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.

Abstract: Transmit and/or receive beamforming may be applied to the control channel transmission/reception, e.g., in mmW access link system design. Techniques to identify candidate control channel beams and/or their location in the subframe structure may provide for efficient WTRU operation. A framework for beam formed control channel design may support varying capabilities of mBs and/or WTRUs, and/or may support time and/or spatial domain multiplexing of control channel beams. For a multi-beam system, modifications to reference signal design may discover, identify, measure, and/or decode a control channel beam. Techniques may mitigate inter-beam interference. WTRU monitoring may consider beam search space, perhaps in addition to time and/or frequency search space. Enhancements to downlink control channel may support scheduling narrow data beams. Scheduling techniques may achieve high resource utilization, e.g., perhaps when large bandwidths are available and/or WTRUs may be spatially distributed.

Abstract: A target wireless transmit/receive unit (WTRU) may determine a signal quality of a received sidelink positioning reference signal (SL-PRS) from each anchor WTRU of a sidelink positioning group. The target WTRU may determine whether the sidelink positioning group is suitable for sidelink positioning, for example based on whether a number of anchor WTRUs of the sidelink positioning group that are suitable for sidelink positioning exceeds a threshold value. The target WTRU may determine a position of the target WTRU, for example using the sidelink positioning group based on the number of anchor WTRUs of the sidelink positioning group that are suitable for sidelink positioning exceeding the threshold value.
