Abstract: Systems, methods, and circuitries are provided for performing sidelink communication. In one example, a user equipment (UE), includes a memory and one or more processors configured to, when executing instructions stored in the memory, cause the UE to determine a SCI stage 2 scrambling initialization value (Cinit) based on at least a portion of a physical sidelink control channel (PSCCH) cyclic redundancy check (CRC) code and a resource pool constant NCONST_RP, wherein NCONST_RP is configured for a resource pool allocated for sidelink communication by the UE; generate a scrambling sequence based on the SCI stage 2 Cinit; and transmit a SCI stage 2 to the second UE based on the scrambling sequence.

Abstract: Apparatuses, systems, and methods for user equipment device (UE) uplink antenna panel selection. The UE may determine, based on at least one condition, to perform a beam switch from a current beam being used for communications with a base station. The UE may transmit, to the base station, an indication of an antenna panel status that may include an indication of a latency associated with the beam switch. The UE may receive, from the base station, an indication to switch to a target beam and to perform the switch, based on the indication, to the target beam. The indication of the antenna panel status may include a beam switching latency level for each beam in a beam report, a beam switch request that may indicate the target beam, and/or a beam switch request that may indicate that an antenna panel switch is to be applied by the UE.

Abstract: The present application relates to devices and components including apparatus, systems, and methods to perform cell reselection. In an example, timing requirements for synchronization signal processing are defined based on a beam sweeping capability of the device. Synchronization signals are received and processed according to the timing requirements to complete a cell reselection procedure. In another example, location data of the device is used to look up a database of cell identifiers. A cell identifier is determined based on the look-up and a cell reselection procedure is performed using the cell identifier.

Abstract: A user equipment (UE) in a wireless network including a first next generation NodeB (gNB) and a second gNB for communicating with the UE performs operations. The operations include determining to transmit a first transmission (Tx) stream and a second Tx stream simultaneously to the first gNB and the second gNB for handing over communication with the UE from a first cell to a second cell, wherein the first gNB is a serving gNB in the first cell and the second gNB is a handover target gNB in the second cell and simultaneously transmitting within a same antenna panel of the UE the first transmission stream to the first gNB using a first polarization and the second transmission stream to the second gNB using a second polarization different from the first polarization.

Abstract: Methods and systems to activate beams for beam switching based on measurements of a downlink reference signal that is QCL Type-D with a downlink pathloss reference signal are disclosed. A UE may measure and report to a base station the RSRP of the reference signal that is QCL Type-D with a target downlink pathloss reference signal. Based on the reported RSRP measurements, the base station may activate the target pathloss reference signal to command the UE to update the pathloss measurements of the target pathloss reference signal for uplink power control of a beam corresponding to the target pathloss reference signal. The UE may determine whether the target pathloss reference signal is considered known for uplink power control based on the timing relationship among the reception of the reference signal from the base station, the transmission of the RSRP measurement of the reference signal, and reception of the activation command.

Abstract: Some embodiments include an apparatus, method, and computer program product for enhanced direct secondary cell activation in a 5G wireless communications system. A user equipment (UE) can receive a Radio Resource Control (RRC) command from a 5G Node B (gNB) via a Primary Cell (PCell) or via a Primary Secondary Cell (PSCell) that includes configuration data for a Secondary Cell (SCell), where the SCell operates in Frequency Range 2 (FR2). The RRC command includes a first Transmission Configuration Indicator (TCI) state for the SCell, and the UE can activate the SCell for the UE based at least on the configuration data, concurrently with the first TCI state for receiving the PDCCH transmission. The UE can receive a Physical Downlink Control Channel (PDCCH) transmission via a first antenna beam from the SCell, where the first antenna beam is based on the first TCI state.
