Abstract: Embodiments of a User Equipment (UE) to operate in accordance with a physical random access channel (PRACH) are disclosed herein. The UE may comprise hardware processing circuitry to determine a coverage enhancement category for the UE based on downlink channel statistics related to reception of downlink signals at the UE from an Evolved Node-B (eNB) and an uplink-downlink imbalance parameter related to uplink reception at the eNB. The hardware processing circuitry may be further to select, for use in a coverage enhancement mode, a PRACH preamble from a set of candidate PRACH preambles based on the determined coverage enhancement category for the UE. In some embodiments, at least some of the candidate PRACH preambles may span a different number of sub-frames.

Abstract: A UE configured for operating in a 5G NR network may decode signalling that schedules two physical downlink shared channels (PDSCHs) in a same time slot. When the UE is a reduced-bandwidth (RBW) reduced-capacity (RedCap) UE (RBW-RedCap UE), the UE may determine if a total number of allocated PRBs in an OFDM symbol for the two scheduled PDSCHs exceed a predetermined value when the two scheduled PDSCHs either partially or fully overlap in time in non-overlapping PRBs. The UE may also prioritize decoding of one of the two scheduled PDSCHs when the total number of allocated PRBs exceed the predetermined value and when the two scheduled PDSCHs either partially or fully overlap in time in non-overlapping PRBs. If a first of the two scheduled PDSCHs is a unicast PDSCH and a second of the two scheduled PDSCHs is a broadcast PDSCH, the UE may prioritize decoding of the unicast PDSCH.

Abstract: An apparatus and system of providing a listen before talk (LBT) procedure in multi-carrier or multi-beam mode above a 52.6 GHz band are described. The LBT procedure is performed independently for each carrier or beam to maintain and update a different back-off counter for each carrier or beam. To align a transmission starting time across the carriers or beams, for each carrier or beam: the counter continues to decrement if the counter has reached zero before the starting time and transmit at the starting time if the channel continues to be sensed idle for an additional observation period immediately prior to the starting time and otherwise considers the LBT procedure to have failed. The counter is reinitialized for carriers or beams for which a channel occupancy time (COT) is to be acquired and transmission ceases.

Abstract: A user equipment (UE) may determine one or more nominal time-domain windows (TDWs) for demodulation reference signals (DMRS) bundling for physical uplink control channel (PUCCH) transmissions of a PUCCH repetition. A start of a new actual TDW for the DMRS bunding is determined in response to an event which causes power consistency and phase continuity not to be maintained across the PUCCH transmissions of the PUCCH repetition. The UE may maintain power consistency and phase continuity within the new actual TDW across two PUCCH transmissions of the PUCCH repetition. The event may comprise a use of different power control parameters for the two of the PUCCH transmissions of the PUCCH repetition within one of the nominal TDWs.

Abstract: A computer-readable storage medium stores instructions to configure a UE for multi-cell scheduling in a 5G NR network, and to cause the UE to perform operations including decoding higher layer signaling. The higher layer signaling indicates a number of cell groups configured to the UE. Each cell group of the number of cell groups includes at least two cells. DCI received in a PDCCH is decoded. The DCI includes a scheduling grant with time and frequency allocation for a PUSCH or a PDSCH in the number of cell groups configured to the UE. Uplink data transmissions via the PUSCH are scheduled in the number of cell groups or downlink data receptions via the PDSCH are scheduled in the number of cell groups based on the scheduling grant.

Abstract: A user equipment (UE) configured for physical uplink shared channel (PUSCH) repetition in an fifth-generation (5G) new radio (NR) network decodes a downlink control information (DCI) format that includes a scheduling grant for a PUSCH transmission. For a codebook-based PUSCH transmission, the DCI format indicates at least a first and a second transmit precoder matrix indicator (TPMI) index for PUSCH repetition. The UE may apply a precoder matrix determined from the first TPMI index to encode a PUSCH for a first PUSCH transmission occasion of the PUSCH repetition and may apply a precoder matrix determined from the second TPMI index to encode the PUSCH for a second PUSCH transmission occasion. For a non-codebook-based PUSCH transmission, the DCI format indicates at least a first and a second sounding reference signal (SRS) resource indicator (SRI) for PUSCH repetition. The UE may apply the first SRI to encode the PUSCH for the first PUSCH transmission occasion and may apply the second SRI to encode the PUSCH for the second PUSCH transmission occasion.

Abstract: A computer-readable storage medium stores instructions to configure a UE for Reduced Capability (RedCap) operation in a 5G NR network, and to cause the UE to perform operations. The operations include decoding a master information block (MIB) to determine a control resource set (CORESET) and a common search space (CSS): decoding a system information block (SIB) in a physical downlink shared channel (PDSCH) scheduled by a downlink control information (DCI) format, the DCI format received based on the CORESET and the CSS: determining an additional CORESET within a separate initial DE BWP using the SIB: and performing reception of a physical downlink control channel (PDCCH) in a PDCCH Type1 Common Search Space (CSS) set or a PDSCH associated with Random Access (RA) procedure in the separate initial DE BWP.
