FEEDBACK TECHNIQUES FOR MULTICAST AND UNICAST COMMUNICATIONS - A simplified explanation of the abstract

This abstract first appeared for US patent application 17389160 titled 'FEEDBACK TECHNIQUES FOR MULTICAST AND UNICAST COMMUNICATIONS

Simplified Explanation

Methods, systems, and devices for wireless communications are described in this patent application. The invention focuses on a user equipment (UE) receiving a feedback configuration from a base station for providing feedback for downlink communications. The UE then determines whether the feedback processes have a multicast-only configuration for multicast data communications or a multicast-or-unicast configuration for either multicast or unicast data communications. Based on this configuration, the UE decodes transmissions associated with the feedback processes and determines a feedback codebook. The UE also monitors for retransmissions of multicast data communications based on the feedback process configuration.

  • The patent application describes a method for configuring feedback processes in wireless communications.
  • The user equipment (UE) receives a feedback configuration from a base station.
  • The UE determines if the feedback processes have a multicast-only or multicast-or-unicast configuration.
  • Based on the configuration, the UE decodes transmissions and determines a feedback codebook.
  • The UE monitors for retransmissions of multicast data communications based on the feedback process configuration.

Potential Applications

This technology has potential applications in the field of wireless communications, particularly in the context of multicast data communications. It can be used in various industries and scenarios where efficient and reliable wireless communication is required, such as:

  • Broadcasting: This technology can be used in broadcasting systems to efficiently transmit multicast data to multiple receivers.
  • Video Streaming: It can improve the quality and reliability of multicast video streaming services, allowing for better user experience.
  • IoT Networks: In Internet of Things (IoT) networks, where multiple devices need to receive the same data simultaneously, this technology can enhance the efficiency and reliability of multicast communications.

Problems Solved

The technology described in this patent application addresses several problems in wireless communications:

  • Efficient Multicast: By providing a feedback configuration specifically designed for multicast data communications, the invention enables more efficient and reliable transmission of multicast data to multiple receivers.
  • Flexibility: The multicast-or-unicast configuration allows the UE to handle both multicast and unicast data communications, providing flexibility in different communication scenarios.
  • Retransmission Monitoring: The ability to monitor retransmissions of multicast data communications based on the feedback process configuration helps ensure the reliability of the transmitted data.

Benefits

The technology presented in this patent application offers several benefits:

  • Improved Efficiency: By optimizing the feedback configuration for multicast data communications, the invention enhances the efficiency of wireless communication systems.
  • Enhanced Reliability: The ability to monitor retransmissions based on the feedback process configuration improves the reliability of multicast data communications.
  • Flexibility and Compatibility: The multicast-or-unicast configuration allows the UE to handle both multicast and unicast data communications, making it compatible with various communication scenarios and systems.


Original Abstract Submitted

Methods, systems, and devices for wireless communications are described in which a user equipment (UE) may receive a feedback configuration for providing feedback for downlink communications from a base station. Based on the feedback configuration, the UE may determine whether one or more feedback processes has a multicast-only configuration for multicast data communications, or a multicast-or-unicast configuration for either multicast data communications or unicast data communications. The UE may decode one or more transmissions associated with the one or more feedback processes based on the multicast-only or multicast-or-unicast configuration, and may determine a feedback codebook based on the multicast-only or multicast-or-unicast configuration of the one or more feedback processes. The UE may monitor for retransmissions of one or more multicast data communications based on the feedback process configuration.
