摘要： Provided are a physical downlink control channel (PDCCH)-based scheduling method and apparatus suitable for use by a base station in a long-term evolution (LTE) system. The scheduling method includes: determining an aggregation level of a common search space of a PDCCH by considering channel quality of a plurality of user equipments (UEs); identifying the number of PDCCH candidates and the number of messages, which require allocation of the common search space, based on the determined aggregation level and selecting messages by a smaller number of the number of messages and the number of PDCCH candidates; and allocating PDCCH resources and physical downlink shared channel (PDSCH) resources for the selected messages. In a situation where the PDCCH resources are shared by downlink scheduling information and uplink scheduling information of different UEs, the PDCCH resource-based scheduling method can be used by the base station to efficiently utilize the PDCCH resources.

摘要： There are provided a control channel managing apparatus of a base station, a control channel searching apparatus of a user equipment (UE) and a control channel allocating method in a mobile communication system. When an aggregation level is high and a plurality of UEs having the same starting address of a control channel search space are scheduled in a corresponding subframe, control information with respect to conflicting UEs which have lower priorities in terms of allocation of control information can be transmitted through the conflicting UE space. Hence, more control information can be transmitted and the number of available UEs corresponding to the control information increases, and thus an improvement in the performance of the entire network can be achieved.
