Abstract: A network may authenticate a user equipment (UE) to access an edge data network. The network generates a first credential based on a second credential, the second credential generated for a procedure between the UE and a cellular network corresponding to the network component, receives an identifier associated with the first credential from a further network component in response to the UE transmitting an application registration request to a server associated with an edge data network and retrieves the first credential based on the identifier. The network also receives a multi-access edge computing (MEC) authorization parameter, verifies the MEC authorization parameter and transmits an authentication verification response to a second network component.

Abstract: To extend a physical broadcast channel (PBCH) in wireless communications, an extended physical broadcast channel (EPBCH) transmission is generated with one or more legacy PBCH blocks and one or more EPBCH blocks within an extension window. A size of the extension window is determined based at least in part on a PBCH repetition number and a number of the legacy PBCH blocks relative to a number of the EPBCH blocks. The EPBCH transmission is transmitted by a base station (BS) to one or more user equipment (UE).

Abstract: Systems and methods for using integrated access and backhaul (IAB) nodes configured to provide multi-access edge computing (MEC) functionality are disclosed herein. An TAB node includes a distributed unit (DU) having a local application instance of a MEC-enabled application. The local application instance is configured for communication with a first user equipment (UE) connected to the TAB node. A mobile termination functionality (MT) of the TAB node uses a packet data convergence protocol (PDCP) layer to transport data of the local application instance between the MT and an IAB donor. Further, data of the local application instance is transported between the UE and the TAB node via one of a variety of methods, including the use of a second PDCP layer at the DU (and optionally the use of service data adaptation protocol (SDAP) layers at each of the DU and the MT), and/or via sidelink.

Abstract: Systems, methods, and circuitries are provided for supporting aggregated retransmissions. In one example, a method includes receiving control information that indicates resources including one or more slots for communication of a physical downlink shared channel (PDSCH) or a physical uplink shared channel (PUSCH) transmission that includes at least one PDSCH/PUSCH retransmission A slot group to which a selected one of the one or more slots belongs is identified. The method includes configuring operation to receive the PDSCH transmission or to transmit the PUSCH transmission based on the resources. In response to determining that a PDSCH/PUSCH retransmission of the PDSCH/PUSCH transmission is scheduled for a slot outside the identified slot group, operation is configured to provide hybrid automatic repetition request (HARQ) feedback based on PDSCH/PUSCH retransmissions scheduled for slots within the identified slot group, wherein the HARQ feedback is not based on PDSCH/PUSCH scheduled for slots outside the identified slot group.

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: This disclosure relates to using a wake up signal in conjunction with cellular communication in unlicensed spectrum. A cellular base station may provide a wake up signal on an unlicensed frequency channel after successful completion of a listen-before-talk procedure. The wake up signal may include a preamble configured for coherent detection, and information indicating channel occupancy time for a cellular communication by the cellular base station and a cell identifier for the cellular base station. A wireless device may monitor the unlicensed frequency channel for a wake up signal, and may determine whether to monitor the unlicensed frequency channel for control channel signaling based on whether a wake up signal is received, and potentially also based on the contents of the wake up signal if a wake up signal is received.

Abstract: Techniques for identity-based message integrity protection and verification between a user equipment (UE) and a wireless network entity, include use of signatures derived from identity-based keys. To protect against attacks from rogue network entities before activation of a security context with a network entity, the UE verifies integrity of messages by checking a signature using an identity-based public key PKID derived by the UE based on (i) an identity value (ID) of the network entity and (ii) a separate public key PKPKG of a private key generator (PKG) server. The network entity generates signatures for messages using an identity-based private key SKID obtained from the PKG server, which generates the identity-based private key SKID using (i) the ID value of the network entity and (ii) a private key SKPKG that is known only by the PKG server and corresponds to the public key PKPKG.
