摘要： The present invention relates to providing control information within a search space for blind decoding in a multi-carrier communication system. In particular, the control information is carried within a sub-frame of the communication system, the sub-frame including a plurality of control channel elements. The control channel elements may be aggregated into candidates for blind decoding. The number of control channel elements in a candidate is called aggregation level. In accordance with the present invention, the candidates of lower aggregation levels are localized, meaning that the control channel elements of one candidate are located adjacently to each other in the frequency domain. Some candidates of the higher aggregation level(s) are distributed in the frequency.

摘要： The present invention relates to rapid search space reconfiguration for E-PDCCH (Enhanced Physical Downlink Control CHannel) in wireless communication system to avoid flashlight interferences from neighboring cells and to allocate the E-PDCCH on the best physical resource blocks (PRBs) in frequency fluctuation dominated scenarios. To this end, a method for providing low-latency feedback on a reconfiguration attempt of a search space for an Enhanced-PDCCH, and a corresponding apparatus are provided. Specifically, a signaling scheme is provided that supports transmission of both HARQ-ACK for PDCCH based E-PDCCH reconfiguration and HARQ-ACK for PDSCH (Physical Downlink Shared CHannel) on the same uplink subframe, so that an acknowledgment of PDCCH based E-PDCCH reconfiguration information and PDSCH information can be transmitted on the same subframe.

摘要： Provided are a base station, whereby the erroneous detection of control information can be reduced, thereby preventing the degradation of the system throughput. A base station (100) maps a downstream allocation control information unit, which is addressed to a terminal (200), to a first resource region, which can be used for any of a downstream control channel region and a downstream data channel region, or to a second resource region, which can be used only for the downstream control channel, so as to transmit the downstream allocation control information unit. In the base station (100), a control unit (102) establishes a scale of the PDCCH region, and a transmission region establishing unit (131) establishes, on the basis of a scale value established by the control unit (102), a mapping region to which the DCI is mapped within the R-PDCCH region and the PDCCH region.

摘要： The invention relates to a method for dynamically controlling the PUSCH of a SCell in a backhaul link of a communication system utilizing a relay node with carrier aggregation, where the SCell is inband with respect to the access link between the relay node and the UEs. In order to avoid subframe blocking due to inband operation, the PUSCH of an SCell may be deactivated. The new downlink-only configuration of the SCell allows the relay node to use all resources of the SCell for scheduling resources for uplink and downlink transmissions in the access link. The PUSCH may deactivated and activated e.g. depending on the need for higher data rates in the uplink and downlink of the access link between the relay node and the UEs. The decision to deactivate/activate the PUSCH of an SCell may be taken by the DeNB or the relay node.

摘要翻译： 本发明涉及一种用于动态地控制利用具有载波聚合的中继节点的通信系统的回程链路中的SCell的PUSCH的方法，其中SCell相对于中继节点和UE之间的接入链路是带宽的。 为了避免由于带内操作引起的子帧阻塞，可以停用SCell的PUSCH。 SCell的新的仅下行链路配置允许中继节点使用SCell的所有资源来调度资源以用于接入链路中的上行链路和下行链路传输。 PUSCH可以去激活和激活。 这取决于在中继节点和UE之间的接入链路的上行链路和下行链路中需要更高的数据速率。 停用/激活SCell的PUSCH的决定可以由DeNB或中继节点进行。
