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.
