Abstract: An improved manner of transmitting and receiving messages in sidelink communication is presented in which a wireless device receives sidelink control information (SCI) that indicates a zone ID associated with a sidelink message. The wireless device determines a location of the wireless device and determines whether to send feedback for the sidelink message based, at least in part, on the zone ID associated with the sidelink message and the location of the wireless device. The feedback may include hybrid automatic repeat request (HARQ) feedback, and the sidelink message may include a groupcast message. The wireless device may further receive an indication of an intended range in the SCI and may determine whether to send the feedback based on a combination of the zone ID and the intended range for the sidelink message.

Abstract: The apparatus may be a base station. The apparatus processes a first group of synchronization signals. The apparatus processes a second group of synchronization signals. The apparatus performs a first transmission by transmitting the processed first group of the synchronization signals in a first synchronization subframe. The apparatus performs a second transmission by transmitting the processed second group of the synchronization signals in a second synchronization subframe.

Abstract: In an aspect, a network device (e.g., BS, core network component, etc.) determines a self-interference measurement (SIM) configuration associated with null-forming at a wireless device (e.g., UE or BS), the null-forming associated with steering at least one receive beam of the wireless device and/or at least one transmit beam of the wireless device away from one or more external sources of self-interference. The network device transmits the SIM configuration to the wireless device. The wireless device performs at least one null-forming procedure in accordance with the SIM configuration.

Abstract: An apparatus for wireless communication includes a receiver and a transmitter. The transmitter is configured to transmit of a transport block (TB) via a sidelink that is associated with a wireless communication protocol. The wireless communication protocol specifies that a first transport block size (TBS) associated with the TB is based on a first set of parameters. The transmitter is further configured to transmit sidelink control information (SCI) associated with the TB via the sidelink, and the SCI includes a TBS adjustment value associated with the first TBS.

Abstract: Methods, systems, and devices for wireless communications are described. When operating in a high-pathloss mode, wireless devices in a network may transmit or receive downlink control information (DCI) that schedules a transmission time interval (TTI) for a physical shared channel (such as a physical uplink shared channel (PUSCH) or a physical downlink shared channel (PDSCH)). A wireless device may determine one or more intervals that correspond to a periodic signal that collides with portions of the TTI. Based on the identified intervals, the wireless device may communicate over the physical shared channel during the TTI. In such cases, the TTI may overlap in time with the one or more intervals to allow communication of the periodic signal during the portions of the TTI. For instance, a periodic signal may be transmitted or received during each of the one or more intervals.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may transmit, to a base station, an indication of an antenna subarray based at least in part on a determination of the antenna subarray from an antenna array of the UE, and receive, from the base station, an indication of reference signals to be used for beam training based at least in part on the indication of the antenna subarray. Numerous other aspects are provided.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a network node may receive an indication of a first set of parameters that corresponds to a direct communication link between an industrial internet-of-things (IIoT) device and a first controller; receive an indication of a second set of parameters that corresponds to an indirect communication link between the IIoT device and the first controller through a second controller; and schedule a communication on at least one of the direct communication link or the indirect communication link based at least in part on the first set of parameters and the second set of parameters. Numerous other aspects are provided.

Abstract: This disclosure provides systems, methods, and apparatus, including computer programs encoded on computer-readable media, for implementing signaling for indicating a scheduled full duplex (FD) uplink (UL) and downlink (DL) traffic scheduling combination for differentiation of FD traffic. In some aspects, a BS may transmit a downlink control information (DCI) message that includes an indication of the scheduled FD UL and DL traffic scheduling combination. The FD UL and DL traffic scheduling combination may identify scheduled UL and DL transmissions for FD mode operation. The UE may receive the DCI message and identify the scheduled FD UL and DL traffic scheduling combination. In some aspects, the BS may provide a DCI message to the UE that indicates whether a DL transmission is being scheduled that at least partially overlaps with a scheduled UL transmission. The UE may initiate a power save mode based on the received DCI message.

Abstract: Certain aspects of the present disclosure provide techniques for managing beam failure recovery operations. A method that may be performed by a user equipment (UE) generally includes performing beam failure detection (BFD) of a beam pair link (BPL) associated with a secondary cell (Scell) of a base station (BS), sending a beam failure recovery request (BFRQ) message in another cell of the BS, the BFRQ message including an indication of a candidate recovery beam for the Scell, and starting a timer based on sending the BFRQ.

Abstract: Methods, systems, and devices for wireless communications are described. In some examples, a base station may identify one or more communication paths to a user equipment (UE), and may determine an end-to-end signal quality for each communication path (e.g., a signal-to-noise ratio (SNR)), one or more hop SNR values for each hop of each communication path, a ratio of the hop SNR values and the end-to-end SNR of each communication path, or a combination thereof. Based on the determined SNR values, ratios, or both, the base station may select a first communication path for a first type of communications (e.g., uplink, downlink, signal type, or the like) and a second communication path for a second type of communications (e.g., uplink, downlink, signal type, or the like), and may communicate with the UE using the selected communication paths.
