Abstract: Systems, methods, and instrumentalities are described for dynamically determining codewords that are enabled for transmitting a transport block. A WTRU receives DCI associated with an UL grant for an UL transmission. The DCI may comprise one or more indicators associated with a first codeword and a second codeword. The one or more indicators may comprise at least one of a TPMI or an antenna-group indicator. The WTRU may determine, if the one or more indicators associated with the first codeword and the second codeword comprises a TPMI associated with the second codeword, that the first codeword is enabled for transmission and the second codeword is disabled for transmission. The WTRU transmits a transport block associated with the enabled one or more of the first codeword and the second codeword. If the first codeword is enabled, the WTRU transmits the transport block associated with the first codeword.

Abstract: A wireless transmit/receive unit (WTRU) may receive indication information indicating an uplink (UL) configuration and one or more triggering conditions for transmission of UL signals. Based on reception of a deactivation command or fulfillment of a condition for WTRU-triggered deactivation of a secondary cell group (SCG), the WTRU may deactivate the SCG. Based on the UL configuration and the fulfillment of the one or more triggering conditions, the WTRU may transmit the UL signals via the SCG. The WTRU may receive, via a master cell group (MCG), an in-synch or out-of-synch indication for the SCG. Based on the reception of the out-of-synch indication including a timing advance (TA) delta value, the WTRU may update a UL TA towards the SCG based on the TA delta value. Using the updated UL TA towards the SCG, the WTRU may transmit one or more subsequent UL signals via the SCG.

A sum of a first and second power associated with the first and second UL transmission does not exceed the threshold.

Abstract: A wireless transmit/receive unit (WTRU) may be configured to perform early channel state information (CSI) measurement and/or reporting. Early CSI measurement and/or reporting may differ from traditional CSI measurement and/or reporting in that early CSI measurement/reporting may be performed in association with a two or four step random access channel (RACH) procedure. For example, the WTRU may receive a synchronization signal block (SSB). The WTRU may send a first RACH message based on the SSB. The WTRU may receive a random access response (RAR). The RAR may indicate a resource for early CSI measurement. The WTRU may perform measurement of the early CSI resource and send a report. The report may be sent as part of the random access procedure, for example, in a RACH msg3.

It may be determined that the first AIML model category is no longer applicable based on the first configuration. An indication that indicates that the first AIML model category is no longer applicable to the cell may be sent.
