Abstract:
1. Method, comprising: interpreting a modulation indication bit as a quadrature phase shift keying/quadrature amplitude modulation (QPSK/xQAM) indication if both a user equipment (UE) and a serving cell support 64 quadrature amplitude modulation (64QAM) according to the following condition: interpreting the 7 channelization code-set information bits in the high speed shared control channel (HS-SCCH) part 1 structure as defined in the 3GPP release 5 specification if quadrature phase shift keying (QPSK) is indicated; interpreting the 7 channelization code-set information bits in the high speed shared control channel (HS-SCCH) part 1 structure such that only 6 bits are used for code-set information and one bit is stolen for use for 16QAM/64QAM selection if xQAM is indicated by the modulation indication bit; and demodulating a received signal using the interpreted information.
