User Equipment with Selective Neighbor Cell Detection

摘要

Performing selective tune-away by a user equipment (UE). The UE may include a first radio that is configurable to operate according to a first radio access technology (RAT) and a second RAT. The UE may use the radio to communicate using the first RAT and the second RAT using the first radio. The UE may also perform measurement of a received signal strength for the first RAT. The UE may determine if the received signal strength is less than a threshold. Neighbor cell measurement and/or synchronization may be performed if the received signal strength is less than the threshold. However, if the received signal strength is greater than the threshold, the neighbor cell measurement and/or synchronization may not be performed. The UE may continue to perform page decoding for the first RAT using the first radio, e.g., for each discontinuous reception (DRX) cycle of the first RAT.

1. A method, comprising:
at a user equipment device (UE) comprising a first radio, wherein the first radio is configurable to operate according to a first radio access technology (RAT) and a second RAT:
communicating, using the first radio of the UE, using the first RAT;performing, using the first radio of the UE, a measurement of current channel condition of the second RAT;determining if the current channel condition is less than a threshold;performing, using the first radio of the UE, a neighbor cell synchronization for the second RAT if the current channel condition of the second RAT is less than the threshold, wherein a neighbor cell synchronization is not performed if the current channel condition of the second RAT is not less than the threshold;performing, using the first radio of the UE, a page decode every discontinuous receive (DRX) cycle of the second RAT;communicating, using the first radio of the UE, using the first RAT, after said performing neighbor cell synchronization and the page decode every DRX cycle of the second RAT, wherein during said performing the neighbor cell synchronization and performing the page code, the UE maintains a connection using the first RAT.
