Abstract
A method for assisting a mobile device to perform positioning measurements on positioning signals periodically transmitted by at least some of a plurality of cells in a wireless communication network includes determining an estimated position of the mobile device and then determining a first set of candidate cells of the plurality of cells based on the estimated position of the mobile device. The method also includes estimating an expected interference of each respective positioning signal that is transmitted by each candidate cell of the first set and selecting a subset of cells from the first set of candidate cells based on the estimated expected interference. Assistance data identifying the selected subset of cells is then generated and sent to the mobile device.
