ACKNOWLEDGEMENT/NEGATIVE-ACKNOWLEDGEMENT FEEDBACK ENHANCEMENTS - A simplified explanation of the abstract

This abstract first appeared for US patent application 18053664 titled 'ACKNOWLEDGEMENT/NEGATIVE-ACKNOWLEDGEMENT FEEDBACK ENHANCEMENTS

Simplified Explanation

The abstract describes a patent application related to communication systems. The invention involves a first apparatus, which can be a network node or a component of it, receiving a Downlink Control Information (DCI) from a second or third apparatus. The DCI includes a scheduling grant for a first communication channel (CC) and a HARQ feedback offset index value. The first apparatus determines an offset value for the first CC based on the HARQ feedback offset index value and transmits a HARQ feedback message in a slot of a second CC. The HARQ feedback message indicates whether the data received from the second apparatus is acknowledged (ACK) or not acknowledged (NACK).

  • The invention involves a first apparatus receiving DCI from a second or third apparatus.
  • The DCI includes a scheduling grant for a first CC and a HARQ feedback offset index value.
  • The first apparatus determines an offset value for the first CC based on the HARQ feedback offset index value.
  • A HARQ feedback message is transmitted by the first apparatus in a slot of a second CC.
  • The slot for the HARQ feedback message is determined based on the offset value.
  • The HARQ feedback message indicates whether the data received from the second apparatus is ACK or NACK.

Potential Applications

  • This technology can be applied in wireless communication systems, such as cellular networks, to improve the efficiency and reliability of data transmission.
  • It can be used in various IoT (Internet of Things) applications where reliable communication is crucial.

Problems Solved

  • The invention solves the problem of efficiently transmitting HARQ feedback messages in a multi-carrier communication system.
  • It addresses the challenge of determining the appropriate slot for transmitting the feedback message based on the offset value.

Benefits

  • The invention improves the overall performance and reliability of communication systems by providing an efficient method for transmitting HARQ feedback messages.
  • It allows for better coordination and synchronization between different network nodes or components.
  • The technology can enhance the user experience by reducing latency and improving data transmission speeds.


Original Abstract Submitted

A first apparatus may be a first network node or a component thereof, and may receive DCI from a second apparatus or a third apparatus. The second apparatus may be a second network node or a component thereof. The third apparatus may be a third network node or a component thereof. The DCI may include a scheduling grant for a first CC to be communicated over a channel and a HARQ feedback offset index value. The first apparatus may determine, based on the HARQ feedback offset index value, an offset value of a first plurality of offset values associated with a first CC. The first apparatus may transmit a HARQ feedback message in a slot of a second CC. The slot may be based on the determined offset value. The HARQ feedback message may indicate one of an ACK or NACK for data received from the second apparatus.
