摘要： Embodiments of this application provide a data transmission method and apparatus, to resolve a multiple access interference problem in a multi-user communication system. A first terminal device performs data transmission in one frequency hopping cycle based on a frequency corresponding to an element in a first sequence, where the one frequency hopping cycle includes M frequency hopping moments, a frequency corresponding to the first terminal device at a first frequency hopping moment is a frequency corresponding to a first element, a frequency corresponding to the first terminal device at an ith frequency hopping moment is a frequency corresponding to an element obtained by cyclically moving from the first element leftward (or rightward) for i-1 times according to a specified rule, i is a positive integer from 2 to M, and M is a positive integer greater than or equal to 2. In this way, the first terminal device may have a plurality of frequency hopping moments in the one frequency hopping cycle, and may have a plurality of optional frequency hopping frequencies in frequency domain, thereby resolving the multiple access interference problem in the multi-user communication system.

摘要： In future radio communication systems, uplink control channels will be transmitted properly. A user terminal has a receiving section that receives frequency hopping information, which indicates whether frequency hopping for an uplink control channel in one slot is enabled or not, and receives information that indicates the number of slots for the uplink control channel, and a control section that, when the number of slots is greater than one, controls repetition transmission of the uplink control channel, over a plurality of slots, by applying at least one of a spreading factor of a time-domain orthogonal cover code, a configuration of a demodulation reference code, and a base sequence, to the uplink control channel, based on the frequency hopping information.

摘要： La présente invention concerne un procédé (50) d'émission, par un terminal (10), d'un message à destination d'une station de réception (20) d'un système de communication sans fil, ledit message devant être émis sur un canal partagé sur lequel l'émission de messages est effectuée au début d'intervalles de temps prédéterminés, dits « slots », caractérisé en ce que ledit procédé (50) d'émission comporte :
- un encodage (51) de données à inclure dans le message à émettre,
- une répartition (52) des données encodées entre Nb sous-messages du message à émettre, Nb étant un nombre entier supérieur ou égal à deux,
- une sélection (53) d'un slot pour l'émission dudit message,
- une sélection (54) de Nb fréquences d'émission, associées respectivement aux Nb sous-messages du message,
- une émission (55) du message au début du slot sélectionné, en émettant successivement les sous-messages sur leurs fréquences d'émission associées respectives.
