  • Patent number: 10879968
    Abstract: Embodiments of the present application provide a data processing method. In the data processing method, before channel coding, a transmission control device divides a data flow into N sub-data flows, allocates the N sub-data flows to N transmit ends, and notifies the N transmit ends of a same time-frequency resource used for sending the allocated sub-data flows. By applying the technical solution, the N transmit ends can send different sub-data flows of a same data flow to a same receive end on the same time-frequency resource without a large amount of signaling interworking, and a system throughput can be improved without increasing network implementation complexity.

  • Patent number: 10721047
    Abstract: In certain embodiments, a method includes generating a first signal and a second signal. The first signal includes at least one first sub-signal, and the second signal includes at least one second sub-signal. A subcarrier frequency spacing of the first sub-signal is M times as large as a subcarrier frequency spacing of the second sub-signal. The method further includes separately sending each first sub-signal and each second sub-signal. In a range of a first preset frequency apart from a reference subcarrier frequency, all the second sub-signals sent on a subcarrier corresponding to a subcarrier frequency whose difference from the reference subcarrier frequency is a non-integer multiple of the subcarrier frequency spacing of the first signal are zero signals. The reference subcarrier frequency is a subcarrier frequency of the first sub-signal adjacent to the second signal in a frequency domain.

  • Patent number: 7373155
    Abstract: The present invention relates to a method for positioning a mobile station and a repeater thereof. Said method comprises: the mobile communication network, when receiving a positioning request from a mobile station, instructing repeaters to send auxiliary positioning signals, and the mobile station performs measurement according to the received auxiliary positioning signals sent from the repeaters and downlink signals sent from the base station, and then estimating the position of the mobile station according to the measurement results, and thereby implementing the positioning of the mobile station. Said repeater is implemented through adding an auxiliary positioning unit in the downlink processing channel of a traditional repeater; said auxiliary positioning unit comprises a communication module, a frame timing recovery module, a timing control module, and a pilot modulating module.

  • Patent number: 7065369
    Abstract: The invention discloses a method of locating and measuring a mobile station, which relates with the radio locating technique in mobile communication field. Comparing with the conventional radio locating technique, the method improves the first path determination method of a neighbor base station downlink signal as follows: with geometrical relationship such as the distance between a MS to the reference base station and the distance between a neighbor base station to the reference base station, an effective range of the downlink signal first path of the neighbor base station can be calculated; the effective range is an effective search window that is shorter than the original large search window, and the first path determination of the neighbor base station downlink signal is made within the effective search window. The invention raises the first path determination accuracy of a neighbor base station downlink signal, so the mobile station locating accuracy is raised too.
