Abstract

本发明实施例提供了一种确定控制信道搜索空间的方法。该方法包括确定用于传输增强物理下行控制信道EPDCCH的EPDCCH集合的编号；根据所述EPDCCH集合的编号，确定所述EPDCCH集合对应的搜索空间的位置偏移；根据所述EPDCCH集合对应的搜索空间的位置偏移，确定所述EPDCCH集合对应的搜索空间。本发明实施例还提供了一种确定控制信道搜索空间的装置。通过对EPDCCH的时频资源进行分组编号，根据所述编号以及不同的小区标识、UE标识来为不同的EPDCCH搜索空间确定不同的位置偏移，能够降低控制信道搜索空间冲突的概率。从而能够在多用户情况下最大化利用控制信道时频资源，提高通信效率。
