Abstract: A base station is configured to transmit wake-up signals to a user equipment to wake-up the UE to receive a page from the base station. The base station transmits one or more synchronization signals, wherein the synchronization signals correspond to a wake-up signal (WUS) that is to be transmitted to a user equipment (UE) operating in a paging discontinuous reception (DRX) cycle, wherein the paging DRX cycle includes a paging occasion (PO) and transmits the WUS to the UE during a WUS occasion, wherein the WUS indicates whether the UE is to utilize an active mode or a sleep mode during the PO.

Abstract: A user equipment (UE) configured to operate in a radio resource control (RRC) connected state with a network cell, receive an RRC message to release or suspend the RRC connected state, the RRC message including an indication for a tracking reference signal (TRS) or channel state information reference signal (CSI-RS) configuration to use during an RRC inactive or idle state, enter the RRC inactive or idle state and apply the TRS or CSI-RS configuration for performing timing and frequency error estimation for decoding downlink control information.

Abstract: A user equipment (UE) is configured to deactivate/activate a point-to-multipoint (PTM) link of a multicast radio bearer (MRB). The UE receives, from a base station of a wireless network, a multicast radio bearer (MRB) configuration, wherein the MRB includes configuration of a split MRB including a point to multipoint (PTM) link and a point to point (PTP) link, deactivates or activates the PTM link based on the MRB configuration, reestablishes a radio link control (RLC) associated with the PTM link and recovers a packet data convergence protocol (PDCP).

Abstract: A user equipment (UE) is configured to receive a handover command from a source cell, wherein the UE is configured to exchange data with the source cell after the reception of the handover command, perform downlink synchronization acquisition with a target cell while the UE is configured to exchange data with the source cell and transmit an uplink signal to the target cell, wherein the UE stops exchanging data with the source cell after transmitting the uplink signal to the target cell.

Abstract: A multi-universal subscriber identity module (MUSIM) user equipment (UE) is configured to operate in an Radio Resource Control (RRC) inactive state with a first network associated with the first SIM, operate in an RRC connected state with a second network associated with the second SIM, receive a page from the first network, determine that a priority of at least one operation being performed between the UE and the second network is higher than a priority of the page and send a BUSY indication to the first network in response to the page.
