Methods and apparatus for wireless transmit/receive unit (WTRU) power control
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.

3 . The WTRU of claim 1 , wherein the WTRU is in active time when the ON duration is started, and wherein the processor and the transceiver are further configured to decode at least one PDCCH transmission when the WTRU is in active time.
4 . The WTRU of claim 3 , wherein the second set of CSI reports is sent during the ON duration outside of active time.
5 . A method, implemented in a wireless transmit/receive unit (WTRU), the method comprising:
receiving a configuration for discontinuous reception, wherein the configuration comprises information associated with an ON duration;
determining a plurality of DRX cycles based on the configuration, wherein a start of each respective DRX cycle corresponds to a start of a respective ON duration;
receiving a signal before the start of the respective ON duration; and
determining to send, during the respective ON duration, reports, wherein the reports are: (1) a first set of channel state information (CSI) reports, on a condition that the signal is received with a first value; or (2) a second set of CSI reports, on a condition that the signal is received with a second value,
wherein the second set is a subset of the first set.
6 . The method of claim 5 , wherein the signal is received on a physical downlink control channel (PDCCH).

wherein the processor and the transceiver are configured to receive, during the respective ON duration, a first set of channel state information (CSI) reports, on a condition that the signal is sent with a first value,
wherein the processor and the transceiver are further configured to receive, during the respective ON duration, a second set of CSI reports, on a condition that the signal is sent with a second value, and
wherein the second set is a subset of the first set.
