Abstract: Systems, methods, and circuitries are provided for configuring and indicating channel state information resource signals (CSI-RS) using discovery reference signal (DRS) resources. An example method includes determining discovery reference signal (DRS) resources for use in carrying channel state information reference signals (CSI-RS); generating CSI-RS configuration information that defines at least one CSI-RS using the DRS resources; and signaling the CSI-RS configuration information to a user equipment (UE) device.

Abstract: Systems and methods of providing timing information for initial access in an unlicensed band are described. A UE monitors a new radio discovery signal (NRDS-U) window in an unlicensed band for a DRS transmission that is constrained to be transmitted within the NRDS-U window. The UE determines initial access information, including an offset that indicates when the DRS transmission occurs within the NRDS-U window, and engages in initial access dependent on the offset. The offset is from a radio frame or half radio frame boundary or the start of the NRDS-U window. The offset is indicated in three least/most significant bits an SSB index or from an sl-offset field in a MIB of the SSB. When the base station uses a DFS channel, the base station transmits a periodic signal to emulate a radar signal.

Abstract: The present disclosure provides systems and methods for mapping transmission configuration indication (TCI) states to demodulation reference signal (DMRS) ports groups in a wireless network. For instance, a TCI state to DMRS ports group mapping of a user equipment (UE) can be determined. Each DMRS port in a DMRS ports group shares a quasi-co-location (QCL) assumption. The TCI state to DMRS ports group mapping comprises multiple TCI state groups. The TCI state to DMRS ports group mapping corresponds each TCI state group to one or more DMRS ports groups. A TCI state group from the DMRS ports group mapping can be selected for the UE. Data indicative of the selected TCI state group and the corresponding one or more DMRS ports groups can be provided to the UE based at least in part on the TCI state group from the DMRS ports group mapping.

Abstract: Systems, devices, and techniques for wireless communications are described. A described technique includes receiving, by a user equipment (UE) from one or more Transmission and Reception Points (TRPs), a physical downlink shared channel (PDSCH) transmission; determining, by the UE for a physical uplink control channel (PUCCH) carrying hybrid automatic repeat request-acknowledgement (HARQ-ACK), a TRP index in accordance with a control resource set (CORESET) scheduling the PDSCH transmission; and transmitting, by the UE via the PUCCH, HARQ-ACK information based on the receiving of the PDSCH transmission in accordance with the TRP index.

Abstract: Systems and methods for determining channel raster(s) and synchronization signal raster(s) for New Radio (NR) unlicensed spectrum are disclosed herein. For each of a plurality of data objects an NR channel raster position is determined using Absolute Radio Frequency Channel Number (NR-ARFCN) numbers. For each corresponding NR channel. Global Synchronization Channel Numbers (GSCNs), a number of Physical Resource Blocks (PRBs) based on channel subcarrier spacing (SCS). NR channel raster position placement, channel edges, synchronization signal and physical broadcast channel (SSB) edges, and an SSB raster position are calculated. The plurality of data objects may then be down selected based on e.g., corresponding Long Term Evolution (LTE) channel raster positions and/or entries of a second plurality of data objects calculated for NR channels that use a second SCS.

Abstract: User equipment (UE) includes processing circuitry coupled to memory. To configure the UE for multi-transmission reception point (TRP) reception, the processing circuitry is to decode radio resource control (RRC) signaling. The RRC signaling includes configuration information configuring a plurality of transmission configuration indication (TCI) states. A media access control (MAC) control element (CE) is decoded, where the MAC CE indicates multiple active TCI states of the configured plurality of TCI states. Multiple received beams are determined using the multiple active TCI states. Downlink information is decoded, where the downlink information originates from multiple TRPs and is received via the determined multiple receive beams associated with the multiple active TCI states.

Abstract: Systems, apparatuses, methods, and computer-readable media are provided for an access point (AP) for a wireless communication system operating in a licensed and an unlicensed spectrum. The AP includes processor circuitry configured to determine a plurality of interleaved interlaces based on a bandwidth of a physical uplink channel and a subcarrier spacing (SCS). The processor circuitry is configured to identify a plurality of resource blocks (RBs) corresponding to a first interleaved interlace of the plurality of interleaved interlaces, which are based on a number of subcarrier per RB. The processor circuitry is configured to allocate the plurality of RBs corresponding to the first interleaved interlace among one or more user equipments (UEs), and generate an indication of the allocated plurality of RBs, the first interleaved interlace, and the one or more UEs to transmit to the one or more UEs via radio front end circuitry coupled to the processor circuitry.
