USER EQUIPMENT AND BASE STATION PARTICIPATING IN A SYSTEM INFORMATION ACQUISITION PROCEDURE

Abstract

The present disclosure relates to a user equipment comprising a receiver receiving a minimumsystem-information message from a first radio base station. System information for the first radio cell that can be acquired by the UE is carried within the minimum-SI message and one or more additional-SI messages. The minimum-SI message includes system information for accessing the first radio cell and at least one system information index, each of which is associated with one of the additional-SI messages. The SI message index comprises a value tag and an area pointer, the latter pointing to one area already defined. Processing circuitry determines whether the UE had already acquired before the additional-SI message associated with the same value tag and the same area. If the determination is positive, the processing circuitry determines that system information included in said additional-SI message acquired before is applicable to the first radio cell.
