METHOD AND APPARATUS FOR CODEBOOK BASED UL TRANSMISSION - A simplified explanation of the abstract

This abstract first appeared for US patent application 17930583 titled 'METHOD AND APPARATUS FOR CODEBOOK BASED UL TRANSMISSION

Simplified Explanation

The patent application describes methods and apparatuses for codebook based UL (uplink) transmission. It introduces a method for operating a UE (user equipment) that involves transmitting UE capability information about a UL codebook for 8 antenna ports, receiving an indication indicating a TPMI (transmit precoding matrix indicator) for a transmission of a PUSCH (physical uplink shared channel), and transmitting the PUSCH based on the indicated TPMI. The TPMI indicates a precoding matrix from the UL codebook for the 8 antenna ports, where the UL codebook includes full-coherent (FC) precoding matrices comprising all non-zero entries, and each column of a FC precoding matrix is associated with a layer of the PUSCH transmission.

  • The patent application introduces a method for UL transmission using a codebook and precoding matrices.
  • The UE transmits its capability information about a UL codebook for 8 antenna ports.
  • The UE receives an indication of a TPMI for a PUSCH transmission.
  • The PUSCH is transmitted based on the indicated TPMI, which corresponds to a precoding matrix from the UL codebook.
  • The UL codebook includes full-coherent (FC) precoding matrices with all non-zero entries.
  • Each column of a FC precoding matrix is associated with a layer of the PUSCH transmission.

Potential Applications

  • This technology can be applied in wireless communication systems that utilize codebook based UL transmission.
  • It can be used in 5G networks and future generations of wireless networks to enhance uplink data transmission.

Problems Solved

  • The patent application addresses the problem of efficient UL transmission in wireless communication systems.
  • It solves the challenge of selecting an appropriate precoding matrix for uplink transmission based on the UE's capability and the channel conditions.

Benefits

  • The use of a codebook and precoding matrices allows for efficient and optimized UL transmission.
  • The method provides flexibility in selecting the precoding matrix based on the indicated TPMI, improving the overall performance of the uplink transmission.
  • By associating each column of a FC precoding matrix with a layer of the PUSCH transmission, the method enables effective utilization of multiple antenna ports for improved data transmission.


Original Abstract Submitted

Methods and apparatuses for codebook based UL transmission are provided. A method for operating a UE comprises transmitting a UE capability information about a UL codebook for 8 antenna ports; receiving an indication indicating a TPMI for a transmission of a PUSCH; and transmitting the PUSCH based on the indicated TPMI, wherein the TPMI indicates a precoding matrix from the UL codebook for the 8 antenna ports, the UL codebook includes full-coherent (FC) precoding matrices comprising all non-zero entries, and an l-th column of a FC precoding matrix is associated with an l-th layer of the PUSCH transmission.
