Abstract: Techniques to protect a subscriber identity, by encrypting a subscription permanent identifier (SUPI) to form one-time use subscription concealed identifiers (SUCIs) using a set of one-time ephemeral asymmetric keys, generated by a user equipment (UE), and network provided keys are disclosed. Encryption of the SUPI to form the SUCIs can mitigate snooping by rogue network entities, such as fake base stations. The UE is restricted from providing the unencrypted SUPI over an unauthenticated connection to a network entity. In some instances, the UE uses a trusted symmetric fallback encryption key KFB or trusted asymmetric fallback public key PKFB to verify messages from an unauthenticated network entity and/or to encrypt the SUPI to form a fallback SUCIFB for communication of messages with the unauthenticated network entity.

Abstract: Systems and methods for control signaling for beam searching latency reduction are disclosed herein. A g Node B (gNB) may determine that a first Synchronization Signal Block (SSB) and a second SSB are to be spatially correlated and may select a first transmit (Tx) beam to transmit the first SSB and a second Tx beam to transmit the second SSB accordingly. The gNB may also transmit a correlation message including spatial correlation information to help a UE determine the spatial correlation. The UE may measure the first SSB on a first subset of a plurality of receive (Rx) beams and measure the second SSB on a second subset of the plurality of Rx beams, and select an Rx beam for one or both. In some embodiments, channel state information reference signals (CSI-RS) that are quasi co-located (QCLed) with a given SSB may be measured in place of the SSB.

Abstract: Apparatuses, systems, and methods for a user equipment device (UE) to determine a default beam for a dedicated PUCCH/SRS in a CC. The UE may determine a pathloss RS has been configured in the CC, e.g., responsive to the UE determining that spatial relationship information for a default transmission beam has not been configured and determine the default beam for transmissions based, at least in part, on the (configured) pathloss RS. Additionally, responsive to determining that the pathloss RS has not been configured in the CC, the UE may determine that no CORESETs/TCI states for a PDSCH in the CC have been configured and determine the default beam for transmissions based, at least in part, on a default transmission beam in another CC, a CC index, a PRACH procedure; a PUSCH transmission; an SRS transmission, and/or a PUCCH transmission.

Abstract: A user equipment (UE) may establish a connection with a network for transmission of a plurality of data bursts further comprising a plurality of data segments. The UE may transmit, to the network, a first data segment corresponding to a first quality of service flow identifier (QFI) associated with a first quality of service (QoS) flow and a second data segment corresponding to a second QFI associated with a second QoS flow. The UE may be configured to map one or more data segments to one or more QFIs based on at least one of a slice type, a frame type, a modulo operation, and a sequence number. The plurality of data bursts may be transmitted according to at least one of one or more configured grants (CGs), one or more dynamic grants (DGs), and one or more instances of the one or more CGs or one or more DGs.

Abstract: The present application relates to improving coverage and reliability of cellular emergency service. In an example, a relay UE is authorized by a core network to provide a U2N relay for emergency services, where this authorization is based on UE capability information sent to the core network indicating the support of U2N relay emergency functionalities. During a U2N relay discovery, the relay UE indicates, to a remote UE, that this capability can be provided. Accordingly, the remote UE selects the relay UE from a candidate set of relay UEs and a relay communication is established.
