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. A user equipment (UE) may use an increased transmit power for one or more instances of an autonomous uplink transmission. For example, a UE may be configured with a repetition window including multiple transmission time intervals (TTIs) and may identify a subset of TTIs within the window that may be unavailable for autonomous uplink transmissions. The UE may adjust transmit power or transmit a scheduling request based on the presence of unavailable TTIs. In some examples, the UE may increase the transmit power by an amount that is based on a number of unavailable TTIs, or a fixed amount, or a combination thereof. In some examples, a UE with limited transmit power (e.g., under a maximum transmit power) may dynamically transmit a report to a base station that includes a request to modify a communications scheme used by the UE.

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: Dynamically adaptive numerologies for ultra-reliable low-latency communications (URLLC) are discussed in which a base station may determine performance characteristics for each user equipment (UE) that it serves, in addition to detecting any fluctuations in system loading at the base station. Based on this information, the base may be select for each of the served UEs an adapted numerology that provides an optimized set of configurations that assist the communications between the base station and each UE to meet the strict parameters for URLLC. Once selected, the base station signals the selected adapted numerology to the UEs either through broadcast or UE-specific communications.

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 related to wireless communication systems and transmission and/or reception of synchronization signal block (SSB) transmissions are provided. In some scenarios, communications may occur in one or more full-duplex slots. For example, a wireless communication device receives a synchronization signal block (SSB) transmission schedule. The SSB transmission schedule at least partially overlapping with an uplink (UL) frequency portion of a full-duplex slot. The wireless communication device receives one or more SSBs, where the one or more SSBs are received in at least a slot different than the full-duplex slot or in a DL frequency portion of the full-duplex slot. Other features are also claimed and described.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may communicate with a base station via a first instance of a periodic data burst, where the periodic data burst may include one or more uplink or downlink transmissions scheduled on a first bandwidth part (BWP). The UE may start a bandwidth switching timer at the beginning of the first instance of the periodic data burst, and determine whether the bandwidth switching timer has expired upon expiration of an inactivity timer that was triggered by receipt of one or more downlink control channel messages. The UE may operate, based on the determination, on one of the first BWP or a second BWP during at least a portion of a time period that extends from the expiration of the inactivity timer and a beginning of a second instance of the periodic data burst.

Abstract: Methods, systems, and devices for wireless communications are described. A network entity may account for jitter in communications with a user equipment (UE) by adjusting connected mode discontinuous reception (CDRX) configuration parameters for the UE based on estimated downlink traffic arrival times. For a downlink traffic burst, the network entity may estimate a traffic arrival offset based on determining a traffic periodicity, an estimated arrival time associated with one or more packets of a traffic burst, and at least one jitter parameter. The jitter parameter may represent an uncertainty in the arrival time of the traffic burst. The network entity may select a CDRX offset value based on the estimated traffic arrival offset. The network entity may transmit (e.g., to a UE, such as an extended reality (XR) device) a message indicating the CDRX offset value, for example, as part of a CDRX configuration.

Abstract: A method of wireless communication includes receiving, by a user equipment (UE), a plurality of uplink configured grant (UL-CG) configurations and receiving, by the UE, an UL-CG. The method further includes selecting, based on a resource configuration associated with a slot, an UL-CG configuration from among the plurality of UL-CG configurations for an occasion of the UL-CG that is to occur during the slot. The method further includes performing an uplink transmission during the occasion of the UL-CG based on the selected UL-CG configuration.

Abstract: Certain aspects of the present disclosure provide techniques for compact downlink control information (DCI) signaling design for ultra-reliable low-latency communications (URLLC). A method for wireless communications performed by a base station (BS) is provided. The method generally includes generating DCI, the DCI scheduling at least one transmission, according to a first DCI format. The first DCI format is compressed relative to a second DCI format and includes a carrier indicator field (CIF) and/or a rate-matching indicator field. The BS transmits the DCI to a user equipment (UE). The UE communicates with the BS based on the received DCI.
