PUSCH DMRS BUNDLING INDICATION FOR PUSCH REPETITIONS - A simplified explanation of the abstract
This abstract first appeared for US patent application 18253179 titled 'PUSCH DMRS BUNDLING INDICATION FOR PUSCH REPETITIONS
Simplified Explanation
The patent application describes a method for a User Equipment (UE) to perform DMRS (Demodulation Reference Signal) bundling in uplink data channel transmissions in response to a configuration from a base station. DMRS bundling is used for joint channel estimation, which improves link quality and signal gains.
- The UE receives a configuration from the base station indicating to bundle DMRS in repetitions of an uplink data channel transmission.
- Based on the configuration, the UE determines a DMRS bundling window.
- The UE transmits the bundled DMRS within the DMRS bundling window.
- The base station performs joint channel estimation using the bundled DMRS.
- Applying DMRS bundling over multiple repetitions of PUSCH (Physical Uplink Shared Channel) transmissions can result in improved link quality and signal gains.
Potential Applications
- Wireless communication systems
- 5G networks
- Mobile devices
Problems Solved
- Inaccurate channel estimation in wireless communication systems
- Poor link quality and signal gains in uplink data channel transmissions
Benefits
- Improved link quality between the UE and base station
- Increased signal gains
- Enhanced performance of wireless communication systems
Original Abstract Submitted
Aspects are provided that allow a UE to perform DMRS bundling in PUSCH repetitions in response to a configuration from a base station indicating or enabling the UE to perform the DMRS bundling. The UE receives a configuration from a base station indicating to bundle DMRS in repetitions of an uplink data channel transmission for joint channel estimation. The UE determines a DMRS bundling window based on the configuration. The UE transmits the bundled DMRS in the DMRS bundling window. The base station performs the joint channel estimation based on the bundled DMRS. Improved link quality between the UE and base station and signal gains may accordingly result from applying DMRS bundling over multiple repetitions of PUSCH transmissions.
