METHOD AND SYSTEM FOR SCHEDULING AND MITIGATING CROSS-CELL INTERFERENCE
First Claim
1. A system for scheduling and mitigating cross-cell interference, said system comprising:
- a plurality of network nodes, each having a baseband processor and a transmit antenna, configured to handle multiple input multiple output channels, communicatively coupled with a plurality of co-residents user equipment (UEs);
a central scheduler configured to control scheduling of said plurality of network nodes;
wherein each network node is configured to select a plurality of UEs and provide a short list of UEs to the central scheduler;
the central scheduler in turn identifies a target set of UEs and the co-residents for each network node; and
the network node is configured to pre-select signal-to-noise power to the target UEs without impacting transmission of co-residents UEs.

Abstract
The present invention provides a method and a system for scheduling and mitigating cross-cell interference. The system comprises a plurality of N network nodes, each having a baseband processor and a transmit antenna Nt, capable of handling multiple input multiple output (MIMO) channels, communicatively coupled with a plurality of K co-residents user equipment (UEs); a central scheduler configured to control scheduling of said plurality of network nodes; wherein each network node is configured to select a plurality of UEs and provide the shortlisted UEs to the central scheduler; the central scheduler in turn identifies a target set of UEs and the co-residents for each network node; and the network node is configured to pre-select signal-to-noise power to the target UEs without impacting transmission of co-residents UEs.

7. A method for scheduling and mitigating cross-cell interference, said method comprising:
-
controlling scheduling, by a central scheduler, of a plurality of network nodes, each having a baseband processor and a transmit antenna, and each network node is configured to handle multiple input multiple output channels, communicatively coupled with a plurality of co-residents user equipment (UEs); selecting, by each network node, a plurality of UEs; providing a short list of UEs to the central scheduler; identifying, by the central scheduler, a target set of UEs and the co-residents for each network node based on the short list of UEs provided by the network node; and pre-selecting, by the network node, signal-to-noise power for the target UEs without impacting transmission of co-residents UEs. - View Dependent Claims (8, 9, 10, 11, 12, 13)
