INDICATION OF ASYMMETRIC DEFAULT OPERATING FREQUENCIES FOR BIDIRECTIONAL COMMUNICATIONS - A simplified explanation of the abstract

This abstract first appeared for US patent application 18158749 titled 'INDICATION OF ASYMMETRIC DEFAULT OPERATING FREQUENCIES FOR BIDIRECTIONAL COMMUNICATIONS

Simplified Explanation

This patent application describes a system for indicating asymmetric default operating frequencies (DOFs) for bidirectional communications. The system includes a first device that can report to a second device whether it is using the same DOF or different DOFs for communications in different transmission directions.

  • The first device can inform the second device about its use of DOFs for bidirectional communications.
  • The second device can use beam correspondence-based beam relationships if the DOFs are the same and the resource block allocations for both transmission directions are closely matched in frequencies.
  • If the DOFs are different, the second device can adjust a codebook parameter or use an appropriate antenna panel.
  • The second device can also direct the first device to use antenna subarrays with similar DOFs.

Potential applications of this technology:

  • Wireless communication systems
  • Cellular networks
  • Internet of Things (IoT) devices
  • Satellite communications

Problems solved by this technology:

  • Efficient bidirectional communication in wireless systems
  • Optimizing resource allocation and beam relationships based on DOFs
  • Improving overall communication performance and reliability

Benefits of this technology:

  • Enhanced bidirectional communication capabilities
  • Improved resource allocation and beamforming techniques
  • Increased efficiency and reliability in wireless communication systems


Original Abstract Submitted

This disclosure provides systems, methods and apparatus, including computer programs encoded on computer storage media, for indication of asymmetric default operating frequencies (DOFs) for bidirectional communications. In one aspect, a first device may report to the second device that the first device is using either a same DOF for communications in different transmission directions or different DOFs for the different transmission directions. Based on the reported DOF(s), the second device may use beam correspondence-based beam relationships on the different transmission directions if the DOFs are the same and resource block allocations for the communications in both transmission directions are closely matched in frequencies. Alternatively, if the DOFs are different for the different transmission directions, the second device may adjust either a codebook parameter or may use an appropriate antenna panel. Additionally, or alternatively, the second device may direct the first device to use respective antenna subarrays with similar DOFs.
