Abstract: 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.

Abstract: A network element for a communication network, wherein the network element includes an input interface adapted to receive a measurement report associated with a further network element, wherein the measurement report includes an identifier value identifying the further network element and a first value of a characteristic feature, and a comparing unit adapted to compare the first value with a second value of the same characteristic feature stored for said identifier value in the network element. Furthermore, the network element includes a signal generating unit adapted to generate a signal in case the comparison of the first value and the second value indicates that an appropriately defined distance between the first value and the second value is above a predetermined threshold.

Abstract: 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.

Abstract: A technique of determining whether or not to limit the wireless transmission power of a first access node serving a first area within a second area served by a second access node, wherein the first and second access node share at least some frequency resources; wherein the determining is based on an indicator of the number of other access nodes operating within a predetermined range of said first access node that also share at least some frequency resources with said second access node and serve further areas within said second area.

Abstract: There are provided measures for proximity reporting procedures in radio access, for example in heterogeneous network environments, said measures exemplarily including sending, to a serving base station representing a source of mobility of a user equipment, a first proximity indication indicating proximity to a microcell base station representing a target of mobility of said user equipment, said first proximity indication including a carrier according to a preceding access of said user equipment to the microcell base station, and, when detecting the microcell base station on said carrier according to the preceding access fails, sending, to the serving base station, a second proximity indication indicating proximity to the microcell base station, said second proximity indication including a carrier being different from said carrier according to the preceding access. Said measures may exemplarily be applied for mobility procedures in LTE, LTE-Advanced, HSPA and/or UMTS radio access systems.

Abstract: 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.
