    摘要： A method of operating a wireless communication device or a radio access node comprises addressing multi-subcarrier system resources using at least one of multiple different numerologies available within a single carrier, wherein the multiple different numerologies comprise a first numerology having resource blocks with a first bandwidth and a first subcarrier spacing, Δf1, and a second numerology having RBs with a second bandwidth and a second subcarrier spacing, Δf2, which is different from Δf1, and wherein the first numerology is aligned in the frequency domain relative to a frequency reference, Fref, according to m ∗ Δf1 + Fref and the second numerology is aligned in the frequency domain relative to the frequency reference, Fref, according to n ∗ Δf2 + Fref, where m and n are integers. The method further comprises transmitting and/or receiving information within the single carrier according to the at least one of the multiple different numerologies.

    摘要： A signal is received containing a block of multiple symbols, each symbol containing information bits spread by a spreading sequence of chips. Each spreading sequence is determined by a channelization sequence and a first or second complex-valued scrambling sequence of chips. Each block is processed using a set of spreading sequences using correlations between pairs of spreading sequences in the set. Spreading sequence correlation values between each pair are manipulated and stored in lookup tables. A lookup table address is determined using a first set of reduced basic scrambling bits to retrieve correlation values. The first set of reduced basic scrambling bits is based on manipulation of one set of the basic scrambling bits that reduces a number of bits included in the determined address to less than a number of binary values in the one set of basic scrambling bits. The one set of basic scrambling bits is used to construct one of the first and second complex-valued scrambling sequences. The retrieved correlation values may be used in mitigating spreading sequence correlation interference between spreading sequences in the set.

    摘要翻译： 接收包含多个符号块的信号，每个符号包含由码片扩展序列扩展的信息比特。 每个扩频序列由信道化序列和第一或第二复数值码片加扰序列确定。 使用一组扩频序列使用该组中扩频序列对之间的相关性对每个块进行处理。 每对之间的扩展序列相关值被操纵并存储在查找表中。 使用第一组简化的基本加扰比特来确定查找表地址以检索相关值。 第一组缩减的基本加扰比特基于对一组基本加扰比特的操纵，其将包括在所确定的地址中的比特的数量减少到少于一组基本加扰比特中的二进制值的数量。 一组基本加扰比特被用来构造第一和第二复数值加扰序列中的一个。 所检索的相关值可以用于减轻该组中的扩频序列之间的扩频序列相关干扰。
