    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: 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: 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.
