Abstract

The application provides an encoding method, a decoding method, devices and equipment. The method comprises the following steps: sending equipment determines the location of an information bit, the location of a fixed bit and the location of an auxiliary bit, configures the information bit, the fixed bit and the auxiliary bit in a sequence to be encoded according to the determined locations, and then obtains a scrambling sequence, determines a bit set to be scrambled in the fixed bit and/or the auxiliary bit, scrambles the bits in the bit set to be scrambled according to the scrambling sequence to obtain a scrambled sequence, then performs polarization coding to obtain an encoded sequence, and sends the encoded sequence; and receiving equipment performs decoding verification after receiving a sequence to be decoded, performs verification when decoding to the location of the scrambled bit, and ends the decoding process if the verification fails. Thereby, signals that do not belong to the sending equipment can be excluded in advance, the decoding delay can be reduced, and the detection can be 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 is a new type of channel coding proposed by E.Ar1kan in 2008. Polar codes are designed based on channel polarization (Channel Polarization), and are the first constructiv...
