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: A user equipment (UE) may receive information, via radio resource control (RRC) signaling, regarding a search space of a physical downlink control channel (PDCCH) for obtaining downlink control information (DCI) from a radio access network (RAN) node. Based on a slot format (SF) index in the DCI, the UE may determine a slot format for communicating with the RAN node, and communicate with the RAN node in accordance with the slot format. Additionally, a UE may communicate UE capability information, which may include a maximum number of blind decode attempts (BDAs), to the RAN node. The UE may determine 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), obtain sDCI by monitoring the sPDCCH in accordance with the determined sCCEs, and communicate with the RAN node in accordance with the sDCI.

Abstract: Some embodiments of this disclosure include apparatuses and methods for a fallback procedure for a 2-step random access channel (RACH) procedure for data transmission in a wireless communication system where the apparatuses and methods include at least generating, by a user equipment (UE), a first signal that includes a first message (MsgA) for a 2-step random access channel (RACH) procedure, transmitting, by the UE, the first signal to a next generation NodeB (gNB), determining, by the UE, whether a 4-step RACH procedure is to be used to further transmit the first signal including the MsgA, and further transmitting, by the UE, the first signal to the gNB using the 4 step RACH procedure based on determining that the 4-step RACH procedure should be used.

Abstract: Embodiments of a User Equipment (UE), Generation Node-B (gNB) and methods of communication are disclosed herein. The UE may receive a physical downlink control channel (PDCCH) that schedules a physical downlink shared channel (PDSCH) in a slot, and on a component carrier (CC) of a plurality of CCs. The PDCCH may include a total downlink assignment index (DAI) and a counter DAI for hybrid automatic repeat request acknowledgement (HARQ-ACK) feedback of the PDSCH. The total DAI may indicate a total number of pairs of CCs and slots for the HARQ-ACK feedback. The UE may encode the HARQ-ACK feedback to include a bit that indicates whether the PDSCH is successfully decoded. A size of the HARQ-ACK feedback may be based on the total DAI, and a position of the bit may be based on the counter DAI.

Abstract: Described are mechanisms and methods for supporting Channel State Information (CSI) measurement and reporting, and for supporting Radio Resource Management (RRM) measurement and reporting, under License Assisted Access (LAA) with dynamic power sharing. An eNB may comprise one or more processors to generate a maximum number of Component Carriers (CCs) and a number of active CCs to a UE. The eNB may then be operable to process a reported quality rating from the UE and generate a scaled quality rating based upon the reported quality rating, the maximum number of CCs, and the number of active CCs. A UE may comprise one or more processors to process a reference signal transmission from an eNB, to generate an unfiltered reference signal transmission based upon the reference signal transmission, and to calculate a quality rating based upon the unfiltered reference signal transmission.

Abstract: Devices and methods of reducing overall Hybrid Automatic Repeat Request-Acknowledgment (HARQ-ACK) of user equipment (UE) using a large amount of carrier aggregation are generally described. The UE may receive a subframe from an enhanced NodeB (eNB). The subframe may contain a physical downlink control channel (PDCCH) formed in accordance with a Downlink Control information (DCI) format. The DCI format may comprise a Downlink Assignment Index (DAI) for Time Division Duplexed (TDD) and Frequency Division Duplexed (FDD) operation. The UE may determine, dependent on the DAI, a number and ordering of Hybrid Automatic Repeat Request-Acknowledgment (HARQ-ACK) bits to be transmitted on a Physical Uplink Shared Channel (PUSCH) and subsequently transmit the HARQ-ACK bits.

Abstract: Technology for a user equipment (UE) operable for configured grant uplink (UL) transmission in new radio unlicensed (NR-U) is disclosed. The apparatus can comprise one or more processors. The one or more processors can be configured to select, at the UE, a hybrid automatic repeat request process identifier (HARQ process ID) from a set of HARQ IDs. The one or more processors can be configured to insert the HARQ process ID into uplink control information (UCI) on a physical uplink shared channel (PUSCH). The one or more processors can be configured to encode, at the UE, the UCI for transmission to a next generation node B (gNB) via a configured grant uplink transmission using the HARQ process ID.
