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 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: Methods and systems for transmitting uplink control information in an LTE Advanced system are disclosed. A user device may determine whether uplink control information and/or available channels meet certain criteria and determine whether the uplink control information should be transmitted on a physical uplink control channel, a physical uplink shared channel, or both, based on the criteria. Criteria may include the size of the uplink control information (absolute size or relative to space available on a channel or a threshold value), the type of control information bits, the number of available (i.e., active or configured) component carriers, and the amount of power that may be required to transmit the uplink control information on more than one channel.

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: 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: 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.

Abstract: A wireless transmit/receive unit (WTRU) may receive assignment information for receiving a first codeword using a first modulation and coding scheme (MCS) in a first set of resource blocks (RBs), and a second codeword using a second, different MCS in a second set of RBs. The first and second sets of RBs may be in a first time interval in a first bandwidth part using a first subcarrier spacing. The WTRU may receive, in symbols of the first time interval in the first bandwidth part, the first codeword using the first MCS in the first set of RBs and the second codeword using the second, different MCS in the second set of RBs. At least a portion of the first codeword and at least a portion of the second codeword may be received in at least a first symbol in the symbols in the first time interval.

Abstract: Methods and apparatus for burst transmission are provided. A wireless transmit/receive unit (WTRU) is configured to receive configuration information for a periodic search space (P-SS) and a semi-persistent search space (SP-SS). The configuration information may include a monitoring periodicity of the P-SS and a monitoring periodicity of the SP-SS. The P-SS may be associated with the SP-SS. The WTRU is configured to monitor the P-SS with the periodicity of the P-SS. The WTRU is configured to receive a first message in a first physical downlink control channel (PDCCH) in a slot of the P-SS. The first message may indicate an activation of the associated SP-SS. The WTRU is configured to monitor the SP-SS using the periodicity of the SP-SS. The WTRU is configured to receive a second message in a second PDCCH in a slot of the SP-SS.
