Systems, methods, and instrumentalities are described for handling positioning reference signals in a wireless communication system. The positioning reference signals may be assigned priorities that may be used to facilitate various operations of a wireless transmit/receive unit (WTRU) such as positioning related services, collision avoidance, measurement and reporting, etc. The WTRU may be configured with multiple muting patterns associated with the positioning reference signals and may switch between different muting patterns based on the priorities of the positioning reference signals and/or other downlink (DL) or uplink (UL) transmissions that may overlap or collide with the positioning reference signals.

Handling positioning reference signals in wireless systems

Systems, methods, and instrumentalities (e.g. aspects of entities, interfaces and procedures in a wireless transmit/receive unit (WTRU) and/or network layers L1, L2, l3) are disclosed for low latency medium access control (MAC) protocol data unit (PDU) assembly in wireless systems, such as 5G flexible radio access technology (RAT) (5gFLEX). Latency may be reduced, for example, by WTRU determination of network transmission parameters and signaling prior to a transmission grant. A WTRU may receive a modulation and coding scheme (MCS), resource range, etc. prior to a grant, e.g., for use in future grants. Data blocks may be incrementally created/encoded prior to a grant. Data units may be segmented, assembled and multiplexed, for example, based on data block sizes that allow MAC and radio link control (RLC) processing prior to a grant. Flexible grant sizes may be provided for early generation of transport blocks before a grant. A minimum guaranteed transport block size (TBS) may be signaled to permit early generation of a MAC PDU. Transmission parameters may be selected prior to a grant, for example, using blind decoding or a DCI reception procedure.

Medium access protocol data unit assembly in wireless systems

Systems, methods, and devices for transferring data with different reliabilities. A wireless transmit/receive unit (WTRU) is configured with a first modulation and coding set (MCS) table and a second MCS table. The WTRU monitors for a radio network temporary identifier (RNTI). If the WTRU detects a first value for the RNTI, data is transferred with a first reliability. If the WTRU detects a second value for the RNTI, data is transferred with a second reliability.

Methods, systems, and devices for transferring data with different reliabilities

A wireless transmit/receive unit (WTRU) may be configured to receive configuration information associated with a first transmission configuration indicator (TCI) state group and a second TCI state group. The WTRU may be configured to report first respective measured downlink received power values and first respective determined power reduction values. The WTRU may be configured to report second respective measured downlink received power values and second respective determined power reduction values. The WTRU may be configured to receive an indication of the first TCI state group via a downlink transmission. The WTRU may be configured to determine a first TCI state from the first TCI state group based on downlink received power information and power reduction information. The WTRU may be configured to send an uplink transmission based on the first determined TCI state.

Beam indication based on TCI state group

Systems for performing radiation exposure monitoring that accommodate operating in multiple frequency bands are provided. A WTRU may be configured to monitor radiation exposure by determining an averaged power over an evaluation period. The radiation may be measured over a moving averaging window. The averaged measured power may be compared against SAR or MPE limits which may be defined in terms of normalized fractions or ratios in dB. The WTRU may be configured to measure for an averaged power periodically and/or in response to triggers.

Specific absorption rate and maximum permitted exposure mitigation

A method and apparatus for performing a channel access procedure and transmitting a set of repetitions is disclosed. A wireless transmit/receive unit (WTRU) may be configured to receive information to transmit uplink data. The information may indicate a first number of nominal repetitions and a first number of symbols for each of the first number of nominal repetitions. The WTRU may be configured to determine a set of symbols associated with a first nominal repetition and to transmit a second number of actual repetitions in symbols associated with the first nominal repetition. The second number of actual repetitions and the symbols used to transmit the second number of actual repetitions may be based on an occurrence of an event during the set of symbols associated with the first nominal repetition. The set of symbols associated with the first nominal repetition may comprise one or more subsets of consecutive uplink symbols.

Methods and apparatus for PUSCH repetition

A method for determining a DRX operation in a wireless transmit receive unit (WTRU) that has information indicating multiple DRX configurations, includes selecting a first DRX configuration from the multiple DRX configurations based on a first cast type and an associated first quality of service (QoS) information for a first sidelink radio bearer (SLRB) configuration, selecting a second DRX configuration from the multiple DRX configurations based on a second cast type and an associated second QoS information for a second SLRB configuration, determining a sidelink monitoring time based on a combination of an active time associated with the first DRX configuration and an active time associated with the second DRX configuration, and monitoring a sidelink control channel using the determined sidelink monitoring time.

Methods for performing discontinuous reception on sidelink

Systems, methods, devices, and instrumentalities are described herein relate to explicit requests for flight path statuses. A wireless transmit/receive unit (WTRU) may transmit a first message indicating flight path information is available. The WTRU may receive a second message including a flight path reporting configuration. The flight path reporting configuration may request the flight path information. The flight path reporting configuration may include at least one of: a number of waypoints; whether to include timestamp information; or a configuration to periodically report flight path information updates. The WTRU may transmit an initial flight path message within a third message. At a configured periodicity, the WTRU may evaluate whether the flight path information has changed since a previous flight path report was transmitted.

Explicit request for flight path status

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.

The discovery signal may carry a payload for explicit information about user and/or service identity, and may be mapped to physical resources in such a way as to decouple transmission/reception of the discovery signal from downlink operations. A WTRU may measure a D2D discovery signal quality and report to the network.

Discovery signal generation and reception

A method and an apparatus for wireless transmission using multiple uplink carriers are disclosed. A wireless transmit/receive unit (WTRU) may transmit via a primary uplink carrier data, pilot and control channels for uplink transmissions on both uplink carriers, and transmit a data channel and a pilot channel via a secondary uplink carrier. Alternatively, the WTRU may transmit via a primary uplink carrier data, pilot, and control channels for uplink transmission on the primary uplink carrier, and transmit via a secondary uplink carrier data, pilot, and control channels for uplink transmissions on the secondary uplink carrier. Each uplink carrier may be associated with at least one specific downlink carrier such that the WTRU applies control information received on a downlink carrier to uplink transmissions on an uplink carrier associated with the downlink carrier on which the WTRU receives the control information.

Method and apparatus for transmitting data and control information on multiple uplink carrier frequencies
