Assessment of LTE Uplink Power Control With Different Frequency Reuses Schemes
Single Carrier Frequency Division Multiple Access (SC-FDMA) is the access scheme chosen by 3GPP for uplink UTRAN Long Term Evolution project (LTE). As SC-FDMA provides intra-cell orthogonality, one of the main reasons for performance degradation is the Inter-Cell Interference (ICI). This degradation is accentuated by the frequency reuse of 1 deployed in the system, Since the Frequency Reuse (FR) and Power Control (PC) functionalities is a strong tool for co-channel interference mitigation, using them critical issues in cellular Orthogonal Frequency Division Multiple Access (OFDMA)/LTE networks. In this paper, the authors compare between the Open Loop Power Control (OLPC) and Closed Loop Power Control (CLPC) performance using different frequency reuse schemes.
