  • Patent number: 12621658
    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.

  • Patent number: 12526864
    Abstract: Peer devices may wirelessly communicate with each other over a bidirectional sidelink logical channel (LCH) through an established bidirectional sidelink radio bearer. An initiating device of the peer devices may dynamically select a logical channel ID for establishing a fully bidirectional or semi-bidirectional SLRB. At least two alternative sidelink radio resource control (PC5-RRC) procedures may ensure the SLRB parameters are configured correctly in the established logical channel. The procedures also allow the network to configure a limited SLRB which is used to couple the SLRB configuration in the direction in which limited traffic (e.g. feedback information such as robust header compression feedback and/or status reports) is transmitted.

  • Publication number: 20250393091
    Abstract: Multi-hop configurations in Integrated Access and Backhaul (IAB) networks are provided for reduced latency. For example, modifications to a backhaul adaptation protocol (BAP) header supports faster data radio bearer (DRB) transmissions. Or, for both signaling radio bearer (SRB) and DRB flows, configuration forwarding may be used to reduce configuration latency wherein a single RRCReconfiguration message is forwarded to intermediate nodes that process the configuration and respond back independently. Alternatively, for both SRB and DRB flows, configuration multi-casting may be used for simultaneous IAB node and backup configurations. Methods are provided for fast activation of backup links in IAB nodes.

  • Patent number: 12403210
    Abstract: Devices and associated methods for operating a dual-subscriber identity module (SIM) dual-standby (DSDS) user equipment device (UE) configured with a first SIM and a second SIM. The UE performs communications with a first cellular network using the first SIM and a first radio resource control (RRC) connection, and receives a request to perform a higher priority communication using the second SIM. In response to the request to perform the higher priority communication, the UE transmits a request to the first network to suspend the first RRC connection. After transmission of the request to suspend the first RRC connection, the UE receives a message from the first network to place the first RRC connection in an inactive state, and initiates a timer, wherein the timer is used to determine whether the first RRC connection remains in the inactive state or transitions to an idle state.

  • Publication number: 20250261284
    Abstract: A user equipment (UE) device may reside in a state of dual connectivity with a master cell group (MCG) and a secondary cell group (SCG), wherein the radio access technologies of the MCG and the SCG are different. While in the dual connectivity state, the UE device may transition to a mode of reduced activity (e.g., processing and/or RF activity) relative to the secondary cell group (SCG) in order to save power, e.g., when traffic flow via the SCG is below a threshold, or when scheduling activity on the SCG is low. Various mechanisms may be employed to reduce activity, e.g., mechanisms such as reduction of beam monitoring, deactivation of secondary cells of the SCG, reduction of number of active antenna elements, employment of longer periods for periodic measurement and reporting processes, etc.
