  • Patent number: 11490246
    Abstract: In an embodiment, a network component (e.g., eNB) of a terrestrial wireless communication subscriber network determines whether a drone-coupled user equipment (UE) is engaged in a flying state based upon one or more wireless signals transmitted by the drone-coupled UE. The determination can occur in a variety of ways, such as based on a message from the drone-coupled UE itself (e.g., an express flying-state notification from the drone-coupled UE, a request particular to a flying state, a measurement reporting message, an identifier used by the drone-coupled UE, uplink signal strength measurement(s) or uplink AoA measurements, whether any intervening base station(s) were skipped over in conjunction with a handoff of the drone-coupled UE, etc.).

  • Publication number: 20220338159
    Abstract: Methods, systems, and devices for wireless communications are described. In some examples, a user equipment (UE) may receive, from a network node, a paging message indicating information for communication between the network node and the UE. In some examples, the UE may receive, from a network node, a downlink alert message indicating a paging message for subsequent transmission to the UE. The UE may identify a delay based on receiving the paging message or the downlink alert message, a measurement of a communication link satisfying a threshold, or any combination thereof. The UE may establish an uplink connection with the network node based at least in part on an expiration of the delay. The UE may communicate the information using the uplink connection.

  • Patent number: 11477708
    Abstract: Methods, systems, and devices for wireless communications are described that provide for a user equipment (UE) to report packet switched voice call capabilities to a base station. The UE may explicitly report voice call capabilities via one or more system-level parameters that are transmitted to the base station. The base station may operate in a first radio access network (RAN), such as a 5G or new radio (NR) RAN. In cases where the UE indicates a capability for packet switched voice calls via the first RAN, one or more voice calls may be established with the UE via the first RAN. In cases where the UE indicates that it is not capable of packet switched voice calls via the first RAN, the UE may fall back to a different RAN (e.g., a 4G or LTE RAN, a 3G RAN, or a 2G RAN) for voice calls.

  • Publication number: 20220322331
    Abstract: The base station may receive a first indication that the UE supports NR-CA with multiple PUCCH groups or NR-DC with multiple cell groups and a second indication that the UE does not support simultaneous Rx/Tx in a first frequency band and a second frequency band, and schedule communication with the UE to avoid scheduling the simultaneous Rx/Tx based on the first and second indications. The base station may avoid scheduling simultaneous Rx/Tx in a first cell group or a first PUCCH group including the first frequency band and a second cell group or a second PUCCH group including the second frequency band. The UE may skip reporting to the base station that the UE supports the NR-DC or the NR-CA with the first frequency band and the second frequency band.

  • Publication number: 20220303882
    Abstract: This disclosure provides systems, methods, and apparatus, including computer programs encoded on computer storage media, for operating a user equipment (UE) in a next generation (NG) radio access network (RAN) (NG-RAN) to validate a system information block (SIB) for non-public networks (NPNs). In one aspect, a UE receiving a SIB-one (SIB1) from a cell of the NG-RAN may determine whether the cell supports non-public networks (NPNs) based on the received SIB1. If so case, the UE may determine whether an NPN-identifier (NPN-ID) in the received SIB1 matches an NPN-ID of a SIB stored in memory. If so, the UE may validate the stored SIB based at least in part on the received SIB1. If not, the UE may invalidate the stored SIB and obtain a new SIB per standard procedures.
