Abstract: The method of the present invention includes: obtaining an original signal outputted by a SIM card; converting the original signal into a target signal, where under an equal transmission condition and/or at an equal transmission distance, signal attenuation and/or distortion of the target signal are/is less than signal attenuation and/or distortion of the original signal; and sending the target signal to a terminal device, where the terminal device obtains the target signal by using a signal transmission line, and the SIM card exists independent of the terminal device. In the present invention, a SIM card may be separated from a terminal device, and a generated target signal may be transmitted over a relatively long distance by using a signal transmission line, which can satisfy an application that requires a SIM card to be placed far away from a terminal device.

Abstract: The application pertains to a method for communicating a downlink control signal. A base station maps a physical downlink control channel (PDCCH) sequentially to resource elements for transmitting the PDCCH in each orthogonal frequency division multiplexing (OFDM) symbol according to an order of OFDM symbols used by the PDCCH of a user equipment (UE). The PDCCH is sent to the UE from the base station by using the resource elements. Because the PDCCH is mapped sequentially to resource elements for transmitting the PDCCH in each OFDM symbol according to an order of OFDM symbols used by the PDCCH of the UE, different control channel elements of PDCCHs at different aggregation levels will not include a same PDCCH modulation symbol, thereby ensuring that the UE judges a start position of the PDCCH correctly.

Abstract: The present application discloses a method for interconnection between a terminal device and a gateway device. When the terminal device detects that the terminal device and the gateway device meet a first connection condition and that it is the first time the terminal device is to be connected to the gateway device, acquiring, from the gateway device, a first common SSID preset in the gateway device; and when authentication performed by the terminal device on the acquired first common SSID succeeds, sending a second common SSID preset in the terminal device to the gateway device, so that when authentication performed by the gateway device on the second common SSID succeeds, a common SSID-based connection is established between the terminal device and the gateway device. So using the method, processing of interconnection between a terminal device and a gateway device takes a short time and a process is relatively simple.
