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 18422700 titled 'UPLINK SPATIAL FILTER AND PRECODER FOR JOINT CHANNEL ESTIMATION ACROSS PHYSICAL UPLINK SHARED CHANNELS
Simplified Explanation
The abstract describes 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 a sounding reference signal resource indicator for each PUSCH of the set of PUSCHs, and the UE transmits the PUSCHs based on the same sounding reference signal resource.
- Joint channel estimation for physical uplink shared channels (PUSCHs) with bundled DMRS
- Base station transmits sounding reference signal resource indicator for each PUSCH
- UE transmits PUSCHs based on the same sounding reference signal resource
Potential Applications
This technology can be applied in wireless communication systems to improve the efficiency and reliability of uplink transmissions.
Problems Solved
- Enhanced channel estimation for uplink shared channels - Improved synchronization between base station and user equipment
Benefits
- Increased accuracy in channel estimation - Better utilization of uplink resources - Enhanced overall system performance
Potential Commercial Applications
Optimized uplink transmission technology for 5G networks
Possible Prior Art
Prior art may include existing methods for channel estimation and synchronization in wireless communication systems.
Unanswered Questions

The abstract does not provide specific details on the impact of this technology on system throughput.
Are there any limitations to the joint channel estimation process described?
The abstract does not mention any potential limitations or challenges associated with the joint channel estimation process.
Original Abstract Submitted
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 PUSCH of the set of PUSCHs 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 of the set of PUSCHs. The UE transmits the PUSCHs based on a same sounding reference single resource, the SRI for a first PUSCH of the set of PUSCHs indicating the same SRS resource.
