An automatic retransmission request control system in OFDM-MIMO communication system. In this system, an ACK/NACK output part (320) of a receiver transmits, to a transmitter, a feedback information of positive or negative response based on the result of a cyclic redundancy check. An error data stream decision part (310) of the transmitter determines, based on the feedback information, a data stream that need be retransmitted, and a retransmission mode selection part (312) selects a retransmission mode from among (a) a mode in which to transmit the data, which are to be retransmitted, via the same antenna as in the previous transmission, while transmitting, at the same time, new data by use of an antenna via which no data retransmission is requested; (b) a mode in which to transmit the data, which are to be retransmitted, via an antenna via which no retransmission is requested, while transmitting new data via another antenna at the same time; (c) a mode in which to use STBC to retransmit the data via an antenna via which no retransmission is requested; and (d) a mode in which to use STBC to retransmit the data via all the available antennas.

In one embodiment of the invention, service providers generate bloom filters with the user ID codes of registered users and exchange the bloom filters with one another. In response to a request to locate a first user, a first service provider will query its own registration database to determine if the first user is registered with the first service provider. If the first user is not registered with the first service provider, then the first service provider will query its bloom filters to identify other service providers with which the first user may be registered. A positive response from a bloom filter indicates that the first user may or may not be registered with the service provider associated with that bloom filter, and a negative response indicates with certainty that the first user is not registered with the service provider associated with that bloom filter.

Techniques for product authentication are disclosed which employ both identification tags affixed to products and a central server to validate scanned tag codes. To verify authenticity of a product, a user may peel off a cover label from the identification tag to reveal a scannable or readable code/symbol, use a device to scan or read the code/symbol, and then transmit it to the central server for authentication. The central server determines, based on database records, whether the code/symbol is genuine and never scanned by another device before. If so, the product is deemed authentic, and a corresponding token is created and stored based on the unique combination of the code/symbol and an identifier of the device used to scan/submit the code/symbol. Any subsequent authentication request originating from a different device to the central server with the same code/symbol may receive a negative response about the authenticity of the underlying product.

The invention provides a data transmission method which comprises the following steps: step 1, a connection is established between a transmitting terminal and a receiving terminal and each terminal is set in opened state, the transmitting terminal merges or splits short messages to form data packets and sends the data packets sequentially to the receiving terminal; step 2, the receiving terminal receives the data packets and then checks, and feedbacks a negative response message indicative of the data pack loss to the transmitting terminal when detecting the loss of a certain data pack; step 3, the transmitting terminal resend the lost data pack to the receiving terminal based on the negative response message, the receiving terminal receives the data followed by unpacking or packing. With the method, the transmitting terminal can instantly detect the message sequence that doesn't arrive at the receiving terminal, and retransmit the lost data pack in time, thereby reducing the time delay of the lost message.

The invention relates to an industrial wireless sensor network communication method based on relay nodes, belonging to the field of sensor network communication. A network management center distributes a preferred communication path resource according to the request of a source node and current network state information, selects a relay node and a relay path according to constraint conditions, and distributes the communication resources of the relay path. In the communication process, when the relay node receives the negative response from the node of the last hop, the probability that the transmission delay exceeds a threshold is reduced, the frequency of retransmission initiated by the source node is reduced, and the energy consumption for retransmitting data is reduced. Meanwhile, the relay node also dynamically changes the priority of data packets, avoids delaying transmission of the data packets again, and ensures that the data packets reach a destination node in delay requirements. By adopting collaboration among the relay node, the destination node and the network management center, the packet loss rate is reduced, the frequency of retransmission initiated by the source node is reduced, and the energy consumption for retransmitting data is reduced.

This invention discloses a method to avoid repeatedly sending automatically resending data. When UE conducts switching and source base station transmits data to the target one, UE or source base station also need to provide the data receiving state and / or paragraphing information of UE. According to it, the target base station determines whether the state of receiving paragraphing data is right, and only resends those data that gets negative response of UE, which is not correctly received by UE, and sends data never transmitted, avoiding resending the received data and saving resources effectively.

A method and apparatus for automating the process of confidentially determining whether individuals in social groups have positive or negative responses to each other and for automating the process of notifying the people involved of such responses. A computer system receives inputs from participants who have engaged in a group social event indicating the positive and negative responses they have toward each other. The system collects this information and searches for matches, i.e., for mutual positive responses, and for other patterns of response that provide valuable feedback to the participants, such as which participant received the most positive responses overall. The system then reveals this information to all the participants, and allows the participants who matched with each other to communicate privately.
