TECHNIQUES FOR COMMUNICATION WITH TAG DEVICES
First Claim
1. An apparatus to communicate with tag devices via near field communications (NFC) comprising:
- a processor component;
a timing component for execution by the processor component to determine an amount of time remaining in a current sleep pause between two consecutive transmissions of a Tag-Talks-First (TTF) tag device; and
a communications component for execution by the processor component to determine whether the amount of time remaining in the current sleep pause is sufficient to transmit a request for response to a Response-Request (RR) tag device and receive a response to the request from the RR tag device, and to transmit the request based on the amount of time remaining in the current sleep pause.

Abstract
Various embodiments are generally directed to techniques for resolving interference in near field communications (NFC) among multiple NFC tag devices communicating with a reading device in which one of the tag devices employs a Tag-Talks-First (TTF) protocol while the others use a Request-Response (RR) protocol. An apparatus to communicate with tag devices via near NFC includes a timing component to determine an amount of time remaining in a current sleep pause between two consecutive transmissions of a TTF tag device; and a communications component to determine whether the amount of time remaining in the current sleep pause is sufficient to transmit a request for response to a RR tag device and receive a response to the request from the RR tag device, and to transmit the request based on the amount of time remaining in the current sleep pause. Other embodiments are described and claimed.

8. An apparatus to communicate with tag devices via near field communications (NFC) comprising:
-
an antenna; a processor component; an interface coupling the processor component to the antenna to enable NFC; a power transmission component for execution by the processor component to operate the interface to generate an electromagnetic field in a vicinity of the antenna to wirelessly provide electric power to at least one of a Tag-Talks-First {TTF} tag device or a Response-Request (RR) tag device; a timing component for execution by the processor component to determine when a sleep pause between two consecutive transmissions of the TTF tag device begins; and a RR detection component to transmit a request for response when the sleep pause begins to detect the RR tag device. - View Dependent Claims (9, 10, 11, 12)
