摘要： Embodiments of the present application provide a wireless communication method and device. A network device may send a preamble signal before a downlink signal is sent, so as to assist a terminal device to perform downlink signal detection. The terminal device receives the downlink signal after detecting the preamble signal, thereby avoiding the problem that the complexity and the power consumption are increased because the terminal device needs to perform blind detection on the downlink signal. The method comprises: performing channel detection on a carrier of an unlicensed frequency band; and in the case of the channel detection being successful, sending a preamble signal on the carrier from a first moment, the preamble signal being used for determining that the carrier can be used for transmitting a downlink signal.

摘要： Disclosed in the present invention are a system information transmission method and apparatus. The method comprises: a terminal requesting system information of a first network side device by means of a dedicated control signal, the system information being system information that the terminal needs to use; and the terminal receiving the system information. In the embodiments of the present invention, a terminal is capable of requesting system information of a network side device by means of a dedicated control signal on the basis of requirements of the terminal, so as to save transmission resources used when transmitting the system information, thereby avoiding waste of transmission resources present in prior art, which is due to a base station transmitting system information by means of a broadcast mode.

摘要： Disclosed are a method, a terminal, and a base station for use in data transmission. The present invention allows the terminal to receive a downlink control signaling at a low frequency band and to transmit data at a high frequency band when high-speed data transmission is required. The method comprises: when there is no data transmission, the terminal receives first indication information in a first cell using a first frequency band, the first indication information being used for indicating a terminal having received the first indication information to use a second frequency band for data transmission; the terminal transmits data in a second cell using the second frequency band on the basis of the first indication information when data transmission is required.

摘要： Provided in embodiments of the present application are a data transmission method, a terminal device and a network device, through which uplink data transmission can be performed when the channel detection bandwidth is inconsistent with the carrier bandwidth or the data transmission bandwidth of the system, thereby improving utilization efficiency for frequency spectrum resources of an unlicensed frequency spectrum. The method includes: receiving, by a terminal device, scheduling information transmitted by a network device, where the scheduling information is used to schedule the terminal device to transmit, through first time-frequency resources on a first carrier, a first transport block, where the first transport block is a transport block carried by a physical channel; performing, by the terminal device, rate matching on the first transport block to obtain first data; determining, by the terminal device, an uplink transmission mode, where the uplink transmission mode includes: a first transmission mode and a second transmission mode, where the first transmission mode is that the first data is transmitted through all or part of resources occupied by the first time-frequency resources on a frequency domain, and the second transmission mode is that the first data is transmitted through all resources occupied by the first time-frequency resources on a frequency domain and is not transmitted through part of resources occupied by the first time-frequency resources on a frequency domain; and performing, by the terminal device, channel detection on the first carrier, and transmitting, according to a detection result and the uplink transmission mode, the first data to the network device through the first time-frequency resources.
