    • Methods and apparatus for allocating and hopping tones for uplink communications purposes in adjacent sectors and neighboring cells of an OFDM system are described. Physical tones used in each sector and cell are allocated to tone hopping sequences according to a tone to tone hopping sequence allocation function which uses both a cell identifier and sector identifier. Different sectors and cells use different tone to tone hopping sequence allocation functions through the use of different cell and/or sector identifiers to minimize the number of collisions between hopping sequences of adjacent sectors and neighboring cells. Uplink tone hopping sequences, corresponding to logical tones are allocated to uplink communications channels. Uplink communications channels are used by wireless terminals, e.g., mobile nodes, to transmit data to base stations. Over time, a wireless terminal uses the tones included in the uplink tone hopping sequences corresponding to uplink communications channels it is authorized to use.
    • 描述用于在OFDM系统的相邻扇区和相邻小区中用于分配和跳频用于上行链路通信目的的方法和装置。 根据使用单元标识符和扇区标识符的音调跳频序列分配功能,将每个扇区和小区中使用的物理音调分配给音频跳频序列。 不同的扇区和小区通过使用不同的小区和/或扇区标识符来使用不同的音调跳频序列分配功能来最小化相邻扇区和相邻小区的跳频序列之间的冲突次数。 对应于逻辑音调的上行链路跳频序列被分配给上行链路通信信道。 无线终端(例如,移动节点)使用上行链路通信信道来向基站发送数据。 随着时间的推移,无线终端使用与被授权使用的上行链路通信信道相对应的上行链路跳频序列中包括的音调。

    • Special DC tone treatment in a wireless communications system, e.g., an OFDM system, is discussed. In the downlink, a wireless terminal receiver introduces self -interference at the DC tone from the RP/ baseband conversion. A base station thus does not transmit on the downlink DC tone according to a predetermined pattern while continuing to transmit on other downlink tones. Wireless terminals measure received signal on the downlink DC tone during the time of suspended DC tone transmission, estimate self-interference and apply a correction to other received downlink DC tones, hi the uplink DC tone interference is a composite of the assigned wireless terminal transmitter's baseband/RF conversion self-interference and air link noise. During one symbol interval of an N symbol interval dwell, the uplink DC tone is reserved for a special modulation symbol, which is a predetermined function of the other N-I modulation symbols. At the base station, its receiver receives a set of modulation symbols conveyed by the uplink DC tone for a dwell, calculates the average DC component and corrects the received N-I modulation symbols.
    • 讨论了无线通信系统(例如,OFDM系统)中的特殊DC音调处理。 在下行链路中,无线终端接收机在RP /基带转换的DC音调下引入自干扰。 因此,在继续在其他下行链路音调上进行发送的同时,基站不会根据预定模式在下行链路DC音调上进行发送。 无线终端在暂停的直流音调传输期间测量下行链路直流音上的接收信号,估计自干扰并对其他接收的下行链路直流音调应用校正。在上行链路中,直流音干扰是指定的无线终端发射机的基带 / RF转换自干扰和空中链路噪声。 在N个符号间隔驻留的一个符号间隔期间,上行链路DC频调被保留用于作为其他N-1个调制符号的预定函数的特殊调制符号。 在基站,其接收机接收由上行链路DC频调传送的一组调制符号以进行驻留,计算平均DC分量并校正接收到的N-I调制符号。
