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 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: A method and apparatus for determining Physical Random Access Channel (PRACH) resources and using beams are disclosed herein. In an example, a wireless transmit/receive unit (WTRU) may receive a broadcast message or a radio resource control message from base station that includes correspondence information regarding the plurality of beam reference signals, wherein the correspondence information designates at least one set of PRACH resources for each of the plurality of beam reference signals. In addition, the WTRU may measure a plurality of beam reference signals transmitted from a base station. Further, the WTRU may select a beam reference signal from among the plurality of measured beam reference signals. The WTRU may determine a set of PRACH resources designated for the selected beam reference signal based on the received correspondence information. Moreover, the WTRU may transmit a PRACH signal using at least one PRACH resource of the determined set of PRACH resources.

Abstract: A transmitting wireless transmit/receive unit (Tx WTRU) may receive configuration information that indicates one or more parameters. The one or more parameters may be associated with resource selection. The Tx WTRU may determine a first resource selection window and a second resource selection window. The first resource selection window may be associated with an active time of a receiving wireless transmit/receive unit (Rx WTRU). The second resource selection window may be associated with an inactive time of the Rx WTRU. The Tx WTRU may determine a first number of candidate resources associated with the first resource selection window. The Tx WTRU may determine a first number of candidate resources associated with the second resource selection window. In examples, the Tx WTRU may increase the first number of candidate resources associated with the first resource selection window to a second number of candidate resources associated with the first resource selection window.

Abstract: Systems, methods, and instrumentalities are disclosed for narrowband (NB) LTE operation. A WTRU may receive a first downlink data transmission, for example, via a physical downlink shared channel (PDSCH). The WTRU may determine to send a hybrid automatic repeat request (HARQ) acknowledgment (ACK) in response to receipt of the first downlink data transmission. The WTRU may transmit a first uplink reference signal. The WTRU may indicate the HARQ-ACK using a first cyclic shift index that is applied to the first uplink reference signal. The WTRU may determine to send a HARQ negative ACK (HARQ-NACK), for example, on a condition that a second downlink data transmission is not correctly received. The WTRU may send a second uplink reference signal. The WTRU may indicate the HARQ-NACK using a second cyclic shift that is applied to the second uplink reference signal.

Abstract: Procedures, methods, architectures, apparatuses, systems, devices, and computer program products are disclosed that may be implemented in a wireless transmit/receive unit (WTRU) that is in communication with a base station and/or an intelligent reflecting surface (IRS). For example, the WTRU may operate to facilitate selection of a first beam transmitted from the base station and reflected by the IRS and selection of a reflection parameter set which configures the IRS to reflect the first beam in a manner which may enhance reception of the first beam at the WTRU. As another example, the WTRU may operate to facilitate selection of a beam pair which may include a first beam transmitted from the base station and a second beam transmitted from the base station and reflected by the IRS to the WTRU. The WTRU may receive a configuration which associates particular beams with particular reference signal resources.

Abstract: A method performed by a transmit/receive point (TRP) for enhancing transmission reliability may include transmitting information indicating at least a first constellation to be used for modulating a transmission. The method includes transmitting, in a first time interval, a first repetition of a data payload. The transmitted first repetition of the data payload includes a set of coded bits that is modulated according to the indicated constellation. The method includes transmitting, in a second time interval, a second repetition of the data payload. The first time interval is a slot within a repetition window and the second time interval is a later slot within the repetition window. The second repetition includes a set of coded bits that is modulated according to a second constellation. The first constellation and the second constellation may be different and vary respectively based on repetition indices corresponding to the first repetition and the second repetition.

Abstract: Methods and systems are described herein for bandwidth part (BWP) operation in 5G wireless systems. A wireless transmit/receive unit (WTRU) may be configured to receive a physical downlink control channel (PDCCH) transmission on a first BWP associated with a first carrier. The PDCCH transmission may include scheduling information for receiving a physical shared downlink channel (PDSCH) transmission via a second BWP associated with a second carrier. The WTRU may be configured to determine one or more quasi co-located (QCL) parameters for the PDSCH transmission using a lowest transmission configuration indication (TCI) state associated with the second BWP associated with the second carrier based on a scheduling offset of the PDSCH transmission being less than a threshold and on the PDSCH transmission being received via the second BWP. The WTRU may be configured to receive the PDSCH transmission using the determined one or more QCL parameters.

Abstract: A wireless transmit/receive unit (WTRU) may be configured to measure a downlink quality associated with at least one first beam. The WTRU may be configured to determine whether the measured downlink quality associated with the at least one first beam is below a threshold value. The WTRU may be configured to receive at least one control channel transmission using a determined second beam, based on, in part, a determination that the measured downlink quality associated with the at least one first beam is below the threshold value. The determined second beam used to receive the at least one control channel transmission may be a same beam that is used to receive an associated data channel transmission. The determined second beam may be from a set of beams. The set of beams may be received via higher layer signaling.
