Title (EN) METHOD AND DEVICE FOR REPORTING A POWER HEADROOM REPORT
(FR) PROCÉDÉ ET DISPOSITIF DE CRÉATION DE RAPPORT DE MARGE DE PUISSANCE
Abstract:
(EN) The present invention provides a method and device for reporting a Power Headroom Report (PHR), comprises: based on the type of PUCCH to be transmitted, determining the type of the PHR; based on the type of PHR, determining a corresponding power headroom and reporting the PHR. By applying this technical solution, the base station can acquire the power headroom in the power headroom report after acquiring the power headroom report, and then be aware of the usage of power for transmitting Physical Uplink Control Channel (PUCCH) from User Equipment (UE) based on the acquired power headroom, thereby, the base station can configure the number of serving cells and the feedback mode of Channel State Information (CSI) better based on the usage of power for transmitting PUCCH; meantime, the base station determines whether or not to bind the Hybrid Automatic Retransmission Request - Acknowledgement (HARQ-ACK).
(FR) La présente invention concerne un procédé et un dispositif de création d'un rapport de marge de puissance (PHR). Le procédé consiste à : déterminer le type du PHR d’après le type de PUCCH devant être transmis ; et déterminer une marge de puissance correspondante et rapporter le PHR d’après le type de PHR. La mise en œuvre de cette solution technique permet à la station de base d’acquérir la marge de puissance contenue dans le rapport de marge de puissance après acquisition de ce dernier, et de connaître ensuite la puissance qui est utilisée pour transmettre un canal de commande de liaison montante physique (PUCCH) depuis un équipement d’utilisateur (UE) d’après la marge de puissance acquise. La station de base peut ainsi mieux configurer le nombre de cellules de desserte et le mode de rétroaction d'informations d'état de canal (CSI) d’après la puissance utilisée pour transmettre un PUCCH. Dans le même temps, la station de base détermine s'il faut ou non associer l'accusé de réception de requête automatique de retransmission hybride (HARQ-ACK).
