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

This abstract first appeared for US patent application 20240121757 titled 'SYSTEMS AND METHODS FOR ENHANCEMENT ON SIDELINK POWER CONTROL

Simplified Explanation

The patent application describes systems and methods for sidelink (SL) power control within wireless communication systems. Here are the key points explained in bullet 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 the distance to the peer UE.
• UE selects the number of Physical SL Feedback Channel (PSFCH) transmissions based on UE capability.
• Determinations are made on whether to perform PSFCH reception or transmission.

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.
