  • Patent number: 11405914
    Abstract: Techniques are described that provide for waveform selection for uplink (UL) and/or downlink (DL) wireless transmissions based on one or more factors associated with the wireless transmission, a transmitter that is to transmit the wireless transmission, or combinations thereof. UL and DL transmissions may use one of a number of different waveforms, such as single-carrier waveforms that use a single carrier for information transmission of a wireless channel, and multi-carrier waveforms that use multiple carriers at different frequencies to transmit some of the bits on each channel. Multi-carrier transmission waveforms or single-carrier waveforms may be selected for wireless transmissions based on a bandwidth allocated for the transmissions, a capability of a transmitter that is to transmit the transmissions, or combinations thereof.

    Abstract: A system for a tag includes a network controller that, when it has information to send to a tag, is configured to communicate with the tag's neighbors, such as anchors that may be used for communication between the tag and the network controller. In this regard, the network controller may instruct the tag's neighbors to stun the tag upon hearing from the tag. Thus, when the tag transitions out of a sleep state and transmits a status message or other type of message to the network controller or other resource of the network, at least one neighbor of the tag hears the message and, in response, stuns the tag so that it remains awake for a longer period of time, thereby giving the network controller sufficient time to send control information or other information to the tag. Since the neighbors are responsible for stunning the tag, the amount of time required to stun the tag after it awakens from the sleep state is decreased.

  • Patent number: 11343769
    Abstract: Methods and systems for wirelessly transmitting data between Wi-Fi stations without requiring the Wi-Fi stations to be fully connected to the Wi-Fi network. A first Wi-Fi station generates the data to be transmitted. The data comprises status data and/or wake-up data. The first Wi-Fi station then inserts the data in a vendor-specific information element of a probe request frame and wirelessly transmits the probe request frame. The probe request frame is then received by a second Wi-Fi station. If the probe request frame contains wake-up data and the second Wi-Fi station is operating in a low-power mode when it receives the probe request frame, the second Wi-Fi station will wake-up from the low-power mode. If the probe request frame contains status data then the second Wi-Fi station may process the probe request frame and/or forward at least a portion of the received probe request frame to another device.

  • Patent number: 11343766
    Abstract: Example methods for indicating downlink service data and devices are described. One example method includes controlling, by a first station (STA) associated with a radio access point (AP), a wake-up receiver of the first STA to wake up within a preset first listen interval. The first STA receives a wake-up beacon frame sent by the AP, and controls main radio (MR) of the first STA not to wake up within a second listen interval to receive a beacon frame sent by the AP. According to the method provided in this application, the MR of the first STA does not need to wake up within the second listen interval to receive the beacon frame broadcast by the AP.
