Abstract: A user equipment (UE) may be barred from accessing one or more network slices. The UE collects information to perform an access barring procedure corresponding to a cell of a network, performs an accessing barring procedure using the information, performs a random access channel (RACH) procedure with the cell and establishes a radio resource control (RRC) connection with the cell.

Abstract: A base station of a network operates as a serving cell for a user equipment (UE) and configures the UE to measure channel state information reference signals (CSI-RS) from the target cell. The base station determines whether a target cell of the network transmits Synchronization Signal Block (SSB) information and transmits, to the UE, a measurement configuration message indicating the UE is to measure channel state information reference signals (CSI-RS) from the target cell, wherein the measurement configuration message does not include SSB information for the target cell but further comprises an indication of whether the target cell transmits SSBs.

Abstract: A user equipment (UE) supports an independent measurement gap configuration. The UE transmits an indication to a currently camped cell indicating that the UE supports an independent measurement gap configuration for new radio in an unlicensed spectrum (NR-U), receives measurement gap configuration information from the currently camped cell, configures a measurement gap pattern based on the measurement gap configuration information and receives a signal from a cell during a measurement gap of the measurement gap pattern.

Abstract: A user equipment (UE) monitors a Physical Downlink Control Channel (PDCCH) in multiple component carriers (CC). The UE determines if the UE is operating in carrier aggregation (CA) mode having a first CC in a first frequency band and a second CC in a second frequency band. When the UE is operating in CA with a first CC in the first frequency band and the second CC in the second frequency band, the UE determines a span pattern for PDCCH symbols being received on the first and second CC and selects a PDCCH monitoring type based on, at least, the span pattern. A UE also determines if a first CC and a second CC of a CA combination are collocated and selects a PDCCH monitoring type based on, at least, the determination of whether the first and second CC are collocated.

Abstract: A user equipment (UE) and a base station exchange communications to enable the UE to switch beams. The UE receives a physical uplink control channel (PUCCH) resource configuration from the base station, wherein the PUCCH resource configuration includes a plurality of PUCCH resources, receives a signal from the base station based on which one of the plurality of PUCCH resources is activated, performs a beam switching operation to change a transmission beam to a beam corresponding to the activated PUCCH resource and transmits periodic uplink (UL) data using the beam corresponding to the activated PUCCH resource.

Abstract: A user equipment (UE) may attempt to access an edge data network. The UE generates a first credential based on a second credential, the second credential generated for a procedure between the UE and a cellular network, generating an identifier corresponding to the first credential, and generates a multi-access edge computing (MEC) authorization parameter. The UE then transmits an application registration request message to a server associated with an edge data network, the application registration request message including an indication of the first credential, the identifier corresponding to the first credential and the first authorization parameter. The UE then receives an authentication accept message or an authentication reject message from the server associated with the edge data network.

Abstract: A base station serving a user equipment (UE) may signal a transmission configuration indicator (TCI) state change for more than one control resource set (CORESET). The base station has one or more processors configured to configure, for the UE, a group of control resource sets (CORESETs), the CORESET group including a plurality of CORESETs, signal, to the UE, the CORESET group including the plurality of CORESETs and indicate, to the UE, a transmission configuration indicator (TCI) state change for one or more of the plurality of CORESETs in the CORESET group via a medium access control (MAC) control element (CE).

Abstract: User equipment (UE) operation in a single frequency network (SFN). The UE may receive one or more transmission configuration indication (TCI) states corresponding to one or more downlink resources, receive a demodulated reference signal (DMRS) wherein the DMRS is quasi co-located (QCLed) with one or more channel state information reference signal (CSI-RS) from multiple cells of a SFN and quasi co-location (QCL) information is included in the one or more TCI and determine a time and frequency offset corresponding to each of the multiple cells based on the CSI-RS.
