US Patent 10516417 Polar code encoding method and encoding apparatus

The present invention discloses a polar code encoding method and encoding apparatus. The method includes: mapping M reserved bits of a broadcast signaling respectively to M low-reliability information bits in K information bits of a polar code, and mapping remaining bits of the broadcast signaling to remaining information bits of the K information bits, to obtain bits after mapping, where M<K, and both M and K are positive integers; and performing polar code encoding on the bits after mapping, to obtain coded bits after encoding. Embodiments of the present invention can improve broadcast signaling transmission reliability.
