SYSTEMS AND METHODS FOR NON-CODEBOOK BASED MULTI-TRP PUSCH - A simplified explanation of the abstract
This abstract first appeared for US patent application 18552850 titled 'SYSTEMS AND METHODS FOR NON-CODEBOOK BASED MULTI-TRP PUSCH
Simplified Explanation
The patent application describes systems and methods for non-codebook based multi-Transmit and Reception Point (TRP) Physical Uplink Shared Channel (PUSCH). Here are some key points to explain the innovation:
- Wireless devices receive a configuration of Phase-Tracking Reference Signals (PT-RS) port index per Sounding Reference Signal (SRS) resource in two SRS resource sets for non-codebook based PUSCH.
- The devices receive indications of SRS Resource Indicators (SRIs) from two different SRS resource sets.
- Based on the received SRIs, the devices determine the number of PT-RS ports to be transmitted for each set of SRS resources.
- The determined PT-RS ports are then transmitted along with a plurality of PUSCH repetitions.

- Potential Applications
- This technology can be applied in 5G and beyond wireless communication systems to improve uplink transmission efficiency.
- It can be used in IoT devices, smart grids, and other applications requiring reliable and high-speed wireless connectivity.
- Problems Solved

Original Abstract Submitted
Systems and methods for non-codebook based multi-Transmit and Reception Point (TRP) Physical Uplink Shared Channel (PUSCH) are provided. In some embodiments, a method performed by a wireless device includes: receiving a configuration of a first or second Phase-Tracking Reference Signals (PT-RS) port index per Sounding Reference Signal (SRS) resource in two SRS resource sets for non-codebook based PUSCH; receiving indication of: a first set of SRS Resource Indicators (SRIs) from a first SRS resource set; and/or a second set of SRIs from a second SRS resource set; determining at least one of: a first number of PT-RS ports to be transmitted according to the SRS resources indicated in the first set of SRIs; and a second number of PT-RS ports to be transmitted according to the SRS resources indicated in the second set of SRIs; and transmitting the determined number of PT-RS ports along with a plurality of PUSCH repetitions.
