  • repetition repetition
  • HARQ is a technology that combines forward error correction (Forward Error Correction, FEC) and automatic repeat request (Automatic Repeat reQuest, ARQ) methods. By adding redundant information, FEC enables the receiving end to correct some errors, thereby reducing the number of retransmissions.
  • FEC Forward Error Correction
  • ARQ Automatic Repeat reQuest
  • the receiver will request the sender to resend the data through the ARQ mechanism.
  • the receiving end uses an error detection code, usually a cyclic redundancy check (Cyclic Redundancy Check, CRC) to detect whether the received data packet is wrong. If there is no error, the receiving end will send an ACK to the sending end, and after receiving the ACK, the sending end will send the next data packet. If an error occurs, the receiving end will discard the data packet and send a NACK to the sending end. After receiving the NACK, the sending end will resend the same data.
  • CRC Cyclic Redundancy Check
  • the ARQ mechanism adopts the method of discarding data packets and requesting retransmission. Although the wrong data packets cannot be decoded correctly, they contain useful information. If these data packets are directly discarded, the useful information in them will also be lost.

If it still fails, repeat the process of "request for retransmission and then perform soft merge".

Abstract

La présente invention concerne un procédé de transmission et un terminal. En cas de collision de ressources entre une première transmission et une seconde transmission, ledit procédé suppose d'effectuer une première opération lors de la première transmission. La première opération comprend au moins une des actions suivantes : la transmission d'une version d'une transmission répétée au cours de la première transmission pendant laquelle la collision de ressources s'est produite ; l'abandon de la transmission de la version d'une transmission répétée pendant laquelle la collision de ressources s'est produite au cours de la première transmission ; la transmission de toutes les versions d'une transmission répétée non transmise au cours de la première transmission ; l'abandon de la transmission de toutes les versions d'une transmission répétée non transmise au cours de la première transmission ; la transmission d'une version d'une transmission répétée non transmise au cours de la première transmission pendant laquelle aucune collision de ressources ne s'est produite ; et l'abandon de la transmission de la version d'une transmission répétée non transmise au cours de la première transmission pendant laquelle aucune collision de ressources ne s'est produite. La première transmission est une transmission répétée contenant au moins deux versions d'une transmission répétée du même bloc de transmission.
