Abstract: A data forwarding method and device, a master base station and a slave base station are provided. The data forwarding method includes: after receiving a handover request message sent by a second master base station, if it is determined that a slave base station node is newly added, a service data adaptation protocol (SDAP) layer of a part of flows of a preset protocol data unit (PDU) session is configured at a master base station node, and an SDAP layer of the rest part of flows of the preset PDU is configured at the newly added slave base station node, sending a handover request response message carrying first preset information to a second master base station.

Abstract: A detection apparatus includes a scanning system, the scanning system includes a micro reflector array, and the micro reflector array includes M micro reflectors. The detection apparatus further includes P transceiver modules. An optical signal sent by the P transceiver modules is reflected by the M micro reflectors, and/or the P transceiver modules receive an optical signal reflected by the M micro reflectors. The P transceiver modules do not need to receive and send signals using one micro reflector, but may receive and send signals by using the M micro reflectors.

Abstract: A detection apparatus, a control method and control apparatus of the detection apparatus, a lidar system, and a terminal are provided. The detection apparatus includes at least one laser, at least one planar array detector, at least one lens assembly, at least one optical detector, and at least one micro electro mechanical system MEMS micromirror. The lens assembly is configured to focus reflected light of at least one first laser light beam to the planar array detector. The MEMS micromirror is configured to reflect reflected light of at least one second laser light beam to the optical detector.
