Application: Method and system for signaling transmission layers for single user and multi user mimo (Patent ID: US20240107552A1)
The patent filed by BlackBerry Ltd. describes a method and system for signaling transmission layers or dedicated reference signal ports in a multiple input multiple output (MIMO) system. The method involves providing a downlink control signal containing information for the transmission layers or dedicated reference signal ports used, which are then utilized to demodulate data on each transmission layer. The claims detail the specific steps and components involved in the method, including transmitting information to User Equipment (UE), using layer combinations or associated combinations of dedicated reference signal ports, supporting multiple-user MIMO transmissions, and associating scrambling codes with the field. The patent also covers network elements such as eNodeBs capable of LTE and LTE-advanced operations, as well as non-transitory computer-readable mediums storing instructions for executing the method and UEs with processors and communications subsystems.
In summary, the patent from BlackBerry Ltd. focuses on a method and system for optimizing signal transmission in a MIMO system by providing specific information to UEs, utilizing dedicated reference signal ports, and supporting multiple-user MIMO transmissions. The patent covers various aspects of the method, including the use of scrambling codes, network elements like eNodeBs, and UEs operating during LTE and LTE-advanced operations. The claims outline the specific steps, components, and functionalities involved in implementing the method, emphasizing the efficiency and effectiveness of the proposed system.
