WIRELESS COMMUNICATION METHODS AND DEVICES, AND COMPUTER-READABLE INVARIANT MEDIA

Abstract

The invention relates to a method and apparatus for wireless communication and a means of invariant reading by a machine. Specifically, the invention relates to wireless communication systems and methods relating to the signaling of the start of transmissions for transmissions in a frequency spectrum shared by multiple network operators. The first wireless communication apparatus communicates, with the second wireless communication apparatus, a circular prefix length (CP) configuration to create a listen-before-talk (LBT) duration associated with the first communication signal. The first wireless communication apparatus communicates, with the second wireless communication apparatus, the first communication signal containing a CP extension of a length based on the CP length configuration.
