20110195719 | Configuration of Nodes for Local Data Transmission Which are Under an Overlay Wide Area Macro Network Operated on the Same Frequency Layer - At a node for local data transmission which is under an overlay wide area macro network operated on the same frequency layer, conditions of a wide area cell of the overlay wide area macro network are obtained, wherein the wide area cell is measured as a cell with a certain received signal level at a location of the node. Based on the conditions of the wide area cell, an allocation of channels for local area data transmission from the node is set such that interference of the channels for the local area data transmission with allocated wide area channels of the wide area cell is avoided or minimized. | 08-11-2011 |
20110242965 | Automatic connection re-establishment using escape carrier - In one exemplary aspect of this invention a method includes receiving at a user equipment from a wide area network access node information identifying at least one predetermined radio frequency carrier; initiating, in response to a presence of an interferer on a radio frequency carrier that is being used for a current connection between the user equipment and the network access node, a connection re-establishment procedure, where the interferer has the potential to cause a radio link failure of the current connection on the radio frequency carrier; and transmitting a connection re-establishment request to the network access node on the predetermined radio frequency carrier. The interferer can be a closed subscriber group network access node that the user equipment is not authorized to gain access to. | 10-06-2011 |
20110250881 | Apparatus, Method, System and Program for Power Control or Power Setting - Embodiments provide an apparatus, method, product and storage medium for controlling or setting a transmit power of a femto cell depending on a received power of at least one neighbouring macro cell. | 10-13-2011 |
20120202490 | Method and Apparatus for Determining a Time Interval at an Access Node for Radio Measurements - A method includes determining at least one time interval for an access node of a group of neighboring access nodes. The at least one time interval is one in which said access node has substantially no transmission and one or more other access nodes of said group transmit. The method further includes performing, by said access node, radio measurements in said at least one determined time interval of said one or more other access nodes of said group which transmit and configuring radio resources in dependence on said radio measurements. | 08-09-2012 |
20120252524 | Uplink Power Control for Lower Power Nodes - A method and an apparatus are described, in which a transmission power related parameter used for determining an uplink transmission power for a first cell based on the relational parameter, which indicates a relationship between the first cell and the second cell. | 10-04-2012 |
20130100836 | Allocating One or More Resources (e.g. carriers) to a Network Element (e.g. HeNB) in a Communication System - A method of allocating one or more carriers such as frequencies, to a network element (e.g. HeNBs) in a communication system, in particular a heterogeneous communication system including selecting at least one neighbouring network element (e.g. a macro base station), measuring a parameter (e.g. RSRP) from the one neighbouring network element; determining whether said parameter is above a threshold; and allocating carrier(s) to said network element as a result. | 04-25-2013 |

20130136057 | Base Station Aided Synchronization - An apparatus, method and computer program product include requesting a physical identifier of a communication base station having a preset hierarchical distance to a communication core network from a first communication base station having a higher hierarchical distance than the preset hierarchical distance, based on a connection on one of an interface between a communication base station having a higher hierarchical distance than the preset hierarchical distance and the communication core network and an interface between two communication base stations both having a higher hierarchical distance than the preset hierarchical distance. Prior to the requesting, an initial synchronization with a neighbor base station can be established. After the requesting, an accurate synchronization with the overly base station based on the obtained physical identifier can be established. | 05-30-2013 |
