Abstract

本申请实施例提供了一种基于载波聚合的解调方法及装置，涉及无线通信技术领域，所述方法包括：当接收到UE基于调度的SCC发送的上行数据时，若当前时刻为周期CQI的上报时刻且在当前时刻之前需要确定对该上行数据进行解调的解调格式时未曾接收到该UE的PCC第一调度结果，则对该上行数据分别按照第一解调格式和第二解调格式进行解调，得到第一解调结果、第二解调结果、第一校验结果和第二校验结果；若在解调完成时已接收到该PCC第一调度结果，则基于该PCC第一调度结果、该第一解调结果、该第二解调结果、该第一校验结果和该第二校验结果，确定对该上行数据进行正确解调的解调结果。本申请提高了UE传输上行数据的可用资源，进而提高了上行数据的传输速率。
