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.

Abstract: A communication method and system are provided that include providing synchronization information about a co-sited downlink carrier. This information may be transmitted to from a base station to a mobile device. The mobile device may receive this information and perform handover or measurements based on the received synchronization information.

Abstract: A communications method and apparatus are provided for estimating signal quality (Ec/IO) for uplink interference avoidance. This may involve measuring a signal strength of a carrier and estimating a value of RSCP. A signal quality estimate may be determined based on the measured signal strength and the estimated value of RSCP. Further operations (such as handovers) may be performed based on the estimated signal quality.

Abstract: A method and apparatus for selection of downlink carriers in a cellular system that includes selecting a first downlink carrier for use by a mobile node. A decision is made that the mobile node should use another downlink carrier. The mobile node is then directed by a network node to use a second downlink carrier. The first downlink carrier and second downlink carrier may be from different cells or the same cell supplying downlink frequencies. The network node may decide that the mobile node should use another downlink carrier based on several factors such as current load conditions of the cells supplying the first downlink carrier and the second downlink carrier, a type of service on the current downlink carrier, whether the mobile node has connection capability at frequencies of the second downlink carrier, or if a potential interference condition may exist.

Abstract: The indication given by SSDT in soft handover as to whether a cell is primary or not is used by base stations whether or not the base stations actually use it to configure DSCH transmission power with the principle that if the cell is primary, DSCH power is set based on DCH and, if not then a fixed power level or an offset with respect to DCH is used.
