Abstract: Methods that are performed by a user equipment (UE) and corresponding methods of base stations that allow a UE to determine whether the UE is in a carrier aggregation enabled or disabled state. One exemplary embodiment of a method performed by a UE determines a first artificial value for a first parameter and a second artificial value for a power headroom (PHR) for a secondary component carrier (SCC), the first and second artificial values being substantially low relative to a configuration of the network, generates an artificial report including the first and second artificial values, transmits the artificial report to a primary cell providing a primary component carrier (PCC) and receives an indication that the UE is placed in a carrier aggregation disabled state.

Abstract: Described herein are systems and methods for prioritizing frequency selection of a user equipment (“UE”) having a transceiver configured to enable the UE to establish a connection with a network using at least two communication protocols. A method may comprise recording, at the UE, a camped frequency and a camped band with which the UE is communicating with the first network in the first protocol, disconnecting from the first network and connecting to the second network, and disconnecting from the second network and reconnecting to the first network, wherein the reconnecting to the first network includes determining whether one of the camped frequency or a different frequency within the camped band is available for reconnection to the first network, and reconnecting to the first network using the one of the camped frequency or the different frequency within the camped band.

Abstract: Method and apparatus to trigger a handover of a mobile device from a serving cell to a neighbor cell based on signal quality are disclosed. The mobile device measures signal strength and signal quality for the serving cell. When the signal strength exceeds a network-defined threshold and the signal quality falls below a mobile device defined threshold, the mobile device measures at least one neighbor cell. When a neighbor cell exceeds the network-defined threshold for signal strength and also meets the mobile device defined signal quality threshold, the mobile device sends a measurement report to the serving cell to trigger the handover. The measurement report includes modified values that indicate the serving cell does not meet network-defined threshold values and that the neighbor cell outperforms the serving cell.
