Abstract: The apparatus may be a first UE. The first UE may determine a first set of candidate BPLs associated with a first SL and a second set of candidate BPLs associated with a second SL. The first UE may further determine a configuration for FD beam training based on the determined first set of candidate BPLs and the determined second set of candidate BPLs, the FD beam training configuration may include multiple instances for which the first UE transmits and receives RS at a same time. The apparatus may also select, based on the determined FD beam training configuration, a first BPL in the first set of candidate BPLs for the first SL and a second BPL in the second set of candidate BPLs for the second SL. The first UE may establish FD communication with the second UE based on the selected first BPL and the selected second BPL.

Abstract: Methods, systems, and devices for wireless communications are described. For instance, a first user equipment (UE) may identify a configuration for an assisting node (AN) that includes an indication of a set of time resources during which the AN is active and an indication of location information that indicates communication direction information corresponding to communications via the AN during the set of time resources. The first UE may select a time resource from the set of time resources based on the indication of location information, a location of the first UE, and information associated with a packet for transmission from the first UE to a second UE via the assisting node. The first UE may transmit the packet over the selected time resource.

Abstract: Methods, systems, and devices for wireless communications are described. A first user equipment (UE) may establish multiple unicast connections with multiple other UEs. The first UE may then determine individual sets of transmission parameters for each of the multiple other UEs, where the individual sets of transmission parameters may enable the first UE to receive transmissions from the multiple other UEs on a same set of time and frequency resources via a spatial division multiplexing scheme. For example, each of the individual sets of transmission parameters may include a transmission schedule adjustment, a transmit power, a transmit time, an indication of the time and frequency resources, or a combination thereof. The first UE may then transmit each of the individual sets of transmission parameters to a respective UE of the multiple other UEs.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a receiving (Rx) user equipment (UE) may receive, from a transmitting (Tx) UE, sidelink control information (SCI). The Rx UE may determine an Rx-side block error rate (BLER) based at least in part on the SCI. The Rx UE may perform a beam failure recovery based at least in part on the Rx-side BLER satisfying a threshold. Numerous other aspects are described.

Abstract: Methods, systems, and devices for wireless communications are described. The method may include monitoring a resource group of a sidelink channel for an indication of sidelink messaging traffic, determining a ratio of sidelink messaging traffic by a first radio access technology relative to sidelink messaging traffic by a second radio access technology based on the monitoring, selecting, based on the ratio, a first resource pattern of a set of multiple different resource patterns, and communicating, via the sidelink channel, a first sidelink message within a first resource of the resource group in accordance with the first resource pattern.

Abstract: Methods, systems, and devices for wireless communications are described. To improve sidelink reservation schemes, a first user equipment (UE) may receive, from a second UE, a coordination message indicating a set of resources associated with sidelink communications and a preference of the second UE for one or more subsets of the set of resources. The first UE may transmit the sidelink communications using one or more resources of the set of resources based on the preference of the second UE for the one or more subsets of the set of resources. In some examples, the one or more resources may be selected from candidate resources within a resource selection window of the first UE. Additionally, or alternatively, the candidate resources may be based on the preference of the second UE.

Abstract: Methods, systems, and devices for wireless communication are described. A user equipment (UE) may receive control signaling indicating a co-channel configuration. The co-channel configuration may indicate a set of sidelink parameters for a co-channel operation associated with dynamically utilizing sidelink radio frequency resources allocated for a first radio access technology and sidelink radio frequency resources allocated for a second radio access technology. The UE may transmit, based on the received co-channel configuration, an indication of a set of channel availability parameter values indicating an amount of available sidelink radio frequency resources associated with the first radio access technology, the second radio access technology, or both. Subsequently, the UE may receive a grant scheduling a set of sidelink resources for the wireless communication associated with the second radio access technology based on the transmitted indication of the set of channel availability parameter values for the co-channel operation.

Abstract: Methods, systems, and devices for wireless communications are described. A first user equipment (UE) sense sidelink transmissions to determine a set of resources that may be reserved by one or more other UEs. The set of resources may include a first subset of resources associated with a first radio access technology (RAT) and a second subset of resources associated with a second, different RAT. The first UE may transmit a message to a second UE indicating resource information for transmissions by the second UE, and the resource information may indicate that the first subset of resources is associated with the first RAT and that the second subset of resources is associated with the second RAT. Additionally, or alternatively, the first UE may transmit an indication of collisions between resources reserved for transmissions associated with the first RAT and resources reserved for transmissions associated with the second RAT.
