  • Patent number: 12382284
    Abstract: A user equipment (UE) may attempt to access an edge data network. The UE generates a first credential based on a second credential, the second credential generated for a procedure between the UE and a cellular network, generating an identifier corresponding to the first credential, and generates a multi-access edge computing (MEC) authorization parameter. The UE then transmits an application registration request message to a server associated with an edge data network, the application registration request message including an indication of the first credential, the identifier corresponding to the first credential and the first authorization parameter. The UE then receives an authentication accept message or an authentication reject message from the server associated with the edge data network.

  • Patent number: 12376183
    Abstract: Provided is a method for a user equipment (UE). The UE generates a first information for the UE for transmission to a network device. The first information is associated with a small data transmission (SDT) procedure in an inactive state of the UE. The UE obtains a first configuration information from the network device. The first configuration information is determined with reference to the first information. The UE determines whether to perform the SDT procedure in the inactive state according to the first configuration information. The UE, in response to determining to perform the SDT procedure in the inactive state, performs the SDT procedure in the inactive state according to the first configuration information.

  • Patent number: 12369067
    Abstract: To accommodate a mix of high frequency carriers and lower frequency carriers, a protocol stack may include a radio link control (RLC) entity that allows configuration of status reporting control parameters on per carrier, or per subcarrier spacing. Alternatively, a protocol stack may include two RLC entities, one for handling high frequency carriers, and another for handling lower frequency carriers. (High frequency carriers and lower frequency carriers may be distinguished based on a frequency threshold.) Furthermore, a user equipment may transmit (to the network) an indication of its L2 buffer size. The network may configure the UE and/or control scheduling, to ensure the UE's L2 buffer does not overrun. Alternatively, the UE may indicate that it can support a percentage of a maximum buffer size. The network may configure the UE and/or control scheduling so that the UE's buffer occupancy does not exceed the percentage.

  • Publication number: 20250142604
    Abstract: Techniques, described herein, include solutions for enabling inter-user equipment (UE) coordination (IUC) using media access control (MAC) control elements (CE). A first UE may send an IUC request to a second UE, and the second UE may respond with a MAC CE that includes IUC information. The IUC information may indicated one or more wireless resources that the first UE may use to communicate with the second UE. The IUC information may also include a time-domain validity for wireless resources, which may include one or more durations of time the wireless resources may be used for communication. The first UE may also implement a latency bound during which the second UE is to respond with the IUC information. In some implementations, discontinuous reception (DRX) may be used by the first and second UEs, and DRX active times of the UEs may be modified or configured to facilitate IUC.

  • Patent number: 12273882
    Abstract: An application layer in a device, a service data adaptation protocol (SDAP) layer in the device, and/or a media access control (MAC) layer in the device may determine that wireless communication resources allocated to the device need to be adjusted. The determination may be in response to detecting that a quality of the wireless connection of the device has deteriorated, or it may be based on advance knowledge of information pertaining to an application layer payload in the device. In response to the determination the device may transmit, in a MAC Control Element (MAC CE) to a base station, a request for an adjustment of the allocated wireless communication resources. The adjustment may lead to a temporary boost of resources for a limited period of time or to a persistent update of the allocated wireless communication resources.
