If the UE is to be relayed, the method further comprises indicating, to the UORN, that the UE will be relayed via the UORN; and further comprises: adjusting uplink link adaptation of the UE based on the received information. | 11-13-2014 |
20140355568 | Method and Arrangement for Relaying in Case of Extension Areas Having Uplink/Downlink Imbalance - Underlay network node and macro base station and methods therein for enabling avoidance of interference in a cell extension area associated with an uplink/downlink imbalance. The underlay network node is assumed to be associated with a cell area A, and a cell extension area B, where the cell extension area B has an uplink/downlink imbalance in relation to a neighboring base station and the network node. The method in the underlay network node involves serving a UE in both uplink and downlink when the UE is located in cell area A. The method further involves serving a UE only in the uplink when the UE is located in cell extension area B, thus enabling avoidance of interference related to communication of a UE located in said cell extension area B. | 12-04-2014 |

20150016402 | Transmission Method and Devices in a Communication System with Contention-Based Data Transmission - A method is described for data transmission by user equipments adapted to transmit data using resource blocks allocated by a radio network. The radio network is adapted to allocate resource blocks to a dedicated one of the user equipments or to a plurality of the user equipments. The method comprises the step of allocating at least one of the resource blocks that is not allocated to any dedicated user equipment to a first plurality of the user equipments. The allocation is signaled to the user equipments. A first user equipment of said first plurality obtains data for transmission. At least a first part of the data is transmitted by the first user equipment using said at least one resource block. Devices embodying the invention and methods of operating the devices are also described. | 01-15-2015 |
