What is codebook based precoding?

Codebook-based precoding allows the system to dispense with full channel state information at the transmitter (CSIT). This considerably reduces the feedback overhead. Phase-only codebooks with systematic structure are investigated since they avoid increasing the peak to average power ratio of the transmitted signal.

What is pusch in 5G?

In 5G NR, PUSCH is the physical uplink channel that carries user data. DM-RS and PT-RS are the reference signals associated with PUSCH. DM-RS is used for channel estimation as part of coherent demodulation of PUSCH. To compensate for the common phase error (CPE), 3GPP 5G NR introduced PT-RS.

What is codebook mode 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.

What is codebook in MIMO?

Abstract: The codebook based precoding is a promising technology adopted by Long Term Evolution (LTE), which fixes a common codebook comprising a set of vectors and matrices at both the transmitter and the receiver.
