Abstract

Sub-band (SB) indications and listen-before-talk (LBT) outcomes may be used to adjust communications between devices such as wireless terminals and base stations. For example, a wireless terminal may receive SB indications including SB configurations and/or LBT outcomes of a base station, and other information such as a remapped CORESET. Similarly, a terminal may determine that a physical resource block (PRB) is invalid based at least in part on whether the PRB overlaps with a guard band. The terminal may be arranged to adjust its searches and transmissions based on received SB indications, and to provide the base station with LBT outcomes of the terminal.
