Abstract: A wireless communication method includes obtaining an uplink signal, obtaining a first transmission parameter and a second transmission parameter of the uplink signal based on the uplink signal and transmission data carried in the uplink signal, determining a target transmission device based on the second transmission parameter, selecting a first transmission sub-parameter associated with the target transmission device in the first transmission parameter, selecting a second transmission sub-parameter associated with the target transmission device in the second transmission parameter, and determining a third transmission parameter of the uplink signal based on the first transmission sub-parameter and the second transmission sub-parameter.

Abstract: An information processing method includes receiving power headroom report (PHR) information of a user terminal, and in response to determining that the PH information satisfies a target condition, sending a state switch message used to switch an operation state of the user terminal to the user terminal. The PHR information carries power headroom (PH) information of the user terminal. The state switch message is used to instruct the user terminal to switch from a first power consumption operation state to a second power consumption operation state. Power consumption of the first power consumption operation state is greater than power consumption of the second power consumption operation state.

Abstract: This disclosure relates to a smart wearable device and a contactless payment method, said smart wearable device comprising: an information storage unit, a control unit and a wireless communication unit, wherein, the information storage unit is used for storing information of one or more bank cards; the control unit is used for identifying gathering means based on information of the gathering means received by the wireless communication unit, reading bank card information from the information storage unit, and controlling the wireless communication unit to transmit the read bank card information to the gathering means for payment.
