摘要： Method and device for notifying reference signal configuration information are disclosed. Channel state information-reference signal (CSI-RS) configuration information is coded to obtain one or more CSI-RS configuration codes. The CSI-RS configuration codes are sent to a terminal device. The terminal device determines, based on CSI-RS configuration codes, CSI-RS configuration information such as a quantity of antenna ports for transmitting a CSI-RS, a CSI-RS pattern, a CSI-RS period and an offset corresponding to the CSI-RS period.

摘要： A vehicle lighting control method includes that a roadside communications device sends a first message to a vehicle. The first message prompts the vehicle to illuminate a first target, and the first target is near a travel path that the vehicle is to pass through. Before passing the first target, the vehicle adjusts the vehicle into a first lighting mode in advance based on the first message to illuminate the first target.
