INDICATION OF SLOT OFFSET FOR A SOUNDING REFERENCE SIGNAL VIA TRIGGER VALUE - A simplified explanation of the abstract

This abstract first appeared for US patent application 18006325 titled 'INDICATION OF SLOT OFFSET FOR A SOUNDING REFERENCE SIGNAL VIA TRIGGER VALUE

Simplified Explanation

The abstract of this patent application describes a method for triggering the transmission of an aperiodic sounding reference signal (SRS) from a base station (BS) to a user equipment (UE) in a wireless communication system. The UE determines a slot offset for the SRS based on a downlink control information (DCI) communication received from the BS. The UE then transmits the SRS on the specified slot offset.

  • The patent application describes a method for triggering the transmission of an aperiodic sounding reference signal (SRS) in a wireless communication system.
  • The base station (BS) transmits a downlink control information (DCI) communication to the user equipment (UE) to configure the triggering of the SRS transmission.
  • The UE determines a slot offset for the SRS based on the DCI communication received from the BS.
  • The slot offset is determined at least in part based on a DCI codepoint, which represents the AP SRS resource trigger value.
  • The UE then transmits the aperiodic (AP) SRS on the specified slot offset.

Potential Applications:

  • This technology can be applied in various wireless communication systems, such as cellular networks, to improve the efficiency and reliability of communication between base stations and user equipment.
  • It can be used in 5G and future generations of wireless networks to enhance the performance of aperiodic sounding reference signals.

Problems Solved:

  • The method solves the problem of efficiently triggering the transmission of aperiodic sounding reference signals from base stations to user equipment.
  • It addresses the challenge of determining the appropriate slot offset for the SRS based on the received downlink control information.

Benefits:

  • Improved communication efficiency between base stations and user equipment by accurately triggering the transmission of aperiodic sounding reference signals.
  • Enhanced performance of aperiodic sounding reference signals, leading to better channel estimation and overall system performance in wireless communication systems.
  • Enables better resource allocation and management in wireless networks by optimizing the transmission of aperiodic sounding reference signals.


Original Abstract Submitted

In an aspect, a base station (BS) transmits, to a user equipment (UE), a downlink control information (DCI) communication that is configured to trigger transmission of an aperiodic (AP) sounding reference signal (SRS). The UE determines a slot offset from the DCI communication to an SRS resource set for the AP SRS based at least in part on an DCI codepoint (i.e., AP SRS resource trigger value) of the DCI communication. The UE transmits the AP SRS on the SRS resource set in accordance with the determined slot offset.
