Abstract: The invention relates to the field of the technological equipment and technologies for mass production, in particular, vacuum equipment and vacuum technologies for functional thin film (cathode) formation (deposition) with required electrical, physical and chemical properties. 
     The method of LiCoO2 thin film formation (deposition) includes the deposition of LiCoO2 film on a substrate from metal cobalt (Co) target in lithium (Li) vapor by using of reactive magnetron sputtering in vacuum chamber. 
     The lithium vapor is fed into the magnetron system in a controlled manner. The feeding is carried out via a gas distributor. This gas distributor is connected to the working gas input and the lithium tank input. Lithium vapor feeding is effected by means of gas-carrier flow through a heated lithium tank. 
     This tank is heated to lithium melting point. The lithium vapor flow supply is controlled by changing the gas-carrier flow through the heated lithium tank. 
     The technological device for LiCoO2 film deposition contains a vacuum chamber, magnetron system with metal cobalt target, gas distributor, which is placed on perimeter or on the side of the magnetron system. Gas distributor is connected to the input of the working gas and to the input of the heated tank with lithium through the valves, the heated tank with lithium is connected with the input of gas-carrier. 
     The gas distributor can be designed as a cavity or labyrinth distributor. The heated lithium tank can be positioned inside or outside the vacuum chamber. The invention enables a radical reduction in the cost of mass production of thin-film solid-state batteries (batteries). The invention enables an increase in the deposition rate of the LiCoO2 film. The invention allows an increase in equipment productivity. 2 n.a. and 2 p.p.2tn.

The first codebook is determined based on a channel represented by one or more spatial-frequency domain column vectors, and the one or more spatial-frequency domain column vectors indicate the channel in joint spatial-frequency domain. In this solution, the first codebook may be determined based on the channel represented by the one or more spatial-frequency domain column vectors. Because the one or more spatial-frequency domain column vectors may represent the channel in joint spatial-frequency domain, that is, the first codebook represents the channel based on joint spatial-frequency domain, a joint spatial-frequency domain feature may be fully used, to explore a sparse feature of the channel, thereby improving system performance.
