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.

Abstract: This disclosure provides systems, methods, and apparatuses, including computer programs encoded on computer storage media, for wireless communication, including techniques for sidelink resource allocation and communication. In some aspects, a user equipment (UE) may receive from a base station a single message that indicates a first transmission opportunity for transmission of information from the UE to a second UE and that indicates one or more additional transmission opportunities for at least one subsequent transmission of information from the UE to the second UE. The UE may transmit the information to the second UE in the first transmission opportunity. The UE may also retransmit the information to the second UE in at least one of the one or more additional transmission opportunities responsive to the transmission of the information in the first transmission opportunity being unsuccessful. Other aspects and features are also claimed and described.
