TECHNIQUES FOR IMPLICIT PATHLOSS REFERENCE SIGNALING IN TRANSMISSION CONFIGURATION INDICATORS - A simplified explanation of the abstract

This abstract first appeared for US patent application 18273471 titled 'TECHNIQUES FOR IMPLICIT PATHLOSS REFERENCE SIGNALING IN TRANSMISSION CONFIGURATION INDICATORS

Simplified Explanation

The abstract describes a method for wireless communication using an implicit pathloss reference signal (PLRS) in a transmission configuration indication (TCI) to determine uplink power control information.

• Receiving TCI state configuration from a base station
• Determining PLRS is not explicitly indicated by the TCI state configuration
• Obtaining default PLRS in response to the lack of explicit indication
• Transmitting UL power control information based on the default PLRS in a UL transmission

Potential Applications

This technology can be applied in various wireless communication systems where efficient power control is essential, such as 5G networks, IoT devices, and satellite communications.

Problems Solved

1. Efficient power control: By using the default PLRS when not explicitly indicated, the method ensures accurate power control information transmission. 2. Simplified communication: The use of implicit PLRS in TCI reduces the need for additional signaling, streamlining the communication process.

Benefits

1. Improved reliability: By utilizing implicit PLRS, the method enhances the reliability of power control information transmission. 2. Enhanced efficiency: The approach simplifies the communication process and optimizes power control, leading to improved overall system efficiency.

Potential Commercial Applications

Possible Prior Art

One possible prior art could be the use of explicit pathloss reference signals in power control mechanisms in wireless communication systems. However, the specific technique of using implicit PLRS in TCI as described in this patent application may be a novel approach.

How does this method handle interference in the wireless communication environment?

The method described in the abstract focuses on power control based on the default PLRS. It would be interesting to know if and how the system adapts to interference scenarios to maintain reliable communication.

What impact does the use of implicit PLRS have on overall system latency?

While the abstract highlights the benefits of using implicit PLRS in TCI, it does not address the potential impact on system latency. Understanding how this method affects latency could provide valuable insights into its practical implementation.

Original Abstract Submitted

Techniques for using implicit pathloss reference signal (RS) in a transmission configuration indication (TCI) may be performed. In an example, a method of wireless communication by a user equipment (UE), may include receiving, from a base station, a TCI state configuration. The method may also include determining a PLRS is not explicitly indicated by the TCI state configuration. The method may also include obtaining a default PLRS in response to the PLRS not being explicitly indicated by the TCI state configuration. The method may also include transmitting, to the base station, uplink (UL) power control information based on the default PLRS in a UL transmission.
