Performance of In-band Transmission of System Information in Massive MIMO Systems.
IEEE Transactions on Wireless Communications(2018)
摘要
We consider transmission of system information in massive multiple-input multiple-output (MIMO). This information needs to be reliably delivered to inactive users in the cell without any channel state information at the base station. Downlink transmission entails the use of downlink pilots and a special type of precoding that aims to reduce the dimension of the downlink channel and the pilot overh...
