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.

Abstract: An apparatus for a UE includes processing circuitry coupled to memory. To configure the UE for shared spectrum channel access in a 5G-NR system, the processing circuitry is to decode a synchronization signal (SS)/physical broadcast channel (PBCH) block (SSB) to obtain a master information block (MIB). System information block 1 (SIB1) configuration information is determined using the MIB. The SIB1 configuration information is used to configure a Type 0 PDCCH common search space (CSS) set (CORESET). The processing circuitry is to monitor for a PDCCH in the Type 0 PDCCH CSS set over slots that include Type 0 PDCCH monitoring occasions. At least one of the slots includes the SSB and the CORESET multiplexed according to multiplexing pattern 1. The PDCCH is detected in at least one of the Type 0 PDCCH monitoring occasions. A SIB1 is decoded using downlink control information (DCI) received via the detected PDCCH.

Abstract: Various embodiments herein provide techniques for grant-based and configured grant physical uplink shared channel (PUSCH) transmissions in New Radio (NR) systems operation in unlicensed spectrum. Some embodiments relate to identification, based on an index to a table, a combination of a listen-before talk (LBT) type, an offset, and a channel access priority class (CAPC). Some embodiments relate to selecting, based on a duration of a first uplink (UL) transmission that is to follow a received downlink (DL) transmission, one of CAT-1 LBT and CAT-2 LBT. Other embodiments may be described and/or claimed.
