The United States Patent and Trademark Office (USPTO) has issued patent US12587335B2, titled "Systems and methods for indicating demodulation reference signal ports for wireless communication," to ZTE CORPORATION. This patent covers novel systems and methods for wireless communication devices to determine demodulation reference signal (DMRS) parameters based on information received from a wireless communication node. The abstract specifies that the device determines a DMRS table and then a DMRS parameter using a field value from the node's signaling, where the table maps field values to parameter values.

This patent grant represents a new intellectual property right for ZTE CORPORATION in the field of wireless communications technology. While it does not impose direct compliance obligations on other entities, it signifies a specific technological advancement that may influence future industry standards, product development, and potential licensing agreements. Companies operating in the wireless communication sector, particularly those involved in device manufacturing or network infrastructure, should be aware of this patent as it pertains to DMRS signaling and parameter determination.
