    Abstract: Apparatuses, systems, and methods for enhancement in NTN mobility. A cellular base station may serve as a source base station of a handover procedure from the source base station to a target non-terrestrial network (NTN) base station. The cellular base station may configure a parameter associated with the target NTN base station in a handover command, the parameter being related to NTN mobility, and send the handover command to a wireless device for use by the wireless device during the handover procedure. The wireless device may receive the handover command from the cellular base station, and perform the handover procedure using the parameter associated with the target NTN base station.

    Abstract: Disclosed herein are system, method, and computer program product embodiments for implementing multiple receive (multi-Rx) chain downlink (DL) reception when the receive timing difference (RTD) at a user equipment (UE) from multiple transmission and reception points (TRPs) is greater than the cyclic prefix (CP). An embodiment operates by configuring a first base station (BS) to transmit a first data and a second BS to transmit a second data simultaneously to a user equipment (UE) during a first symbol period, where the first data from the first BS is received by the UE using a first receive beam and the second data from the second BS is received by the UE using a second receive beam. The embodiment also configures the first BS to transmit a reference signal (RS) to the UE during a second symbol period that is subsequent to the first symbol period. The embodiment then determines a scheduling restriction applied to the second BS during a plurality of symbol periods, wherein the plurality of symbol periods include the second symbol period. Finally, the embodiment provides the scheduling restriction the second BS.

    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.

    Abstract: Systems and methods for determining a timing of a random access channel (RACH) occasion (RO) used to transmit a contention free random access (CFRA) preamble triggered by the receipt of an physical downlink control channel (PDCCH) order in a PDCCH are disclosed herein. A user equipment (UE) receives the PDCCH order and determines a timing offset value between the RO and a signal (e.g., a synchronization signal block (SSB), the PDCCH, a reference signal, etc.) to be used as a timing source. The UE also determines the arrival time of the signal to be used at the timing source. The UE then determines a time of the RO (during which the CFRA preamble will be transmitted) according to the arrival time and the timing offset value. Timing advance (TA) value(s) may also be accounted for as part of such a determination.

    Abstract: Some aspects include an apparatus, method, and computer program product for radio resource management measurement prioritization for reduced capacity (RedCap) user equipment (UE). A RedCap UE may be use Half-Duplex Frequency Division Duplex (HD-FDD) for wireless communications. When performing communications with a network, the RedCap UE may make several measurements, including Reference Signal Received Power (RSRP), Signal to Interference and Noise Ratio (SINR), and Reference Signal Received Quality (RSRQ) measurements. To obtain these measurements, the RedCap UE may measure Synchronization Signal Block (SSB), Received Signal Strength Indicator (RSSI), and/or Channel State Information Reference Signal (CSI-RS) symbols. Difficulties may arise when a RedCap UE's serving cell signal timing is not synchronized with a neighboring cell. The RedCap UE may be configured to prioritize measurements over uplink transmissions. This prioritization may also include symbol buffers so that an overlap in uplink transmissions does not occur during a measurement.
