利用lte/lte-a物理下行控制域闲置资源发送数据的方法

Method for sending data by using LTE/LTE-A (Long Term Evolution/Long Term Evolution-Advanced) physical downlink control domain idle resources

Abstract

The invention provides a method for sending data by using LTE/LTE-A (Long Term Evolution/Long Term Evolution-Advanced) physical downlink control domain idle resources. The method comprises the steps: acquiring a physical downlink data domain resource allocation object set and a physical downlink control domain time-domain span; judging whether physical downlink resource allocation objects meeting preset conditions exist in the physical downlink data domain resource allocation object set or not, and allocating the physical downlink control domain idle resources to the physical downlink resource allocation objects based on a base station scheduling algorithm; marking the physical downlink resource allocation objects which are allocated with the physical downlink control domain idle resources; carrying out channel coding on the physical downlink resource allocation objects which are allocated with the physical downlink control domain idle resources, so as to generate code words; carrying out scrambling, modulation, layer mapping and precoding on the code words, so as to generate a complex value sequence to be mapped; mapping the complex value sequence to be mapped to the physical downlink control domain idle resources and physical downlink data domain resources. According to the method, the transmission efficiency can be increased under the conditions of the same hardware and environment.
本发明提供一种利用LTE/LTE-A物理下行控制域闲置资源发送数据的方法,包括获取物理下行数据域资源分配对象集及物理下行控制域时域跨度的步骤;判断物理下行数据域资源分配对象集是否存在符合预设条件的步骤,基于基站调度算法将物理下行控制域闲置资源分配给物理下行资源分配对象的步骤;标识分配了物理下行控制域闲置资源的物理下行资源分配对象的步骤;将分配了物理下行控制域闲置资源的物理下行资源分配对象执行信道编码生成码字的步骤;将码字执行加扰、调制、层映射、预编码生成待映射复值序列的步骤;将待映射复值序列映射到物理下行控制域闲置资源与物理下行数据域资源上的步骤。本发明在同等硬件及环境条件下可提高传输效率。
