Abstract: A user equipment (UE) includes a receiver configured to receive, during operation based on a first mode, a configuration message from a base station. The configuration message indicates sidelink resources associated with a sidelink data channel. The UE further includes a transmitter configured to transmit, based on detecting that one or more conditions associated with the configuration message are satisfied, and during operation based on a second mode, a sidelink message to a second UE via the sidelink data channel during an occasion associated with the sidelink resources.

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: Methods, systems, and devices for wireless communications are described for block feedback of multiple semi-persistent scheduling (SPS) occasions. Block feedback may be provided based on variable feedback timing values that are associated with one or more SPS occasions. A user equipment (UE) may determine feedback for each of two or more SPS occasions, and transmit a block feedback that indicates the feedback. A separate feedback timing between a SPS occasion and uplink feedback resources may be provided for multiple SPS occasions, which are associated with a single uplink feedback resource. Alternatively, a minimum feedback timing value and a maximum feedback timing value may be configured for a particular uplink resource, and block feedback for multiple SPS occasions within the minimum and maximum feedback timing values may be reported in the uplink feedback resource.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may determine candidate resources on one or more physical sidelink shared channels (PSSCHs) that are clear for transmitting at least two transport blocks, based at least in part on sensing a plurality of subchannels on the one or more PSSCHs with respect to listen-before-talk completion instants for the at least two transport blocks. The UE may select, from among the candidate resources, transmit resources on the one or more PSSCHs for transmitting the at least two transport blocks such that the at least two transport blocks are transmitted in one of: different subchannels of a same slot, or contiguous slots of a same subchannel. The UE may transmit the at least two transport blocks in the transmit resources. Numerous other aspects are provided.

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.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a first wireless communication device may detect that an antenna of a second wireless communication device is to perform a channel sensing procedure on a channel during a time occasion. The first wireless communication device may transmit, during the time occasion in one or more directions other than a direction of the antenna of the second wireless communication device, a signal that satisfies an energy detection threshold. Numerous other aspects are described.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a first wireless communication device may receive a configuration associated with reporting delta channel state information (CSI). The first wireless communication device may compute the delta CSI based at least in part on the configuration, the delta CSI indicating a difference between first CSI associated with a first connection and second CSI associated with a second connection, the first connection being between the first wireless communication device and a base station and the second connection being between the first wireless communication device and a second wireless communication device. The first wireless communication device may transmit, based at least in part on the configuration, a CSI report including an indication of the delta CSI and at least one of an indication of the first CSI or an indication of the second CSI. Numerous other aspects are described.

Abstract: Methods, systems, and devices for wireless communications are described. A first and second user equipment (UE) may perform a handshake procedure to establish a cooperation agreement designating one or more frequency and time resources which the first UE is to act as the proxy device for the second UE. For example, the first UE may receive a sidelink message directed to a second UE from a third UE. The first UE may determine to act as a proxy device for the second UE with respect to the sidelink message based on the sidelink message being received during a time resource designated for the first UE to act as the proxy device for the second UE. The first UE may proceed to transmit to the third UE feedback information associated with the sidelink message, and may transmit the sidelink message to the second UE on behalf of the third UE.

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.
