    Abstract: A wireless transmit/receive unit (WTRU) may receive configuration information indicating a set of physical channel frequency resources. The WTRU may receive indication information indicating an allocation of at least a subset of the set of physical channel frequency resources. Further, the WTRU may determine a time period, and one or more physical channel frequency resources from the subset of the set of physical channel frequency resources. The WTRU may transmit data in a physical shared channel transmission using the determined one or more physical shared channel frequency resources during the determined time period. Further, the WTRU may determine a time location for reception of hybrid automatic repeat request acknowledgement (HARQ-ACK) information associated with the transmitted data, and the determination of the time location may be based on the subset of the set of physical channel frequency resources. The WTRU may receive the HARQ-ACK information during the determined time location.

    Abstract: A WTRU may include a memory and a processor. The processor may be configured to receive beam grouping information from a gNB or transmission and reception point (TRP). The beam grouping information may indicate a group of beams that the WTRU may report using group-based reporting. The group-based reporting may be a reduced level of reporting compared to a beam-based reporting. The group-based report may include measurement information for a representative beam. The representative beam may be one of the beams in the group or represents an average of the beams in the group. Alternatively, the representative beam may be a beam that has a maximum measurement value compared to other beams in the group. The group-based report may include a reference signal received power (RSRP) for the representative beam and a differential RSRP for each additional beamin the beam group.

    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 and systems for sending and receiving an enhanced downlink control channel are disclosed. The method may include receiving control channel information via an enhanced control channel. The method may also include using the control channel information to receive a shared channel. The method may include detecting the presence of the enhanced control channel in a given subframe. The enhanced control channel may be transmitted over multiple antenna ports. For example, code divisional multiplexing and de-multiplexing and the use of common and UE-specific reference signals may be utilized. New control channel elements may be defined, and enhanced control channel state information (CSI) feedback may be utilized. The presence or absence of legacy control channels may affect the demodulation and or decoding methods. The method may be implemented at a WTRU.

    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 method and apparatus for use in a base station for transmitting information blocks is disclosed. A base station transmits a plurality of beams to a wireless transmit receive unit (WTRU). Further, the base station transmits broadcast information, using a beam of the plurality of beams, the transmitted broadcast information including a first information block and a second information block. Responsive to information in the transmitted second information block, the base station may receive a random access preamble. After the reception of the random access preamble, the base station may transmit a random access response. Responsive to information in the transmitted random access response, the base station may receive a message including control information indicating additional information blocks that the WTRU is requesting to receive. After reception of the received message, the base station may transmit the additional information blocks. The transmitted broadcast information may be periodically transmitted broadcast information.

    Abstract: A WTRU may be configured to receive, in a first search space (SS) group (SSG), a first downlink transmission. The first downlink transmission may comprise first configuration information associated with power saving and downlink transmission monitoring. The WTRU may be configured to monitor for a second downlink transmission based on the first configuration information. On a condition that the first configuration information indicates a first value, the WTRU may be configured to monitor in the first SSG. On a condition that the first configuration information indicates a second value, the WTRU may be configured to monitor in a second SSG. On a condition that the first configuration information indicates a third value, the WTRU may be configured to skip downlink transmission monitoring in the first SSG for a first interval and monitor in the first SSG. The WTRU may receive the second downlink transmission based on the first configuration information.
