Abstract: Method, apparatus and systems are disclosed that may be implemented in a wireless transmit/receive unit (WTRU) and/or a wireless access point associated with the WTRU. In one representative method, the WTRU may be in an inactive mode or an idle mode prior to a paging occasion (PO). The WTRU may be configured to detect transmission of a number of synchronization signal blocks or reference signals associated with early paging indication (EPI) downlink control information (DCI). Based on the detected transmissions, the WTRU may perform a blind decoding on transmitted EPI DCI or sequence set to determine whether the WTRU is being paged at the PO or not. The blind decoding may use a pattern which relates the detected synchronization signal blocks or reference signals to a number of transmissions of the EPI DCI associated with the PO. Paging of the WTRU may be used to determine a light/deep sleep state of the WTRU.

Abstract: A wireless transmit/receive unit (WTRU) may identify a plurality of candidate satellite constellations. The WTRU may determine an elevation angle and/or an orbit associated with each of the plurality of candidate satellite constellations. The WTRU may select a satellite constellation from the plurality of candidate constellations for sell selection. The WTRU may identify a plurality of candidate beams associated with the selected satellite constellation. The WTRU may determine an RSRP/RSRQ for each of the plurality of candidate beams. The WTRU may determine a weighted ranking of the plurality of candidate beams. The WTRU may determine the weighted ranking using the determined RSRP/RSRQ, prevailing load intensities, elevation angle, dwelling duration, link switch probability, and/or a quality of service (QoS). The WTRU may select a beam from the plurality of candidate beams for cell selection. The WTRU may select the beam based on the weighted ranking.

Abstract: A method for initial timing synchronization for a WTRU to communicate with a network includes receiving an in-channel narrowband synchronization sequence from the network to enable initial coarse timing synchronization, determining coarse timing offset and a range between a beam source of a network transmitter and the WTRU, selecting a wideband sequence for fine timing synchronization using the estimated range, transmitting the selected wideband sequence for fine timing synchronization during an uplink timing occasion, receiving from the network a transmission of the selected wideband sequence for fine timing synchronization, and establishing fine timing synchronization between the WTRU and the network using the selected sequence.

Abstract: Method and apparatus for a WTRU to harvest energy from uplink signals of other WTRUs in a wireless network are disclosed. In an example, a method includes sending a message indicating resources and capability of energy harvesting (EH) from sets of resources of the plurality of resources; receiving one or more SRS super-sets, each SRS super-set being associated with a group of other WTRUs and at least one set of resources of the plurality of resources; determining a mapping between a receive beam and an SRS super-set; receiving uplink transmission patterns each being associated with an SRS super-set; selecting a receive beam from a set of receive beams based on the received uplink transmission patterns; and harvesting RF energy from uplink transmissions of one or more groups of other WTRUs using at least the selected receive beam and the received uplink transmission patterns.

Abstract: A WTRU may receive an indication of a set of baseline configurations (e.g., the set of baseline configurations or a pointer/index to the set of baseline configurations). The set of baseline configurations may include at least a first baseline configuration and a second baseline configuration. The WTRU may receive first information (e.g., a first signature), wherein the first information indicates that the first baseline configuration is a selected baseline configuration (e.g., a current SI baseline). The first information may be received via the low power receiver. The WTRU may receive and/or determine scheduling information. The scheduling information may include at least an indication of a first schedule associated with first update information. The WTRU may receive, in accordance with the first schedule, second information (e.g., a second signature). The second information may indicate the first update information (e.g., the first update information indicating an update to the selected baseline configuration).

Abstract: A method and configurations are discussed relative to a wireless transmit/receive unit (WTRU) in the form of a multi subscriber identity module (MUSIM). The paging information for the WTRU may be optimized for power consumption. The paging information may be modified to provide one or more of a maximum deep sleeping time duration requirement, a minimum number of power state transitions, and minimum power penalty associated with power state transitions. The modified paging information may set a paging occasion offset windows and a time direction indication associated therewith.

Abstract: Methods, apparatuses, systems, etc., directed to random channel access over zero energy (ZE) air-interface(s) are disclosed herein. In an embodiment, a wireless transmit/receive unit (WTRU) may receive a first reference signal. For example, the WTRU may determine that a first signal strength of the received first reference signal may fail to satisfy a strength condition, and responsively the WTRU may: (i) receive a transmission, (ii) determine a sequence and an occasion based on the received transmission, (iii) transmit using the determined sequence on the determined occasion, and (iv) receive a second reference signal from an interrogating WTRU.
