摘要： Apparatuses, systems, methods, and computer program products to save power in peer-to-peer communication devices associated with wireless communication networks are disclosed. Embodiments generally comprise wireless communications devices. A device may associate or connect with an access point and communicate with another device also connected to the access point. The devices may establish a direct link as part of a tunneled direct link system (TDLS) network. After establishing the direct link, the devices may negotiate a wakeup schedule, enabling both devices to enter power saving modes to conserve power. The devices may maintain the direct link while in power saving modes, enabling the devices to periodically exit the power saving modes and transfer buffered data.

摘要： Disclosed is a tunneling mechanism that enables frames generated by a MAC layer management entity (MLME) to be transmitted by another. By doing that, a pair of stations (STAs) can perform functions such as (re)association, authentication, and the like, without having to transmit frames over-the-air but, instead, use a different MLME for this purpose. This enables the station management entities (SMEs) of a pair of multi-band capable STAs to provide a seamless fast session transfer (FST), including the provisioning of multi-band (de)authentication and (re)association.

摘要： Methods and systems for communicating in a wireless network may distinguish different types of packet structures by modifying the phase of a modulation constellation, such as a binary phase shift keying (BPSK) constellation, in a signal field. Receiving devices may identify the type of packet structure associated with a transmission or whether the signal field is present by the phase of the modulation constellation used for mapping for the signal field. In one embodiment, the phase of the modulation constellation may be determined by examining the energy of the I and Q components after Fast Fourier Transform. Various specific embodiments and variations are also disclosed.

摘要： Embodiments provide a new short beacon frame format and its operation with full beacon frame transmissions for wireless communications devices. Many embodiments comprise a medium access control (MAC) sublayer logic to build frames comprising the short beacon frame for a first communications device. In some embodiments, the MAC sublayer may determine a frame control field comprising a type field indicative of an extension frame and a subtype indicative of a short beacon. In further embodiments, the frame control field may comprise a service set identifier (SSID) control field, and a reserved field. Some embodiments may store the short beacon frame or frame format in memory, in logic, or in another manner that facilitates transmission of the short beacon frames. Some embodiments may receive and detect communications with the short beacon frames. Further embodiments may generate and transmit a communication with the short beacon frames.

摘要： Various embodiments are disclosed for techniques to perform channel access decisions and to select a transmit queue. These decisions may be performed, for example, based upon the age and number of packets in a queue. These techniques may allow a node to improve the length of data bursts transmitted by the node, although the invention is not limited thereto.
