Multiplexing Of Configured Grant-UCI (CG-UCI) And Uplink Control Information (UCI) In Shared Frequency Bands - A simplified explanation of the abstract

This abstract first appeared for US patent application 18253239 titled 'Multiplexing Of Configured Grant-UCI (CG-UCI) And Uplink Control Information (UCI) In Shared Frequency Bands

Simplified Explanation

The patent application describes a wireless communication system that allows for the efficient multiplexing of different types of uplink control information (UCI) and configured grant-UCI (CG-UCI) with different priorities. Here are the key points:

  • The system involves a user equipment (UE) that identifies a situation where a physical uplink control channel (PUCCH) resource partially overlaps with a configured grant physical uplink shared channel (CG-PUSCH) resource, which have different priorities.
  • The UE determines the number of bits of low-priority UCI that can be multiplexed with high-priority CG-PUSCH transmission, low-priority CG-PUSCH transmission, or high-priority UCI, based on a threshold number of bits.
  • The UE combines the determined number of bits of low-priority UCI with the high-priority CG-PUSCH transmission, low-priority CG-PUSCH transmission, or high-priority UCI to create a multiplexed uplink transmission.
  • The multiplexed uplink transmission is then sent over either the PUCCH resource or the CG-PUSCH resource.

Potential applications of this technology:

  • Wireless communication systems and networks
  • Mobile devices and smartphones
  • Internet of Things (IoT) devices
  • Machine-to-machine communication

Problems solved by this technology:

  • Efficient utilization of limited resources in wireless communication systems
  • Effective multiplexing of different types of uplink control information with different priorities
  • Optimization of uplink transmission in scenarios where resources partially overlap

Benefits of this technology:

  • Improved efficiency and capacity of wireless communication systems
  • Enhanced performance and reliability of uplink transmissions
  • Better utilization of available resources, leading to improved overall system performance.


Original Abstract Submitted

Wireless communication systems and methods related to multiplexing of uplink control information (UCI) and configured grant-UCI (CG-UCI) of different priorities are provided. A user equipment (UE) determines that a physical uplink control channel (PUCCH) resource at least partially overlaps with a configured grant physical uplink shared channel (CG-PUSCH) resource, where the PUCCH resource and the CG-PUSCH resource are associated with different priorities. The UE, based on a threshold number of bits, a number of bits of a low-priority uplink control information (UCI) for multiplexing with at least one of a high-priority CG-PUSCH transmission, a low-priority CG-PUSCH transmission, or a high-priority UCI. The UE multiplexes the number of bits of the low-priority UCI with the at least one of the high-priority CG-PUSCH transmission, the low-priority CG-PUSCH transmission, or the high-priority UCI to generate a multiplexed uplink transmission, and transmits the multiplexed uplink transmission in the PUCCH resource or the CG-PUSCH resource.
