UPLINK SPATIAL FILTER AND PRECODER FOR JOINT CHANNEL ESTIMATION ACROSS PHYSICAL UPLINK SHARED CHANNELS - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240162951 titled 'UPLINK SPATIAL FILTER AND PRECODER FOR JOINT CHANNEL ESTIMATION ACROSS PHYSICAL UPLINK SHARED CHANNELS
Simplified Explanation
The abstract describes a patent application for a system where a base station performs joint channel estimation for a set of physical uplink shared channels (PUSCHs) with bundled DMRS from a user equipment (UE). The UE receives an indication to transmit the set of PUSCHs, each comprising a corresponding DMRS from the base station. The base station transmits, and the UE receives, a sounding reference signal resource indicator for each PUSCH. The UE transmits the PUSCHs based on the same sounding reference signal resource, with the SRI for the first PUSCH indicating the same SRS resource.
- Base station performs joint channel estimation for a set of PUSCHs with bundled DMRS from a UE.
- UE receives indication to transmit PUSCHs, each with corresponding DMRS from base station.
- Base station transmits SRI for each PUSCH.
- UE transmits PUSCHs based on the same SRS resource.
Potential Applications
This technology can be applied in wireless communication systems, specifically in improving the efficiency and reliability of uplink transmissions in cellular networks.
Problems Solved
1. Enhanced channel estimation accuracy for uplink transmissions. 2. Simplified resource allocation for multiple PUSCHs from a UE.
Benefits
1. Improved signal quality and reliability. 2. Increased spectral efficiency. 3. Enhanced overall performance of uplink communications.
Potential Commercial Applications
Optimized resource allocation and improved uplink transmission efficiency can benefit telecommunications companies, network equipment manufacturers, and providers of wireless communication services.
Possible Prior Art
One possible prior art could be the use of dedicated reference signals for channel estimation in wireless communication systems.
What are the specific technical details of the joint channel estimation process described in the patent application?
The specific technical details of the joint channel estimation process in the patent application involve the base station transmitting a sounding reference signal resource indicator for each PUSCH, allowing the UE to transmit the PUSCHs based on the same sounding reference signal resource. This enables the UE to synchronize its transmissions with the base station and improve the accuracy of channel estimation for the set of PUSCHs.
How does this innovation compare to existing methods of channel estimation in wireless communication systems?
This innovation improves upon existing methods of channel estimation by providing a more efficient and reliable way to estimate the channel characteristics for a set of PUSCHs with bundled DMRS. By using a joint channel estimation approach and a common sounding reference signal resource, the system simplifies resource allocation and enhances the overall performance of uplink transmissions in wireless communication systems.
