IoT mMTC Deployement(?) ![](https://i.imgur.com/OkQPtwK.png) :::info I highlight this part, because Indonesia probably follow Singapore because of location and influence. Currently Indonesia has not discuss about the spectruum yet. ::: ### Notes on 5G MMWave - large bandwidths but the cell sizes would be small - 600.000 5G cell +- 100m radius for 5G coverage ![](https://i.imgur.com/h9k2Tcn.png) ## Small cell or macro cell ![](https://i.imgur.com/lRW4QD3.png) ![](https://i.imgur.com/V4A7WC1.png) ![](https://i.imgur.com/BUKsUTS.png) ## 5G NR - very low bands: 0.4 - 100 GHz - ultra wide bandwidth: uptp 100Mhz in <6GHz, upto 400 MHz in >6Ghz - different numerology - forward compability - new channel coding: LPDC (data channel) and Polar coding (Control) - Flexible and Modular RAN architecture - Network Slicing ![](https://i.imgur.com/lI9zFpT.png) Carrier Bandwidth Part is a contiguous set of physical resource blocks,selected from a contiguous subset of the common resource blocks for a given numerology(u) on a given carrier. ![](https://i.imgur.com/n9N3TuP.png) A UE can be configured with up to 4 BWPs in the downlink and with up to 4 BWPs in the uplink with a single downlink bandwidth part being active at a given time. ## MIMO in 5G ![](https://i.imgur.com/L1dACq3.png) ## Use case ![](https://i.imgur.com/ZWgv54b.png) 5G use case devided into 3: eMBB, mMTC, and uRLLC. | Capability | Description | 5G requirement | Usage scenario | |--------------------------------------------- |------------------------------------------------------------------------------- |---------------------- |---------------------- | | Downlink peak data rate | Minimum maximum data rate technology must support | 20 Gbit/s | eMBB | | Uplink peak data rate | | 10 Gbit/s | eMBB | | User experienced downlink data rate | Data rate in dense urban test environment 95% of time | 100 Mbit/s | eMBB | | User experienced uplink data rate | | 50 Mbit/s | eMBB | | Latency | Radio network contribution to packet travel time | 4 ms | eMBB | | | | 1 ms | URLLC | | Mobility | Maximum speed for handoff and QoS requirements | 500 km/h | eMBB/URLLC | | Connection density | Total number of devices per unit area | 106/km2 | mMTC | | Energy efficiency | Data sent/received per unit energy consumption (by device or network) | Equal to 4G | eMBB | | Area traffic capacity | Total traffic across coverage area | 10 Mbps/m2 | eMBB | | Peak downlink spectrum efficiency | Throughput per unit wireless bandwidth and per network cell | 30 bit/s/Hz | eMBB | ![](https://i.imgur.com/NXtjIx8.png) eMBB focused on High Data Rates MMTC focused on High Density since it need a lot of device deployment uRLLC focused on UltraReliability & Low Latency ### How to achieve 5G ![](https://i.imgur.com/QcXbcb6.png)
