Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may be receive a grant configuration including multiple set of parameters, and the UE may select a set of parameters from the configured grant based on a channel condition. In some examples, the UE may be configured to signal to a network (e.g., a base station) the selected set of parameters and their corresponding parameter values. For example, the UE may be configured to signal the selected set of parameters over semi-static signaling (e.g., radio resource control (RRC) messaging) or dynamic signaling (e.g., medium access control-control element (MAC-CE) messaging, uplink control information (UCI) messaging, or the like). By configuring the UE with multiple set of parameters, the UE may adapt to changing channel conditions, which may provide higher reliability and lower latency for wireless communications, as well as reduce power consumption for the UE.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE may be configured to communicate with a base station in a discontinuous reception (DRX) mode according to a DRX cycle. The UE may receive signaling that indicates a configuration of a ramp window associated with the DRX cycle. The ramp window may include a set of slots that is adjacent to a sleep window of the DRX cycle and, in some examples, is adjacent to an on-window of the DRX cycle. The set of slots may include a first subset of wakeup slots and a second subset of sleep slots. During the ramp window, the UE may monitor for a transport block from the base station during the first subset of wakeup slots. If the UE receives the transport block during a wakeup slot, the UE may transition to the on-window of the DRX cycle.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, from a network node, an indication of one or more data radio bearers between the UE and the network node that are configured for application data unit (ADU) traffic. The UE may communicate, with an application server, one or more ADU traffic flows through the network node using the one or more data radio bearers. Numerous other aspects are provided.

Abstract: This disclosure provides systems, methods, and apparatus, including computer programs encoded on computer-readable media, for a service-based cell reselection by a user equipment (UE) in a wireless communication system. The UE may have a service relationship with a particular service. A wireless communication system may provide different types of services via different radio frequencies. The UE may determine which cells to measure for cell reselection to include those that correspond to a service of interest to the UE. In addition to power savings, the UE may experience faster cell reselection for a service. The techniques of this disclosure also may enable a priority-based cell reselection so that the UE can camp on a cell that supports a higher priority service compared to other services supported by the UE.

Abstract: Methods, systems, and devices for wireless communications are described. A wireless communications entity, such as a user equipment (UE), a base station, a network core, or an application server, may identify a round-trip time (RTT) latency requirement that may pertain to a round-trip latency in wireless communications between the UE and the base station. The wireless communications entity may identify a one one-way directional delay budget that satisfies the RTT latency requirement for an application of an application server. The application server may be in communication with the UE via the base station. The wireless communications entity may modify a value of the one-way directional delay budget and transmit a message that is associated with the modified value of the one one-way directional delay budget.

Abstract: Certain aspects of the present disclosure provide techniques for wireless communication and more particularly, to techniques for bandwidth part adaptation for extended reality (XR) power saving. A method that may be performed by a UE generally includes receiving a first configuration of a first bandwidth part (BWP) and a second configuration of a second BWP, wherein the first BWP is configured for a lower traffic rate and the second BWP is configured for a higher traffic rate; obtaining an indication to switch from the first BWP to the second BWP; and switching from the first BWP to the second BWP in response to obtaining the indication.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may monitor a reception occasion for a short message that includes a system information change notification or a public warning system notification. The UE may initiate a mitigation action related to a radio link with a network based at least in part on non-reception by the UE of the short message in the reception occasion, failure of the short message to pass an integrity check, and/or the like. Numerous other aspects are provided.

Abstract: The present disclosure relates to methods and devices for graphics or data processing including an apparatus, e.g., a network, a server, or a client device. In some aspects, the apparatus may transmit a request for an updated FEC rate, the updated FEC rate being based on a previous FEC rate. The apparatus may also receive, based on the request for the updated FEC rate, information associated with the updated FEC rate. Additionally, the apparatus may determine the updated FEC rate based on the received information, the received information being associated with a difference between the previous FEC rate and the updated FEC rate.
