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: Embodiments of the present disclosure relate to discontinuous reception (DRX) transmission. Embodiments of the present disclosure propose a solution for DRX configurations for point-to-point (PTP) and/or point-to-multipoint (PTM) transmissions. In this solution, a user equipment (UE) maintains separate DRX configurations for PTP transmissions and PTM transmissions. During active time for the PTP transmissions, the UE monitors physical downlink control channel (PDCCH) with a UE specific identifier. The UE monitors PDCCH with a PTM transmission specific identifier during active time for the PTM transmissions. In this way, it can match the MBS service quality mechanism. Moreover, it also saves power at the UE.

Abstract: The exemplary embodiments relate to a computer-readable storage medium, a device, an integrated circuit and a method that perform operations related to a first user equipment (UE) configured with a sidelink (SL) connection with a second UE. The operations include generating an SL counter check request including at least a first count for data transmissions from the first UE to the second UE as determined by the first UE. The operations further include transmitting the request to the second UE and receiving a counter check response to the request, the response comprising at least a second count for data transmissions from the first UE to the second UE as determined by the second UE. The operations further include determining a first difference between the first count and the second count and, when the first difference exceeds a threshold, releasing the SL connection with the second UE.

Abstract: An approach to reduce the signaling overhead for tracking reference signal (TRS) configuration signaling to idle and inactive user equipments (UEs) operating in a wireless communication system. Conventional signaling approaches require more bits that can be conveyed in the maximum system information block (SIB) message size. One proposed approach optimizes the signaling by removing unnecessary or redundant information, using a single TRS configuration to replace multiple configurations, size reduction in some fields, and the sharing of some fields across different TRS configurations. Another proposed approach uses an SIB message to carry the TRS configurations for a particular beam or subset of beams. These two proposed approaches may be combined to provide further optimization possibilities.

Abstract: A user equipment (UE) may be barred from accessing one or more network slices. The UE collects information to perform an access barring procedure corresponding to a cell of a network, performs an accessing barring procedure using the information, performs a random access channel (RACH) procedure with the cell and establishes a radio resource control (RRC) connection with the cell.
