1Productivity
If reference signals are transmitted to support multiple antennas for massive MIMO, then data transmission rates and coverage are enhanced, but system complexity and overhead increase
Solution Approach 1:
The patent segments the reference signal transmission by dividing the antenna array into multiple antenna groups, where each group is configured independently with separate reference signals. This allows the system to support massive MIMO with many antennas while managing complexity through modular organization of antenna configurations and reference signal resources.
Solution Approach 2:
The patent introduces antenna group indexing as an additional dimension to organize the massive antenna array. By adding the group index dimension alongside the antenna port dimension, the system can efficiently manage and identify individual antennas within large-scale MIMO configurations without linearly increasing overall system complexity.
2Area of stationary object
If antenna configuration information is provided for multiple antennas, then coverage and transmission performance improve, but signaling overhead increases
Solution Approach 1:
The patent creates a universal antenna group configuration framework where a single antenna group index can represent multiple antenna ports within that group. This multi-functional indexing approach allows the same signaling structure to cover various antenna configurations and scenarios, reducing the need for separate signaling for each individual antenna while maintaining comprehensive coverage support.

AI summary
A method for transmitting a reference signal for supporting a plurality of antennas to a User Equipment (UE) at a Base Station (BS) in a wireless communication system is disclosed. The method includes grouping the plurality of antennas into antenna groups comprising a predetermined number of antenna ports, transmitting resource information about a reference signal for at least one antenna group of the antenna groups, and transmitting the reference signal for the at least one antenna group to the UE based on the resource information.
