Abstract

The invention provides an encoding method, a decoding method, a decoding device and equipment, and the method comprises the steps that: enabling sending equipment to determine the position of an information bit, the position of a fixed bit and the position of an auxiliary bit, and configure the information bit, the fixed bit and the auxiliary bit in a to-be-encoded sequence according to the determined position; and then obtaining a scrambling sequence, determining a to-be-scrambled bit set in the fixed bits and / or the auxiliary bits, scrambling bits in the to-be-scrambled bit set according tothe scrambling sequence to obtain a scrambled sequence, and then performing polarization coding to obtain a coded sequence for transmission; and enabling the receiving equipment to receive the to-be-decoded sequence, then perform decoding verification, performing verification when decoding to the scrambling bit position, and ending the decoding process if the verification fails. Signals which do not belong to the sending device are eliminated in advance, decoding delay is reduced, and detection is accelerated.

Description

technical field [0001] The present application relates to communication technology, and in particular to an encoding method, decoding method, device and equipment. Background technique [0002] The rapid evolution of wireless communication indicates that the future 5G communication system will present some new features. The three most typical communication scenarios include enhanced Mobile Broadband (eMBB), massive Machine Type Communications (mMTC) And Ultra-Reliable and Low Latency Communications (URLLC). The requirements of these communication scenarios will pose new challenges to the Long Term Evolution (Long Term Evolution, LTE) technology. As the most basic wireless access technology, channel coding is one of the important research objects to meet the needs of 5G communication. [0003] Polar codes (Polar Codes) were developed in 2008 by A new type of channel coding is proposed. Polar codes are designed based on channel polarization (Channel Polarization), and are...
