Abstract: Embodiments of the present application provide a method and an apparatus for generating a code word using a Polar code encoding manner. A sequence has N bits, in which K bits are information bits. A matrix of N rows×N columns is used for encoding the sequence. Each row of the matrix has a weight that equals to total number of non-zero elements in the row, and ith row of the matrix corresponds to ith bit position of the sequence, i=1, 2, . . . , N. Each bit position of the N-bit sequence has a reliability. The K bit positions of the sequence that are occupied by the K information bits are selected according to reliabilities of the bit positions of the sequence and weights of the rows of the matrix. The code word is generated by multiplying the sequence with the matrix.

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