Abstract: A detection method includes determining a first frequency point of N frequency points, transmitting a radio signal in a first frequency band in N frequency bands. One of the N frequency bands partially overlaps at least one frequency band in other N−1 frequency bands, and an absolute value of a difference between lowest frequencies of any two frequency bands of the N frequency bands is not less than a first threshold (F), or the N frequency bands have at least one second frequency band that partially overlaps the first frequency band, and an absolute value of a difference between a lowest frequency of each second frequency band and a lowest frequency of the first frequency band is not less than F.

Abstract: The present disclosure relates to the mobile communications field, and in particular, to a transmission resource determining technology in a wireless communications system. In a data transmission method, a network device determines a transmission resource used for data transmission, and performs data transmission with a terminal device on the determined transmission resource. A time domain resource occupied by the transmission resource in a time domain is one of N types of time domain resources, and a time length of any type of time domain resource in the N types of time domain resources is less than 1 ms. According to this method, a data transmission latency can be effectively reduced, thereby meeting a requirement for a low-latency service.

Abstract: A downlink control information (DCI) sending method and an apparatus are provided. A base station determines a first channel resource, where the first channel resource is located in the ith time unit of a subframe in a time domain, the subframe includes NT time units, NT is an integer greater than or equal to 2, and i is a positive integer less than or equal to NT; and the base station sends DCI to a terminal device on the first channel resource. In this solution, the first channel resource that carries the DCI is located in the ith time unit of the subframe in the time domain, where i is a positive integer less than or equal to NT. That is, there is a first channel resource in each time unit of the subframe.

Abstract: A transmission control method includes steps for obtaining interference information of a first radar on a first frequency band, for example, through listening before transmission. The interference information represents a degree to which the first radar is interfered with on the first frequency band. Transmission duration of the first radar on the first frequency band is determined based on the interference information, where the interference information indicates either a difference between the transmission duration and an initial transmission duration of the first radar, or the transmission duration.

Abstract: A signal transmission method includes a radar detection apparatus selecting a transmit frequency band from a predefined or pre-specified first frequency band. The first frequency band is pre-divided into M sub-frequency bands, and the transmit frequency band includes N sub-frequency bands in the M sub-frequency bands, where a bandwidth of the transmit frequency band is greater than or equal to an operating bandwidth of the radar detection apparatus. A sum of bandwidths of any N−1 sub-frequency bands in the N sub-frequency bands is less than the operating bandwidth of the radar detection apparatus. In addition, a minimum quantity of sub-frequency bands is used to transmit a signal.

Abstract: Embodiments of the present disclosure provide a data communication method, a terminal device, and a network device. In the solution, a terminal device receives first indication information in a first time period; and the terminal device transmits first information in a second time period, where a duration of the first time period is a first time unit, a duration of the second time period is a second time unit, and a duration of the second time unit is greater than a duration of the first time unit. In this way, although the terminal device receives the first indication information in a first time unit N, the terminal device transmits the first information in a second time unit M whose duration is greater than that of the first time unit.

Abstract: A method related to processing interference between cooperative radars, where a radar obtains configuration information used to indicate a ratio of a quantity of first data update periods to a quantity of second data update periods in a sending period. The first data update period is used to send a first radio signal, and the second data update period is used to send a second radio signal. Waveform configurations of the first radio signal and the second radio signal are different, to effectively reduce mutual interference between the first radio signal and the second radio signal.
