RESOURCE ALLOCATION FOR FEEDBACK CHANNELS IN SIDELINK COMMUNICATIONS - A simplified explanation of the abstract

This abstract first appeared for US patent application 18137200 titled 'RESOURCE ALLOCATION FOR FEEDBACK CHANNELS IN SIDELINK COMMUNICATIONS

Simplified Explanation

This patent application is about implementing resource allocations for feedback channels in sidelink communications. It describes a method for a User Equipment (UE) to receive and transmit information over a sidelink with another UE.

  • The UE can receive a physical sidelink control channel (PSCCH) or a physical sidelink shared channel (PSSCH) transmission over the sidelink.
  • The UE can allocate a set of resource elements within an interlace, which includes multiple resource blocks, to carry physical sidelink feedback channel (PSFCH) content associated with the received transmission.
  • The set of resource elements includes a first resource element in a first resource block and a second resource element in a second resource block.
  • The UE then transmits the PSFCH content carried by the set of resource elements as a PSFCH transmission to the second UE.

Overall, this patent application presents a method for efficient resource allocation in sidelink communications, allowing UEs to exchange feedback and information over a sidelink.


Original Abstract Submitted

Some aspects of this disclosure relate to apparatuses and methods for implementing resource allocations for feedback channels in sidelink communications. A UE can be configured to receive a physical sidelink control channel (PSCCH) transmission or a physical sidelink shared channel (PSSCH) transmission over a sidelink between the UE and a second UE for sidelink communication. The UE can allocate a set of resource elements within an interlace including multiple resource blocks to carry physical sidelink feedback channel (PSFCH) content associated with the received PSCCH transmission or PSSCH transmission, where the set of resource elements includes a first resource element in a first resource block of the interlace, and a second resource element in a second resource block of the interlace. The UE can be further configured to transmit the PSFCH content carried by the set of resource elements as a PSFCH transmission to the second UE.
