Abstract
A method for reducing a memory requirement in an uplink receiver using a Sounding Reference Signal (SRS) channel along with a Demodulation Reference Signal (DMRS) for channel estimation in SC-FDMA/OFDM based radio access technologies is provided. The method includes (i) requesting the Sounding Reference Signal (SRS) and receiving the Sounding Reference Signal (SRS), by a base station, from at least one user device and performing corresponding channel estimation, (ii) scheduling, by the base station, at least one of a data or control channel transmission, and (iii) demodulating, using a SC-FDMA/OFDM demodulator, received SC-FDMA/OFDM symbols that corresponds to at least one of the data or control channel transmission scheduled by the base station and saving the demodulated SC-FDMA/OFDM symbols for one DMRS interval in a buffer until channel estimation is ready, thereby reducing the memory requirement of the uplink receiver.
