ABSTRACT:
A method and system for cell identification for uplink interference avoidance that includes a network device and mobile device in a communications network. Inter-frequency measurements are performed by a mobile device on a downlink carrier currently not used by the mobile device. A result of the inter-frequency measurements is compared with another value. Second measurements are initiated on the downlink carrier currently not used by the mobile device based on the comparison. A cell is identified based on the second measurements. The inter-frequency measurements may include receive signal strength indicator (RSSI) measurements, received signal code power (RSCP) measurements, or average channel power-to-total signal power ratio (Ec/Io) measurements. The second measurements may include signal quality measurements.
