Abstract: Methods, systems, and devices for wireless communications are described. In some cases, a first user equipment (UE) may transmit, to a second UE, first control information indicating a first transmission configuration indicator (TCI) state for use in sidelink communications between the first UE and the second UE. The first UE may receive, from the second UE, second control information indicating a second TCI state for use in sidelink communications between the first UE and the second UE, where a first application time of the first TCI state conflicts with a second application time of the second TCI state. The first UE may select, in accordance with one or more rules for resolving sidelink TCI state conflicts, one of the first TCI state or the second TCI state as a selected TCI state. Accordingly, the first UE may communicate with the second UE in accordance with the selected TCI state.

Abstract: Methods, systems, and devices for wireless communications are described. In some examples, a user equipment (UE) may receive, from a base station, a configuration indicating a set of occasions configured for sidelink communications for the UE. The sidelink communications may include at least one of sidelink traffic, semi-persistent scheduling traffic, or a combination thereof. The UE may receive a control indication associated with a radio network temporary identifier. The control indication may include a downlink control information. In some examples, the UE may skip a first pre-scheduled occasion of the set of occasions configured for sidelink communications based on the control indication, and may perform sidelink communications during a second pre-scheduled occasion of the set of occasions after skipping the first pre-scheduled occasion.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may transmit, to a network entity, a first message indicating data collected at the first UE and geo-location information of the first UE. The first UE may receive, from the network entity, a second message indicating a sidelink grant for transmitting a sidelink message on a set of resources and a source identifier and destination identifier associated with the sidelink message. The first UE may transmit the sidelink message on the set of resources to at least a second UE, the sidelink message including the source identifier and the destination identifier. The second UE may transmit, to the network entity, an indication of calculated geo-location information for the first UE and a received power measurement of the sidelink message based on the sidelink message.

Abstract: Certain aspects of the present disclosure provide techniques for uplink transmissions through sidelinks for multi-path diversity. A method that may be performed by a base station (BS) includes configuring one or more groups of user equipments (UEs) of a group of UEs with a configuration of one or more resources. The one or more resources includes one or more sidelink channels between each of the UEs in the group of UEs and an uplink channel between the BS and each of the UEs in the group of UEs. The BS receives data from at least one UE in the group of UEs via at least one of the uplink channels, wherein the data is associated with a different UE.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may measure, for a first beam group of a set of beam groups associated with the UE, a first channel busy ratio (CBR) for the first beam group. The UE may receive, from a second UE, an indication of a second CBR for a second beam group associated with the second UE. The UE may transmit, to the second UE using a beam included in the first beam group, a signal using one or more transmit parameters that are based at least in part on at least one of the first CBR or the second CBR. Numerous other aspects are described.

Abstract: In some aspects of the disclosure, an apparatus for wireless communication includes a receiver and a transmitter. The transmitter is configured to transmit a first transmission during a first time slot and to transmit a second transmission during a second time slot that is after the first time slot. The first transmission includes first data and a first demodulation reference signal (DMRS) associated with the first data, and the second transmission includes second data and a second DMRS associated with the second data. One or more of the first transmission or the second transmission further includes an indication of whether a joint channel estimation operation is to be performed based on the first DMRS and the second DMRS.

Abstract: Certain aspects of the present disclosure provide techniques for a fallback retransmission for a sidelink. A method that may be performed by a user equipment (UE) includes monitoring a transmission from a node. The UE can determine that the transmission was not successfully decoded. The UE can send a feedback message to the node indicating that the transmission was not successfully decoded. The feedback message can also include an indication of whether the node or a base station (BS) retransmits the transmission. The node retransmits the transmission or indicates to the BS to retransmit based on the feedback message. The BS can configure the node, the UE, or both with one or more thresholds for determining whether the node or the BS retransmits the transmission.

Abstract: Apparatus, methods, and computer-readable media for facilitating indicating cancelation of transmissions of sidelink messages are disclosed herein. An example method for wireless communication at a sidelink device includes transmitting SCI reserving a set of resources for one or more retransmissions of a message, the set of resources identifying one or more reserved resources in a time domain. The example method also includes identifying a skipped transmission associated with one or more of the set of resources reserved by the sidelink device. Additionally, the example method includes transmitting a cancelation indication indicating the skipped transmission, the cancelation indication indicating that the skipped transmission corresponds to a previous reserved resource in the time domain, a current reserved resource in the time domain, or a future reserved resource in the time domain.

Abstract: Methods, systems, and devices for wireless communications are described. In one example, a first user equipment (UE) identifies a trigger condition associated with a first communication link with a base station and establishes a second communication link with a second UE. The UE may transmit a relay request to the second UE based on the trigger condition, wherein the relay request instructs the second UE to relay communications for the first UE. The first UE communicates with the base station via the second communication link. In another example, a base station establishes communication links with a first and second UE. The base station receives a data forwarding request that instructs the base station to use the second UE to relay communications between it and the first UE. The base station communicates with the first UE via the second communication link based at least in part on the relay request.
