  • Patent number: 9525539
    Abstract: Embodiments of a multi-transceiver wireless communication device and methods for adaptive multi-band communication are generally described herein. In some embodiments, the multi-transceiver wireless communication device is configurable for half-duplex operation and for asymmetrical full-duplex operation on two non-interfering channels. In some embodiments, a contention-based channel access procedure may be performed to attempt to gain access to both a primary channel and an auxiliary channel. A primary transceiver and an auxiliary transceiver may be configured for asymmetrical full-duplex operation when access to both the primary channel and the auxiliary channel is granted. One of the transceivers may be configured for half-duplex operation when access to only one of the channels is granted.

  • Patent number: 9526029
    Abstract: Logic may compress wireless communications frames and communicate compressed frames that do not include the duplicative bit sequences within the packet flow. Logic may include the compressed frames in flow frames. Logic may generate, encode, transmit, decode, parse, and interpret flow frames after a packet flow is created. Flow frames may comprise a flow frame control field, a compressed frame, and a frame sequence check. Logic may decompress the compressed flow frame based upon flow decompression rules associated with a flow index of the flow frame. Flow frames may include a duration field to set the network allocation vectors of other stations. And the frame sequence check may be generated based upon the entire flow frame.

  • Patent number: 9503249
    Abstract: Disclosed in some examples are methods, systems, and machine readable mediums which allow for wireless devices with limited echo cancellation capabilities to participate in full-duplex communications. In some examples, by carefully controlling transmission powers and the modulation and coding schemes (MCS) used in the transmissions, both devices can engage in full-duplex communication.

  • Patent number: 9426832
    Abstract: Logic to coordinate communications of wireless communications devices to attenuate collisions, such as through coordination of communications by implementing slot logic in an access point. The slot logic may determine a time slot schedule for beacon intervals and may further transmit a synch frame at the time slot boundaries. If the channel is busy, the slot logic may not send the synch frame. The slot logic may also comprise distribution logic to determine a probability of collisions and to instruct one or more of the devices to spread out their channel accesses across beacons intervals to reduce the chance of collisions. A station associated with the access point may comprise synch logic to wake up at a slot boundary and wait for a synch frame or any other packets to synch to the medium.

  • Publication number: 20160234838
    Abstract: Logic may coordinate communications of different types of wireless communications devices such as high power and low power wireless communications devices. Logic may coordinate communications by assigning time slots to a low power station (LP-STA) in a management frame such as a beacon transmitted by an access point (AP) associated with the LP-STA. Logic of the high power stations (HP-STAB) may receive the beacon and shepard logic of the HP-STA may defer transmissions by the HP-STA throughout the duration(s) indicated in the beacon from the AP. Logic of the LP-STA may comprise carrier sense multiple access with collision avoidance logic to determine when to transmit a communication. Shepard logic of an HP-STA may detect the communication from the LP-STA and defer transmission of communication during a time duration for the communication by the LP-STA.

  • Patent number: 9345045
    Abstract: Logic may comprise hardware and/or code to coordinate communications of wireless communications devices. Logic coordinate communications in an access point by implementing adaptive delays. Logic may determine a delay for stations awaking from a doze state during which the station should perform clear channel assessment prior to transmitting packets on a channel. Logic may collect information about devices and/or communications within a basic service set (BSS) such as the statistics of the received packets length in time, the type of stations in the network, and/or other information available. Based upon the information collected, the logic may determine a delay and transmit the delay to devices in the BSS. Logic may receive and update the delay in memory and then implement the delay after switching to an awake state from a doze state.

  • Patent number: 9313086
    Abstract: A System and method for creation and transport of flows. The method includes transmitting an ADDFLOW request to a receiver to add the flow to the wireless network. The method also includes receiving a response message indicating that the flow will be added to the wireless network and delivering the flow to the wireless network. A given flow may be uniquely identified by the concatenation of a flow ID and a flow address. The flow address will always be either the transmitter's or receiver's MAC address. This method could be extended to compress any bit sequences that take on only a limited set of values.

  • Patent number: 9307056
    Abstract: Generally, arrangements for enabling direct medium access control (MAC) sublayer data frames are described herein. Embodiments may comprise logic such as hardware and/or code to reduce the size of a packet by determining a frame in the MAC sublayer, inserting the frame in the signal field of a preamble to transmit, transmitting the direct MAC data frame as a packet, communicating that the packet is a direct MAC data frame, and parsing and interpreting the direct MAC data frame at the receiving device. Embodiments may determine and transmit and/or receive and interpret direct MAC data frames.

  • Publication number: 20150029933
    Abstract: Embodiments may implement a new hierarchical data structure for traffic indication mapping to facilitate transmissions for wireless communications devices. Many embodiments comprise MAC sublayer logic to generate and transmit management frames such as beacon frames with a partial virtual bitmap based upon the hierarchical data structure for traffic indication mapping. In some embodiments, the MAC sublayer logic may store the traffic indication map and/or the traffic indication map structure in memory, in logic, or in another manner that facilitates transmission of the frames. Some embodiments may receive, detect, and decode communications with frames comprising the partial virtual bitmap based upon the hierarchical data structure. In some embodiments, indications of buffered data for pages, blocks, sub-blocks, and/or stations may be inverted. In several embodiments, a new association identifier (AID) structure is defined for the new hierarchical data structure for traffic indication mapping.
