    Abstract: The disclosed structures and methods are directed to transmission and reception of a radio-frequency (RF) wave. An antenna comprises a stack-up structure having a first control layer, a second control layer, a first and a second parallel-plate waveguides, and a plurality of through vias. The antenna further comprises a first central port and a second central port being configured to radiate RF wave into the two parallel-plate waveguides independently; vertical-polarization peripheral radiating elements integrated with the first control layer and configured to radiate RF wave in vertical polarization; and horizontal-polarization peripheral radiating elements integrated with the second control layer and configured to radiate RF wave in horizontal polarization. A central port for transmission of RF wave into the stack-up structure of the antenna is also provided. Each vertical-polarization peripheral radiating element is collocated with one of the horizontal-polarization peripheral radiating element such that they cross each other, and that a RF wave radiation beam may be steered at an angle of 0 to 360 degrees in the plane of the stack-up structure, around the central port

    Abstract: An information adding method and apparatus, to increase a quantity of terminals that can be represented by an identifier sequence. The method includes: performing, by a transmit end, polar code encoding on a first bit sequence to generate an encoded second bit sequence; adding, by the transmit end, a part or all of an identifier sequence to the second bit sequence to generate a third bit sequence, where the identifier sequence is used to identify a terminal; and sending, by the transmit end, the third bit sequence.
