Abstract: Aspects presented herein relate to methods and devices for wireless communication of an apparatus, e.g., a UE. In one aspect, the apparatus may detect at least one conflict in a set of reserved resources between two or more sidelink (SL) resource reservations, each of the two or more SL resource reservations being associated with each of two or more UEs. The apparatus may also configure at least one of an indication of the at least one conflict or at least one resource reservation forwarding message. The apparatus may also transmit, after detecting the at least one conflict in the set of reserved resources, one or more of at least one resource reservation forwarding message or an indication of the at least one conflict.

Abstract: Certain aspects of the present disclosure to techniques for sidelink re-discovery without repeating beamforming in millimeter wave (e.g., Frequency Range 2) bands. For example, a Tx UE may complete a first beam training with a Rx UE. The Tx UE may generate a discovery message that includes at least one of: an indication of a beam training reference signal (BT-RS) sequence index of the first beam training; an indication of a timer for changing the BT-RS sequence; or an indication of a second BT-RS sequence to be used by the Tx UE before an expiration of the timer. The second BT-RS sequence may be indicated as an index to a set of BT-RS sequences including the BT-RS sequence associated with the first beam training. The Tx may transmit the generated discovery message to the Rx UE.

Abstract: An apparatus (e.g., a third UE) may be configured to detect at least one SPS conflict in a set of REs between a first SL (e.g., an SPS-based) transmission associated with a first UE and a second SL transmission associated with a second UE. The third UE may further be configured to transmit, upon detecting the SPS conflict, an indication of the SPS conflict to at least one of the first and second UEs. A first UE may be configured to receive, from the third UE, the indication of the SPS conflict, the indication of the SPS conflict including information regarding a set of resources associated with the detected conflict. The first UE may be further configured to initiate a resource re-selection for the first SL transmission based on the received indication and to transmit the first SL transmission based on the resource re-selection.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a transmitting user equipment (UE) (Tx UE) may receive a co-channel coexistence sidelink configuration for identifying and selecting a sidelink resource of a first network based, at least in part, on whether the sidelink resource of the first network occurs during a subframe of a sidelink resource of a second network. The Tx UE may transmit a sidelink message to a receiving UE in accordance with the co-channel coexistence sidelink configuration. Numerous other aspects are described.

Abstract: Methods, systems, and devices for wireless communications are described. User equipment (UE) may communicate sidelink coordination messages to indicate potential interference and select sidelink resources. For example, a first UE may transmit a sidelink coordination message to a second UE that includes a set of identifiers associated with a set of UEs. The second UE may select a first set of sidelink resources for a first sidelink communication with the first UE based on a reference signal received power (RSRP) of the sidelink coordination message and a reservation of a second set of sidelink resources for a second sidelink communication between the first UE and third UE of the set of UEs. For example, the second UE may determine the reservation, select the first set to be non-overlapping a time domain with the second set based on the RSRP, and perform the second sidelink communication with the first UE.

Abstract: A user equipment (UE) can transmit first radio access information indicating a first ratio of first sidelink devices configured to use a first radio access technology (RAT) to second sidelink devices configured to use a second RAT. The UE can receive second radio access information from one or more sidelink devices of at least one of the first sidelink devices or the second sidelink devices. Each second radio access information indicates a respective second ratio of the first sidelink devices configured to use the first RAT to the second sidelink devices configured to use the second RAT. The UE can select a resource pool frame structure based on the first ratio and each of the respective second ratios, and the resource pool frame structure is configured to partition a resource pool between the first RAT and the second RAT for sidelink communication in a sidelink network.

Abstract: Methods, systems, and devices for wireless communications are described. Generally, a user equipment (UE) may identify a set of time and frequency resources reserved by one or more second UEs for one of sidelink transmissions by the one or more second UEs to the first UE or to one or more third UEs (e.g., type A), or sidelink transmissions by the first UE to one or more third UEs (e.g., type B), and may select a first indicator and a second indicator for the reservation. The first indicator of a time resource and the second indicator of a frequency resource may be associated with the identified set of time and frequency resources for the reservation. The UE may transmit a coordination message that includes the first indicator and the second indicator, and includes an indication that the message is associated with type A or type B reservations.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive one or more signals associated with a sidelink channel to perform sensing of the sidelink channel. The UE may transmit a control signal associated with a first radio access technology (RAT) to reserve a set of resources associated with a resource pool for the sidelink channel based at least in part on the sensing of the sidelink channel, wherein at least one of the set of resources or the resource pool is associated with a second RAT. The UE may transmit, using one or more resources from the set of resources, a first sidelink message, wherein the first sidelink message is associated with the second RAT. Numerous other aspects are described.

Abstract: A first user equipment (UE) receives sidelink resource reservation information over sidelink from one or more UEs. The first UE transmits inter-UE coordination information in a sidelink transmission based on a probability threshold being met. A wireless device may receive one or more of a status of a UE, a capability of the UE, or a report. The wireless device may configure the UE with a probability threshold for transmission of inter-UE coordination information in a sidelink transmission.

Abstract: A first UE and at least one second UE are disclosed. The first UE may identify one or more resources that are suitable for a subsequent transmission from at least one second UE. The first UE may transmit to the at least one second UE, an inter-UE coordination message and at least one data transmission. The inter-UE coordination message may be transmitted at a same time as the at least one data transmission. The inter-UE coordination message may include an indication of the one or more resources that are suitable for the subsequent transmission from the at least one second UE. In one configuration, the inter-UE coordination message may be piggybacked with the at least one data transmission. The at least one second UE may transmit the subsequent transmission via the one or more resources, or may reselect the one or more resources based on the inter-UE coordination message.
