USER EQUIPMENT COOPERATION - A simplified explanation of the abstract
This abstract first appeared for US patent application 18026788 titled 'USER EQUIPMENT COOPERATION
Simplified Explanation
The patent application describes a method to improve the accuracy and efficiency of Hybrid Automatic Repeat Request (HARQ) feedback for a User Equipment (UE) communicating with a base station or multiple Transmit-Receive Points (TRPs) using multiple antenna panels.
- The apparatus receives Downlink Control Information (DCI) that schedules a Physical Downlink Shared Channel (PDSCH) to be received by a first set of antenna panels and indicates a second set of Physical Uplink Control Channel (PUCCH) repetitions for providing ACK/NACK feedback.
- The PDSCH is received through the first set of antenna panels.
- The apparatus transmits ACK/NACK feedback in the indicated second set of PUCCH repetitions based on the received PDSCH.
Potential Applications
- Wireless communication systems
- Cellular networks
- 5G networks
Problems Solved
- Improves the accuracy of HARQ feedback in wireless communication systems.
- Enhances the efficiency of HARQ feedback transmission for UEs communicating with base stations or TRPs.
Benefits
- Increases the reliability of communication between UEs and base stations/TRPs.
- Reduces the overhead and latency associated with HARQ feedback transmission.
- Optimizes the utilization of multiple antenna panels for improved signal reception.
Original Abstract Submitted
Aspects presented herein may improve the accuracy and/or the efficiency of HARQ feedback for a UE communicating with a base station or multiple TRPs using multiple antenna panels. In one aspect, an apparatus receives DCI scheduling a PDSCH to be received by a first plurality of panels and indicating a second plurality of PUCCH repetitions for providing ACK/NACK feedback. The apparatus receives the PDSCH through the first plurality of panels. The apparatus transmits ACK/NACK feedback in the indicated second plurality of PUCCH repetitions based on the received PDSCH.
