阅读说明：本技术 用于增强型覆盖的频率优先映射中的跳频 (Frequency hopping in frequency-first mapping for enhanced coverage ) 是由 杨阳 A·马诺拉克斯 J·孙 于 2018-05-15 设计创作，主要内容包括：本公开的某些方面涉及用于将经调制的码元映射到物理资源的方法和装置。本文描述的映射可以导致时间分集和频率分集两者。例如,一种用于无线通信的方法可以包括：在调度的时间单元内将码块的正交调幅(QAM)码元交替地映射到频率资源,其中该映射包括频率优先映射,其中该码块的各码元被交替地映射到第一正交频分复用(OFDM)码元集合中的该频率资源的第一子集,然后被映射到第二OFDM码元集合中的该频率资源的第二子集；以及基于该映射来传送该码块。(Certain aspects of the present disclosure relate to methods and apparatus for mapping modulated symbols to physical resources. The mapping described herein may result in both time diversity and frequency diversity. For example, a method for wireless communication may comprise: alternately mapping Quadrature Amplitude Modulation (QAM) symbols of a code block to frequency resources within a scheduled time unit, wherein the mapping comprises a frequency-first mapping in which symbols of the code block are alternately mapped to a first subset of the frequency resources in a first set of Orthogonal Frequency Division Multiplexing (OFDM) symbols and then to a second subset of the frequency resources in a second set of OFDM symbols; and transmitting the code block based on the mapping.)
