Abstract: The multi-operating system device comprises a processor, a transceiver, and an output device. The processor is configured to host a first operating system in the foreground and a second operating system (OS2) in the background, or vice versa. The output device is configured to be controlled by an OS hosted in the foreground. The transceiver is configured to receive a S1 from a notification device over a communication system, the S1 indicating a notification associated to the OS2. The output device further is configured to output the notification associated to the second OS2 when the OS1 is hosted in the foreground.

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.

Abstract: The present invention provides channel interleaving method of a polar (Polar) code. The method includes: determining an M_r-row and M_c-column matrix used for interleaving, and permutating, based on permutation patterns of the column sequence numbers and/or permutation patterns of the row sequence numbers, the matrix into which the to-be-interleaved bits are written. The permutation patterns of the column sequence numbers are represented by: [Pc(0), Pc(1), . . . , Pc(ic), . . . , Pc(M_c−1)]. Pc(ic) is obtained by performing pruned bit reverse (PBR, pruned bit reverse)-based mapping on the column sequence number ic. The permutation patterns of the row sequence numbers are represented by: [Pr(0), Pr(1), . . . , Pr(ir), . . . , Pr(M_r−1)]. Pr(ir) is obtained by performing pruned bit reverse (PBR, pruned bit reverse)-based mapping on the row sequence number ir; and reading interleaved bits from the permutated matrix.
