Downlink Spec. – Downlink Structure: FDD, TDD – Initial Access • Cell Search (PSC, SSC, RS) • System Information Receive (PBCH, PCFICH, PDCCH) • Random Access – Downlink data transmission: PHICH, PDSCH R

Transmit antenna selection(TAS) technology has been adopted for the uplink by the next generation Long Term Evolution wireless standard in order to harness the spatial diversity offered by multiple antennas at the mobile transmitter, while keeping th

CSI feedback allows downlink transmission to be adaptively optimized based on the instantaneous DL channel, so that closedloop beamforming and adaptive link adaptation can be enabled to optimize the system performance. The DL reference sign
