• Overall DL transmission bandwidth
• Number of transmit antennas
• DL-RS Transmit Power
• System Frame Number, etc Transmitted in
• Time: subframe 0 in every radio-frame
– 4 OFDM symbols in the subframe
• Frequency: middle 1.08MHz (6 RBs)
TTI = 40 ms
• Transmitted in 4 bursts at a very low data rate Transmission such that
• Every burst is self-decodable
• CRC check uniquely determines the 40ms PBCH TTI boundary
