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: 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.

Abstract: One embodiment described herein takes the form of a user equipment (UE). The UE includes a transceiver and a processor. The processor is configured to associate with a secondary UE for collaborative transmission of a data payload of one of the UE or the secondary UE to a base station. The processor is configured to determine a link quality with the base station or the secondary UE, and determine a location of the UE or the secondary UE while associated with the secondary UE. The processor is configured to transmit to the base station or the secondary UE at least the determined link quality or the determined location, and determine to maintain, re-establish, or disable the association with the secondary UE based on at least one of a number of factors including: the determined link quality, the determined location, or an indication received from the base station.

Abstract: A user equipment (UE) is configured to join a standalone non-public network (SNPN). The receives SNPN information from one or more broadcast messages transmitted from a base station serving as an onboarding base station for the SNPN, determines whether the onboarding base station may be used for onboarding by the UE based on the SNPN information and UE SNPN information stored at the UE and onboards the UE to the SNPN when it is determined that the onboarding base station may be used for onboarding by the UE.

Abstract: A user equipment (UE) may operate on a dormant bandwidth part (BWP) and a non-dormant BWP of a carrier. The UE identifies a dormant bandwidth part (BWP) and a non-dormant BWP of a carrier corresponding to a primary secondary cell (PSCell) of a secondary cell group (SCG) for dual connectivity (DC), determines that the dormant BWP is configured in an active state and performing one or more actions corresponding to the dormant BWP.
