference by estimating changes in pilot coverage for different traffic channel loading and power conditions. Once base stations are positioned, a terminal for measuring received pilot signal strengths, such as a mobile station or pilot scanner, is used to collect and generate the baseline pilot survey data, which is then stored on a disk or tape. Base station transmit pilot EC/IOs, i.e., traffic channel loads on forward links, are also stored on disk or tape. The invention uses two adjustment factors associated with transmit power and traffic channel loading to optimize for different RF conditions, specifically for different base station transmit power or forward link loading conditions. For each RF condition, the methodology calculates the changes in the baseline pilot survey data. This reflects what EC/IOs a mobile station would receive under the given conditions.
