In this chapter we shall see the deployment options of a 5G network. On a high level the architecture has been divided into 2 types. 1. NSA – Non Stand Alone Architecture 2. Standalone Architecture. EPC played an important role in 4g. Similarly, in 5G 5G …
1. eNB and gNB. 1. eNB is the LTE access network. 2. eNB should atleast need to be 3GPP Release 15 or above to connect to a 5G network 3. eNB supports legacy e-utran interfaces like S1, X2 and does not support new interfaces like NG, …
Problem Statement: You are given an m*n matrix, each cell has an integer. You need to return the path with maximum sum. You can start at any cell and you may go L, R, up or down, but you cannot visit same cell twice. Example …
Problem Statement: You are given a binary tree, you need to get all the duplicate subtree. You need to return the root of the sub trees. Example Output: The duplicate sub tree are: 2 / and 4 4 Here you need to return "2" and …
Problem Statement: You are given a binary tree, a node and an integer “k”. You need to return the kth ancestor of that node. Example The 2nd ancestor of node 4 is node 1. Solution We will use DFS in this approach. We will find the …
