Contribution

The paper proposes a new coded STS scheme with properties like no overhead, no interference, and high coverage, addressing key challenges in femtocell resource management.

Findings

Coded STS has no dedicated resource requirement.

Coded STS effectively eliminates near-far and multi-user interference.

Simulation results demonstrate improved performance of the proposed scheme.

Abstract

Resource coordination and interference management is the key to achieving the benefits of femtocell networks. Over-the-air signaling is one of the most effective means for distributed dynamic resource coordination and interference management. However, the design of this type of signal is challenging. In this letter, we address the challenges and propose an effective solution, referred to as coded single-tone signaling (STS). The proposed coded STS scheme possesses certain highly desirable properties, such as no dedicated resource requirement (no overhead), no near-and-far effect, no inter-signal interference (no multi-user interference), low peak-to-average power ratio (deep coverage). In addition, the proposed coded STS can fully exploit frequency diversity and provides a means for high quality wideband channel estimation. The coded STS design is demonstrated through a concrete numerical example. Performance of the proposed coded STS is evaluated through simulations.
