DOWNTILT SELECTION IN A FULL DIMENSIONAL MULTIPLE-INPUT MULTIPLE-OUTPUT SYSTEM |
摘要 |
A technology for an enhanced node B (eNode B) in a cellular network that is operable to determine downtilt using full dimensional (FD) multiple-input multiple-output (MIMO). A plurality of orthogonal frequency division multiple access (OFDMA) signals can be transmitted, wherein each transmitted OFDMA signal is transmitted with a selected downtilt angle from a two dimensional antenna array of the eNode B. Reference signal received power (RSRP) feedback information can be received from a UE for each of transmitted OFDMA signals at the selected downtilt angles. Received signal strength indicator (RSSI) feedback information can be received from the UE. A reference signal received quality (RSRQ) can be calculated for each of the selected antennas angles using the RSRP feedback information and the RSSI feedback information. A downtilt angle can be selected for transmitting data from the eNode B with a highest signal to interference plus noise ratio (SINR). |
