Methods and apparatus for improving NFC RF discovery based on detection of other RF activity

摘要

Aspects disclosed herein relate to improving NFC RF discovery through monitoring RF activity associated with one or more RATs. In one example, a first NFC device may be configured to use both a first RAT and NFC. The first NFC device may monitor RF activity on a first RAT to determine whether there is at least a greater probability that a second NFC device is within a threshold. The NFC device may be also configured to modify at least an interval between polling modes in a NFC RF discovery loop based on the determination.

1. A method of communications, comprising:
monitoring a signal strength value of a first radio access technology (RAT) used by a first near field communication (NFC) device, wherein the first RAT is different than a NFC radio frequency (RF) technology used by the first NFC device; determining an increase the monitored signal strength value of the first RAT by the NFC device; determining that a probability that a second NFC device is within a threshold distance of the first NFC device has increased based at least on the monitored signal strength value of the first RAT and the increase in the monitored signal strength value of the first RAT, wherein the threshold distance is based on a coverage area of the NFC RF technology used by the first NFC device; and modifying at least an interval between polling modes in a NFC RF discovery loop based on the determination that the probability that the second NFC device is within the threshold distance of the first NFC device has increased.
