Abstract: Example embodiments of the present disclosure are related to artificial intelligence/machine learning (AI/ML) model test. A first apparatus transmits test configuration information to a second apparatus, the test configuration information indicating a test mode of an AI/ML model with respect to at least one transmission and reception unit (TRP), the at least one TRP being arranged within an environment based on a test plan for at least one test channel indicator. The first apparatus receives, from the second apparatus, at least one predicted channel indicator for the at least one TRP, the at least one predicted channel indicator being derived by the second apparatus using the AI/ML model. The first apparatus determines a test result for the AI/ML model based on a comparison between the at least one predicted channel indicator and the at least one test channel indicator, the test result indicating whether the AI/ML model is validated.

Abstract: A method is provided that includes monitoring a radio link quality at a user equipment connected to both a first transmission-reception point (TRP) and a second TRP of a network. The user equipment having a first downlink (DL) connection and a second DL connection with respectively the first TRP and the second TRP, but an uplink (UL) connection with with the second TRP but not the first TRP, and the radio link quality monitored is of the second DL connection with the second TRP. The method includes identifying a condition for switching the UL connection, based on at least the radio link quality of the second DL connection, and switching the UL connection from the second TRP to the first TRP, based on the determination.
