    Abstract: Systems, methods, and devices for addressing power savings signals in wireless communication. A wireless transmit receive unit (WTRU) may monitor for an energy saving signal (ESS) while the WTRU is asleep (e.g., prior to a discontinuous reception (DRX) ON duration that includes one or more search spaces). The WTRU may measure the energy of the ESS. If the ESS is below a threshold, the WTRU fallback to a default operation or continue in a current operating mode (e.g., remain asleep to save power). If the ESS is above a threshold, the ESS may be received using a coverage enhancement (CE) level based on a parameter associated with a search space. The parameter may be the highest aggregation level of the one or more search spaces.

    Abstract: Systems, methods, and instrumentalities are described herein for wireless transmit/receive unit (WTRU) power saving (e.g., for idle mode). A WTRU may determine a time window associated with one or more paging indicators. The WTRU may monitor for a paging indicator (e.g., a first paging indicator) in the time window. The WTRU may monitor for another paging indicator (e.g., a second paging indicator) in the time window. The WTRU may receive system information blocks (SIBs) if a wake up indication for the WTRU is received in a single paging indication and the paging indicator is the first paging indicator. The WTRU may monitor for a paging PDCCH at a monitoring occasion of a PO in a paging frame if the second paging indicator is received and includes an indication for the WTRU to wake up.

    Abstract: Methods, apparatuses, systems, devices, and computer program products directed to low latency, bandwidth efficient communications with low duplex spacing (LDS) are provided. The LDS communications are facilitated by partitioning a (e.g., single) channel to include DL and UL portions (or “bandwidth fragments”) with low duplex spacing between the DL and UL portions. Among the new methodologies provided herein is a method that may include partitioning a channel to include a first bandwidth fragment that is bounded by, and overlaps or has low duplex spacing with, a pair of non-overlapping bandwidth fragments that are symmetrically offset symmetrically from a reference frequency associated with the channel; receiving a receive signal while transmitting a transmit signal on either the first bandwidth fragment or the pair non-overlapping bandwidth fragments; and using any of cancellation and interference reduction to reduce a portion of the receive signal that corresponds to the transmit signal.
