Abstract: Apparatuses, systems, and methods for beam indication latency reduction via a symbol level beam sweeping configuration. A base station may receive, from a user equipment device (UE), a report associated with symbol level beam sweeping. The base station may determine a symbol level beam sweeping configuration. The symbol level beam sweeping configuration may be based, at least in part, on the report. The base station may transmit, to the UE, the symbol level beam sweeping configuration.

Abstract: MBS key distribution includes processing group information associated with an MB session context received from an AF. At least a portion of the group information comprises a TMGI. A plurality of session join requests received from a plurality of UEs are processed. Each of the plurality of session join requests include the TMGE and are associated with the MB session context. A request associated with the MB session context for transmission to an MB-SMF is encoded. A response associated with the MB session context received from the MB-SMF is processed. The response includes a key derived for each of a portion of the plurality of UEs using a UE ID and the TMGI. A DL NAS message and an N2 message are encoded for the plurality of UEs and a base station, respectively. The DL NAS message and the N2 message include the derived key.

Abstract: Embodiments are presented herein of apparatuses, systems, and methods for a user equipment device (UE) and a network to perform flexible acknowledgement. A UE may determine whether or not to solicit feedback (e.g., HARQ ACK/NACK) for one or more groupcast transmissions. The determination may be based on factors such as a remaining time to perform the transmission and the amount of time needed to perform the transmission with and without allowing time to receive and process feedback.

Abstract: Various embodiments are described for apparatuses, systems, and methods for pre-forwarding data packets for conditional handover. A UE may connect to a serving base station and perform measurement(s) of one or more neighboring base stations. The UE may provide measurement report(s) corresponding to the measurement(s) to the serving base station. The UE may receive handover assistance information from the serving base station. The handover assistance information may identify at least one neighboring base station that receives downlink packet forwarding of downlink packets intended for the UE prior to handover. The UE may evaluate handover conditions of the neighboring base stations, including the at least one neighboring base station. The UE may perform handover to a first neighboring base station of the at least one neighboring base station based on the at least one neighboring base station receiving downlink packet forwarding of downlink packets intended for the UE prior to handover.

Abstract: Apparatuses, systems, and methods for application function (AF) key generation and AF key renewal. A user equipment device (UE) may communicate with an application function (AF) via a radio access network (RAN) using a first AF key and determine that the first AF key has expired. The UE may derive a second AF key based on at least an Architecture for Authentication and Key Management for Applications (AKMA) anchor key (KAKMA) and a counter parameter and communicate with the AF via the RAN using the second AF key. At least one of the UE, the AF, and/or an AKMA Anchor Function (AAnF) may be configured to monitor expiration of the first AF key based on an associated lifetime of the first AF key. The first and second AF keys may be derived using a key derivation function that includes at least one variable parameter.

Abstract: A user equipment (UE) includes first and second subscriber identity modules (SIMs), possibly subscribed to different carriers. When the first SIM is in a connected state and the second SIM is in an idle state, the UE may need to periodically tune away a radio from a first frequency used for communication under the first SIM to a second frequency used for idle mode activity under the second SIM. The UE may provide to the network of the first SIM the second SIMs traffic activity pattern and/or serving frequency so that the network may provide coordinated configuration and/or scheduling for the UE device, e.g., in order to make the action of tuning away (and tuning back) the radio more efficient and/or to decrease the network impact of such radio tune aways (e.g., to decrease wasted uplink scheduling and wasted downlink transmissions for the first SIM).

Abstract: Apparatuses, systems, and methods for a wireless device to perform methods to communicate an RRC message (such as an RRC configuration message) having a size that exceeds PDCP SDU size constraints. According to some embodiments, a base station may generate a large RRC message, e.g., by encoding an RRC configuration as a single large RRC message. The base station may then segment the RRC message, e.g., at the RRC layer or the PDCP layer, into a series of PDUs that comply with the size constraints. According to some embodiments, the base station may encode an RRC configuration as a series of RRC messages, each complying with the size constraints. The base station may further provide an indication of when a receiving user equipment should apply the RRC configuration.

Abstract: Apparatuses, systems, and methods for a wireless device avoiding reselection or handover to cells of different operators. The wireless device may attach to a first base station of a first network operator. The wireless device may determine that a neighboring base station is associated with a second network operator. Based on determining the neighboring base station is associated with the second network operator, the wireless device may exclude the third base station from handover or reselection.
