Methods, apparatuses directed to enabling tone reservations in wireless systems

A wireless transmit/receive unit (WTRU) comprising circuitry, including any of a transmitter, a receiver, a processor and a memory, the WTRU being configured to:

• determine that a power condition is satisfied;
• select a requested tone reservation (TR) configuration from a set of TR configurations based on the power condition being satisfied;
• transmit first information indicating the requested TR configuration;
• receive second information indicating the requested TR configuration or a different TR configuration of the set of TR configurations;
• and
• perform a transmission according to the requested TR configuration or the different TR configuration indicated in the received second information, wherein being configured to perform the transmission comprises being configured to:
• select a first set of resources for data transmission and a second set of resources adjacent to the first set of resources for a first tone reservation;
• and
• select a first transmit power for the first set of resources that is greater than a second transmit power for the second set of resources such that the data transmission is transmitted on the first set of resources at a power higher than a maximum power level.
