Abstract: A network configures and transmits paging information. The network transmits configuration information to a user equipment (UE) operating in the network, wherein the configuration information comprises a value N based on a minimum gap between reception of a paging downlink control information (DCI) by the UE and fully processing the paging DCI by the UE, configures a paging DCI to be transmitted to the UE on a Physical Downlink Control Channel (PDCCH), wherein the paging DCI includes scheduling information for a Physical Downlink Shared Channel (PDSCH) and transmits the paging DCI to the UE on the PDCCH.

Abstract: A user equipment (UE) configured to monitor paging occasions of a network. The UE operates in a paging discontinuous reception (DRX) cycle, wherein the DRX cycle includes a paging occasion (PO). The UE determines a location in time for a wake-up signal (WUS) occasion associated with the PO and determines whether to utilize an active mode or a sleep mode during the PO based on an indication included in a WUS received during the WUS occasion.

Abstract: Performing a UE-triggered lower layer-based handover may include performing measurements of source gNB CSI-RS samples associated with a source gNB. Measurements of target gNB CSI-RS samples associated with a target gNB may be performed, wherein the CSI-RS samples associated with the source gNB and the CSI-RS samples associated with the target gNB are transmitted in a burst structure. A subset of the source gNB CSI-RS samples and the target gNB CSI-RS samples may be filtered using a layer 1 or a layer 2 filter. A filtered result for each of the subset of source gNB CSI-RS samples and the subset of target gNB CSI-RS samples may be generated. Based on the generated filtered result for each of the subset of source gNB CSI-RS samples and the subset of target gNB CSI-RS samples, determining whether a handover from the source gNB to the target gNB is to occur.

Abstract: Apparatuses, systems, and methods for a wireless device to perform negotiation of bearer type configuration and/or related parameters. A user equipment device (UE) and/or network may determine a bearer configuration and/or other parameters based on information or measurements of the UE. The UE and the BS may exchange data using a negotiated configuration.

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: 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.

Abstract: Some aspects include an apparatus, method, and computer program product for facilitating control messaging for multi-beam communications in 5G wireless communication systems. Nodes of a 5G network may be generate Medium Access Control Control Elements (MAC CEs) to update User Equipment (UE) with different Component Carrier (CC) settings. The MAC CEs may update a list of CCs to reduce messaging overhead and latency. For example, a MAC CE may indicate an update for a Transmission Configuration Indication (TCI) state for a list of CCs. Similarly, a MAC CE may be used to update a spatial relation for a Sounding Reference Signal (SRS) resource set and/or a SRS resource corresponding to a list of CCs. A MAC CE may also be used to update multiple TCI codepoints having one or two TCI states in a multi-Transmission Reception Point (multi-TRP) scenario.

Abstract: A user equipment (UE) monitoring for a page in a 5G network. The UE monitoring a paging occasion corresponding to the UE in a Physical Downlink Control Channel (PDCCH) to determine whether the paging occasion includes paging downlink control information (DCI), when the PDCCH includes the paging DCI, decoding the paging DCI to determine whether the paging DCI includes scheduling information for a Physical Downlink Shared Channel (PDSCH), determining, based on at least the scheduling information, whether to receive the PDSCH in a scheduled slot that is offset N slots from a scheduled slot in which the paging DCI is received and when it is determined to receive the PDSCH, decoding the PDSCH.
