    Abstract: Methods, apparatuses, systems, etc. directed to beam management for, and/or for use in connection with, multiple cells and/or multiple transmission/reception points are provided. Among the methods is a method that may include any of determining first and second reference signals sets (RS sets) associated with first and second sets of beams; receiving information for first and second beam failure recovery (BFR) sets corresponding to the first and second RS sets, wherein the information indicates an RS set associated with candidate beams (CB-RS set) and an uplink resource set for each of the first and second BFR sets; determining beam failures based on the first and second RS sets; selecting the CB-RS set and UL resource set from the first or second BFR set; determining an RS of the selected CB-RS set; and transmitting information indicating the beam failures using uplink resources of the selected uplink resource set.

    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: Methods and apparatuses for path selection and duplication are described herein. A method performed by a Wireless Transmit/Receive Unit, WTRU, may comprise receiving (1501) configuration information regarding path selection, the configuration information including configured parameters associated with network conditions and/or WTRU conditions. For example, the configured parameters may include a radio threshold, a signal quality threshold, and/or a channel busy ratio/channel occupancy ratio. CBR/CR, threshold. The WTRU may monitor (1502) the current network conditions and/or WTRU conditions. If UL data becomes available (1503) for transmission, the WTRU may determine (1504) one or more paths for transmission based on the configuration information and the current conditions. The one or more paths may comprise a direct path, a sidelink path, both a direct path and a sidelink path, or two sidelink paths.

    Abstract: A wireless transmit/receive unit (WTRU) may include a transceiver and a processor. The WTRU may be configured to receive one or more downlink signals. The WTRU may be configured to receive configuration information indicating time and frequency resources for transmission of hybrid automatic repeat request (HARQ) acknowledgement (ACK). The configuration information may indicate a first sequence. The WTRU may be configured to determine a set of sequences to be used in response to the receipt of the one or more downlink signals. The set of sequences may be determined based on the indicated first sequence. The WTRU may be configured to send a second sequence from the set of sequences in the time and frequency resources to indicate HARQ-ACK. The second sequence may be selected based on a number of physical downlink control channel (PDCCH) monitoring occasions associated with the indicated HARQ-ACK.

    Abstract: Methods and apparatuses for seamless switching between frequency ranges are provided herein. A method may include: receiving information identifying channel state information (CSI) reference signal (CSI-RS) resources in a first frequency range (FR), where each of the CSI-RS resources in the first FR is associated with CSI-RS resources in a second FR and the second FR is a lower FR than the first FR; and measuring a signal quality of at least one of the CSI-RS resources in the first FR. The method may further include selecting a subset of the CSI-RS resources in the first FR or the second FR, wherein, on a condition that the measured signal quality meets or exceeds a threshold, the selected subset is in the first FR, and the selection is based on the measured signal quality. The method may further include reporting the measured signal quality.

    Abstract: Methods and apparatus for beam failure recovery (BFR) in wireless communications are provided. In an example, a method includes receiving configuration information of a set of reference signals (RSs) for monitoring and a set of candidate RSs for new beam selection, determining whether a number of the set of RSs is larger than a threshold, determining whether at least a subset of RSs of the set of RSs is failed, selecting at least a first RS and a second RS from the set of candidate RSs, based on the number of the set of RSs being larger than the threshold and at least the subset of RSs of the set of RSs being failed, transmitting a first uplink signal using a first uplink resource associated with the selected first RS, and/or transmitting a second uplink signal using a second uplink resource associated with the selected second RS.

    Abstract: Devices, methods, and systems for coverage extension. A bundle of repeated transmissions of a preamble are transmitted responsive to a reference signal received power (RSRP) being less than a threshold and a random access (RA) procedure being initiated. A random access response (RAR) window is monitored for a random access radio network temporary identity (RA-RNTI) corresponding to the repeated transmissions of the preamble. In some implementations, each of the repeated transmissions of the preamble is transmitted based on a spatial filter that is different from others of the repeated transmissions of the preamble. In some implementations, each of the repeated transmissions of the preamble comprises a preamble index that is different from preamble indices of others of the repeated transmissions of the preamble. In some implementations, the spatial filter comprises a transmission (Tx) beam. In some implementations, the bundle of repeated transmissions of the preamble comprises retransmissions of a msg1.
