LTE载波聚合中的控制信令
摘要：
通过在主分量载波PCC上发送的PDCCH的数据部分上(即在物理下行链路共享信道PDSCH上)向UE发送次要分量载波SCC的资源的资源分配进行交叉载波调度。问题：对于可靠物理下行链路控制信道PDCCH运行，交叉载波调度可以根据主小区(主分量载波PCC)分配用于辅助分量载波SuppCC的资源而被使用。然而，可能发生在PDCCH的PDCCH拥塞或阻塞。解决方案：在主分量载波PCC的数据部分(即在PDSCH部分)发送次要载波SuppCC的资源分配。额外的实施方式：基于下行链路控制信息DCI格式类型盲解码控制信息(PDCCH)。搜索空间重配置。确定分配至辅助分量载波的物理资源块PRB。读取辅助分量载波上的PDCCH。配置PDCCH。聚合级别模式改变：聚合级别模式从第一等级改变到第二等级。
摘要（英）：

Cross-carrier scheduling by sending resource assignment of resources for a Secondary Component carrier, SCC, on the data portion (i.e. on the Physical Downlink Shared Channel, PDSCH) of the PDCCH sent on the Primary Component Carrier, PCC, to the UE. Problem: for reliable Physical Downlink Control Channel, PDCCH, operation, cross-carrier scheduling may be used from the primary cell (primary complement carrier, PCC) to allocate resources for the supplementary complement carrier, SuppCC. However, PDCCH congestion or blocking at the PDCCH may occur. Solution: sending the allocation of resources for the secondary CC, SuppCC, at the data portion (i.e. at the PDSCH part) of the primary complement carrier, PCC. Additional embodiments: blind decoding control information (PDCCH) based on downlink control information, DCI, format type. Search space reconfiguration. Determining physical resource blocks, PRB, allocated to a supplementary component carrier. Reading PDCCH on a supplementary component carrier. Configuring PDCCH. Aggregation level mode change: change an aggregation level mode from a first to a second order.
