  • the UCI and the RS structure of the PUCCHs of lengths 4 and 5 are respectively transmitted, as shown in PUCCH1 and PUCCH2 in FIG. 9; wherein, the PUCCH is in each In the time slot, the last symbol in the uplink region ends the transmission, that is, if the uplink region is larger than the transmission length, the last symbol transmission in the uplink region is always occupied, and of course, the first symbol in the uplink region may also be used.
  • the transmission is started, that is, if the uplink area is larger than the transmission length, the first few symbol transmissions of the uplink area are always occupied.

  • the PUCCH can also be transmitted by using other symbol length transmission/formats, for example, any integer length of 4 to 14, and the working mode is the same; the above only takes the PUCCH to occupy the uplink area as an example, of course, the uplink area.
  • the transmission length of the PUCCH may be determined according to the size of the area used for transmitting the PUCCH in the uplink area. When the signaling configuration, the transmission length of the PUCCH may be smaller than the foregoing UL area or used. The size of the area in which the PUCCH is transmitted works in the same way.

Abstract

La présente invention concerne un procédé d'émission et un procédé de réception de canal de commande de liaison montante, un dispositif, un terminal et une station de base. Le procédé d'émission comporte les étapes consistant à: déterminer une pluralité de créneaux temporels cibles pour émettre des informations de commande de liaison montante à renvoyer, les informations de commande de liaison montante à renvoyer étant émises dans les créneaux temporels cibles au moyen d'un canal de commande de liaison montante; déterminer, dans chaque créneau temporel cible, la longueur ou le format d'émission du canal de commande de liaison montante portant les informations de commande de liaison montante à renvoyer; et émettre, d'après la longueur ou le format de transmission déterminé(e) du canal de commande de liaison montante, le canal de commande de liaison montante portant les informations de commande de liaison montante à renvoyer dans chaque créneau temporel cible.
