Due to the requirement of high capacity to access broadband service as well as high spectrum efficiency, the frequency reuse of one is targeted to be applied in LTE network planning. But it can lead to a worse inter-cell interference levels experienced especially by users located at the cell edge area. Soft Frequency Reuse (SFR) is considered as an effective frequency reuse scheme for inter-cell interference...
Different standardization bodies are working towards test methodologies and procedures to determine true Multiple Impute Multiple Output (MIMO) performance. A reference CTIA (Cellular Telecommunications and Internet Association) 2×2 Long Term Evolution (LTE) MIMO antenna concept has been designed [1–2] and verified [3] to eliminate the uncertainties linked to the unknown antenna performance of the...
This letter proposes an efficient low-complexity scheduler to virtualize the wireless resource blocks (RBs) and share them between users of multiple mobile network operators (MNOs). The scheduler aims at maximizing the throughput while maintaining access proportional fairness (APF) among users as well as MNOs. Normalized signal-to-noise ratio (SNR) selection criterion is used to impose APF between...
As a breakthrough technology under 3GPP, LTE has attracted attention worldwide. Main features include enhanced peak data rates, lower delay, increased cell edge throughput. For an LTE system, serving a large number of users requires an efficient RRA algorithm which has not been standardized for the system and is still an open end for development. Researchers have proposed various algorithms some of...
In this paper we address the challenge of multiuser scheduling in the downlink of 3GPP UMTS/LTE. Long Term Evolution (LTE) imposes the constraint of using the same code rate, modulation order and transmit power for all resources a User Equipment (UE) is scheduled onto. This, in addition to the lack of channel knowledge, prohibits theoretical concepts such as capacity maximization to be applied for...
