Abstract: In one aspect, a method of wireless communication includes receiving, by a first user equipment (UE), a first transmission from a second UE for a new radio (NR) sidelink channel. The method also includes receiving, by the first UE, a second transmission from a third UE for the sidelink channel. The method further includes transmitting, by the first UE, a feedback transmission based on a medium contention event for the first and second transmissions of the NR sidelink channel and on a range condition. In additional aspects, the feedback transmission is transmitted based on a quality condition, or both a range condition and a quality condition. Other aspects and features are also claimed and described.

Abstract: Certain aspects of the present disclosure provide techniques for multiplexing HARQ feedback in a same slot for downlink and sidelink transmissions. An example method generally includes receiving, from a network entity, a downlink control information (DCI) that schedules resources for at least one physical sidelink shared channel (PSSCH) transmission from the first UE to a second UE, transmitting data to the second UE via the at least one PSSCH transmission using the scheduled resources, receiving, from the second UE, acknowledgment feedback for the at least one PSSCH transmission, selecting at least one codebook entry for providing feedback for at least one downlink transmission from the network entity to the first UE and the acknowledgment feedback for the at least one PSSCH transmission in a same physical uplink control channel (PUCCH) slot, and transmitting the at least one codebook entry to the network entity via at least one PUCCH transmission.

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: Methods, systems, and devices for wireless communications are described. In some systems, a user equipment (UE) may receive scheduling information that schedules an uplink data message over a high priority physical uplink shared channel (PUSCH) that overlaps in time with a physical uplink control channel (PUCCH) resource over which the UE is scheduled to transmit feedback associated with sidelink communication. The UE may receive signaling from a base station indicating whether the feedback associated with the sidelink communication can be multiplexed with the uplink data message on the high priority PUSCH. As such, the UE may multiplex the feedback associated with the sidelink communication on the high priority PUSCH if the signaling from the base station indicates that the feedback associated with the sidelink communication can be multiplexed with the uplink data message on the high priority PUSCH.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a first user equipment (UE) may receive, from a second UE, a resource reservation that indicates a reservation for one or more resources; and transmit an indication that at least one resource of the one or more resources is in conflict with an additional resource reservation, the indication including one or more of an identification of the at least one resource, an identification of the resource reservation, or an identification of the second UE. Numerous other aspects are provided.

Abstract: Methods, systems, and devices for wireless communications are described. A first user equipment (UE) may transmit, within an active duration of a first sidelink discontinuous reception (DRX) pattern of a second UE, sidelink control information (SCI) indicating a resource reservation for a sidelink resource of the sidelink channel within at least a portion of an inactive duration of the first sidelink DRX pattern. The first UE may then communicate, with the second UE via the sidelink channel, a sidelink message within the sidelink resource indicated in the resource reservation.

Abstract: Methods, systems, and devices for wireless communications are described. A communication device, which may be otherwise known as user equipment (UE), may receive a data transmission and determine a slot to transmit a hybrid automatic repeat request (HARQ) feedback based on the data transmission. The communication device may determine one or more HARQ feedback resources or one or more HARQ feedback resource sets in the slot to transmit the HARQ feedback, where the one or more hybrid automatic repeat request feedback resources or the one or more hybrid automatic repeat request feedback resource sets in the slot comprises a set of frequency resources associated with the slot, and transmit the HARQ feedback using the one or more HARQ feedback resources or the one or more HARQ feedback resource sets in the slot.

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.
