Abstract
A method performed by a wireless device (410) includes transmitting an uplink, UL, burst to a network node (460). The UL burst includes UL control information, UCI, multiplexed in a Physical Uplink Shared Channel, PUSCH. The UCI carries one or more parameters for unlicensed operation, and the UL burst has an associated UL burst structure. The UL burst structure includes a first slot, a full slot, and a last slot.

A method performed by a wireless device, the method comprising:
- transmitting an uplink (UL) burst to a network node, the UL burst comprising UL control information, UCI, multiplexed in a Physical Uplink Shared Channel, PUSCH, the UCI carrying one or more parameters for unlicensed operation, the UL burst having an associated UL burst structure, the UL burst structure comprising a first slot, a full slot, and a last slot, wherein each of the first slot, the full slot, and the last slot comprise an associated pattern of one or more demodulation reference signals.
A method performed by a base station, the method comprising:
- receiving an uplink, UL, burst from a wireless device, the UL burst comprising UL control information, UCI, multiplexed in a Physical Uplink Shared Channel, PUSCH, the UCI carrying one or more parameters for unlicensed operation, the UL burst having an associated UL burst structure, the UL burst structure comprising a first slot, a full slot, and a last slot, wherein each of the first slot, the full slot, and the last slot comprise an associated pattern of one or more demodulation reference signals, the method further comprising:
- detecting the pattern of one or more demodulation reference signals in each of the first slot, the full slot, and the last slot;
- and
- determining the slot type based on the detected pattern of one or more demodulation reference signals in each of the first slot, the full slot, and the last slot.
A wireless device configured to:
- transmit an uplink, UL, burst to a network node, the UL burst comprising UL control information, UCI, multiplexed in a Physical Uplink Shared Channel, PUSCH, the UCI carrying one or more parameters for unlicensed operation, the UL burst having an associated UL burst structure, the UL burst structure comprising a first slot, a full slot, and a last slot, wherein each of the first slot, the full slot, and the last slot comprise an associated pattern of one or more demodulation reference signals.
A base station configured to:
- receive an uplink, UL, burst from a wireless device, the UL burst comprising UL control information, UCI, multiplexed in a Physical Uplink Shared Channel, PUSCH, the UCI carrying one or more parameters for unlicensed operation, the UL burst having an associated UL burst structure, the UL burst structure comprising a first slot, a full slot, and a last slot, wherein each of the first slot, the full slot, and the last slot comprise an associated pattern of one or more demodulation reference signals.
