A system () for obtaining samples for a dynamic resource management system in a wireless network is configured to analyze () data for a dynamic resource management system to determine one or more combinations of input values which are not present or underrepresented in the data. The dynamic resource management system uses supervised learning to estimate resource demand. The system is further configured to adjust () one or more flow characteristics of a data flow between a user device and a base station to obtain one of the combinations of input values, determine a quantity of resources used for the data flow and actual state and/or cell characteristics relevant to the data flow, create a new sample based on the used quantity of resources, the adjusted flow characteristics, and the actual state and/or cell characteristics, and store the new sample in the data.

Obtaining samples for learning-based resource management by adjusting flow characteristics

A first method comprises transmitting data () of a first kind during a first part of a first time slot (ti) of a plurality of time slots (ti-ti) of equal length according to a regular slot schedule, transmitting a preamble () in a second part of the first time slot, and transmitting data of the second kind during one or more mini-slots of a first part of a second time slot (ti) of the time slots according to a mini-slot schedule. The second time slot succeeds the first time slot and the first part of the second time slot comprises a plurality of mini-slots (). A second method comprises receiving the data of the first kind during the first part of the first time slot, receiving the preamble in the first time slot, and receiving data during a plurality of the mini-slots of the second time slot.

A method of scheduling transmissions to client devices comprises receiving feedback (f1a-f3d) about a plurality of candidate downlink frequency resources (-) from a plurality of client devices and/or measuring channel qualities of a plurality of candidate uplink frequency resources (-) from receptions of transmissions, e.g. of the feedback, by the plurality of client devices. The method further comprises selecting a subset () of the plurality of candidate downlink frequency resources and/or a subset () of the plurality of the candidate uplink frequency resources based on the received feedback and/or the measured channel qualities. The method further comprises scheduling transmissions (dd1-3) to the client devices on the selected subset of candidate downlink frequency resources and/or transmissions (ud1-3) from the client devices on the selected subset of uplink frequency resources.

A receiving system () is configured to determine reception antenna weights for a plurality of antennas and/or antenna elements for each transmitting system of a plurality of transmitting systems (-) for receiving wireless signals using receive beamforming. The receiving system is further configured to determine a schedule for receiving the wireless signals. The schedule indicates a resource allocation for each of the transmitting systems. The resource allocation specifies an allocated time period. The receiving system is also configured to inform each transmitting system of the resource allocation and, for each resource allocation in the schedule, receive a plurality of instances of a wireless signal via the antennas and/or antenna elements and combine the instances by using an antenna configuration which is based on at least reception antenna weights determined in relation to a transmitting system associated with the resource allocation.

Scheduling reception of wireless signals using receive beamforming

The invention relates a method and system for assessing coverage of a wireless access network within a desired area via cooperating wireless access networks and terminals capable of measurement and reporting across the different wireless access networks. The cooperation refers to, among other things, the ability of obtaining coverage assessment for one of the wireless access networks using results of the measurements collected at one of the other wireless access networks. In this manner, more accurate and complete coverage assessment may be obtained, relative to the prior art approaches.

The invention relates to a method for activating at least one inactive cell in a wireless telecommunications infrastructure. The telecommunications infrastructure comprises an active cell containing a plurality of terminals. A presence signal is transmitted in the at least one inactive cell. The plurality of terminals in the active cell detect the presence signal(s) of the one or more inactive cells to gather information from the inactive cell. The information is reported to and received at the telecommunications infrastructure. The information received from the plurality of terminals is processed in a processing system of the telecommunications infrastructure to provide a processing result. The inactive cell is activated when the processing result fulfills at least one activation condition such that at least one of the plurality of terminals is within a coverage area of the activated cell.

A mechanism to handle conflict situations relating to configuration parameter value changes that can be made by two or more different self-organizing network functions is provided. The mechanism is based on storing and maintaining at least short term history information on configuration parameter value changes () and utilizing the history information to determine whether or not to allow a configuration parameter value change.

Conflict handling in self-organizing networks

The invention relates to a method for deactivation of at least one first cell of a plurality of cells in a telecommunications network. User devices in the at least one first cell are triggered to report measurement information regarding one or more second cells of the plurality of cells to the telecommunications network. The measurement information is received in the telecommunications network and analyzed in order to determine whether one or more user devices in the at least one first cell are eligible for being served by a second cell of the one or more second cells when the at least one first cell would be deactivated. When the one or more user devices are determined to be eligible for being served by the second cell of the one or more second cells, the one or more user devices are transferred and the at least one first cell is deactivated.
