mcg and scg in 5g

Last updated on 

There are several key concepts and components that are commonly discussed. Some of these include:

  1. User Equipment (UE): This refers to the end-user device, such as a smartphone or other wireless device.
  2. NodeB (gNB): In 5G, the base station is referred to as gNB (next-generation NodeB). It's responsible for communication with UEs over the air interface.
  3. Core Network (CN): The core network handles various functions such as mobility management, session management, and connection to external networks.
  4. Radio Access Network (RAN): The RAN includes the gNBs and the connection to the core network. It is responsible for radio communication with UEs.
  5. Millimeter Wave (mmWave): 5G networks use higher-frequency bands, including mmWave, to achieve higher data rates.
  6. Massive MIMO: Multiple Input, Multiple Output (MIMO) technology is used in 5G to improve spectral efficiency. Massive MIMO involves a large number of antennas to serve multiple users simultaneously.
