Abstract:
An electronic nameplate display method includes obtaining a position of a face of a participant in a video image and identity information of the participant, determining a display position and a size of an electronic nameplate in the video image based on the position of the face in the video image, and displaying the identity information of the participant using the electronic nameplate. In this method, self-adaptive adjustment of the electronic nameplate is implemented based on the position of the face.
Abstract:
Embodiments of the present disclosure provide a base station and a beam forming method. The method includes: determining, according to uplink sounding signals separately received using m beams, an uplink receive power of each beam in the m beams, where m is a positive integer greater than 2; selecting n beams from the m beams according to the uplink receive power of each beam in the m beams, where 2≤n
Abstract:
An apparatus and a method for multi-user scheduling in a MIMO system are disclosed. In an embodiment the method includes, receiving, by a base station, PMIs and CQIs of first codewords and second codewords, where the PMIs and the CQIs are fed back by N UEs; grouping UEs whose PMIs are the same into one pairing group to divide the N UEs into M pairing groups; and determining a user pairing combination of each pairing group according to a CQI of a first codeword of each UE in the pairing group and a CQI of a second codeword of each UE in the pairing group. The method further includes determining an optimal user pairing combination from M user pairing combinations. The base station schedules two UEs in the optimal user pairing combination simultaneously.

Abstract:
A contactor drive circuit includes a power supply, a processor, a line connection and control unit, a first drive end, and a second drive end; when a contactor is connected between the first drive end and the second drive end, the processor determines, according to a value of a current flowing through the contactor, a type of the contactor connected between the first drive end and the second drive end; and according to a result of the determining, the processor controls the line connection and control unit to enable the first drive end to be electrically connected to an anode of the power supply, and controls the second drive end to be electrically connected to a cathode of the power supply.
Abstract:
Embodiments of the present invention provide a method for communication through a distributed antenna array system and an array system. The antenna array system includes a number of antenna units, a baseband resource pool, a radio frequency resource pool, and a controller. The controller is configured to monitor a signal state of a user equipment under a coverage area of a macrocell, to determine an antenna unit that provides a service to the user equipment, and, according to a capability of the user equipment, determine whether to perform coordinated transmission of a plurality of antennas and a corresponding transmission mode for the user equipment, and then to configure an antenna resource for the user equipment, so that the baseband resource pool and the radio frequency resource pool control the configured antenna resource to provide a communication service for the user equipment.
