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: A user equipment (“UE”) that performs methods to connect to multiple radio access networks (RAN) including a home network RANs and roaming RANs to perform communications. An exemplary method performed by a UE initially connected to a Long Term Evolution radio access network (LTE-RAN) of a home network and registered with a voice over LTE (VoLTE) service of the home network to perform voice communications via the LTE-RAN, includes detecting a service disrupting event preventing VoLTE communication with the LTE-RAN, deregistering from the VoLTE service of the home network, scanning for available bands in the LTE-RAN of the home network and while scanning for the available bands in the LTE-RAN of the home network, connecting to a further radio access network (RAN) of the home network that allows circuit-switched communications with the home network, wherein the UE performs voice communications as circuit-switched communications via the further RAN.

Abstract: Instead of barring an LTE network for the Long Bar Time duration (LBT) if the LTE cell doesn't support CSFB, a wireless communication device may perform a scan for LTE networks before expiration of the LBT if the UE has changed its location. When the UE is in LTE acquisition mode, or the necessary information about a CS network for CSFB is unavailable, the UE may maintain its state on both the LTE and CS network, and check CS paging messages to see if the UE can decode any status. Unlike for CSFB, checking for overhead messages may be performed over the LTE system, and the UE may wake up on CS pages to determine if a suitable network is available. By maintaining its state on both types of networks, the UE may use LTE for data services which would otherwise be provided by different systems for the CS networks when messages transmitted over LTE do not include CS registration information.

Abstract translation: 如果LTE小区不支持CSFB，则不是将LTE网络限制在长时间段时间长度（LBT），如果UE改变了其位置，则无线通信设备可以在LBT到期之前对LTE网络执行扫描。 当UE处于LTE获取模式时，或者关于CSFB的CS网络的必要信息不可用时，UE可以在LTE和CS网络上保持其状态，并检查CS寻呼消息以查看UE是否可以解码任何状态 。 与CSFB不同，可以通过LTE系统执行开销消息的检查，并且UE可以在CS页面上唤醒以确定合适的网络是否可用。 通过在两种类型的网络上维持其状态，当LTE发送的消息不包括CS注册信息时，UE可以使用LTE用于数据业务，否则这些数据业务将由CS网络的不同系统提供。

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: A method for transitioning a video call is provided. The method can include a wireless communication device participating in a video call with a remote communication device via a first video call session established over a connection between the wireless communication device and a first cellular network. The video call can include a packet switched video stream carried over a first bearer and an audio stream carried over a second bearer. The method can further include the wireless communication device determining a degradation in a connection quality for the first cellular network; transitioning to a legacy cellular network having a circuit switched domain in response to the degradation in connection quality for the first cellular network; establishing a second video call session on the legacy cellular network; and using the second video call session to continue the video call on the legacy cellular network.
