摘要： A wireless transceiver includes an antenna array that transmits an outbound RF signal containing outbound data to remote transceivers and that receives an inbound RF signal containing inbound data from the remote RF transceivers, wherein the antenna array is configurable based on a control signal. An antenna configuration controller generates the control signal to configure the antenna array to hop among a plurality of radiation patterns based on a hopping sequence. An RF transceiver section generates the outbound RF signal based on the outbound data and that generates the inbound data based on the inbound RF signal. In one configuration, a switching section selectively couples a selected one of the antennas in the array to the RF transceiver section, based on the control signal. In another configuration, the RF transceiver section includes an RF section for each antenna in the array.

摘要： Mechanism to mitigate signal interference in ultra wide band (UWB) networks based on spatial reuse of the signal spectrum. Efficient media access control (MAC) in wireless networks is challenging because wireless devices may be affected by signal interference during spatial multiplexing. Wireless ad-hop (multi-hop) networks exploit the limited system bandwidth available via spatial reuse to enhance aggregate throughput. Spatial reuse allows concurrent data exchanges, resulting in higher throughputs.

摘要： Aspects of a method and system for scheduling multiple concurrent transmissions during a contention access period in a wireless communications network are presented. Aspects of the system comprise communicating devices (DEVs) within a piconet that are operable to derive a neighborhood map of a piconet. The neighborhood map information may enable a plurality of DEVs to concurrently transmit signals during a given channel time allocation (CTA) time slot. The ability for multiple DEVs to transmit signals concurrently during a single CTA time slot may increase spectral reuse within a wireless communication medium. In another aspect the system, the neighborhood map information may enable individual DEVs to set clear channel assessment (CCA) thresholds. Individual DEVs may utilize CCA threshold information to determine when to transmit signals to one or more destination DEVs and/or at what rate to transmit data via the signals.
摘要翻译：提出了一种用于在无线通信网络中的竞争访问周期期间调度多个并发传输的方法和系统的方面。系统的方面包括可微微网内的通信设备（DEV），其可操作以导出微微网的邻域图。邻域图信息可以使多个DEV在给定的信道时间分配（CTA）时隙期间同时发送信号。在单个CTA时隙期间多个DEV同时传输信号的能力可以增加无线通信介质内的频谱重用。在另一方面，系统中，邻域图信息可以使得各个DEV可以设置明确的信道评估（CCA）阈值。单独的DEV可以利用CCA阈值信息来确定何时向一个或多个目的地DEV发送信号和/或以何种速率通过信号发送数据。
