Abstract: A device may use sidelink request and sidelink response (e.g., DSS/STS and DRS) resources (in a sub-band) of different sizes depending on whether the sub-band is a primary sub-band or secondary sub-band. The device may transmit more information in the request/response resources of a primary sub-band than in the request/response resources of a secondary sub-band. The device may transmit small amounts of information in its request/response resources in secondary sub-bands. The resources in the secondary sub-bands may include, for example, reference signals, and signals indicating occupation of the sub-band. The device may utilize tone signaling for request/response signaling in the secondary sub-bands (at least because the amount of information being conveyed in the secondary sub-bands is small) and digital signaling in the primary sub-band (at least because the amount of information being conveyed in the primary sub-band is large in comparison to that being conveyed in the secondary sub-bands).

Abstract: A user equipment (UE) may determine that a synchronous transmission by the UE includes traffic having a priority higher than a priority of nominal traffic. In response to the determination, the UE may, alter a use of at least some of an initial portion of a discovery frame from energy detection to signal transmission. The signal transmission may be a pilot signal transmission or a non-information-carrying signal transmission. The traffic having the priority higher than the nominal traffic may include mission-critical traffic. A reliability requirement of mission-critical traffic may be higher than a reliability requirement of nominal traffic. A latency requirement of mission-critical traffic may be lower than a latency requirement of nominal traffic. The signal transmission may be at a power level that is sufficient to result in energy detection at another UE. Various additional and alternative aspects are described herein.

Abstract: In an aspect of the disclosure, a method, a computer program product, and an apparatus are provided. The apparatus may be a first node. The first node determines a data frame based on synchronization information. The data frame has a signaling block and a plurality of data slots. The signaling block is prior to the plurality of data slots. The first node communicates with a second node in the signaling block to reserve a first data slot of the plurality of data slots during which to transmit or to receive a first packet. The first node transmits the first packet to the second node or receives the first packet from the second node during the first data slot.

Abstract: The present disclosure provide various methods, computer-readable media, and apparatuses for managing communication paths, which may include at least one direct communication path between UEs, such as a sidelink communication path. Illustratively, an apparatus of the present disclosure may be a UE or component thereof that is configured to establish a direct wireless communication link and an indirect wireless communication link with another UE to carry data associated with one traffic stream. Further, the apparatus may be configured to communicate with the other UE over at least one of the direct communication link or the indirect communication link after the direct communication link and the indirect communication link are established with the other UE.

Abstract: Systems, methods, and devices for wireless communication that support resource selection and indication for sidelink demodulation reference signal (DMRS) bundling. A transmitting UE determines sidelink resources for bundling a sidelink DMRS transmission to be transmitted to a receiving UE. In sidelink mode 1, the sidelink resources may be determined based on indications from a base station, which may include whether the transmitting UE is to maintain phase continuity over the sidelink resources during the bundling, or whether the transmitting UE is to include a phase jump reference signal with the bundled DMRS transmission to the receiving UE. In sidelink mode 2, the transmitting UE may select the sidelink resources based on the phase continuity capabilities of the transmitting UE and/or of the receiving UE, and/or based on a sensing of the sidelink channel. In some cases, the receiving UE may provide a resource recommendation to the transmitting UE.

Abstract: Methods, systems, and devices for wireless communications are described. A network node may transmit a set of reference signals via a corresponding set of antennas, each antenna in the corresponding set of antennas associated with a unique precoding vector, wherein each precoding vector uses a combinational codeword based on a combination of codewords from a set of available codewords. The network node may receive, from an energy harvesting (EH)-capable device, a set of frequency-shifted backscatter responses corresponding to at least a subset of the set of reference signals. The network node may transmit, to the EH-capable device, a signal based on channel state information, wherein the channel state information is based on the set of frequency-shifted backscatter responses.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a transmit (Tx) user equipment (UE) may receive, from a base station, downlink control information (DCI) that triggers sidelink channel state information (CSI) reporting from a receive (Rx) UE to the Tx UE. The Tx UE may transmit, to the Rx UE, a request for CSI based at least in part on the DCI received from the base station. The Tx UE may receive, from the Rx UE, a CSI report based at least in part on the request. The Tx UE may transmit, to the base station, the CSI report received from the Rx UE. Numerous other aspects are described.

Abstract: Aspects relate to techniques for facilitating sidelink cancellation. A network entity, such as a base station, may schedule a sidelink transmission between a transmitting wireless communication device and a receiving wireless communication device and transmit scheduling information for the sidelink transmission to at least the transmitting wireless communication device. The network entity may further transmit control information including a cancellation indication to at least the transmitting UE. The cancellation indication may indicate at least an overlap between a portion of the resources allocated to the sidelink transmission and an additional transmission. Based on the cancellation indication, the transmitting wireless communication device may modify the sidelink transmission.
