    • A method, base station, and wireless communications system for interlacing Access and Backhaul frames in a Time Division Duplex wireless communication system. The method includes monitoring Access traffic and Backhaul traffic (604). Access traffic characteristics, Backhaul traffic characteristics, and corresponding frame control overhead information are determined in response to the monitoring (606). The method also includes determining an amount of time required to deliver a substantially equal amount of bearer Access traffic and Backhaul traffic (608). A frame interlacing ration is determined (608) in response to determining the amount of time required to deliver a substantially equal amount of bearer Access traffic and Backhaul traffic. A set of Access frames (302) and a set of Backhaul frames (304) are interlaced on a frequency band using the determined frame interlacing ratio.

    • Various embodiments are described to provide for the transmission of data in an improved manner. Data transmission is improved by including in a transmitter a null generator (310) to embed frequency domain nulls into a data symbol sequence to produce a null-embedded data symbol sequence. A symbol inserter (320) inserts a control symbol sequence into the frequency domain nulls of the null-embedded data symbol sequence to produce a combined symbol sequence. A modulator (330) then encodes the combined symbol sequence using IFDMA / DFT-S-OFDM. This approach allows the assignment of a single IFDMA / DFT-S-OFDM code to each user for data and control (pilot, e.g.) signaling, simplifying code management. Frequency hopping techniques may also be employed to lower the pilot overhead.
    • 描述了各种实施例以提供以改进的方式传输数据。 通过在发射机中包括空发生器(310)以将频域空值嵌入到数据符号序列中以产生空嵌入数据符号序列来改进数据传输。 符号插入器(320)将控制符号序列插入到空嵌入数据符号序列的频域中以产生组合符号序列。 调制器(330)然后使用IFDMA / DFT-S-OFDM对组合的符号序列进行编码。 这种方法允许为每个用户分配单个IFDMA / DFT-S-OFDM码,用于数据和控制(导频,例如)信令,简化了代码管理。 跳频技术也可以用来降低导频开销。
