SIGNALING OF SOUNDING REFERENCE SIGNAL GROUPING - A simplified explanation of the abstract

This abstract first appeared for US patent application 18264743 titled 'SIGNALING OF SOUNDING REFERENCE SIGNAL GROUPING

Simplified Explanation

The abstract describes methods, systems, and devices for wireless communications involving group-based sounding reference signal transmission using multiple antenna groups at a user equipment (UE).

• User equipment (UE) can identify multiple antenna groups, each with two or more antenna ports, for group-based sounding reference signal transmission.
• The UE receives an indication of a sounding reference signal configuration specifying resources for group-based sounding reference signal transmissions using at least one of the antenna groups.
• The UE transmits sounding reference signals using the specified resources and at least one antenna port from the identified antenna groups.

Potential Applications

This technology can be applied in:

• 5G and future wireless communication systems
• Massive MIMO (Multiple Input Multiple Output) systems

Problems Solved

• Efficient utilization of multiple antenna resources

Original Abstract Submitted

Methods, systems, and devices for wireless communications are described. A user equipment (UE) may identify one or more antenna groups at the UE, each of the one or more antenna groups comprising two or more antenna ports and associated with group-based sounding reference signal transmission. The UE may receive an indication of a sounding reference signal configuration identifying one or more resources for performing group-based sounding reference signal transmissions using at least one of the one or more antenna groups. The UE may transmit one or more sounding reference signals using the one or more resources and at least one antenna port from the at least one of the one or more antenna groups.
