Abstract: Some aspects of this disclosure relate to apparatuses and methods for implementing downlink and uplink scheduling in communication above 52.6 GHz. For example, some aspects of this disclosure relate to a base station. The base station includes a transceiver configured to communicate over a wireless network with a user equipment (UE) and a processor communicatively coupled to the transceiver. The processor determines that the communication between the base station and the UE is in a frequency range above 52.6 GHz. In response to the determination, the processor disables a frequency main resource assignment (FDRA), modifies a Resource Block Group (RBG) size, or modifies a Resource Indication Value (RIV) determination. The processor generates a Downlink Channel Indicator (DCI) based at least on one or more of the disabled FDRA, the modified RBG size, or the modified RIV determination. The processor transmits, using the transceiver, the DCI to the UE.

Abstract: Provided is a method for a user equipment (UE). The UE obtains, from a network device, a first configuration information. The first configuration information indicates a first resource set for an aperiodic Sounding Reference Signal (AP-SRS). The first resource set for the AP-SRS includes a first list of slot offsets. The UE decodes a second configuration information from the network device. The second configuration information indicates a reference slot and a first slot offset of the first list of slot offsets. The UE generates the AP-SRS for transmission to the network device based on the reference slot and the first slot offset.

Abstract: A base station maps physical downlink control channel (PDCCH) candidates and PDCCH transmissions for multi-transmission reception point (TRP) operation. The base station determines that a control resource set (CORESET) is to be shared by at least a first TRP and a second TRP corresponding to a cell of a network, performs resource element group (REG) bundle to virtual REG bundle mapping on a per TRP basis, wherein multiple REG bundles are indexed on the per TRP basis, performs virtual REG bundle interleaving across the first TRP and the second TRP, performs control channel element (CCE) to interleaved REG bundle mapping and transmits downlink control information (DCI) using the CORESET, wherein the CORESET is configured based on, at least, the CCE to interleaved REG bundle mapping.

Abstract: Apparatuses, systems, and methods for beam indication latency reduction via a symbol level beam sweeping configuration. A base station may receive, from a user equipment device (UE), a report associated with symbol level beam sweeping. The base station may determine a symbol level beam sweeping configuration. The symbol level beam sweeping configuration may be based, at least in part, on the report. The base station may transmit, to the UE, the symbol level beam sweeping configuration.

Abstract: A cell performs beam management operations for a user equipment (UE). The cell transmits a first group of multiple reference signals via a first transmission reception point (TRP) to a user equipment (UE), transmits a second group of multiple reference signals via a second different TRP to the UE, receives an indication that the UE has selected a first beam associated with one of the multiple reference signals of the first group and a second beam associated with one of the multiple reference signals of the second group and transmits downlink data to the UE using the first beam and the second beam.

Abstract: The disclosure describes frame structure with downlink/uplink subframe configuration and channel hopping scheme for unlicensed narrowband Internet-of-Things (IoT) systems. An apparatus operable for unlicensed narrowband transmission to support IoT service is disclosed. The apparatus includes baseband circuitry to select a transmission channel within an unlicensed narrow band for downlink transmission of a discovery reference signal (DRS), and for channel hopping, to select, according to the DRS, a communication channel within the unlicensed narrow band for downlink data and uplink data. The DRS includes a primary synchronization signal (PSS), a secondary synchronization signal (SSS) and physical broadcast channel (PBCH) content. The baseband circuitry is further to demodulate a received signal received via radio frequency (RF) circuitry through the communication channel over an uplink frame, and to modulate a transmitting signal to be transmitted via the RF circuitry through the communication channel over a downlink frame.
