Abstract: Devices, methods, and systems for coverage extension. A bundle of repeated transmissions of a preamble are transmitted responsive to a reference signal received power (RSRP) being less than a threshold and a random access (RA) procedure being initiated. A random access response (RAR) window is monitored for a random access radio network temporary identity (RA-RNTI) corresponding to the repeated transmissions of the preamble.

In some implementations, each of the repeated transmissions of the preamble comprises a preamble index that is different from preamble indices of others of the repeated transmissions of the preamble. In some implementations, the spatial filter comprises a transmission (Tx) beam. In some implementations, the bundle of repeated transmissions of the preamble comprises retransmissions of a msg1.

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.

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.
