A method for interference randomization of physical uplink control channel (PUCCH), used in long term evolution (LTE) system. When a plurality of user equipments (UEs) are multiplexed in a PUCCH to transmit uplink control signaling, the difference of indexes of control channel resources used by any two UEs in the first timeslot of the PUCCH is different from that in the second timeslot of the PUCCH. The present invention can realize interference randomization among the UEs that are multiplexed in the same PUCCH.

Procédé d'échantillonnage aléatoire d'interférences sur un canal physique de contrôle en voie montante PUCCH, utilisé dans un système Long Term Evolution (LTE), lorsque des terminaux multiples multiplexent le PUCCH pour transmettre des signalisations de contrôle en voie montante, la différence d'indice des ressources du canal de contrôle utilisées par deux terminaux quelconques pendant le premier créneau temporel du PUCCH étant différente de la différence d'indice des ressources du canal de contrôle utilisées par les deux terminaux pendant le deuxième créneau temporel du PUCCH. L'invention est capable de réaliser l'échantillonnage aléatoire d'interférences entre des UE qui multiplexent le même PUCCH.
