Abstract

The present disclosure mainly relates to improvements for the buffer status reporting and the logical channel prioritization procedures performed in the UE, in scenarios where the UE is in dual connectivity and the PDCP layer of the UE is shared in the uplink for MeNB and SeNB. According to the present disclosure, a ratio is introduced according to which the buffer values for the PDCP are split in the UE between the SeNB and the MeNB according to said ratio.
