    • The present invention relates to methods and arrangements to estimate neighbor cell interference for admission control purposes. Information on at least the total estimated neighbor cell interference power and the own cell power for frequency subsets of tones ft is signalled to neighboring cells for calculating a vector of impact values describing the interference impact of transmissions in a first impacting cell on respective impacted neighbor cells. The neighbor cell interference impact caused by a resource allocation in a first cell is estimated by help of the pre-calculated impact values such that resources are allocated to cause a minimized interference impact on said neighboring cells.

    • Positioning and location services are provided in a wireless communication network using civic address information. The civic address information may comprise a data structure including textual Information Elements such as apartment or office number, street number, street name, city, state, postal code, and the like. A positioning method is defined comprising performing a civic address lookup to obtain a location in civic address format for an identified node, based upon information about the identified node's serving (or associated) node and neighbor nodes. Signaling is defined to request the civic address positioning method, to exchange capabilities, to communicate location information using a civic address format, report a positioning failure and optionally the failure cause, and the like. Location information may be translated between a civic address format and a 3GPP or 3GPP2 positioning format. The positioning method and associated signaling are particularly advantageous in indoor environments, where conventional positioning methods fare poorly or fail altogether.
