Abstract: Methods, systems, and devices for wireless communications are described. Generally, a user equipment (UE) may estimate one or more channel availability parameter values. The UE may then select, based on a co-channel configuration indicating a relationship between channel availability parameter values and patterns of sidelink resources, a pattern of sidelink resources (e.g., LTE resources) on which to transmit NR packets. In some examples, a special UE may receive individual or aggregated reports of channel availability parameter values. The special UE may select a pattern of sidelink resources (e.g., LTE resources) on which one of the reporting UEs is permitted to transmit NR packets, and may transmit a message activating the pattern of sidelink resources to the reporting UE. The reporting UE may then use the activated sidelink LTE resources for transmitting NR packets according to the indicated pattern.

Abstract: Methods, systems, and devices for wireless communications are described. A first user equipment (UE) may reserve a set of sidelink resources for a first sidelink transmission. A detecting UE may identify a sidelink feedback channel collision arising from a first sidelink feedback transmission to a first UE and a second sidelink feedback transmission to a second UE sharing same feedback channel resources. The detecting UE may determine one or more UEs to transmit a sidelink feedback channel collision indication to, and transmit, the collision indication to the one or more UEs. The first UE may identify a collision involving the first sidelink feedback transmission associated with the first sidelink transmission and the second sidelink feedback transmission associated with a second sidelink transmission by the second UE. The first UE may determine to transmit or retransmit the first sidelink transmission based on the sidelink feedback channel collision being identified.

Abstract: A first wireless device may encode a plurality of first blocks into a plurality of second blocks based on a coding scheme. The plurality of second blocks may include redundancy information such that the plurality of first blocks is recoverable based on less than all of the plurality of second blocks if more than a threshold number of second blocks in the plurality of second blocks are decodable. The first wireless device may transmit the plurality of second blocks to a second wireless device. The second wireless device may recover the plurality of first blocks based on less than all of the plurality of second blocks.

Abstract: Apparatus, methods, and computer-readable media for sidelink control information forwarding for sensing procedure are disclosed herein. An example method of wireless communication at a forwarding user equipment (UE) includes receiving, from a forwarded UE, control information, and transmitting, to a sensing UE, a forward message including the control information and information associated with the forwarded UE. An example method of wireless communication at the sensing UE includes receiving, from the forwarding UE, a forward message including the control information containing a first measurement of the control information. The example method also includes obtaining a second measurement of the forward message and determining a ratio of the second measurement to the first measurement. The example method also includes selecting a specific resource based on the ratio and whether the forwarding UE is an intended receiver for the sensing UE or the forwarding UE intends to receive from the forwarded UE.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a transmitter user equipment (UE) may identify beamforming information for transmitting a pre-reservation signal that indicates a set of non-preferred resources associated with a data transmission. The UE may transmit, to a receiver UE in accordance with the beamforming information, the pre-reservation signal that indicates the set of non-preferred resources associated with the data transmission. Numerous other aspects are described.

Abstract: Aspects relate to dynamic resource sharing for sidelink communication. In some examples, a user equipment (UE) may modify a first sidelink transmission resource set associated with a first radio access technology (RAT) to exclude at least one resource indicated by a second sidelink transmission resource set associated with a second RAT. In some examples, a UE may prioritize certain transmissions. For example, a UE may drop a sidelink reception operation if there is a conflict with a sidelink transmission operation. In some examples, a UE may prioritize a particular RAT. For example, a UE may drop a sidelink transmission operation on a first RAT if there is a conflict with a sidelink transmission operation on a second RAT (e.g., the second RAT is deemed to have a higher priority).

Abstract: Methods, systems, and devices for wireless communications are described for shared radio frequency spectrum band access information. A sensing device may monitor one or more frequencies of the shared radio frequency spectrum band and may receive signaling indicating access information (e.g., automated frequency control information). The access information may indicate one or more frequencies of the shared radio frequency spectrum band that are accessible for the sensing device. The scheduling device may obtain the access information from an access point, local storage media, or the like. In some examples, the scheduling device may transmit signaling indicating the accessible frequencies based on a request message from the sensing device. The sensing device may receive the access information and may communicate on one or more of the indicated frequencies accordingly.

Abstract: Sidelink (SL) positioning of user equipments (UEs) is supported by providing with SL positioning reference signals (PRS) an indication of the identity of the SL positioning session and the SL PRS source identifier. A UE may transmit a payload-based indication or a sequence-based indication of the identity of the SL positioning session and the source identifier. The pay-load based indication is included in, e.g., a Layer 1 (L1) and/or Layer 2 (L2) control message associated with the SL PRS. The sequence-based indication may be generated using the indication of the identity of the SL positioning session and the source identifier to initialize or seed the generation of the PRS sequence, scramble the PRS sequence, or generate a cover code that is applied to the PRS sequence.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a first user equipment (UE) may transmit, to a second UE, a sidelink transmission that spans multiple aggregated slots, wherein a first symbol in a slot of the sidelink transmission enables a decoding of the sidelink transmission by the second UE. The first UE may receive, from the second UE, a response based at least in part on the sidelink transmission that spans the multiple aggregated slots. Numerous other aspects are described.

Abstract: A first UE transmits, on a first unicast link to a second UE, a first RS from a first TRP of the first UE. The first UE receives, based on the first RS transmitted, a first channel measurement for the first unicast link from the second UE and a first interference measurement for a second unicast link from a third UE. The first UE transmits, on the second unicast link with the third UE, a second RS from a second TRP of the first UE. The first UE receives, based on the second RS transmitted, a second channel measurement for the second unicast link from the third UE and a second interference measurement for the first unicast link from the second UE. The first UE applies SDM for the first unicast link and the second unicast link based on the received channel and interference measurements.
