PUCCH Repetition to Increase the Reliability of PUCCH Transmission - A simplified explanation of the abstract

This abstract first appeared for US patent application 18680544 titled 'PUCCH Repetition to Increase the Reliability of PUCCH Transmission

The abstract describes a patent application for a user equipment (UE) that can enhance the reliability of transmitting a Physical Uplink Control Channel (PUCCH) by sending multiple copies of the PUCCH in a repetition pattern across one or more slots. The UE can transmit multiple copies within a single slot in an intra-slot mode, with or without frequency hopping, and the network can configure the number of copies and the timing between them. In an inter-slot mode, one copy is sent per slot, and different copies can be transmitted in different directions based on a spatial consistency pattern. The UE can repeat the transmission of PUCCHs to different Transmission-Reception Points (TRPs) with varying timing advances and transmit power levels.

The UE can increase the reliability of PUCCH transmission by repeating copies according to a configurable pattern.
Repetition can occur within a slot or across slots, with variations in the number of copies and timing between transmissions.
Different copies of the PUCCH can be sent in different directions based on a spatial consistency pattern.
The UE can transmit repeated PUCCHs to different TRPs using different timing advances and power levels.
The network can configure the repetition pattern to optimize transmission reliability.

Potential Applications: - Enhanced reliability in transmitting control signals in wireless communication systems. - Improved performance in scenarios with high interference or fading.

Problems Solved: - Addressing challenges related to the reliability of PUCCH transmission in wireless communication systems. - Mitigating the impact of interference and fading on control channel transmission.

Benefits: - Increased reliability and robustness of PUCCH transmission. - Enhanced performance in challenging wireless communication environments. - Improved overall communication quality and efficiency.

Commercial Applications: Title: Enhanced Wireless Communication Reliability with PUCCH Repetition This technology could find applications in telecommunications companies, IoT devices, and other industries reliant on wireless communication systems. The enhanced reliability of PUCCH transmission can lead to improved network performance, reduced packet loss, and better overall user experience.

Questions about PUCCH Repetition: 1. How does the repetition pattern of PUCCH transmission improve reliability in wireless communication systems? 2. What are the potential drawbacks or limitations of using repeated PUCCH transmissions for reliability enhancement?

Original Abstract Submitted

A user equipment (UE) may increase the reliability of transmission of a Physical Uplink Control Channel (PUCCH) by transmitting repeated copies of the PUCCH, according to a repetition pattern spanning one or more slots. In an intra-slot mode, more than one copy may be transmitted within each configured slot, with or without frequency hopping. The number of copies as well as a temporal gap between the transmission of successive copies may be configured by the network. The repetition pattern may or may not be interrupted by slot boundaries. In an inter-slot mode, one copy is transmitted per configured slot. Different copies may be transmitted in different directions, according to a spatial consistency pattern. The UE may perform repeated transmission of PUCCHs to different Transmission-Reception Points (TRPs) using respectively different timing advances and/or transmit power levels.
