Patent number: 10809412Abstract: A WEM-based method for deep resource detection using sky waves refers to the technical field of deep resource detection. The proposed method of deep detection using sky waves improves the traditional “atmospheric-lithosphere” half-space propagation theory into a full-space “sky wave” theory of “ionosphere-atmosphere-rock layer”, that is, the influence of the ionosphere and the displacement current in the air are taken into consideration to obtain a new precise expression of “sky wave” response, which is suitable for full space, slow attenuation and long distance propagation. A receiving device for sky wave signal has been developed. Through theoretical model calculation and actual data measurement, it is known that it is possible to use the sky wave for detection within the scope of China's national territory to realize the high-precision electrical structural exploration within a depth of 10 kilometers and open a new era of artificial source electromagnetic detection.Type: GrantFiled: December 22, 2017Date of Patent: October 20, 2020Assignee: Institute of Geology and Geophysics, Chinese Academy of SciencesInventors: Qingyun Di, Guoqiang Xue, Ruo Wang, Zhiguo An, Changmin Fu, Da Lei, Xianjun Zhuo, Zhongxing Wang

Patent number: 9338699Abstract: The present solution enables a packet switched connection to be temporarily released at the wireless terminal for supporting voice calls over a Circuit-Switched (CS) Fallback. The packet switched connection of the LTE core network retained for a pre-defined period of time during the CSFB session allowing the user to quickly switch back to the packet switched connection when the CSFB session is shorter than the predefined period or when the voice call CSFB attempt fails. This is accomplished by the introduction of a timed buffer to control the length of time the LTE core network connection and wireless context information will be retained.Type: GrantFiled: December 16, 2013Date of Patent: May 10, 2016Assignee: Telefonaktiebolaget LM Ericsson (Publ)Inventors: Weigang Li, Indranil Tapadar, Guoqiang Xue

Patent number: 8787340Abstract: A method of connection setup in mobile wireless data communications systems is disclosed where the connection setup time is decreased for delay-sensitive communications sessions relative to the normal connection setup time for confidence-dependent communications sessions. This is achieved by performing some of the connection set-up steps for delay-sensitive communications sessions after successfully demodulating a smaller number of indications identifying an access terminal's desired serving resource than would be demodulated in the case of a confidence-dependent communication session prior to performing the same connection set-up steps.Type: GrantFiled: February 2, 2012Date of Patent: July 22, 2014Assignee: Ericsson ABInventors: Xixian Chen, Vasanta Chivukula, Weigang Li, Guoqiang Xue, Ryan Santa, Miroslav Budic, Brian Troup, Martin Kendall

Patent number: 7505534Abstract: This invention enables determining whether a received frame is an erasure, a DTX mode frame or a CONT mode frame, using a metric m derived from the log likelihood ratio (LLR). The new metric is obtained by calculating the mean for the LLRs for a frame; a threshold T for this metric is also established. A received frame is declared a CONT frame if the CRC value indicates a successfully recovered frame, and m>T. A received frame is a DTX frame if m<T. Finally, a frame is declared an erasure if the CRC value indicates a failed frame, and m>T. The mean absolute LLR may also be used for determining the transmission rate of the system. In this case, a voice frame is decoded for all rates available; the transmission rate is that which corresponds to a passed CRC and has the highest m.Type: GrantFiled: October 23, 2003Date of Patent: March 17, 2009Assignee: Nortel Networks LimitedInventors: Guoqiang Xue, Xixlan Chen

Patent number: 7480516Abstract: A cellular wireless communication system includes base transceiver stations and mobile stations that operate with a closed loop power control. The mobile tracking is performed based on the lock in and lock out thresholds by the base transceiver stations. A forward link power control bit is decoded from the reverse channel. An additional threshold is introduced for determining at the base transceiver station whether the decoded forward link power control bit is valid or invalid. The finger energies obtained from a finger processor formed by a RAKE receiver of the base transceiver station are compared to the additional validation threshold. The additional validation threshold is independent of the tracking thresholds and usually greater than them. The validation performance may not be affected by low signal/noise. The forward link traffic channel gain of the base transceiver station is controlled in response to the invalidity of the decoded forward power control bit.Type: GrantFiled: October 28, 2004Date of Patent: January 20, 2009Assignee: Nortel Networks LimitedInventors: Xixian Chen, Guoqiang Xue, Mark Harris, Weigang Li
