Claim of US Patent No. 10,973,084

1. A method for wireless communication by a wireless node, comprising:determining if a narrowband region within an unlicensed radio frequency (RF) spectrum is available for transmissions, wherein the determining comprises determining if the narrowband region is available based on a configuration of transmission gaps assigned to support sharing of the narrowband region;
performing a clear channel assessment (CCA) within the narrowband region; and
transmitting on the narrowband region if it is determined the narrowband region is available, wherein the transmitting comprises transmitting both a narrowband physical downlink control channel (NB-PDCCH) and a narrowband physical downlink shared channel (NB-PDSCH) after a single passed CCA, a duration of the NB-PDCCH and the NB-PDSCH being dynamically adjusted.
