Abstract
Devices, systems and methods for mitigating the interference introduced by mobile relay nodes in a heterogeneous network are described. The techniques described apply fractional frequency reuse and power controlled beamforming to mitigate such interference.
Claims20
A method, comprising:
- transmitting first communication signals from a relay node to a base station of a donor macro cell over a wireless backhaul communication link;
- and
- transmitting second communication signals from a relay node to a mobile station in the donor macro cell over a radio access link,
- wherein the base station is allocated a frequency bandwidth for communicating with mobile stations, the first communication signals are transmitted over a first portion of the frequency bandwidth and the second communication signals are transmitted over a second portion of the frequency bandwidth, wherein the first and second portions are different portions of the frequency bandwidth.

A node usable in a radio communication system, the node comprising:
- a processor and transceiver configured to
- transmit first communication signals from a relay node to a base station of a donor macro cell over a wireless backhaul communication link;
- and
- transmit second communication signals from a relay node to a mobile station in the donor macro cell over a radio access link,
- wherein the base station is allocated a frequency bandwidth for communicating with mobile stations, the first communication signals are transmitted over a first portion of the frequency bandwidth and the second communication signals are transmitted over a second portion of the frequency bandwidth, wherein the first and second portions are different portions of the frequency bandwidth.
