Abstract: Techniques for physical downlink shared channel (PDSCH) and physical uplink shared channel (PUSCH) processing for multiple transmission and reception point (multi-TRP) are disclosed. In some embodiments, determining PDSCH hybrid automatic repeat request-acknowledgement (HARQ-ACK) processing timing may include determining that a user equipment (UE) is configured for single downlink control information (single-DCI) multi-TRP PDSCH operation, determining a first PDSCH and a second PDSCH within a slot, wherein the first PDSCH and the second PDSCH are used in the single-DCI multi-TRP PDSCH operation, and determining a minimum HARQ-ACK processing timing for the first PDSCH and the second PDSCH using one or more symbols of the first PDSCH or one or more symbols of both the first PDSCH and the second PDSCH.

Abstract: Disclosed are techniques for differentiating between licensed and unlicensed bands in a common portion of frequency spectrum to facilitate initial access in a fifth generation (5G) new radio (NR) wireless communication system having an NR node. The techniques include an NR generating and UE processing frequency configuration information indicating whether the common portion of frequency spectrum is allocated as a licensed band or an unlicensed band to enable a determination that the frequency spectrum is configured as the licensed band or unlicensed band and thereby facilitate initial access.

Abstract: Systems and methods disclosed herein describe the use of synchronization signal/physical broadcast channel block measurement time configuration (SMTC) 2 low power (SMTC2-LP) configuration(s). For cell measurements, a UE may determine that an SMTC2-LP configuration for one or more carriers of one or more target cells is known, determine a periodicity of SMTC occasions of the carrier(s) based on data found in the SMTC2-LP configuration(s), and cancel a cell measurement of an inter-frequency cell based at least in part on the periodicity of the SMTC occasion(s). For cell re-selection, a UE may determine that an SMTC2-LP configuration for a carrier being used at a target cell is known and that a physical cell identity (PCI) of the target cell is found in data of the SMTC2-LP configuration, determine a maximum paging interruption time using this periodicity, and perform a cell reselection to the target cell within this time.

Abstract: Techniques for channel state information reference signal (CSI-RS) configuration in wireless communications are disclosed. A user equipment (UE) may decode a message including a CSI-RS configuration that indicates a CSI-RS window associated with one or more CSI-RS, with respect to one or more mobility related measurements. The UE may determine one or more mobility related measurements using the CSI-RS configuration, and measure the one or more CSI-RS using the determination of the one or more mobility related measurements. The UE may generate a report for the base station corresponding to the measurement of the one or more CSI-RS.

Abstract: Apparatuses, systems, and methods for beam indication latency reduction via symbol level beam sweeping capability reporting. A wireless device may transmit, to a base station, a report associated with symbol level beam sweeping. The wire wireless device may receive, from the base station, a symbol level beam sweeping configuration. The symbol level beam sweeping configuration may be based, at least in part, on the report. The wireless device may perform synchronization signal block (SSB) measurements according to the report and the symbol level beam sweeping configuration.
