20140135008 | Method and System for Mobile Relay Enablement - A method and relay node for managing a relay node that is moving relative to a source network node, the method receiving parameters of a target network node from a source network node at the relay node; initiating a direct attachment of the relay node to the target network node; and detaching the relay node from the source network node. Also, a method and network node for managing a relay node that is moving relative to a source network node, the method sending a handover request of a relay node from the source network node to a target network node; performing handover of a plurality of user equipments (UEs) from the source network node to the target network node, wherein the plurality of UEs are attached to the relay node, and establishing an interface between the relay node and the target network node. | 05-15-2014 |
20140169279 | HIDDEN NODE INTERFERENCE ISSUE IN A TYPE II RELAY NETWORK - Devices and methods are provided for managing hidden node interference. A communications session between a client node and an access node is affected by interference generated by a hidden relay node. The victim client node and the aggravator relay node are identified by the access node. The access node generates a set of scheduling instructions, which are then provided to the client node. The client node then uses the scheduling instructions to avoid further interference. | 06-19-2014 |
20140211724 | User Equipment Component Carrier Allocation - A method for configuring at least one component carrier (CC) for a physical downlink shared channel (PDSCH). The method includes receiving a CC configuration using a signaling protocol, wherein the CC is assigned using a semi-static configuration. Also included is a user equipment (UE) comprising a processor configured to receive a CC configuration for at least one CC for a PDSCH using a signaling protocol, wherein the CC is assigned using a semi-static configuration. Also included is an access node comprising a processor configured to transmit a CC configuration for at least one CC for a PDSCH using a signaling protocol, wherein the CC is assigned using a semi-static configuration. | 07-31-2014 |
