  • Patent number: 12641627
    Abstract: A broadcast service network (separate from a cellular network) includes broadcast service signal (BSS) nodes that broadcast signals to receivers of user equipment (UE). The BSS may provide broadcast service information to user equipment, such as the emergency notifications, even when the user equipment is out of range of the cellular network. Further, the broadcast service signals may provide information that improves the user equipment's search and access time for connecting to the cellular network (e.g., a cellular service station) and/or that assists the user equipment in locating a nearby region of cellular network coverage. In addition, the BSS may be wake-up signals configured to activate the receiver when the receiver is in a sleep or inactive mode. In some embodiments, the BSS may be pointer signals configured to direct the user equipment to a broadcast service channel to receive the broadcast service information.

  • Publication number: 20260129591
    Abstract: The present application relates to devices and components, including apparatus, systems, and methods for measuring serving cell configuration. The user equipment may detect a condition, and based on the condition, it may determine a configuration associated with a set of requirements. The requirements may be associated with determining a maximum transmit power or power back-offs. The UE may determine the maximum transmit power based on the configuration. Based on the maximum transmit power, UE may perform power control or other algorithms to determine the transmit power used to transmit a signal to the network.

  • Patent number: 12563495
    Abstract: A wake-up signal (WUS) network (separate from a cellular network) includes WUS nodes that broadcast WUSs targeting WUS receivers of user equipment (UE). The WUSs may have low frequencies, such as within a television whitespace spectrum. When the cellular network determines that a UE should enter a power saving mode, or when a cellular receiver of the UE enters an idle state, the cellular network may request resources for the UE from a WUS node and activate a WUS receiver of the UE. When the cellular network has data to send to the UE or a threshold time has expired, the cellular network may request a WUS from the WUS network, which broadcasts the WUS that may be received by the UE. If the UE has data to transmit to the cellular network, the cellular network may request that the WUS node stop providing resources to the UE.

  • Patent number: 12549937
    Abstract: An electronic device discussed herein may communicatively couple to a base station. The base station may receive a first paging cycle assignment corresponding to a first subscriber identification module (SIM) card and determine a second paging cycle assignment for use with a second SIM card. The second paging cycle assignment may be generated based on the first paging cycle assignment. The base station may communicate with the electronic device using the second paging cycle assignment. The second paging cycle assignment may guide the base station to transmit data to the electronic device without interrupting a transmission made according to the first paging cycle assignment.

    Abstract: The present application relates to improve the data communications between a user equipment (UE) and a base station. In an example, the UE can indicate, to the base station, its support of pairing an uplink band with a downlink band to define a frequency division duplex (FDD) band. The uplink band can belong to a first frequency band, whereas the downlink band can belong to a second frequency band. The base station can configure the FDD band for the UE in association with a cell. Data communications can accordingly be performed using FDD.

  • Patent number: 12526729
    Abstract: A base station may send an indication of frequency subranges supported by the base station to user equipment, which may respond with an indication of the frequency subranges that are also supported by the user equipment. Additionally, a Spectrum Access System (SAS) controller, using environmental sensing capability sensors, may determine whether non-federal networks are disposed in a coverage area of a base station and neighboring coverage areas. If so, then the SAS may indicate to the base station to send an indication to user equipment in the coverage area to operate using a default power mode. Otherwise, the SAS may indicate to the base station to send an indication to the user equipment to operate using a lower power mode. Moreover, a base station may indicate a regulatory requirement to user equipment using network signaling value of multiple network signaling values corresponding to multiple regulatory requirements of multiple geographical regions.

  • Patent number: 12495370
    Abstract: Embodiments herein provide various apparatuses and techniques that indicate multiple power classes that user equipment may support to a network. The user equipment may support at least a lower power class (e.g., having a lower maximum transmission power) and a higher power class (e.g., having a higher maximum transmission power) to the network. The user equipment may send indications to the network that it supports both the lower power class and the higher power class. If the network/user equipment are in a geographical region associated with regulations limiting transmission power to the lower maximum transmission power, then the network may configure a transmission power characteristic based on the lower power class. If the network/user equipment are in a geographical region associated with regulations limiting transmission power to the higher maximum transmission power, then the network may configure the transmission power characteristic based on the higher power class.

  • Patent number: 12457632
    Abstract: Embodiments disclosed herein relate to techniques for measuring and/or detecting a signal-to-interference ratio (SIR) of a received signal at a user equipment (UE). The received signal may include a desired signal, co-channel interference, adjacent channel interference, and an in-band blocker. The UE may filter (e.g., remove) the various interferences and in-band blocker. The UE may determine or measure a power (or Received Signal Strength Indicator (RSSI)) of the desired signal and a power (or RSSI) of the co-channel interference separately because the desired signal and the co-channel interference overlap in frequency. To do so, the UE may determine a total power of the received signal including the desired signal and co-channel interference. The UE may receive the desired signal again while an uplink transmission is deactivated (and thus without the interference). The UE may then calculate the SIR based on the total power and the power of the desired signal.

  • Publication number: 20250310065
    Abstract: User equipment may transmit and receive wireless signals to and from various communication networks. Furthermore, user equipment may indicate usage capabilities to the various wireless communication networks to enable the user equipment to transmit and/or receive wireless signals to and from at least two different communication networks. In particular, the user equipment may indicate usage capabilities of supporting both Frequency Range 2 (FR2) wireless signals of a fifth generation (5G) network and 7-24 gigahertz (GHz) wireless signals of a sixth generation (6G) network in an intermediate frequency range of the user equipment. The communication network(s) may then configure and/or schedule the user equipment based on the usage capabilities to enable the user equipment to simultaneously or non-simultaneously communicate using both the FR2 wireless signals and the 7-24 GHz wireless signals while preventing interference in the intermediate frequency range of the user equipment.

  • Patent number: 12432663
    Abstract: User equipment may include a transmitter coupled to an antenna to enable the user equipment to transmit data with a communication node and/or a non-terrestrial network. The user equipment may transmit using high power over a period of time such that the transmission power of the user equipment is below an emission threshold. For example, the user equipment may adjust a buffer status report to reduce uplink allocation frequency. In another example, the user equipment may determine a duty cycle and transmit the data using high power based on the duty cycle. In another example, the user equipment may determine a priority of uplink symbols and transmit certain uplink symbols using high power. In this way, the user equipment may transmit using high power and may improve transmission range to the non-terrestrial network and/or a likelihood that transmissions may be received by the network while remaining within the emission threshold.
