METHOD AND APPARATUS FOR NR V2X SIDELINK HARQ PROCEDURE - A simplified explanation of the abstract
This abstract first appeared for US patent application 18469511 titled 'METHOD AND APPARATUS FOR NR V2X SIDELINK HARQ PROCEDURE
Simplified Explanation
The patent application describes apparatuses and methods for obtaining and providing Hybrid Automatic Repeat Request Acknowledgement (HARQ-ACK) information. HARQ-ACK information is used in wireless communication systems to acknowledge the successful reception of data.
- The method involves receiving a configuration for a slot offset value, which determines the timing of the transmission of HARQ-ACK information.
- A Physical Sidelink Shared Channel (PSSCH) is received over multiple sub-channels in a first slot. The PSSCH includes a transport block (TB) containing data.
- The method determines a second slot, referred to as the earliest slot, which has resources available for the transmission of a Physical Sidelink Feedback Channel (PSFCH).
- The PSFCH carries the HARQ-ACK information in response to the reception of the TB.
- The PSFCH is transmitted in the second slot, which is after the first slot by a number of slots equal to the slot offset value.
Potential applications of this technology:
- Wireless communication systems: The invention can be applied in various wireless communication systems, such as cellular networks, to improve the reliability and efficiency of data transmission.
Problems solved by this technology:
- Efficient HARQ-ACK transmission: The invention solves the problem of efficiently transmitting HARQ-ACK information in wireless communication systems by determining the timing and resources for the transmission.
Benefits of this technology:
- Improved reliability: By efficiently transmitting HARQ-ACK information, the invention improves the reliability of data transmission in wireless communication systems.
- Enhanced efficiency: The invention optimizes the use of resources by determining the earliest slot for PSFCH transmission, leading to improved efficiency in wireless communication systems.
Original Abstract Submitted
Apparatuses and methods for obtaining and providing hybrid automatic repeat request acknowledgement (HARQ-ACK) information. A method for providing HARQ-ACK information includes receiving a configuration for a slot offset value and receiving a physical sidelink shared channel (PSSCH) over a number of sub-channels in a first slot. The PSSCH includes a transport block (TB). The method includes determining a second slot as an earliest slot with resources for transmission of a physical sidelink feedback channel (PSFCH) that is after the first slot by a number of slots equal to the slot offset value. The PSFCH includes the HARQ-ACK information that is in response to reception of the TB. The method further includes transmitting the PSFCH in the second slot.
