METHODS, RADIO NETWORK NODES AND A USER EQUIPMENT

摘要

A method (400) in a radio network node (220) of a wireless communication system (200) for selecting a MSG3 size for a User Equipment (UE) (230) that is performing handover from a serving network node (210) to a neighbour network node (220) is disclosed. The method (400) comprises receiving (S402) 5 measurement information related to the UE (230) from the serving network node (210). The method (400) comprises selecting (S404) the MSG3 size based on the measurement information. The method (400) further comprises transmitting (S406) the MSG3 size to the UE (230), based on which UE related information is transmitted to the neighbour network node (220).
