Embodiment Construction

[0036]As part of the embodiments herein, one or more problems associated with using at least some existing solutions and that may be addressed by the embodiments herein are first identified and discussed.

[0037] When a wireless device is in Radio Resource Control (RRC)_CONNECTED mode (RRC connected mode), the Evolved Universal Terrestrial Radio Access Network (E-UTRAN) tracks the location of the wireless device at the cell level, that is, E-UTRAN knows which cell the wireless device is in In order to know which network node, such as eNB, the wireless device is connected to. This means that network nodes can determine the amount of resources required by various services and how to optimize between them.

[0038] When the wireless device is in RRC_IDLE mode (RRC idle mode), the location of the wireless device can be tracked at the Tracking Area (TA) level. Generally, a TA consists of several cells. Each cell broadcasts which TA it is part of, and when a wireless device chang...

Abstract

A method performed by a network node for adapting allocation of radio resources for D2D communication to at least one wireless device is provided. The at least one wireless device is located in a cell served by a network node. The network node obtains a measurement of the interference level on the D2D radio resources allocated to the at least one wireless device. The network node also adapts the allocation of radio resources for D2D communication based on the obtained measurements.

Description

technical field [0001] The present disclosure generally relates to a network node and a method therein for adapting radio resource allocation to at least one wireless device for device-to-device (D2D) communication. The present disclosure also relates generally to a network node and methods therein for employing reconfiguration of radio resource allocation to at least one wireless device for D2D communication. The present disclosure also relates to a computer program and a computer-readable storage medium storing the computer program for performing the aforementioned method. Background technique [0002] A communication device such as a wireless device is also referred to as, for example, user equipment (UE), mobile terminal, wireless terminal and / or mobile station. Terminals are capable of communicating wirelessly in a cellular communication network or wireless communication system (also sometimes referred to as a cellular radio system or cellular network). can be perform...
