METHOD AND DEVICE FOR BEAM TRAINING USING BEAMFORMING CODEBOOK - A simplified explanation of the abstract
This abstract first appeared for US patent application 17515218 titled 'METHOD AND DEVICE FOR BEAM TRAINING USING BEAMFORMING CODEBOOK
Simplified Explanation
The abstract describes a communication system that supports higher data transmission rates than 4G systems. The system uses beamforming codebooks to adjust the transmission beams based on the channel state of the user equipment (UE). Here are the key points:
- The system is designed for 5G or pre-5G communication systems.
- It supports higher data transmission rates compared to 4G systems like LTE.
- The base station uses beamforming codebooks to adjust the transmission beams.
- The codebooks include different beamwidths to cover various beam angles.
- When a beam adjustment request is received from a UE, the system determines the codebook that includes beam codebooks for beam coverages matching the UE's channel state.
- The system then transmits signals to the UE using digital beamforming matrixes from the selected codebook.
Potential applications of this technology:
- Improved data transmission rates in 5G or pre-5G communication systems.
- Enhanced network capacity and coverage.
- Better performance in high-density areas with multiple UEs.
Problems solved by this technology:
- Overcoming the limitations of 4G systems in terms of data transmission rates.
- Optimizing beamforming for different channel states of UEs.
- Improving the overall efficiency and reliability of communication systems.
Benefits of this technology:
- Higher data transmission rates enable faster and more reliable communication.
- Beamforming codebooks allow for efficient adjustment of transmission beams.
- Improved network capacity and coverage result in better user experience.
- Enhanced performance in high-density areas leads to reduced congestion and improved connectivity.
Original Abstract Submitted
The disclosure relates to a 5G or pre-5G communication system for supporting higher data transmission rates than 4G communication systems such as LTE systems. According to an embodiment, a method performed by a base station supporting beam training using a beamforming codebook may comprise storing a plurality of codebooks corresponding to a plurality of different beamwidths, receiving a beam adjustment request from a user equipment (UE), determining, among the plurality of codebook, a codebook including beam codebooks for beam coverages including a beamwidth corresponding to a channel state of the UE, in response to receiving the beam adjustment request, and transmitting, to the UE, signals that are beamformed based on the codebook through a plurality of transmission beams using digital beamforming matrixes of the codebook.
