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: Some aspects of this disclosure relate to apparatuses and methods for implementing sidelink communications among multiple user equipments (UEs). A UE operates according to a periodical discontinuous reception (DRX) cycle that includes a sidelink on-duration period when the UE is in an active state. The UE is in a power saving state outside the sidelink on-duration period. The UE listens to a Physical Sidelink Control Channel (PSCCH) for sidelink communications during the active state. A UE determines the DRX cycle and the sidelink on-duration period of a receiver UE, and sends a message to the receiver UE during one or more slots of the sidelink on-duration period when the receiver UE is in the active state.

Abstract: A device, system and method for a user equipment (UE) to report a network resource and capability state to a network for coordinating network resource allocations. The UE is configured to establish a first connection to a first network based on a first subscriber identity module (SIM) of the UE and further configured to establish a second connection to a second network based on a second SIM of the UE. The method includes determining an upcoming first change of a state of the UE with respect to the first connection and transmitting, to the first network, an indication of the first change of state of the UE. The method further includes changing the state of the UE with respect to the first connection.

Abstract: SL-DRX involves both Uu and PC5 interfaces. For an RRC_CONNECTED UE (also referred to as a connected mode UE, or simply connected UE), several SL-DRX enhancements are described in this disclosure to trigger SL DRX and share configurations. Alignment of SL-DRX alignment with Uu-DRX (referred to as Uu/SL DRX alignment or simply alignment) is also described, as an optional feature (since not all schedules can temporally align).

Abstract: This disclosure provides details of a configuration signaling and associated behaviors for sidelink (SL) discontinuous reception (DRX) for unicast, connection-specific DRX. According to one embodiment, a first user equipment (L E) configures link-specific discontinuous reception (DRX) by processing a common DRX configuration that is preconfigured, received through a Uu interface, or received in a SIB; and signaling over a PCS interface with a second UE, a link-specific configuration for a link-specific DRX cycle, the Link-specific configuration including a link-specific on-duration parameter.
