  • Patent number: 12256258
    Abstract: Methods for communicating a Quality of Experience (QoE) measurement are provided. In embodiments disclosed herein, a wireless device communicates the QoE measurement to a base station based on Radio Resource Control (RRC) segmentation. In this regard, the wireless device receives an indication that indicates whether the base station can support the RRC segmentation. Accordingly, the wireless device transmits the QoE measurement to the base station based on the RRC segmentation if the indication indicates that the base station can support the RRC segmentation. By transmitting the QoE measurement based on the RRC segmentation, the wireless device can communicate more QoE information to the base station in a larger QoE measurement file (e.g., 8000 kilobytes).

  • Patent number: 12213003
    Abstract: Systems and methods are disclosed herein that enable a wireless communication device (WCD) and/or a network node to perform a recovery action(s) when a failure occurs during reception, at the WCD, of a segmented Radio Resource Control (RRC) message. Embodiments of a method performed by a WCD are disclosed. In one embodiment, a method performed by a WCD comprises receiving one or more segments of a segmented RRC message and determining that an error has occurred before a last segment of the segmented RRC message has been received. The method further comprises, upon determining that the error has occurred before the last segment of the segmented RRC message has been received, performing one or more recovery actions. In this manner, a situation where the WCD combines segments of a first RRC message with segments of a second RRC message is avoided and, hence, errors due to such combining are avoided.

    Abstract: Embodiments herein may relate to a method performed by a UE (10) for determining a start position of a SI window to acquire a SI message in a wireless communication network (1). One or more SI messages are scheduled using a first or a second list of scheduling information. The UE (10) determines, if the SI message is scheduled using the first list of scheduling information, the start position of the SI window based on a location of the SI message in the first list of scheduling information. The UE (10) determines, if the SI message is scheduled using the second list of scheduling information, the start position of the SI window by taking a received input parameter into account, wherein the received input parameter is indicating the start position of the SI window used for acquiring the SI message.

  • Publication number: 20240414589
    Abstract: A first network node is configured for handling communication in a wireless communications network. Based on logical channel information configured at the first network node, the first network node determines a version of a buffer status report to use. For example, the version of the buffer status report to use may be determined from among multiple buffer status report versions, where two or more of the multiple buffer status report versions each support multiple logical channel groups, LCGs, e.g., a first version that supports up to 8 LCGs and a second version that supports up to 256 LCGs. Regardless, the first network node transmits the buffer status report of this determined version to a second network node.
