Abstract: Aspects relate to direct current (DC) tone indication on the sidelink A wireless communication device (e.g., a UE) may transmit an indication of its sidelink DC tone to one or more other UEs via respective sidelinks. In an example, a transmitting UE may transmit an indication of its sidelink DC tone within second stage sidelink control information included within a data region of a slot. A receiving UE may further transmit an indication of its sidelink DC tone to a transmitting UE over a sidelink between the transmitting UE and receiving UE or a base station in wireless communication with the transmitting and receiving UEs may provide the indication of the sidelink DC tone of the receiving UE to the transmitting 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: The present disclosure provides systems, methods, and apparatuses for grouping beams that are directionally associated with one another and associating respective properties associated with groups of beams. In one aspect, a UE or component thereof may be configured to select a first beam group of one or more beam groups to include a first beam of a set of beams, with the first beam group including a first subset of beams of the set of beams that is directionally associated with a first direction of the first beam. The UE or component thereof may be further configured to associate a respective set of properties with each of the one or more beam groups. The UE or component thereof be configured to communicate via the first beam of the first beam group of the one or more beam groups.

Abstract: Methods, systems, and devices for wireless communications are described. A first user equipment (UE) may receive control information from a network entity. The control information may indicate one or more sidelink resources allocated to the first UE for sidelink communications. The first UE may also receive an indication from the network entity that use of downlink power control parameters in determination of a sidelink transmission power for the sidelink communications may be disabled at the first UE. The first UE may transmit a sidelink message to a second UE using at least one sidelink resource of the one or more sidelink resources and with the sidelink transmission power determined at the first UE in accordance with the indication.

Abstract: Disclosed are techniques for wireless communication. In an aspect, a target user equipment (UE) receives, from a relay UE over a sidelink channel between the target UE and the relay UE, downlink control information (DCI) for a communication session between the target UE and a network entity, wherein the sidelink channel indicates search space information for a physical downlink control channel (PDCCH) between the target UE and the network entity carrying the DCI, and communicates with the network entity using a resource allocation granted by the DCI for a physical downlink channel, a physical uplink channel, or both between the target UE and the network entity based on the DCI and the search space information.

Abstract: Network-controlled power control for side-link communications is disclosed. According to the described aspects, a power control framework is defined for network-controlled side-band or device-to-device (D2D) communications, in which transmission power for side-link communications may be stepped up enough for a base station in a connected mode with at least one of multiple user equipment (UE) devices to detect side-link communications between the UEs in order to take responsive action to enhance the reliability of the communications. The base station provides the configuration information to the UEs which may be used when preparing for transmissions of side-link traffic and/or feedback.

Abstract: A base station may instruct a UE to use at least one weighting factor associated with a CR for the UE, and the UE may apply the at least one weighting factor to the one or more resources scheduled for the PSSCH transmission to determine the CR. The UE may transmit the PSSCH in the one or more resources of the at least one slot based on the determined CR being less than or equal to a CR threshold value. The at least one weighting factor may be applied to the one or more resources in each of multiple slots scheduled for transmission of a PSSCH.
