Abstract
A data transmission/reception method in Near Field Communications (NFC) for enhancing data throughput between at least an initiator device and a target device. The data transmission/reception method typically includes initiating a communication between an initiator and a target that perform NFC, aggregating a plurality of data packet units to be transmitted in order to form an aggregated frame, and transmitting the aggregated frame to a counterpart NFC device.
Claims38
A data transmission/reception method in Near Field Communications (NFC), the method comprising:
- (a) initiating a communication between an initiator and a target that perform NFC;
- (b) aggregating a plurality of data packet units for transmission to form an aggregated frame;
- and
- (c) transmitting the aggregated frame to one of the target and the initiator,
- wherein the aggregated frame comprises an identifier of a frame type indicating whether a data frame included in the aggregated frame comprises an Aggregated Information (AI) frame or an Aggregated Unnumbered Information (AUI) frame,
- wherein the AI frame comprises a data information field that includes a plurality of sequence numbers associated with transmission of the plurality of data packets and reception thereof and the plurality of aggregated data packets, and the AUI frame comprises a data information field that includes the plurality of aggregated data packets without the plurality of sequence numbers associated with transmission of the plurality of data packets and reception thereof.
A data transmission/reception method in Near Field Communications (NFC), the method comprising:
- initiating a communication between an initiator and a target device via the NFC;
- aggregating a plurality of data packet units for transmission to form an aggregated frame;
- and
- transmitting the aggregated frame to the target device or the initiator without relying on a connection setup procedure,
- wherein the aggregated frame comprises a frame type identifier indicating that the plurality of data packet units included in the aggregated frame are aggregated,
- wherein the aggregated frame is an aggregated unnumbered information (AUI) frame, and the AUI frame comprises a data payload that includes the plurality of aggregated data packet units without a plurality of sequence numbers associated with transmission of the plurality of data packet units and reception thereof, and
- wherein the aggregating includes placing each of a plurality of length information fields respectively in front of each of the plurality of data packet units, the number of length information fields is the same as the number of data packet units, and each of the length information fields alternates with each of the packet data units.
