Abstract
Methods and apparatus are provided for operating in a first RAN at a working frequency, determining a priority of measurement tasks enabled by the first RAN, and dynamically scheduling the tasks according to the priority. For certain aspects, the first RAN may be a TD-SCDMA network. The measurement tasks are intended to measure at least one parameter of a serving cell in the first RAN on a primary frequency, at least one cell in the first RAN on at least one frequency other than the primary frequency, one or more cells in at least one RAN other than the first RAN (e.g., a GSM network) or any combination thereof. This dynamic assignment allows the UE to make scheduling decisions on which frequencies and RANs to measure, as well as how often these frequencies and RANs are measured, thereby providing for more efficient use of idle slots over conventional haphazard scheduling.
