Abstract: Methods, systems, and devices are described for providing allocations and signaling for different types of communications within a wireless communication system. An eNB and/or a UE may be configured to operate within the wireless communication system using two or more different types of communications. The different types of communications may differ, for example, based on round trip time (RTT) between transmission and acknowledgment of receipt of the transmission, a transmission time interval (TTI) for wireless transmissions, and/or duty cycle timing of wireless transmissions. Reserved resources within a system bandwidth may be identified for a first type of communications, and all or a portion of remaining resources within the system bandwidth may be allocated for other communications that may differ from the first type of communications based on, for example, RTT, TTI, and/or duty cycle timing.

Abstract: Methods, systems, and devices for wireless communications are described that provide for frame-based initiator device operations. A wireless device may be operating within a frame-based equipment communications system, where a frame may include a channel occupancy time period and a minimum idle period. An initiating device may be configured to initiate autonomous uplink communications during the channel occupancy time period of its frame, while the device may not initiate communications during an idle period of its frame. In some cases, a frame-based equipment communications system may include more than one initiating device, where the idle periods for different initiating devices may occur at different times. In some cases, the initiating device may be configured to initiate communications during the idle period for another initiating device. This may allow the wireless system to decrease system overhead associated with a minimum idle period per frame.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may determine that an availability condition is satisfied, wherein the availability condition relates to an availability of the UE for sidelink communication; identify future available information (FAI) that indicates at least one of a time domain availability of the UE for sidelink communication or a frequency domain availability of the UE for sidelink communication; and transmit the FAI based at least in part on determining that the availability condition is satisfied. Numerous other aspects are provided.

Abstract: A method of wireless communication includes identifying, by a first node configured for operation in a synchronous communication mode, a current synchronization boundary according to a common clock of the synchronous communication mode. The method further includes performing, by the first node, a common clock-triggered (CCT) listen before talk (LBT) procedure of a shared communication channel during a periodic quiet interval at the current synchronization boundary. The method further includes establishing, by the first node, in response to success of the CCT LBT procedure, a channel occupancy time (COT) configured to end at a subsequent synchronization boundary and transmitting, by the first node, data on the shared communication channel during the COT.

Abstract: Methods, systems, and devices for wireless communication are described. A wireless device (base station or UE) may receive an indication of a listen before talk (LBT) gap for sharing a channel occupancy time (COT), the COT being acquired by another wireless device (base station or UE), and detect whether a slot within the COT is occupied by the other wireless device, the slot occurring prior to the LBT gap. The wireless device may also, responsive to detecting that the slot is occupied by the other wireless device, perform an LBT procedure during the LBT gap, and, responsive to a successful LBT procedure, transmit a signal to the other wireless device within the COT.

Abstract: Methods, systems, and devices are described for hierarchical communications and low latency support within a wireless communications system. An eNB and/or a UE may be configured to operate within the wireless communications system which is at least partially defined through a first layer with first layer transmissions having a first subframe type and a second layer with second layer transmissions having a second subframe type. The first subframe type may have a first round trip time (RTT) between transmission and acknowledgment of receipt of the transmission, and the second layer may have a second RTT that is less than the first RTT. Subframes of the first subframe type may be multiplexed with subframes of the second subframe type, such as through time division multiplexing. In some examples symbols of different duration may be multiplexed such that they different symbol durations coexist.

Abstract: Methods, systems, and devices for wireless communications are described. A base station may configure a user equipment (UE) with a multiple listen-before-talk (LBT) bandwidths, where each LBT bandwidth is associated with one or more downlink control channel candidates of a search space for a control resource set. The UE may monitor the LBT bandwidths during a wakeup signal period for a wakeup signal from the base station. The UE may be configured with a total number of blind hypotheses in the set of blind hypotheses which is equal to or greater than a total number of LBT bandwidths. The UE may determine whether to wake up and monitor an on duration of a discontinuous reception cycle based on detection of the wakeup signal.

Abstract: Certain aspects of the present disclosure provide techniques for qualifying machine learning model-based channel state information (CSI) predictions. An example method generally includes receiving, from a network entity, a channel state information (CSI) prediction model for quantized CSI, calculating CSI based on downlink reference signal measurements, generating a quantized CSI difference value based a quantization of a difference between the calculated CSI and CSI predicted based on a CSI prediction model, and reporting, to the network entity, the calculated CSI and the quantized CSI difference value.

Abstract: Methods and apparatuses are described in which an unlicensed spectrum is used for Long Term Evolution (LTE) communications. One method includes performing a clear channel assessment (CCA) for an unlicensed spectrum in a current gating interval to determine whether the unlicensed spectrum is available for a transmission in a next transmission interval, and gating OFF the transmission in the unlicensed spectrum for the next transmission interval when the determination is that the unlicensed spectrum is unavailable.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a node may identify a listen-before-talk (LBT) success time at which an LBT procedure, performed by the node, succeeds; determine a lag between the LBT success time and a most recent synchronization reference boundary that occurred prior to the LBT success time; and determine a maximum channel occupancy time for transmissions on an unlicensed radio frequency spectrum band based at least in part on comparing the lag and a threshold. Numerous other aspects are provided.
