Abstract: One innovative aspect of the subject matter described in this disclosure can be implemented in a method for wireless communication. The method includes determining a configuration of reference signal (RS) resources to be used by a user-equipment (UE) to perform beam measurements, transmitting, to the UE, an indication of the configuration of the RS resources, and receiving, from the UE, a report indicating a plurality of RS resource indicators based on the beam measurements, each of the RS resource indicators being associated with one of the RS resources. In some aspects, the BS selects a subset of the RS resources based on the report from the UE, transmits, to the UE, an indication to provide channel measurement information for the subset of the RS resources, and receives a report including the channel measurement information from the UE. The BS may also perform joint precoding of signals for transmission via the RS resources based on the channel measurement information.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may establish communications between the UE and a serving cell. The serving cell may be different than each non-serving cell of a set of non-serving cells for the UE. The UE may use machine learning models to determine outputs associated with mobility measurement reporting for the UE. The outputs may indicate whether to perform measurements associated with the set of non-serving cells, whether to report the measurements associated with the set of non-serving cells, one or more non-serving cells within the set of non-serving cells for performing or reporting the measurements, or one or more reference signals of the one or more non-serving cells for performing the measurements, or any combination thereof. The UE may perform the mobility measurement reporting based on the outputs.

Abstract: Disclosed are systems and techniques for wireless communications. In one example, a method for wireless communications performed at a first user equipment (UE) can include determining at least one active interference cancellation (AIC) area for protection during a sidelink communication. In some aspects, the method can include determining one or more frequency subcarriers associated with protection of the at least one AIC area during the sidelink communication, wherein transmission of the one or more frequency subcarriers is configured to reduce interference within the at least one AIC area.

Abstract: Methods, systems, and devices for wireless communications are described. During an operation for discovering reconfigurable surfaces, a sensing signal may be transmitted. Based on the sensing signal being transmitted, another signal may be detected at the device that transmitted the sensing signal, another device, or both. The device that detects the signal may combine the detected signal with a modulation sequence that is associated with a reconfigurable surface, where the reconfigurable surface may be assigned a set of unique modulation sequences and configured to apply a modulation sequence to received signals. Based on combining the detected signal with the modulation sequence, the device may determine whether the reconfigurable surface is present within a geographic region.

Abstract: Aspects described herein relate to establishing a control connection with at least a first node and a second node for receiving control information for providing a repeater function between two or more wireless nodes. Control information can be communicated over the control connection from one or more of at least the first node or the second node. The repeater can provide, based on the control information, the repeater function between the two or more wireless nodes. Other aspects relate to establishing a control connection with a first node for receiving control information for providing a repeater function for one or more upstream nodes, receiving control information over the control connection, determining a conflict in receiving the control information or a conflict within the control information for two or more upstream nodes, and providing, based on the control information and conflict, the repeater function for the one or more upstream nodes.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive an indication of a configuration to perform cooperative radar sensing. The configuration may indicate resources for the first UE to use to communicate radar measurement reports. The UE may receive, from another UE on the identified resources, a radar measurement report that includes values for one or more radar measurement parameters for a first radar target and a time stamp associated with the values. The UE may identify a second set of values for the radar measurement parameters (e.g., its own measurements, or measurements received from a third UE in another radar measurement reports). The UE may generate a combined set of values for the radar measurement parameters for each time stamp by combining the first set of values and the second set of values.

Abstract: Methods, systems, and devices for wireless communications are described. A wireless communications system may support tone reservation techniques in sidelink communications. A first user equipment (UE) may identify one or more subcarriers of a plurality of subcarriers, the one or more subcarriers associated with a tone reservation signal for sidelink. The first UE may select one or more symbols for transmitting the tone reservation signal on the one or more subcarriers. The first UE may transmit, to a second UE, sidelink signaling over the plurality of subcarriers, wherein the sidelink signaling includes the tone reservation signal over the one or more subcarriers during the one or more symbols. The second UE may receive the sidelink signaling and identify the tone reservation signal during the one or more symbols associated with the one or more subcarriers. The second UE may decode the sidelink signaling based on identifying the tone reservation signal.

Abstract: Methods, systems, and devices for wireless communication are described. A base station may transmit a paging indicator message to one or more user equipment (UEs) in a group of UEs. The base station may receive, based at least in part on the paging indicator message, a first response message from the one or more UEs. The first response message may be received using a resource that is shared with a random access channel message for the group of UEs. The base station may transmit, based at least in part on the first response message, a second response message to the one or more UEs.

Abstract: Methods, systems, and devices for wireless communications are described. Repetitions of a reference signal may be transmitted by a first device. In some examples, the repetitions may be quasi-colocated with one another, share an antenna port, or both. The repetitions of the reference signal may arrive at a reconfigurable surface. The reconfigurable surface may apply a modulation sequence to the repetitions of the reference signal and output modulated repetitions of the reference signal in a direction based on a reflective state of the reconfigurable surface. A signal including the modulated repetitions of the reference signal may be received by a second device and combined with the modulation sequence used by the reconfigurable surface to obtain a combined signal. The combined signal may be used to determine, for the reconfigurable surface, information about a channel between the first device and the second device.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a first user equipment (UE) may receive, from a second UE and via a receive beam of the first UE, an inter-UE coordination (IUC) request, wherein the IUC request is based at least in part on a transmit beam of the second UE that is associated with an intended transmission of the second UE. The UE may transmit, to the second UE, IUC information that indicates preferred resources or non-preferred resources for the intended transmission, wherein the IUC information is based at least in part on a channel sensing by the first UE. Numerous other aspects are described.
