Abstract

The invention relates to a method in a wireless device for mapping a logical channel to one of a first and a second link. The first link is maintained to a first radio network node and the second link is maintained to a second radio network node. The method comprises obtaining (910) information indicating to which of the first and the second links one or more of at least one logical channel is mapped. The method also comprises selecting (920) a logical channel among the at least one logical channel, and mapping (930) the selected logical channel to one of the first and the second links based on the obtained information. The invention also relates to a corresponding method in the first radio network node.

Description

technical field [0001] The present disclosure relates to a method in a wireless device for mapping a logical channel to one of a first link and a second link, wherein the first link is maintained to a first radio network node and the second link is maintained to a second radio network node of the second link. The present disclosure also relates to a corresponding method in a radio network node, as well as a wireless device and a radio network node. Background technique [0002] 3GPP Long Term Evolution (LTE) is a fourth-generation mobile communication technology standard developed within the Third Generation Partnership Project (3GPP) to improve the Universal Mobile Telecommunications System (UMTS) standard for improved services such as higher data rate), improved efficiency, and reduced overhead to meet future demands. Universal Terrestrial Radio Access Network (UTRAN) is the radio access network of UMTS, and Evolved UTRAN (E-UTRAN) is the radio access network of LTE syst...
