Abstract: Methods, systems, and devices for wireless communications are described. To improve sidelink reservation schemes. a first user equipment (UE) may indicate its preferences for sidelink resources to a second UE that may select sidelink resources for sidelink messages based on the indicated preferences. For example, the first UE may monitor a first set of sidelink resources for sidelink control information (SCI) to determine which sidelink resources of a second set of sidelink resources are available. Based on the monitoring, the first UE may generate a bitmap that indicates the first UE's preferences for the sidelink resources of the second set and may transmit a coordination message to the second UE that includes the bitmap. The second UE may receive the coordination message and transmit, to the first UE, one or more sidelink messages using one or more sidelink resources of the second set selected based on the indicated preferences.

Abstract: Disclosed are techniques for wireless positioning. In an aspect, a road-side unit (RSU) may join a first sidelink (SL) ranging session between a first user equipment (UE) and a second UE. The RSU may perform SL ranging with the first UE to determine first ranging information comprising at least a RTT to the first UE. The RSU may perform SL ranging with the second UE to determine second ranging information comprising at least a RTT to the second UE. The RSU may send the first ranging information and the second ranging information to at least one of the first UE or the second UE, or calculate a range between the first UE and the second UE based on the first ranging information and the second ranging information, and send the range to at least one of the first UE and the second UE.

Abstract: Methods, systems, and devices for wireless communications are described. A receiver user equipment (UE) may communicate with a transmitter UE in a sidelink channel to report a congestion index to the transmitter UE and/or additional transmitter UEs, where the transmitter UE(s) may then adjust one or more sidelink operation parameters based on the reported congestion index. In some cases, the transmitter UE may report the congestion index to an upper layer, to other transmitter UEs, to application layers, or a combination thereof. The transmitter UEs 115 and/or application layer may then adjust one or more sidelink transmission operation parameters based on the reported congestion index. For example, the transmitter UEs and/or application layer may adjust threshold values to lessen a number of retransmissions and lessen congestion.

Abstract: Methods, systems, and devices for wireless communications are described. For example, a base station may receive, from a first user equipment (UE), an uplink message that includes one or more sidelink communication identifications each associated with a different UE of a set of one or more UEs and may associate each of the one or more sidelink communication identifications with a corresponding second identification also associated with each of the set of one or more UEs. The base station may transmit one or more signals for transitioning each of the set of one or more UEs associated with the set of second identifications from an inactive mode to an active mode based on associating each of the set of one or more sidelink communication identifications with the second identification of the set of second identifications. A second UE may receive, while in the inactive mode from the base station, the one or more signals that trigger the transition and may communicate with the first UE based on receiving the wake-up signal.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may determine whether sufficient resources are available to perform a transmission in a current slot. The UE may transmit the transmission in the current slot, transmit an early reservation signal for a future resource, or determine whether sufficient resources are available to perform the transmission in a subsequent slot based at least in part on a probability-based determination and based at least in part on whether sufficient resources are available to perform the transmission in the current slot. Numerous other aspects are provided.

Abstract: Methods, systems, and devices for wireless communications are described. A first user equipment (UE) may be associated with a reconfigurable surface for reflecting transmissions between second and third UEs (e.g., over sidelink resources). In one example, the first UE may transmit signaling indicating that retransmissions of a first message transmitted between a second and third UE and detected by the first UE may be reflected by the reconfigurable surface associated with the first UE. In another example, the first UE may receive a request from a second UE for signal enhancement using a reconfigurable surface, the request associated with a future transmission by the second UE to a third UE. In either case, the UE may determine to perform signal enhancement using a reconfigurable surface and may then reconfigure the reconfigurable surface for reflecting transmissions or retransmissions from the second UE to the third UE.

Abstract: Disclosed are techniques for wireless communication. In an aspect, a transmitter user equipment (UE) determines a first zone identifier (ID) corresponding to a first zone in which the transmitter UE is located, determines a distance threshold based on a distance requirement of an application associated with the transmitter UE, determines a second zone ID based on the first zone ID, the distance threshold, a size of the first zone, or any combination thereof, and transmits the second zone ID and the distance threshold to one or more receiver UEs. In an aspect, the receiver UE receives the second zone ID and the distance threshold, determines a distance between the receiver UE and the transmitter UE based on the second zone ID and a location of the receiver UE, and transmits, based on the distance being less than the distance threshold, a feedback message to the transmitter UE.

Abstract: The present disclosure relates to dynamic antenna array reconfiguration and signaling in millimeter wave bands. A user equipment (UE) may detect an antenna array change condition. The UE may transmit a request for beam training for an antenna array configuration in response to the detecting. The request for beam training may include a requested antenna array configuration for the UE and an indication of beam weights to use with the requested antenna array configuration. A base station may determine whether to grant or deny the requested antenna array configuration for the UE. The UE may receive, from the base station, an indication of an antenna array configuration for the UE. The base station may transmit the number of reference signals as a set of contiguous channel state information reference signals (CSI-RS). The UE may train the reconfigured active antenna array configuration based on the reference signals.

Abstract: Methods, systems, and devices for wireless communication are described. A user equipment (UE) may utilize priority levels associated with packets or transmissions to determine whether to transmit feedback for a received transmission. The UE may compare priority levels between a transmission subject to a feedback condition and a transmission scheduled to be received when the feedback is scheduled to be transmitted to determine whether to send the feedback. The UE may communicate with the transmitting device according to the comparison and the determining. The UE may determine signal conditions causing a NAK and determine to send the NAK based on the signal conditions.
