Abstract: Systems, methods and devices can are provided, which can include configuring one or more bandwidth parts for a secondary cell (SCell) that is in communication with a user equipment (UE). A base station transmits to a UE a first radio resource control (RRC) message including one or more configuration parameters for a first bandwidth part (BWP) associated with a secondary cell (SCell). The UE communicates a first message with the SCell via the first SCell BWP. The UE receives a second RRC message indicating a change from the first SCell BWP to a second SCell BWP to be used for SCell communications. The UE communicates a second message with the SCell via the second SCell BWP.

Abstract: A UE may perform a location-based conditional handover (CHO) based on a region information and size parameter associated with a serving cell of a non-terrestrial network (NTN). In time-based CHO, the UE may perform CHO in response to expiration of a network-configured wait time. Alternatively, the UE may perform CHO by randomly selecting a wait time from a network configured time range. The selection may be randomized using a network provided seed or using a cell Radio Network Temporary Identifier (RNTI) value. In elevation-based CHO, the UE may perform CHO in response to the elevation angle of a satellite being less than a network configured threshold. When the UE is configured with multiple cells of the NTN, and the CHO criteria for two or more of the cells are satisfied, the UE may select a target cell for CHO based on network indicated prioritization of the cells.

Abstract: Methods and apparatuses are disclosed for configuring full power transmission modes in a UE. The disclosed full power transmission modes include a Mode 0 and a Mode 3, which are enhancements over previous modes disclosed in the 3GPP specification. The UE gathers supported modes and configuration capabilities, such as number of ports and supported coherency schemes, and forwards the configuration capabilities to the network. The network analyzes the received information and selects a supported full power transmission mode based on the UE capabilities. The selection is then transmitted to the UE in a PUSCH-Config message. The UE extracts the selection from the PUSCH-Config message, and configures its radio accordingly.

Abstract: A network mitigates paging false alarms. A network component of the network determines a paging area for a user equipment (UE), wherein the paging area comprises a plurality of cells of the network, determines one of a most recent one of the cells of the paging area with which the UE was in a radio resource control (RRC) connected state or a coverage area of one of the cells in which the UE is currently located and configures a page to be transmitted to the UE from a subset of the plurality of cells of the paging area, wherein the subset is based on at least the determination of the most recent one of the cells with which the UE was in a radio resource control (RRC) connected state or the one of the cells in which the UE is currently located.

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: A user equipment (UE) is configured to receive cell information including related frequency and network slice information. The UE receives network slice based dedicated priority information for the UE from a currently camped cell, selects a frequency band for camping based on a configured network slice and the network slice based dedicated priority information and establishes a protocol data unit (PDU) session with the configured network slice when camped on the frequency band.

Abstract: Systems and methods for using a relay user equipment (UE) to transport data of interest received from a first remote UE to a second remote UE on a UE to UE relay within a wireless communication system are discussed herein. These methods may be performed at Layer 2 of a protocol stack of the wireless communication system. Data packets sent on the UE to UE relay may include an adaptation header including routing information (e.g., Layer 2 addresses, a bearer-specific index, etc.) for the UE to UE relay. An adaptation layer may accordingly be provided within Layer 2 to decode these adaptation headers. In some cases, a per-bearer approach may be used to map between individual direct bearers of a hop by hop path configuration of the UE to UE relay. Embodiments eschewing the adaptation header and instead using logical channel identifiers (LCIDs) to make routing indications are also described.

Abstract: A user equipment (UE) may be configured with information to perform conditional handovers or addition/change of a primary secondary cell (PSCell). The UE receives a first radio resource control (RRC) configuration message from the source cell for conditional handover to the at least one target cell, the first RRC configuration message including conditional handover execution conditions, an RRC configuration and a target cell ID for each one of a list of target cells, performs measurements on the target cells to determine whether any one of the target cells fulfills its corresponding conditional handover execution conditions and, when a first target cell from the list of target cells fulfills its corresponding conditional handover execution conditions, initiates a handover to the first target cell.
