Abstract
The disclosed technology is directed towards switching the primary cell in a carrier aggregation scenario to improve performance. Measurement data of a mobile device (user equipment) is evaluated with respect to one or more various criteria such as cell carrier bandwidth, cell carrier load, cell-related capability and other carrier data (e.g., dynamic spectrum sharing versus clean, time division duplex or frequency division duplex), and others. Device conditions such as overheating can be considered as well. The evaluation results in a ranking of primary cell candidates. If a more optimal primary cell (candidate) is available, the primary cell in the carrier aggregation combination is switched to the candidate that is ranked the highest. Switching can be relatively very fast, such as based on already existing layer-1 (L1) and/or layer-2 (L2) measurement data. Layer-3 (L3) measurement data also can be obtained on demand, for example, to use in the evaluation.
