WIRELESS COMMUNICATION METHOD, TERMINAL DEVICE AND NETWORK DEVICE - A simplified explanation of the abstract

This abstract first appeared for US patent application 18221780 titled 'WIRELESS COMMUNICATION METHOD, TERMINAL DEVICE AND NETWORK DEVICE

Simplified Explanation

This patent application describes a wireless communication method that allows a terminal device to provide feedback for multicast or broadcast transmissions. The method involves the terminal device determining Hybrid Automatic Repeat Request (HARQ) feedback information for a specific identifier associated with certain uplink control channel resources. The feedback mode only includes Non-Acknowledgement (NACK)-included HARQ feedback information. The terminal device then sends the NACK-included HARQ feedback information on one of the uplink control channel resources.

  • The method allows for providing feedback for multicast or broadcast transmissions.
  • The feedback is based on HARQ feedback information for a specific identifier.
  • The feedback mode only includes NACK-included HARQ feedback information.
  • The feedback is sent on one of the uplink control channel resources.
  • This method ensures the reliability of service transmission by allowing the network to determine if data retransmission is needed based on the feedback.


Original Abstract Submitted

Provided in the embodiments of the present disclosure are a wireless communication method, a terminal device and a network device. The method includes: a terminal device determining Hybrid Automatic Repeat Request (HARQ) feedback information corresponding to a first Group Radio Network Temporary Identifier (G-RNTI), wherein the first G-RNTI is associated with one or multiple Physical Uplink Control Channel (PUCCH) resources configured for a first feedback mode, and the first feedback mode includes an HARQ feedback mode only feeding back Non-Acknowledgement (NACK)-included HARQ feedback information; and the terminal device sending, on one of the one or multiple PUCCH resources, NACK-included HARQ feedback information corresponding to the first G-RNTI. By the solution provided in the present disclosure, feedback can be provided for multicast or broadcast, such that a network may determine, according to the feedback, whether data retransmission is needed, thereby ensuring the reliability of service transmission.
