Abstract: Disclosed are a data transmission method, device, and system, which are used for resolving the problem of large overhead if an existing manner of sending a public message periodically is used in an ultra-dense network. The method comprises: user equipment sends an uplink request message, the uplink request message being used for requesting for obtaining public information of a first access node in an area in which the user equipment is located; and the user equipment receives the public information sent by the first access node. Because an access node in an area in which user equipment is located does not need to broadcast and send public information periodically, the access node can send, based on an uplink request of the user equipment, the public information, thereby improving the resource utilization and reducing the energy consumption.

Abstract: The present invention discloses a high temporal resolution Mueller matrix elliptical polarization measuring device and method. In the incident light path, four polarization modulation channels are used to split and modulate a pulse laser beam into four polarized beams in independent polarization states. Due to different light path differences, the pulse beams have a time interval of several nanoseconds, and thus four pulse laser beams are successively irradiated on the surface of the sample. In the reflected light path, six channel polarization detection modules are used to synchronously measure the Stokes vectors of the reflected beams on the sample surface. By using known incident and reflected Stokes vectors of the four pulse beams, linear equations can be solved to obtain the Mueller matrix of the sample.

Abstract: A duplication transmission method and device, used for solving the problem in existing technology of a scheme for implementing packet data convergence protocol (PDCP) duplication having yet to be implemented in a central unit/distribute unit (CU/DU) separation scenario. According to the embodiments of the present invention, after determining the need for PDCP duplication transmission on a radio bearer, a CU sends a PDCP data packet transmitted on the radio bearer to a DU and instructs the DU to carry out the PDCP duplication transmission; and the DU sends the PDCP data packet to multiple radio link control (RLC) entities corresponding to the radio bearer so as to carry out the PDCP duplication transmission. Since the CU may instruct the DU to perform the PDCP duplication transmission, the PDCP data packet is subject to duplication transmission in the CU/DU separation scenario, thereby further improving the system performance.

Since small cell information is broadcast in a macro cell, a terminal can measure a small cell according to the received small cell information before initiating an access request, instead of performing measurement during an access process.
