Abstract: Some embodiments of this disclosure include systems, apparatuses, methods, and computer-readable media for use in a wireless network for time-domain resource allocation for configured grant transmissions in New Radio (NR) systems. For example, some embodiments are directed to an electronic device including radio front end circuitry and processor circuitry coupled to the radio front end circuitry. The processor circuitry can be configured to generate a radio resource control (RRC) signal including a bitmap for configuring time-domain resources for configured grant (CG) operation. The processor circuitry can be further configured to transmit, using the radio front end circuitry, the RRC signal to a user equipment (UE) to configure the time-domain resources. The bitmap comprises a plurality of resource units and wherein each resource unit in the plurality of resource units corresponds to a symbol, a

Abstract: Devices, systems and methods for a fifth generation (5G) or new radio (NR) system comprising determining a configuration for an uplink (UL) transmission resource with respect to a listen before talk (LBT) operation on an unlicensed spectrum and transmitting uplink control information (UCI) on the UL transmission resource based on the configuration subjected to the LBT operation.

Abstract: Systems, methods, and apparatuses disclosed herein can operate on an unlicensed spectrum. These systems, methods, and apparatuses can perform a first listen-before-talk (LBT) operation of a LBT protocol in a first slot from among multiple slots to determine whether the unlicensed spectrum is unoccupied. Thereafter, these systems, methods, and apparatuses can transmit an uplink (UL) transmission in other slots from among the plurality of slots in response to the unlicensed spectrum being unoccupied. Otherwise, these systems, methods, and apparatuses can perform a second LBT operation in a second slot from among the plurality of slots in response to the unlicensed spectrum being occupied.

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 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: Some embodiments of this disclosure include systems, apparatuses, methods, and computer-readable media for use in a wireless network for generating and using slot format indicator (SFI) and channel occupancy time (COT) structure in new radio (NR) systems operating on unlicensed spectrum. For example, some embodiments are directed to a base station that includes radio front end circuitry and processor circuitry. The processor circuitry can be configured to generate a slot format indicator (SFI) associated with a channel occupancy time (COT) structure. The SFI indicates whether one or more slots associated with the COT structure are to be used for downlink (DL) symbols, uplink (UL) symbols, or flexible symbols. The flexible symbols form one or more gaps in the COT structure in response to the flexible symbols not being overridden as a DL transmission or a UL transmission. The processor circuitry can further be configured to transmit the SFI to a user equipment (UE).

Abstract: Systems, apparatuses, methods, and computer-readable media are provided for use in a wireless network for resource allocation during initial access. Some embodiments are directed to an apparatus including processor circuitry and radio front circuitry. The processor circuitry can be configured to determine, in accordance with a predetermined requirement, multiple physical resource blocks (PRBs) to be used for transmitting a physical uplink control channel (PUCCH) before a dedicated PUCCH resource configuration. The radio front end circuitry coupled with the processor circuitry can be configured to transmit the PUCCH using the determined PRBs and before the dedicated PUCCH resource configuration. The dedicated PUCCH resource configuration can include initial access before Radio Resource Control (RRC) connection setup.
