Embodiment Construction

[0108] figure 1 A method of managing wireless resources for D2D communication in a wireless network according to a basic embodiment of the present invention is shown.

[0109] In a first step 101 of the method 100, angle information of at least one C-UE and / or at least one D-UE relative to a base station in a cell is determined. In order to determine the angular information eg AoA or TDoA measurements may be performed. The angle information can be performed by the base station of the cell. However, a management entity may be provided to obtain angle information for one or more cells.

[0110] In a second step 102, available radio resources are allocated to at least one C-UE and / or at least one D-UE. The radio resources may be resource blocks, preferably PRBs. Radio resources can be allocated by the base station of the cell.

[0111] In the third step 103, according to the angle information of at least one D-UE pair and the angle information of at least one C-UE and / or at...

Abstract

The present invention relates to a radio resource management method 100 for Device-to- Device (D2D) communication in a wireless network, and to a base station 200 for performing this method 100. The method 100 initially determines 101 angle information with respect to a base station 200 for at least one Cellular User Equipment, C-UE 302, and / or at least one D2D User Equipment, D-UE 302, within at least one cell 300 of the wireless network. The method then assigns 102 available radio resources to the at least one C-UE 302 and / or the at least one D-UE 301, and selects 103, for at least one D-UE pair 303, at least one peer UE from the at least one C-UE 302 and / or the at least one D-UE 301 assigned with available radio resources based on the angle information of the at least one D-UE pair 303 and of the at least one C-UE 302 and / or the at least one D-UE 302. Finally, the method shares 104 at least a part of the radio resources assigned to the at least one peer UE with the at least one D-UE pair 303.

Description

technical field [0001] The present invention relates to a wireless resource management method and a base station for managing wireless resources of device-to-device (D2D) communication in a wireless network. Specifically, the present invention addresses interference reduction and resource allocation (RA) in the shared case of D2D communication. Background technique [0002] Besides cellular communication in wireless networks, direct device-to-device D2D communication has been proposed in the prior art. D2D technology exploits the proximity of communication devices to improve cell throughput, energy efficiency, and achievable data rates. Direct D2D communication between D2D user equipments (D2D user equipments, D-UEs) that reuse radio resources of a cellular system is regarded as a key engine of future wireless communication systems and mobile communication systems. [0003] In order to improve the spectrum utilization, as long as the D2D transmission between D-UEs is toler...
