Method, user equipment and network node for sidelink based energy efficient communication

Abstract

A method for sidelink based energy efficient communication performed by a remote user equipment, UE. According to the method, it is determined whether a random access, RA, procedure failure in a communication with a network node has reached a predetermined threshold. In response to determining that the RA procedure failure has reached the predetermined threshold, the remote UE decides whether to upgrade to a higher coverage enhancement, CE, level in the communication with the network node; or switch to a sidelink communication via a relay UE. Also disclosed is a corresponding remote UE and a corresponding network node.
