Abstract: Systems and methods for downlink transmission using a wideband unlicensed band carrier in 5G networks are described. The gNB determines, based on LBT, which LBT subchannel(s) in a BWP are available during a COT. The gNB transmits an indication of the available subchannels in DCI format 2_0 of a GC-PDCCH of one of the available subchannels and subsequently transmits a PDSCH using the available subchannel(s). The gNB may configure multiple opportunities during the COT and transmit the GC-PDCCH after the initial opportunity. The PDSCH is transmitted on all available subchannels during the COT and, during an initial portion of the COT, may transmit the PDSCH by puncturing symbols of the unavailable subchannels. The indication may include a bitmap of available subchannels or if the LBT outcome is not available, may indicate all or none of the subchannels or available or that the outcome is not available.
