摘要： A method for synchronizing overlapping cells covered by different base stations include obtaining a propagation delay between a first base station and a second base station, scheduling by the f I rst base station a selected one of first users located in a first cell covered by the first base station to transmit a first data packet which is a part of a transmission data frame, transmitting at the selected one the first users a transmission offset indicating the difference in a time domain between the beginning of the transmission data frame and the first data packet, in response to the reception of the first data packet, recording a reception offset at a selected one of second users located in a second cell covered by the second base station, the reception offset indicating the difference in time domain between the beginning of a reception data frame and the first data packet, transmitting at the selected one of the second users the reception offset to the second base station, calculating at the second base station a frame slide by adding the transmission offset and the propagation delay, and subtracting the reception offset, and synchronizing the first cell and the second cell based upon the calculated frame slide.

摘要： A system and method for determining the network timing of a communications network from a mobile station that receives signals from a plurality of base stations. An estimated location of a mobile station may be determined through any number of or combination of location technologies. Network measurements such as observed time difference values and/or a round trip time values at the mobile station or base stations in the network may be utilized. Network timing relationships may be determined as a function of the estimated location and network measurements. An estimated location of a second mobile station may be determined as a function of the network timing relationships.

摘要： Embodiments of the present invention disclose a wireless data transmission method, including: obtaining a repetition quantity required for data transmission of each user equipment in a management range, and determining a round trip time RTT of the user equipment according to obtained repetition quantity information of the user equipment, process quantity information of the user equipment, and a transmission time interval TTI. Because in the embodiments of the present invention, an RTT may be set according to a requirement, a length of the RTT may be adjusted in a range allowed by a delay. In addition, a repetition quantity required by a user equipment may be learned of by using repetition quantity information of the user equipment . Therefore, for a coverage capability of each user equipment , each RTT can include as few processes as possible, provided that a requirement of the user equipment for a repetition quantity is met. In this way, a probability of successful data decoding may be efficiently improved, thereby efficiently improving a coverage capability of user equipment in wireless communication.

摘要： A signal system synchronization for telecommunication networks comprises a reference signal source providing a reference signal to one or more master devices arranged and configured for two-way satellite communication and transmitting through said satellite said reference signal to a number of slave devices. Said slave device are arranged and configured for one-way only satellite communication and provided with information about its position, position of said master device and satellite position; advantageously each slave device locally regenerates the received satellite signal on the basis of propagation delay between master and slave devices and relative delay occurring between satellite to master device signal and satellite to slave device signal. The regenerated received signal is therefore synchronous with said reference signal.
