Abstract: Techniques for handling sidelink feedback signaling in situations where collisions would otherwise be experienced in a network communication link are shown and described. For example, sidelink feedback signaling handling techniques may provide for collision handling when sidelink HARQ is to be simultaneously transmitted with network communication radio interface uplink channel information (e.g., Uu HARQ, SR, CSI, etc.) on one or more Uu channel (e.g., PUSCH, PUSCH, etc.). In operation of sidelink feedback handling, a transmitter or intermediary UE of a sidelink communication link may decide whether and how to forward the sidelink HARQ to a corresponding base station. Other aspects and features are also claimed and described.

Abstract: In some aspects of the disclosure, a method of wireless communication includes performing a first wireless transmission using a plurality of transmission and reception points (TRPs) of a vehicle. The first wireless transmission is performed based on a first transmit power allocation among the plurality of TRPs. The method further includes, in response to the first wireless transmission, receiving one or more feedback signals indicating a receive status of the first wireless transmission at one or more devices. The method further includes performing a second wireless transmission using the plurality of TRPs based on a second transmit power allocation among the plurality of TRPs. The second transmit power allocation is determined based on at least one received signal strength of the one or more feedback signals.

Abstract: Methods, systems, and devices for wireless communications are described. An example method for wireless communication at a first user equipment (UE) may include receiving at least a first sidelink transmission from a second UE, wherein at least a second sidelink transmission from a third UE is scheduled contemporaneously with at least the first sidelink transmission from the second UE. The method may also include transmitting an indication in a transmission occasion to at least one of the second UE or the third UE based at least in part on a prioritization of information for the transmission occasion, wherein the indication indicates that at least the first sidelink transmission from the second UE is scheduled contemporaneously with at least the second sidelink transmission from at least the third UE.

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: Methods, systems, and devices for wireless communications are described. Some wireless communication system support communications between user equipment (UEs). In the examples, a UE may include two or more transmission reception points (TRPs) and may transmit two or more packets on partially or fully overlapping resources via individual TRPs of the two or more TRPs. The UE may identify a first data packet for transmission using a first spatial layer associated with a first TRP and a second data packet for transmission using a second spatial layer associated with a second TRP. The UE may map a portion of the first data packet to a set of resources of the second spatial layer and transmitting a control message indicating that the portion of the first data packet is mapped to the second spatial layer.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) with multiple transmission reception points (TRPs) (e.g., a multi-TRP UE) may receive sidelink control information including an interference measurement configuration indicating resources allocated for sidelink interference measurements across multiple TRPs. In some cases, the multi-TRP UE may decode the sidelink control information including the interference measurement configuration. The multi-TRP UE may receive one or more signals from a first UE, a second UE, or both. The multi-TRP UE may perform a sidelink interference measurement for each signal based on the interference measurement configuration. The multi-TRP UE may determine whether to process the signals in combination or separately across TRPs based on the sidelink interference measurements.

Abstract: Methods, systems, and devices for wireless communications are described. To improve sidelink reservation schemes. a first user equipment (UE) may indicate its preferences for sidelink resources to a second UE that may select sidelink resources for sidelink messages based on the indicated preferences. For example, the first UE may monitor a first set of sidelink resources for sidelink control information (SCI) to determine which sidelink resources of a second set of sidelink resources are available. Based on the monitoring, the first UE may generate a bitmap that indicates the first UE's preferences for the sidelink resources of the second set and may transmit a coordination message to the second UE that includes the bitmap. The second UE may receive the coordination message and transmit, to the first UE, one or more sidelink messages using one or more sidelink resources of the second set selected based on the indicated preferences.

Abstract: Methods, systems, and devices for wireless communications are described. Techniques are described for a user equipment (UE) to trigger a sidelink channel state information (CSI) procedure without an associated data grant. In some cases, a CSI procedure may be triggered by sending a sequence on a specific resource. In some cases, a CSI procedure may be triggered by a sidelink control information (SCI) message which does not include a sidelink data grant. Techniques are described which avoid CSI reference signal (CSI-RS) resource collision. For example, CSI-RS resources may be selected based on channel sensing, UE identifiers, or a combination thereof. In some cases, UEs may be configured subsets of a CSI-RS resource pool for sending CSI-RS.
