METHOD, USER EQUIPMENT AND ACCESS NETWORK NODE

WIPO Patent Application WO/2023/189902

A1

A system (1) is disclosed in which an access network node (base station) (5) performs channel adaptation of a radio interface between a user equipment (UE) (3) and the radio access network node. The access network node information for determining, by the UE, whether a channel quality of the radio interface has been changed. The access network node receives, from the UE, at a channel quality reporting occasion, a periodic channel quality report including information indicating a current channel quality value, in a case where the UE determined that a current channel quality value of the radio interface has been changed from a previous channel quality value transmitted to the access network node.
