Abstract: Provided is a method for feeding back different uplink-downlink configuration ratios for LTE-A TDD. For an asymmetric uplink and downlink sub-frame in a carrier aggregation scenario, the uplink sub-frame of each component carrier only feeds back Ack/Nack of the downlink sub-frame PDSCH of the current carrier, not feeding back Ack/Nack of other carriers. Also proposed is another method for feeding back different uplink-downlink configuration ratios for LTE-A TDD. For an asymmetric uplink and downlink sub-frame in a carrier aggregation scenario, Ack/Nack of the downlink sub-frame of each component carrier is fed back by the uplink sub-frame of the closest auxiliary cell with the minimum auxiliary cell index value after at least four sub-frames, allowing Ack/Nack of a plurality of carriers to be transmitted on other carriers.

Abstract: A device integrated with payment function and collection function, includes a smart memory card and an intelligent terminal. The intelligent terminal is adapted to generate a secure transaction management instruction, send the secure transaction management instruction to the smart memory card and notify an execution result of the secure transaction management instruction; to interact with a bank side system via a remote communication network; to interact with user via a user interface; to interact with another device in near field communication mode; to process transaction instruction, generate a secure transaction application instruction and send the secure transaction application instruction to the smart memory card; and to notify an execution result of the secure transaction application instruction. The smart memory card is adapted to execute the safe transaction management instruction and the safe transaction application instruction.

Abstract: A radio frequency identification device includes: a radio frequency interface, a core control unit and a universal storage interface; the core control unit is adapted to receive radio frequency identification instruction from another radio frequency identification device within predetermined range or portable terminal apparatus through the universal storage interface or the radio frequency interface, to perform corresponding radio frequency identification processing according to the radio frequency identification instruction and the current operation status of the devices, and to switch the operation status of the device when the instruction is operation status switching instruction; the radio frequency interface is adapted to realize information interaction between the core control unit and the another radio frequency identification devices within predetermined range; the universal storage interface is adapted to realize information interaction between the portable terminal apparatus and the core control uni
