5g transmission modes

According to the definition of 3GPP, 5G has two networking modes: SA (Standalone) and NSA (Non-Standalone).

What are transmission modes in LTE?

The LTE standard supports 1, 2, 4 or 8 base station transmit antennas and 2, 4 or 8 receive antennas in the User Equipment (UE), designated as: 1x2, 1x4, 1x8, 2x2, 2x4, 2x8, 4x2, 4x4, 4x8, and 8x2, 8x4, and 8x8 MIMO, where the first digit is the number of antennas per sector in the transmitter and the second number is ...

How does 5G MIMO work?

Massive MIMO contributes to increased capacity first by enabling 5G NR deployment in the higher frequency range in Sub-6 GHz (e.g., 3.5 GHz); and second by employing MU-MIMO where multiple users are served with the same time and frequency resources.

What is SSB beamforming?

Beamforming concept. In the 5G New Radio (NR) initial access procedure, multiple synchronization signal blocks (SSBs) are sent in a burst set period, each SSB potentially in a different beam.

What is codebook in 5G?

Codebook based precoding is a promising new technique of beamforming. Precoding means multiple data streams or a single data stream are transmitted from the transmit antennas with independent and appropriate weightings that will lead to maximize the throughput at the receiver side.
