Cognitive Interference Management in Wireless Networks with Relays, Macro, Micro, Pico and Femto Cells

Technology:Interference Management in wireless network;Industry: IT, Automotive, Healthcare, Aerospace & Defense;

Application: Telecommunication, & etc.

Market: The global wireless networking market is projected to grow $132.9B by 2027 at a CAGR of 12.8% during (2020-2027);+

In present era, a wireless network includes one or more base stations that provide services to a coverage area and two main challenges of wireless network operator would be to improve network coverage, & throughput of the cellular systems.
Further, there was many user equipment like relay stations used by the operator to improve the capacity or coverage however the throughput minimizes.
There are many techniques are discussed, which suffers congestion of resource, complex route and time delay, high interference & reduced system throughput including other issues.
Hence, there is a need to address above issues.

Present invention describes a method for interference management in heterogeneous/homogeneous communication networks.
The communication networks comprise one or more Base stations(BS), Relay stations(RS), Femto Base Stations(FBS), Pico Base Stations(PBS) & Micro Base Stations(MBS) depicted in figures.
The method provides a technical solution which is discussed herein & shown in figures.
1ststep states that performing interference measurements for a specific group of said RS, FBS, PBS, & MBS and said UE sending said interference measurement to a serving BS;
2nd step states that classifying each of the UEs as either a victim UE of said BS, RS, FBS, PBS, & MBS or as a safe UE based on the measurement received from said UEs;
3rd step states that sending a list of victim UEs to each of said BS, FBS, PBS, & MBS & said RS either receiving a list of its victim UEs from said serving BS or from uplink (UL) signalling; and
4th step states that performing resource allocation for said UEs of said BS, FBS, PBS, & MBS.

Technical Perspective:

The subject Patent discloses a method to enable dynamic distributed resource allocation for interference management for the access link of one or more BS, RS, FBS, PBS, MBS in a heterogeneous/homogeneous communication networks.

Industrial Perspective:

The network has minimal centralized controller entity.

Adapted to have resources allocated by the scheduler for access link of each BS, RS, MBS, FBS, PBS can be partially/completely orthogonal in time, and/or code and/or space.
