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

This abstract first appeared for US patent application 20240323966 titled 'PUCCH Repetition to Increase the Reliability of PUCCH Transmission

Simplified Explanation

A user equipment (UE) can improve the reliability of transmitting a physical uplink control channel (PUCCH) by sending multiple copies of the PUCCH in a pattern across one or more slots.

• The UE can transmit repeated copies of the PUCCH within each configured slot, with or without frequency hopping.
• The network can configure the number of copies and the time gap between successive transmissions.
• The repetition pattern may or may not be interrupted by slot boundaries.
• In an inter-slot mode, one copy is transmitted per configured slot, possibly in different directions based on a spatial consistency pattern.
• The UE can transmit multiple PUCCHs to different transmission-reception points (TRPs) with varying timing advances and power levels.

Key Features and Innovation

• Repetition of PUCCH for increased reliability.
• Configurable number of copies and timing between transmissions.
• Intra-slot and inter-slot transmission modes.
• Spatial consistency pattern for direction of transmission.
• Varying timing advances and power levels for different TRPs.

Questions about PUCCH Transmission

How does the repetition pattern of PUCCH transmissions impact reliability?

The repetition pattern of PUCCH transmissions can enhance reliability by providing redundant copies of the control channel, reducing the risk of errors in communication.

What are the potential drawbacks of transmitting multiple copies of the PUCCH?

Transmitting multiple copies of the PUCCH may increase resource consumption and spectral efficiency, which could impact overall network performance.

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.
