  • Patent number: 11229024
    Abstract: A wireless communication system for minimum allocation includes an access point (AP) and a number of stations (STAs) communicating with the AP via a network such as a wireless local area network. The AP can identify an STA to which a trigger frame is to be sent by the AP. The AP further determines the amount of resources to be provided by the AP to the identified STA through the trigger frame. The AP can also determine a frequency of sending the trigger frame to the STA. The resources can include a frequency allocation, a time duration and a modulation coding scheme. The time duration is a maximum receive (RX) physical-layer convergence protocol (PLCP) protocol data unit (PPDU) duration.

  • Patent number: 11165542
    Abstract: A wireless communication device (alternatively, device) includes a processor configured to support communications with other wireless communication device(s) and to generate and process signals for such communications. In some examples, the device includes a communication interface and a processor, among other possible circuitries, components, elements, etc. to support communications with other device(s) and to generate and process signals for such communications. A device generates and transmits a resource and association poll frame (ra-poll frame) to other device(s). The contents of ra-poll frame direct which of the other device(s) is authorized to respond to the device (e.g., authorized device(s)) and the manner in which they are authorized to respond. Authorized device(s) transmit responses that may include association request(s) and/or a resource request(s), among other types of communications.

  • Patent number: 11089652
    Abstract: Coordination and synchronization is performed between two or more wireless network managers (e.g., access points (APs)). A first wireless network manager supports first communications with first other wireless communication devices, and a second wireless network manager supports second communications with those first and/or second other wirelessly case devices. The first and second wireless network managers also support communications with one another to coordinate the first and second communications supported with the first and/or second other wireless communication devices. Examples of coordination include selection of which other wireless communication devices are serviced or in communication with which of the first and second wireless network managers, selection of operational parameters (e.g., modulation coding set (MCS), beamforming, frequency band assignment, channel assignment, scheduling information, transmit power, etc.

  • Patent number: 11013033
    Abstract: A wireless communication device (alternatively, device) includes a processing circuitry configured to support communications with other wireless communication device(s) and to generate and process signals for such communications. In some examples, the device includes a communication interface and a processing circuitry, among other possible circuitries, components, elements, etc. to support communications with other wireless communication device(s) and to generate and process signals for such communications. A device receives a request to send (RTS) from another device and replies with a clear to send (CTS) when the RTS includes a non-zero-valued network allocation vector (NAV) if one or more conditions make such a response permissible. The device processes other parameter(s) associated with other communications between other devices to determine if a CTS response is permissible even during the other communications between the other devices.

  • Patent number: 10944518
    Abstract: A wireless communication device (alternatively, device, WDEV, etc.) includes at least one processing circuitry configured to support communications with other WDEV(s) and to generate and process signals for such communications. In some examples, the device includes a communication interface and a processing circuitry, among other possible circuitries, components, elements, etc. to support communications with other WDEV(s) and to generate and process signals for such communications. The WDEV generate a first orthogonal frequency division multiple access (OFDMA) frame that specifies information regarding resource unit (RUs) to be used by other WDEV. The WDEV transmits the first OFDMA frame to other WDEVs and receives a second OFDMA frame from the WDEVs based on some RUs specified within the first OFDMA frame. The WDEV then generates and transmits a third OFDMA frame to the other WDEVs (e.g., based on RU(s) spanning RU(s) within which information is received in the second OFDMA frame).

  • Patent number: 10805002
    Abstract: A wireless communication device is implemented to include a communication interface and a processor. The processor is configured to process communications associated with the other wireless communication devices within the wireless communication system to determine one or more traffic characteristics of those communications as well as one or more class characteristics of the other wireless communication devices. The processor is configured to classify the communications into one or more access categories based on the one or more traffic characteristics and is configured to classify the other devices into one or more device class categories based on the one or more class characteristics. The processor is then configured to generate one or more channel access control signals based on these classifications. The communication interface of the device is configured to transmit the one or more channel access control signals to one or more of the other devices.

  • Patent number: 10554354
    Abstract: A communication device includes a processor configured to generate OFDMA packets using various OFDMA packet structures and to transmit such OFDMA packets, via a communication interface, to at least one other communication device. The processor is also configured to receive, interpret, and process such OFDMA packets. One example of an OFDMA packet includes common SIG for two or more other wireless communication devices modulated across all sub-carriers of the OFDMA packet. The common SIG is followed by first SIG and first data for a first other wireless communication device modulated across first subset of the sub-carriers of the OFDMA packet and is also followed by second SIG and second data for a second other wireless communication device modulated across second subset of the sub-carriers of the OFDMA packet. Another example of an OFDMA packet includes the common SIG followed directly by first data and second data modulated as described above.

  • Patent number: 10433250
    Abstract: Time division multiple access (TDMA) media access control (MAC) adapted for single user, multiple user, multiple access, and/or MIMO wireless communications. Various com systems may include smart meter stations (SMSTAs) and/or wireless stations (STAs). Appropriate coordination is made with respect to such communication devices to ensure appropriate uplink (and/or downlink) communications between a network manager or coordinator (e.g., an access point (AP)) and the SMSTAs and/or STAs. With respect to SMSTAs, the relative duration of time that such communication devices are awake and operative versus asleep (or in a reduced power and/or functionality state) can be significant. Certain implementations may include a relatively large number of such communication devices (e.g., 10s, 100s, 1000s, or more), and appropriate coordination and scheduling of such communications to/from them is made using one or more variations of TDMA signaling (e.g.

In some examples, the device includes a communication interface and a processing circuitry, among other possible circuitries, components, elements, etc. to support communications with other WDEV(s) and to generate and process signals for such communications. A WDEV generates and transmits a first signal that includes a field that specifies an acceptable interference level (AIL) for concurrent communication for use by a first other WDEV to determine whether a transmission from the first other WDEV to a second other WDEV acceptably or unacceptably interferes with another transmission from the WDEV. Concurrent communication (e.g., from the WDEV to a third other WDEV, and from the first other WDEV to the second other WDEV) may be made when the AIL compares favorably with the AIL.
