  • Patent number: 11178543
    Abstract: A device that identifies entry into a new service area, transmits a service area update request to a network device associated with a network, receives a control plane message from the network indicating control plane device relocation or a key refresh due to a service area change in response to transmitting the service area update request, and derives a first key based in part on data included in the control plane message and a second key shared between the device and a key management device. Another device that receives a handover command from a network device associated with a network, the handover command indicating a new service area, derives a first key based on data included in the handover command and on a second key shared between the device and a key management device, and sends a handover confirmation message that is secured based on the first key.

  • Patent number: 11171813
    Abstract: Techniques for blind distributed multi-user MIMO enable simultaneous decoding of multiple concurrent wireless transmissions without the need for coordination between wireless devices or a measurement phase. Wireless devices are permitted to transmit independently and at arbitrary times. Concurrent transmissions from wireless devices superimpose in the wireless channel and are received at various base stations. The base stations forward received data samples to a central entity (e.g., a cloud computing service), which uses known preambles to reliably estimate CFOs and channels between the transmitting devices and the receiving base stations while simultaneously recovering the data samples of the individual data streams.

  • Patent number: 11172409
    Abstract: A wireless communication network (12) includes one or more nodes (10, 40) that individually or cooperatively prevent affiliated communication modules (14) from being handed over at the same time. Affiliated communication modules (14) provide a machine, device, or other entity (16) with redundant access to the network (12) and preventing the simultaneous handover of affiliated communication modules (14) within the network (12) reduces the chance that the involved entity (16) will lose radio connectivity or experience an interruption in its communications. Although not limited to Critical Machine Type Communication, C-MTC, applications, such operations improve connection redundancy and reliability for C-MTC entities that use two or more communication modules (14) for redundant access to a wireless communication network (12).

  • Patent number: 11172357
    Abstract: In an aspect, a network may support a number of client devices. In such a network, a client device transmits a request to communicate with a network, establishes a security context, and receives one or more encrypted client device contexts from the network. An encrypted client device context enables reconstruction of a context at the network for communication with the client device, where the context includes network state information associated with the client device. The client device transmits a message (e.g., including an uplink data packet) to the network that includes at least one encrypted client device context. Since the network device can reconstruct the context for the client device based on an encrypted client device context, the network device can reduce an amount of the context maintained at the network device in order to support a greater number of client devices.

Subsequently, the UE can search the service from another cell/TA or another PLMN. In one embodiment, if the UE receives reject cause invalidating the UE with one access without integrity protection, the UE tries the system a few times before treating the reject genuine by tracking an invalidating counter, which is increased by one each time the rejection is received with a cause value invalidating the UE.

  • Patent number: 11134514
    Abstract: Example random access methods and apparatus are described. In one example method, a terminal device receives a system message that is sent by a network device on a first downlink carrier. The system message includes first information for performing random access on a first uplink carrier and second information for performing random access on a second uplink carrier. A frequency of the first uplink carrier is higher than a frequency of the second uplink carrier, and a frequency of the first downlink carrier is the same as the frequency of the first uplink carrier. The terminal device sends a random access request message on the first uplink carrier or on the second uplink carrier, and receives a random access response message that is sent by the network device on the first downlink carrier.

  • Patent number: 11134458
    Abstract: A communication technique for synchronizing a set of radio nodes is described. In this communication technique, the radio node arbitrates (e.g., using a precision time protocol or PTP) with the other radio nodes based on a selection technique to select a synchronization master in the set of radio nodes. This synchronization master may be selected to have a predefined performance based on a type of communication environment of the set of radio nodes. For example, the type of communication environment may include overlap between at least one of the radio nodes in the set of radio nodes and a macrocell in a cellular-telephone network, or may exclude overlap between the set of radio nodes and the macrocell. Moreover, the synchronization master may specify time, frequency, and phase synchronization for the set of radio nodes. Thus, when the synchronization master is different from the radio node, the radio node synchronizes with the synchronization master.

  • Patent number: 11129073
    Abstract: A wireless communication network hands-over wireless User Equipment (UE) from a serving cell to a neighbor cell. The serving cell wirelessly exchanges data with the wireless UE and determines uplink interference for a radio band. The serving cell wirelessly transfers an uplink interference offset to the wireless UE that indicates the uplink interference at the serving cell for the radio band. The wireless UE uses the uplink interference offset to trigger a handover request to the serving cell. The handover request indicates downlink signal strength at the wireless UE for the serving cell. The serving cell initiates a handover to a neighbor cell responsive to a combination of the downlink signal strength at the wireless UE and the uplink interference for the serving cell falling below a handover threshold. After the handover, the neighbor cell wirelessly exchanges data with the wireless UE over a different radio band.

  • Patent number: 11122614
    Abstract: Systems and methods of wireless communication in which wireless devices are adapted to implement adaptive waveform selection are disclosed. For example, operation according to embodiments may provide for use of a waveform design that minimizes peak-to-average power ratio (PAPR), such as single-carrier frequency division multiplexing (SC-FDM), as well as a waveform design that provides higher spectral efficiency, such as orthogonal frequency division multiplexing (OFDM), for scenarios that are not power-limited and the higher PAPR is acceptable. Adaptive waveform selection may be based implicitly on one or more parameters or may be based on explicit signaling. Adaptive waveform selection may be utilized with respect to initially establishing a communication link and/or with respect to an established communication link.

  • Patent number: 11115883
    Abstract: Devices, systems, and methods are disclosed for network-controlled UE filtering of detected cell reporting. The network instructs currently-connected UEs to only report neighboring cells that meet network-defined mobility filtering criteria and, in some embodiments, additional non-mobility filtering criteria. In response to receiving such instructions from the network, the UEs will apply the filtering criteria to at least the data associated with neighboring cells and, in some embodiments, data of the UE to determine which of the neighboring cells meet the filtering criteria. Once the UEs have determined that one or more neighboring cells meets the filtering criteria, the UEs communicate a detected cell report back to the network, which, according to specific embodiments of the invention, may be limited to identification of the neighboring cells that meet the mobility filtering criteria and, in some embodiments, additional non-mobility filtering criteria.
