MULTIPLEXING UPLINK CONTROL INFORMATION (UCI) WITH MIXED PRIORITIES FOR A PHYSICAL UPLINK CONTROL CHANNEL (PUCCH) - A simplified explanation of the abstract

This abstract first appeared for US patent application 17441247 titled 'MULTIPLEXING UPLINK CONTROL INFORMATION (UCI) WITH MIXED PRIORITIES FOR A PHYSICAL UPLINK CONTROL CHANNEL (PUCCH)

Simplified Explanation

The patent application is about apparatuses and methods for implementing techniques for a user equipment (UE) to multiplex a first Hybrid Automatic Repeat Request (HARQ) of a first priority and a second HARQ of a second priority to form an initial Uplink Control Information (UCI) payload. The UE can select a Physical Uplink Control Channel (PUCCH) resource according to a PUCCH configuration and generate a second UCI payload by removing or replacing a portion of the initial UCI payload when its size is larger than the size of the PUCCH resource. The UE can encode at least a part of the second UCI payload including the first HARQ to generate an error correction code word. The UE then adds the error correction code word to the second UCI payload to generate a transmission UCI payload, which is transmitted to the base station.

• The patent application describes techniques for a UE to multiplex different HARQs to form an initial UCI payload.
• The UE can select a PUCCH resource based on a PUCCH configuration.
• If the size of the initial UCI payload is larger than the size of the selected PUCCH resource, the UE can generate a second UCI payload by removing or replacing a portion of the initial UCI payload.
• The UE can encode at least a part of the second UCI payload, including the first HARQ, to generate an error correction code word.
• The UE adds the error correction code word to the second UCI payload to form a transmission UCI payload, which is then transmitted to the base station.

Potential applications of this technology:

• This technology can be applied in wireless communication systems, particularly in the uplink transmission from user equipment to base stations.
• It can improve the efficiency of transmitting UCI payloads by multiplexing different HARQs and optimizing the use of PUCCH resources.

Problems solved by this technology:

• The technology solves the problem of efficiently transmitting UCI payloads when the size of the initial payload is larger than the available PUCCH resource.
• It addresses the challenge of multiplexing different HARQs to form an initial UCI payload.

Benefits of this technology:

• The technology allows for efficient use of PUCCH resources by selecting appropriate resources based on the PUCCH configuration.
• It improves the reliability of UCI transmission by encoding the UCI payload with an error correction code word.
• The technology enables multiplexing of different HARQs, which can improve the overall system performance and capacity.

Original Abstract Submitted

Some aspects of this disclosure relate to apparatuses and methods for implementing techniques for a user equipment (UE) to multiplex a first HARQ of a first priority and a second HARQ of a second priority to form an initial UCI payload. The UE can select a PUCCH resource accordingly to a PUCCH configuration, and generate a second UCI payload by removing or replacing at least a portion of the initial UCI payload when a size of the initial UCI payload is larger than a size of the PUCCH resource. The UE can encode at least a part of the second UCI payload including the first HARQ to generate an error correction code word. Afterwards, the UE can add the error correction code word to the second UCI payload to generate a transmission UCI payload, and transmit the transmission UCI payload to the base station.
