  • Publication number: 20200387874
    Abstract: Disclosed in the present invention is a multi-operator direct payment system of a public operating service platform for electric vehicles, which belongs to the technical field of electric vehicle operation. The multi-operator direct payment refers to a payment method for the operators where the platform is hosted for the multiple operators. The multi-operator direct payment allows the payment to be directly paid to the actual charging account of the operators through dynamically-targeted payment techniques, without the need for secondary clearing and settlement, which also improves the timeliness of fund arrival, further achieves and promotes the interconnection among the multiple operators. In the traditional operating mode, the money firstly arrives at the platform and is then transferred to the operators, causing the problems of slow fund arrival, extra fees for transfer, and being not subject to the operators' control.

  • Publication number: 20200221451
    Abstract: The present disclosure relates to a terminal device, in which a processing module selects one or more normal carriers or special carriers from a first carrier set for an uplink subframe, where the first carrier set includes all carriers in carrier aggregation that are used by the terminal device to send a first uplink subframe; and a sending module cancels sending of the uplink subframe on one or more carriers, where the special carrier is a carrier on which the terminal device sends neither uplink data nor uplink control information in uplink, and the normal carrier is a carrier that is used by the terminal device to send uplink data and/or uplink control information. An uplink subframe on some carriers is rejected, thereby resolving a problem that information such as a downlink channel characteristic of a carrier cannot be obtained when no uplink reference signal is sent on the carrier.
