  • Patent number: 11871346
    Abstract: This disclosure relates to using a wake up signal in conjunction with cellular communication in unlicensed spectrum. A cellular base station may provide a wake up signal on an unlicensed frequency channel after successful completion of a listen-before-talk procedure. The wake up signal may include a preamble configured for coherent detection, and information indicating channel occupancy time for a cellular communication by the cellular base station and a cell identifier for the cellular base station. A wireless device may monitor the unlicensed frequency channel for a wake up signal, and may determine whether to monitor the unlicensed frequency channel for control channel signaling based on whether a wake up signal is received, and potentially also based on the contents of the wake up signal if a wake up signal is received.

  • Patent number: 11792599
    Abstract: A device, e.g. a wireless communication device may obtain information associated with private cellular networks from a provisioning server. The information may provide an indication of coverage area(s) of available private cellular network(s). The device may communicate over a commercial cellular network, and determine, based at least on the information, whether the device is located within the coverage area of any available private cellular networks. The device may connect to a first private cellular network (FPCN) of the available private cellular networks and switch from communicating over the commercial cellular network to communicating over the FPCN at least in response to the determination indicating that the device is located within the indicated coverage area. The device may disconnect from the FPCN in response to a determination that the signal level of the FPCN is below a specified value and the device is not using a wallet garden application.

  • Patent number: 11737118
    Abstract: This disclosure relates to providing system information for cell access to link budget limited devices. According to some embodiments, a base station may transmit a master information block (MIB), a first system information block (SIB), and second SIBs. The first SIB and the second SIBs may be configured for different device categories, and may accordingly have different characteristics. For example, the first SIB may be configured for link budget limited devices, and may include information specific to such devices and/or may exclude information not relevant to such devices or not critical to accessing the cell. In some instances, the first SIB may also include information from the MIB, such that at least some devices may be able to decode the first SIB and gain cell access without decoding the MIB.

  • Publication number: 20220386246
    Abstract: A user equipment (UE), or other network component can operate to generate new radio (NR) communications in millimeter wave (mmW) frequencies. Body proximity sensing (BPS) operations can be performed to determine whether a maximum permissible exposure (MPE) event is triggered. A safe transmit power level associated with the one or more bands can then be used to provide the NR communications. Additionally, determinations of whether various conditions are satisfied to suspend the BPS operations for a period can be evaluated and implemented. The BPS can be configured such that a BPS period of the BPS operations are aligned with a discontinuous reception (DRX) cycle at a beginning of a DRX on-duration of a DRX cycle, wherein the one or more conditions comprise a DRX idle time or state.

  • Patent number: 11490293
    Abstract: Re-connecting to a first radio access network (RAN) of a first radio access technology (RAT) may include initially connecting to the first RAN. A connection associated with a voice call may then be connected that includes connecting to a RAN of a second RAT. In response to the voice call connecting to the second RAN, information for both a frequency and a cell associated with connecting to the first RAN may be stored. An end to the voice call may be identified. In response to determining that the voice call has ended, a timer may be generated at the UE that comprises a specified time period and the timer and the information stored for both the frequency and the cell associated with connecting to the first RAN may be utilized to re-connect to the first RAN.

  • Patent number: 11375420
    Abstract: This disclosure relates to techniques for a link budget limited UE to improve communications performance with a cellular network. The UE may perform signal to interference noise ratio (SINR) measurements and use these measurements to adjust a received signal power value that is provided to the cellular network as a received signal power measurement. The UE may generate the received signal power value based at least in part on the SINR measurement in order to reduce the likelihood of handover when the UE has good SINR but poor received signal power. The UE may also provide preferred configuration information to the base station which enhances the performance of the UE when link budget limited. The configuration information may specify one or more parameter values designed to provide improved performance for a link budget limited device.
