Embodiment Construction

[0040] A problem that was part of the development of the embodiments herein will be addressed and discussed first.

[0041] In a D2D network, there may be signaling that may be the same for D2D devices of a D2D pair, such as control signaling from a network node. In fact, in the D2D network, a different control signaling type than the one mentioned in the background section is introduced, the control signaling used for the control signaling of the D2D pair Media Access Control Control Element (MAC CE) and / or RRC signaling. Examples of such control signal types are the Time Division Duplex (TDD) configuration of the pair or the Beacon / Reference Signal (RS) configuration of the pair. If this same signaling is sent to each D2D device of a D2D pair in a conventional or dedicated manner, radio resources such as downlink control information (DCI) and physical downlink shared channel (PDSCH) will be wasted, thereby affecting The total capacity and latency of the system. Relying on...

Abstract

Method in a network node for allocating UL radio resources to a pair of D2D devices comprising a first wireless device and a second wireless device, the network node and the D2D pair being comprised in a wireless communications network, the method comprising: assigning a common DL control signalling message, for the pair of D2D devices; and allocating UL radio resources to the first wireless device and the second wireless device, so that the UL radio resources allocated to the first wireless device are separated from the UL radio resources allocated to the second wireless device, by applying one or more of a time offset, a frequency offset and a code-division multiplexing offset between the UL radio resources allocated to the first wireless device and the UL radio resources allocated to the second wireless device, wherein the allocating UL radio resources is based on the common DL control signalling message.

Description

technical field [0001] Embodiments herein relate to network nodes and methods therein. In particular, embodiments herein relate to allocating uplink (UL) radio resources for device-to-device (D2D) device pairs. Background technique [0002] A device such as a wireless device is also referred to as eg user equipment (UE), mobile terminal, wireless terminal and / or mobile station. A device is capable of communicating wirelessly in a wireless communication system or a wireless communication system that is also sometimes referred to as a cellular wireless system or cellular network. Communications may be performed between, for example, two devices, a device and a landline and / or a device and a server via a radio access network (RAN) and possibly one or more networks included in the wireless communication system. [0003] The device may also be called a mobile telephone, a cellular telephone, or a wireless enabled laptop computer, etc., just to name a few other examples. A devi...
