Cell Configuration and Channel Configuration during Call Processingįollowing is the over protocal sequence being exchanged between UE and Network.Channel Mapping Table throughout Call Processing.I hope you can get the big picture of LTE call flow and take this page as a framework (or motivation) to study LTE. In this page, I would touch mainly on overall channel structure and RRC/NAS signaling to establish a basic LTE call setup. So putting all the details of the call processing in this one page is impossible. Understanding a complete a call processing steps means understanding everything about the technology. This will be the backbone structure for all other call processing.įollowings are the topics to be explained in this page. In the case of a 2×2 MIMO antenna system, the two transmitters send different parts of the same data stream simultaneously, while the receivers have to piece them back together.In this section, I will go through a typical protocol sequence of LTE packet call. The E-UTRA also uses the MIMO technology and enables the simultaneous support of more users and a lower processing power required for each UE. Its main advantage is a lower peak-to-average power ration, which is proven to be more efficient in networks where the transmit power is most important. SC-FSMA is also a frequency division multiple access scheme and usually represents and alternative to OFDM. OFDM handles phenomena such as interference, noise or multipath significantly more efficiently than other modulation methods. OFDM splits data into small sub-carriers on neighboring frequencies, over a single channel. The E-UTRA uses Orthogonal frequency-division multiple access (OFDMA) in the downlink and Single-Carrier Frequency-Division Multiple Access (SC-FDMA) in the uplink. The E-UTRA enables a latency decrease, allows high bandwidth capabilities and is optimized for packet data. The E-UTRA is the air interface of an LTE network and is the equivalent of he UTRA air interface in UMTS networks.
