摘要： Apparatuses may stay synchronized with a network via a beacon signal transmitted at a set interval. Communication-related activities may be planned around instances when beacon signals are expected, which may also be known as a target beacon transmission time (TBTT). Scanning opportunities, which are periods of time during which apparatuses may perform passive scanning, may be planned based on an interfere multiple of a network beacon signal interval. Apparatuses may, upon realizing a scanning opportunity,opt either to utilize the scanning opportunity or to participate in network beaconing. In example scenarios where apparatuses opt to utilize scanning opportunities, apparatuses may prepare a network information message and then enter a passive scanning mode. Apparatuses may remain in the passive scanning mode for the duration of the scanning opportunity,reacting when messages are received from devices outside of the network by transmitting the network information message.

摘要： Service discovery for services on a wireless network is presented. It is determined (e.g., from a received Layer 2 message) that an offering apparatus has made a service available to entities joined to a wireless network. Then in a message, that is available to entities not joined to the network, is placed information about the services and also at least one of location information about the offering apparatus and link metric information about a network path to the offering apparatus. A discovering apparatus reads one or more transmitted messages (from different apparatuses in the same network in different networks), sees the service it wants is available through both, compares the different locations and/or the different link metrics, and based on the comparing chooses which network to join, or with which apparatus on the single network to create a peer link.

摘要： There are a plurality of power saving modes for a device in a wireless network. It is determined that the device is using one of the power saving modes on a peer-specific link, a state is set to indicate that the device is using that specific power saving mode, and a message is transmitted to the peer over the link that includes an indication of the state. There may also be a power management indication that indicates whether a Ml power state is in use of one of the power saving modes are in use. Exemplary power saving modes are light sleep and deep sleep. A method, apparatus, and computer readable medium are detailed, and exemplary environments may be practices in or by a WLAN mesh point.

摘要： Various embodiments are disclosed relating to techniques for RTS/CTS usage in a wireless network 102. According to an example embodiment, a network performance may be measured within a wireless network 102. A variety of parameters may be measured at a wireless node 106 to determine a network performance. In addition, it may be determined 220 whether the network performance has reached a degraded performance threshold. A frame is transmitted via the wireless network 102. If the network performance has reached the degraded performance threshold, the frame may be transmitted using a Request-to-Send/Clear-to-Send (RTS/CTS) protection. In another example embodiment, a frame may be transmitted 230 using RTS/CTS protection if an estimated transmission time for the frame exceeds a transmission time threshold.

摘要： The invention relates to a method for decreasing power consumption in a wireless terminal intended for a short-range wireless communication system. In the method the standard MAC functionality of a wireless terminal is modified so that packet transaction times become shorter thus reducing the power consumption and giving the terminal more time for the power save mode. This is accomplished by increasing the transmission rate of physical layer data units comprising a preamble, a header, and a payload portion so that the header is transmitted at a transmission rate higher than what is standardized for the header. The transmission rate of the header is preferably increased to the highest transmission rate standardized for the payload portion. In further embodiments of the invention further modifications of the MAC functionality are introduced, the embodiments further decreasing the packet transaction times.
摘要翻译：本发明涉及一种用于降低用于短距离无线通信系统的无线终端的功耗的方法。在该方法中，修改无线终端的标准MAC功能，使得分组交易时间变短，从而降低功耗并给予终端更多的节电模式时间。这是通过增加包括前同步码，报头和有效载荷部分的物理层数据单元的传输速率来实现的，以便以比标题标准化的传输速率更高的传输速率发送报头。报头的传输速率优选地增加到为有效载荷部分标准化的最高传输速率。在本发明的另外的实施例中，引入了MAC功能的进一步修改，该实施例进一步减少了分组交易时间。
