Abstract: The present invention relates to a computer-implemented method of resource allocation for multiple virtualized base stations, vBSs (420), deployed in a shared radio computing platform (410), wherein the vBSs (420) share the same Radio Unit, RU (430), having a fixed number of Physical Resource Blocks, PRBs. With respect to an efficient utilization of both radio resources and available computing resources, the method comprises obtaining, by a radio controller, a set of metrics from the radio computing platform (410) for each of the vBSs (420) deployed; learning, by a learning agent (450) of the radio controller based on the obtained set of metrics, the traffic patterns and the CPU consumption of the vBSs (720) deployed; and computing, by the radio controller based on the knowledge of current CPU set configurations of the vBSs (420) and based on the learned traffic patterns and the CPU consumption of the vBSs (420), a CPU set configuration, L3 cache allocation and PRB assignment for each vBS (420) in such a way that at least one of the overall CPU overhead, the decoding time and SLA violations are minimized.

Abstract: 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).

Abstract: Embodiment of the invention provide a method for determining a UE location within a cellular radio network, wherein the network includes at least one reconfigurable intelligent surface, RIS (220; 320). To achieve a high accuracy of UE location estimation without requiring any a-priori knowledge of the UE position and without requiring any reception mode enabled RISs deployment, the method comprises executing a beam-alignment procedure (312) at a base station, BS (210; 310), of the network; identifying, based on the results of the beam-alignment procedure (312) and given the position of the at least one RIS (220; 320), an optimal BS-RIS beam configuration; fixing the optimal BS-RIS beam configuration at the BS (210; 310) and executing a beam-alignment procedure (332) at the at least one RIS (220; 320); performing power measurements at the UE (220;320) both during the beam-alignment procedure (312) executed at the BS (210; 310) and the beam-alignment procedure (332) executed at the at least one RIS (230; 330); and determining the UE (220; 320) position based on the results of the power measurements.

Abstract: The present invention relates to a virtualized radio access point, vRAP, as well as to a method of operating the same. With regard to enabling high-performing DU virtualization in order to maximize performance in cloud-based virtualized RANs, the vRAP comprises an encoder/decoder configured to encode/decode transport blocks, TBs, by using iterative codes such as turbo codes or LDPC codes that exchange extrinsic information in each decoding iteration; and a digital signal processor, DSP, pipeline configured to infer information about the decodability of the data of the TBs by exploiting the exchanged extrinsic information.

Abstract: Embodiments of the invention provide a pipeline design to process 4G LTE and 5G New Radio (NR) physical layer workloads in sub-6GHz frequency bands over cloud platform. The composition of the pipeline (i) maximizes performance by exploiting multi-core clouds efficiently; and (ii) attains high resiliency by guaranteeing a minimum viable subframe (MVSF) irrespective of the computing availability and demand. Hence, the pipeline is particularly suited for constrained (low-cost) computing infrastructure and/or when the infrastructure is heavily shared, inducing variability on the availability of resources.
