Abstract: Some embodiments of this disclosure include systems, apparatuses, methods, and computer-readable media for a shared channel occupancy time (COT) procedure in a wireless channel of unlicensed spectrum. The shared COT can be utilized among one or more user equipment (UE) and a 5G Node B (gNB). A UE contends for access to the channel to acquire the COT, and transmits in the uplink (UL) according to the UEs time-domain configuration. When the UL transmission does not utilize the entire COT, the UE can signal to the gNB that the COT can be shared. In particular, the UE transmits an indication of a COT boundary that the gNB can use to determine when to transmit DL data in the shared COT. The COT can also be shared between two or more UEs in addition to the gNB.

Abstract: Systems, methods, and apparatuses disclosed herein can perform uplink (UL) transmission in new radio (NR) systems operating on an unlicensed spectrum. These systems, methods, and apparatuses can receive a downlink (DL) signal comprising information associated with listen before talk (LBT) type. These systems, methods, and apparatuses can perform the UL transmission based on the LBT type.

Abstract: Systems, apparatuses, methods, and computer-readable media are provided for a wireless communication on an unlicensed spectrum. An access point (AP) of the wireless communication system includes a processor circuitry, and radio front end circuitry coupled to the processor circuitry. The processor circuitry is configured to schedule multiple transmission time intervals (multi-TTIs) in a physical uplink shared channel (PUSCH) in the unlicensed spectrum. The processor circuitry is configured to generate a downlink control information (DCI) to include the scheduled multi-TTIs and a hybrid automatic repeat and request acknowledgement (HARQACK) assessment information associated with the scheduled multi-TTIs. The radio front end circuitry is configured to transmit the DCI to a user equipment (UE) over the unlicensed spectrum.

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: 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: Some embodiments of this disclosure include systems, apparatuses, methods, and computer-readable media for use in a wireless network for grant based Physical Uplink Shared Channel (PUSCH) transmission and configured grant based PUSCH transmission in new radio systems operating in an unlicensed spectrum. Some embodiments are directed to a user equipment (UE) that includes processor circuitry and radio circuitry. The processor circuitry can be configured to receive using the radio circuitry, configuration data from a source device associated with a source cell, and determine based on the configuration data, a starting position and ending position for transmitting data in multiple slots in a PUSCH within a shared channel occupancy time (COT), where the starting position depends on a listen before talk (LBT) outcome. The processor circuitry can perform the LBT, and transmit using the radio circuitry, the data at the starting position in an available slot of the COT.

Abstract: Systems, apparatuses, methods, and computer-readable media are provided for a wireless communication system in an unlicensed spectrum. A user equipment (UE) device of the wireless communication system includes a processor circuitry and radio front end circuitry. The processor circuitry is configured to acquire a channel occupancy time (COT) in the unlicensed spectrum, and determine a number of remaining consecutive subframes allocated for physical uplink shared channel (PUSCH) transmission to a base station. The processor circuitry is configured to generate uplink control information (UCI) to indicate a COT sharing boundary occurring at an end of the remaining consecutive subframes. The radio front end circuitry is coupled to the processor circuitry and configured to transmit the UCI in the PUSCH) transmission during one of the remaining consecutive subframes. The processor circuitry is also configured to monitor downlink transmissions from the base station following the COT sharing boundary.

Abstract: Systems, apparatuses, methods, and computer-readable media are provided for a user equipment (UE) for a wireless communication system operating in a licensed spectrum and an unlicensed spectrum. The UE performs a listen before transmission (LBT) procedure to acquire a channel for an uplink (UL) transmission upon determination that a first LBT priority class of a first order of UL transmission is not less than a second LBT priority class of a second order of UL transmission, and a maximum channel occupancy time (MCOT) corresponding to the first order of UL transmission is at least a total length of the UL transmission comprising a first length of the first order of uplink (UL) transmission and a second length of the second order of UL transmission. In response to acquiring the channel, the UE performs the first order of UL transmission, followed by the second order of UL transmission.
