Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) or multiple UEs may transmit a grant-free uplink transmission to a base station. The base station may monitor resources for the grant-free uplink transmission (e.g., from one or more UEs) and the base station may generate a group feedback message corresponding to whether the base station successfully received the uplink transmission(s). The group feedback message may contain feedback for multiple uplink transmissions from one or multiple UEs. The group feedback message may be transmitted to a UE over a downlink shared channel or a downlink control channel and the UE may receive the group feedback message and may determine whether to retransmit the uplink transmission based on the group feedback message.

Abstract: Methods related to wireless communication systems and transmission and/or reception of synchronization signal block (SSB) transmissions (e.g., in full-duplex slots) are provided. For example, a wireless communication device receives a synchronization signal block (SSB) transmission schedule. The SSB transmission schedule is at least partially overlapping with an uplink (UL) frequency portion of a full-duplex slot. The wireless communication device receives a first portion of a SSB in a downlink (DL) frequency portion of the full-duplex slot; and receiving a second portion of the SSB in the UL frequency portion of the full-duplex slot based on the SSB being scheduled in the full-duplex slot and at least partially overlapping with the UL frequency portion of the full-duplex slot. Other features are also claimed and described.

Abstract: Some wireless communications systems may support logical channel prioritization (LCP) adaptation. A user equipment (UE) may receive signaling scheduling multiple data flows associated with a set of channels in particular logical channels, where each data flow of the multiple data flows is associated with a set of one or more parameters. The UE may calculate a deadline metric (DM) associated with a transmission time of each data flow based on the sets of one or more channel prioritization parameters and may adapt the set of one or more parameters associated one or more data flows of the multiple data flows based at least in part on the DM. The UE may transmit a first data flow of the multiple data flows based at least in part on a prioritization of the first data flow over a second data flow, the prioritization based at least in part on the adapting.

Abstract: Methods, systems, and devices for wireless communication are described. In one example, a base station may dynamically configure a user equipment (UE) to monitor or avoid monitoring for a preemption indication. Accordingly, the UE may have a lower chance of monitoring for a preemption indication when it is unlikely that an uplink or downlink transmission will be preempted. In another example, a base station may transmit a control message indicating whether future indications received from the base station are to be interpreted as preemption indications or permission indications. Accordingly, the base station may choose to use either preemption indications or permission indications (e.g., based on the probability of collisions between mobile broadband (MBB) and low latency transmissions) to facilitate MBB and low latency communication multiplexing with limited signaling.

Abstract: Methods, systems, and devices for wireless communications are described that provide improved repetition techniques for autonomous uplink transmissions. Configuration information may be provided from a base station to a user equipment (UE) for autonomous uplink transmissions, that may indicate initial resources for an initial uplink transmission slot and retransmission resources for a number of retransmissions. Time resources within the retransmission resources may be configured to provide enhanced reliability, such as by being configured in non-contiguous slots to avoid one or more other transmission channels. Time resources within slots may also be configured to prevent persistent collisions with autonomous uplink transmissions or retransmissions of two or more different UEs.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive multiple transport blocks (TBs) representing an application data unit (ADU) from a base station. The base station may transmit an indication that the UE is to provide ADU level feedback. The UE may determine the ADU level feedback based on whether the ADU is successfully received and decoded or not. The UE may indicate the ADU level feedback for the TBs to the base station. The base station and the UE may communicate according to the ADU level feedback.

Abstract: Wireless communications systems and methods related to applying an uplink (UL) cancellation indication are provided. A UE may receive downlink control information (DCI) from a base station (BS). The DCI may include an uplink (UL) cancellation indication that references a plurality of resources in one or more full-UL slots and one or more full-duplex slots. The UE may refrain, based on the UL cancellation indication, from transmitting a communication in at least one of a first resource of the plurality of resources in the one or more full-UL slots or a second resource of the plurality of resources in the one or more full-duplex slots. Other aspects and features are also described.

Abstract: Methods, systems, and devices for wireless communications are described. In some wireless communications systems, a transmitting device may be configured to transmit a transport block in a set of transmission time intervals (TTIs) of a repetition window to improve the chances that the transport block is received by a receiving device. In some cases, however, the transport block may not be available to be transmitted in the repetition window until after a first TTI of the repetition window. In such cases, a transmitting device may use the techniques described herein to identify appropriate configurations for transmitting the transport block in the repetition window. For example, the transmitting device may identify an adjusted redundancy version sequence to use for transmitting the transport block in the repetition window or the transmitting device may adjust a repetition window based on a TTI in which the transport block is available to be transmitted.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive, from a base station in wireless communication with the UE, an allocation of time and frequency resources for an uplink transmission of a first communication type associated with a threshold reliability or latency metric. The UE may monitor a control channel for an uplink preemption indication from the base station, the uplink preemption indication indicating whether the UE should transmit the uplink transmission using the first communication type associated with the threshold reliability or latency metric. The UE may then process the uplink transmission based on monitoring the control channel for the uplink preemption indication.

Abstract: This disclosure provides systems, methods, and devices for wireless communication that support enhanced beam management using extended reality (XR) perception data. In a first aspect, a method of wireless communication includes establishing a communication connection between a user equipment (UE) and a serving base station using a current serving beam selected by the UE from a plurality of available beams paired with a serving base station beam. The method further includes obtaining, perception information from one or more extended reality sensors associated with the UE and determining, in response to detection of UE movement, a transpositional representation of the movement using the perception information. The UE may then select a new serving beam in accordance with the transpositional representation. Other aspects and features are also claimed and described.
