Abstract:
A method is performed by a wireless device for transmitting Hybrid Automatic Repeat Request (HARQ) feedback. The wireless device, for an uplink transmission to be transmitted on an uplink channel, applies a modified modulation constellation for a HARQ feedback. The modified modulation constellation has a modified Acknowledgment/Non-Acknowledgment (ACK/NACK) assignment as compared to a normal modulation constellation having a normal ACK/NACK assignment. The wireless device further transmits HARQ feedback in the uplink transmission according to the modified modulation constellation.
