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 apparatus for wireless transmit/receive unit (WTRU) power control are described. A method includes receiving a time domain resource allocation (TDRA) list configuration including entries, each including a resource allocation that includes a slot offset value. L1 signaling is received indicating a minimum slot offset value. Downlink control information (DCI) is decoded on a physical downlink control channel in a slot. An index is obtained from the decoded DCI, identifying an entry in the TDRA list. A particular slot offset value identified by the index is retrieved from the TDRA list and compared with the minimum slot offset value. If the particular slot offset value is less than the minimum slot offset value, the entry is invalid. If the particular slot offset value is greater than or equal to the minimum slot offset value, a physical downlink shared channel is received.

Abstract: Procedures, mechanisms, methods, and techniques are provided that trigger power saving mode (PSM) functionality in the at least one wireless transmit receive units, group of WTRUs or subset of the group of WTRUs. The trigger may be in response to an application layer request to set one or more predetermined PSM settings, wherein the trigger originates from one or more application servers (APs) directed to a core network by way of an interface such as an SCEF that may be included on a device (e.g., a gateway, computing device, and/or the like) and may be configured for enabling the application server to request enabling and disabling PSM functionality.

Abstract: A wireless transmit/receive unit (WTRU) may monitor a common physical downlink control channel (PDCCH) search space for a downlink control information (DCI) signal and a first radio network terminal identifier (RNTI). In an example, the DCI signal may include an uplink (UL)/downlink (DL) configuration indication. In a further example, the first RNTI may be associated with UL/DL configuration information. The WTRU may transmit UL data or receive DL data based on the received UL/DL configuration indication. In another example, the DCI may include a plurality of UL/DL configuration indications. In an additional example, a plurality of WTRUs may monitor the common PDCCH search space for the first RNTI. Also, the UL/DL configuration indication may indicate UL/DL configuration information on a symbol basis. Further, the WTRU may receive a second RNTI which is associated with the UL/DL configuration indication.

Abstract: Methods and apparatus are described herein for improved efficiency of a wireless transmit/receive unit (WTRU) transmitting uplink transmissions. A WTRU may receive configuration information including configured grant (CG) uplink resources. Further, the WTRU may determine a hybrid automatic repeat request (HARQ) process identifier (ID) based on a number of uplink slots per frame. Moreover, the WTRU may transmit an uplink transmission using the determined HARQ process ID and the CG uplink resources. In an example, the number of uplink slots per frame is determined based on a number of known downlink slots per frame. Additionally or alternatively, the number of known downlink slots per frame are included in the received configuration information. Additionally or alternatively, the number of known downlink slots per frame are included in first indication information received by the WTRU.

Abstract: A method performed by a first station (STA) may compromise: receiving, from an access point (AP) that has an established transmission opportunity (TXOP) with a second STA, a multi-user request-to-send (MU-RTS) transmission opportunity (TXOP) sharing (TXS) trigger frame, wherein the MU-RTS TXS trigger frame includes: (i) an indication that the AP is sharing the TXOP established with the second STA with the first STA, and (ii) an indication of a duration of the shared TXOP; and transmitting, in response to the MU-RTS TXS trigger frame, one or more uplink (UL) frames within the duration of the shared TXOP indicated by the MU-RTS TXS trigger frame.

Abstract: Systems, devices, and methods are disclosed for determining one or more clear channel assessment occasions. Techniques include performing one or more clear channel assessment (CCA) processes on a channel during the one or more CCA occasions to determine whether the channel is available at the one or more CCA occasion based on the one or more CCA processes. Techniques include sending the UL transmission in one or more UL subframes via the channel on at least a condition that the channel is determined to be available at the one or more CCA occasions. Techniques include performing the one or more CCA processes on the channel during another of the one or more CCA occasions on at least a condition that the channel is determined to be unavailable at a previous CCA occasion.

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.
