摘要： Adverse effects associated with collisions in a wireless communication system are mitigated by defining one or more values for receive data. Here, data that is expected to be received during a data transmission may be set to a defined value. In some cases the defined value is a predefined value (e.g., zero or some other value). In some cases the defined value is based on noise and/or signals levels in the system. In some implementations a device may define receive data values for a period of time during which data is expected to be received and during which a transmission occurs. In some aspects a hybrid on-off keying scheme is employed to determine received data values.

摘要： An apparatus for data communication that receives a plurality of pulses from a remote communications device, determines a pulse puncturing rate based on the pulses, and punctures or discards subsequent pulses based on the pulse puncturing rate. During intervals when punctured pulses are expected, the apparatus operates in a lower power consumption mode for the purpose of conserving power. In another aspect, a receiving apparatus determines the pulse puncturing rate based on received pulses, and transmits the pulse puncturing rate information to a transmitting apparatus. In response, the transmitting apparatus sends a subset of the pulses it would have transmitted based on the pulse puncturing rate. Because the receiving apparatus receives fewer pulses (e.g., a subset), the receiving apparatus may operate in a lower power consumption mode for longer periods in order to conserve power. Similarly, because the transmitting apparatus sends fewer pulses, it may also operate in a lower power consumption mode for longer periods.
摘要翻译：一种用于从远程通信设备接收多个脉冲的数据通信装置，基于脉冲确定脉冲打孔速率，并且基于脉冲打孔速率对后续脉冲进行穿刺或丢弃。在期望脉冲脉冲的间隔期间，为了节省功率，该装置以较低的功耗模式工作。在另一方面，接收装置基于接收到的脉冲来确定脉冲打孔速率，并将脉冲打孔速率信息发送到发送装置。作为响应，发送装置基于脉冲打孔速率发送其将发送的脉冲的子集。由于接收装置接收到更少的脉冲（例如，子集），所以接收装置可以在较低的功耗模式下操作更长的时间段，以便节省功率。类似地，由于发送装置发送较少的脉冲，所以它也可以在较低的功耗模式下工作较长时间。

摘要： In a two-way ranging scheme where a first apparatus (e.g., device) determines a distance to a second apparatus (e.g., device), specified packets are sent between these apparatuses at specified times to facilitate the determination of the distance. In some aspects, these packets may be defined and/or sent in a manner that enables the apparatuses to detect a leading edge of a received packet with a high degree of accuracy. For example, an apparatus may transmit a packet a defined period of time after transmitting or receiving another packet. In addition, a packet may comprise a defined symbol sequence that is used by an apparatus that receives the packet to identify a leading edge of the packet.

摘要： A channel access scheme is provided for a pulse-based ultra-wide band network. Here, concurrent ultra-wide band channels may be established through the use of a pulse division multiple access scheme. An access scheme may employ different states each of which may be associated with different channel parameter state information and/or different duty cycles. For example, a channel access scheme may employ an inactive state, an idle state, a connected state, and a streaming state. Multiple logical channels may be defined for a given ultra-wide band channel via, for example, pulse division multiplexing.
