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

A method, an apparatus, and a computer program product for wireless communication are provided in connection with enabling a NFC-enabled device to discover and/or communicate with a TTF device. In one example, a NFC enabled device is equipped to initiate a RF field that is not modulated by the NFC-enabled device as part of a technology detection process, monitor the RF field for at least a portion of a wait duration, determine whether, during the wait duration, the RF field is modulated in a manner consistent with modulation characteristics of a NFC technology, and terminate the technology detection process upon the determination that the RF field is modulated a manner consistent with modulation characteristics of the NFC technology.

Aspects disclosed herein relate to enabling specification of different bit rates in each direction for NFC peer communications. In one example, a target NFC device may be configured to receive a parameter selection request including a first bit rate value to be used for transmissions from an initiator NFC device to the target NFC device and a second bit rate value to be used in the other direction, and to function in either a first or a second target sub-state based on the first bit rate value. In another example, an initiator NFC device may be configured to determine a first bit rate value to be used for transmissions from an initiator NFC device to a target NFC device and a second bit rate value to be used in the other direction, and to transmit the first and second bit rate values in a parameter selection request message.

Aspects disclosed herein relate to providing a mechanism by which an NFCC can provide a DH with sufficient information to begin RF Discovery on behalf of a NFCEE. In one example, with a NFC device a DH may be configured to receive a discovery request notification from a NFCC indicating a NFCEE is requesting that the DH perform a discovery process. The discovery request notification may include information formatted to simplify the creation of a RF discovery command. The DH may further be configured to determine whether to generate the RF discovery command using the information included in the discovery request notification, generate the DH based discover command using the information included in the discovery request notification upon a determination to include the received information, and transmit the RF discovery command to the NFCC.

Exemplary embodiments are directed to wireless electronic devices. A method may comprise receiving a wireless signal with an antenna and identifying one of a wireless charging module and a near-field communication module to which the received signal is associated. The method may further comprise conveying the received signal to the identified one of the wireless charging module and the near-field communication module.

Aspects disclosed herein relate to providing peer mode passive communications while accounting for a power level available to operate a NFC device. In the disclosed aspects, a near field communication (NFC) device may be equipped to detect a value for a power level available to operate the NFC device. The NFC device may be further equipped to determine a first duration to allocate for a listening mode and a second duration to allocate for a polling mode based at least in part on the determined available power level value and select a RF discovery loop based on the determined first duration and second duration. The NFC device may be further operable to perform peer mode discovery using the selected RF discovery loop.
