Abstract: A WTRU may receive a plurality of monitoring configurations. The plurality of monitoring configurations may be associated with a plurality of sub-bands. The WTRU may apply a monitoring configuration based on the location of a slot inside or outside of a COT. For example, the WTRU may apply (e.g., use) a first monitoring configuration outside a COT. The WTRU may apply a second monitoring configuration in a first slot of a COT. The WTRU may apply a third monitoring configuration to the slots of a COT subsequent to the first slot of the COT. The WTRU may switch back to the first monitoring configuration on a condition that the COT ends.

Abstract: Methods and systems for transmitting uplink control information and feedback are disclosed for carrier aggregation systems. A user equipment device may be configured to transmit uplink control information and other feedback for several downlink component carriers using one or more uplink component carriers. The user equipment device may be configured to transmit such data using a physical uplink control channel rather than a physical uplink shared channel. The user equipment device may be configured to determine the uplink control information and feedback data that is to be transmitted, the physical uplink control channel resources to be used to transmit the uplink control information and feedback data, and how the uplink control information and feedback data may be transmitted over the physical uplink control channel.

Abstract: Methods, systems, and devices for addressing timing advance (TA) in non-terrestrial network communication is disclosed herein. A wireless transmit and receive unit (WTRU) may receive system information from a base station attached to an airborne or spaceborne vehicle that indicates a physical random access channel (PRACH) resource. The WTRU may determine a timing offset based on a plurality of information, such as the location information and the system information. The WTRU may transmit a preamble using the timing offset via the PRACH resource. The base station may receive the preamble and send a random access response (RAR) that includes, for example, a TA command. The WTRU may receive the RAR including the TA command and combine the timing offset with the TA command to determine an actual TA, after which the WTRU may use the actual TA for uplink transmissions.

Abstract: Methods for receiving and transmitting downlink transmissions with increased reliability are provided. A method includes receiving configuration information defining first and second search space sets. The first search space set includes a first one or more search spaces each including a plurality of physical downlink control (PDCCH) candidates. The second search space set includes a second one or more search spaces each including a plurality of PDCCH candidates. The configuration information indicates that the first and second one or more search spaces are linked. The method further includes receiving downlink control information (DCI) by detecting, based on the received configuration information, a first transmission using PDCCH candidates of the first one or more search spaces, detecting a second transmission using PDCCH candidates of the second one or more search spaces, and decoding at least one of the first transmission or the second transmission.

Abstract: Methods, apparatus and systems are disclosed. One representative method implemented by a wireless transmit/receive unit includes determining a first beamforming matrix; sending, to a network entity, an indication of the first beamforming matrix; and receiving, from the network entity, an indication of a second beamforming matrix determined by the network entity from at least the first beamforming matrix for beamforming data for transmission.

Abstract: Systems, methods, and instrumentalities are disclosed that may be associated with HARQ-ACK codebook adaptations. A WTRU) may be configured with multiple physical uplink channels, e.g., physical uplink control channels (PUCCHs), in a slot. Each physical uplink channel may have a respective HARQ-ACK codebook. In examples, the WTRU may determine that a first physical uplink channel and a second physical uplink channel overlap in a slot. In such a case, the WTRU may determine that a first HARQ-ACK codebook associated with the first physical uplink channel has a higher priority than a second HARQ-ACK codebook associated with the second physical uplink channel. The WTRU may transmit the first HARQ-ACK codebook on the first physical uplink channel in the slot. The WTRU may send part of the second HARQ-ACK codebook in the slot and part of the second HARQ-ACK codebook in a subsequent slot (e.g., a next slot, a future slot, etc.).

Abstract: Systems, methods and instrumentalities are disclosed for decoding data. For example, it may be determined, in a current slot, whether data received in a previous slot is decoded successfully. The data received in the previous slot may be included in a Physical Downlink Shared Channel (PDSCH). If the data received in the previous slot is not decoded successfully, preemptive multiplexing information may be detected in a first search space. The data received in the previous slot may be decoded, for example, using detected preemptive multiplexing information. The preemptive multiplexing information may be of a current slot. The preemptive multiplexing information may be comprised in a first DCI. A second search space of the current slot may be searched. For example, the second search space may be searched for a second DCI. The first DCI and the second DCI may be different.

Abstract: A method implemented by a Wireless Transmit/Receive Unit (WTRU) includes receiving a DeModulation Interference Measurement (DM-IM) resource, determining an interference measurement based on the DM-IM resource, and demodulating a received signal based on the interference measurement. An interference is suppressed based on the interference measurement. At least one DM-IM resource is located in a Physical Resource Block (PRB). The DM-IM resource is located in a PRB allocated for the WTRU. The DM-IM resource is a plurality of DM-IM resources which form a DM-IM pattern, and the DM-IM pattern is located on a Physical Downlink Shared Channel (PDSCH) and/or an enhanced Physical Downlink Shared Channel (E-PDSCH) of at least one Long Term Evolution (LTE) subframe. The DM-IM resources are different for different Physical Resource Blocks (PRB) in the LTE subframe. The DM-IM is located in a Long Term Evolution (LTE) Resource Block (RB), and the DM-IM pattern is adjusted.

Abstract: Methods, apparatuses, systems, devices, and computer program products directed to phase-continuous frequency selective precoding are provided. Included among these classes are methods for use in connection with dynamic precoding resource block group (PRG) configuration and with codebook based transmission configuration. A representative of such methods may include any of receiving signaling indicating transmit precoding information; determining a candidate PRG size using any of the transmit precoding information, a rule for determining a PRG size and configured PRG sizes; and configuring or reconfiguring a wireless transmit/receive device in accordance with the candidate PRG size. Another of the representative methods may include reporting a transmission coherence capability of a wireless transmit/receive unit; receiving a codebook subset restriction (CBSR) commensurate with the transmission coherence capability; determining a transmit precoding matrix indices (TPMI) size based on the CBSR; receiving a TPMI; and detecting or decoding the TPMI based on the determined TPMI size.

Abstract: Systems and/or methods for supporting communications at a reduced bandwidth with a full bandwidth network such as a long-term evolution (LTE) network may be disclosed. For example, inband assignments such as downlink assignments and/or uplink grants may be provided and/or received and transmissions may be monitored and/or decoded based on the inband assignment. Additionally, information (e.g. a definition or configuration) associated with an ePDCCH may be provided and/or received and ePDCCH resources may be monitored and/or decoded based on such information. An indication for support of a reduced bandwidth by the full bandwidth network may also be provided and/or received and control channels in the reduced or narrow bandwidth may be monitored and/or decoded based on the indication. A PRACH preamble and/or a multi-type subframe definition may also be provided and/or used for support of such a reduced bandwidth.
