Abstract: Systems and methods are described for a resource allocation and user multiplexing capacity enhancements for interlace based physical uplink control channel (PUCCH) formats in new radio (NR) using unlicensed spectrum (NR-U). The systems and methods can include at least generating, by the UE, an uplink signal according to a physical uplink control channel (PUCCH) format 2 and having “n” number of physical resource blocks (PRBs) that are mapped in an interlaced manner across a frequency domain on a orthogonal frequency division multiplexing (OFDM) symbol, wherein “n” is an integer multiple of a number of PRBs per interlace, and transmitting, by the UE, the uplink signal over a PUCCH that utilizes unlicensed spectrum in a new radio wireless network.

Abstract: Systems, devices, and techniques for listen-before-talk (LBT) operations in unlicensed spectrum are described. A described technique includes receiving, by a user equipment (UE), a downlink control information (DCI) message, the DCI message including available bandwidth information and a channel occupancy time (COT) duration, the available bandwidth information being associated with one or more LBT bandwidths of a bandwidth part (BWP) in unlicensed spectrum; receiving, by the UE, one or more physical downlink shared channel (PDSCH) transmissions in the BWP, during the COT duration; and processing the one or more PDSCH transmissions based on the available bandwidth information.

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: Embodiments of a User Equipment (UE), Next Generation Node-B (gNB) and methods of communication are generally described herein. A channel state information (CSI) report may include a CSI part 1 transmission and may be configurable to include a CSI part 2 transmission. The UE may determine a first number of coded modulation symbols per layer to be used for the CSI part 1 transmission on a physical uplink shared channel (PUSCH) without uplink shared channel (UL-SCH) data. The first number of coded modulation symbols per layer may be determined as: a minimum of a first term and a second term if the CSI report includes the CSI part 2 transmission; and the second term if the CSI report does not include the CSI part 2 transmission.

Abstract: Embodiments of the present disclosure describe methods, apparatuses, storage media, and systems for determining that a first physical uplink control channel (PUCCH) resource and a second PUCCH resource at least partially overlap, where the first PUCCH resource has a payload of a first size carrying a first uplink control information (UCI) in a first format, and the second PUCCH resource has a payload of a second size carrying a second UCI in a second format. Furthermore, the first UCI and the second UCI are multiplexed to form a combined payload to be carried by the first PUCCH resource in the first format or by the second PUCCH resource in the second format. Other embodiments may be described and claimed.

Abstract: New radio (NR) Uplink (UL) transmissions in an NR physical UL channel can be configured for a user equipment (UE) to communicate with a base station (e.g., gNB). The structures and mechanisms for configured these communications different from long term evolution (LTE) in NR specifications. A UE can generate a UL transmission with symbols on the NR physical channel including demodulation-reference signal (DM-RS) symbols and uplink control information (UCI) symbols. The UL transmissions comprise a DM-RS symbol located at each first symbol with variable lengths. The UE generates the UL transmission as an NR physical UL channel with about a 50% DM-RS overhead with a same or more DM-RS symbols than UCI symbols in a sequential pattern (e.g., an alternating pattern). The UE further maps HARQ-ACK feedback on a PUSCH based a frequency first operation that initiates following the DM-RS symbol located at the first symbol.
