Mobility enhancement for fast moving user equipment in a heterogenous network environment

摘要

Relative sizes of neighbor cells are identified, and measurement reporting of the neighbor cells is differentiated in dependence on at least the relative size. In one embodiment the relative sizes are identified by a frequency layer and/or physical cell identity sent by a serving cell. The differentiated reporting may be implemented by using different values, based on the relative sizes, of a measurement or reporting parameter or a scaling factor (such as T_reselection or time to trigger) which adjusts either of those parameters. In one embodiment the differentiated measurement reporting is conditional on a user equipment which sends the measurement reports being classified as fast moving, and in another is further conditional on it also having no active data transfer applications ongoing. In various embodiments, detecting and measuring of small neighbor cells (and thus their reporting) is omitted, or measurements can be collected normally and only the reporting is omitted.
