Systems, methods, devices, and instrumentalities are described herein related to conditional triggers for flight path update indications. A wireless transmit/receive unit (WTRU) may receive configuration information. The configuration information may indicate a trigger condition (e.g., threshold) associated with enabling transmission of a flight path update indication. The WTRU may determine that the threshold associated with enabling transmission of the flight path update indication is satisfied. Based on the threshold being satisfied, the flight path update indication may be transmitted. The WTRU may receive a request to transmit the updated flight path information and transmit the updated flight path information.

Conditional trigger for flight path update indication

A base station may be configured to send a first downlink control information indicating that a wireless transmit/receive unit (WTRU) is to transmit uplink data on a first uplink channel. The base station may be configured to receive a plurality of a same value over a second uplink channel in response to a triggering condition. The second uplink channel may be a control channel. The base station may be configured to sending a second downlink control information in accordance with the plurality of the same value over the second uplink channel. The plurality of the same value may be in response to the first downlink control information providing an insufficient amount to transmit uplink data over the first uplink channel. The base station may be configured to send an indication of logical channels that are subject to triggering of an uplink scheduling request.

Systems, apparatuses, and methods are disclosed for receiving downlink control information (DCI) that may include an indication of a reference measurement resource (RMR), receiving an indication of a measurement configuration, and receiving an indication of a feedback resource configuration. A measurement report based on the indication of an RMR, an indication of a measurement configuration, and an indication of a feedback resource configuration may be generated and may be transmitted to a network device.

Systems and methods for reference signal measurements in wireless systems

Techniques for uplink power control (e.g., for New Radio (NR)) are disclosed. A wireless transmit/receive unit (WTRU) may determine that the WTRU is to perform a first and a second transmissions using a first and a second transmission beams. The WTRU may determine an uplink transmission power for one or more of the first or second transmissions. For example, if the angular separation of the first and the second transmission beams is greater than a first separation threshold, the WTRU may determine the uplink transmission power having a first maximum power level parameter and a second maximum power level parameter. If the angular separation of the first and the second transmission beams is less than a second separation threshold, the WTRU determine the uplink transmission power having a shared maximum power level parameter. The WTRU may transmit the first and second transmissions using the first and second transmission beams, respectively.

The WTRU may include a processor configured to select data from one or more logical channels for transmission in accordance with the allocations. The WTRU may include a transmitter configured to transmit data from one logical channel on the RUL carrier and to transmit data from another logical channel on the SUL carrier in accordance with the allocations.

Supplementary uplink transmissions in wireless systems

ePDCCH may be provided. For example, a WTRU may receive a configuration for monitoring an ePDCCH resource. Based on the configuration, the WTRU may be configured to monitor and may monitor the ePDCCH resource on a particular subframe. Additionally, a WTRU may derive an aggregation level for a subframe associated with an aggregation level number N. The WTRU may transmit or monitor an ePDCCH using the aggregation level associated with the Nfor the subframe. A WTRU may also receive a reference signal. The WTRU may then determine the type of reference signal received. The WTRU may perform a demodulation of the PDSCH or ePDCCH using a demodulation timing based on the determined type. The ePDCCH or PDSCH may also be monitored or received by identifying a demodulation reference timing implicitly based on a location of one or more ePDCCH resources where the WTRU may receive DCI.
