SEPARATE HYBRID AUTOMATIC RECEIPT REQUEST ACKNOWLEDGEMENT FOR DOWNLINK TRANSMISSIONS - A simplified explanation of the abstract

This abstract first appeared for US patent application 18264721 titled 'SEPARATE HYBRID AUTOMATIC RECEIPT REQUEST ACKNOWLEDGEMENT FOR DOWNLINK TRANSMISSIONS

Simplified Explanation

This disclosure describes a system for wireless communication that allows multiple user equipments (UEs) to cooperate as a virtual UE for downlink transmissions using hybrid automatic repeat request (HARQ) acknowledgement.

• Multiple UEs work together as a virtual UE to communicate with a base station.
• The virtual UE generates acknowledgement codebooks to indicate acknowledgement status.
• The virtual UE decodes downlink transmissions and reports an acknowledgement indicator based on the decoding result.
• The acknowledgement indicator is selected from an acknowledgement codebook associated with the member UE.

• • Potential Applications:**

• 5G and future wireless communication systems
• IoT devices requiring efficient communication protocols

• • Problems Solved:**

• Enhances reliability and efficiency of downlink transmissions
• Allows for improved coordination among multiple UEs

• • Benefits:**

• Increased reliability in wireless communication
• Enhanced performance in HARQ processes
• Improved coordination among UEs for better network efficiency

Original Abstract Submitted

This disclosure provides systems, methods, and devices for wireless communication that support separate hybrid automatic receipt request (HARQ) acknowledgement by member user equipments (UEs) cooperating as a virtual UE for downlink transmissions. In a first aspect, a virtual UE may detect a downlink transmission, wherein the virtual UE includes two or more member UEs in communication with each other and configured to cooperate in communications with the serving base station. The virtual UE may generate one or more acknowledgement codebooks configured to indicate an acknowledgement status by the virtual UE. The virtual UE may attempt to decode the downlink transmission and report an acknowledgment indicator that reflects the result of the decoding. The acknowledgment indicator includes an acknowledgement state selected from an acknowledgement codebook associated with the member UE. Other aspects and features are also claimed and described.
