Abstract: In some embodiments, a computing system maintains, in a memory, information on one or more terminal devices, a dictionary of beams and information on a spatial grid. The computing system maps each terminal device to the spatial grid based on up-to-date results of radio measurements and calculates, for each spatial element, a load caused by the one or more terminal devices based on the mapping. The computing system evaluates, for each combination of a beam and a terminal device, a reference signal received power, RSRP, based on results of the radio measurements. The computing system calculates a first map of expected spatial distribution of traffic based on the calculated loads and beam-specific second maps of expected RSRP based on the values of the RSRP. Finally, the computing system causes performing beamforming optimization based on the first map and second maps.

Abstract: Methods and apparatus for realizing dynamic point selection improve the cell-edge throughput and geometric mean of release 8/9 UEs. The method comprises a step of receiving estimated channel quality reported by all the TPs in the CoMP set, a step of switching the serving TP for the UEs based on the estimated channel quality and/or cell load, a step of forwarding the scheduled data from the primary TP to the serving TP, a step of separately transmitting PDCCH to the UEs by the primary TP and transmitting PDSCH to the UEs by the serving TP. the implementation of the method and apparatus improves the cell-edge throughput and geometric mean of UE throughput by serving UEs instantaneously from the cell that provides better throughput accounting for fast time-scale channel fluctuations and/or load. It helps in reducing interference due to data getting drained faster when users are served from cells with better channel conditions.

Abstract: There are provided measures for inter-cell interference coordination in heterogeneous networks. Such measures exemplarily include determining a strongest interfering macro cell access node, said strongest interfering macro cell access node operating in time based subframes, wherein said subframes include almost blank transmission subframes during which said strongest interfering macro cell access node is muted and active transmission subframes during which said strongest interfering macro cell access node is transmitting, reporting said strongest interfering macro cell access node, and receiving a transmission in a subframe, wherein a control parameter of said transmission is set based on whether said subframe corresponds to an almost blank transmission subframe of said strongest interfering macro cell access node or to an active transmission subframe of said strongest interfering macro cell access node.

Abstract: Embodiments of the present disclosure relate to compressed channel state information transfer. According to embodiments of the present disclosure, the radio unit at the base station receives signals from the terminal device. The radio unit (RU) compresses the signal based on the weights of beams and transmits the compressed signal to the baseband unit (BBU) at the base station. The baseband unit reconstructs the channel based on the compressed signal and the coefficients. In this way, the amount of information conveyed across the RU-BBU interface is reduced, and the accuracy of channel estimation is improved. Further, the sounding reference signal (SRS) channel can be obtained at the BBU with reduced number of SRS transmissions.

Abstract: A solution for allocating N radio beam configurations to access nodes including, in some embodiments, a method comprising storing a beam library defining a set of radio beam configurations for a coverage area. A coverage area is divided into sub-areas, and a set of channel quality metrics is collected, as is a traffic density parameter for each sub-area. The following steps are performed: selecting N radio beam configurations from the set of radio beam configurations; mapping each sub-area with one of the selected N radio beam configurations; computing a service performance for the selected N radio beam configurations; the service performance is weighted by the traffic density parameters. The service performance are stored as linked to each radio beam configuration of the selected N radio beam configurations. Based on the stored service performances, a set of N radio beam configurations is selected and the N radio beam configurations are allocated.
