Abstract: A motion state estimation method and apparatus relate to the fields of wireless communication and autonomous driving/intelligent driving. The method includes a step of obtaining a plurality of pieces of measurement data using a first sensor, where each of the plurality of pieces of measurement data includes at least velocity measurement information. The method further includes obtaining a motion state of the first sensor based on measurement data in the plurality of pieces of measurement data that corresponds to a target reference object, where the motion state includes at least a velocity vector of the first sensor. In the present disclosure, a more accurate motion state of the first sensor can be obtained, and a vehicle's autonomous driving capability or advanced driver assistant system (ADAS) capability is further improved.

Abstract: A motion state determining method and apparatus are provided. The method includes determining a weight of a grid cell in a velocity grid W1 based on the measurement data obtained from a sensor, where the velocity grid W1 includes a plurality of grid cells. Each grid cell in the plurality of grid cells corresponds to one velocity vector, each velocity vector includes at least one velocity component, and the measurement data includes a velocity measurement value. The method further includes determining a motion state of the sensor based on the weight of the grid cell, where the motion state of the sensor includes a velocity vector of the sensor, and the velocity vector of the sensor includes at least one velocity component. The motion state determining method disclosed herein allows the motion state of the sensor to be accurately determined.

Abstract: Embodiments of the present invention disclose a sounding reference symbol SRS transmission method and a radio remote unit. The method, performed by a radio remote unit, includes: receiving a plurality of pieces of sampled data in a first period by using each antenna of an antenna array; if all of the plurality of pieces of sampled data are the SRS sampled data, buffering the plurality of pieces of sampled data; and reading the plurality of pieces of sampled data from the buffer in a second period, and sending the read plurality of pieces of sampled data to a baseband processing unit, where duration of the second period is longer than duration of the first period. Thus according the embodiments of the present invention, a time for transmitting the SRS sampled data is prolonged, so that bandwidth required for transmitting the SRS sampled data can be reduced.
