    Abstract: Methods and apparatuses for joint channel state information (CSI) measurement are described herein. A method may include receiving channel state information reference signals (CSI-RSs) from first and second transmit/receive points (TRPs), determining CSI, and selecting one of the TRPs as a primary TRP and a remaining one of the first TRP or the second TRP as a secondary TRP. The method may include reporting information indicating a first CSI for the primary TRP and receiving second CSI-RSs from the TRPs. The method may include determining a second CSI and a precoding matrix indicator (PMI) for the primary TRP, and determining channel coding information for the primary TRP. The method may include determining a second CSI for the secondary TRP, determining, based on channel coding information and the second CSI for the secondary TRP and a PMI for the secondary TRP, and reporting information indicating the PMI for the second TRP.

    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: A wireless transmit/receive unit (WTRU) may be configured to receive a primary synchronization signal (PSS) scrambled with a first sequence and to determine a PSS sequence index (uk) associated with the PSS and a first sequence index (wi) associated with the first sequence. The WTRU may be configured to determine a first parameter set based on the PSS sequence index (uk) and the first sequence index (wi) and to send information using at least one parameter from the determined first parameter set. The first parameter set may be associated with a waveform. The first parameter set may comprise at least one of: an indication of a waveform type and an indication of a multiplexing scheme. The information may be a physical random access channel (PRACH) transmission. The WTRU may be configured to determine a first offset based on the PSS sequence index (uk) and the first sequence index (wi).

    Abstract: A method performed by a wireless transmit/receive unit (WTRU) may compromise: receiving a downlink control information, wherein the DCI includes a multi-PDSCH priority indication; determining a priority for each of a two or more PDSCHs transmissions based on the multi-PDSCH priority indication; determining one or more scheduling parameters for each of the two or more PDSCH transmissions based on the determined priority of each of the two or more PDSCH transmissions; and receiving each of the two or more PDSCH transmissions using the respective determined scheduling parameters. The method may further compromise associating a first scheduling parameter with a first priority and a second scheduling parameter with a second priority, wherein the first priority is a high priority and the second priority is a low priority.
