Abstract: An apparatus of a user equipment (UE) includes processing circuitry, where to configure the UE for New Radio (NR) communications above a 52.6 GHz carrier frequency, the processing circuitry is to decode higher layer signaling, the higher layer signaling including a default slot duration for a transmission of control signaling. The control signaling includes a synchronization signal (SS) and a physical broadcast channel (PBCH) signaling. Synchronization information within a SS block is decoded. The SS block is received within a SS burst set and occupying a plurality of symbols within a slot having the default slot duration. A synchronization procedure is performed with a next generation Node-B (gNB) based on the synchronization information within the SS block and the PBCH signaling.

Abstract: An apparatus of user equipment (UE) includes processing circuitry coupled to a memory, where to configure the UE for DMRS processing in an NR network, the processing circuitry is to decode higher layer signaling, the higher layer signaling to indicate whether transform precoding is enabled and to indicate a modulation scheme for a physical uplink shared channel (PUSCH) if transform precoding is enabled. A set of low Peak-to-Average-Power-Ratio (PAPR) base sequences of length-6 is generated. A reference signal sequence is generated as a demodulation reference signal (DMRS) using the set of low-PAPR base sequences, based on the modulation scheme if transform precoding is enabled by the higher layer signaling, the modulation scheme being a π/2-binary phase-shift keying (BPSK) modulation scheme. Mapping of the DMRS to physical resources for transmission using the PUSCH is performed.

Abstract: Systems, apparatuses, methods, and computer-readable media are directed to techniques for codebook support for different antenna structures, such as a user equipment (UE) with a non-uniform antenna array (e.g. with different distances between antenna elements) and/or multiple antenna panels. Embodiments further provide techniques for enhanced operation in full power mode 2. For example, embodiments provide techniques for antenna virtualization to form virtual antenna ports from subsets of transmit antennas of the UE (e.g., from eight transmit antennas to two, four, or six virtual antenna ports). Other embodiments may be described and claimed.

Abstract: A generation node B (gNB) configured for aperiodic channel state information reference signal (CSI-RS) triggering and transmission may encode signalling for transmission to a user equipment (UE). The signalling to indicate an aperiodic Triggering Offset (aperiodicTriggeringOffset). The aperiodic Triggering Offset may comprise a slot offset. The gNB may encode a downlink control information (DCI) for transmission that may trigger transmission of a CSI-RS in one or more aperiodic CSI-RS resource set(s) (i.e., in one or more slots (n)). The DCI triggers transmission of the aperiodic CSI-RS within a triggered slot with the slot offset (i.e., the aperiodicTriggeringOffset). The gNB may transmit the CSI-RS in resource elements of the triggered slot in accordance with the slot offset, when CSI-RS resources are available in the slot at the slot offset. The gNB may postpone transmission of the aperiodically triggered CSI-RS to a first available downlink slot when the CSI-RS resources are not available in the triggered slot at the slot offset.

Abstract: Various embodiments herein provide techniques for reference signal (RS) configuration for high frequency bands (e.g., frequency above 52.6 GHz). For example, embodiments may include techniques for configuration of a demodulation reference signal (DM-RS), a channel state information reference signal (CSI-RS), and/or a sounding reference signal (SRS). The RS configuration may provide a low peak-to-average power ratio (PAPR) compared to prior techniques. Other embodiments may be described and claimed.

Abstract: A computer-readable storage medium stores instructions to configure a UE for a power control procedure in a 5G NR and beyond wireless network. The instructions cause the UE to perform operations including decoding RRC signaling received from a base station. The RRC signaling includes one or more open-loop power control parameters. A reference signal received power (RSRP) is determined. The RSRP is associated with a reference signal received from the base station using a receive beam. A path loss associated with the receive beam is determined based on the RSRP. A transmission (Tx) power is determined using the one or more open-loop power control parameters and the path loss. The Tx power is adjusted based on a power threshold shared between at least two antenna panels of a plurality of antenna panels. Uplink data is encoded for transmission to the base station according to the adjusted Tx power.

Abstract: Systems and methods for transmission of PDSCH and HARQ-ACK feedback in 5G networks are described. The TDRA of PDSCH repetitions are indicated in a DCI by a SLIV sequence configuration that contains multiple SLIV sequences. Each SLIV sequence for a slot is associated with an independent repetition factor and may also be associated with a partition factor to indicate a partition within the slot. One or more TRPs may be used to transmit each PDSCH repetition. The TCI states are mapped to the PDSCH repetitions in a round-robin fashion using an offset in terms of number of PDSCH repetitions from where TCI state switching starts and a number of consecutive PDSCH repetitions per TCI state. The HARQ-ACK bits in response to the PDSCH from the TRPs are concatenated in order of increasing control resource set higher layer signaling index.
