摘要:
The disclosure relate to interference coordination in wireless communications. A first level station can obtain information for interference coordination with a second level station to protect the second level station from interference in arrangement where the second level station provides a smaller coverage area than the first level station and is at least partially located in the area of the first level station. Use of directional antenna beams by the first level station and/or communications by the second level station can then be controlled accordingly.

A method, apparatus, and computer program for authenticating a newly activated local area base station in a cellular network is presented. The newly activated local area base station, associated with a sub-cell located within a coverage area of a wide area base station of a cellular telecommunication system, is paired with the wide area base station on the basis of information enabling identification of the wide area base station and originating from the local area base station. Then, transfer of a radio communication identifier to the local area base station is arranged over a wired connection.

Methods and apparatus for mobility control are disclosed. A network entity can generate information promoting at least one cell for selection by at least one mobile device and associate the information with at least one physical cell identity available for selection. The information is then communicated to the at least one mobile device. The at least one mobile device can then take the information into account in cell selection.
摘要:
In a communication network including a plurality of base stations, a method including the steps of: sending a signal from said base station indicating that it will enter a period of inactivity, to at least one other base station; storing at that least one current parameter(s) relating to interference between base stations and/or updating said parameter(s) for forward use. The parameter(s) may relate to interference between first base station and at least one operationally neighboring base station and may be Background Interference Matrix (BIM) data.

Furthermore, a communication system is suggested comprising said device.
摘要:
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.
摘要:
Methods and apparatuses for coordinating muting in a system including radio service areas of a first type and of a second type are disclosed. In a method a node providing a radio service area of the first type detects a first radio service area of the second type and determines information suitable for determining the location of the node. Said information for identifying the first radio service area and said information suitable for determining the location of the node are communicated to a controls apparatus. Upon receipt of said information for identifying and information suitable for determining the location of the node the control apparatus can coordinate muting based on the received information.
摘要:
A method, user equipment, network device, and software product enable a user equipment to determine that at least one of several triggering criterion have been met, in which case the user equipment provides a power control headroom report on an uplink from the user equipment. The triggering criterion includes a threshold having been reached, and the threshold is adjustable via a signal to the user equipment from a base station (such as an eNodeB).

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.
摘要:
An apparatus, method, system and computer program product is configured for avoiding base station self-interference due to transmit intermodulation in carrier aggregated communication systems. Physical downlink communication channels are allocated to respective component carriers per time interval according to a communication service in which communication is performed on an aggregation of component carriers of one or more frequency band such that component carriers to be used for transmission are separated from component carriers to be used for receiving by a transmit-receive-frequency gap band. However, not all available component carriers to be used for transmission are allocated in the same time interval. Rather, in each time interval, the physical downlink communication channels to be allocated for transmission are allocated to the available component carriers to be used for transmission such that, in each frequency band, the overall emission spectrum does not reach beyond the transmit-receive-frequency gap band.
