METHOD AND APPARATUS FOR CELL IDENTIFICATION FOR UPLINK INTERFERENCE AVOIDANCE USING INTER-FREQUENCY MEASUREMENTS

摘要

A method and system for cell identification for uplink interference avoidance that includes a network device and a mobile device in a communications network. Inter-frequency measurements are performed by a mobile device on a downlink-carrier not currently used by the mobile device (S1). A result of the inter-frequency measurements is compared with another value (S2). Second measurements are initiated on the downlink carrier currently not used by the mobile device based on the comparison (S3). A cell is identified based on the second measurements (S4). The inter-frequency measurements may include received 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.
