A computer-implemented method and a server for device positioning. The computer-implemented method includes receiving a control message from a positioning server. The control message indicates a set of channels associated with an area and time periods for monitoring the set of channels. At least one measurement of a signal from at least one of a reference device for the area and a target device is obtained, according to the control message, with the reference device being located at a predefined position with respect to the area. The at least one measurement is reported to the positioning server for determining a position of the target device with respect to the area.

Device positioning

Methods, computer systems and computer program products for service packages porting are provided. Aspects include a computer implemented method for a service package porting is provided. One or more processors provision a component of a first layer based on a plurality of component descriptions and build the service package on the first layer. Hence the one or more processors collect first log information that relates to build failures of the service package. According to another embodiment of the present invention, the method further comprises determine whether a build failure is related to the first layer based on the first log information and remove the component of the first layer if it is determined that the build failure is related to the first layer.

Log-based software porting

A computer-implemented method uses a predictive time-sequence model to adapt hardware configurations at run-time for an application including multiple stages of execution. At each stage a system monitor is started at the launch of a first task in a first run to collect performance data. The system monitor is stopped at the completion of a last task in the first run, then a predictive optimal configuration is computed and applied to the remaining runs in the stage.

Adaptive hardware configuration for data analytics

A computer-implemented method and a server for device positioning. The computer-implemented method includes sending a control message to a detector. The control message indicates a set of channels associated with an area and time periods for monitoring the set of channels. A measurement of a signal from a device for the area and a target device is received from the detector. Position of the target device with respect to the area is determined based on a measurement and a radio map. The radio map indicates signal strength corresponding to positions in the area.

A method for processing interference in wireless communication at a base station, wherein at least some of a plurality of (Radio Frequency) RF channels in the base station operates at a current operating frequency point assigned to the base station includes detecting interference of one or more candidate frequency points by using at least one RF channel, wherein the one or more candidate frequency points are different from the current operating frequency point; reporting result of detecting interference of the one or more candidate frequency points to a resource manager; and in response to the resource manager assigning one of the one or more candidate frequency points to the base station, notifying a user to switch from the current operating frequency point to the assigned candidate frequency point.

Interference processing in wireless communication

An apparatus for sharing frequencies in an orthogonal frequency-division multiplexing OFDM-based wireless communication system, wherein the OFDM-based wireless communication system comprises a base station and a mobile device that work within a radio frequency band, the method comprising: detecting an interference signal in the radio frequency band; setting by the base station, based upon the interference signal, interference indication information in a control header of a downlink frame to be sent to the mobile device, the interference indication information indicating a frequency range that is occupied by the interference signal in the radio frequency band; and sending by the base station the downlink frame to the mobile device, such that the mobile device may, based upon the interference indication information, avoid the frequency range where the interference signal is located.

Sharing frequencies in an OFDM-based wireless communication system

An apparatus for wireless positioning includes a first delimitation unit configured to delimit an initial boundary for a predetermined space to divide the predetermined space into at least two areas, each area of the at least two areas comprising multiple zones, the multiple zones including a boundary zone adjacent to the initial boundary; a detection unit configured to detect signal feature values of respective wireless access points in the boundary zone and determine an identifier set of the detected wireless access points; and a second delimitation unit configured to re-determine the boundaries of the at least two areas for the wireless positioning based on the detection results in the boundary zone. With the method and apparatus of embodiments of the present invention, it is possible to reduce the positioning calculation time while maintaining high positioning accuracy.
