Abstract: Methods, systems and apparatus for a user equipment to mitigate interference in a wireless charging state. The user equipment may determine when the user equipment enters a wireless charging state and, when the user equipment enters the wireless charging state, activate an interference mitigation. The user equipment may further determine when the UE exits the wireless charging state and, when the user equipment exits the wireless charging state, deactivate the interference mitigation.

Abstract: This disclosure relates to techniques for avoiding denial of service in a wireless communication system. A wireless device may unsuccessfully attempt to obtain cellular service. Based at least in part on cause information for the unsuccessful attempt to obtain cellular service, and potentially also based at least in part on cause information for one or more previous unsuccessful attempts to obtain cellular service, the wireless device may selectively determine to disable one or more features at the wireless device, bar a cell on which the unsuccessful attempt to obtain cellular service is made, bar a public land mobile network on which the unsuccessful attempt to obtain cellular service is made, and/or bar a radio access technology according to which the unsuccessful attempt to obtain cellular service is made and perform a subsequent attempt to obtain cellular service.

Abstract: This disclosure relates to techniques for supporting cell set based mobility. A network may provide configuration information to a wireless device, relating to a current cell and possibly to one or more other cells in one or more cell sets. The wireless device and network may take various measurements. In response to the measurements and the configuration information, the wireless device may perform a cell change to one of the other cells.

Abstract: Apparatuses, systems, and methods for enhancement of MBMS transmission reliability. A UE may receive PDCP PDUs via a PTM link from a network. The UE may determine to provide feedback regarding receipt of the PDCP PDUs, e.g., based, at least in part, on an occurrence of a triggering event. The triggering event may be configured by the network and may include the UE receiving a request for feedback from the network, the UE determining that at least one PDCP PDU is missing, the UE determining that a number of missing PDCP PDUs exceeds a threshold, and/or the UE determining that a PDCP reordering window is changing based on expiration of a PDCP reordering timer. The UE may transmit feedback associated with receipt of the PDCP PDUs. The feedback may include an indication of missing PDCP PDUs, e.g., such as an indication of a sequence number associated with missing PDCP PDUs.

Abstract: A communications system may include a data collection server (DCS) that receives contextual information from a set of UE devices. The DCS may aggregate the contextual information into a database. A given UE may proactively identify an optimal network configuration to use in communicating with a cellular network. The UE may generate local contextual information. The UE may request a set of entries from the database corresponding to a set of geographic tiles overlapping or neighboring its location. The UE may select the optimal network configuration based on its local contextual information and the requested entries. The UE may transmit a request to a base station to perform communications under the optimal network configuration using user equipment assistance information (UAI) of a radio resource control (RRC) signal. Proactive selection of the network configuration may optimize performance given the current UE operating context without requiring reactive network configuration adjustments.

Abstract: This disclosure relates to a relay user equipment device (UE) assisting one or more remote UEs in performing a radio access network notification area (RNA) update procedure in a cellular communication system. The relay UE establishes a first relay connection with a first remote device. The first relay connection relays communications between the first remote device and a network. The relay UE transmits a first message to the network to initiate the RNA update procedure for the first remote device, receives an acknowledgment message from the network including updated connection information for the first remote device, and transmits the updated connection information to the first remote device.
