US 11,153,789 B2 · Method, network node and user equipment of a wireless network for handling a user equipment

Abstract

A method is disclosed performed by a first network node (110) of a wireless communication system (100) for handling of a UE (150) connected to the first network node (110), wherein a second network node (120) of the communication system (100) has a first transmission resource (130) for wireless transmission using a first access technology and a second transmission resource (140) for wireless transmission using a second access technology. The first and the second transmission resources (130, 140) are collocated. The method comprises receiving, from the UE (150), an indication of fulfilled transmission condition for transmission from the second transmission resource (140) to the UE (150), the indication being based on a transmission quality measurement performed by the UE (150) on a wireless signal transmitted by the first transmission resource (130), and determining whether the UE (150) is to be served by the second access technology transmission resource (140) of the second network node (120). The method further comprises, sending, based on the result of the determining, an instruction to the UE (150) to prepare for receiving data in a carrier bandwidth of the second access technology, and sending an instruction to the second network node (120) to prepare for transmitting data from the second access technology transmission resource (140) at the carrier bandwidth of the second access technology.
