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: 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 a set of subcarriers from two physical resource blocks (PRBs). The set of subcarriers includes only one subcarrier or more than two subcarriers. The processor is further configured to transmit, using the first set of antenna ports of the transceiver, channel state information reference signals (CSI-RSs) in a set of resource elements (REs) to the second UE. The set of REs occupies the set of subcarriers.

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: Some aspects of this disclosure relate to apparatuses and methods for implementing techniques for providing a user equipment (UE) with on-demand reference signals for location related measurements of the UE. The UE can receive location assistance data from a network server, where the location assistance data includes information about a plurality of downlink reference signals that can be used to perform location related measurements by the UE. The UE can send a request to a base station for a reference signal. The reference signal is selected from the plurality of downlink reference signals of the location assistance data. Furthermore, the UE can receive the reference signal from the base station, and perform a location related measurement based on the received reference signal.

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.

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.
