TECHNIQUES FOR SIDELINK FEEDBACK CHANNEL RESOURCE DETERMINATION - A simplified explanation of the abstract

This abstract first appeared for US patent application 17479680 titled 'TECHNIQUES FOR SIDELINK FEEDBACK CHANNEL RESOURCE DETERMINATION

Simplified Explanation

The patent application describes methods, systems, and devices for wireless communications, specifically focusing on communicating sidelink feedback for a transport block over multiple transmission time intervals (TTIs). Here is a simplified explanation of the abstract:

  • A user equipment (UE) can support communicating feedback for a transport block received over multiple TTIs.
  • The feedback is transmitted over a sidelink channel from a first UE to a second UE.
  • The transport block may be repeated multiple times and span multiple TTIs.
  • Both the first and second UEs identify the TTIs and determine resources for the feedback channel based on the index of the TTI.
  • The first UE then transmits feedback to the second UE regarding the reception of the transport block over the determined resources.

Potential applications of this technology:

  • Wireless communication systems that involve multiple UEs communicating with each other.
  • Sidelink communication scenarios where feedback on the reception of transport blocks is necessary.
  • Networks that require efficient and reliable communication between UEs.

Problems solved by this technology:

  • Efficient transmission of feedback for transport blocks received over multiple TTIs.
  • Ensuring accurate reception of transport blocks by providing feedback to the transmitting UE.
  • Optimizing resource allocation for the sidelink feedback channel.

Benefits of this technology:

  • Improved reliability and accuracy of communication between UEs.
  • Efficient utilization of resources by determining the appropriate resources for the feedback channel.
  • Enhanced performance of wireless communication systems by enabling effective feedback mechanisms.


Original Abstract Submitted

Methods, systems, and devices for wireless communications are described. A user equipment (UE) may support communicating sidelink feedback for a transport block communicated over multiple transmission time intervals (TTIs). For example, a first UE may receive one or more repetitions of a transport block from a second UE over a sidelink channel, where the one or more repetitions of the transport block may together span multiple TTIs. Each of the first UE and the second UE may identify at least one of the TTIs and may determine one or more resources of a sidelink feedback channel based on an index of the at least one TTI. The first UE may transmit, to the second UE, feedback pertaining to the reception of the one or more repetitions of the transport block over the determined one or more resources.
