Handover Request Indicating Split of a Radio Bearer between Cells

摘要

A method in a first network node for splitting of a DL part and an UL part of a radio bearer between a first cell and a second cell in a wireless communications network. The radio bearer is associated to DL and UL transmissions between the first network node and a user equipment in the first cell. The first network node transmits (1904) a handover request. The handover request indicates splitting of the DL part and the UL part of the radio bearer between the first cell and the second cell. The first network node receives (1905) a handover request acknowledge of the handover request. The handover request acknowledge indicates admission of the splitting.
