Embodiment Construction

[0027] figure 1 is a schematic overview of a radio communication network. A number of different technologies may be used in the radio communication network, such as LTE, LTE-Advanced, 3GPP WCDMA, GSM / EDGE, WiMax or UMB, to name a few possible implementations.

[0028]The radio communication network comprises a first radio base station 12 and a second radio base station 13 . Each radio base station provides radio coverage over at least one geographical area forming the first cell 14 and the second cell 15 . The first user equipment 10 and the second user equipment 11 are served by a first radio base station 12 in a first cell 14 . The third user equipment 16 and the fourth user equipment 17 are served by the second radio base station 13 in the second cell 15 . When in cellular mode, the user equipment 10, 11, 16, 17 may transmit data in an uplink (UL) transmission over the radio interface to the respective radio base station. The radio base station 12, 13 may transmit infor...

Abstract

Embodiments herein relate to a first radio base station (12) for handling radio interference in a radio communications network, which first radio base station (12) provides radio coverage over a geographical area forming a first cell (14). In the first cell (14) a first user equipment (10) and a second user equipment (11) are served, which first radio base station (12), the first user equipment (10) and the second user equipment (11) are comprised in the radio communications network. The first radio base station (12) determines that a first radio resource is allocated to the first user equipment (10) for communicating over a device-to-device, D2D, connection with the second user equipment (11) within the first cell (14), The first radio base station then transfers information to an arrangement serving a second cell (15), which information identifies the first radio resource and indicates that the first radio resource is allocated to the first user equipment (10) for communicating over the D2D connection with the second user equipment (11) within the first cell (14). The information is to be taken into account by the arrangement serving the second cell (15) for scheduling a second radio resource to a third user equipment (16) in the second cell (15).

Description

technical field [0001] Embodiments herein relate to a first radio base station, a second radio base station and methods therein. In particular, embodiments herein relate to handling radio interference in radio communication networks. Background technique [0002] Many different technologies are used in today's radio communication networks, such as Long Term Evolution (LTE), LTE-Advanced, 3rd Generation Partnership Project (3GPP) Wideband Code Division Multiple Access (WCDMA), Global Communications for Mobile System / Enhanced Data Rates for GSM Evolution (GSM / EDGE), Worldwide Interoperability for Microwave Access (WiMax) or Ultra Mobile Broadband (UMB). The radio communication network comprises radio base stations providing radio coverage over at least one respective geographical area forming a cell. A user equipment is served by and communicates with a respective radio base station in a cell. The user equipment transmits data to the radio base station in uplink (UL) transm...
