Abstract

A method in a network node for multiplexing physical channels 400 between network nodes and devices included in a hybrid wireless network, wherein the hybrid wireless network also includes a cellular network with one or more cellular channels and a A D2D network of one or more device-to-device D2D channels, the method comprising: time-division multiplexing a physical channel 400 between a first group of cellular channels and a first group of D2D channels, and between a second group of cellular channels The physical channel 400 is frequency division multiplexed between the group and the first group of D2D channels.

Description

technical field [0001] Embodiments herein relate to network nodes and methods therein. In particular, embodiments herein relate to multiplexing of physical channels. Background technique [0002] Apparatus such as User Equipment (UE) are also referred to as eg mobile terminals, wireless terminals and / or mobile stations. The devices are capable of wireless communication in a wireless communication system, sometimes also referred to as a cellular radio system or cellular network. Communication may be between two devices, between a device and a regular phone and / or between a device and a server, for example via a radio access network (RAN) and possibly one or more core networks comprised within a wireless communication system implement. [0003] A device may also refer to a mobile telephone, a cellular telephone, or a laptop computer with wireless capabilities, just to name a few other examples. A device in this context may be, for example, a portable, small, hand-held, com...
