Systems, methods, apparatuses, and computer program products for mobility failure evidence-related operations. A UE may measure, record, and report a channel access waiting (CAW) time period that elapsed from having a handover-related message in a transmission buffer until a channel for transmission of the handover-related message was obtained or until an acknowledgement or negative acknowledgement from a receiver of the handover-related message was received. The CAW time period information may be provided to a network node, and the network node may control mobility robustness optimization based on the received information.

The subject matter described herein includes methods, systems, and computer readable media for proactive network testing. One method for proactive network testing includes receiving, by a test controller and via a network tap, at least one metric associated with live network traffic; determining, by the test controller and using the at least one metric and a threshold value associated with the at least one metric, that a network test is to be performed; configuring, by the test controller, a first test agent to execute the network test; and executing, by the first test agent, the network test.

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment may receive an indication identifying a physical downlink control channel (PDCCH) monitoring location associated with receiving a next downlink control information (DCI) communication. The user equipment may monitor in the PDCCH monitoring location based at least in part on the indication. The indication may be valid at least until the PDCCH monitoring location, irrespective of an amount of time between receiving the indication and monitoring in the PDCCH monitoring location. Numerous other aspects are provided.

Certain aspects of the present disclosure provide techniques for cross-carrier retransmission. A method that may be performed by a user equipment (UE) includes monitoring for an initial transmission of data from a network on a first entity, generating a negative acknowledgement message indicating that decoding of the initial transmission of the data was unsuccessful, transmitting the negative acknowledgement message, and monitoring for a retransmission of the data on a second entity after the transmission of the negative acknowledgement message, the second entity being different than the first entity.

The present solution ensures that the UEs are able to make use of all the available reference signals that can be used in a cell for performing UE measurements, estimations or demodulations. That is achieved by indicating on a downlink common or shared channel, the MIMO mode settings associated with a specific network node. The indicated MIMO mode settings explicitly or implicitly indicate available common reference signals and/or dedicated reference signals to be used for said UE measurements, estimations or demodulations, which implies that measurements, estimations or demodulations can be performed based on said received indication.

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, from a base station, a beam failure detection reference signal (BFD-RS). The UE may determine, autonomously at the UE based at least in part on the BFD-RS, a beam failure instance (BFI) count for different types of BFI including BFI noise and BFI interference. The UE may detect a beam failure based at least in part on the BFI count satisfying a threshold. Numerous other aspects are described.
