Abstract
A method using multiple receivers of a wireless communication device to accelerate cell selection and reselection is disclosed. Multiple receivers of the wireless device are used to implement carrier aggregation in LTE connected mode. The multiple receivers of the wireless device are used to search for cells concurrently across multiple radio frequency bands and/or multiple radio access technologies during cell selection and/or cell reselection procedures. A first receiver and a second receiver of the wireless device each search for cells over different radio frequency bands simultaneously, and accordingly the cell selection and reselection time is effectively reduced compared to using only one receiver. Multiple receivers are also used concurrently, in parallel, to accelerate inter-frequency cell detection and measurement and for inter-RAT searches and measurements.
