Abstract: A first apparatus may be configured to generate a scheduling request to request to transmit at least one of data or control information on a sidelink channel. The first apparatus may be further configured to transmit, to another UE, the scheduling request on resources of a channel configured to carry feedback responsive to transmissions on the sidelink channel. A second apparatus may be configured to monitor resources on a channel for transmissions from other UE, the channel being configured to carry feedback from the other UE responsive to transmissions on a sidelink channel. The second apparatus may be further configured to receive at least one scheduling request from at least one of the other UE on the resources of the channel configured to carry the feedback based on monitoring the resources on the channel.

Abstract: Methods, systems, and devices for wireless communications are described. A transmitting device may transmit a polling request to a receiving device in sidelink control information that is associated with a sidelink data transmission. The polling request may be included in a sidelink control information message or in a medium access control layer message. The receiving device may respond to the polling request with an indication of whether there is data available for transmission to the transmitting device at the receiving device. The transmitting device may determine whether to schedule reverse sidelink resources for the receiving device to transmit the available data based on the response to the polling request.

Abstract: Methods, systems, and devices for wireless communication are described. In a system with high reliability and low latency targets, base station control can be dynamically configured. In some systems, a semi-static split with a greater duration for communications between a controller and one or more associated sensor/actuators than a duration for communications between the controller and base station can be used. In some embodiments, an interrupt can be used to allow for base station control.

Abstract: Certain aspects of the present disclosure provide techniques for autonomous reference signal transmission configuration. Certain aspects provide a method of receiving a configuration message from the base station, wherein the configuration message comprises an indication of a set of candidate resources for transmitting the reference signal. Certain aspects provide a method of detecting a future downlink transmission from the base station, and other aspects provide a method of transmitting, in response to detecting the future downlink transmission, the reference signal utilizing a first resource of the set of candidate resources prior to receiving the future downlink transmission via a second resource in the set of candidate resources.

Abstract: Methods, systems, and devices for wireless communication are described. Generally, the described techniques provide for efficiently performing and reporting reference signal received power (RSRP) measurements. In particular, the techniques described herein may allow a user equipment (UE) to efficiently identify reference signals on which to perform RSRP measurements (e.g., based on signaling from a base station), identify when to report RSRP measurements (e.g., aperiodically, periodically, or semi-persistently), and identify a channel on which to report RSRP measurements (e.g., a sidelink channel or an uplink channel). In addition, the techniques described herein may also allow a UE to efficiently identify open loop parameters to use to determine an appropriate transmit power for transmitting to another UE over a sidelink.

Abstract: Methods, systems, and devices for wireless communications are described that support resource utilization based event triggering. A wireless node in a wireless communications system may establish a connection with a core network via a path that includes one or more relay nodes. The wireless node may determine that a network load associated with one or more paths between the wireless node and the core network has changed, or that a difference between two or more network loads of different paths has changed. Based on such a determination, the wireless node may transmit a report to the network. In some cases, the network may receive the report from the wireless node, and may initiate a path change based on the report.

Abstract: Methods, systems, and devices for wireless communications are described. Autonomous transmissions between a user equipment (UE) and a base station may be configured that include at least one of a modulation and coding scheme (MCS) or resources for the transmissions. In some cases, a trigger may be detected that changes the MCS or resources to be used for the autonomous transmissions. The trigger may include the presence or absence of retransmissions or the value of a channel measurement falling below or exceeding a threshold value. Accordingly, the base station and UE may adjust the MCS or resources to be used for the autonomous transmissions based on detecting the trigger and then communicate using the adjusted MCS or resources. In some cases, the configuration for the autonomous transmissions may be signaled via a medium access control (MAC) control element (CE).

Abstract: Aspects of the disclosure relate to back-off mechanisms for fair joint access of an unlicensed sidelink channel. Each sidelink device may perform independent and asynchronous listen before talk (LBT) of the unlicensed sidelink channel with a respective back-off timer initialized with a back-off value selected to provide fair access to the unlicensed sidelink channel by both active sidelink devices and other devices utilizing the unlicensed sidelink channel. In some examples, the back-off value may be selected based on an estimated number of active sidelink devices. The estimated number of active sidelink devices may be determined, for example, by monitoring distributed handshake signaling on the unlicensed sidelink channel.

Abstract: Aspects of the present disclosure provide methods and apparatuses that can provide sidelink grant information to out-of-coverage (OoC) sidelink devices. When one or more sidelink devices are out of a coverage area of a base station, an in-coverage device receiving sidelink grant information from the base station can retransmit, relay, or rebroadcast sidelink grant information to the OoC sidelink devices to enable sidelink communication with the OoC device or facilitate sidelink communication between OoC devices.
