摘要:LTE and LTE-Advance communication are based on the uplink reference signals to estimate the channel characteristics. A split transmission of sounding and demodulation signaling will cause many constraints; such as layers and reference signal symbols interferences, increase in delay and reduction in the overall throughput of the LTE uplink transmission. In this paper, we propose an energy efficient LTE uplink transmission by eliminating the demodulation reference signal (DM-RS) information from the LTE uplink resource grid. Initially, the DM-RS signaling data is eliminated from the data resource grid to provide spare capacity for data to increase the data rate within the same energy consumption. After that, the DM-RS signaling information within SRS signaling symbols is amalgamate. Finally, the model of single value sounding reference signal (SV-SRS) is designed to merge the DM-RS features in SRS symbols, which are helpful to estimate the fine channel parameters for LTE downlink transmission. SV-SRS also overcomes the symbols and channel interference to enhance the overall throughput and reduces the BER of LTE uplink system. The simulation results of proposed strategy show that the SV-SRS improvement in the LTE uplink data by eliminating the DM-RS symbols.
