Abstract: Disclosed in the present invention are a method and a system for ensuring the failure atomicity in a non-volatile memory, which belong to the field of computer storage.

Abstract: Embodiments of the disclosure provide a polar channel coding method, a device, and a system. The method includes: obtaining, by a sending apparatus, a target coding scheme, where the target coding scheme includes a mother code length N and a quantity K of information bits, N is an integral power of 2, both N and K are positive integers, and N>K; selecting, by the sending apparatus, a target coding table from a plurality of candidate coding tables based on the target coding scheme, where the plurality of candidate coding tables are pre-stored in the sending apparatus; and coding, by the sending apparatus, the K information bits based on the target coding table to obtain a target coding sequence. Embodiments of the disclosure can reduce complexity of polar channel coding.

Abstract: Transmission methods for a paging indication channel in code division multiple access (CDMA) mobile communication system are provided, wherein signals are transmitted when paging indication bits indicate that user equipment has paging information, and when the user equipment has no paging information, the corresponding paging indication bits are set to 0, and the transmission of the signals are closed off. For example, it assumes that the number of the user equipment supported by a paging indication channel is 144, and the total bits are 288. If only one user equipment is paged at this time, it is required to transmit only two bits, and the signals of the other 286 bits will not be transmitted. Therefore, comparing to prior transmission methods for a paging indication channel, the methods in the present invention significantly reduce transmission power and interference and increase the capacity of the entire system.
