摘要：Aspects relate to improved mechanisms for updating parameter values forcommunications between a DH and a remote NFC endpoint. In one example, a DHassociated with a NFC device may be configured to determine that one or more
parameter values included in a parameter selection request message are different thanone or more corresponding parameter values used during discovery of a remote NFCendpoint using a frame RF interface, and communicate the parameter values to a NFCController using a parameter update message. A NFCC associated with a NFC device maybe configured to receive, using a NFC-DEP interface, a parameter selection requestmessage including one or more parameters, determine to implement one or moreparameter changes based on the received one or more parameters, and communicate anactivation message to a DH indicating values to which the NFC Controller changed theone or more parameter values.
