    摘要： A method performed by a wireless device is provided. The method is for accessing a cellular communications network in unlicensed spectrum. The wireless device performs (1202) a Listen-Before-Talk (LBT) procedure during any of two or more back-to-back random-access occasions. Responsive to a success of the LBT procedure, the wireless device performs the following. The wireless device generates (1204) a punctured random-access preamble responsive to a success of the LBT procedure. The punctured random-access preamble is adapted to create a puncturing gap at a beginning and/or an end of a respective one of the two or more back-to- back random-access occasions. A duration of the puncturing gap is based on the random-access priority of the wireless device. The wireless device then transmits (1206) the punctured random-access preamble if the LBT procedure is successful.

    摘要： A method performed by a wireless device (WD) comprises receiving a control message. The control message indicating at least a Modulation and Coding Scheme (MCS) and a scaling factor for a downlink shared channel. The scaling factor indicates a value less than 1. The method further comprises determining a transport block size (TBS) based on the MCS and the scaling factor indicated in the control message. A method performed by a network node comprises indicating in a control message at least a Modulation and Coding Scheme (MCS) and a scaling factor for a downlink shared channel. The scaling factor indicating a value less than 1. The method further comprises sending the control message to a User Equipment (UE), the control message enabling determination of a Transport Block Size (TBS) for a shared downlink channel.
