1. A method for wireless communication, comprising:
first receiving, by a user equipment (UE) of a wireless communication network, a modulation and coding scheme index IMCS for demodulating a physical layer data channel of the network; and
demodulating, by the UE, 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 IMCS, 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.
