Abstract: A user equipment (UE) in a multiple transmission and reception point (multi-TRP) configuration having simultaneous connections with a first next generation node B (gNB) and at least one second gNB over a same carrier. The UE divides uplink (UL) resources into a plurality of groups, determines a spatial relation and a pathloss reference signal (RS) for each one of the plurality of groups based on a transmission configuration indication (TCI) indicating a quasi-co-location (QCL) source RS for a downlink channel and transmits UL data on the UL resources corresponding to each one of the plurality of groups to a respective one of the first gNB or the at least one second gNB.

Abstract: A user equipment (UE) reports beam management information to a network. The UE receives a first group of multiple reference signals from a first transmission reception point (TRP) of a network, receives a second group of multiple reference signals from a second different TRP of the network, selects a first beam associated with one of the multiple reference signals of the first group, selects a second beam associated with one of the multiple reference signals of the second group and transmits a message to the network, the message including an indication of the selected first beam and second beam.

Abstract: A method and apparatus of a device that acquires transmission configuration indicator (TCI) information for secondary cell (SCell) activation. In some embodiments, the TCI information is acquired for SCell activation by determining, during secondary cell (SCell) activation, that beam information to enable a user equipment (UE) to make a reliable layer 1 (L1)-Reference Signal Received Power (RSRP) measurement report is unavailable, perform the L1-RSRP measurement using information of one or more Synchronization Signal Blocks (SSBs) during the SCell activation, wherein the one or more processors perform the L1-RSRP measurement using information of one or more SSBs during the SCell activation by identifying, by the UE, one or more detectable SSBs during the SCell activation and using information of the one or more detectable SSBs for the L1-RSRP measurement

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: An evolved Node B (eNB) serves as a primary serving cell (PCell) providing a primary component carrier (PCC) in a licensed spectrum to a user equipment (UE) in a carrier aggregation (CA) scheme. A secondary component carrier (SCC) is provided in an unlicensed spectrum. The eNB monitors parameters of bandwidths in the unlicensed spectrum, when at least one of the parameters indicates a change in availability of a select one of the bandwidths, the eNB generates a control indicator defining the change in availability of the bandwidth and broadcasts the control indicator to the UE, wherein the control indicator affects a modification in a transceiver of the UE associated with the bandwidth.
