Abstract: Methods, apparatuses and computer readable media are described that adjust connection states between a mobile wireless device and a wireless network upon detection of a connection state synchronization failure. After an interruption of a connection between the mobile wireless device and the wireless network, the mobile wireless device responds to a paging message received from the wireless network to establish a new radio resource control (RRC) connection or to re-establish an RRC connection with the wireless network, when an internal state of the mobile wireless device an at least a portion of contents of the paging message indicate the connection state synchronization failure.

Abstract: Apparatuses, systems, and methods for a user equipment device (UE) to perform methods for EPS fallback when initiating a voice call while camped on a 5G cell. The UE may camp on a 5G network by performing an IMS registration procedure/IMS SIP invite procedure with an IMS. The UE may initiate a voice call and determine that the voice call cannot be established over the 5G NR network. In response, the UE may perform a TAU procedure or an attachment procedure with a cell of a 4G network. The IMS may be transferred to the 4G network during TAU/attachment procedure. The UE may, in response to determining that it is barred from the 4G network, transition back to the 5G network and transmit, to the 5G NR network, a SIP cancel request to allow a context associated with the UE to be cleared from the IMS.

Abstract: This disclosure relates to techniques for providing paging for a remote wireless device to a relay wireless device in a wireless communication system. A cellular base station may receive an indication from a relay wireless device of a relay link between the relay wireless device and a remote wireless device. The cellular base station may provide paging information for the remote wireless device to the relay wireless device based at least in part on the indication of the relay link between the relay wireless device and the remote wireless device.

Abstract: This disclosure relates to methods and devices for mitigating overheating in a user equipment device (UE). The UE is configured to communicate over each of LTE and 5G NR and may be configured to communicate through 5G NR over each of a Sub-6 GHz and a millimeter Wave (mmW) frequency band. The UE is configured to establish an ENDC connection with an enB and one or more gNBs. The UE implements intelligent transmission modification and cell measurement adjustments to mitigate overheating and reduce battery drain.

Abstract: Embodiments are presented herein of apparatuses, systems, and methods for a C-V2X capable wireless device configured to operate according to a first sidelink mode where communication resources are allocated by a network and a second sidelink mode where communication resources are autonomously allocated by the wireless device. The wireless device detects a change in a coverage scenario associated with the first sidelink mode; performs resource sensing for the second sidelink mode; and based at least in part on detecting the change in the coverage scenario, transmits first communications using the second sidelink mode, wherein resources for transmitting the first communications are allocated based at least in part on the resource sensing.

Abstract: A relay user equipment (UE) configured to operate as a relay between a remote UE and a network component performs a method. The method includes determining at least one relay capability of the relay UE and performing a relay access control operation that indicates to the remote UE whether the remote UE is permitted to use the relay UE as the relay.
