Methods, architectures, apparatuses and systems for network energy savings
The disclosure pertains to methods and apparatus for network energy savings. A method may be implemented in a wireless transmit/receive unit (WTRU). The method may include receiving configuration information indicating a pattern of time periods during which a cell is available or unavailable and receiving a downlink control information (DCI) comprising an indication associated with an availability of the cell. The method may include determining that a resource may be included in a time period during which the cell may be determined by the WTRU to be available based on the indicated pattern of time periods and the indication. The method may include transmitting or receiving in the resource based on the resource being included in the time period during which the cell may be available.
