Abstract: Methods, systems, and devices for wireless communications are described. The method may include a user equipment (UE) receiving one or more first messages that indicate one or more configurations for communications between the UE and a network entity during a plurality of periodic communication occasions. The method may also include receiving a control message that activates at least one of the one or more configurations and schedules multiple instances of the communications. Upon receiving the control message, the UE may communicate the multiple instances in accordance with the at least one of the one or more configurations, each of the multiple instances including a different set of transport blocks.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) flexibly prioritize between communication resources and measurement gaps to resolve collisions between communication resources and measurement gaps. For collisions between a dynamically scheduled communication resources and a measurement gap, a UE may communicate using the scheduled communication resource based on at least one of a time between reception of the downlink control message and a start of the measurement gap satisfying a first threshold duration or a second period of time between reception of the downlink control message and a start of the communication resource satisfying a second threshold duration. For collisions between periodic communication resources and periodic measurement gaps, a UE may either perform a measurement during the measurement gap or communicate using the communication resource based on a priority scheme associated with the measurement gap and the periodically scheduled communication resource.

Abstract: Methods, systems, and devices for wireless communications are described. In some systems, a user equipment (UE) may communicate with a base station using an operating bandwidth part (BWP) that includes a first set of frequency resources. The UE may receive a group-common downlink control information (GC-DCI) message from the base station that includes a resource format indicator (RFI) for the UE (e.g., among multiple RFIs for a set of UEs in the GC-DCI) indicating a second set of frequency resources. The UE may modify the operating BWP based on the second set of frequency resources and communicate with the base station using the modified operating BWP. In some examples, the UE may switch the operating BWP to the second set of frequency resources or may reduce the operating BWP to a set of overlapping frequency resources between the first and second sets of frequency resources.

Abstract: Apparatus, methods, and computer-readable media for facilitating sidelink resource pool activation and deactivation for sidelink communication are disclosed herein. An example method for wireless communication at a first sidelink device includes identifying a configuration of a bandwidth part (BWP) for sidelink communication. In some examples, the BWP may comprise at least a first resource pool including a first subset of frequency resources and a second resource pool including a second subset of frequency resources. The example method also includes receiving an activation indication activating the second subset of frequency resources of the second resource pool. Additionally, the example method includes activating the second subset of frequency resources of the second resource pool based on the activation indication.

Abstract: Disclosed are techniques for wireless communication. In an aspect, a UE determines a frequency hopping pattern for transmission of a physical random access channel (PRACH) preamble based on an associated PRACH coverage enhancement (CE) level, and transmits the PRACH preamble in accordance with the frequency hopping pattern and the associated PRACH CE level. A base station receives the PRACH preamble, and transmits a response (e.g., Msg2 or MsgA) to the PRACH preamble.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may support various extended reality (XR) applications. In some examples of XR applications, features from the real and virtual environments may be overlaid and displayed to a user for consumption via the UE. To avoid visual conflicts, such as misaligning objects from the real and virtual environments, and other visual conflicts, the UE may generate and send pose information to a network (e.g., a server hosting the XR application). The UE may be configured to manage transmission of pose information to the network, which may result in reduced power consumption. For example, the UE may determine a downlink burst occasion for the XR application, generate pose information associated with the UE and the XR application, and transmit the pose information only during the downlink burst occasion.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may identify an indication of a wakeup signal (WUS) configuration for the first UE, the WUS configuration indicating a WUS monitoring occasion for sidelink wakeup signaling between the first UE and a second UE. The UE may determine a first set of resources for transmission of a WUS by the first UE within the WUS monitoring occasion based on the WUS configuration, the first set of resources disjoint in time with a second set of resources for the second UE within the WUS monitoring occasion. The UE may transmit the WUS to the second UE using the first set of resources within the WUS monitoring occasion based on an identification of traffic for the second UE at the first UE.

Abstract: Methods, systems, and devices for wireless communications are described. Generally, a base station may dynamically and reliably indicate that pending transmissions are part of a full duplex operation via downlink control information (DCI) designs described herein. For example, a base station may transmit, to a user equipment (UE) a DCI including no more than one downlink grant and no more than one uplink grant for a full duplex operation. In some examples, the base station may transmit a first-stage DCI including partial information, and second-stage DCIs including full uplink and downlink grants for a full duplex operation. In some examples, the base station may configure periodic or semi-periodic uplink and downlink resources that may overlap in time, and may dynamically indicate, to the UE, whether the overlapping uplink and downlink resources are scheduled for a full duplex operation.

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.
