Abstract: Systems and methods for using a relay user equipment (UE) to transport data of interest received from a first remote UE to a second remote UE on a UE to UE relay within a wireless communication system are discussed herein. These methods may be performed at Layer 2 of a protocol stack of the wireless communication system. Data packets sent on the UE to UE relay may include an adaptation header including routing information (e.g., Layer 2 addresses, a bearer-specific index, etc.) for the UE to UE relay. An adaptation layer may accordingly be provided within Layer 2 to decode these adaptation headers. In some cases, a per-bearer approach may be used to map between individual direct bearers of a hop by hop path configuration of the UE to UE relay. Embodiments eschewing the adaptation header and instead using logical channel identifiers (LCIDs) to make routing indications are also described.

Abstract: A user equipment (UE) may be configured with information to perform conditional handovers or addition/change of a primary secondary cell (PSCell). The UE receives a first radio resource control (RRC) configuration message from the source cell for conditional handover to the at least one target cell, the first RRC configuration message including conditional handover execution conditions, an RRC configuration and a target cell ID for each one of a list of target cells, performs measurements on the target cells to determine whether any one of the target cells fulfills its corresponding conditional handover execution conditions and, when a first target cell from the list of target cells fulfills its corresponding conditional handover execution conditions, initiates a handover to the first target cell.

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 base station serves as a positioning node for locating a user equipment (UE). The base station receives information from a network component indicating the UE is transmitting positioning sounding reference signals (SRS), monitors for the positioning SRS based on, at least, the information and when positioning SRS are received from the UE, transmits SRS information to the network.

Abstract: A user equipment (UE) is configured to enter a radio resource control (RRC) CONNECTED state on a first network using a first subscriber identification module (SIM) and an RRC INACTIVE or RRC IDLE state on a second network using a second SIM, transmit, to the first network, a request for a scheduling gap (SG) configuration, wherein, during a duration of the SG, the first network avoids scheduling resources for the UE, receive, from the first network, an indication of the SG configuration to be used, during the duration of the SG, tune away from the first network to perform operations on the second network and after the duration of the SG, tune back to the first network, wherein the RRC CONNECTED state is maintained on the first network during the duration of the SG.

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: Aspects are described for a user equipment (UE) comprising a transceiver configured to enable wireless communication with a base station and a second UE, and a processor communicatively coupled to the transceiver. The processor is configured to determine one or more channel state information (CSI) reporting elements out of a set of CSI reporting elements. The processor is further configured to generate a MAC control element (MAC-CE) message. The MAC-CE message comprises an indicator that indicates a second MAC-CE message and a CSI report. The CSI report comprises the one or more CSI reporting elements. The processor is further configured to transmit, using the transceiver, the MAC-CE message to the second UE via a side-link connection.
