Abstract
Methods for operating a communications device that communicates via inductive coupling, methods for operating an NFC device, and a communications device that communicates via inductive coupling are disclosed. In an embodiment, a method involves at the communications device, shifting a first transmission phase to obtain an updated transmission phase in response to information from a corresponding reader device, which indicates that active load modulation (ALM) communications between the communications device and the corresponding reader device under the first transmission phase fail, at the communications device, conducting subsequent ALM communications with the corresponding reader device under the updated transmission phase, in response to that the subsequent ALM communications under the updated transmission phase are successfully conducted between the communications device and the corresponding reader device, obtaining a new training data point based on the updated transmission phase, and training the communications device in response to the new training data point.
