    • Systems and methodologies are described that facilitate employing distributed frequency planning and reuse factor optimization based upon forward link and/or reverse link interference management techniques. An optimal reuse factor for a base station can be determined based upon a metric that evaluates levels of service associated with neighboring base stations. Moreover, a subset of available resource sets can be selected for use by the base station; thus, a base station specific collection of resource sets can be formed through such selection. Further, mappings of each resource set to a set of physical resources can be disseminated in a network or portion thereof. According to another example, frequency hopping can be constrained to use of resources within a resource set (rather than across more than one resource set) as provided in a base station specific hopping pattern.
    • 描述了有助于采用基于前向链路和/或反向链路干扰管理技术的分布式频率规划和重用因子优化的系统和方法。 可以基于评估与相邻基站相关联的服务等级的度量来确定基站的最佳重用因子。 此外,可以选择可用资源集的子集供基站使用; 因此,可以通过这样的选择来形成基站特定资源集合。 此外,每个资源集合对一组物理资源的映射可以在网络或其一部分中传播。 根据另一示例,跳频可以被限制为使用资源集合(而不是跨越多于一个资源集合)的资源,如在基站特定跳频模式中所提供的。

    • Techniques for efficiently sending data in a wireless communication system are described. Code division multiplexing (CDM) or orthogonal frequency division multiplexing (OFDM) may be selected for each traffic segment, which may correspond to specific time frequency resources. An output waveform comprised of traffic and overhead segments may be generated. Each traffic segment may carry CDM data at a chip rate if CDM is selected or OFDM data if OFDM is selected. OFDM symbols may be generated at a sample rate that may be an integer ratio of the chip rate and may have a duration that may be determined based on the traffic segment duration. The output waveform may carry CDM data and/or OFDM data on subcarriers corresponding to at least one carrier in a spectral allocation and may further carry OFDM data on remaining usable subcarriers in the spectral allocation.
    • 描述了用于在无线通信系统中有效发送数据的技术。 可以为每个业务段选择码分复用(CDM)或正交频分复用(OFDM),其可以对应于特定的时间频率资源。 可以生成由业务和开销段组成的输出波形。 如果选择CDM,则每个业务段可以以码片速率承载CDM数据,或者如果选择OFDM,则承载OFDM数据。 可以以可以是码片速率的整数比率的采样速率生成OFDM码元,并且可以具有可以基于业务段持续时间确定的持续时间。 输出波形可以在对应于频谱分配中的至少一个载波的副载波上携带CDM数据和/或OFDM数据,并且还可以在频谱分配中的剩余可用副载波上携带OFDM数据。
