VARIABLE COHERENCE ADAPTIVE ANTENNA ARRAY - A simplified explanation of the abstract
This abstract first appeared for US patent application 18081436 titled 'VARIABLE COHERENCE ADAPTIVE ANTENNA ARRAY
Simplified Explanation
The patent application describes a method for wireless communication networks where a user equipment (UE) transmits over multiple antenna ports and receives a control message from a base station. The control message includes a precoding matrix indication field that can be configured in three different ways.
- The first configuration identifies precoding matrices in both a first set and a second set of precoding matrices.
- The second configuration identifies precoding matrices in the second set but not in the first set.
- The third configuration identifies precoding matrices in a third set in addition to the first and second sets.
These precoding matrices are used for transmissions from the UE and each set corresponds to a specific coherence capability. The first, second, and third configurations occupy 5, 4, and 6 information bits respectively, for a maximum of four spatial layers.
Potential applications of this technology:
- Wireless communication networks
- 5G and beyond networks
- Multiple antenna systems
Problems solved by this technology:
- Efficient transmission and reception of control messages in wireless communication networks
- Optimization of precoding matrices for different coherence capabilities
- Improved performance and reliability of wireless communication systems
Benefits of this technology:
- Enhanced data transmission rates and capacity in wireless networks
- Improved signal quality and reduced interference
- Increased flexibility and adaptability in configuring precoding matrices for different scenarios
Original Abstract Submitted
A user equipment (UE) transmits over multiple antenna ports and receives a control message from a base station in a wireless communication network. The control message comprises a precoding matrix indication field configurable to a first, second, and third configuration. The first configuration identifies precoding matrices in both a first set of precoding matrices and a second set of precoding matrices. The second configuration identifies precoding matrices in the second set of precoding matrices but not in the first set of precoding matrices. The third configuration identifies precoding matrices in a third set of precoding matrices in addition to the first and second sets. The precoding matrices in the sets are precoding matrices for transmissions from the UE. Each set of precoding matrices corresponds to a respective coherence capability. For a maximum of four spatial layers, the first, second, and third configurations occupy 5, 4, and 6 information bits, respectively.
