RANGE EXTENSION OF RADIO FREQUENCY IDENTIFICATION DEVICES
20240103120 · 2024-03-28 ·

Embodiments of the present disclosure utilize signals generated by a radio frequency identification (RFID) antenna to locate the antenna. For example, a signal emitted by a transmitter can cause an unpowered mobile device's RFID antenna to generate return signals that are received by multiple antennas. Time difference of arrival (TDOA) and a frequency difference of arrival (FDOA) values can be calculated for the received signals. The calculated TDOA and FDOA values can be correlated using a cross ambiguity function (CAF). The correlated values can be plotted on a map to create a set of correlation maps. The correlation maps can be combined to produce an average map and the antenna can be located by identifying a maximum correlation value on the average map.

Signal transmission method and apparatus

A signal transmission method and an apparatus. The method includes: a location management device receives first SRS resource configuration information from a serving cell and/or a neighboring cell. The location management device sends second SRS resource configuration information to a terminal device, where the second SRS resource configuration information includes third SRS resource configuration information and a downlink reference signal associated with an SRS resource indicated by the third SRS resource configuration information, and the third SRS resource configuration information is a part or all of the first SRS resource configuration information. The location management device configures the SRS resource for the terminal device, so that the SRS resource can be associated with the downlink reference signal. This helps the terminal device obtain information about a transmission beam for sending an SRS, and therefore SRS receiving efficiency of the cell can be improved to some extent.
