PRECODERS FOR MULTI-PANEL UPLINK TRANSMISSION - A simplified explanation of the abstract
This abstract first appeared for US patent application 18149610 titled 'PRECODERS FOR MULTI-PANEL UPLINK TRANSMISSION
Simplified Explanation
The patent application describes techniques for precoding in multi-panel uplink transmission.
- The user equipment (UE) determines preferred precoders for uplink transmission using an expanded UE codebook.
- The UE sends an indication or transmits using the determined precoders to the base station (BS).
- For non-codebook based transmission, the UE computes precoders based on reference signals received from different ports of the BS.
Potential Applications
- Wireless communication systems
- Cellular networks
- Uplink transmission in multi-panel UE devices
Problems Solved
- Efficient precoding for uplink transmission in multi-panel UE devices
- Improved communication performance in wireless networks
Benefits
- Enhanced signal quality and reliability in uplink transmission
- Increased capacity and throughput in wireless networks
- Improved user experience in cellular communication systems
Original Abstract Submitted
Certain aspects of the present disclosure provide techniques for precoding for multi-panel uplink transmission. For codebook-based uplink transmission, a user equipment (UE) can determine one or more preferred or selected precoders for uplink transmission. The precoders can be from an expanded UE codebook that maps a first number of transmit layers at the UE to a second number of antenna ports at the UE, the layers and/or antenna ports associated with multiple uplink transmit panels at the UE. The UE sends an indication to a base station (BS) of the determined precoders and/or sends an uplink transmission using the determined precoders. For non-codebook based uplink transmission the UE receives first and second reference signals (RSs), from first and second ports of a BS, with first and second UE antenna panels. The UE computes precoders to use for uplink transmission based on the RSs.
