==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 ==
=== How does this technology impact the overall throughput of the system? ===
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.
