Abstract
Methods and apparatuses are described herein for spectrum sharing and transmission mechanisms for different channel access priorities. For example, a wireless transmit/receive unit (WTRU) may be configured as either a high priority (HP) WTRU or a low priority (LP) WTRU, wherein a HP WTRU is configured to use a first channel access method for accessing the set of network resources and a LP WTRU is configured to use a second channel access method for accessing the same set of network resources, the second channel access method having a lower priority than the first channel access method. A set of protected network resources may be scheduled within the set of network resources for being accessed by the LP unit (e.g., over a limited period of time) with fewer channel access restrictions (e.g., with a higher priority channel access method than in any unprotected network resources).
