Abstract: Aspects described herein relate to preempting or cancelling sidelink or uplink resources of one or more devices to allow sidelink or uplink transmissions of one or more other devices, and/or determining subsequent resources for transmitting communications based on the preempted or cancelled sidelink or uplink resources. In an aspect, an indication to preempt receiving communications or cancel transmitting communications over scheduled resources can be received, and based at least in part on the indication, subsequent resources over which to receive or transmit the communications can be determined. The communications can be received or transmitted in the subsequent resources.

Abstract: Aspects relate to obtaining, at a first scheduled entity, a first priority ranking of first uplink (UL) data scheduled for transmission to a scheduling entity and a first data scheduled for transmission to a second scheduled data, as well as a second priority ranking of second data scheduled for transmission to a third and fourth scheduled entity, respectively. The scheduling uses at least a portion of a sidelink resource reserved for sidelink communication for the transmissions. The scheduling of the transmissions using at least the portion of the sidelink resource are based on the first priority ranking and the second priority ranking. Various transmission cancellation and reception preemptions are transmitted from transmitting scheduled entities to other transmitting or receiving scheduled entities, respectively. Such cancellations and preemptions are based on the priority rankings, prediction of data transmission collisions and prediction of interference at receiving entities.

Abstract: A configuration for inter-cell interference coordination in wireless communication systems. The apparatus determines a priority order of a first base station to schedule a first transmission with a first UE. The apparatus transmits a first transmission request to the first UE to schedule the first transmission. The apparatus receives, from the first UE, a measurement report based on the first transmission request received by the first UE, the measurement report indicates a signal quality of the first transmission request. The apparatus determines to schedule the first transmission with the first UE based at least on the measurement report. The apparatus sends a schedule indication to at least a second base station indicating whether the first transmission is scheduled with the first UE, at least the second base station has a lower priority order than the first base station.

Abstract: A user equipment (UE) determines a beam failure of a default uplink beam for the UE. The UE transmits an uplink beam failure report in response to determining the beam failure of the default uplink beam, the uplink beam failure report indicating that a reported beam is the default uplink beam for the UE. A base station receives an uplink beam failure report from the UE and determines that a reported beam is a default uplink beam for the UE.

Abstract: Aspects of the present disclosure provide apparatus, methods, processing systems, and computer readable mediums for a UE to provide an indication when the quality of a group of previously-reported simultaneously receivable transmit beams has degraded to the point they are no longer simultaneously receivable.

Abstract: Aspects of the present disclosure provide techniques for interference coordination between wireless nodes (e.g., nodes of an Integrated Access and Backhaul (TAB) network). The techniques generally include determining, by a first wireless node, resources for sending an indication of interference coordination to a second wireless node, and sending the indication to the second wireless node using the determined resources, as part of an interference coordination procedure.

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: Certain aspects of the present disclosure provide techniques for selecting and indicating a quasi colocation (QCL) source signal for sidelink (SL) communications. For example, a scheduling node may select from multiple candidates a signal for a first user equipment (UE) to use as a spatial QCL source for a receive (RX) or transmit (TX) beam to use for communicating with a second UE on a SL interface. The scheduling node may then signal the first UE an indication of the selection of the signal.

Abstract: A method, a computer-readable medium, and an apparatus are provided for wireless communication including random access between a base station and a user equipment (UE). The UE transmits at least two first random access messages (Msg 1) to multiple transmission reception points (TRPs) of at least one cell using different resources for the multiple TRPs. The UE monitors for at least two second random access messages (Msg 2) from the multiple TRPs of the at least one cell using different resources for the multiple TRPs.

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.
