摘要： A method and apparatus are described including scanning a channel, generating a report for the scanned channel, transmitting the channel report to an associated access point and receiving a channel assignment responsive to said channel report. Also described are a method and apparatus including scanning a channel, generating a first channel report, receiving a second channel report from an associated client, transmitting the first channel report and the second channel report to a server, receiving a channel assignment message from the server responsive to the first and second channel reports and transmitting the channel assignment message to the associated client. Further described are a method and apparatus including receiving a channel report from an associated access point, building an interference graph responsive to the channel report, determining channel assignments based on the interference graph and transmitting a channel assignment message to the associated access point.

摘要： A method and apparatus are described including multicasting a medium reservation message and receiving a response to the medium reservation message. Also described are a method and apparatus including receiving a medium reservation message, determining if a medium is idle and transmitting a response to the medium reservation message responsive to the determination. Further described are a method and apparatus including receiving a medium reservation message, determining if a received network allocation vector in the medium reservation message has a value greater than a current network allocation vector, determining if transmission over a medium during a time interval is detected and resetting the current network allocation vector responsive to the determination of transmission. Yet further described are a method and apparatus including receiving a response to a medium reservation message, determining if a network allocation vector in the response is greater than a current network allocation vector and updating the current network allocation vector responsive to the determination.

摘要： A wireless endpoint is a Wireless Regional Area Network (WRAN) endpoint, such as a base station (BS) or customer premise equipment (CPE). The WRAN endpoint can transmit an orthogonal frequency division multiplexed (OFDM) signal comprising 2048 subcarriers in a channel. The 2048 subcarriers are divided into 16 subcarrier sets, or subchannels, each subcarrier set comprising 128 subcarriers. However, upon detection of an incumbent narrowband signal in the channel, the WRAN endpoint forms the OFDM signal for transmission in such a way that the WRAN endpoint excludes use of those one, or more, of the subcarrier sets that would interfere with the incumbent narrowband signal.
摘要翻译：无线终端是无线区域网络（WRAN）端点，例如基站（BS）或客户驻地设备（CPE）。 WRAN端点可以在信道中发送包括2048个子载波的正交频分复用（OFDM）信号。 2048个子载波被分成16个子载波组或子信道，每个子载波集包括128个子载波。然而，在检测到信道中的现有窄带信号时，WRAN端点形成用于传输的OFDM信号，使得WRAN端点排除使用将干扰现有窄带的子载波集中的那些或更多个信号。
