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: A laser includes a substrate and a resonant cavity. In addition to an active gain region, a first phase shift region, an optical branching region, and N reflective mode selection regions, the resonant cavity further includes a highly reflective surface, where a reflectivity of the highly reflective surface is greater than reflectivities of the N reflective mode selection regions, so that laser beams are output from the N reflective mode selection regions. Because the laser naturally includes at least two reflective mode selection regions, at least two laser beams are output. According to the laser provided by the embodiments of the present invention, one laser can output two laser beams or even multiple laser beams; therefore, laser beam generation efficiency is high and average costs for generating a single laser beam are accordingly reduced.

Abstract: The present invention discloses a multi-standard network convergence method, device, and system and relates to the field of communications technologies. The method includes: acquiring an AC mapping parameter corresponding to an RLC packet; performing encapsulation on the AC mapping parameter and the RLC packet; and forwarding an encapsulated packet to a second network, so that the second network acquires a corresponding AC according to the AC mapping parameter in the encapsulated packet, and places the RLC packet into a transmission queue corresponding to the AC for transmission. According to the present invention, an AC mapping parameter and an RLC packet are encapsulated and then sent to a second network, so that the second network may determine a corresponding AC according to the AC mapping parameter, so as to accurately place the RLC packet into a corresponding transmission queue for transmission and further implement multi-standard network convergence.

Abstract: A communication method and a related apparatus are disclosed, and are applied to the field of communication technologies. In embodiments of this application, when switching a frequency number, a first node notifies, by using physical layer control signaling indicating frequency number switching, a second node of operating frequency number switching, where the physical layer control signaling indicating frequency number switching is scrambled by using a first identifier to distinguish the physical layer control signaling from physical layer signaling of another function. In the foregoing implementation, an indication of operating frequency number switching is completed by using the first identifier and the physical layer control signaling. This shortens duration of frequency number switching, so that the first node and the second node can switch to a second frequency number as soon as possible to perform communication. This improves transmission performance of a communication network.
