This disclosure describes systems, methods, and devices related to a time division duplex (TDD) antenna sector switch. A device may determine one or more antenna sector configurations based on TDD beamforming, wherein the one or more antenna sector configurations are associated with first antenna sectors used to communicate with a first station device (STA). The device may initiate a TDD sector switch with the first STA to switch from the one or more first antenna sectors to one or more second antenna sectors. The device may cause to send, to the first STA, an action frame comprising TDD sector setting parameters associated with the TDD sector switch. The device may identify a response frame received from the first STA, wherein the response frame comprises the TDD sector setting parameters. The device may perform the TDD sector switch by switching from the one or more first antenna sectors to the one or more second antenna sectors.

This disclosure describes systems, methods, and devices related to link aggregation between devices. A device may determine a first frequency band and a second frequency band for sending data to a second device in a multiband link aggregation session. The device may cause to send, in an initial state, a setup request frame to the second device for establishing the multiband link aggregation session. The device may receive, in a setup completion state, a setup response frame from the second device to establish the multiband link aggregation session. The device may cause to send, in an operating mode established state, the data to the second device over the first frequency band and/or the second frequency band in the multiband link aggregation session.

This disclosure describes methods, apparatus, and systems related to media access control (MAC) range extension. A device may cause to append a training field to each of one or more beacon frames. The device may cause to send the one or more beacon frames directionally using a sector sweep to one or more responder devices during a first interval. The device may determine an extended schedule element to be sent to the one or more responder devices, the extended schedule element including one or more directional antenna sectors to be used by the device during a second interval. The device may identify a first frame from a first responder device, during the second interval, wherein the first frame is received on a directional antenna sector of the one or more directional antenna sectors corresponding to an operating sector of the first responder device.

A system and method are provided for implementing unique multi-band service discovery protocols between communicating devices, including wireless communicating devices supporting operations according to multiple standards and in different frequency bands, particularly in peer-to-peer or ad hoc networking schemes. The disclosed systems and methods define within each service discovery frame, whether a service discovery query or a service discovery response, an indication of the frequency band and/or channel that may support a specific service indicated by the service discovery frame. Cooperating communicating devices between which communications are to be established supporting a specific service protocol are provided with a mechanism by which to identify which common frequency bands and/or channels the communicating devices may communicate in executing the specific service.

A system and method are provided to implement dynamic spectrum access with individual multi-mode devices that incorporate multiple radios in a single device. A multi-mode device is configured to make use of the incremental spectrum by maintaining a data communication link via a base station that is operated by a primary operator to support communications in the primary operator's exclusively-licensed spectrum. This data communication link is maintained by a first radio, the data communication link being used to support a first level of data communication as well as to signal an availability of additional spectrum to the multi-mode device. The multi-mode device may request access to additional spectrum. A second radio may facilitate access to received additional spectrum with the multi-radio multi-mode device.

This disclosure describes methods, apparatus, and systems related to providing a source device more degrees of freedom in the performing CCA, and in using CCA for communicating with neighboring devices. Before accessing the channel, a source device may need to perform carrier sense multiple access with collision avoidance (CSMA/CA), the CSMA/CA additionally comprising CCA. In various embodiments, CCA can be performed either using quasi-omnidirectional receiving antenna(s), or using directional receiving antenna(s). In one embodiment, one or more requisite conditions for performing directional CCA can be specified. In another aspect, sensitivity level adjustments can be provided when performing directional CCA and/or quasi-omnidirectional CCA.

Certain embodiments herein are directed to enabling service interoperability functionality for wireless fidelity (WiFi) Direct devices connected to a network via a wireless access point. A WiFi Direct device may identify various other WiFi Direct devices on a WiFi network for performing a requested service, such as printing content or displaying content to a screen. In so doing, the device may share information associated with an access point to which the device is connected with the other devices, which may also share information associated with an access point to which they are connected. In this way, WiFi Direct devices may discover their connectivity with respect to other devices to utilize a broader array of connection options for implementing a desired service, and hence, may leverage application programming interface (API) modules directed at providing service interoperability functionality between software applications and services requested by the software applications.

Apparatuses, systems, and methods that enable native MAC support of beamforming are contemplated. An embodiment may comprise a mobile computing device, such as a laptop, with wireless communications capabilities, such as an integrated wireless networking card. The networking card of the laptop may transmit and receive various types of frame data using one or more beamforming techniques. Upon establishing a link with another wireless device, the laptop may sense that the link quality is degrading. Instead of having to reestablish a new link using dedicated BF frames and the conventional BF protocol, embodiments described herein may instead transmit beamforming information in various types of frames which enable the wireless communication devices to adjust the beamforming parameters in a more efficient manner. For example, the devices may include beamforming information in control frames and data frames and transmit the frames in a sweeping sector fashion.

Techniques to enable dynamic bandwidth management at the physical layer level while maintaining backwards compatibility in wireless systems is provided. Furthermore, techniques for reducing the occurrence of exposed nodes are provided. A transmitter may transmit a frame including an indication that a PHY layer sub-header defining a bandwidth associated with a channel is present. Furthermore, the transmitter may transmit a third frame after receiving a second frame from a receiver to indicate to legacy stations that the TXOP was successful.
