  • Publication number: 20250007596
    Abstract: Embodiments include methods for a user equipment (UE) configured to communicate with a radio access network (RAN) via a master cell group (MCG) and a secondary cell group (SCG). Such methods include, while the SCG is deactivated, performing beam failure detection (BFD) for at least one cell in the SCG, according to a first BFD configuration. Such methods include, in response to detecting an initial beam failure in the deactivated SCG, transmitting a first message indicating the initial beam failure to a RAN node configured to provide the MCG; and in response to detecting one or more subsequent beam failures in the deactivated SCG, refraining from transmitting to the RAN any messages indicating the one or more subsequent beam failures (e.g., until receiving another BFD configuration). Other embodiments include complementary methods for a RAN node, as well as UEs and RAN nodes configured to perform such methods.

  • Patent number: 12184563
    Abstract: A method by a master network node for measurement gap configuration includes establishing a connection with a wireless device operating in dual connectivity with the master network node and a secondary network node. The master network node operates on a New Radio, NR, wireless network and the secondary network node operates on a Long-Term Evolution, LTE, network. The measurement gap configuration is configured on a per frequency basis for at least a first frequency and a second frequency on the NR wireless network. The measurement gap configuration is configured on a per frequency basis for the first frequency on the LTE network. The method further incudes configuring, by the master network node, the wireless device with at least one measurement gap for the second frequency when the master network node configures a measurement that requires the at least one measurement gap.
