Abstract: A TOF sensor module is disclosed. The TOF sensor module includes a light source, a beam adjustment assembly, and a detection assembly. The light source is configured to emit m first beams at each of M moments, and transmit the m first beams to the beam adjustment assembly. The beam adjustment assembly is configured to: after adjusting the received m first beams into S second beams, project the S second beams to S regions of a detection surface, where M projection points that are in a same region of the detection surface and to which projection is performed at the M moments respectively have different locations. The detection assembly is configured to receive S optical echo signals from the detection surface at each of the M moments, and convert the S optical echo signals into S electrical echo signals for storage at each moment.

Abstract: The present disclosure relates to the field of communications technologies, and discloses a channel quality information determining method, an apparatus, and a system. The method may include: a terminal device obtains a configured TBS, and/or determines channel quality information of each of K segments of frequency domain resources based on the configured TBS and/or a time domain resource range. A frequency domain resource of the terminal device may be divided into N segments, where both N and K are integers greater than or equal to 1, and K is less than or equal to N. In some embodiments, the configured TBS may be fully considered when the channel quality information is determined, so that a network device properly may determine, based on the channel quality information, a frequency domain resource used to transmit a data packet.
