Blind decoding of uplink control channels

摘要: In 3GPP LTE, the uplink ACK and CQI bits are jointly coded prior to transmission maintain a low peak average ratio (PAR) waveform. Further, when data needs be transmitted, control channels multiplexed with transmission. However, due errors on downlink (DL) (UL) assignments, an evolved Base Node (eNB) receiver employ set of rules decode channels, minimize number blind decoding hypotheses. This innovation describes employed by reduce complexity computational overhead in part assuming that UE is responding grant download while providing for combinations which one or more types grants not received. Energy detection accordance metrics normalizing differing power controls enables selecting correct combination decoding.
