  • Patent number: 11975593
    Abstract: A heat pump system, a heat management method and a vehicle are provided. The heat pump system includes an integrated heat exchanger integrated with a superconducting liquid flow passage and a refrigerant flow passage. The refrigerant flow passage is provided inside an on-board refrigerant circulation loop and is used for cooling and/or heating to adjust the temperature within a passenger compartment of a vehicle. The superconducting liquid flow passage is in communication with a motor heat dissipating conduit, for absorbing the heat generated by an on board motor and transferring the heat to the integrated heat exchanger by means of phase change heat transfer. The heat pump system can increase the energy utilization rate for the vehicle and reduce the allowable ambient temperature of the heat pump system.

  • Patent number: 10298368
    Abstract: The present invention discloses a method, includes: managing a first cell, obtaining resource scheduling information of a neighboring cell of the first cell in a first time interval, and determining an interference level of inter-cell interference of the first cell according to the obtained resource scheduling information; and measuring an inter-cell interference value of the first cell in a second time interval, and storing the measured inter-cell interference value of the first cell in the second time interval by using the interference level as an index, where the interference level is determined according to the resource scheduling information in the first time interval. Based on a stored correlation between an interference level and a real inter-cell interference value obtained by means of measurement, the first base station can quickly and accurately predict a future inter-cell interference value by determining an interference level of inter-cell interference.

  • Patent number: 8599810
    Abstract: A method, equipment and system for implementing coordinated multi-point transmission are provided for resolving the problem that there exists phase noise in the signals received by a User Equipment (UE) end in coordinated multi-point transmission. The method for implementing coordinated multi-point transmission includes: obtaining phase differences between the current service cell and other coordinated cells by calculating channel cross-covariance matrixes between the current service cell and other coordinated cells in a coordinated multi-point transmission system (101); feeding back the phase differences corresponding to the base stations of said other coordinated cells respectively to the base stations of said other coordinated cells, in order to implement phase compensation (102); receiving the signals transmitted after the phase compensation by base stations of all the coordinated cells (103).
