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 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 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. Generally, a user equipment (UE) may monitor synchronization signal resources, each synchronization signal resources associated with a beam, and may select a preferred beam based on the monitoring. The UE may transmit an uplink random access message (e.g., message 3 of a four-step random access message, message A of a two-step random access procedure, or a negative acknowledgement (NACK) message requesting retransmission of a random access message) including beam information (e.g., one or more beam indices, channel quality information, or channel state information) to a base station. In response, the base station may transmit a downlink random access message using a different beam (e.g., a new preferred beam). The UE may establish a connection with the base station based on the completed random access procedure.

Abstract: Methods, systems, and devices for wireless communications are described. Generally, a user equipment (UE) may monitor multiple synchronization signal resources, each synchronization signal resource associated with a beam of a set of beams and may determine that multiple candidate beams of the set of beams satisfy a channel quality threshold. The UE may transmit an indication that the multiple candidate beams satisfy the channel quality threshold. For example, the UE may transmit a single random access message on a physical random access channel (PRACH) resource associated with multiple candidate beams, or may transmit multiple random access messages, each one on a different PRACH resource associated with a different candidate beam. The UE may receive an indication of one of the candidate beams from the base station and may establish a connection with the base station using the indicated candidate beam.

Abstract: Methods, computer programs products, and apparatuses for RS availability indication are provided. An example method at a UE may include receiving, from a base station, a PEI comprising a first availability indication for a first set of RS resources in one or more RS occasions. The example method may further include receiving, from the base station, a paging PDCCH comprising a second availability indication for a second set of RS resources in the one or more RS occasions. The example method may further include receiving, from the base station, at least one of the first set of RS resources or the second set of RS resources.

Abstract: Methods, systems, and devices for wireless communications are described. A first device may receive a message indicating a configuration for performing an energy harvesting procedure. The configuration may indicate a pairing of a component carrier and a bandwidth part for the first device to use for performing the energy harvesting procedure. The pairing may be based on one or more measurements associated with the first device. As part of the energy harvesting procedure, the first device may monitor for one or more signals from a second device. The first device may monitor for the one or more signals using a set of resources that correspond to the pairing of the component carrier and the bandwidth part. The first device may receive, from the second device, one or more signals using the set of resources.

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: A method of wireless communication by a base station includes configuring a tracking reference signal (TRS) with respect to a physical downlink shared channel (PDSCH) for an idle/inactive mode user equipment (UE). The method also transmits the tracking reference signal and the PDSCH during a paging cycle, in accordance with the configuration. A method of wireless communication by a UE includes expecting a TRS to be received when a PDSCH is received.
