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: Embodiments described herein relate to an apparatus, system, and method for providing aperiodic uplink grants to a UE for aperiodic communications from the UE to a base station. In some embodiments, the UE may be configured to communicate information to the base station, which may be useable by the base station to determine an uplink grant schedule for subsequent communications between the base station and the UE. This uplink grant schedule may be aperiodic, i.e., the uplink grants may be issued at non-uniform intervals of time. The UE may receive the uplink grants from the base station according to the uplink grant schedule. The UE may transmit uplink communications to the base station in response to the received uplink grants.

Abstract: QoS based uplink data buffering while TTI bundling is enabled by a wireless user equipment (UE) device. The UE may establish a packet-switched connection with a network via a wireless link. The UE may receive, at a media access control (MAC) layer, an indication to enable TTI bundling. The UE may selectively buffer uplink data at an application layer based on the indication to enable TTI bundling. The uplink data may be buffered selectively based on Quality of Service (QoS) considerations. Uplink transmissions may subsequently be performed using TTI bundling.

Abstract: Techniques are disclosed relating to informing a network that a UE desires packet-switched voice communication. In some embodiments, the information transmitted to the network distinguishes between voice communications and other communications (e.g., other IMS communications) and is transmitted prior to establishment of a dedicated bearer for IP multimedia subsystem (IMS) signaling for the apparatus.
