Abstract: Example embodiments of the present disclosure relate to apparatuses, methods, and computer readable storage medium for beamlock on a plurality of antenna arrays. In a method, a first apparatus receives a beamlock message from a second apparatus. The beamlock message indicates that one or more transmitting beams are to be locked on a first list of antenna arrays and/or one or more receiving beams are to be locked on a second list of antenna arrays. Based on the beamlock message, the first apparatus performs beamlock of the one or more transmitting beams and/or the one or more receiving beams.

Abstract: Embodiments of the present disclosure relate to apparatuses, methods, devices and computer readable storage medium to trigger loop backing of protocol data units (PDUs) in conformance testing. The method comprising: at a first apparatus, the first apparatus receives, from a second apparatus, a configuration of a test loop mode for the first apparatus at least indicating one or more timers for delaying a plurality of PDUs buffered in the first apparatus and the number of PDUs to be looped back in a test loop from the first apparatus to the second apparatus at an expire of each of the one or more timers; and the first apparatus participates in a conformance test at least based on the configuration.

Abstract: Various example embodiments relate to devices, methods, apparatuses and computer readable mediums for virtual cable calibration in over the air conformance testing. In an example embodiment, a terminal device may receive training signals from at least four probes, estimate a channel based on the received training signals, and transmit a representation of the estimated channel to a test equipment coupled to the at least four probes. The terminal device and the at least four probes are positioned in a testing chamber. The estimated channel includes an over the air, OTA, channel portion between the at least four probes and the terminal device. The representation of the estimated channel is transmitted to the test equipment for compensation of the OTA channel portion.

Abstract: Embodiments of the present disclosure relate to a test framework to evaluate the CSI prediction accuracy for AI/ML based CSI prediction use case without the need for the DUT to send the ground truth to the test equipment separately. Further, embodiments of the present disclosure propose a procedure to obtain the parameter values predicted by the DUT and the corresponding ground truth at the TE side independently during the conformance testing.

Abstract: A method may include determining that a user equipment is in a radio resource control, RRC, non-connected state. The method may also include broadcasting a system information block, SIB, to a plurality of user equipment including the user equipment. The system information block SIB includes a non-access stratum, NAS, container for conveying a NAS message to the user equipment. In the method, the RRC non-connected state includes an RRC inactive state or an RRC idle state.
