Methods and apparatus for power saving in discontinuous reception—adaptive neighbor cell search duration

摘要

Methods and apparatus for adaptively adjusting temporal parameters (e.g., neighbor cell search durations). In one embodiment, neighbor cell search durations during discontinuous reception are based on a physical channel metric indicating signal strength and quality (e.g. Reference Signal Received Power (RSRP), Received Signal Strength Indication (RSSI), Reference Signal Receive Quality (RSRQ), etc.) of a cell. In a second embodiment, neighbor cell search durations are based on a multitude of physical layer metrics from one or more cells. In one variant, the multitude of physical layer metrics may include signal strength and quality metrics from the serving base station as well as signal strength and quality indicators from neighbor cells derived from the cells respective synchronization sequences.

1. A mobile device configured to operate in a discontinuous reception mode, the mobile device comprising:
a processor; at least one wireless interface in data communication with the processor; logic in data communication with the processor and the at least one wireless interface, the logic configured to:
obtain a plurality of physical layer metrics of a serving base station and of one or more neighbor cells;compare a first metric of the obtained plurality of physical layer metrics against a current first and second thresholds of a plurality of respective first and second sets of thresholds of the plurality of neighbor cell search parameters; andin response to determining that the first metric is outside of the first and second thresholds, update the current first and second thresholds to new first and second thresholds of the plurality of first and second sets of thresholds and adjust a neighbor cell search duration parameter to a value corresponding to the new first and second thresholds.
