  • Patent number: 10326615
    Abstract: A device for facilitating cellular-wireless local area network (WLAN) interworking may include at least one processor circuit. The processor circuit may be configured to receive a packet including a first tunnel identifier and addressed to a user equipment (UE). The processor circuit may be configured to identify a radio bearer associated with the first tunnel identifier, where the radio bearer is configured to facilitate transmission of the packet to the UE via cellular communications. The processor circuit may be configured to determine whether the radio bearer has been offloaded over a WLAN. The processor circuit may be configured to, when the radio bearer has been offloaded over the WLAN, identify a second tunnel identifier mapped to the radio bearer; encapsulate the packet based on the second tunnel identifier, where the encapsulated packet includes the second tunnel identifier; and transmit the encapsulated packet to the UE over the WLAN.

  • Publication number: 20190174325
    Abstract: In some aspects, the disclosure is directed to methods and systems for coexistence management. A first access point is scheduled a time to begin transmission of a packet to a user device in an unlicensed frequency band using a first RAT. The time to begin the transmission is scheduled to avoid transmission overlap with a second access point using a second RAT in the unlicensed frequency band, and scheduled according to information from the second access point regarding operation in the unlicensed frequency band using the second RAT. One of the first and second RATs includes one of a WLAN RAT or a LTE based RAT, and another of the first and second RATs includes a remaining one of the WLAN RAT or the LTE based RAT, in one or more embodiments. The first access point receives updated information regarding operation in the unlicensed frequency band using the second RAT.

    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: 10153815
    Abstract: Mixed mode operations within multiple user, multiple access, and/or MIMO wireless communications. Certain communication systems can include wireless communication devices of various capabilities therein (e.g., IEEE Task Group ac (TGac VHT), IEEE 802.11 amendment TGn, IEEE 802.11 amendment TGa, and/or other capabilities, etc.). In one manner of classification, wireless communication devices having legacy and newer/updated capabilities may inter-operate with one another, operate within a common region, and/or communicate via a common access point (AP). Coordination of such wireless communication devices (e.g., legacy and newer/updated) provides for their respective operation on a same set of clusters in accordance with various operational modes including: (1) time dividing medium access between the wireless communication devices of various capabilities, (2) assigning primary cluster(s) for a first capability set and assigning non-primary cluster(s) for a second capability set, etc.

  • Publication number: 20180279333
    Abstract: In some aspects, the disclosure is directed to methods and systems for coexistence management. A first access point operating in an unlicensed frequency band using a first RAT receives, from a second access point operating in the unlicensed frequency band using a second RAT, information regarding operation of the second access point in the unlicensed frequency band. It is determined, using the received information, that the first access point or the second access point is using a first share of the unlicensed frequency band that is below a predetermined threshold, indicating an imbalance of usage between the first RAT and the second RAT. A transmission parameter of the first access point for operating in the unlicensed frequency band using the first RAT is adjusted according to the determination.

  • Publication number: 20180242394
    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: 10004074
    Abstract: Transmission coordination within multiple user, multiple access, and/or MIMO wireless communications. Within wireless communication systems, there can be various wireless communication devices therein that are not all compliant with a common capability set, communication protocol, communication standard, recommended practice, etc. For example, some communication systems may have some wireless communication devices characterized as ‘legacy’ wireless communication devices, and other wireless communication devices therein may be newer and compliant with newer capability sets, communication protocols, communication standards, recommended practices, etc. In such instances, coordination of transmissions among the various wireless communication devices may be made, when performing simultaneous transmissions, by ensuring that transmissions of devices on different channels is made when aligned on a common boundary of an OFDM symbol.
