There is a finite set of time and frequency resources. These resources are dynamically allocated to the different connected devices (UE) that are accessing the 5G network, in such a manner that they will efficiently serve the network. This is known as shared channel transmission. The main function of scheduling is to decide which devices …

PHY-Layer (functions) CRCFirst we need a mechanism to detect error on the level of transport block. For this purpose CRC(Cyclic Redundancy Check) is calculated and added to the transport block. On the receiver side, CRC can be used to detect error in …

Hybrid-ARQ retransmission 3. Scheduling 4. Multiplexing/Demultiplexing for carrier aggregation Multiplexing Logical Channel MAC layer provides the services to the RLC in the form of logical channels. MAC layer uses services from PHY layer …
There are two different types of Ran Protocol Stack as follow 1) User-Plane Protocol Stack 2) Control-Plane Protocol Stack Lets us discuss with the help of diagram USER-PLANE PROTOCOL STACK It supports in carrying the user data network between different applications of user equipment and in the network. Each layers shown in above diagram provides …
