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: A network device (e.g., a user equipment (UE), or a new radio NB (gNB)) can process or generate a configuration of a physical random access channel (PRACH) over physical resource blocks (PRBs) that are interlaced in an unlicensed band in an NR unlicensed (NR-U) communication. The PRBs in the PRACH can be based on an occupied channel bandwidth (OCB) of the unlicensed band in the NR-U communication. A random access channel transmission in the PRACH can then be generated by interlacing the PRBs defining the PRACH.

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: 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: 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: Technology for a user equipment (UE), operable for monitoring a physical downlink control channel (PDCCH) is disclosed. The UE can monitor a downlink (DL) control channel for DL control information (DCI) at a predetermined monitoring occasion, wherein the predetermined monitoring occasion has a periodicity of P slots or P symbols with an offset Os. The UE can monitor a downlink (DL) control channel for DL control information (DCI) at a predetermined monitoring occasion, wherein Os has an offset with respect to a first slot in subframe number zero (SFN #0). The UE can monitor a downlink (DL) control channel for DL control information (DCI) at a predetermined monitoring occasion, wherein P is a positive integer greater than zero.

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.
