  • Patent number: 10405189
    Abstract: In a shared radio frequency (RF) band, regulations or standards can stipulate that a device using an RF channel must vacate the RF channel if another device having priority to the channel is detected. It takes time, however, to move channels and this added time reduces the effective speed of the communication. In some cases, a received signal from the other device may be received on the channel when the other device is not, in fact, operating on the channel. These received signals can lead the device to move channels, thereby slowing communications unnecessarily. Accordingly, disclosed herein are a system and method for checking the characteristics of a received signal's spectrum to determine if the source of the received signal is on-channel or off-channel. This determination may be used to minimize the device from taking unnecessary interference avoidance measures, such as dynamic frequency selection.

  • Patent number: 10405368
    Abstract: A mobile communications device is configured to implement dual connectivity, using both a Long-Term Evolution (LTE) radio and a 5th-Generation (5G) radio, for communicating with respective base stations of a cellular network. A primary transmission uplink is established in a first radio frequency band using the LTE radio. The device may then receive a request to establish a secondary transmission uplink in a second frequency band. Upon receiving the request, the device determines whether it can support concurrent use of the primary and secondary frequency bands while maintaining adequate receiver sensitivity. If the device cannot support such concurrent use, the device refuses the request. In addition, the device provides data indicating the degree by which certain performance parameters would be out-of-tolerance if the secondary connection were to be established.

  • Patent number: 10397947
    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: 10200952
    Abstract: The present invention provides a wireless access point control method, a related device, and a system. An activation signal sent by user equipment is received on a radio resource corresponding to a receiving pattern of a first wireless access point, so that the first wireless access point controls itself to leave a power-saving state according to the activation signal. Therefore, the user equipment may directly send the activation signal to the first wireless access point to switch a working state of the first wireless access point from the power-saving state to a normal communication state as soon as possible. In this manner, a power-saving objective of the wireless access point is achieved, and switching of the wireless access point from the power-saving state to the normal communication state as soon as possible can also be accelerated on a basis of achieving power saving of the wireless access point.

  • Patent number: 10143007
    Abstract: A method and apparatus for signaling the release of a persistent resource in long term evolution (LTE) are disclosed. An indication of the release of a downlink (DL) persistent resource is received by a wireless transmit receive unit (WTRU) from an evolved Node-B (eNB) via a physical downlink control channel (PDCCH). A positive acknowledgement (ACK) is transmitted by the WTRU which denotes that the indication has been received. The PDCCH or a medium access control (MAC) CE may be used by the eNB to signal the indication. At least one bit may be added to contents of the PDCCH to signal whether the PDCCH is for DL persistent or dynamic resource allocation. The DL persistent resource is then released and an indication that the DL persistent resource has been released is transmitted.
