Abstract: A base station receives feedback for a first data transmission or an indication to retransmit a first data transmission, the first data transmission being transmitted to at least one wireless device from another wireless device. The base station transmits, in response to the feedback or the indication, a retransmission of the first data transmission in a downlink transmission to the at least one wireless device.

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.

Abstract: Methods, systems, and devices for wireless communication are described. A first cell may receive a message indicating that a second cell has a priority transmission scheduled using a transmit time interval (TTI) that is shorter than a TTI used by the first cell. The first cell may limit, based on the message, a communication parameter associated with communications between the first cell and a user equipment (UE) during the scheduled priority transmission.

Abstract: Certain aspects of the present disclosure provide techniques for direct TB forwarding. In aspects, a relay node receives, from a source node, an indication to directly forward one or more TBs to one or more destination nodes, wherein directly forwarding includes transmitting a TB of the one or more TBs to the one or more destination nodes through only a PHY layer and a HARQ portion of a MAC layer in a protocol stack of the relay node, receives, from the source node, control information for one or more data channels configuring: one DL grant and two or more SL grants, or two or more DL grants and one SL grant, decoding one or more TBs based, at least in part, on the control information, and directly forwards the one or more TBs to the one or more destination nodes based on the indication and the control information.

Abstract: Enhanced measurements for new radio-unlicensed (NR-U) operations are disclosed. Compatible user equipments (UEs) may be configured to perform virtual full listen before talk (LBT) procedures for measurement purposes. The UEs may then compile LBT statistics derived from the virtual LBT procedures and include such statistics in an enhanced measurement report the their serving base stations. The LBT statistics provide a more direct and detailed reflection of the usage of a shared communication channel. Such UEs may further be configured to gather additional LBT statistics from transmission-based LBT procedures in addition to the virtual LBT procedures. The additional direct and detailed usage of a shared channel may then be provided in the enhanced measurement reports in accordance with described aspects.
