  • Publication number: 20200296594
    Abstract: Systems and methods provide reliable voice connections and highest possible data rates in New Radio dual-connectivity environments, given limitations of available spectrum. A system includes a first wireless station and a second wireless station. The first wireless station provides a shared spectrum of a first frequency band, the shared spectrum including a first spectrum for a first cellular wireless standard and a second spectrum for a second cellular wireless standard. The second wireless station is at least partially within a coverage area of the first wireless station and provides a third spectrum for the second cellular wireless standard. The third spectrum is a millimeter wave (mmWave) spectrum. The first wireless station broadcasts cell parameters barring an end device in an idle mode from camping on the second spectrum. The first wireless station or the second wireless station triggers the end device to swap to the second spectrum when a paging request for a voice call is received.

  • Patent number: 10548029
    Abstract: A user device receives system information block data from a cell. The user device obtains, from the system information block data, cell metadata that includes a cellular parameter. The user device parses the cell metadata to identify the cellular parameter. The cellular parameter includes an upper layer indicator element, a public land mobile network (PLMN) information list element, and a network capability indicator element. The user device determines, based on the cellular parameter, that the cell is of a particular cell type of a plurality of cell types, and that the cell has a particular capability of a plurality of types of capabilities. The user device performs an action based on the particular cell type or the particular capability.

  • Publication number: 20200015162
    Abstract: A device may receive signal information associated with a wireless signal or charge information associated with a charge level. The signal information may indicate a signal strength of the wireless signal. The charge information may indicate the charge level of a battery of the device. The device may determine whether the signal strength or the charge level satisfies a threshold. The device may configure a parameter or a setting of the device to cause the device to operate according to a long term evolution (LTE) category based on determining whether the signal strength or the charge level satisfies the threshold. The LTE category may be different from a default LTE category of the device and may define an uplink/downlink capability specification. The device may attach to a network in association with configuring the parameter or the setting to cause the device to operate according to the LTE category.
