Abstract: Current wireless networks do not allow machine type communication (MTC) devices to have long discontinuous reception (DRX) cycles or sleep lengths. A long DRX cycle may allow MTC systems and devices to operate with much longer DRX/Sleep cycles/periods. This may facilitate the MTC operations for infrequent system access or infrequent system reaching (e.g. paged once in a week) with no or low mobility and may allow MTC devices to sleep for a long time with low power consumption.

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: A system and methods for beam failure recovery and management for multi-carrier communications with beamforming are disclosed herein. A wireless transmit/receive unit (WTRU) may monitor for and detect a beam failure of a beam associated with a secondary cell (Scell). The WTRU may select an Scell candidate beam. The WTRU may transmit using a selected uplink (UL) resource in a primary cell (SpCell) a medium access control (MAC) control element (CE) including an indication of Scell beam failure and identifying the selected candidate beam. The WTRU may receive an Scell beam failure indication response on the SpCell indicating an SCell index and a downlink (DL) quasi co-location (QCL) reference associated with the Scell. The WTRU may verify that the DL QCL reference matches with the candidate beam. The WTRU may perform random access on the SCell using the selected QCL reference and the selected candidate beam.

Abstract: A wireless transmit receive unit (WTRU) may operate in a dual connectivity (DC) context. While in a RRC_INACTIVE state, the WTRU may receive a paging message from a first cell, which may be associated with a master cell group (MCG). The paging message may indicate that the WTRU is to respond to the paging message on another cell. Also, or alternatively, the paging message may indicate that data for the WTRU is available on an SCG bearer. The WTRU may select a second cell (e.g., a cell other than the first cell) from a secondary cell group (SCG) list, which may include one or more secondary cells. The WTRU may initiate a random access channel procedure with the second cell based on receiving the paging message from the first cell. The WTRU may receive data from the second cell via the SCG bearer while in the RRC_INACTIVE state.

Abstract: Embodiments contemplate wireless transmit/receive unit (WTRU) transmissions of different types of uplink channels and/or signals in a system deployment where multiple destination points may exist. Some embodiments contemplate that a WTRU may select the destination point of a transmission on a dynamic basis. In one or more systems where destination point selection from among multiple potential destination points may be possible for a WTRU transmission, some embodiments contemplate the determination of the handling of hybrid automatic repeat request (HARQ) retransmissions and for different power headroom reporting mechanisms. Embodiments also contemplate the reduction and/or inhibition of WTRU transmissions to destination points to which the WTRU may have lost connectivity.

Abstract: A wireless transmit/receive unit (WTRU) may receive one or more physical downlink shared channel (PDSCH) transmissions and each PDSCH transmission may be associated with downlink control information (DCI) and a group of PDSCH transmissions. Further, the WTRU may determine a first group or a second group based on an indication received in DCI associated with at least one of the PDSCH transmissions. Then, the WTRU may generate hybrid automatic repeat request (HARQ)-acknowledgment (ACK) feedback for data received in one or more PDSCH transmissions associated with the determined group. Moreover, the WTRU may transmit the HARQ-ACK feedback. In an example, the DCI which includes the indication may schedule a plurality of PDSCH transmissions included in the determined group. In another example, the DCI which includes the indication may further include a first codepoint mapped to the first group or a second codepoint mapped to the second group.

Abstract: A wireless device for determining wireless channel metrics and/or cell quality when accessing wireless resources. For example, the wireless device may use the determined channel metrics and/or cell quality when performing cell selection and/or cell reselection procedures. The wireless device may use the determined channel metrics and/or cell quality to trigger and report cell or frequency measurements in one or more cells neighboring the device's serving cell. The wireless device may use (e.g., further use) the determined channel metrics and/or cell quality to select a beam or sub-band for initial access to a cell. The wireless device may be employed within a wireless communications network that utilizes unlicensed wireless spectrum.

Abstract: A wireless transmit/receive unit (WTRU) may receive/transmit data by employing a discontinuous reception cycle, which may include an awake state and a sleep state. For example, while in an awake state, a WTRU may monitor a PDCCH for a subset of time instances. During the remaining time instances, the WTRU may enter a sleep state, in which the WTRU may switch its receiving circuitry off (e.g., to reduce power consumption). A WTRU may receive (e.g., may expect to receive) one or more transmissions, during an awake state, before entering a sleep state. The durations of an awake state and/or the durations of subsequent sleep states may be determined based on whether the WTRU receives a transmission during the awake state and/or what the transmission was for. The WTRU may modify the value of a sleep state timer based on previous sleep state and/or awake state timer values.
