A sounding method in a cellular wireless communication system, comprising at least one mobile station and at least two base stations. One base station is a serving base station for the mobile station and the at least one further base station is a neighboring base station. The serving base station generates a schedule for measurement signals and transmits said schedule to the mobile station and to the neighboring base station. The mobile station transmits measurement signals in accordance with the schedule to the serving base station and to the neighboring base station. Furthermore, the neighboring base station calculates a mean channel state for the uplink channel from the mobile station to itself and transmits the mean channel state to at least one further base station, so that said base station can be provided with channel estimations for uplink channels between the mobile station and all base stations.

Measurement in radio communication systems

Various exemplary embodiments relate to a method and server for processing geo-information including receiving, at the Geo-Information System server, a geo-view identifier; sending an indication whether a geo-view identified by the geo-view identifier is available, the geo-view comprising a schema identifier, wherein a schema identified by the schema identifier describes a data format comprising location information and one or more characteristics of the conditions in the cellular network; receiving data in a format consistent with the identified schema; and storing the received data in a data store.

Radio access network geographic information system with multiple format

The present invention relates to a method and apparatus for optimizing radio coverage and power consumption within a mobile communication network (). In accordance with an embodiment of the invention, radio measurements (UE_meas; BS_meas; BS_meas) carried out by subscriber devices () and/or radio base stations (), as well as user geographical locations (UE_pos; UE_pos; UE_pos) at the time the radio measurements have been carried out, are gathered. Antenna geographical locations (ant_pos; ant_pos) are then derived from the radio measurements and the user geographical locations, and radio propagation models (rpm; rpm) from the antenna geographical locations that best fit the radio measurements at the user geographical locations. The so-derived radio propagation models from the so-derived antenna geographical locations are then supplied to a radio resource controller () for activation of dormant cells (C; C).

Network analysis for radio resource activation in green mobile networks

The present invention relates to a method for reducing interference in the downlink direction of a cellular radio communication system comprising base stations communicating with terminals using a frame structure showing a time and frequency extension, said frame comprising a preamble portion and at least one data portion, said terminals being adapted to receive frames for which the receive power of said at least one data portion is varying in a predefined range relative to the receive preamble power of said preamble portion, According to the present invention, the method comprises the steps of:

Method for reducing interference in the downlink direction of a cellular radio communication network and corresponding base station

The invention relates to a method for mesh-wide capacity management in a mesh network (), in particular comprising mesh links () of different link technologies/with different local properties, the method comprising: signalling from at least one link resource manager associated with a mesh link () or a group () of mesh links of the mesh network () to at least one network capacity manager () information about a calculation model to be applied for calculating at least one flow performance characteristics, in particular a resource consumption, for establishing at least one packet-based traffic flow on the mesh link () or on the group () of mesh links. The invention also relates to a link resource manager, to a network capacity manager (), to a signaling system, and to a mesh network ().
