  • Publication number: 20250055490
    Abstract: This application sets forth techniques for mitigating radio frequency (RF) interference from wired connections on cellular wireless reception quality, including pre-emptively determining when to perform RF interference mitigation based on various factors. An interference mitigation module in the wireless device determines whether to perform an interference mitigation procedure based on active and/or imminent use of a high-speed wired connection port for data transfer in parallel with a cellular wireless connection that uses a mid-frequency RF band or a high-frequency RF band. The wireless device determines a target cell in a low-frequency RF band and biases measurement reports sent to a cellular wireless network to handover and keep the cellular wireless connection to the target cell in the low-frequency RF band while a high-speed wired connection is active.

  • Patent number: 11991772
    Abstract: Systems and methods for extending connectivity with a cellular network are disclosed herein. A UE may monitor a serving cell of the UE and a neighbor cell of the UE to determine whether there is a network condition wherein the UE is to transition to an out-of-service (OOS) state if it were to fall to a Radio Resource Control (RRC) Idle state. The UE may react by, before expiration of an inactivity period corresponding to a transition to an RRC Idle mode, initiating signaling activity with a radio access network (RAN) node of the serving cell. In other embodiments, the UE may determine, based on a number of secondary devices connected to the UE, to initiate signaling with the RAN node of the serving cell before expiration of an inactivity period and according to whether a maximum number of extensions of an extension activity period has been reached.

  • Publication number: 20230370966
    Abstract: The present application relates to improving a roaming service. In an example, user equipment (UE) initiates a cell selection process to choose between a first cell and a second cell. The UE evaluates a first uplink (UL) channel condition of the first cell and a second UL channel condition of the second cell based on the initiation. The UE selects the first cell or the second cell based on the evaluated first UL channel condition and second UL channel condition. The UE initiates a random access channel (RACH) procedure based on the selected first cell or second cell.
