Abstract: This disclosure provides systems, devices, apparatus, and methods, including computer programs encoded on storage media, for a sidelink coverage extension using repeated transmission. A first UE may transmit a multiple slot SCI in a first slot of a group of multiple slots for reserving resources for the group of multiple slots and transmitting one or more sidelink transmissions in the reserved resources. A second UE may receive the multiple slot SCI in the first slot of the group of multiple slots for receiving the one or more sidelink transmissions in the reserved resources for the group of multiple slots. In aspects, a base station may receive configuration parameters for the multiple slot SCI and configure one or more UEs with a multiple slot configuration, based on the configuration parameters, for transmitting/receiving the multiple slot SCI associated with the reserved resources in the group of multiple slots.

Abstract: Methods, systems, and devices for wireless communications are described. In one aspect, a first user equipment (UE) may transmit an indication of non-preferred resources to a second UE and an indication of an amount of transmit power reduction for the second UE to observe for a sidelink transmission on the non-preferred resources. In another aspect, a first UE may transmit an indication of an amount of transmit power reduction for a second UE to observe for a sidelink transmission on conflicting resources (e.g., resources reserved by the second UE and a third UE). Because the second UE may transmit on the non-preferred resources or the conflicting resources with reduced power (e.g., rather than suppressing transmissions on the non-preferred resources or the conflicting resources), the utilization of the non-preferred resources or the conflicting resources may be improved.

Abstract: This disclosure provides systems, devices, apparatus, and methods, including computer programs encoded on storage media, for UE feedback of non-preferred time-frequency resources. The UE may receive, from a base station over time, a plurality of DL transmissions for which the UE may perform measurements on the plurality of DL transmissions. Based at least in part on the measurements, the UE may transmit, to the base station, an indication of a set of one or more time-frequency resources to avoid using for communications with the UE.

Abstract: Methods, systems, and devices for wireless communication are described. Generally, the described techniques provide for forward/retransmitting a data transmission to a target UE through a helper UE. A helper UE may receive a data transmission from a network node, determining whether the received data transmission is intended for a target UE or for the helper UE itself, based on a control message, and retransmitting the data transmission to the target UE upon determining that the data transmission is intended for the target UE. A network node such as a base station may transmit a control message to at least a help UE, the control message comprising an indicator of whether a data transmission is intended for the helper UE or a target UE and transmit the data transmission to at least the helper UE and the target UE.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may measure, using one or more beams included in a first beam group associated with the UE, a channel occupancy ratio (CR) for the first beam group. The UE may perform an action if the CR for the first beam group does not satisfy a CR limit associated with the first beam group. Numerous other aspects are described.

Abstract: Disclosed are techniques for determining tone patterns for transmission of reference signals. One or more parameters associated with communications with a base station over a time duration, may be determined by a user equipment. The user equipment may determine, based on the one or more parameters, a tone pattern for a reference signal for use in communications with the base station over a future time duration. The user equipment may then transmit the tone pattern to the base station. The user equipment may then receive the reference signal from the base station, over the tone patterns.

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: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a wireless device may receive, for communications with one or more of a base station or another wireless device, information identifying that an uplink transmission on a sidelink and a downlink transmission on a sidelink are to precede an uplink transmission on an access link and a downlink transmission on an access link. The wireless device may communicate, with the one or more of the base station or the other wireless device, based at least in part on the information identifying that the uplink transmission on the sidelink and the downlink transmission on the sidelink are to precede the uplink transmission on the access link and the downlink transmission on the access link. Numerous other aspects are provided.

Abstract: Certain aspects of the present disclosure provide techniques for group semi-persistent scheduling (SPS) for path diversity. A method that may be performed by a node includes configuring one or more groups of user equipments (UEs) with one or more SPS resources. The node sends a downlink control information (DCI) to activate one of the SPS resources for one of the groups of UEs and transmits data to the group of UEs using the activated SPS resource. A first UE may receive data from the node using the activated SPS resource and retransmit the data to the second UE. The first helping UE and the second targeted UE may be identified based on the higher layer configuration with the SPS resources, based on information in the DCI, and/or based on information sent with the data.
