摘要： A method for operating a centralized radio access network (C-RAN) having a plurality of base stations, wherein at least a portion of base station processing is performed at a centralized processing entity, and wherein a virtualized environment is provided by the centralized processing entity such that the plurality of base stations run in virtual machines, includes relocating base station processing from a first virtual machine that performs base station processing for a first base station that serves an initial cell to a second virtual machine by: introducing a target cell for which the second virtual machine performs base station processing, simultaneously transmitting, via at least a portion of antennas of the first base station, signals for both the initial cell and the target cell, and handing over user terminals that are assigned to the initial cell to the target cell.

摘要： A method for operating a distributed base station includes performing Hybrid Automatic Repeat Request (HARQ) processing. The distributed base station comprises a centralized processing entity and distributed remote radio access points, which are coupled to the centralized processing entity via a backhaul connection. The HARQ processing is performed locally by the remote radio access points, by performing an assessment a quality of received data and/or current radio conditions. Based on the assessment, it is decided locally on a necessity of re-transmissions without decoding the received data at the remote radio access points.

摘要： A method and system provides for adapting a computational load in a partly centralized radio access network. A computational load of computational elements of a central processor is measured or estimated, which central processor communicates with a plurality of radio access points and user equipment in the partly centralized radio access network. It is determined, by the central processor, whether the computational load should be reduced or increased. The computational load is adjusted by changing at least one of a modulation and coding scheme of the user equipment or an uplink power.

摘要： A method for operating a mobile communication network includes identifying link processing jobs running on one or more entities in the mobile communication network which cause an increase of data transmission delay in a communication link between the radio access network and a core network of the mobile communication network. One or more of the identified link processing jobs is selected. Link parameters of the selected link processing jobs of the communication link are adapted depending on latency requirements of a service using the communication link.

摘要： A method of managing Radio Access Network (RAN) processing within a data center of a centralized radio access network (CRAN), wherein the data center comprises a plurality of compute resources that perform at least part of the RAN processing of a plurality of connected remote radio access points, includes assigning, to packets from the plurality of remote radio access points, an identification information that originates from the RAN; deciding, by schedulers based on a scheduling algorithm, on which of the compute resources processing of the packets is to take place; and using the identification information to route the packets within the data center. The compute resources are implicitly addressed through the identification information.
