We 4G/LTE - DCI DCI When you study the physical frame structure of LTE, you may be impressed by flexibility (meaning complexity in other way) of all the possible 4G/LTE - DRX eDRX (Extended/Enhanced DRX) I assume that you already know what DRX (Discontinuous Reception) mean. And when you think of 4G/LTE - BL/CE Paging Overall Paging mechanism for LTE BL/CE is similar to legacy LTE. In MIMO/CA (Big Pict. These for groups are devided into two groups and each of the group belong to eMTC (enhanced machine-type communication) is a type of LTE-M network specified by 3GPP in the Release 13. g, wlan, V2X, NR etc), the list of SIB is getting longer and longer. 4 Mhz, but legacy LTE System BW with which LTE-M1 operate can be wider than 1. 4. ) Researchers propose designing future cellular networks with “island‑ready” resilient capabilities, enabling local connectivity even when central infrastructure is disrupted. 4G/LTE - Basic Procedures Physical Channel Processing This is the process that convert the bit stream coming out of channel encoding process into radio frame 4G/LTE - LTE Advanced PUCCH When you are thinking of LTE Advanced, the first feature you would think would be `Carrier Aggregation`. So I strongly recommend you to read through the legacy LTE Paging first. Even though they use a little bit 4G/LTE - Frame Numbers Subframe Number, SFN and HFN In any communication, one of the most important requirement would be that the transmitter and reiver 4G/LTE - BL/CE Narrowband LTE-M1 System Bandwidth is always 1. Paging Parameters in SIB2 +-sib2 ::= 4G/LTE - BL/CE MAX Throughput Just in terms of theoretical throughput, M1 Downlink Max throughput is same as DL Category 0 which is 1 Mbps, but considering the repetivity scheduling, MPDCCH and 4G/LTE - Basic Procedures Multi Cell / InterRAT Everybody who has experience with dealing with field trouble would know that this is never ending story, 4G/LTE - BL/CE HARQ In short, HARQ mechanism for LTE M1 downlink is similar to legacy LTE mechanism (except the repetitive transmission), but HARQ 4G/LTE - BL/CE CE Level CE Operation is categorized into four difference levels. You can think of DRX as a kind of 4G/LTE LTE Dictionary [A-C] Access Confrol (ac-Barring, SSAC, EAB, Cell Barring) Ack/Nack Repetition A-GPS AKA (Authentication and Key Agreement) ANR (Automatic Neighour Relation) APN (Access 4G/LTE - Basic Procedures Overal LTE Sequence Most of us would be specialized in one or a few specific area/layer as an engineer. For the high level description of NB-LTE and some comparative view of other technology, refer to LTE-M/Category M/M1/M2 page. See how these general criteria turns into A GSMA report forecasts 6G will reach five billion connections by 2040, but the transition will be gradual with 4G and 5G remaining central for years, and regional disparities in rollout expected. Technically it is understandable because not a single person can master everything, but I strongly recommend you to Following table ( Reference 2 ) would show you some of key technical charateristics of each LTE based MTC devices in comparison to normal LTE device (Cat 4). Early July LTE RACH in Details RACH stands for Random Access Channel. 4G/LTE - RRC SIB (System Information Block) As the functionalities of LTE evolves and start interplay with other radio technologies (e. This is the first message from UE to eNB when you power it on. IEEE Spectrum reviews Now (as of Rel 13) we can see the real implementation of these criteria because LTE MTC specification is released. In the following figure as an example, UE send 4G/LTE - NB IoT NB-IoT NB-LTE stands for Narrow Band LTE. Technically it is understandable because not a single person can As described above, in TDD LTE ibe subframe can transmit ACK/NACK for multiple subframe as shown below. eMTC is a low-power wide-area 4G/LTE - LTE Advanced Transmission Mode For the basic understanding on Transmission Mode, please refer to my previous post on Transmission Mode . 4G/LTE - LTE Advanced Quick Reference LTE Advanced : Carrier Aggregation LTE Advanced : eICIC LTE Advanced : CoMP LTE Advanced : 256 QAM LTE_Advanced : 64QAM LTE Advanced : LTE-NB : Physical Layer : Downlink : NPSS (Narrowband Primary Synchronization Signal) LTE-NB : Physical Layer : Downlink : NSSS (Narrowband Secondary Synchronization Signal) When you read the specifications of LTE M1 (BL/CE) or any other technical documents, you often see the cases where CEmode is used with CE Level and 4G/LTE LTE Dictionary [T-Z] TDD LTE : Overview TDD LTE : Frame Stracture TDD LTE : Switching Points TDD LTE : PRACH Preamble Format TDD LTE : PRACH Configuration TDD LTE : Special Most of us would be specialized in one or a few specific area/layer as an engineer.
