Abstract: Technology for a Next Generation NodeB (gNB) operable to encode a primary synchronization signal for transmission to a user equipment (UE) is disclosed. The gNB can identify a sequence d(n) for a primary synchronization signal. The sequence d(n) can be defined by: d(n)=1−2s(n), where s(n) is a maximum run length sequence (m-sequence) and s(n) is provided as s(n+7)=(s(n+4)+s(n))mod 2, where 0≤n≤127. The gNB can generate the primary synchronization signal based on the sequence d(n). The gNB can encode the primary synchronization signal for transmission to the UE.

Abstract: A user equipment (UE) may include one or more processors that are configured to cause UE capability information to be communicated to a radio access network (RAN) node, regarding a maximum number of blind decode attempts (BDAs) supported by the UE. The one or more processors are configured to determine, based on the maximum BDAs, shortened channel control elements (sCCEs) to be used, by the RAN node, to transmit shortened downlink control information (sDCI) via a shortened physical downlink control channel (sPDCCH) and obtain sDCI by monitoring the sPDCCH in accordance with the determined sCCEs.

Abstract: Techniques are described relating to hybrid automatic repeat request acknowledgement (HARQ-ACK) feedback using a HARQ-ACK aggregation window. A User Equipment (UE) may receive control information (e.g., downlink control information (DCI) or radio resource control (RRC) signaling) from a base station including HARQ-ACK codebook information. The HARQ-ACK codebook information may include information on a size of a HARQ-ACK aggregation window. The UE may decode physical downlink shared channel (PDSCH) transmissions and encode corresponding HARQ-ACK feedback using the HARQ-ACK aggregation window based on the control signaling.

Abstract: An apparatus of user equipment (UE) includes processing circuitry coup led to a memory, where to configure the UE for radio link monitoring (RLM) in a New Radio-Unlicensed (NR-U) network, the processing circuitry is to decode radio resource control (RRC) signaling from a base station. The RRC signaling includes configuration information to configure transmission occasions for a plurality of RLM reference signals (RLM-RSs). A primary synchronization signal (PSS) or a secondary synchronization signal (SSS) detection is performed to determine a number of RLM-RSs of the plurality of RLM-RSs that are successfully transmitted during the transmission occasions. Signal measurements are performed on the RLM-RSs that are successfully transmitted within an evaluation duration to determine a block error rate (BLER). The signal measurements are performed when the number is higher than a threshold number. An in-sync (IS) indicator or an out-of-sync (OOS) indicator are generated based on the signal measurements.

Abstract: Technology for an apparatus of a user equipment (UE), operable to perform a random-access procedure using a UE-specific control resource set (CORESET) is disclosed. The UE can decode a 5 message, received from the next generation node B (gNB), to perform a contention free random-access (RA) procedure. The UE can encode a random-access channel (RACH) preamble for transmission to the gNB using one or more UE-specific CORESET. The UE can decode a random-access response (RAR) received from the gNB in response to the RACH preamble transmission using the one or more UE10 specific CORESET.

Abstract: Embodiments of a Generation Node-B (gNB), User Equipment (UE) and methods for communication are generally described herein. The gNB may map data symbols to resource elements (REs) of virtual resource blocks (VRBs). The gNB may interleave the data symbols, on a per-VRB basis, to spatial layers of a multi-layer multiple-input multiple-output (MIMO) transmission. The data symbols may be interleaved based on different interleave patterns of VRB indexes for the spatial layers. The gNB may map the interleaved data symbols of the spatial layers to REs of physical resource blocks (PRBs) for orthogonal frequency division multiplexing (OFDM) transmission.
