摘要： The RFID system includes an RFID reader for sending information selected from among collision type information, idle type information, and readable type information, to all of the RFID tags depending on the number of signals in the corresponding time slot, and RFID tags for performing functions, in which, when information, indicating that a current time slot is a collision type, is fed back from the RFID reader, each of RFID tags selects one arbitrary value of either 0 or 1 and is assigned a time slot, in which a corresponding RFID tag will send a signal to the RFID reader, based on the selected value, a single tag group that caused a collision is divided into two sub-groups depending on the assigned time slots, and tags of the sub-groups send signals, including IDs thereof, to the RFID reader in different time slots for the respective sub-groups.

摘要： The present invention relates to a tag anti-collision Radio Frequency Identification (RFID) system and a method for tag identification. The method for tag identification consists of a first step of initializing a queue (Q) field and storing a prefix of a candidate queue (CQ) field in the queue field; a second step of transmitting a query including the prefix stored in the queue field to the RFID tags, and deleting the transmitted prefix from the queue field; a third step of inserting a prefix, in which prefixes 0 and 1 are inserted into a rear portion of a prefix of a previously transmitted query, into the queue field if two or more tags respond to the previously transmitted prefix and, therefore, the tags cannot be identified, and inserting the prefix of the previously transmitted query into the candidate queue field and deleting an unnecessary prefix stored in the candidate queue if there is no response or only one tag responds with respect to the previously transmitted prefix; and a fourth step of determining whether a prefix stored in the queue field exists, and returning to the second step if there is a prefix stored in the queue field.

摘要： A communication apparatus and a communication method in a wireless communication network are disclosed. A frame-transmitting/receiving unit transmits a frame to another terminal of the wireless communication network or receives a frame another terminal. A transmission rate-measuring unit measures the transmission rate used in a transmission channel of a transmission terminal which transmits a frame to a receiving terminal, the destination of the frame to be transmitted, the transmission rate used in the transmission channel of the receiving terminal, and the transmission rate used in the transmission channel between the transmission terminal and the receiving terminal. A relay target terminal determination unit calculates a first transmission delay in the event data is directly transmitted from the transmission terminal to the receiving terminal on the basis of the measured transmission rate and a second transmission delay in the event data is transmitted from the transmission terminal to the receiving terminal when a relay transmission is performed by a cooperation communication, and determines the transmission terminal as a relay target terminal for providing the cooperation communication if the second transmission delay is smaller than the first transmission delay. A relay control unit enables the identification number of the relay target terminal to be included in a first data frame transmitted to the receiving terminal by the frame-transmitting/receiving unit, enables a relay frame which indicates the start of the cooperation communication to be transmitted to the receiving terminal when a request frame indicating the use of the cooperation communication is received from the relay target terminal, and enables a second data frame transmitted from the relay target terminal to be transmitted to the receiving terminal when a response frame indicating that the cooperation communication is enabled is received from the receiving terminal. The present invention reduces overhead caused by the cooperation communication.
