METHOD AND DEVICE FOR HARQ-BASED TRANSMISSION/RECEPTION FOR GROUP-COMMON TRANSMISSION IN WIRELESS COMMUNICATION SYSTEM - A simplified explanation of the abstract

This abstract first appeared for US patent application 18101481 titled 'METHOD AND DEVICE FOR HARQ-BASED TRANSMISSION/RECEPTION FOR GROUP-COMMON TRANSMISSION IN WIRELESS COMMUNICATION SYSTEM

Simplified Explanation

The abstract describes a method performed by a terminal in a wireless communication system. The method involves receiving a group-common transmission regarding a transport block (TB) from a network. The terminal then transmits hybrid automatic repeat request (HARQ) acknowledgement (ACK) or non-acknowledgement (NACK) information to the network based on whether the TB is successfully decoded. After a first round trip time (RTT) has lapsed since the transmission of the HARQ ACK/NACK information, the terminal receives a first transmission from the network. This first transmission can be either a group-common transmission or a terminal-specific transmission. If it is a terminal-specific transmission associated with the same HARQ process as the group-common transmission and the new data indicator (NDI) value is not toggled, it corresponds to a retransmission of the TB.

  • The method involves a terminal in a wireless communication system.
  • The terminal receives a group-common transmission regarding a transport block (TB) from a network.
  • The terminal transmits hybrid automatic repeat request (HARQ) acknowledgement (ACK) or non-acknowledgement (NACK) information to the network based on the successful decoding of the TB.
  • After a first round trip time (RTT), the terminal receives a first transmission from the network.
  • The first transmission can be a group-common transmission or a terminal-specific transmission.
  • If the first transmission is a terminal-specific transmission associated with the same HARQ process as the group-common transmission and the new data indicator (NDI) value is not toggled, it corresponds to a retransmission of the TB.

Potential Applications

  • This method can be applied in wireless communication systems to improve the reliability of data transmission.
  • It can be used in various wireless communication technologies such as 4G LTE, 5G, and beyond.

Problems Solved

  • The method solves the problem of efficiently handling retransmissions in wireless communication systems.
  • It ensures that retransmissions are only performed when necessary, based on the decoding success of the initial transmission.

Benefits

  • By transmitting HARQ ACK/NACK information, the method allows the network to determine whether the TB was successfully decoded.
  • The method reduces unnecessary retransmissions by considering factors such as the HARQ process and NDI value.
  • It improves the overall efficiency and reliability of data transmission in wireless communication systems.


Original Abstract Submitted

A method performed by a terminal in a wireless communication system according to an embodiment of the present disclosure comprises the steps of: receiving a group-common transmission regarding a TB from a network; transmitting hybrid automatic repeat request (HARQ) acknowledgement (ACK) or non-acknowledgement (NACK) information regarding the group-common transmission to the network, on the basis of whether the TB is successfully decoded; and receiving first transmission from the network after a first round trip time (RTT) has lapsed since transmission of the HARQ ACK/NACK information regarding the group-common transmission. The first transmission corresponds to group-common transmission or terminal-specific transmission. The first transmission may correspond to retransmission of the TB on the basis that the first transmission is terminal-specific transmission associated with the same HARQ process as the group-common transmission, and that a new data indicator (NDI) value is not toggled.
