Methods and apparatus for power saving in a wireless network are disclosed. A Wireless Transmit/Receive Unit (WTRU) may comprise a transmitter, a receiver, and a processor. The processor may determine a processing state pertaining to behavior of the WTRU and determine a minimum amount of resources to be processed for one or more sets of physical resources based on the determined processing state. Each respective set of physical resources may comprise resources in time, and any of frequency or space. For each respective set of physical resources, the time may comprise a frame structure associated with a numerology applicable to the respective set of physical resources, the frequency may comprise any of a frequency location, a bandwidth, or the numerology, and the space may comprise one or more beams. The processor may process the determined minimum amount of resources of the one of more sets of physical resources.
