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: 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 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: Systems and methods are provided for controlling behavior for overriding grants for channel state information (CSI) feedback. A user equipment (UE) may control override of a first grant of a first radio resource by a second grant of a second radio resource. The UE determines that the second radio resource at least partially overlaps with the first radio resource. The UE also determines a physical layer priority of the first grant of the first radio resource and the second grant of the second radio resource. The physical layer priority is based on at least one of the first grant of the first radio resource and the second grant of the second radio resource being configured for transmitting CSI feedback over a physical uplink shared channel (PUSCH) to a base station. The UE then generates a transmission according to the physical layer priority.

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.
