SYSTEMS AND METHODS FOR ENHANCEMENT ON SIDELINK POWER CONTROL - A simplified explanation of the abstract

This abstract first appeared for US patent application 18531176 titled 'SYSTEMS AND METHODS FOR ENHANCEMENT ON SIDELINK POWER CONTROL

Simplified Explanation

The patent application describes systems and methods for sidelink power control in wireless communication systems. Here are the key points:

• User equipment (UE) selects a parameter set to calculate transmit power for channels in an SL session with a peer UE based on distance.
• The UE determines whether to use an SL pathloss-based calculation for transmit power based on distance.
• UE selects the number of physical SL feedback channel (PSFCH) transmissions to match its capability.
• Determinations are made regarding whether to perform PSFCH reception or transmission.

Potential Applications

This technology can be applied in various wireless communication systems where sidelink power control is necessary, such as in vehicle-to-vehicle communication, device-to-device communication, and Internet of Things (IoT) networks.

Problems Solved

1. Efficient power control in sidelink communication to optimize transmission quality and coverage. 2. Adaptation of power control based on distance between devices for better performance.

Benefits

1. Improved reliability and performance of sidelink communication. 2. Enhanced network efficiency and resource utilization. 3. Better user experience with optimized power control mechanisms.

Potential Commercial Applications

The technology can be utilized in industries such as automotive (for vehicle communication systems), smart cities (for IoT networks), and telecommunications (for device-to-device communication).

Possible Prior Art

One possible prior art could be existing power control mechanisms in wireless communication systems that may not specifically address sidelink communication and distance-based power control.

How does this technology impact battery life in user equipment during sidelink communication sessions?

The patent application does not provide information on the potential impact of this technology on the battery life of user equipment. This could be an important consideration for practical implementation and user experience.

Are there any potential interoperability issues with existing wireless communication standards when implementing this technology?

The patent application does not address any potential interoperability challenges that may arise when integrating this technology with existing wireless communication standards. Ensuring seamless compatibility with different systems could be crucial for widespread adoption and deployment.

Original Abstract Submitted

Systems and methods for sidelink (SL) power control within wireless communication systems are disclosed herein. A user equipment (UE) selects a parameter set to use to calculate a transmit power of one or more channels to be transmitted according to an SL session with a peer UE from a plurality of parameter sets each configured for use according to a distance between the UE and the peer UE. A UE determines whether an SL pathloss based calculation is to be used to calculate a transmit power of a channel according to an SL session with a peer UE, wherein that calculation is configured to be used depending on a distance between the UE and the peer UE. UE selection of a number of physical SL feedback channel (PSFCH) transmissions to match a UE capability and determinations regarding whether to perform PSFCH reception or PSFCH transmission are also discussed.
