Title (EN) WIRELESS POWER TRANSMITTER TO RECEIVER COMMUNICATION DURING POWER TRANSFER PHASE
(FR) COMMUNICATION ÉMETTEUR-RÉCEPTEUR DE PUISSANCE SANS FIL PENDANT UNE PHASE DE TRANSFERT DE PUISSANCE
Abstract:
(EN) In accordance with some embodiments of the present invention a method of communicating with a wireless power receiver during a power transfer phase is presented. The method includes receiving from the wireless power receiver an receive packet; and transmitting an transmit packet within a time after receipt of the receive packet, the transmit packet being other than an acknowledgment packet. A method of communicating with a wireless power transmitter during a power transfer phase includes transmitter to the wireless power transmitter a receive packet; enabling a decoder within a time period; and if a start bit of a transmit packet is received, receiving the transmit packet, wherein the transmit packet is other than an acknowledgment packet.
(FR) Selon certains modes de réalisation, la présente invention concerne un procédé de communication avec un récepteur de puissance sans fil pendant une phase de transfert de puissance. Le procédé consiste à recevoir, en provenance du récepteur d'énergie sans fil, un paquet de réception ; et à transmettre un paquet de transmission dans une période de temps après réception du paquet de réception, le paquet de transmission étant différent d'un paquet d'accusé de réception. Un procédé de communication avec un émetteur de puissance sans fil pendant une phase de transfert de puissance consiste à transmettre un paquet de réception à l'émetteur de puissance sans fil ; à activer un décodeur dans une période de temps ; et à recevoir, si un bit de départ d'un paquet de transmission est reçu, le paquet de transmission, le paquet de transmission étant différent d'un paquet d'accusé de réception.
