Abstract
Systems and methodologies are described herein that facilitate reduced complexity network-assisted device positioning in a wireless communication system. As described herein, a mobile device and/or other suitable device can utilize positioning assistance messages received from a location server, a serving network cell, and/or other entities, to assist in position fixing based on reference signals (e.g., positioning reference signals (PRSs)) detected from nearby network cells. Positioning assistance messages as described herein can include, for example, information relating to PRS bandwidths, transmit antenna configurations, and/or other parameters of respective cells from which reference signals are detected by a device during positioning. As further described herein, messaging load can be reduced by providing bandwidth and/or antenna configuration information relative to a given reference cell, such that parameters of non-reference cells that are equivalent to corresponding parameters of the reference cell can be omitted from transmitted positioning assistance data.
