AI-5G Introduction part -2

Home                 LTE                NB-IoT            5G(NR-NSA) How does AI integrate with 5G? We all know that artificial intelligence is not only an interesting technology that improves accuracy and prediction on variety of problems but, it also   ultimately required to be used to take out the intelligence from the large amount of data produced on modern day networks. Also today’s data is not only large but it is growing so fast that about 80% of data is produced in last two years only. Special industrial tenants are provided with a complete end to end virtual network by network slicing. We know that to ensure a good quality of experience (QoE) for industrial users in a virtual network is the key to successful network slicing. Now to improve the experience of the slice users it is primarily necessary to construct a wide range data map of the slicing. Data about slice users, Qos, events, subscription and logs can be collected in real time for multi dimensional analysis

AI-5G Introduction part -1

Home                 LTE                NB-IoT            5G(NR-NSA) Symbiotic relationship of AI and 5G: In this section we will learn about the Artificial Intelligence (AI) in 5G. we all know that the recent breakthroughs in AI and computing have encouraged researchers in the field of wireless communications to study and leverage   AI especially in the 5G context. As we know 5G provides higher bandwidth networks promising super fast speed and at the same time it also provides reliability and responsiveness. On the other hand artificial intelligence (AI) is technology that can analyze massive amounts of data and learn from previous actions. So if both AI and 5G network are combined together, they have the potential to pack a significantly more powerful punch and work as wonders. Here when both (5G and AI) are combined AI can provide its intelligence to decode 5G’s complexity whereas the 5G network will provide a mechanism that can help in transmitting the large amou

BWP Part-1

Home                 LTE                NB-IoT            5G(NR-NSA) To learn more about 5G, please click here . BWP Basic  Before we learn more about BWP first of all we learn what was the need to introduce BWP in NR: BWP is a new concept introduced in 5G mainly to reduce the power consumption of the mobile phone as the 5G bandwidth is large upto 400MHz. Different numerology support different bandwidth size. Thus we can say that bandwidth part is a subset of the entire bandwidth. The frequency of 5G are divided into two parts as per the range as defined in   38.101: 1) FR1(Frequency Range 1): f < 6GHz(low frequency) 15kHz SCS:   Support 5,10,15,20,25,30,40,50 MHz bandwidth (Maximum PRB 270) 30kHz SCS: Support 5,10,15,20,25,30,40,50,60,70,80,90,100 MHz bandwidth (Maximum PRB 273) 60kHz SCS: Support 5,10,15,20,25,30,40,50,60,70,80,90,100 MHz bandwidth (Maximum PRB 135) 2) FR2 (Frequency Range 2):   f > 6GHz(High frequency or

Carrier Aggregation & Dual Connectivity

Home                 LTE                NB-IoT            5G(NR-NSA) What is CA? Carrier Aggregation is a technology through which, a UE can use multiple component carriers to transmit/receive data to/from the eNodeB. It was introduced in 3GPP Release 10. Release 8 and 9 UEs supported only one component carrier. Release 10 UEs can support up to 5 Component Carriers – 1 Primary Carrier, up to 4 Secondary Carriers. The main component carrier is called Primary Component Carrier (PCC) and others are called Secondary Component Carriers (SCC) . Thus the maximum bandwidth that can be allocated to a UE is 100 MHz (20+20+20+20+20). The number of uplink carriers can never be more than the number of downlink carriers, but the reverse is possible and usually the case. It is supported in both FDD and TDD. What was the motivation behind introducing CA? The primary objective of introducing CA was to increase the bandwidth and thus provide high data rates to the
