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

This abstract first appeared for US patent application 17932976 titled 'NON-SQUARE QUADRATURE AMPLITUDE MODULATION IN WIRELESS COMMUNICATION SYSTEMS

Simplified Explanation

The abstract of the patent application describes a method for demodulating a physical layer data channel in a wireless communication network using non-square quadrature amplitude modulation (NS-QAM) with a modulation order and code rate that matches the spectral efficiency of square QAM (S-QAM) indicated by a received modulation and coding scheme index.

• The UE receives a modulation and coding scheme index (I) for demodulating the physical layer data channel.
• The UE demodulates the physical layer data channel using NS-QAM with a modulation order and code rate that matches the spectral efficiency of S-QAM indicated by the received index.
• 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.

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.
