Title:
ＬＴＥキャリアアグリゲーションでの制御シグナリング
Document Type and Number:
Japanese Patent JP5961282
Kind Code:
B2
Abstract:
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.
