In this disclosure, methods for antenna combining to meet the pilot requirement of the massive MIMO system, and apparatuses for the same are provided. In a user equipment (UE) perspective of view, the UE transmits first pilot signals via each of multiple antennas of the UE, and receives antenna combining information from a base station. Here, the antenna combining information combines the multiple antennas into one or more antenna groups based on the first pilot signals, and each of orthogonal sequences is allocated to each of the antenna groups. The UE transmits second pilot signals using the allocated orthogonal sequences for each of the antenna groups. The second pilot signals can be used for estimating downlink channel from the base station to the UE.

A system and method for vending digital video discs is provided. A request is received from a user to complete a rental transaction for a first digital video disc. A database is queried to determine whether a quantity of a set of second digital video discs in a vending inventory exceeds a predetermined threshold. A discount offer notification is presented to the user to rent one of the set of second digital video discs, upon determining that the quantity of the set of second digital video discs exceeds the predetermined threshold. A second request from the user to rent one of the second set of digital video discs is received, and one of the set of second digital video discs is vended to the user.

A product discharging device includes: a lower pedal that is swingably disposed to move forward to and backward from a product storage passage storing input products in a vertical direction; an upper pedal that is swingably disposed to move forward to and backward from the product storage passage in an area above the lower pedal; a pedal stopper pin that is coupled to a pedal link linking the lower pedal and the upper pedal and that is movable with movement in the vertical direction of the pedal link; and a rotation stopper of which a tip is linked to the lower pedal and that is swingably disposed to move forward to and backward from the product storage passage along with the lower pedal.
