Abstract

La présente demande peut s'appliquer au domaine technique des communications. L'invention concerne un procédé de détermination de puissance de repli et un procédé de réglage de puissance d'émission. Le procédé de détermination de puissance de repli comprend : l'identification d'un scénario de service actuel comme étant un scénario de service vocal ; la détermination du format vocal du scénario de service vocal, et la détermination de la proportion de liaison montante de paquets vocaux selon le format vocal ; et la détermination de la puissance de repli correspondant à la proportion de liaison montante. Sur la base de la détermination d'une solution pour abaisser la valeur SAR, la présente demande détermine la puissance de repli, ce qui permet d'augmenter la puissance d'émission et de résoudre le problème technique qui est que satisfaire aux exigences de surface de valeur SAR lors de la détermination d'une solution pour abaisser la valeur de SAR entraîne une réduction excessive de la puissance d'émission.
