UPLINK SUBBAND PRECODING VIA LINEAR COMBINATION OF FREQUENCY DOMAIN BASES - A simplified explanation of the abstract
This abstract first appeared for US patent application 17767378 titled 'UPLINK SUBBAND PRECODING VIA LINEAR COMBINATION OF FREQUENCY DOMAIN BASES
Simplified Explanation
The patent application describes a technique for using subband precoding for uplink transmissions in a wireless network.
- The technique involves a user equipment (UE) transmitting sounding reference signals (SRS) to a network entity.
- The UE receives information indicating a set of frequency domain (FD) bases and linear combination coefficients, determined based on the SRS transmission.
- Based on the linear combination coefficients, the UE determines subband precoding by linearly combining the FD bases.
- The UE then transmits a physical uplink shared channel (PUSCH) using the subband precoding.
Potential Applications
- This technique can be applied in wireless communication systems to improve the efficiency and reliability of uplink transmissions.
- It can be used in various wireless network environments, such as cellular networks, Wi-Fi networks, and IoT networks.
Problems Solved
- Traditional uplink transmission techniques may suffer from interference and limited capacity.
- This technique solves the problem of interference by using subband precoding, which improves the signal quality and reduces interference.
- It also solves the problem of limited capacity by optimizing the use of frequency resources through linear combinations of FD bases.
Benefits
- Improved signal quality and reduced interference in uplink transmissions.
- Increased capacity and efficiency in wireless networks.
- Enhanced reliability and performance of communication systems.
Original Abstract Submitted
Certain aspects of the present disclosure provide techniques for using subband precoding for uplink transmissions. In some cases, a UE may transmit sounding reference signals (SRS) to a network entity, receive information indicating at least one of a set of one or more frequency domain (FD) bases and linear combination coefficients, determined based on the SRS transmission, determine subband precoding based at least in part on linear combinations of the FD bases based on the linear combination coefficients, and transmit a physical uplink shared channel (PUSCH) with the subband precoding.
