Multiple-input multiple-output (MIMO) system with a large number of antennas (i.e., massive MIMO) at the base station (BS), has been investigated to improve spectral efficiency. In Massive MIMO systems, downlink channel state information (CSI) is needed at base station (BS) to calculate pre-coding weight for downlink spacial multiplexing of multiple users. In time division duplex (TDD) scheme, uplink channel estimate can be utilized for downlink precoding thanks to channel reciprocity between up and downlink. In this paper, we propose a two-dimensional pilot allocation scheme for channel estimation in massive MIMO/TDD system, where two-dimensional pilots over frequency and delay-time domains are allocated to each user for their uplink channel estimation. We evaluate bit error rate (BER) performance of massive MIMO/TDD system using the proposed pilot allocation by computer simulation and clarify the effectiveness of the proposed pilot allocation. |
