Abstract: The present invention relates to configuring search spaces of at least two coexisting control channels in a communication system. In particular, the control channels are defined in at least partially overlapping regions, wherein the overlapping is in the time and/or frequency domain. This configuration enables coexistence of the at least two channels in the same resource grid and better utilization of the resources. Furthermore, it enables sharing of the reference signals.

Abstract: The present invention relates to a method for receiving control information within a subframe of a multi-carrier communication system supporting carrier aggregation, the method comprising the following steps performed at a receiving node: performing a blind detection for the control information within a search space by means of a first search pattern, wherein the first search pattern is one of a plurality of search patterns, each of the plurality of search patterns comprising a plurality of candidates distributed on any of a plurality of aggregation levels, and wherein the plurality of search patterns further comprises a second search pattern whose candidates are non-overlapping the candidates of the first search pattern on the same aggregation levels.
Abstract translation: 本发明涉及一种用于在支持载波聚合的多载波通信系统的子帧内接收控制信息的方法，该方法包括在接收节点执行的以下步骤：对搜索空间内的控制信息执行盲检测， 第一搜索模式的装置，其中所述第一搜索模式是多个搜索模式之一，所述多个搜索模式中的每一个包括分布在多个聚合级别中的任一个上的多个候选，并且其中所述多个搜索模式 还包括第二搜索模式，其候选在相同聚合级别上与第一搜索模式的候选不重叠。
