Abstract: Methods and apparatuses described herein provide a physical downlink control channel (PDCCH) candidate hopping function that reduces collisions between PDCCH candidates, particularly between PDCCH candidates associated with reduced capability user equipment (UE). For example, the hopping function may be implemented as part of a PDCCH candidate to control channel element (CCE) function or may be applied separately from the PDCCH candidate to CCE function. The hopping function may reduce persistent collisions between PDCCH candidates by correlating the mapping behavior with a value that changes over time. Some techniques and apparatuses described herein provide signaling for configuration and activation/deactivation/modification of the hopping pattern. Thus, collisions between PDCCH candidates are reduced, thereby conserving computing resources and wireless communication resources. Furthermore, the reduction of collisions may improve performance of UEs with reduced PDCCH capabilities, such as reduced-capability UEs. Numerous other aspects are provided.

Abstract: Certain aspects of the present disclosure provide a method for wireless communication by a user equipment (UE). The UE receives an uplink (UL) cancellation indication (ULCI) from a network entity cancelling resources assigned to the UE for UL transmission and indicating the UE to measure cross-link interference (CLI) from one or more other UEs within the cancelled resources. The UE measures the CLI from the one or more other UEs based on the ULCI. The UE sends a CLI measurement report based on the measured CLI to the network entity.

Abstract: Methods, systems, and devices for wireless communication are described. A user equipment (UE) may identify that it is scheduled to transmit an uplink message during one or more symbols of a first transmission time interval (TTI) is scheduled to receive a downlink message during a second TTI subsequent to the first TTI. The UE may advance transmission of the uplink message in accordance with a timing advance (TA) value and a TA offset value, such that the timing advance offset value is zero. The UE may proceed to apply a transient power mitigation scheme to mitigate potential interference to reception of the downlink message during a transient power duration associated with turning off an uplink transmission chain used for transmitting the uplink message. In some examples, the transient power mitigation scheme may be applied based on the TA offset value being zero.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive configurations of a set of tracking reference signal (TRS) resource sets. The UE may receive an availability indication associated with one or more TRS resource sets from the set of TRS resource sets, and the availability indication is associated with one or more groups of TRS resource sets associated with the set of TRS resource sets. Numerous other aspects are described.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive signaling from a base station that includes an indication of a configuration for measuring cross-link interference (CLI) and an indication of a reference subcarrier spacing (SCS). The configuration may be associated with a slot having more than 14 symbols and may indicate a resource allocation that includes a sounding reference signal (SRS) resource, a CLI resource, or both. The UE may use the SRS resource to measure an SRS and may use the CLI resource to measure a received signal strength indicator (RSSI). The UE may measure the SRS and the RSSI according to the reference SCS. The UE may determine a CLI level based on measuring the SRS, the RSSI, or both. The UE may transmit, to the base station, a report including an indication of the determined CLI level.

Abstract: Methods, systems, and devices for wireless communication are described. A user equipment (UE) may receive a first system information message including an indication of a resource configuration for a control resource set (CORESET) from a base station. The CORESET may include a common search space for a downlink control information (DCI) message that schedules a second system information message. The UE may identify a set of parameters from multiple sets of parameters for the CORESET based on the indication received in the first system information message and the UE being a first type of UE. The set of parameters may be different from a second set of parameters for the CORESET associated with a second type of UE different from the first type of UE. The UE may receive, in the CORESET according to the identified set of parameters, the DCI message scheduling the second system information message.

Abstract: In a wireless network, a user equipment (UE) may skip an uplink transmission associated with a dynamic uplink grant. In such cases, when the UE skips an uplink transmission that would have been concurrent with a downlink transmission, the UE may perform one or more mode-dependent control operations. For example, because the uplink transmission would result in a full-duplex operation if the UE were to perform the uplink transmission, the UE may reset a timer associated with switching from a full-duplex mode to a half-duplex mode and/or perform one or more mode-dependent control operations in the full-duplex mode. Alternatively, because the UE refrains from performing the uplink transmission that would have resulted in a full-duplex operation, the UE may maintain the timer associated with switching from the full-duplex mode to the half-duplex mode and/or perform the one or more mode-dependent control operations in the half-duplex mode.

Abstract: Aspects relate to wireless communications utilizing cross carrier scheduling Methods and apparatus include generating at least one slot in a control channel from a scheduling cell, the at least one slot including a plurality of control channel segments such as PDCCH segments, which are arranged at respective times within the at least one slot. Each of the control channel segments includes control information such as DCIs corresponding to respective slots for a scheduled cell. Distributing the control channel information in segments or spans over time affords improved decoding timing in a UE in the scheduled cell.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may decode a downlink communication on a physical downlink shared channel (PDSCH). The downlink communication may have punctured resources. The UE may transmit, in association with the downlink communication, a first uplink communication on a physical uplink shared channel (PUSCH), and measure self-interference in the punctured resources of the downlink communication on the PDSCH that are within a threshold distance of resources of the first uplink communication on the PUSCH. Numerous other aspects are provided.
