    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: Some embodiments include an apparatus, method, and computer program product for using low layer protocols for inter-cell mobility management in a 5G wireless communications system. A serving 5G node B (gNB) can configure reports that a user equipment (UE) transmits to the serving gNB to make handover decisions. The serving gNB can configure a group of Transmission Configuration Indication (TCI) states (e.g., a group of beams) that correspond a physical cell, and the report includes layer 3 measurements corresponding to a neighboring or serving cell's TCI state. The report can be conveyed using lower layer protocols. The report can include layer 1 measurements conveyed using a layer 1 protocol and the serving gNB can perform filtering to generate corresponding layer 3 measurement results. Based on the reports, the serving gNB can perform a handover and synchronization using lower layer protocols, from one TCI state to another.

    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.

    Abstract: An apparatus of a next generation Node B (gNB) comprises one or more baseband processors to generate an indication for a user equipment (UE) to indicate which synchronization signal block (SSB) based measurement timing configuration (SMTC) occasion can be used by the UE for one or more measurements, and to send the indication to the UE. The apparatus can include a memory to store the indication.

    Abstract: Embodiments of the present disclosure relate to methods, a terminal device, a network device, and computer program products for SCell management in wireless communication. A terminal device receives from a network device configuration information for configuring a triggering mode. The triggering mode is for triggering activation of a secondary cell of the terminal device and a transmission of a temporary reference signal in the secondary cell. Based on the configured triggering mode, the terminal device receives first triggering information on the activation of the secondary cell and second triggering information on the transmission of the temporary reference signal for performing the activation of the secondary cell. In this way, it is possible to reduce the latency of activation/de-activation procedure for SCG and secondary cells.
