Abstract

The present disclosure relates to radio communications. More specifically, the present disclosure relates to possible reductions in overhead signaling. The radio link quality of the first radio link (eg DL) and the second radio link (eg UL) is obtained 130 . Furthermore, the obtained radio link quality of the first radio link is compared 140 with the obtained radio circuit quality of the second radio link. This is done in order to confirm whether the similarity in radio link quality is within a predefined tolerance. Next, controlling 150 signaling for both the first radio link and the second radio link if or when it is determined that the similarity of the radio link quality is within said predefined tolerance.

Description

technical field [0001] Embodiments presented herein relate generally to radio communications. More specifically, embodiments presented herein relate to reducing signaling in radio communication networks. The present disclosure thus proposes methods and arrangements for reducing overhead signaling in radio communication networks (eg radio network devices, radio network control nodes and radio base stations). Background technique [0002] Detailed descriptions of radio communication networks can be found in documents such as technical specifications promulgated by eg the 3rd Generation Partnership Project (3GPP). 3GPP Long Term Evolution (LTE) was developed within the 3rd Generation Partnership Project (3GPP) to improve the Universal Mobile Telecommunications System (UMTS) standard in terms of improved services such as higher data rates, improved efficiency and reduced cost, etc.) to meet the requirements of the fourth generation of radio communication technology standards i...
