Abstract: Systems, methods, and instrumentalities are disclosed to desynchronize transmissions in group-based operations. A group user equipment (UE), e.g., a UE that is a member of a group of UEs, may be in an inactive mode. The group UE may receive a multicast message indicating that the group UE may enter an active mode. For example, the group UE may use the active mode for periodic reporting of its monitoring activity to the network. The multicast message may indicate a mechanism for the group UE to use to send an uplink transmission to the network. The group UE may send the uplink transmission to the network at a transmission time indicated by the mechanism. The transmission time may be desynchronized from other UEs in the group.

Abstract: A method and apparatus for determining uplink power in a wireless transmit receive unit (WTRU). The WTRU operates in a carrier aggregated system. The WTRU is configured to receive a plurality of uplink power parameters indexed to one of a plurality of uplink carriers and receive a transmit power control command indexed to the one of the plurality of uplink carriers. The WTRU is configured to determine a pathloss of the one of the plurality of uplink carriers and determine a transmit power for the one of the plurality of uplink carriers based on the plurality of power parameters, the transmit power control command, and the pathloss.

Abstract: A wireless transmit/receive unit (WTRU) may receive first measurement indication information indicating an activation of measurement reporting. The WTRU may determine a first set of resource elements (REs) based on the first measurement indication information. Further, the first set of REs may be associated with measurement-related time and frequency resources. Also, the WTRU may receive one or more measurement-related signals in the indicated first set of REs. Additionally, the WTRU may perform a measurement of each measurement-related signal. The WTRU may transmit, based on the first measurement indication information, a measurement report based on the measurement of each measurement-related signal. Further, the WTRU may receive second measurement indication information indicating a deactivation of measurement reporting. Also, the WTRU may receive indication information regarding a plurality of sets of REs via radio resource control (RRC) signaling, including at least the first set of REs and a second set of REs.

Abstract: Approaches for idle mode operations for wireless transmit/receive units (WTRUs) with zero-energy (ZE) receivers are disclosed herein. A WTRU operating in idle mode, may receive using the main transceiver over a Uu interface, an energy harvesting (EH) configuration for use over a ZE air interface. The main transceiver may be turned off, and the ZE receiver as part of a ZE idle mode operation, may detect, over the ZE air interface, and harvest energy from ZE reference signals. The WTRU may calculate an amount of energy harvested from the ZE reference signals over a first time period. The WTRU may calculate a ZE idle mode operation energy consumption over the first time period. On a condition that the ZE idle mode operation energy consumption is greater than the harvested energy, the main transceiver may be turned on and the WTRU may enter a Uu interface idle mode operation.
