摘要： A computer-implemented method is provided for optimizing positioning performance of a cellular network. The method includes: defining a target area; identifying a set (S) of base station deployment candidate sites (j) within the target area; obtaining, by executing a joint performance optimization routine that jointly optimizes network throughput and positioning performance, wherein a tuning parameter regulates a throughput-positioning ratio of the joint performance optimization routine, active candidate sites as a subset of the set (S) of base station deployment candidate sites (j); and determining the obtained active candidate sites as the sites at which base stations are to be deployed.

摘要： A method for dynamically allocating radio resources across a set of virtualized radio access points (vRAPs) in a virtual radio access network (vRAN) includes collecting contextual information across all vRAPs that share a common carrier bandwidth of a physical radio access point. The method also includes mapping, by a radio resource controller according to an internal mapping policy, the contextual information of the vRAPs into an allocation of vRAN slices to the vRAPs, wherein each vRAN slice comprises allocated computing resources and an allocated bandwidth part (BWP) of the common carrier bandwidth, the BWPs being orthogonal across the vRAN slices. The method also includes notifying the vRAPs of the allocated BWP.

摘要： A method of operating a virtualized radio access point (vRAP) is provided. Transport blocks (TBs) are encoded/decoded by using iterative codes that exchange extrinsic information in each iteration. The exchanged extrinsic information is exploited to infer information about decodability of the data of the TBs.

摘要： A method for classifying vehicles by means of a data processing system according to the nature of their vehicle drivers includes collecting driving data regarding vehicles driving in a predefined local area within a predefined time window, learning a driving policy of one or more vehicles in the local area from the driving data, generating or using a local predictor indicating a prediction of a definable driver behavior over a definable time horizon. The method further shares the local predictor with other vehicles in the local area to provide at least one combined predictor, redistributes the at least one combined predictor to vehicles in the local area, and locally classifies at least one of the vehicles based on the at least one combined predictor and/or the local predictor into a definable vehicle class for providing at least one local classification.

摘要： A method for managing radio and computing resources of a virtualized radio access network, vRAN (40), wherein the vRAN (40) comprises a number of virtualized radio access points, vRAPs (11), sharing a common pool of central processing units, CPUs (12), enhances efficiency and practicability of vRAN resource management. The method comprises dividing, per vRAP (11), a L1 layer processing pipeline (30) into at least one main processing pipelines (50) and into a number of subordinate processing pipelines (51, 52), and coordinating the execution of the pipelines (50, 51, 52) across multiple vRAPs (11). The coordinating includes allocating tasks of the main processing pipelines (50) to dedicated CPUs (12a), and allocating tasks of the subordinate processing pipelines (51, 52) to shared CPUs (12b).
