Abstract: A first wireless transmit/receive unit (WTRU) may receive, from a second WTRU, sidelink control information (SCI), including first information indicating if a resource is reserved by the second WTRU, and second information indicating if the second WTRU is a power saving or non-power saving. The first WTRU may measure a reference signal receive power (RSRP) of signals transmitted by the second WTRU. The first WTRU may add a resource to a set of available resources if the first information indicates that the resource is not reserved by the second WTRU. If a resource is reserved, the WTRU may set an RSRP threshold to a first set or second threshold based on a power saving mode of the second WTRU. The first WTRU may add the resource to the set of available resources if the measured RSRP is less than the selected RSRP threshold.

Abstract: Systems and methods described herein are provided for beamforming and uplink control and data transmission techniques. Such techniques enable a UE to maintain at least one beam process for operation with multiple beams and/or points. A beam process may be indicated for transmission or reception over a downlink or uplink physical channel. Power, timing, and channel state information may be specific to a beam process. A beam process may be established as part of a random access procedure in which resources may be provisioned in random access response messages. Techniques are provided to handle beam process failures, to use beam processes for mobility, and to select beams using open-loop and closed-loop selection procedures.

Abstract: Methods, apparatus, systems, architectures, and interfaces for a wireless transmit receive unit (WTRU) performing sidelink communications are provided. A method may include any of: receiving SL transmission configuration information indicating: (1) a dedicated resource allocation for assistance transmissions, and (2) triggering conditions for performing an assistance transmission; on condition that: (i) a physical SL shared channel (PSSCH) transmission is received, by the WTRU from another WTRU, according to a semi-persistent reservation, and (ii) one or more of the triggering conditions for performing the assistance transmission has occurred: (a) performing sensing based on sensing parameters associated with the received PSSCH transmission, and (b) selecting a dedicated resource allocation according to a resource of the received PSSCH transmission; and transmitting, to any number of proximate WTRUs, an assistance transmission using the selected dedicated resource allocation, the assistance transmission including assistance information associated with the sensing performed by the WTRU.

Abstract: A wireless transmit/receive unit (WTRU) (e.g., a millimeter WTRU (mWTRU)) may receive a first control channel using a first antenna pattern. The WTRU may receive a second control channel using a second antenna pattern. The WTRU may demodulate and decode the first control channel. The WTRU may demodulate and decode the second control channel. The WTRU may determine, using at least one of: the decoded first control channel or the second control channel, beam scheduling information associated with the WTRU and whether the WTRU is scheduled for an mmW segment. The WTRU may form a receive beam using the determined beam scheduling information. The WTRU receive the second control channel using the receive beam. The WTRU determine, by demodulating and decoding the second control channel, dynamic per-TTI scheduling information related to a data channel associated with the second control channel.

Abstract: Methods and apparatuses are described herein for monitoring radio links between wireless transmit/receive units (WTRUs) and determining of radio link failure, and may be used, among others, for New Radio (NR) vehicular communication (V2X); a mode whereby WTRUs can communicate with each other directly. A radio link between a WTRU and another WTRU may be monitored independently per ongoing unicast and/or multicast link, and radio link failure (RLF) may be determined as a function of the monitoring.

Abstract: Beam management may be coordinated by a centralized coordinating entity, e.g., by a gNB, that configures and schedules Channel State Information Reference Signal, CSI-RS, transmissions for beam measurement and reporting. This centralized coordinating entity may not be available for Wireless Transmit-Receive Units, WTRUs, in a SideLink, SL, mode of operation, where resource allocation is performed by WTRUs in a distributed manner. WTRU procedures for establishing and updating an SL TCI state association are disclosed, including determining a spatial domain filter to use for an SL transmission. In these WTRU procedures, a WTRU may perform CSI-RS transmissions in an SL slot, e.g., multiplexed with a PSCCH/PSSCH transmission. The WTRU may receive, in reply, CSI reporting information comprising a spatial domain filter. For further SL TB transmissions for the SL, the WTRU may use the spatial domain filter.

Abstract: A transmitting wireless transmit/receive unit (Tx WTRU) may receive configuration information that indicates one or more parameters. The one or more parameters may be associated with resource selection. The Tx WTRU may determine a first resource selection window and a second resource selection window. The first resource selection window may be associated with an active time of a receiving wireless transmit/receive unit (Rx WTRU). The second resource selection window may be associated with an inactive time of the Rx WTRU. The Tx WTRU may determine a first number of candidate resources associated with the first resource selection window. The Tx WTRU may determine a first number of candidate resources associated with the second resource selection window. In examples, the Tx WTRU may increase the first number of candidate resources associated with the first resource selection window to a second number of candidate resources associated with the first resource selection window.

Abstract: 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.

Abstract: A wireless transmit/receive unit (WTRU) may be configured to measure a downlink quality associated with at least one first beam. The WTRU may be configured to determine whether the measured downlink quality associated with the at least one first beam is below a threshold value. The WTRU may be configured to receive at least one control channel transmission using a determined second beam, based on, in part, a determination that the measured downlink quality associated with the at least one first beam is below the threshold value. The determined second beam used to receive the at least one control channel transmission may be a same beam that is used to receive an associated data channel transmission. The determined second beam may be from a set of beams. The set of beams may be received via higher layer signaling.
