PORT GROUPING FOR A CHANNEL STATE INFORMATION-REFERENCE SIGNAL (CSI-RS) RESOURCE - A simplified explanation of the abstract
- This abstract for appeared for US patent application number 17922942 Titled 'PORT GROUPING FOR A CHANNEL STATE INFORMATION-REFERENCE SIGNAL (CSI-RS) RESOURCE'
Simplified Explanation
The abstract describes a method and apparatus for associating channel state information-reference signal (CSI-RS) ports with transmission configuration indicator (TCI) states. This involves mapping the CSI-RS ports to antenna elements of an antenna array and transmitting the CSI-RS to a scheduled entity. The scheduled entity then associates the CSI-RS ports with TCI states, determines pre-coding matrix indicators (PMIs), and transmits the PMIs to the scheduling entity.
Original Abstract Submitted
Aspects of the disclosure relate to methods and apparatus that involve associating a first plurality of channel state information-reference signal (CSI-RS) ports with a second plurality of transmission configuration indicator (TCI) states according to a rule at a scheduling entity, mapping the first plurality of CSI-RS ports to antenna elements of an antenna array in accordance with the rule, and transmitting CSI-RS to a scheduled entity, receiving CSI-RS at the scheduled entity and associating the first plurality of CSI-RS ports with the second plurality of transmission configuration indicator (TCI) states according to a rule at the scheduled entity, determining pre-coding matrix indicators (PMIs) corresponding to the second plurality of TCI states, and transmitting the PMIs corresponding to the second plurality of TCI states to the scheduling entity. Other aspects, embodiments, and features are also claimed and described.
