==MULTIPLE DEMODULATION REFERENCE SIGNAL (DMRS) PORTS IN A CODE DIVISION MULTIPLEXING (CDM) GROUP - A simplified explanation of the abstract==


This abstract first appeared for US patent application 18365928 titled 'MULTIPLE DEMODULATION REFERENCE SIGNAL (DMRS) PORTS IN A CODE DIVISION MULTIPLEXING (CDM) GROUP

==Simplified Explanation==

The present application relates to devices and components that support multiple demodulation reference signal (DMRS) ports per code division multiplexing (CDM) group. The innovation involves the use of a frequency domain orthogonal cover code (FD-OCC) of length three or six, which allows for a higher number of DMRS ports for different DMRS configurations. 

* The FD-OCC of length three or six enables the support of at least six DMRS ports for DMRS configuration type 1 with a single symbol DMRS.
* The FD-OCC of length three or six enables the support of at least twelve DMRS ports for DMRS configuration type 1 with a double symbol DMRS.
* The FD-OCC of length three or six enables the support of at least nine DMRS ports for DMRS configuration type 2 with a single symbol DMRS.
* The FD-OCC of length three or six enables the support of at least eighteen DMRS ports for DMRS configuration type 2 with a double symbol DMRS.

Potential applications of this technology:

* Wireless communication systems
* 5G networks
* Mobile devices and smartphones
* Internet of Things (IoT) devices

Problems solved by this technology:

* Limited number of DMRS ports per CDM group
* Insufficient support for different DMRS configurations
* Inefficient use of frequency domain resources

Benefits of this technology:

* Increased flexibility in configuring DMRS ports
* Enhanced performance and capacity in wireless communication systems
* Improved spectral efficiency
* Better support for diverse applications and services in 5G networks.


==Original Abstract Submitted==

The present application relates to devices and components including apparatus, systems, and methods that support multiple demodulation reference signal (DMRS) ports per code division multiplexing (CDM) group. In an example, a frequency domain orthogonal cover code (FD-OCC) of length three or six is used, thereby allowing at least six DMRS ports for DMRS configuration type 1 with a single symbol DMRS, at least twelve DMRS ports for DMRS configuration type 1 with a double symbol DMRS, at least nine DMRS ports for DMRS configuration type 2 with a single symbol DMRS, and at least eighteen DMRS ports for DMRS configuration type 2 with a double symbol DMRS.
