Abstract:
Disclosed embodiments pertain to the obtaining and utilization of Observed Time Difference of Arrival (OTDOA) assistance data. Cell timing information obtained based on measurements by a Mobile Station (MS) of neighbor cells may comprise cell timing offsets of the neighbor cells relative to a serving cell for the MS. OTDOA assistance data may be generated, where the OTDOA assistance data may comprise an OTDOA assistance data reference cell and a cell timing offset between the serving cell and an OTDOA assistance data reference cell, the reference cell being selected based on the received neighbor cell measurements. Embodiments disclosed also pertain to methods on an MS for performing measurements of neighbor cells comprising cell timing information for neighbor cells by requesting idle periods with a desired length from a base station to perform the measurements, and performing the requested measurements upon receiving confirmation that the idle periods have been configured.
