NON-SQUARE QUADRATURE AMPLITUDE MODULATION IN WIRELESS COMMUNICATION SYSTEMS - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240097961 titled 'NON-SQUARE QUADRATURE AMPLITUDE MODULATION IN WIRELESS COMMUNICATION SYSTEMS

Simplified Explanation

The abstract of the patent application describes a method where a wireless communication device receives a modulation and coding scheme index, demodulates a physical layer data channel using non-square quadrature amplitude modulation (NS-QAM) with a modulation order and code rate corresponding to a spectral efficiency (SPEFF) equal to that of square QAM (S-QAM), and has an effective channel code rate no larger than the code rate for which the device may skip decoding a transport block in an initial received transmission.

  • Explanation of the patent/innovation:
 * Wireless communication device receives modulation and coding scheme index.
 * Demodulates physical layer data channel using NS-QAM with specific modulation order and code rate.
 * NS-QAM has spectral efficiency equal to S-QAM.
 * Effective channel code rate of NS-QAM is limited to allow skipping decoding of transport block in initial transmission.

Original Abstract Submitted

a ue of a wireless communication network first receives a modulation and coding scheme index ifor demodulating a physical layer data channel of the network. the ue then demodulates the physical layer data channel with a non-square quadrature amplitude modulation (ns-qam) having a modulation order and code rate corresponding to a spectral efficiency (speff) substantially equal to a speff of a square qam (s-qam) speff indicted by the i, where the ns-qam has an effective channel code rate no larger than the code rate for which the ue may skip decoding a transport block in an initial received transmission.
