Abstract: A device, system and method for a user equipment (UE) to opportunistically utilize the wireless capabilities of a paired device. The UE is configured to establish a first cellular network connection based on a first subscription, a second cellular network connection based on a second subscription and a connection to a further UE based on a short-range communication protocol. The UE identifies a predetermined condition and transmits an indication to the further UE based on the predetermined condition. The further UE establishes a further cellular network connection in response to the indication and the further cellular network connection is based on one of the first subscription or the second subscription. The UE then declares no service for one of the first cellular network connection or the second cellular network connection based on the further cellular network connection.

Abstract: The present disclosure relates to opportunistically selecting an antenna in an electronic device having multiple antennas. A baseband processor of the electronic device may connect to a first cellular tower providing cellular service at a first frequency using a first antenna of the electronic device. The baseband processor may then receive an indication of a handover event to a second cellular tower operating at a second frequency. The baseband processor may determine signal measurements of the second cellular tower for each antenna of the electronic device that is capable of operating at the second frequency. The baseband processor may execute a handover to the second cellular tower using the antenna associated with the best performing signal measurements. In this manner, an antenna may be opportunistically selected based on performance of the antenna, improving operation of the electronic device and quality of cellular service.

Abstract: This application describes methods and apparatus to manage data transport across multiple radio links for 5G-capable wireless devices. Under certain criteria, including performance of at least one radio link, a mobility state of a 5G-capable wireless device, and data transport requirements for a latency sensitive application session, the 5G-capable wireless device sends buffer status report (BSR) requests for one or more both of the radio links to prioritize and transition uplink (UL) data between radio links before a measurement reporting threshold is met. In some embodiments, the 5G-capable wireless device proactively sends BSR requests for radio resources before the UL data is generated by the latency sensitive application session. In some embodiments, the 5G-capable wireless device duplicates UL data for the latency sensitive application session across multiple radio links.

Abstract: Techniques, described herein, may enable a vehicle to engage in vehicle-to-everything (V2X) communications via PC5 sidelink (SL), even when the vehicle does not have a global positioning system (GPS) or other type of satellite signal. While receiving a satellite signal, the vehicle may pre-store future geographic locations based on a travel route and upon detecting a loss of the satellite signal, the vehicle may estimate a geographic location of the UE based on one or more types of information, such as mapping or navigation capabilities of the UE, a travel time since the signal failure or last estimated geographic location, a travel velocity since the since the signal failure or last estimated geographic location, etc. The vehicle may determine, based on an estimated geographic location, that physical resources are appropriate for SL communications and begin using the physical resources accordingly.

Abstract: A wireless device may comprise antennas and a processor configured to cause the wireless device to determine preferred antenna ports for at least one primary component carriers (PCCs) and at least one secondary component carriers (SCCs) based on performed downlink measurements of antenna ports. The wireless device may further determine support capabilities of the wireless device and perform computations using additional measurements of the antenna ports. Based on the computations, the wireless device may assign the preferred antenna ports to the PCCs and SCCs and perform uplink transmission using the assigned antenna ports.

Abstract: Multi-radio wireless network devices are capable of transmitting and/or receiving data from multiple radiofrequency (RF) networks at different bands. Total transmission power limitations may be in place due to, for example, safety reasons. As a result, active management of transmission power may be performed during simultaneous transmission in different bands and/or networks. In some embodiments, the management may take place on group-by-group basis and a network-by-network basis. Antennas may be grouped based on their relative positions and impact on radiation emitted by the devices.

Abstract: The present application relates to improving a roaming service. In an example, user equipment (UE) initiates a cell selection process to choose between a first cell and a second cell. The UE evaluates a first uplink (UL) channel condition of the first cell and a second UL channel condition of the second cell based on the initiation. The UE selects the first cell or the second cell based on the evaluated first UL channel condition and second UL channel condition. The UE initiates a random access channel (RACH) procedure based on the selected first cell or second cell.

Abstract: Systems and methods for extending connectivity with a cellular network are disclosed herein. A UE may monitor a serving cell of the UE and a neighbor cell of the UE to determine whether there is a network condition wherein the UE is to transition to an out-of-service (OOS) state if it were to fall to an Radio Resource Control (RRC) Idle state. The UE may react by, before expiration of an inactivity period corresponding to a transition to an RRC Idle mode, initiating signaling activity with a radio access network (RAN) node of the serving cell. In other embodiments, the UE may determine, based on a number of secondary devices connected to the UE, to initiate signaling with the RAN node of the serving cell before expiration of an inactivity period and according to whether a maximum number of extensions of an extension activity period has been reached.
