==DEMODULATION REFERENCE SIGNAL (DMRS) MODIFICATIONS FOR MULTIPLE SIGNALING, MULTIPLE TRANSMISSION RECEPTION POINT (TRP) OPERATION - A simplified explanation of the abstract==


This abstract first appeared for US patent application 18056036 titled 'DEMODULATION REFERENCE SIGNAL (DMRS) MODIFICATIONS FOR MULTIPLE SIGNALING, MULTIPLE TRANSMISSION RECEPTION POINT (TRP) OPERATION

==Simplified Explanation==

This patent application describes a method for avoiding collisions between demodulation reference signals (DMRS) and cell specific reference signals (CRS) in wireless communication systems. 

* The conventional networks and devices may not be able to shift DMRS in certain modes, which can lead to interference or decoding failure.
* The disclosed method enables DMRS shifting in multiple transmission resource pattern (TRP) modes.
* The DMRS symbols of both transmissions can be shifted to align their locations and enable successful decoding.
* This method improves the overall performance and reliability of wireless communication systems.

==Potential Applications==
* Wireless communication systems
* Cellular networks
* Internet of Things (IoT) devices
* 5G and future generations of wireless networks

==Problems Solved==
* Avoiding collisions between DMRS and CRS patterns
* Ensuring alignment of DMRS symbols in multiple TRP modes
* Preventing interference and decoding failure in wireless communication systems

==Benefits==
* Improved performance and reliability of wireless communication systems
* Enhanced decoding of transmissions
* Reduction in interference and decoding failure
* Better utilization of available resources in wireless networks


==Original Abstract Submitted==

This disclosure provides systems, methods, and apparatus, including computer programs encoded on computer storage media, for demodulation reference signal (DMRS) and cell specific reference signal (CRS) collision avoidance procedures for wireless communication. Conventional networks and devices may be unable to perform DMRS shifting in some modes. For example, when considering two transmissions of multiple TRP modes, if a DMRS symbol for one transmission is shifted due to a collision with a CRS pattern, the alignment of the transmissions may be altered. If DMRS symbols of the transmissions are not aligned, interference or decoding failure may occur. The disclosure enables procedures for performing DMRS shifting in multiple TRP modes. For example, the DMRS symbols of both transmissions may be shifted responsive to determining an overlap for one transmission. Such shifting may enable the alignment of the DMRS locations for both transmissions to enable decoding of the transmissions.
