Abstract: A system and method to select a modulation coding scheme of a mobile device including establishing a connection between the mobile device and a remote device through a wireless communication network, monitoring at least two measured properties of a radio frequency access link between the mobile device and the wireless communication network, selecting an updated derived C value based on the measured properties of the radio frequency access link, and inducing a change in a modulation coding scheme based on the updated derived C value.

Abstract: 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.
