INTERLACED PHYSICAL SIDELINK FEEDBACK CHANNEL MAPPING FOR WIDEBAND SIDELINK TRANSMISSIONS - A simplified explanation of the abstract

This abstract first appeared for US patent application 17816471 titled 'INTERLACED PHYSICAL SIDELINK FEEDBACK CHANNEL MAPPING FOR WIDEBAND SIDELINK TRANSMISSIONS

Simplified Explanation

The patent application describes systems, devices, and methods for mapping wideband sidelink (SL) resources to SL feedback resources. Here is a simplified explanation of the abstract:

  • The method involves a wireless communication performed by a user equipment (UE).
  • The UE receives SL communication based on a first interlace of resource blocks (RBs) and two or more RB-sets of a shared frequency band.
  • The UE transmits SL feedback communication for the SL communication using a second interlace of RBs and resources from at least one RB-set of the two or more RB-sets.
  • The transmission of SL feedback communication is based on a mapping of the two or more RB-sets to the at least one RB-set.

Potential Applications:

  • This technology can be applied in wireless communication systems, particularly in the context of sidelink communication.
  • It can be used in various wireless devices such as smartphones, tablets, IoT devices, etc., that support SL communication.

Problems Solved:

  • The technology solves the problem of efficiently mapping wideband sidelink resources to SL feedback resources.
  • It addresses the challenge of optimizing resource allocation and utilization in SL communication.

Benefits:

  • The mapping of RB-sets to RB-sets allows for efficient utilization of resources, improving the overall performance of SL communication.
  • It enables reliable and effective SL feedback communication, enhancing the quality of wireless communication systems.
  • The technology can improve the capacity and throughput of wireless networks by optimizing resource allocation.


Original Abstract Submitted

Systems, devices, and methods for mapping wideband sidelink (SL) resources to SL feedback resources are provided. For example, a method of wireless communication performed by a user equipment (UE) comprises: receiving, based on at least a first interlace of resource blocks (RBs) and based on two or more RB-sets of a shared frequency band, a SL communication; and transmitting, using at least a second interlace of RBs and using resources from at least one RB-set of the two or more RB-sets of the shared frequency band, a SL feedback communication for the SL communication. In some aspects, the transmitting the SL feedback communication is based on a mapping of the two or more RB-sets to the at least one RB-set.
