Abstract: An apparatus and system of supporting simultaneous physical uplink control channel (PUCCH) and physical uplink shared channel (PUSCH) transmission are described. A user equipment (UE) that supports service types with different priority levels is configured by a 5th generation NodeB (gNB) to multiplex transmissions with different priorities on different serving cells in different bands. The UE multiplexes and prioritizes high priority (HP) and low priority (LP) uplink transmissions with and without simultaneous PUCCH and PUSCH transmissions based on repetition and scheduling request (SR).

Abstract: An apparatus and system for deferring hybrid automatic repeat request (HARQ) feedback for semi-persistent scheduling (SPS) physical downlink shared channel (PDSCH) transmissions in a time-domain duplexing (TDD) system are described. After an SPS PDSCH configuration indicating that deferral of the SPS HARQ feedback is enabled is received, a user equipment (UE) determines whether a PUCCH associated with a particular SPS PDSCH transmission is able to be transmitted on valid uplink (UL) symbols. The PUCCH carries a SPS HARQ-ACK bits to acknowledge the particular SPS PDSCH transmission. If the PUCCH is unable to be transmitted using the timing of the SPS PDSCH configuration, the transmission is deferred until the next valid occasion on which the PUCCH is able to be transmitted.

Abstract: A user equipment (UE) configured for carrier frequency operations above 52.6 GHz may decode radio-resource control (RRC) signalling received from a gNodeB (gNB) to configure the UE with a number of resource blocks (RBs) (NRB) for a physical uplink control channel (PUCCH) resource for each of one or more enhanced PUCCH formats. The one or more enhanced PUCCH formats may include enhanced PUCCH format 0, enhanced PUCCH format 1 and enhanced PUCCH format 4. The number of RBs may be configurable to be more than one for the enhanced PUCCH format 0, the enhanced PUCCH format 1 and the enhanced PUCCH format 4. The UE may encode an enhanced PUCCH format for transmission in accordance with one of the enhanced PUCCH format 0, the enhanced PUCCH format 1 and the enhanced PUCCH format 4. The enhanced PUCCH format may be transmitted to occupy the number of RBs that are configured.

Abstract: A generation Node B (gNB) configured for operating in a fifth generation (5G) system encodes a downlink control information (DCI) for transmission to a user equipment (UE). For slot-less operation the DCI may indicate a set of values for a data channel scheduling gap and hybrid automatic repeat request—acknowledgement (HARQ-ACK) timing. The set of values may be defined for a symbol group including one or more symbols. The gNB may encode the data channel for transmission based on the one or more values. The data channel may be transmitted on the symbol group with slot-less operation and using a subframe or frame for reference timing.

Abstract: Various embodiments herein provide techniques to operate wideband (WB) cells, and in particular, WB operation for New Radio-Unlicensed (NR-U). The embodiments herein provide more accurate and efficient operation of WB procedures with listen-before-talk (LBT) operation as compared with existing and/or previous solutions. In embodiments, a user equipment (UE) may receive configuration information for a search space set that includes multiple monitoring locations in a frequency domain within a listen-before-talk (LBT) bandwidth part (BWP). The UE may monitor for a physical downlink control channel (PDCCH) on one or more of the monitoring locations

Abstract: An apparatus of a Fifth Generation NodeB (gNB) to operate in a License Assisted Access (LAA) system configures a transmission initiation time interval contention window size (CWS) of N number of subframes between Category 4 Listen Before Talk (LBT) uplink (UL) transmissions by a user equipment (UE) operating in the LAA system, and a memory to store a value of N which can have a value 6 or greater or 10 or greater. An apparatus of a UE to operate in an LAA system decodes a configuration from the gNB of a transmission initiation time interval contention CWS of N number of subframes between Category 4 LBT UL transmissions in the LAA system. The CWS is increased to a next higher value when an UL grant or an autonomous UL (AUL) downlink feedback indicator (DFI) is not received before the expiration of a timer.

Abstract: User equipment (UE) includes processing circuitry, where to configure the UE for New Radio (NR) communications in an unlicensed spectrum, the processing circuitry is to decode radio resource control (RRC) signaling including configuration information identifying a physical downlink control channel (PDCCH) search space set. The configuration information includes a PDCCH monitoring periodicity, a PDCCH monitoring offset, and a PDCCH monitoring duration associated with the PDCCH search space set. The PDCCH search space set is monitored for downlink control information (DCI) using the PDCCH monitoring periodicity, the PDCCH monitoring offset, and the PDCCH monitoring duration. Upon detecting the DCI within the monitored PDCCH search space set, a DCI format within the DCI is decoded.

Abstract: Various embodiments herein provide techniques related to hybrid automatic repeat request (HARQ) feedback of a new radio (NR) sidelink (SL) transmission. Specifically, in embodiments, a user equipment (UE) may perform, in a first slot of a plurality of slots, a listen before talk (LBT) procedure related to a NR SL transmission. The UE may further identify a subset of two or more candidate slots of the plurality of slots for transmission of a HARQ message related to the LBT procedure. The UE may further transmit the HARQ message in a candidate slot of the two or more candidate slots. Other embodiments may be described and/or claimed.

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.
