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: A user equipment (UE) is configured to utilize wake up signaling during paging operations. The operates in a paging discontinuous reception (DRX) cycle, wherein the paging DRX cycle includes a paging occasion (PO). The UE receives a wake-up signal (WUS) during a WUS occasion that is associated with the PO and selects a mode of operation to utilize during the PO based on the WUS.

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: A computer readable storage medium, a user equipment, a method and an integrated circuit that are used to perform operations. Operations include receiving, from a network, a plurality of Physical Downlink Shared Channel (PDSCH) transmissions in slots of a hybrid automatic repeating request acknowledgement (HARQ-ACK) window, decoding each of the PDSCH transmissions in the slots of the HARQ window, determining a HARQ-ACK feedback for each PDSCH transmission in the HARQ-ACK window, bundling the HARQ-ACK feedback for at least two of the PDSCH transmissions and reporting the bundled HARQ-ACK feedback for the HARQ window to the network.

Abstract: One embodiment described herein takes the form of a user equipment (UE), such as a phone. The UE includes a transceiver and a processor. The processor is configured to establish a first radio resource control (RRC) connection with a base station via the transceiver. The processor is configured to associate with a secondary UE for collaboration of transmission of a data payload of one of the UE or the secondary UE to the base station, and transmit a first portion of the data payload to the base station via the transceiver.

Abstract: A user equipment (UE) may operate on a dormant bandwidth part (BWP) and a non-dormant BWP of a carrier. The UE identifies a dormant bandwidth part (BWP) and a non-dormant BWP of a carrier corresponding to a primary secondary cell (PSCell) of a secondary cell group (SCG) for dual connectivity (DC), determines that the dormant BWP is configured in an active state and performing one or more actions corresponding to the dormant BWP.
