CODEBOOK CONSTRUCTION FOR POINT-TO-MULTIPOINT OPERATION IN TELECOMMUNICATION SYSTEMS - A simplified explanation of the abstract

This abstract first appeared for US patent application 18260634 titled 'CODEBOOK CONSTRUCTION FOR POINT-TO-MULTIPOINT OPERATION IN TELECOMMUNICATION SYSTEMS

Simplified Explanation

This disclosure presents methods and processes to allow a user equipment (UE) to map a hybrid automatic retransmission request-acknowledgement (HARQ-ACK) feedback to one or more HARQ-ACK sub-codebooks for received services. The one or more HARQ-ACK sub-codebooks can be concatenated into one HARQ-ACK codebook and then communicated to a communication node, when those services use a HARQ-ACK feedback that is scheduled for the same time instance. Various methods can be used for the concatenation order depending on the number of multicast and broadcast services (MBS) for which HARQ feedback is to be provided, and depending on whether HARQ-ACK feedback is to be sent for unicast services at the scheduled time instance. The concatenation order can utilize an increasing order or a decreasing order of the concatenation order parameters.

  • Methods and processes for a UE to map HARQ-ACK feedback to HARQ-ACK sub-codebooks
  • Concatenation of HARQ-ACK sub-codebooks into one HARQ-ACK codebook
  • Communication of the concatenated codebook to a communication node
  • Different concatenation orders based on the number of MBS services and scheduled time instances for feedback
      1. Potential Applications
  • Wireless communication systems
  • 5G networks
  • Internet of Things (IoT) devices
      1. Problems Solved
  • Efficient mapping of HARQ-ACK feedback for multiple services
  • Optimization of HARQ feedback communication
  • Improved reliability in wireless communication
      1. Benefits
  • Enhanced performance in HARQ-ACK feedback transmission
  • Better utilization of resources in communication systems
  • Increased reliability and efficiency in data transmission
