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.

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 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, method, and device for ensuring a number of Phase Tracking Reference Signal(s) (PT-RSs) are the same for multiple slots. A wireless transmit/receive unit (WTRU) may receive control information including a number of scheduled resource blocks (RBs) then determine a PT-RS density based on the number of scheduled RBs. The WTRU may determine a RB offset value for the WTRU based on a WTRU-ID modulo the maximum RB offset value, where the maximum value for the RB offset value may be based on at least one of the number of the scheduled RBs and the PT-RS density. The WTRU may then transmit or receive a signal with PT-RS based on the RB offset value.

The WTRU may receive downlink control information (DCI), and the DCI may include an indication of 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 control information in a physical shared channel transmission using the determined one or more physical shared channel frequency resources during the determined time period. Also, the control information may include a WTRU-identifier (ID) associated with the WTRU. In an example, the control information may include a new data indicator (NDI) or a retransmission of previously transmitted control information. In a further example, the physical shared channel transmission may further include data.
