Abstract:
Described are embodiments for transmitting hybrid automatic repeat request (HARQ) feedback information. In one embodiment, a wireless device receives a first downlink control information (DCI) indicating a first slot for transmission of uplink control information (UCI) comprising the HARQ feedback information. The wireless device receives a second DCI scheduling a plurality of physical uplink channels (PUSCHs) in a plurality of consecutive slots comprising the first slot. The wireless device multiplexes the UCI in a first PUSCH, of the plurality of PUSCHs, in the first slot. In response to a failed listen-before-talk (LBT) procedure for the first slot, the wireless device determines a second slot associated with a second PUSCH of the plurality of PUSCHs, and transmits, in response to a successful LBT procedure for the second slot, the UCI via the second PUSCH.
