METHOD AND APPARATUS FOR PERFORMING SIDELINK TRANSMISSION ON BASIS OF PUCCH PROCESSING TIME IN NR V2X - A simplified explanation of the abstract
This abstract first appeared for US patent application 17919902 titled 'METHOD AND APPARATUS FOR PERFORMING SIDELINK TRANSMISSION ON BASIS OF PUCCH PROCESSING TIME IN NR V2X
Simplified Explanation
The proposed patent application describes a method for wireless communication between devices. Here are the key points:
- The method involves a first device receiving information from a base station about a physical uplink control channel (PUCCH) resource and the time gap between a physical sidelink feedback channel (PSFCH) and the PUCCH.
- The first device transmits sidelink control information (SCI) to a second device through a physical sidelink control channel (PSCCH).
- Sidelink data is transmitted to the second device through a physical sidelink shared channel (PSSCH) related to the PSCCH.
- The first device determines a PSFCH resource based on the slot index and subchannel index related to the PSSCH.
- If the time gap between the determined PSFCH resource and the first PUCCH resource is smaller than the time gap between the PSFCH and the PUCCH, the first device drops transmission of a hybrid automatic repeat request (HARQ) feedback related to the sidelink data on the first PUCCH resource.
- The first device receives information from the base station about a second PUCCH resource, based on the dropped transmission of the HARQ feedback.
- An acknowledgment (ACK) related to the sidelink data is transmitted to the base station using the second PUCCH resource.
Potential applications of this technology:
- Wireless communication between devices in various industries such as telecommunications, IoT, and smart devices.
- Enhancing the efficiency and reliability of wireless communication in scenarios where sidelink data transmission is required.
Problems solved by this technology:
- Efficient utilization of resources by dropping unnecessary transmission of HARQ feedback on the first PUCCH resource.
- Improved reliability of sidelink data transmission by using a second PUCCH resource for transmitting acknowledgments.
Benefits of this technology:
- Increased efficiency in wireless communication by optimizing the use of resources.
- Improved reliability and performance of sidelink data transmission.
- Enhanced overall system capacity and throughput.
Original Abstract Submitted
Proposed is a method by which a first device performs wireless communication. The method may comprise the steps of: receiving, from a base station, information related to a first physical uplink control channel (PUCCH) resource and information related to a time gap between a physical sidelink feedback channel (PSFCH) and a PUCCH; transmitting sidelink control information (SCI) to a second device through a physical sidelink control channel (PSCCH); transmitting sidelink data to the second device through a physical sidelink shared channel (PSSCH) related to the PSCCH; determining a PSFCH resource on the basis of an index of a slot and an index of a subchannel which are related to the PSSCH, wherein, on the basis of the fact that a time gap between the determined PSFCH resource and the first PUCCH resource is smaller than the time gap between the PSFCH and the PUCCH, the first device drops transmission of a hybrid automatic repeat request (HARQ) feedback related to the sidelink data on the first PUCCH resource; receiving, from the base station, information related to a second PUCCH resource, on the basis of the transmission of the HARQ feedback being dropped; and transmitting an acknowledgment (ACK) related to the sidelink data to the base station on the basis of the second PUCCH resource.
