    • Examples are disclosed for providing flexible clear channel assessment (CCA) detection thresholds in a wireless local access network (WLAN). In some examples, an apparatus for dynamically setting a clear channel assessment (CCA) threshold in a wireless local area network (WLAN) may comprise a processor component, a radio coupled to the processor component, and logic for execution by the processor component to establish a CCA threshold for a wireless channel of the WLAN, send a first wireless message to one or more wireless station (STA) devices in wireless proximity to the apparatus informing the one or more STA devices of the established CCA threshold and instructing the one or more STA devices to avoid CCA levels exceeding the CCA threshold on the wireless channel and send a second wireless message to a wireless access point (AP) device associated with the apparatus informing the AP device of the established CCA threshold and instructing the AP device to broadcast use of the CCA threshold on the wireless channel. Other examples are described and claimed.

    • Logic such as hardware and/or code to narrow available sub-channels in frequency selective transmission communications in which a station selects a narrow band from a wider channel bandwidth. A frequency selective transmission scheme for communications devices may select a 1 or 2 MHz channel from a wider channel bandwidth (e.g., 4, 8, 16 MHz) that consists of a number of 1 or 2 MHz sub-channels and transmitting packets on the selected sub-channel. The access point may narrow the number of sub-channels available for selection by stations. Stations may narrow the number of sub-channels. Both the AP and the stations may operate to narrow the number of sub-channels. A medium access control sub-layer protocol common to the communications devices may facilitate a frequency selective transmission scheme.
    • 诸如用于在频率选择性传输通信中缩小可用子信道的硬件和/或代码的逻辑,其中站从更宽的信道带宽选择窄带。 用于通信设备的频率选择性传输方案可以从由多个1或2MHz子信道组成的较宽信道带宽(例如,4,8,16MHz)中选择1或2MHz信道,并在所选择的信道上传输分组 子频道 接入点可以缩小可用于站点选择的子信道的数量。 车站可能会缩小子频道的数量。 AP和站都可以操作以缩小子信道的数量。 通信设备公用的介质访问控制子层协议可以促进频率选择性传输方案。

    • 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.
    • 实施例可以实现用于业务指示映射的新的分层数据结构,以便于无线通信设备的传输。 许多实施例包括MAC子层逻辑,用于基于用于业务指示映射的分层数据结构来生成和发送诸如具有部分虚拟位图的信标帧的管理帧。 在一些实施例中,MAC子层逻辑可以将存储器中的业务指示映射和/或业务指示映射结构存储在逻辑中,或以促进帧的传输的另一种方式存储。 一些实施例可以基于分层数据结构来接收,检测和解码与包括部分虚拟位图的帧的通信。 在一些实施例中,页面,块,子块和/或站的缓冲数据的指示可以被反转。 在几个实施例中,针对业务指示映射的新的分层数据结构定义了新的关联标识符(AID)结构。
